Full Text Available Aim: The objective of this study was to provide information on the level of utilization and satisfaction of residential university students with the dental services provided by the dental clinic of a teaching hospital. Volunteers and Material: A stratified sampling technique was used to recruit volunteers from the outpatient clinic of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Nigeria. Information was collected by a self-administered questionnaire composed of questions that measure the level of utilization and satisfaction with the dental services provided. Questionnaires were provided to 650 randomly chosen students residing in the University hostels. There were 39 refusals, and 6 incomplete questionnaires were discarded. This left a sample size of 605 volunteers. Results: Forty seven students (7.8% indicated that they visited the dental hospital within the last 12 months. Males and females utilized the dental services equally, and utilization increased with age and the number of years spent on campus. Anticipation of painful dental treatment, high dental charges, long waiting times and being too busy for a dental visit were cited as the most important impediments to seeking dental treatment. Females expressed greater satisfaction with the services. Conclusion: Dental service utilization among the students was found to be low. Oral health awareness campaigns, improving the quality of the services, and shortening the waiting time are expected to increase service utilization and satisfaction.

Oral health seeking behavior is compromised by dental anxiety, and affects quality of life. This preliminary study using convenience sampling was conducted among university students in the cities of Islamabad, Rawalpindi, and Multan, Pakistan, using standardized, valid and reliable scales to determine the prevalence and correlates of dental anxiety. Cumulatively 503 students including 278 males and 225 females, completed the questionnaire. High to severe anxiety on Dental Anxiety Scale-Revised was reported by 60 (21.6%) males and 54 (24%) females. Seventy-five (27%) males and 62 (27.6%) females reported being quite afraid to very afraid on Dental Anxiety Question. Results underline the need for population-based representative studies to determine the prevalence and correlates of dental anxiety for better dental health in Pakistan.
Full Text Available As the 21st century unfolds, the development of science-based technologies [such as nanodentistry, tissue engineering, three-dimensional (3D printers, laser dentistry, and computer-aided design/computer-aided manufacturing (CAD/CAM] should change clinical dental practice. Unfortunately, a persistent problem in dentistry is the slow acceptance of new technology by dental schools and some dentists. Most dental graduates, dental faculty, and dental researchers know little about the principles of entrepreneurship, e.g., the process of patenting and licensing, how to write a business plan, market analysis, sources of financing, and the establishment of small and medium-sized enterprises. Most dental graduates, dental faculty, and dental researchers know little about the topics mentioned above. They may know how to conduct a dental research project and publish a paper, but most have no idea of how to plan for the commercialization of research findings. University-industry research relationships are important in promoting innovation, and dental science and technology parks (STPs can play a major role in this technological revolution.

Calcic amphibole phenocrysts in the Tsurumidake summit (TS) lava, which was produced during the most recent eruption at Tsurumi Volcano (SW Japan) at around 7.5-10.5 ka, have been analyzed to determine the pre-eruptive conditions, such as temperature (T), pressure (P), oxygen fugacity (fO2), SiO2 content (SiO2melt), and FeO*/MgO ratio (FeO*/MgOmelt), of coexisting silicate melts in the magma reservoir beneath the volcano. Although most of the amphibole phenocrysts have been completely decomposed to a fine-grained opaque symplectite, 6% of the grains remain intact. The degree of amphibole breakdown (DAB), defined as the ratio of the area of symplectite to the area of symplectite plus relict amphibole in each phenocryst, varies from 20% to 100%. Compositional zoning was not observed in the amphibole grains, however, two distinct groups of amphibole phenocrysts have been identified based on their chemical compositions: group-I amphiboles, which are relatively Si-poor, and Al-rich, and have a relatively high Mg# [100Mg/(Mg + Fe2 +)]; and group-II amphiboles, which are Si-rich, and Al-poor, and have a relatively low Mg#. Empirical equations for geothermobarometry, oxygen barometry and chemometry that exclusively rely on the amphibole composition were applied to estimate the T-P-fO2-SiO2melt-FeO*/MgOmelt conditions of the silicate melts with which the amphibole crystals equilibrated. The results show that group-I and group-II amphiboles equilibrated with andesitic melts (group-I melts) and dacitic-rhyolitic melts (group-II melts), respectively. The T-P-fO2 conditions of group-I melts were estimated as 374-483 MPa ( 13.9-17.9 km depth), 950 °C, and NNO + 1.3, respectively, and those of group-II melts were 93-242 MPa ( 3.4-9.0 km depth), 824-913 °C, and NNO + 0.6-1.7, respectively. The estimated T-P-fO2-SiO2melt-FeO*/MgOmelt conditions were almost constant for group-I melts, whereas the T, ΔNNO, and FeO*/MgOmelt values of group-II melts decreased with increasing

Social inequalities in oral health exist in various countries. In Japan, a country with universal healthcare insurance policy, people can receive medical and dental care and pay only 10-30% of the total cost of treatment. Additionally, very poor Japanese can receive care without any charge, by the benefit of public assistance. These policies are considered to affect oral health inequalities. This study examined the association between using a dental prosthesis and household income among older Japanese people. Self-administered questionnaires were mailed to subjects as part of the Japan Gerontological Evaluation Study (JAGES) project in 2010. Of the 8576 people aged 65 years or more living in Iwanuma, Japan, 5058 responded. We used 4001 respondents with no missing values. We stratified into two groups by having 20 teeth or not. Then, cross-tabulation, univariate logistic regression, and multivariate logistic regression were conducted for these two groups. The covariates are sex, age, education, and size of household. Of the all respondents included in the analyses, poorer respondents tended to have lower proportions with 20 or more teeth, and 54.6% respondents used dental prostheses. In the respondents with 19 or fewer teeth, higher-income group tended to show significantly higher dental prosthesis use. But the poorest income group showed high prevalence of dental prosthesis use as same as highest income group. Multiple logistic regression among respondents with 19 or fewer teeth showed that after adjustment for sex, age, education, and size of household, compared with the respondents with annual incomes of US$ incomes of US$5000-9999 and US$10 000-14 999 had significantly lower odds ratios for using a dental prosthesis (OR = 0.48 [95% CI = 0.28-0.83], 0.56 [95% CI = 0.33-0.95], respectively). The other respondents did not show significant differences. Although universal healthcare insurance covered dental prostheses, a social gradient in dental prosthesis

The purpose of this study was to investigate the level of psychological stress as well as the perceived sources of stress among undergraduate dental students at the University of Jordan. The top perceived stressors were compared with those of a previous study that examined the perceived sources of stress among undergraduate dental students at the University of Jordan in the year 2000. Psychological stress was assessed using the General Health Questionnaire (GHQ-12). Perceived sources of stress were evaluated using the Dental Environment Stress questionnaire. In the study, 520 students completed the questionnaires, for a response rate of 74 percent. These students showed a high level of psychological stress, with 70 percent at the cutoff point of a score of more than 3 for the GHQ-12. Women had a higher level of stress than men: 73 percent scored more than 3 on the GHQ-12 vs. 63 percent for men, which was statistically significant at p=0.05. The top perceived sources of stress from the year 2000 were mostly unaltered in our study, despite a substantial increase in the number of students as well as changes in the curriculum. Further research is needed into methods to minimize stress on dental students.

To calculate associated costs with dental studies (ACDS) in a public university. We performed a cross-sectional study using a costing system on a random sample of 376 dental students enrolled at any semester in a public university. To calculate ACDS (Mexican pesos of 2009-1), we used a questionnaire divided into eight sections. Sociodemographic and socioeconomic variables, housing costs, food, transportation, instruments and equipment, as well as remunerations associated with patient care along 16 weeks of classes in each semester were included. We used linear regression. The average of ACDS was of 18,357.54 ± 12,746.81 Mexican pesos. The largest percentage of ACDS (30.2 %) was for clinical instruments (5,537.66 ± 6,260.50). Students also spent funds in paying to patients for their time during care delivered (2,402.11 ± 4,796.50). Associated variables (p 〈 0.001) with the ACDS were having completed at least one clinical course or one theoretical-practical course, living within the state or out of state (compared to students who live in the city where dental studies take place), and being enrolled in the more advanced dental studies. The results indicate that a significant percentage of the cost to students (13.1 %) is related with clinical care delivery.

Libraries have an exceptional place in the history, culture, education and scientific life of a nation. They collect all aspects of our linguistics and literacy, all out theoretical assumptions as well as all the results of experience and practice. The importance of a library is not mirrored only in the national and historical role and heritage, but in a more permanent, informational role, since a modern library must, above all, be an effective information system. Since a library of a university operates as a part of its matrix, it is easily shadowed by other forms of educational and scientific infrastructure. 50th anniversary of the Central Dental Library of the School of Dental Medicine University of Zagreb is an excellent opportunity to make a call to the institution and public to its unique and irreplaceable role.

The Ministry of Higher Education in Malaysia has called for the implementation of a soft skills module in all public universities in Malaysia. In response to this and as part of curriculum development efforts for a new integrated program for 2011, a study was undertaken to improve the University of Malaya (UM) Faculty of Dentistry's communication skills course. One of the study objectives was to investigate dental students' attitudes towards communication skills learning and the association between their attitudes and demographic and education-related characteristics. A cross-sectional survey--using a self-administered twenty-four-item adapted Communication Skills Attitude Scale (CSAS) that contained both positive (PAS) and negative (NAS) attitude subscales--was carried out targeting all final-year dental students at the UM and the Universiti Kebangsaan Malaysia (UKM). A total of 148 students completed the survey, yielding a response rate of 88.1 percent. Overall, UKM students had significantly more positive attitudes towards communication skills learning (PAS score: mean=48.69, SD=4.48, pattitudes between the two groups. UKM students with more positive attitudes tended to be female (pattitudes perceived themselves as poor communicators (pattitudes tended to have poor English proficiency (pattitudes towards learning communication skills. These attitudes were significantly associated with certain background and education-related attributes. Outcomes of this study served as a valuable guide in strengthening the communication skills course for the UM's new, integrated dental curriculum.

The authors conducted a study aimed to assess the awareness and attitude among dental students and residents at King Abdulaziz University, Faculty of Dentistry (KAUFD) toward using dental magnification. An e-questionnaire was formulated then sent to dental students and residents (n = 651). The questionnaire included questions that assessed both the awareness and attitude toward using dental magnification. Data were analyzed using IBM SPSS version 22. The chi-square test was used to establish relationships between categorical variables. The response rate was 69.7 % (n = 454). Of those, 78.1 % did not use magnification during dental procedures. However, 81.8 % agreed that dental magnification could enhance the accuracy and quality of their dental work. Thus, 91.6 % thought it would be useful in endodontics and 46.3 % voted for surgery. Of the 21.9 % that used magnification, dental loupes were mostly used, 55.9 %. The majority (59.4 %) of the participants believed that using dental magnification should be introduced by faculty beginning in Year I of dental school. Among our respondents, most of the undergraduate students did not use dental magnification nor attended courses in the use of dental magnifications. However, most of the students were aware of its significance in improving the accuracy and quality of their work.

In a general effort to facilitate dental professionals' effective tobacco-dependence education (TDE), the student part of the project reported here had three purposes: 1) to promote tobacco cessation activities in the dental school clinic, 2) to evaluate dental and dental hygiene students' confidence level in treating tobacco-dependent patients, and 3) to determine the frequency, duration, and depth with which the students assisted tobacco-dependent patients. Surveys of senior dental and dental hygiene students at the Loma Linda University School of Dentistry were conducted in 2008. Of the twenty-seven questions on the survey, nineteen related to the procedures students performed and questions asked of patients, one question asked how many minutes students spent counseling patients, and seven questions related to barriers to incorporating TDE activities. Only 56.5 percent of the responding dental students reported they routinely "asked and advised" about their patients' smoking behaviors, but 87.5 percent of the responding dental hygiene students reported they routinely did so. After the curricular intervention, the follow-up survey found that the dental students more frequently showed their patients the effects of tobacco on the oral mucosa and more frequently discussed pharmacotherapy options and made referrals during routine care. Until all dental and dental hygiene students are required to meet written board and clinical competencies in TDE and given adequate mentoring by clinical faculty to treat tobacco-dependent patients, the likelihood of seeing major improvements in tobacco-cessation treatment in dental practices is low.

A cross sectional study. 250 first visit patients seeking dental treatment. Modified Dental Anxiety Scale (MDAS), Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were used to assess the dental anxiety, general anxiety and depression level in these patients. The mean MDAS, BAI, and BDI scores were 10.5, 9.4, and 10.7, respectively. The prevalence of dental anxiety was found to be 20.8% (52/250) at the cut-off point > or = 15 and 6.8% (17/250) at the cut-off point > or = 19 according to MDAS score evaluation. MDAS and BAI scores were significantly higher in women (p or = 19 (p Dental anxiety was positively correlated with patients' general anxiety level and was higher in women and at younger age.
The incorporation of technological advancements in higher education has started to bridge the gap in local, national and global delivery of dental courses. This gap, including the global decrease in senior clinical academics, has influenced the development of new teaching and learning techniques. Institutional virtual learning environments (VLE) and other e-learning resources are now in higher demand. This paper describes how one such innovative solutions has been IVIDENT (International Virtual Dental School), has enabled secure and seamless access to high quality e-content and tools through an innovative, universal flexible learning platform. IVIDENT, now UDENTE (Universal Dental E-learning) has been shown to offer new learning experiences for students of dentistry, but its approach can apply across all educational domains. UDENTE also benefits staff as it allows them to contribute and access resources through peer reviewed publishing processes, which ensure the highest quality in education. UDENTE was developed thanks to a £2.3 million grant from the Higher Education Funding Council for England (HEFCE) and the Department of Health. http://www.udente.org. This academically led educational research project involved dental schools in seven countries. An initially scoping of requirements was followed by elaboration of the tools needed. Pilot testing of the tools, systems and learning resources in particular and the impact of the UDENTE in general were carried out. The pilots revealed evidence of positive impact of a space for learning, teaching, development and communication, with tools for planning of electives and administrative support. The results of these initial pilots have been positive and encouraging, describing UDENTE as an accessible, user friendly platform providing tools that otherwise would be difficult to access in a single space. However, attention to supporting faculty to embrace these new learning domains is essential if such technology enhanced

This study demonstrated that dental students have a lower degree of dental anxiety compared to psychology- and biology students. Senior dental students also have less dental anxiety than junior dental students. This indicates that the dentistry programme structure may influence dental anxiety levels.
Full Text Available Introduction: Dental students are the future leaders in oral health care and are expected to be teachers of oral hygiene as well as role models of self-care regimens for their patients. Objective: The objective was to assess self-reported oral health attitude and behavior among undergraduate dental students and to analyze variations between gender and level of education. Materials and Methods: A self-administered questionnaire based on the Hiroshima University-Dental Behavioural Inventory (HU-DBI was distributed among 270 undergraduate students which consisted of 20 dichotomous responses (yes-no. Data were analyzed using the analysis of variance and statistical significance was set at P < 0.05. Results: Females had better oral health attitude and behavior toward visiting the dentist and oral hygiene practices, mean HU-DBI score of 8.8 (P < 0.05. Furthermore, the preclinical students (1 st , 2 nd years had better oral health attitude and behavior especially towards gingival health, oral hygiene practices and visiting the dentist (P < 0.05. Conclusion: Among dental students, the overall attitude of oral health was good, even though there were deficits in a few areas. The oral health attitudes and behavior were better among female′s dental students and were not improved with increasing levels of education. Better comprehensive dental education with exposure to dental health and prevention is suggested to improve dental students′ oral health attitudes and behavior.

Full Text Available OBJECTIVE: This study was designed to investigate the subjective ratings of dental anxiety levels among university students enrolled at Jordan University of Science and Technology. In addition, the present study aimed to explore the sources of dental anxiety and the impact of gender on the perceived dental anxiety and the correlation between field of study and dental anxiety level. MATERIAL AND METHODS: The Modified Corah Dental Anxiety Scale was used to measure dental anxiety among the study population. Six hundred subjects were recruited into the study from Jordanian undergraduate students from the faculties of Medicine, Engineering, and Dentistry. RESULTS: Five hundred and thirty five complete questionnaires were returned, which accounts for a response rate of 89.2%. The totals of the mean anxiety scores were the following: Medical students, 13.58%; Engineering students, 13.27% and dental students, 11.22%. About 32% of the study population has scored 15 or more. Dental students had the lowest percentage of those who scored 15 or more. Surprisingly, the medical students were responsible for the highest percentage of those who scored 15 or above. Although women demonstrated statistically higher total dental anxiety scores than men (p= 0.03, the difference between both genders was small and could be clinically insignificant. The students were anxious mostly about tooth drilling and local anesthetic injection. CONCLUSIONS: Lack of adequate dental health education may result in a high level of dental anxiety among non-dental university students in Jordan. Further studies are required to identify the correlates of dental anxiety among university students.

To document the occurrence of cases of ameloblastic fibroma. A retrospective study. The Division of Oral Pathology and Oral Medicine histopathology laboratory at the Faculty of Dental Sciences, University of Nairobi, January 1991 to December 2000. Seven complete records of histopathologically confirmed cases of ameloblastic fibroma were identified. There were four male and three female cases with an age range of 10 to 22 years (mean=14 years). Remarkably, six of the cases had lesions in the molar regions of the mandible with a single case with a maxillary molar area lesion. One of the cases had the neoplasm associated with an unerupted tooth. From the clinical notes all the patients were managed by meticulous enucleation and curettage of the lesions. After follow up periods ranging from several months to eight years no recurrences had been recorded. Evidently ameloblastic fibroma is an uncommon neoplasm as noted in the earlier literature. Although the lesions can be quite extensive at the time of diagnosis, the recurrence rate appears to be relatively low if the neoplasms are meticulously extirpated.

To estimate the association between personality and dental anxiety among Finnish University students. A total of 880 university students in Finland returned the questionnaires addressing dental anxiety by using the Modified Dental Anxiety Scale (MDAS) questionnaire. In addition, the personality of traits (neuroticism, extraversion, agreeableness, conscientiousness and openness to experience) were noted. Personality traits of students were compared with the level (high, mild or none) of dental anxiety derived from the MDAS questionnaire. The relative odds of dental anxiety associated with the level of dental anxiety were estimated by logistic regression, Chi-Square tests and one-way analysis of variance (ANOVA). Median age of the respondents was 22 years. Of the respondents, 99 (11.3%) were classified as dentally anxious patients (90, 12.2% of females; 9, 6.6% of males)). Neuroticism was the only personality trait that was significantly associated with dental fear (p personality traits, neuroticism was a significant risk factor for developing dental anxiety, and this should be recognized in clinical practice.

Full Text Available The traditional morphological concept to dental care has shown many drawbacks and is not appropriate in many cases. To counteract these shortcomings, a problem-solving approach has been introduced in dental curriculum of Cantho University of Medicine and Pharmacy (CTUMP, Vietnam. This approach should be reflected in dental practice in CTUMP. Objective: To investigate the problem-solving approach to dental care of CTUMP by patterns of tooth extraction, and tooth rehabilitation. Methods: Cross-sectional data on DMF, dental treatments planned, dental treatments delivered from 1549 dental records of patients aged ≥18 of CTUMP were analyzed. Results: The majority of patients were aged 18-29 (929, 60%, classified as professional and skilled workers (1112 subjects, 72%, lived in urban areas (1156 subjects, 75%, and women (932, 60%. The number of teeth eventually receiving dental treatment was lower than the number of teeth indicated for the treatment. On average, each patient had 2 teeth receiving treatment. Tooth restoration was the most common treatment (1390, 70%. Molars were the most treated teeth (842, 43%. Molars showed statistically significant higher chance for restoration and extraction than premolars and anterior teeth (Wilcoxon-signed-ranks test p ≤ 0.017. No statistically significance was found in tooth replacement between premolar and molar regions. The dental treatments aimed to preserve all teeth regardless of dental regions. Tooth replacement may tend to be morphologically based rather than functionally as most prostheses restored the complete dental arch. Conclusions: The approach to dental care in CTUMP tends to be morphologically conservative.DOI: 10.14693/jdi.v22i1.376
Full Text Available Formal lectures have been a traditional part of medical and dental education, but there is debate as to their compulsory status. This study was designed to explore dental and medical students’ views on compulsory lectures and the use of Video-Recorded Lectures (VRL. A cross-sectional study of University of Bristol students in Years 2 to 4 was conducted using an online questionnaire. The majority of both dental (76% and medical (66% students felt lectures should be non-compulsory. The most common learning resources used by both dental and medical students were live lectures, lecture handouts and VRL. The majority of both dental (84% and medical (88% students used VRL. Most students attended lectures all of the time both before and after the introduction of VRL, even though most dental and medical students believe lectures should be non-compulsory. VRL is a popular learning resource. These findings tie-in with General Dental Council and General Medical Council recommendations that encourage self-directed learning. Dental and Medical schools should offer a range of learning resources and make use of current technology, including the use of VRL.

Satisfaction is important in dental care because satisfaction with care alleviates dental anxiety, influences patients' compliance and is an important indicator of quality of care. This study was designed to determine the factors that contribute to satisfaction with dental care among patients attending the Lagos State University (LASUTH) Dental Clinic. Across-sectional, descriptive questionnaire-based survey was conducted among adult patients attending the LASUTH Dental Clinic. The questionnaire, a modification of the Dental Satisfaction Questionnaire (DSQ), contained 19 items on a Likert-pattern scale with scores ranging from 0 to 4. The scores obtained for satisfaction with the dental services ranged from 19 to 75 with a mean of 55.30 +/- 11.55. The majority of respondents (305 or 87.4%) were satisfied with the services received. The items generating the highest and lowest mean satisfaction score were cleanliness/comfort of the facility and cost of services respectively. Long waiting time was the item respondents liked least about the services. There was a statistically significant relationship between the items assessing communication and respondent's gender (p = 0.001). The relationship between the overall satisfaction score and gender (p = 0.233), age category (p = 0.842) and educational status (p = 0.565) were not statistically significant. The results indicate a high level of satisfaction with services provided at the LASUTH Dental Clinic. However, there is need for improvement in communication with patients and reduction in waiting time.

To determine how prepared for dental practice graduates from the integrated problem-based learning (PBL) dental undergraduate curriculum at The University of Hong Kong (HKU) perceive themselves to be and to identify factors associated with self-perceived preparedness. A postal questionnaire was sent to five cohorts of dentists who had graduated from HKU's integrated PBL curriculum between 2004 and 2008. Using a 4-point Likert scale, the questionnaire assessed the self-perceived level of preparedness in 59 competencies grouped in nine domains. Responses were dichotomised into 'poorly prepared' and 'well prepared'. The response rate was 66% (159/241). The mean proportion (±standard deviation) of respondents indicating well-preparedness was 72.0±15.1% overall, and for each domain was as follows: general patient management, 93.1±12.1%; practice management, 81.0±22.2%; periodontology and dental public health, 73.5±19.3%; conservative dentistry, 92.5±13.1%; oral rehabilitation, 62.8±24.0%; orthodontics, 23.0±32.9%; managing children and special-needs patients, 64.8±28.9%; oral and maxillofacial surgery, 52.2±25.2%; and drug and emergency management, 84.7±22.6%. The odds of self-perceived well-preparedness were increased for cohorts graduating in 2004 and 2005 and graduates working in a non-solo dental practice. Dental graduates of HKU's integrated PBL curriculum felt well prepared for the most fundamental aspects of dental practice. However, apparent deficiencies of training in orthodontics and oral and maxillofacial surgery will need to be addressed by continuing education, postgraduate training and planning for the new 6-year undergraduate curriculum in 2012. © 2011 John Wiley & Sons A/S.

The objectives of this study were to evaluate the number and range of clinical procedures completed by undergraduate dental students in pediatric dentistry in Cork University Dental School and Hospital, Ireland, and to compare the number of procedures undertaken with the subsequent examination scores. The work comprised a retrospective audit of clinical logbooks for all of the undergraduate dental students in one cohort through their fourth and fifth clinical years between 2004 and 2006. Thirty-four quantitative logbooks were audited. Students had seen a total of 1,031 patients, and each student had completed a full course of dental treatment for an average of twenty-two children. Students completed means of 30.2 restorative procedures for children, fourteen in deciduous dentition (range six to twenty-eight), and seventeen in permanent dentition (range seven to twenty-eight). Continuity of education and care (measured through children having their treatment fully completed by the same student) was 72 percent. A moderate positive correlation between levels of clinical experience and exam score was identified. All students gained experience in management of child patients with students providing care for an average of thirty children and a minimum of nineteen.
Full Text Available BACKGROUND: Dental pulp is used for PCR-based detection of DNA derived from host and bacteremic microorganims. Current protocols require odontology expertise for proper recovery of the dental pulp. Dental pulp specimen exposed to laboratory environment yields contaminants detected using universal 16S rDNA-based detection of bacteria. METHODOLOGY/PRINCIPAL FINDINGS: We developed a new protocol by encasing decontaminated tooth into sterile resin, extracting DNA into the dental pulp chamber itself and decontaminating PCR reagents by filtration and double restriction enzyme digestion. Application to 16S rDNA-based detection of bacteria in 144 teeth collected in 86 healthy people yielded a unique sequence in only 14 teeth (9.7% from 12 individuals (14%. Each individual yielded a unique 16S rDNA sequence in 1-2 teeth per individual. Negative controls remained negative. Bacterial identifications were all confirmed by amplification and sequencing of specific rpoB sequence. CONCLUSIONS/SIGNIFICANCE: The new protocol prevented laboratory contamination of the dental pulp. It allowed the detection of bacteria responsible for dental pulp colonization from blood and periodontal tissue. Only 10% such samples contained 16S rDNA. It provides a new tool for the retrospective diagnostic of bacteremia by allowing the universal detection of bacterial DNA in animal and human, contemporary or ancient tooth. It could be further applied to identification of host DNA in forensic medicine and anthropology.

Traumatic dental injuries present complex injuries of the dentoalveolar system. Aim of this study was to investigate the frequency and patterns of traumatic dental injuries in a University dental emergency service over four years. A retrospective investigation on all dental trauma patients presenting at the dental emergency service of the University Medical Center Mainz, Germany between 01/2010 and 12/2013 was conducted. Demographic data, the cause and type of trauma and the initial therapy were analyzed. Out of 16,301 patients, 1,305 patients (8 %; average age 14.7 years ±15.7; 60.1 % male, 39.9 % female) came due to trauma. 63.9 % of the traumas occurred on weekends. The most frequent reason for injuries was falls (54.6 %). No correlation could be found between the cause and the kind of trauma. In 48.6 % of the cases only one tooth was involved, in 33.5 % two. The permanent dentition was traumatized in 56.6 % of cases, the deciduous teeth in 41.1 %. The most frequently affected tooth was the central upper incisor (61.0 %). Hard-tissue injuries were significantly more frequent in the permanent dentition, while periodontal injuries were seen significantly more often in the deciduous dentition. Eight percent of all patients seeking help at the dental emergency service presented with trauma, meaning that dental traumatology is one of the major topics in emergencies. To improve the quality of care, further public education, expert knowledge among dental professionals and a well-structured emergency service are necessary.

The aim of this study was to evaluate the socio-economic status of French undergraduate dental students. A 46-item questionnaire was completed by the dental students of six universities between 1992 and 1995. Subjects related to family background, housing, schooling, income, expenditure and participation in student life were investigated. A total of 1192 out of 1207 questionnaires were returned. Both genders had equal access to dental training. The average overall cost of the four last years of the dental course was 30,302 French francs and varied greatly between faculties, as did the number of hours spent at the faculty for lectures, tutorials and practicals, and clinical work. Overall, the majority of students came from a well off social background, and had a relatively high quality of life while a small minority received no support from their families. Thirty-four per cent of students had never worked. One third of students smoked and one third regularly consumed medication of some sort. A third did not participate in any sport. Only 25% students bought dental text books and 42% of the students reported using the library regularly. This study offers an accurate description of the socio-economic status of French dental students that could be used as a reference for comparable studies in other European countries.

A cross-sectional study of a cohort of 197 clinical dental students in the four accredited dental schools in Nigeria was conducted to determine the sociodemographic characteristics of these dental students and their motives for the choice of dentistry. The results indicate that the number of female dental students in Nigeria is increasing, which reflects a trend well established in virtually all other nations. The vast majority of Nigerian dental students (97 percent) qualified for school based on their performance on the University Matriculation Examination. About one-third, 32.5 percent, indicated that dentistry was their first choice for a career. This choice was greatly influenced by family in 50 percent of this group of students. There were several factors that strongly influenced career choice among students who indicated that dentistry was their first choice: interest, prestige, good employment opportunity abroad, and regular work hours. The need to go into a prestigious and financially lucrative profession similar to medicine were the commonest reasons identified by the group of students for whom dentistry was not the first career choice. The motives for choosing dentistry as a career in this group of students seem to relate to an image of dentistry as a vehicle for the achievement of personal goals. It is recommended that high school students be encouraged to see dentistry first hand. This is because in countries such as Nigeria it is not unusual for a potential dental student to have never visited the dentist.

The aim of this survey was to establish the current state of knowledge with regard to first-aid procedures and to compare the effectiveness of an educational lecture and a subsequent educational session. A questionnaire to assess the attitudes and anticipated behaviours of Sport University students related to first-aid procedures following dental injury was administered to the students 3 times (after 3 and 12 months). A lecture on the subject of dental trauma was given just after the first questionnaire survey. A randomly selected students group received an extra educational task. The present study revealed a low level of initial knowledge of physical education students concerning first-aid measures in the case of dental trauma. A 30 minute lecture and an extra educational task significantly improved the knowledge evel. Even after one year the knowledge level was still high and sufficient to properly react when faced with dental trauma. Our research proves that the inclusion of dental trauma as a topic in the Sport University students' curricular training and paedagogical education should be introduced in the form of a clear and concise lecture.

The aim of this study was to use the Hiroshima University - Dental Behavioral Inventory (HU-DBI) to compare oral health attitudes and behavior of dental and civil engineering students in Colombia. The HU-DBI's survey consisting of twenty dichotomous responses (agree-disagree) regarding tooth brushing, was completed at University Antonio Narino for the dental students and the University of Cauca for the civil engineering students. The Spanish version of the HU-DBI questionnaire was taken by 182 of 247 dental students and 411 of 762 engineering students. The data was-statistically analyzed by the chi-square test and backward logistic regression. Compared to the engineering students, the dental students were more likely to agree with questions such as "I am bothered by the color of my gums"(OR = 2.2, 95% CI: 1.3-3.7),"I think I can clean my teeth well without using toothpaste" (OR = 3.0, 95% CI: 1.5-5.9), "I have used a dye to see how clean my teeth are" (OR = 2.9, 95% CI: 1.9-4.3), and "I have had my dentist tell me that I brush very well" (OR = 2.0, 95% CI: 1.3-3.1). The dental education curriculum in a dental school compared to a civil engineering school in Colombia indicated that a three-phase curriculum in didactics and clinics increased oral health attitudes and behavior from entry to graduation.

To estimate the prevalence of tobacco, alcohol and drug use among dental undergraduates at one English university in 2008, and compare these with prevalence in 1998. Cross-sectional survey using an anonymous self-report questionnaire. In 2008 all 384 dental undergraduates at one English university were sent a questionnaire in order to obtain data on the frequency and amount of tobacco, alcohol, cannabis and other illicit drugs used before and during their time as a dental undergraduate. The same survey had been conducted on dental undergraduates at the university 10 years earlier. Tobacco smoking was reported by 27% of males and 13.5% of females, a reduction from 1998 (42% of males and 32% of females) being significant among females. 63% of males and 69.5% of females reported drinking alcohol: significantly fewer than in 1998 (82% males and 90% females). Binge drinking was reported by 69.5% of males compared to 56% in 1998. In females 66% binged compared to 58.5% in 1998. The increase in males was significant. 62% of males and 68% of females had never used cannabis compared to 38% in males and 50.5% of females in 1998, a significant reduction. A significant reduction in amphetamine use was reported among both male and female undergraduates in 2008 compared to 1998 and a significant increase in amyl nitrate use was reported by females. Reported illicit drug use was associated with alcohol drinking, and particularly with tobacco use. Dental undergraduates at one English university in 2008 when compared to those in 1998 are reported to be significantly less likely to drink alcohol, use cannabis and amphetamines. If female, they are significantly less likely to smoke tobacco and overestimate the number of units of alcohol they can safely consume in a week, but more likely to use amyl nitrate. If male, those who drink alcohol are significantly less likely to drink at a level of increased risk, but more likely to binge drink.

Many graduating dentists leave dental school feeling that they are not prepared to start and run a dental practice. The aim of this pilot study was to explore the knowledge and perceptions dental graduates have in the area of practice management. A twenty-item survey was mailed in the fall of 2008 to nearly half of the University of Michigan dental school alumni who had graduated between the years of 1997 and 2007. Respondents were asked about their demographics, practice characteristics, and perceptions of knowledge/experience regarding practice management skills at the present time as well as at graduation. Data were analyzed using descriptive and inferential statistics. The majority of respondents were general practitioners (84 percent) aged thirty to thirty-nine practicing between six and ten years with practice incomes reported to be greater than $300,000 per year (79 percent). Most dentists reported being either an owner or co-owner of the practice (57 percent), and 33 percent reported being an associate in the practice. Upon graduation, 7 percent of the respondents felt that they had a strong knowledge of accounting or human resource issues; this perception increased to 47 percent at the present time. Similarly, less than 6 percent of respondents felt they understood issues pertaining to dental insurance upon graduation; this perception increased to 68 percent after having spent time in the workforce. In contrast to the large increase in knowledge/experience in business aspects of dentistry that had accrued since graduation, most alumni reported only a 7 percent increase in their knowledge of the legal aspects of dental practice. Results from this study indicate that interventions are needed to increase graduating dentists' knowledge of practice management and close the gap between their knowledge and its application in real life. The majority of alumni believed there is a need to improve the curriculum focused on these aspects of dental practice.

Acidic soft drinks, including sports drinks, have been implicated in dental erosion with limited supporting data in scarce erosion studies worldwide. The purpose of this study was to determine the prevalence of dental erosion in a sample of athletes at a large Midwestern state university in the USA, and to evaluate whether regular consumption of sports drinks was associated with dental erosion. A cross-sectional, observational study was done using a convenience sample of 304 athletes, selected irrespective of sports drinks usage. The Lussi Index was used in a blinded clinical examination to grade the frequency and severity of erosion of all tooth surfaces excluding third molars and incisal surfaces of anterior teeth. A self-administered questionnaire was used to gather details on sports drink usage, lifestyle, health problems, dietary and oral health habits. Intraoral color slides were taken of all teeth with erosion. Sports drinks usage was found in 91.8% athletes and the total prevalence of erosion was 36.5%. Nonparametric tests and stepwise regression analysis using history variables showed no association between dental erosion and the use of sports drinks, quantity and frequency of consumption, years of usage and nonsport usage of sports drinks. The most significant predictor of erosion was found to be not belonging to the African race (p sports drinks and dental erosion. Copyright 2002 S. Karger AG, Basel

Dental faculties in Japan have organised many short-term international exchange programs to enable their undergraduates to study abroad. However, not many students apply for those programs. In this present study, we attempted to clarify the factors that discourage undergraduate dental students from studying abroad. We administered a questionnaire survey to 512 undergraduate dental students in three national universities located in different areas in Japan. Although 61.7% of the participants expressed interest in studying abroad, only 19.1% of them had prior experiences of study abroad or plans to do so. Their main worries were about lack of sufficient language ability in academic fields. Comparing those who were interested in studying abroad with those who were not revealed significant differences regarding their concern about lack of language ability and lack of specialised knowledge in dentistry. Participants who did not want to study abroad indicated that they did not perceive a purpose in doing so and cited not having foreign friends as a problem. Household income was significantly correlated with concerns about overall expenses. Overall, language ability and academic knowledge appeared to be the two strongest factors affecting dental students' consideration of studying abroad. Dental schools in Japan can use the findings of this study to improve their undergraduate exchange programs in such a way as to stimulate greater interest amongst their students. © 2016 John Wiley & Sons A/S.

Heavy metal concentration of river sediment in the light of the environmental quality standard value of Japan from the river in and around the Tokyo Japan: A case study at the Tama, Tsurumi, Edo and Ara rivers
Watanabe, K.; Matsumoto, I.
The river sediment is basically composed of clastic materials derived from the surface of the Earth. Purpose of our study is clarify the quantitative estimation of ratio of influence given to river sediment of nature and human activity by using of heavy metals. We show the geochemical and geological characteristics of stream sediments from the Tama, Tsurumi, Edo and Ara Rivers that flow in Tokyo bay, Japan. We show research results of the degree of contamination in above four rivers that are the relativery polluted river in Japan. Sediment samples collected from various points along the upper and lower streams were subjected to content analysis and elution analysis (using liquate (flow) out test) on the heavy metals like Cd, CN, Pb, Cr(6+), As and Hg from the river sediment for the purpose of environment assessment. Content of Cd, CN, Pb, Cr(6+), As, and Hg except Pb was above the environmental quality limit in few locations of the Tsurumi river. However, in the down-river part (mouth region) Pb-concentration was 10 times higher than at the source regions as the result of human impact; for Hg the same tendency was detected at the all rivers. This study is the first research that investigated river sediment in the light of the envirnomental quality standard in Tokyo area, Japan.

Full Text Available Aim of Study. To investigate dental anxiety levels among university students and its relation with their specialty and gender. Materials and Methods. 850 undergraduate university students were recruited into the study. The Modified Corah Dental Anxiety Scale (MDAS was used to measure the levels of their dental anxiety. 700 questionnaires were returned, 390 females and 310 males (response rate of 0.92% among females, 0.73% among males. The MDAS score ranged from 5 to 25. Patients were considered to suffer from high dental anxiety if they scored 13 to 20 points. Statistical analysis significance was set at P≤0.05. Results. Seven hundred students participated in this study including 13% of medical students, 10% of dental students, 58% of arts students, and 18% of computer science students. Medical and dental students were less anxious than arts and computer science students (P<0.05. Local anesthesia injection was the most fearful dental procedure (P<0.05. Females were more anxious than males (P<0.05. Conclusion. Male students were less anxious than female students. Students from medical background faculties were less anxious than students from nonmedical faculties. Lack of adequate dental health education may result in a higher level of dental anxiety among nonmedical students in Saudi Arabia.

Objective. To assess knowledge and awareness of oral cancer in the early identification of risk factors among undergraduate dental students. Methods. A total of 162 undergraduate (third, fourth, and fifth year) dental students at International Islamic University, Malaysia, were approached to participate in the study, and those who agreed were administered. A 9-item pretested questionnaire contains questions on oral examination, oral cancer risk factors, and requests for further information. Descriptive statistics were conducted using chi-square testing. Results. The response rate of the study was 70.3% (114/162), with 26 (22.8%) males and 88 (77.2%) females. All undergraduate dental students were familiar with examining the oral mucosa of their patients and most were likely to advise patients about the risk factors for developing oral cancer (98.2%). Nearly one-third (32.4%) of students reported examining patients with oral lesions as early signs for oral cancer (P oral cancer (P oral cancer. Further, 61.3% and 14.1% identified tobacco smoking and drinking alcohol as major risk factors for developing oral cancer. Conclusion. This study demonstrated lack of awareness about risk factors among undergraduate dental students regarding oral cancer. Reinforcing awareness and enhancing the benefits of early detection on prevention of oral cancer should be done through training and/or educational intervention. PMID:26839548

The aim of this study was to investigate dental health status and oral health behavior and associated factors among university students in five ASEAN countries (Indonesia, Malaysia, Myanmar, Thailand and Vietnam). Using anonymous questionnaires, data were collected from 3,344 undergraduate university students (mean age 20.5, SD=1.6; 58.3% female) from five ASEAN countries. Results indicate that 27.7% of students reported to have sometimes, most of the time or always having tooth ache in the past 12 months, 39.4% reported to have one or more cavities, 20.3% did not brush their teeth twice or more times a day, and 30.9% had never been to a dentist (or did not know it). In multivariate logistic regression analysis, older age, living in a lower middle income country, consumption of chocolate or candy, having made a dental care visit, and poor mental health was associated with tooth ache in the past 12 months. Being male, being 20 to 21 years old, coming from a wealthier family background, living in a lower middle income country, frequent consumption of soft drinks, not having consulted with a dentist in the past 12 months and weak beliefs in the benefits of tooth brushing were associated with inadequate tooth brushing frequency (

Failure to adopt a correct working posture can lead to occupational diseases. Evaluate knowledge in relation to ergonomics about BHOP concept and its application to routine clinical practice amongst undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain). A study based on interviews of undergraduate and postgraduate dental students in the University of Valencia (Valencia, Spain) was carried out. The information from a total of 336 interviews was used for the statistical analysis, differentiating according to gender and academic year: knowledge of ergonomics, pain prevalence and antecedents, assessment of the possible necessity for improved training in ergonomics, and evaluation of postural hygiene. Only 28.6% of the students were found to sit correctly in the dentist chair. Furthermore, in the opinion of the students, very few subjects during the career afforded adequate teaching in relation to ergonomics and working posture. The analysis of postural hygiene showed great variability. There were no significant differences in posture between males and females, although some incorrect postures appeared to be associated with the academic year (Ppostural hygiene were noted on progressing from one academic year to the next. The students in our study were not familiar with the principles of ergonomics and did not sit correctly in the dentist chair. Improved training in this field is required in dental school. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
Full Text Available Statement of Problem: Dental caries is one of the common diseases in the world. It is an infective disease which is caused by loss of minerals and destruction of dental tissues. One of the most effective ways to diagnose the interproximal caries is radiography.

The aim of this study was to describe the self-reported confidence levels of final year students at the School of Dentistry, Cardiff University and at the University Dental School & Hospital, Cork, Ireland in performing a variety of dental procedures commonly completed in primary dental care settings. A questionnaire was distributed to 61 final year students at Cardiff and 34 final year students at Cork. Information requested related to the respondents confidence in performing a variety of routine clinical tasks, using a five-point scale (1=very little confidence, 5=very confident). Comparisons were made between the two schools, gender of the respondent, and whether or not a student intended completing a year of vocational training after graduation. A response rate of 74% was achieved (n=70). The greatest self-reported confidence scores were for 'scale and polish' (4.61), fissure sealants (4.54) and delivery of oral hygiene instruction (4.51). Areas with the least confidence were placement of stainless steel crowns (2.83), vital tooth bleaching (2.39) and surgical extractions (2.26). Students at Cardiff were more confident than those at Cork in performing simple extractions (Cardiff: 4.31; Cork: 3.76) and surgical extractions (Cardiff: 2.61; Cork: 1.88), whilst students in Cork were more confident in caries diagnosis (Cork: 4.24; Cardiff: 3.89) fissure sealing (Cork: 4.76; Cardiff: 4.33) and placement of preventive resin restorations (Cork: 4.68; Cardiff: 4.22). Final year students at Cardiff and Cork were most confident in simpler procedures and procedures in which they had had most clinical experience. They were least confident in more complex procedures and procedures in which they had the least clinical experience. Increased clinical time in complex procedures may help in increasing final year students' confidence in those areas. © 2011 John Wiley & Sons A/S.

This study explored, and compared, the attitudes of student groups trained at the University of Portsmouth Dental Academy (UPDA) in 2010/2011 towards dental interprofessional education (IPE). The study population consisted of fifth-year student dentists (n = 80) from King's College London Dental Institute, second- and third-year dental hygiene and therapy (n = 38) and first-year dental nursing (n = 14) students from UPDA. A 19-item, validated and dentally modified questionnaire, 'Readiness for Inter-Professional Learning Scale (RIPLS)', was administered. RIPLS contains three subscales: teamwork and collaboration, professional identity and roles and responsibilities. Mean (x¯) and standard deviation (SD) of the scores were calculated, following reversal of negative items. All the analyses were carried out using SPSS version 20 and STATA version 11. An overall response rate of 71% (n = 94) was achieved. In reference to teamwork and collaboration, all groups strongly indicated that IPE can contribute to learning teamwork skills (x¯ = 24.98, SD = 3.5) and improving relationships with team members (x¯ = 12.93, SD = 1.63); however, the scores did not differ between the groups (P = 0.09 and P = 0.16, respectively). Concerning professional identity, student dentists had significantly higher preference for a discipline-based approach (P = 0.002); were more likely to agree that 'it is not necessary for undergraduate dental and dental care professional students to learn together' (P = 0.01); and perceived that 'clinical problem-solving skills can only be learnt effectively with other students from their own discipline' (P = 0.02) than dental hygiene and therapy students. In relation to roles and responsibilities, participants demonstrated a strong sense of their own professional role. Student dentists reported that they had 'to gain more knowledge and skills' than dental hygiene and therapy (P = 0.01) and dental nursing (P = 0.01) students. Dental hygiene and therapy

The aim of this study was to investigate the current knowledge, skills, and opinions of undergraduate dental students at the University of Jordan with respect to information communication technology (ICT). Dental students from the second, third, fourth, and fifth years were asked to complete a questionnaire presented in a lecture at the end of the second semester in the 2002-03 academic year. The response rate was 81 percent. Besides free and unlimited access to computers at the school of dentistry, 74 percent of the students had access to computers at home. However, 44 percent did not use a computer regularly. Male students were more regular and longer users of computers than females (pJordan have access to substantial IT resources and demonstrated attitudes toward the computer and Internet technology and use that were similar to other students in other nations. However, the educational use of ICT among Jordanian students remains low.

The objectives of this study were to determine the sources of stress among undergraduate dental students, and to compare the sources of stress among the 5 years of undergraduate study, between gender, and with other studies done elsewhere. A total of 325 students across the 5 academic years (88.8% response rate) of the Faculty of Dentistry, Universiti Kebangsaan Malaysia, completed the modified Dental Environment Stress questionnaire. All respondents reported that they experienced some form of stress. The preclinical students reported that examinations and fear of failure caused the most stress. The main stressor for clinical students was clinical training, particularly factors relating to meeting clinical requirements. Female students perceived more stress generally than male students. However, male students were more stressed when faced with factors related to clinical training.

Objective To assess smoking prevalence among dental students at King Saud University (KSU) and to determine possible risk factors of tobacco use. Methods A self-addressed invitation letter was sent to all dental students (males and females) at KSU requesting participation in this study. Data on smoking habits, associated risk factors, and demographic factors, such as age, marital status, residency status, the student’s year of study, and grade point average, were collected by an electronic self-administered questionnaire sent via email. Data were analyzed using SPSS. Significant differences between different groups were assessed with a Pearson Chi-Square test at α = 0.05. Logistic regression analysis was used to calculate the odds ratio (OR) and 95% confidence interval (95% CI) and to determine the effect of different risk factors on students’ smoking habits. Results Of the 600 registered dental students, 400 students responded (230 males, 170 females), representing a response rate of 67%. More male than female students were current smokers (27.6% vs. 2.4%, p students were about 4 times more likely to be smokers if all or most of their friends were smokers compared to students who had some friends who smoked (OR = 3.9, 95% CI = 1.9–7.7). A high proportion of current smokers (47.8%) reported stress as the main reason for smoking. Twenty-six percent of dental students (N = 87) who are currently nonsmokers reported that they have used tobacco at some point in their lives. Over two thirds of sampled students (63%) believed that public tobacco usage is not well addressed in the current college curriculum. Conclusion Approximately one in every four male dental students at KSU is a smoker. Having friends who are smokers was the most important risk factor associated with smoking. There is a general belief among dental students that public tobacco use is not well addressed in the dental college curriculum. PMID:25057228
Full Text Available Dentists are at risk of infectious diseases and dental offices can serve as a source of infection transmission if the infection control guidelines are not properly implemented. Adherence to infection control principles can help prevent disease transmission. This study sought to assess the level of knowledge and performance of dental students with regard to infection control principles in dental clinics of School of Dentistry, Mazandaran University of Medical Sciences. This study was conducted on 87 dental students. Data were collected using a 9-question questionnaire and a 16-item checklist. The data were analyzed using SPSS version 21 and descriptive statistics by calculation of mean and standard deviation (SD, t-test, Chi square test, Kruskal Wallis test and the Spearman’s correlation coefficient. Level of significance was set at P=0.05.Of subjects, 100% were wearing sterile gloves and changed them for each patient, collected and disposed wastes after examination or treatment of each patient, capped the needle after anesthetic injection and changed the dental suction tip; 94% were wearing a mask and changed it for each patient; 89% were wearing clean white coats. The level of knowledge of students was found to be moderate. Also, the performance of students with regard to infection control principles was found to be very good probably due to the rules and regulations set by the dental school departments.
Full Text Available Choronological age is assessed by the date, month, and year of birth. Several researches suggested that chronological age may not be able to provide sufficient information regarding on human growth precisely. Chronological age, on the other hand, could not be used to assess maturity development rate of a patient, so it is necessary to assess the dental age. Dental age is age assessment method by measuring human growth and development. Age estimation has important role in health field, particularly in dentistry as it will be beneficial in making appropriate diagnosis, treatment plan, and prognosis.

We investigated the effect of social networking (SN) on academic achievement of dental students at Jazan University, Saudi Arabia. A self-administered questionnaire was distributed during the 2015/16 academic year to all dental students and data were analysed by SPSS version 21. There were 348 participants (70% response rate) and 53% were male. Fifty-one percent of participants reported that they studied just before examinations, and 51% scored 3.5-4.5 Grade Point Average (GPA) in the last semester. Up to 98% of the participants reported using their smartphones/ computers for SN, with 93% doing so on a daily basis, and 66% reported SN during lectures, laboratories and clinics. Fifty-seven percent thought that SN affected their study negatively, and 65% thought that their GPA would improve if they stopped or reduced SN. Students who spent more hours each day on SN had lower GPA scores. SN negatively affected the academic achievement of dental students. Further evaluation and tailored educational programmes are needed to increase students' awareness about the negative effects of SN.

To investigate the current state of genetics education at the Fourth Military Medical University (FMMU) and compare it with other dental schools of China. Detailed information about the history and current education status of Oral Genetics in the FMMU were collected and questionnaires were completed to acquire the feedback of twenty-seven students on the course. In the other thirty-five dental schools including the capitals of twenty-five provinces and four municipalities in China, information about the oral genetic course were collected by a telephone survey. The contents of survey included whether or not the Oral Genetic course is offered and some basic information about the curriculum (such as the content, hours, teachers' background and teaching methods). Among a total of thirty-six dental schools investigated, six of them (16.7%) offered the Oral Genetic course or related lectures/seminars. The length and contents of the curriculum vary among these schools. The FMMU offered the oral genetic curriculum both to undergraduates and graduated students. Their teachers had a broad range of backgrounds, such as dentistry, biology, genetics, and biochemistry. The students considered the Oral Genetics course to be helpful for their future professional careers. Genetic education in dentistry in China is still at a preliminary stage. More effort must be paid to spread the knowledge of Oral Genetics in China. In addition, domestic and international communications and networks for Oral Genetics should be set up in the near future.

First-year university students are in a new, independent life situation, which may affect health behaviour, including oral health habits. The aim of this study was to evaluate the association between dental fear and oral health habits, while considering the simultaneous effects of attitude toward food and treatment need at dental check-ups. The data (n = 8514) for this national cross-sectional study were collected from health registers of Finnish Student Health Service. As part of health examination all first-year university students in Finland were sent an electronic questionnaire asking about general, psychological and oral health, and health habits. Dental fear was measured by the question: "How afraid are you of visiting a dentist?" (reply alternatives: "Not at all", "Somewhat" and "Very"). Chi-square tests and Multiple logistic regression analyses were used to determine the associations between dental fear and oral health habits (tooth brushing, tobacco use, frequency of eating and drinking, eating habits and interval between dental check-ups) as well as attitude to food and treatment need at dental check-ups while controlling for age, gender, general mood and feelings in social situations. Of the oral health habits, tooth brushing and tobacco use were associated with dental fear. Those who brushed their teeth once a day or less often or used tobacco regularly were more likely to have high dental fear than those who brushed their teeth twice a day or more often or used tobacco occasionally or not at all. Students who reported not having a normal attitude to food were more likely to have high dental fear than were those reporting normal attitude to food, but the frequency of eating and drinking was not associated with dental fear. Students who reported needing treatment frequently or at every dental check-up were more likely to have high dental fear than those who reported rarely or never needing treatment. Those students with high dental fear seem to be at

The present study reports the results of a structured survey of graduates intending to evaluate the education at the Dental School of the University of Basel in the years from 2006 to 2014. In addition, dentists and practice owners supervising graduates from Basel in daily clinical routine or hiring them as assistant dentists were questioned. The aims of the current survey were (1) to analyze own subjective experiences, (2) to assess potential differences between the cohorts prior to and after the implementation of the Bologna reform, (3) to compare the rating regarding theoretical knowledge and practical skills, and (4) to disclose potential for improvement. It was found that according to both their own assessment and the rating of the practice owners, graduates possess the basic dental expertise. The alumni rated their theoretical knowledge higher than their clinical practical skills and indicated a potential for intensification in the fields of dental surgery and implantology. When comparing the cohorts who had completed their studies according to the old (until 2010) and new study regulations, there were only minor differences; the own skills related to patient information about treatments were better rated by alumni who had been trained according to the new study regulations. The curriculum leading to the Master of Dental Medicine at the University of Basel fundamentally prepares graduates for the professional activity, but the additional acquisition of clinical experience in daily practice is indispensable.
Full Text Available In Japan, comprehensive food education (shokuiku programs are carried out with the aim of improving dietary practices and thereby reducing the incidence of lifestyle-related diseases, including dental caries. The purpose of this prospective cohort study was to investigate the association between knowledge about shokuiku and the increase in dental caries among Japanese university students who had attended a shokuiku program while in junior/senior high school. A total of 562 students volunteered to undergo oral examinations over a three-year follow-up period, during which the number of cases of dental caries were recorded. Additional information was collected using a questionnaire survey regarding knowledge about shokuiku, dietary habits, and oral health behaviors. In logistic regression analysis, males who lacked knowledge about shokuiku had significantly higher odds for dental caries than those who did not (odds ratio (OR, 2.00; 95% confidence interval (CI, 1.12–3.58; p = 0.019. On the other hand, among females, those who frequently consumed sugar-sweetened soft drinks had significantly higher odds for dental caries than those who did not (OR, 1.89; 95% CI, 1.05–3.42; p = 0.035. These results suggest that having no knowledge about shokuiku is associated with a risk of increase in dental caries in Japanese male university students.

Summary Adhesive dentistry has undergone great progress in the last decades. In light of minimal-invasive dentistry, this new approach promotes a more conservative cavity design, which relies on the effectiveness of current enamel-dentine adhesives. Adhesive dentistry began in 1955 by Buonocore on the benefits of acid etching. With changing technologies, dental adhesives have evolved from no-etch to total-etch (4th and 5th generation) to self-etch (6th, 7th and 8th generation) systems. Currently, bonding to dental substrates is based on three different strategies: 1) etch-and-rinse, 2) self-etch and 3) resin-modified glass-ionomer approach as possessing the unique properties of self-adherence to the tooth tissue. More recently, a new family of dentin adhesives has been introduced (universal or multi-mode adhesives), which may be used either as etch-and-rinse or as self-etch adhesives. The purpose of this article is to review the literature on the current knowledge for each adhesive system according to their classification that have been advocated by many authorities in most operative/restorative procedures. As noted by several valuable studies that have contributed to understanding of bonding to various substrates helps clinicians to choose the appropriate dentin bonding agents for optimal clinical outcomes.

Full Text Available Background: Dental anthropology is a new field of study in Indonesia, hence there are few numbers of research that can be found in this field. Knowledge in this field is needed due to the large area and diversity of the people. Moreover, knowledge regarding the possibility to differentiate the sexes of skeletons is still needed for the purpose of identification. Purpose: This research intended to study the differences in mesio-distal measurements of the teeth of Deuteromalayid Javanese males and females studying in the Faculty of Dentistry in Airlangga University. Methods: This study used mesiodistal metric dental data, using dental caliper, to test the existence of sexual dimorphism. Sample were teeth of freshman students of the Airlangga University, from 52 individuals comprising 26 males and 26 females Deuteromalayid originated from Java (Indonesia studying in the Faculty of Dentistry Airlangga University. Measurements were not performed on damaged casts due to caries or other reasons. Differences between males and females were tested using independent t-test. Results: The mean of mesiodistal measurements in males and females differs, where the males have greater size of mesiodistal measurements. The results showed that there were significant differences between sexes in the sample, in all field of teeth except the second upper and lower premolars. Reverse sexual dimorphism-female teeth measurement is larger than those of males-has not been found in these samples. The result of this study revealed that the range of mesiodistal measurements of every tooth in males and females overlapped. Conclusion: It is concluded that teeth measurement of males is bigger than females, except maxillary and mandibular second premolars.

Research in the context of the dental school has traditionally been focused on institutional/faculty accomplishments and generating new knowledge to benefit the profession. Only recently have significant efforts been made to expand the overall research programming into the formal dental curriculum, to provide students with a baseline exposure to the research and critical thinking processes, encourage evidence-based decision-making, and stimulate interest in academic/research careers. Various approaches to curriculum reform and the establishment of multiple levels of student research opportunities are now part of the educational fabric of many dental schools worldwide. Many of the preliminary reports regarding the success and vitality of these programs have used outcomes measures and metrics that emphasize cultural changes within institutions, student research productivity, and student career preferences after graduation. However, there have not been any reports from long-standing programs (a minimum of 25 years of cumulative data) that describe dental school graduates who have had the benefit of research/training experiences during their dental education. The University of Manitoba Faculty of Dentistry initiated a BSc Dent program in 1980 that awarded a formal degree for significant research experiences taking place within the laboratories of the Faculty-based researchers and has continued to develop and expand this program. The success of the program has been demonstrated by the continued and increasing demands for entry, the academic achievements of the graduates, and the numbers of graduates who have completed advanced education/training programs or returned to the Faculty as instructors. Analysis of our long-term data validates many recent hypotheses and short-term observations regarding the benefits of dental student research programs. This information may be useful in the design and implementation of dental student research programs at other dental schools.

Lack of knowledge is the major reason for non-compliance with correct healthcare-associated infections (HAI) prevention procedures. The aim of this study was to evaluate knowledge of the Dental School (DSS) and Dental Hygiene (DHS) students with regard to the prevention of HAI, as basic knowledge for improving and harmonizing the educational content in the different Italian Universities. A cross-sectional study was carried out using an anonymous questionnaire that was completed by DSS (I, II, III, IV, and V year) in seven Universities and DHS (I, II, and III year) in three Universities. The questions dealt with three specific areas: healthcare-associated infections, standard precautions and hand hygiene. Factors associated with an unacceptable level of knowledge (score <17.5) were analyzed using a logistic regression model. A p value <0.05 was considered to be significant. Five hundred and four questionnaires were collected: 81.5% for DSS and 18.5% for DHS. Mean overall score (±DS) achieved by the total number of students was 18.2±2.93 on an overall perfect score of 25; 18.2±3.04 for DSS and 17.8±2.31 for DHS. Stratifying by area, the average score 2.7±1.07 (53%) for HAI, 10.3±1.61 (85.9%) for standard precautions, and 5.2±1.44 (64.8%) for hand hygiene was observed. A significantly different level of knowledge (p<0.001) between DSS and DHS was observed only for HAI (2.8±1.07 for DSS vs 2.1±0.96 for DHS). Significant differences among the academic years were found only for DSS concerning HAI and standard precautions. The logistic regression model showed that an age <23 years was a risk factor for lack of knowledge on HAI, but a protective factor for lack of knowledge about standard precautions and hand hygiene; attending DH degree course was associated with lack of knowledge on HAI. Although the overall score obtained both by DSS and DHS indicated an acceptable level of knowledge, lack of knowledge was highlighted, in particular, for hand hygiene. Therefore

Aim To investigate the career intentions, work-life balance and retirement plans of dental undergraduates at the University of Bristol in 2015.Method Cross-sectional survey of 210 clinical undergraduates using an anonymous self-report questionnaire.Results The response rate was 79%. The majority (81.7%) were 'satisfied' or 'extremely satisfied' with their choice of career. The majority (78.7%) felt men and women are equally likely to succeed in dentistry, although 42.9% felt men had an advantage over women with regards to career success. The majority (81.6%) intend on working within general practice, 11.3% within hospital dental services and 2.1% within community dental services. The majority (70.5%) intend to specialise within dentistry. Only 1.8% of participants intend on providing only National Health Service (NHS) dental treatment whereas the 86.5% would provide both NHS and private dental treatment. Fifteen years after qualifying, 52.2% plan to work part-time, and 37.8% intend on retiring at the age of 60 or below. The majority (86.6%) felt that childcare should be shared equally between both parents. Female students intend to take more time out of their career to concentrate on childcare and felt that having a child would affect their career more than males.Conclusion The anticipated career plans, work-life balance and retirement plans of undergraduates change over time, and further research should be carried out to monitor future career intentions of dental students in order to help with dental workforce planning.

Dental care plays an important role in the multidisciplinary approach, which is used in palliative and long-term care to address the complex needs of terminally ill patients. The aim of this study was to assess the utilisation of dental services in a University Hospital Palliative and Long-term Care Unit. Over an observation period of 13 months, structured questionnaires were filled in after each dental appointment. The survey covered three main topics: the initiation and incentive from the dental consultation, particular difficulties because of the patient's health or the hospital's organisation as well as the accomplished treatment. Two hundred and seventy-five questionnaires from a total of 102 patients were available for analysis. The patients' median age was 83 years (SD 10.3, range 49-101 years), 63 were female, 39 male. A majority of first appointments were initiated by a physician (n = 49 of 102), mainly because of pain (n = 62 of 275). 10.5% of the appointments were cancelled on the same day. Only one-fifth of the patients were able to reach the practice on foot. Six used a walking stick and 54 relied on a wheelchair. Eighteen patients needed to be seen in their bed. The most frequently performed procedures were extractions and removal of denture sore spots (n = 67 of 275) followed by the manufacturing of new dentures (n = 38 of 275). In more than 17% of the appointments, no particular treatment was performed. The utilisation of dental services in terminally ill and severely compromised elderly patients shown justifies a dental service in a palliative care or geriatric hospital setting. The particular dental work profile requires a practitioner with empathy and professional experience.

The aim of the present study was to assess awareness of the risk of cross-infection and infection-control measures practiced in dental clinics for patients attending the outpatient dental department (OPD) at University Dental Hospital, Peradeniya, Sri Lanka. A descriptive cross-sectional study was carried out among 427 patients who attended the OPD clinics at University Dental Hospital. An interviewer-administered questionnaire was used to collect data, and chi-squared-test of association was applied where appropriate. Most patients (75.2%) were aware that there was a chance of infection transmission during dental treatments, and nearly 72% stated that wearing gloves and masks by their dentists was important during dental treatment. Awareness was higher among patients with a higher educational level. Participants revealed their fear of potential transmission of blood-borne pathogens in the dental setting. Awareness of sterilization of dental instruments was poor. The public should be made aware of the possible risks of cross-infection and the importance of infection-control practices in dental clinics. Dental professionals should fill the information gap. © 2017 John Wiley & Sons Australia, Ltd.

In Italy there is about one undiagnosed case of diabetes for each known case. The dental office might represent an important setting for screening the glycemic status of patients. The aim of the present study was to evaluate the effectiveness of dental chair-side capillary blood sampling for the identification of undiagnosed hyperglycemia in a group of Italian patients. Five hundred fifteen patients >45 years old consecutively visiting a public university dental clinic, where admission is regulated by medical or income criteria, were considered for the study. Demographic data, medical history, time of the last caloric intake and waist width were recorded for each participant. All participants underwent an oral examination. Glycemic values were obtained by capillary blood glucose testing. Of the 400 subjects who took part in the study, a low percentage of unaware diabetic individuals (1.7%) was identified. Inclusion criteria restriction to subjects between 50 and 75 years of age and a waist circumference >92 cm would have resulted in a proportion of diabetic patients of 4.3%. Dental chair-side in a public university clinic in Italy failed to disclose the expected number of unaware diabetic patients.

The purpose of this study was to investigate the demographic patterns of maxillofacial prosthetic treatment to identify the characteristics and geographic distribution of patients with maxillofacial prosthetics in the capital region of Korea. This retrospective analytical multicenter study was performed by chart reviews. This study included patients who visited the department of prosthodontics at four university dental hospitals for maxillofacial prosthetic rehabilitation. Patients with facial and congenital defects or with insufficient medical data were excluded. The patients were classified into three categories based on the location of the defect. Patients' sex, age, and residential area were analyzed. Pearson's chi-square test with a significance level of 0.05 was used to analyze the variables. Among 540 patients with maxillofacial prosthetics, there were 284 (52.59%) male patients and 256 (47.41%) female patients. The number of the patients varied greatly by hospital. Most patients were older than 70, and the most common defect was a hard palate defect. Chi-square analysis did not identify any significant differences in sex, age, and distance to hospital for any defect group (P>.05). The results of this study indicated that there was imbalance in the distribution of patients with maxillofacial prosthetic among the hospitals in the capital region of Korea. Considerations on specialists and insurance policies for the improvement of maxillofacial prosthetics in Korea are required.

The diagnostic imaging examinations in all 29 dental university hospitals in Japan were analyzed during a 1-year period from April 1999 to March 2000. The total number of patients examined was 790859, which corresponded to 27271 patients per hospital on average, with a range from 7872 to 62904. Relative to the total number of patients, intraoral radiography was found to have been most frequently performed, 59% on average, with a range from 40% to 80%, depending on the hospital. Extraoral radiography, mostly panoramic radiography, was 36% on average with the range from 18% to 56%. A significant inverse correlation was observed between the percentages of intraoral and extraoral radiography, relative to the total number of all types of imaging examinations. Computed tomography (CT) examinations were performed with their own apparatuses in 27 hospitals with a frequency of 2.9% of patients in all imaging examinations on average and 9.1% at maximum. The scanning parameter of milliampere seconds (mAs) for individual types of routinely performed CT examinations varied widely, and thus the patient dose can be expected to be considerably reduced, without reducing the amount of diagnostic information to be obtained. Other imaging examinations performed were magnetic resonance imaging in 11 hospitals, X-ray fluoroscopy in 8 hospitals, ultrasonography in 20, nuclear medicine in 5, and bone densitometry in 1 hospital.

The aim of this study was to evaluate the psychomotor skills of the dental students at University Complutense of Madrid (UCM), using a battery of psychometric tests. The sample comprised 306 students of the 1st, 2nd, 3rd and 4th years of Odontology, who, during the last month of the academic term, took the test on rotation of solid shapes, the Embedded Figures test in its group form (GEFT), the O'Connor Tweezer test, the MacQuarrie test for mechanical ability and the indirect vision test. Before these tests began, some personal data of all students were collected. The results showed some statistically significant correlation between several personal variables (sex, manual dominance and previous skills) and performance in the psychometric tests, although no significant relation was found between these variables and the students' academic qualifications. When comparisons were made between the psychomotor tests and the academic results of the students, significant differences appeared in the tracing and dotting subtests of the MacQuarrie test, whereby those students with higher practical qualifications reached the best punctuation. In the O'Connor Tweezer test, the students who obtained the worst results were those with lower qualifications. These data could serve to detect at an early stage those students who need greater educational support. No relation was found between the GEFT and the indirect vision test.

To assess the students' perception regarding mentoring at different stages of their studies at a private-sector medical college. The cross-sectional study was conducted from April 2012 to July 2014 at Bahria University Medical and Dental College, Karachi, and comprised students from first to fourth year. Data was collected through a self-administered questionnaire, which was developed after literature search and discussion. The total score for the 35 questions was used as the 'perception score' for the students. The perceptions among all students in an academic year were compared using the Kruskall-Wallis test for median score differences. Of the 401 students approached, 341(85%) completed the survey. The median perception scores for personal support (p=0.81) and career advice (p=0.07) were not different across the four years. There was a significant difference in the perception scores for role modelling (pStudents in pre-clinical years (1st/2nd years) rated their mentors higher on role modelling aspects of mentoring (pstudents' perception varied among preclinical and clinical groups when it came to the matter of career advising and role modelling.

An equitable and positive learning environment fosters deep self-directed learning in students and, consequently, good practice in their profession. Although demotivating weaknesses may lead to repeated day-to-day stress with a cascade of deleterious consequences at both personal and professional levels, a possible relationship between these parameters has not been reported. This study was undertaken to determine the relationship between students' perceptions of their educational environment and their stress levels. Sixty-one first year students at the Dental Faculty, University of Malaya, Malaysia participated. The Dundee Ready Education Environment Measure (DREEM) was used to determine educational environment while self-rated perceived stress level was measured by the Depression Anxiety Stress Scale (DASS). Most students (62.39%) showed positive perceptions for the total and five domains of DREEM. The highest percentage was observed for "Students perception of learning" (64.04%) while the lowest was for "Students' social self-perception" (60.32%). At the same time, 61% of students showed high perceived stress levels. However, this was not associated with their DREEM scores. Although a positive perception of their educational environment was found, minor corrective measures need to be implemented. Furthermore, longitudinal studies on an annual basis would provide useful input for strategic planning purposes.

Full Text Available Background. Dental students are seen as role-models for promoting good oral health behaviour, yet there is little published evidence in South Africa (SA that describes student knowledge and attitudes towards their own oral healthcare. Objective. To investigate undergraduate dental therapy and oral hygiene students’ knowledge and attitudes towards their self-care practices and the perceived influence of the dental curriculum on these practices. Methods. This was a descriptive survey of 64 undergraduate dental students at the University of KwaZulu-Natal, Durban, SA. A self-administered questionnaire was used for data collection. Results. Fifty-two respondents returned the completed questionnaires, yielding an 81% response rate. Almost all respondents (n=30; 96.8% (2nd-year students, and n=21; 100% (3rd-year students indicated the use of toothpaste and toothbrush to clean their teeth. Most respondents reported cleaning their teeth from 1 to 5 minutes, with 52% (n=27 reporting 1 - 2 minutes and 42% (n=22 3 - 5 minutes. Only three respondents reported cleaning their teeth for >5 minutes (n=3; 6%. Other practices included the use of toothpicks (n=12; 23%, dental floss (n=42; 81%, and interdental brushes (n=5; 10%. Almost all respondents (n=50; 96% indicated the use of commercially available mouth rinses. All 2nd-year students (n=30 and 90% of 3rd-year students (n=18 agreed that exposure to clinical training increased their awareness of self-care practices. Conclusion. Respondents reported good knowledge and practice of oral health self-care, but there were inconsistencies in these practices. Respondents also agreed that the dental undergraduate curriculum did influence their knowledge and oral health self-care practices.

The aims of the study were to audit the number and types of clinical procedures completed by the undergraduate dental students in the paediatric dentistry course at the University of Jordan Dental School and to present data on self-reported confidence in a variety of aspects of paediatric dentistry. A retrospective audit of clinical logbooks for the entire class of 120 dental students in their fifth clinical year was performed. Key clinical procedures performed in the paediatric clinics were recorded including treatment performed on both primary and permanent teeth. Students were requested to complete an anonymous questionnaire to assess confidence related to six activities using a visual analogue scale (VAS). All students performed restorations in primary teeth with the majority providing approximal restorations (91%), pit and fissure restorations (89%) followed by stainless steel crowns (81%). In addition, all students performed a pulpotomy for a primary tooth, extraction of a primary tooth and fissure sealants. Only a quarter of the students treated a traumatised incisor. Students considered themselves most confident (VAS ≥ 7) in performing operative dentistry, examination, diagnosis and treatment planning and providing preventive therapy. They were least confident in the management of dento-alveolar trauma (VAS = 3.8). Students at the University of Jordan Dental School were found to have good experience of clinical paediatric operative dentistry with the majority performing pulp therapy, preformed crowns and extractions. Deficiencies have been reported in student exposure to dental trauma, and these are being addressed. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To compare dental implant survival rates when placed in native bone and grafted sites. Additionally, risk factors associated with dental implant loss were identified. This study was based on the hypothesis that bone grafting has no effect on implant survival rates. A retrospective chart review was conducted for patients receiving dental implants at the University of Texas, School of Dentistry from 1985 to 2012. Exclusion criteria included patients with genetic diseases, radiation and chemotherapy, or an age less than 18 years. To avoid misclassification bias, implants were excluded if bone grafts were only done at the same time of placement. Data on age, sex, tobacco use, diabetes, osteoporosis, anatomical location of the implant, implant length and width, bone graft, and professional maintenance were collected for analysis. A total of 1,222 patients with 2,729 implants were included. The cumulative survival rates at 5 and 10 years were 92% and 87% for implants placed in native bone and 90% and 79% for implants placed in grafted bone, respectively. The results from multivariate analysis (Cox regression) indicated no significant difference in survival between the two groups; having maintenance therapy after implant placement reduced the failure rate by 80% (P dental implant survival rate when implants were placed in native bone or bone-grafted sites. Smoking and lack of professional maintenance were significantly related to increased implant loss.

Molar-Incisor Hypomineralization (MIH) is a condition of hypomineralized enamel of systemic origin affecting first permanent molars and frequently permanent incisors. It is considered a global problem and data from South-East Asian countries, including Malaysia are lacking. Hence the aim of this study were to investigate the distribution and severity of MIH in a group of children aged 7-12 year olds attending pediatric dental clinic at Faculty of Dentistry, Universiti Teknologi MARA (UiTM), Malaysia. Hundred and fifty four children age 7-12 year-old with mean age of 9.14 ±1.682 had their first permanent molars and permanent incisors were examined at Faculty of Dentistry, UiTM using European Academy of Paediatric Dentistry 2003 (EAPD) criteria for diagnosis of MIH. Children at least one first permanent molar affected were considered as having MIH. Data were recorded and statistically analysed using descriptive analysis and Chi square test. Twenty six of the total examined children (n=154) had MIH (16.9%). There was no statistical difference between males and females in the prevalence of MIH. However, a statistical significant difference was found by age groups. The first permanent molars were more frequently affected (58%) as compared to permanent incisors. Mandibular molars were to have the highest rate of MIH (15.5%). The right and left sides were equally affected. Mild defects were the most frequent lesion type (96.6%). This study revealed that MIH is a common condition (16.9%). Molars were more frequently affected than incisors with mild defects were the most common lesion status. Further studies on this defect amongst Malaysian children are worthwhile.

Good management/administration is vital in the realisation of any business objective whether in a private or public establishment. The aims of this study were to assess the level of knowledge and ability on management/administrative skills by Medical/Dental consultants as perceived by themselves; to stimulate more interest in management/administrative skills acquisition, and to suggest possible ways in achieving such skills by doctors. A self-evaluation questionnaire was distributed to the doctors and 88 of them completed and returned their forms. They consisted of 55 (62.5%) males and 33 (37.5%) females cutting across all the specialities in medicine and dentistry in the University College Hospital, Ibadan, Nigeria. In all, 42 (47.7%) of the respondents reported that they had good ability of management/administration while 46 (52.3%) were below average. Of the 55 males, 28 (31.8%) had good ability while 27 (30.7%) were below average. Fourteen (15.9%) of the females had good ability while (21.6%) were below average. Good knowledge was assumed by 41 (46.6%) of the respondents while 47 (53.4%) were below average. Twenty-seven (30.7%) of the males showed good knowledge as against 14 (15.9%) of the females. Twenty-eight (31.8%) of the males were below average as against 19 (21.6%) of the female respondents. The sex differences were not statistically significant (P>0.05). The surgeons significantly (Pskills than physicians though their claim of ability to perform was higher too but significant (P>0.05). The percentage of the consultants with good knowledge and ability was found to increase with increasing age except for those under 40 years of age. The differences were not significant (P>0.05). A strong positive correlation (r=0.948; Pskills will positively affect their performance abilities.

Materials and Methods: A cross-sectional study was conducted amongst a total of 178 postgraduate students which includes 112 medical and 66 dental disciplines of Medical University in Western Maharashtra during the period of June-August 2013. Data was analyzed in the form of percentage and proportions and Chi-square test was applied whenever necessary. Results: In the present study, 42.1% students didn′t know the concept of ′autonomy′ in palliative care, while 107 (60.1% of students believed that most preferable route of administration in palliative care for treating chronic cases is oral. Among medical students 41.6% had shown overall good level of knowledge, while only 16.6% of dental students showed overall good level of knowledge. There was a significant difference found in the level of knowledge among the postgraduates between two disciplines. Conclusion: The study revealed the inadequacy in knowledge amongst postgraduate students of both disciplines; however knowledge level of dental was poor as compared to medical students. There is need to introduce palliative care in postgraduate curriculum of all health professional education.

The aim of this study was to evaluate the long-term adoption of a risk-based caries management program at a university dental clinic. The authors extracted data from electronic records of adult non-edentulous patients who underwent a comprehensive oral evaluation in the university predoctoral clinic from July 2007 through June 2014 (N=21,984). Consistency with caries management guidelines was measured as the percentage of patients with caries risk designation (low, moderate, high, or extreme) and the percentage of patients provided non-operative anti-caries agents within each designated caries risk category. Additionally, patient and provider characteristics associated with risk assessment completion and with provision of anti-caries therapy were identified. Results showed that the percentage of patients with documented caries risk grew steadily from 62.3% in 2007-08 to 92.8% in 2013-14. Overall, receipt of non-operative anti-caries agents increased with rising caries risk, from low (6.9%), moderate (14.1%), high (36.4%), to extreme (51.4%), but percentages were stable over the study period. Younger patients were more likely to have a completed risk assessment, and among high- and extreme-risk patients, delivery of anti-caries therapy was more common among patients who were younger, identified as Asian or Caucasian, received public dental benefits, or were seen by a student in the four-year DDS program or in the final year of training. These results demonstrate that extensive compliance in documenting caries risk was achieved within a decade of implementing risk-based clinical guidelines at this dental school clinic. Caries risk was the most strongly associated of several factors related to delivery of non-operative therapy. The eventual success of this program suggests that, in dental education, transition to a risk-based, prevention-focused curriculum may require a long-term commitment.

As a profession, dentistry is at a point of discernible challenge as well as incredible opportunity in a landscape of evolving changes to health care, higher education, and evidence-based decision making. Respecting the past yet driving forward, a well-mapped future course is critical. Orchestrating this course in a collaborative manner is essential for the visibility, well-being, and potentially the existence of the dental profession. The research performed in dental institutions needs to be contemporary, aligned with biomedical science in general, and united with other disciplines. Dentistry is at risk of attrition in the quality of its research and discovery mission if participation with bioscience colleagues in the collaborative generation of new knowledge is underoptimized. A fundamental opportunity dentistry has is to contribute via its position in academic health centers. Rigorous research as to the impact of interprofessional education and collaborative care on population health outcomes provides significant potential for the dental profession to participate and/or lead such evidence-centered efforts. It is imperative that academic dental institutions are part of interdisciplinary and transdisciplinary organizations that move health care into its new day. Strategizing diversity by bringing together people who have different ways of seeing problems to share perspectives, heuristics, interpretations, technologies, and predictive models across disciplines will lead to impactful progress. Academic dental institutions are a natural part of an emphasis on translational research and acceleration of implementing new scientific discoveries. Dentistry needs to remain an essential and integrated component of higher education in the health professions; doing so necessitates deliberate, respectful, and committed change. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

The purpose of this survey was to examine the overview of maxillofacial prosthetic treatment at our department, in order to ascertain the actual status of patients and discuss future needs. Subjects were all patients who visited Clinic for Maxillofacial Prosthetics, Dental Hospital, Tokyo Medical and Dental University (TMDU) in the period from January 1, 1980 to December 31, 2014. Using medical records of the Clinic for Maxillofacial Prosthetics, Dental Hospital, TMDU, patients' data including sex, address, referring institution, and primary condition were analyzed throughout the period. The number of patients over 35 years was 6219, with a man-to-woman ratio of 6:4. The number of patients in their 60s, 70s, and 80s showed an increasing trend. Patients with tumors accounted for about 50 % of cases in 1980-1984 and increased to 80 % in 2010-2014. The survey showed an increasing number of elderly patients and patients with tumors. This suggests that more awareness and education about maxillofacial prosthetics are needed. Copyright © 2018 Japan Prosthodontic Society. Published by Elsevier Ltd. All rights reserved.

To assess the awareness, attitude, and knowledge about basic life support (BLS) among medical, dental, and nursing students and faculties and the proposal of BLS skills in the academic curriculum of undergraduate (UG) course. Recognition, prevention, and effective management of life-threatening emergencies are the responsibility of health-care professionals. These situations can be successfully managed by proper knowledge and training of the BLS skills. These life-saving maneuvers can be given through the structured resuscitation programs, which are lacking in the academic curriculum. A questionnaire study consisting of 20 questions was conducted among 659 participants in the Kalinga Institute of Dental Sciences, Kalinga Institute of Medical Sciences, KIIT University. Medical junior residents, BDS faculties, interns, nursing faculties, and 3 rd -year and final-year UG students from both medical and dental colleges were chosen. The statistical analysis was carried out using SPSS software version 20.0 (Armonk, NY:IBM Corp). After collecting the data, the values were statistically analyzed and tabulated. Statistical analysis was performed using Mann-Whitney U-test. The results with P < 0.05 were considered statistically significant. Our participants were aware of BLS, showed positive attitude toward it, whereas the knowledge about BLS was lacking, with the statistically significant P value. By introducing BLS regularly in the academic curriculum and by routine hands on workshops, all the health-care providers should be well versed with the BLS skills for effectively managing the life-threatening emergencies.

Background Oral implant rehabilitation should be considered a treatment option for any edentulous patient and Implant Dentistry is currently a discipline taught in the undergraduate formation. The level of knowledge acquired and how the students perceive the quality of training in Implant Dentistry could assess to know if it is necessary to improve the syllabus. Material and Methods A questionnaire was developed with 11 questions: Basic knowledge (7); Perception of training received (2); Ways in which students would receive training (2). To be responded anonymously and voluntarily for undergraduates students in the Faculty of Dentistry (University of Barcelona, Spain). Results One hundred and seven students, 76 third year (Group A) and 31 fourth year (Group B) answered the questionnaire. In Group A, 98.68% of students and in Group B 93.54% believed they were poorly informed; 100% of both groups would prefer to receive more training as part of the degree or as postgraduate training through modular courses imparted by experts (A: 71,05%, B: 70,96%) Training through postgraduate programs or training given by private businesses were the least desirable options (A: 42%, B: 64.51%). Questions about basic knowledge acquired received varying responses, which might indicate a certain level of confusion in this area. Conclusions The undergraduate syllabus must be revised to include sufficient content and training to allow the student to indicate implant-based treatments based on evidence. Students would prefer training to be included in the undergraduate syllabus. Key words:Dental implants, dental students, dental education, dental syllabus, implant dentistry. PMID:28578375

Full Text Available A significant number of children visit a dentist for the first time due to emergency situations. However, little is known regarding the prevalence, etiology, and treatment provided for children at emergency dental visits. This study aimed to evaluate the profile of children attending a dental school emergency clinic, the reasons for seeking dental care, and the treatment provided. Records of 270 patients who attended an emergency clinic during 2010 were analyzed, and 253 were selected. Demographic, diagnostic, and procedural information was collected. The mean child age was 7.8 years. For 208 children (82%, pain was the main reason for the emergency visit. Nearly 79% of the visits were due to caries, and the most frequently required treatment was endodontic intervention (31.22%. Of the decayed teeth, 61.70% were primary posterior teeth and 31.9% permanent posterior teeth. Pain caused by dental decay was the most frequent chief complaint. A large number of children were brought to the dentist with complaints that had started long before, for which over-the-counter medications had been used.

The purpose of this study was to determine the risk of dental caries in relation to oral hygiene habits and food intake among women at university in Saudi Arabia. A sample of 935 undergraduate university women was selected from the King Abdulaziz University in Jeddah, Saudi Arabia. A previously pretested questionnaire was used to collect the data. Odds ratios were calculated to estimate the risk of dental caries associated with oral hygiene and food intake. The findings revealed that women who cleaned their teeth three times or more per day mostly cleaned their teeth after intake of sweets and chocolates, and had no gingivitis were at less risk of dental caries than other women (p=0.029, p=0.000 and p=0.000, respectively). The intake of milk, fruit and vegetables on 4 days or more per week was found to protect against dental caries (odds ratios=0.34, 0.64 and 0.73, respectively), whereas the intake of chocolate and soft drinks for the same period was found to be a risk factor for dental caries (odds ratios=1.8 and 1.4, respectively). The results of this study are useful for public health intervention programs to combat dental caries in the Saudi community.

There is a substantial body of evidence of income-related inequalities in dental care use, attributed to the fact that dental care is often not covered by public health insurance. Wealth-related inequalities have also been shown to be greater than income-related inequalities. Japan is one of the exceptions, as the the universal pubic health insurance system has covered dental care. The aim of this study was therefore to compare wealth- and income-related inequalities in dental care use among middle-aged and older adults in Japan to infer the mechanisms of wealth-related inequalities in dental care use. Data were derived from the Japanese Study of Aging and Retirement, a survey of community-dwelling middle-aged and older adults living in five municipalities in eastern Japan. Of the participants in the second wave conducted in 2009, we analyzed 2581 residents. Dental care use was measured according to whether the participant had been seen by a dentist or a dental hygienist in the past year. The main explanatory variables were income and wealth (financial assets, real assets and total wealth). The need for dental care was measured using age, the use of dentures and chewing ability. The concentration indices for the distribution of actual and need-standardized dental care use were calculated. Among the respondents, 47.9% had received dental care in the past year. The concentration index of actual dental care use (CI) showed a pro-rich inequality for both income and wealth. The CIs for all three wealth measures were larger than that for income. A broadly comparable pattern was seen after need-standardization (income: 0.020, financial assets: 0.035, real assets: 0.047, total wealth: 0.050). The results showed that wealth-related inequalities in dental care use were greater than income-related inequalities in Japan, where most dental care is covered by the public health insurance system. This suggests that wealth-related inequalities in dental care use cannot be explained

As dental professionals, we continue to learn ethical lessons throughout our careers and beyond. We may experience them in our day-to-day involvements with peers and patients, or they may present themselves under more unusual circumstances. In October, 1974, at the University of Madrid Dental School, the senior author had a deeply impressionable experience minutes before he helped to present a course to Spanish dentists in operative dentistry. His co-presenter was Dr. Miles R. Markley of Denver, Colorado, a National Consultant in Restorative Dentistry for the U.S. Air Force. Their ethics teacher that day was Dr. Gerardo Zabalo, Dean of the dental school. His object lesson was delivered at the base of an equestrian, aluminum, larger-than-life sculpture, "The Torch Bearers" which faced the school. The sculptor shows an old, wrinkled man, lying prostrate, with only enough strength left to raise a lighted torch upward. Reaching down to receive the torch is a robust, energized young man, who is sitting upon a sturdy stallion. The lesson which Dean Zabalo taught that day was simple but profound. The lit torch of ethics, learning and values is essentially transmitted from generation to generation, as young students learn from their elders, accept the torch from their retiring leaders, keep the torch brightly lit as they mature in their profession, and, then in turn, hand it over to those young professionals who will replace them. This process will continue, age after age. Thus the torch of learning and thinking is passed on. In the world of education, human contact and the continued sanctity of the scientific written word must be paramount. Students must be taught how to read, learn and think. Computer technology used exclusively as a mode of teaching and learning can never become a viable substitute for our traditional interactive methods which emphasize human to human interaction.

The curriculum of the dental faculty at the University of Bergen, Norway, was revised and a new curriculum implemented in 1998 based on the principles of holistic teaching and patient-centered treatment. The first candidates graduated in 2003. The change of curricula, experience gained, and lack of an evidence base for holistic teaching justify a general discussion of all relevant aspects associated with this approach. The purpose of this article was to make a contribution towards such a discussion. A PubMed search regarding holistic teaching in dentistry was performed. Of the 211 entries on holistic teaching, few discussed holism in depth; none reported outcome measures comparing old and new curricula. Data collected from students graduating in 2003 (new curriculum) and 2000 (old curriculum) on their satisfaction with the teaching comprise a possible outcome measure. In most respects, using prosthodontics as an example, no differences between the two groups of students were found. Students studying under the new holistic curriculum were less satisfied than those studying under the old one regarding the number of available teachers and teachers' feedback on student performance. Both holistic teaching/patient-centered treatment and a more traditional subject-specific approach have advantages and disadvantages, and neither can be practiced in its pure form for ethical and practical reasons. The quantitative results of this study did not support the hypothesis that holism improved students' satisfaction with the teaching. A wide discussion of holism in dental education is needed, along with outcome measures when curricula are changed.

A live broadcasting system was developed as part of dental education with Information and Communication Technology (ICT) at Tokyo Medical and Dental University. The purpose of this study was to utilize this system in complete denture prosthodontics, especially for the procedure of making a definitive impression with custom tray border molding in edentulous patients, and to evaluate its effectiveness. Live broadcast lectures on complete denture prosthodontics were given to fourth-year students in 2009 (fifty-nine students) and in 2010 (sixty-five students). To evaluate this lecture, a questionnaire was distributed to the students and faculty members after the lecture. Almost all the students and faculty members rated the lecture as good. Students commented that the lecture was "intelligible," "inspiring," "improved understanding," "good because they could ask questions in real time," "helped to know the actual time," "good for all the students to see the same case," and "close to real experience and induced a sense of tension." The results of this study suggested that a live broadcast lecture would help students experience the real clinical situation and aid in teaching complete denture prosthodontics.

Medication-related osteonecrosis of the jaws (MRONJ) is a well-established complication of anti-resorptive and, more recently, anti-angiogenic therapy. The dental profession has a pivotal role to play in the prevention and management of this debilitating condition, and all dentists have a responsibility to remain cognisant of national and international best practice guidelines in the prevention of this disease process. The management of patients in the Dublin Dental University Hospital at risk of MRONJ when carrying out dental interventions was audited against nationally- and internationally-published guidelines. The results of the audit showed compliance with the national and international guidance in 5% and 0% of cases, respectively. The most common measures implemented in the management of patients at risk of MRONJ were: preoperative antibiotics in 49% of cases; preoperative chlorhexidine mouthwash in 76%; plain local anaesthetic in 51%; and, post-operative antibiotics in 80%.

To develop and test the psychometric characteristics of a questionnaire that measures attitudes towards e-learning, as well as to study attitudes about e-learning and to identify variables related to those attitudes amongst dental students. The study was conducted from November 2010 to December 2011 at all three Croatian dental schools. A questionnaire entitled 'Attitude Towards e-Learning' consisting of 12 questions about socio-demographic data and 22 statements about attitude towards e-learning was self-administered by 386 students. Factorial analysis and Cronbach's alpha were used to test the psychometric characteristics of the questionnaire. Multiple regression analysis was used to identify variables related to attitudes towards e-learning. Factorial analysis confirmed two factors: positive attitude and negative attitude, which interpret 58% of the total variance and had good internal consistency of α = 0.852 and 0.668, respectively. The average score of positive attitude was 42 ± 6, indicating a highly positive attitude towards e-learning. The average score of negative attitude was 27 ± 6, indicating minor negative attitude. Higher age and study year, usage of the Internet in education, more frequent usage of Facebook and more attendance of e-courses demonstrated a significant influence on positive attitude towards e-learning (R(2) = 0.304; P attitude (R(2) = 0.268; P attitudes towards e-learning. Teachers should adopt strategies to change negative attitudes by introducing more e-learning courses in lower study years and should encourage students to use the Internet in their education and communication with teachers and colleagues. © 2013 John Wiley & Sons A/S.

Inappropriate use of antibiotics may lead to adverse side effects. This cross-sectional survey aimed to investigate the knowledge and attitude of female non-medical students regarding the medical and dental use of antibiotics. Four hundred validated self-administered questionnaires were distributed in Princess Norah Bint-Abdurrahman University, Riyadh, Saudi Arabia. The questionnaire included questions about accessibility, attitude toward usage, efficacy, side effects, resistance, and usage for dental issues. Knowledge was estimated for every respondent by counting the correct answers, which were considered as points. The scores were categorized as poor, moderate, and high. Of the respondents, 77.8% answered they get antibiotics according to a doctor's prescription; however, 31% stops taking antibiotics when they feel well. Only 38.8% of respondents knew that antibiotics may cause allergic reactions while 59.8% believed the human body can be resistant to antibiotics. The percentages of answers related to dental issues were: antibiotics relieve dental pain (68.8%), antibiotics can be harmful for children's teeth (27.3%), antibiotics are best avoided in pregnancy (56.7%) and no need for antibiotics after scaling (33.8%), root canal treatment (16%), or simple extraction (40.3%). Of respondents, 68% had poor scores about antibiotics efficacy, side effects, and resistance while 86.8% had poor scores related to dental problems. This study noticed a bad attitude related to antibiotics usage, with many misconceptions and poor knowledge. Moreover, the necessity of antibiotics for treatment of dental disease or after dental procedures was totally unclear for the respondents. Community campaigns are recommended every university semester to educate students about the indications, efficacy, and side effects of antibiotics. Copyright © 2017 The Authors.

As dental education across the United States undergoes growth and change in an effort to improve access to dental care, one dental school, the Arizona School of Dentistry & Oral Health, established in 2003, designed its initial curriculum with innovation in mind. One of those innovations was the introduction of an online certificate in public health that can be used as the foundation for a Master's in Public Health (M.P.H.) degree with a dental emphasis, which students may complete concurrent with their dental education. This article discusses the educational intersection between dentistry and public health and describes how this dental school uses an online public health curriculum to accomplish this integration. It also presents the potential advantages and disadvantages of obtaining the M.P.H. degree concurrent with the dental school training.

The authors argue that dental curricula in Latin America are noted for providing highly technical and individualistic training that may fail to address society's problems or instil in the dentist the idea that he/she has a social responsibility to contribute to his/her community. This study's main objectives were to determine whether the curriculum and the faculty teaching practices of the School of Dentistry at the University of Chile contribute to its students' commitment to ethical and social responsibility. This was a qualitative study that investigated the perceptions of sixteen subjects (eight students and eight faculty members). Data were collected in thorough deep interviews. The interview process model conceptualised and organised the information into sets of dimensions and categories. The dimensions studied were ethical commitment and social responsibility. The categories assessed within ethical commitment were honesty, tolerance, responsibility and respect. In the social responsibility dimension, the categories were solidarity, teamwork and concern for and communication with the patient. Analysis of the textual data was performed using a method of content analysis based upon constructed qualitative matrices. Our results show that students and scholars alike realise that ethical commitment and a sense of social responsibility are not promoted in the curriculum. They do, however, recognise the importance of these qualities in dental practitioners. These results indicate that the current curriculum and teaching practices used in our School of Dentistry need to be reviewed and that programmes promoting professionals' commitment to their role in society need to be implemented. © 2012 John Wiley & Sons A/S.

To assess the prevalence and level of dental fear among health related undergraduates and to identify factors causing such fear using Kleinknecht's Dental Fear Survey (DFS) questionnaire. Kleinknecht's DFS questionnaire was used to assess dental fear and anxiety among the entire enrollment of the medical and dental undergraduates' of the University of Malaya. Overall response rate was 82.2%. Dental students reported higher prevalence of dental fear (96.0% versus 90.4%). However, most of the fear encountered among dental students was in the low fear category as compared to their medical counterpart (69.2 versus 51.2%). Significantly more medical students cancelled dental appointment due to fear compared to dental students (P = 0.004). "Heart beats faster" and "muscle being tensed" were the top two physiological responses experienced by the respondents. "Drill" and "anesthetic needle" were the most fear provoking objects among respondents of both faculties. Dental fear and anxiety are a common problem encountered among medical and dental undergraduates who represent future health care professionals. Also, high level of dental fear and anxiety leads to the avoidance of the dental services.

Diabetes mellitus and hypertension are the leading chronic diseases in Saudi Arabia; 23.1% of the Saudi population are diabetic and 25.5% are hypertensive. This cross-sectional study was made on dental setting to determine the effectiveness of screening of diabetes and hypertension in dental clinics. This study was carried out in the primary care dental clinics at the Dental College in King Saud University in Riyadh, Saudi Arabia. Before starting any treatment, a face-to-face interview was administered to collect a brief medical history and personal data followed by measurement of body mass index (BMI). After that, blood pressure level reading was obtained using electrical sphygmomanometer. Finally, a glucose level reading was obtained from capillary blood from the patient's third fingertip using glucose reader. Our study included 283 participants, 118 of whom were females (41.7%). Our study showed that a significant amount of the participants are at risk of having hypertension (44.8%). In addition, a significant number (10.2%) of the participants are at risk of having diabetes. Furthermore, 35.7% of the sample had obesity as a risk factor for diabetes and hypertension. The dental team can play an important role in screening of diabetes, hypertension, and other chronic diseases. In Saudi Arabia, public awareness of the chronic diseases is still critically insufficient. Our study showed the importance of the screening even for patients with negative history of diabetes or hypertension.

In Japan, the increasing frequency of mental health problems in postgraduate dental trainees has recently become apparent. To our knowledge, there has been no previous research to investigate the influence of the type of training program on the mental health of dental residents during one year of postgraduate clinical training. Therefore, the purpose of this study was to compare changes in the mental health of two groups of dental trainees at Kyushu University Hospital, Fukuoka, Japan: those who undertook a rotation training program and those who trained solely in one department (the control group). Study subjects in both groups completed the Profile of Mood States (POMS) and the General Health Questionnaire (GHQ) at five intervals throughout the postgraduate training year. Analysis of the questionnaire responses were performed by Student's t-test, analysis of variance, Bonferroni's test, and the chi-square test. Statistical tests showed differences in the mean scores of POMS-30 subscales and GHQ-28. The mood of anger was the factor that seemed to best describe the trainees' response to stress. The study results led to the conclusion that dental trainees' mental health is influenced by the type of training program and that dental trainees in rotation training programs may need more mental health support.

To assess the knowledge about hepatitis B among the medical, dental and nursing students of first year in Subharti University, a private medical university of North India. A cross sectional institutional study was conducted among the first year students of medical, dental and nursing colleges of Subharti University. The total subjects studied were 250. Data was collected when the student came up for hepatitis B vaccination in the Department of Community Medicine. Data was entered in MS Excel and analyzed using Epi Info for Windows. Bivariate analysis using Chi-square test was applied. Overall, 83.32% of the study subjects had heard of hepatitis B. Only 42% knew that virus is a cause of hepatitis B. Awareness of mother to child transmission of hepatitis B was present in only 12% of the study subjects. Unsafe blood transfusion as a risk factor of hepatitis B was known by 35.2%, whereas, prevalence of knowledge regarding reused needles and unsafe sex as risk factors was lesser. Forty-four percent of the study subjects were not aware of vaccination against hepatitis B. There was a significant difference in the proportion of students of the different faculties about the correct knowledge about hepatitis B. The knowledge about hepatitis B was very low among the students entering in the medical, dental and nursing profession. This highlights the importance of informed and evidence based education programmes among the students of these healthcare professions.

Nova Southeastern University College of Dental Medicine (NSU-CDM) has developed a program to educate its Advanced Education in General Dentistry (AEGD) residents to provide oral health services to survivors of domestic violence. NSU-CDM worked in collaboration with three community-based sites in Florida's Dade and Broward counties that provide residential and outpatient services to women survivors of domestic violence. The educational program includes didactic instruction and clinical rotations utilizing portable dental equipment assembled at the community-based sites. The central element of the program was the establishment of a partnership between NSU-CDM and local community-based organizations that serve women who have experienced domestic violence. This collaboration enabled the school to involve a range of key stakeholders in program development and implementation and to successfully establish dental clinics at two shelter sites. In total, NSU-CDM provided dental care to over 250 women, and twenty AEGD residents completed both the didactic and clinical rotations of the domestic violence education program. Elements identified as being essential to successful collaborations between oral health clinics and shelter settings are described.

Full Text Available Abstract Background More than 1 million individuals in the U.S. are infected with HIV; approximately 20% of whom do not know they are infected. Early diagnosis of HIV infection results in earlier access to treatment and reductions in HIV transmission. In 2006, the CDC recommended that health care providers offer routine HIV screening to all adolescent and adult patients, regardless of community seroprevalence or patient lifestyle. Dental providers are uniquely positioned to implement these recommendations using rapid oral fluid HIV screening technology. However, thus far, uptake into dental practice has been very limited. Methods The study utilized a qualitative descriptive approach with convenience samples of dental faculty and students. Six in-depth one-on-one interviews were conducted with dental faculty and three focus groups were conducted with fifteen dental students. Results Results were fairly consistent and indicated relatively high levels of acceptability. Barriers and facilitators of oral fluid HIV screening were identified in four primary areas: scope of practice/practice enhancement, skills/knowledge/training, patient service/patient reactions and logistical issues. Conclusions Oral fluid HIV screening was described as having benefits for patients, dental practitioners and the public good. Many of the barriers to implementation that were identified in the study could be addressed through training and interdisciplinary collaborations.

Full Text Available The efficacy of methods like e-learning as a supplement to traditional face-to-face instruction needs to be evaluated in dental courses. This study aimed to assess the efficacy of posting case presentations on one of the educational websites of the virtual school of Tehran University of Medical Sciences called “SARMAD” to enhance the ability of senior dental students to diagnose tooth discolorations and offer treatment plans. This experimental study had a pre-test/post-test control group design and was conducted on 63 senior dental students. After filling out the primary questionnaire and obtaining a written informed consent, students participated in a pre-test and were then randomly divided into two groups of intervention and control. Fifteen case presentations were posted on the university website (SARMAD during 6 weeks and discussed. Then, students participated in a post-test. Students’ perspectives and their satisfaction with the website were assessed by a questionnaire. For ethical purposes, the same program was also offered to the controls. The post-test score was significantly higher than the pre-test score in the intervention group (P<0.001; but in the control group, the post-test score was only slightly higher than the pre-test score (P=0.128. In the intervention group, 70% stated that they would suggest this method as an efficient educational modality; 93.3% stated that this method would be beneficial as a supplement to conventional education; 16.7% ranked the SARMAD website excellent, 30% ranked it good, 33.3% acceptable, 16.7% moderate and 3.3 poor. It appears that this instructional modality may be efficiently used as a supplement to traditional instruction in undergraduate dental curricula.

Full Text Available Anxiety is a psychological and physiological condition which signed by emotion, cognitive, and someone’s behavioral component. Anxiety behavior has long been recognized as the most difficult aspect in the management of patients and may frustrate a dental treatment that will be carried out, especially in children ages 6-12 years. Fear of treatment tooth extraction and local anesthesia is the main reason for kids disliking dental care. This type of research is observational analytic with nonprobability sampling technique, because this study used a population of pediatric patients who visited the location of the research that has been determined. Total sample of this research are 30 people who fulfill the criteria. The sample consist of 16 boys and 14 girls with age range of 6 to 12 years old. The level of anxiety before and after tooth extraction assessed using Facial Image Scale (FIS. Facial Image Scale (FIS has five criteria which describe the level of anxiety in children, very happy by point 1, happy by point 2, normal by point 3, unhappy by point 4, and very unhappy by point 5. The results of the analysis of differences in anxiety with FIS measurement tools show there are differences in the level of anxiety in children before and after tooth loss based on the location of the jaw, the type of anesthesia applied topically, gender, and overall. Overall, there is a difference in children before and after tooth loss and the difference is significant

In order to improve the prevention and treatment of dental caries in Burkina Faso, we conducted a study on the epidemiological and therapeutic aspects of dental caries in the dental services of University Teaching Hospital Yalgado Ouedraogo and in the Municipal Centre of Oral Health of Ouagadougou. A prospective and descriptive study from October, 15th 2012 to January, 15th 2013 was conducted on a sample of 191 patients. The variables recorded were: patient's identity, age, sex, area of residence, food mode, socioeconomic level, reason for consultation, oral hygiene, DMFT index, degree of tissue damage, the topography of the carious lesions and the applied therapy. Caries prevalence was 93.19% more female consultations, with sex ratio at 0.77. The average age was 31 years for a sample often engaged in trade and the informal sector. Carious lesions were usually limited to less than 4 teeth. The main motivation for the consultation was pain at 82.20%. The use of preventive care is quite low in our population. Extractions still occupy an important part of treatment. We need to improve oral hygiene and show to patients the necessity of routine visits to the dentist every year for early treatment.

Picture archiving and communication system (PACS) is an image information technology system for the transmission and storage of medical images. In Korea the first full PACS was installed at Samsung Medical Center in 1994, but, the rate of distribution was very slow. The government's approval for the medical insurance reimbursement for full PACS examinations in November 1999 became the turning point. Thereafter the number of hospitals with full PACS has steeply increased. In September of this year, PACS was installed at 906 medical institutes, including most of university hospitals and general hospitals. The first full dental PACS was installed at Wonkwang University Dental Hospital in 2002. Now ten out of eleven university dental hospitals implemented full dental PACS. The current status and technological factors of dental PACS in Korean university dental hospitals and the future perspectives of dental PACS are described.

Full Text Available Background and Aims: Iatrogenic damage to adjacent tooth during proximal cavity preparation is one of the most common side effects in operative dentistry. The aim of this study was to determine prevalence of iatrogenic damages to adjacent tooth during the preparation of proximal Class II cavities among undergraduate students at dental faculty of Tehran University of Medical Sciences in 2010 . Materials and Methods: 106 posterior permanent teeth which had Class II decay with sound proximal surfaces of adjacent teeth were selected and restored by dental students awarding the aims of the present study. After finishing restoration, proximal surfaces were completely dried by air and evaluated with dental chair light. In doubtful cases, surfaces were evaluated with × 3 magnification. Damages were classified into 2 groups; abrasion and groove. Data were analyzed using Fishers exact and Pearson chi square tests . Results: The frequency of adjacent surfaces damage were 57.5%, with 31.1% damages as abrasion and 26.4% as groove. Students who used matrix band and wedge in proximal area as preventive instruments showed 53.4% damages and other students showed 57.3% damages (P>0.05. A significantly higher number of females and students at restorative course level (3 used wedge and matrix band than males and students at restorative course level (4 for protecting adjacent teeth (P<0.05. Conclusion: According to the high percentage of iatrogenic damages on adjacent sound teeth in class II cavity preparation, teaching of preventive methods and using proper techniques is necessary for dental students as future dentists.

To evaluate radiographically the quality of root canal fillings and compare manual and rotary preparation performed on extracted teeth by undergraduate dental students. A total of 561 premolars and molars extracted teeth were prepared using nickel-titanium rotary files or manual instrumentation and filled with gutta-percha using a cold lateral condensation technique, by 4th grade undergraduate students. Periapical radiographs were used to assess the technical quality of the root canal filling, evaluating three variables: length, density and taper. These data were recorded, scored and used to study the "technical success rate" and the "overall score". The length of each root canal filling was classified as acceptable, short and overfilled, based on their relationship with the radiographic apex. Density and taper of filling were evaluated based on the presence of voids and the uniform tapering of the filling, respectively. Statistical analysis was used to evaluate the quality of root canal treatment, considering p < 0.05 as a statistical significant level. The percentage of technical success was 44% and the overall score was 7.8 out of 10. Technical success and overall score were greater with rotary instruments (52% against 28% with a manual one, p < 0.001; 8.3 against 6.7 respectively, p < 0.001). It appears that inexperienced operators perform better root canal treatment (RCT) with the use of rotary instrumentation.
This study aimed to describe the development and evaluation of an outreach dental public health (DPH) programme in Damascus University, in terms of developing undergraduates' required knowledge, skills and attitudes (KSA), improving the quality aspects of training and assessment (T&A), and achieving the satisfaction of served children and their social network. The outreach DPH programme offered opportunities to undergraduates to carry out outreach health-promotion activities, conduct and communicate the results of applied DPH research, and build partnership with students in other higher education sectors. A cross-sectional evaluation collected mixed qualitative and quantitative data, by a means of a short-essay and a self-completed questionnaire, from 400 third-year dental undergraduates, on KSA gained from outreach activities and quality aspects of T&A. The latter were compared with corresponding figures of other traditional dental programmes (TDP). Satisfaction with the outreach activities were collected from 215 children with special needs and 130 parents and school staff, by questionnaires. The response rates were 74.8%, 100% and 100% for undergraduates, children and parents/school staff, respectively. The derived categories of students' gained KSA included the following: unique clinical skills, social responsibility, voluntarism, communication, team working, personal growth, reflection on career aspirations and self-satisfaction with the contribution to needy groups. Their satisfaction with quality aspects of T&A was significantly higher than TDP (P < 0.001). Children's and parents/school staff's satisfaction was high. The outreach DPH programme in Damascus University is a successful example of developing undergraduates' required KSA, improving the quality aspects of T&A, and achieving the satisfaction of served community. © 2015 John Wiley & Sons A/S.

A study is made of the experience gained with the Child Oral Care Program (Plan de Atención Dental Infantil, PADI) in the Service of Stomatology of Valencia University General Hospital (Valencia, Spain) after four years in operation (July 2003 - July 2007). The sample comprised 2626 children between 5-14 years of age, pertaining to department 9 of the Valencian public health system. A clinical history was compiled in each case, a radiological study was made, and a treatment plan was elaborated including fillings, extractions, and control visits. Of the 2626 designated children, 2369 visited our Service - mostly referred from the Preventive Dental Care Units. A total of 5784 fillings were carried out (93.3% with silver amalgam, 5.6% with composites and the rest as provisional fillings). The permanent first molars were the teeth with the largest number of fillings (70.2% of the total). These were followed in order of frequency by the second molars (19.1%). As regards composite resin fillings, most involved the upper central incisors, followed by the upper lateral incisors. A total of 644 extractions were performed, corresponding to 110 permanent teeth and 534 temporary teeth. In the case of the permanent dentition, the first molars were the most commonly removed teeth. In the temporary dentition, the most frequently removed teeth were the second molars. The response of the population to this program has been very good, and reinforces the preventive measures already in place, with the provision of restorative treatments to improve the oral and dental health of the pediatric population, and yielding good results in terms of the program quality indicators. The Service of Stomatology (Valencia University General Hospital) is able to address the demand and offers the public health network integrated and continuous patient care.
Full Text Available ICDAS (the International Caries Detection and Assessment System is a new approach to the detection and classification of dental caries, starting with the stage showing the earliest visual changes. Methodology: This article describes the implementation of the ICDAS at the School of Dentistry, International Medical University, and Kuala Lumpur, Malaysia in a step-by-step systematically planned process. Beginning with the setting up of a Task Force in 2011 for the evaluation and preparation of the training resources and the running of exploratory training exercises, it finally culminated in carrying out training workshops for the entire staff and students. After the internal processes had been completed, an international expert (KE was invited to evaluate the process and conduct another workshop using the resources developed within the University, including a reference set of carious teeth. The overall time taken was one and a half years. Conclusions: The implementation of the ICDAS has been comprehensively set into motion within the context of our local curriculum and oral healthcare delivery arrangements. However, this will be an ongoing process with further quality assurance measures being required clinically together with the continuing training of new staff. Sharing this ‘framework’ of the ICDAS implementation process should considerably ease the path and reduce the time period of future implementations by other dental teaching institutions.

The objectives of this study are to compare the prevalence of MIH in children seeking dental care spontaneously at the Department of Comprehensive Children's Dentistry of the University of Buenos Aires (UBA) and Department of Pediatric Dentistry of the University of La República (UdelaR) and to analyze the distribution according to year of birth, sex, age, number of affected teeth and maximum degree of severity in molars and incisors. During 2010, nine pediatric dentists from both schools (Kappa = 0.94) assessed all children born between 1993 and 2003 whose 4 first molars and 8 permanent incisors had erupted. Specially designed charts were used to record sex, year of birth, institution, presence of MIH, number of affected incisors and molars and maximum degree of severity for each tooth. Two groups were formed: UBA: A (n = 512) and UdelaR: B (n = 463). 975 children (11.6 +/- 2.67 years) were evaluated. The prevalence of MIH in the total sample was 6.56%, without significant differences between A and B (p = 0.76). There was no significant difference between groups regarding age (p = 0. 95) or sex (p = 0.30). A significant increase was found in both institutions according to year of birth during the study period. (A: p = 0.0017) B: p = 0. 0058). The results of this study show a similar prevalence of MIH among patients seeking dental care at the Schools of Dentistry of the University of Buenos Aires (Argentina) and University of la República (Uruguay). No significant difference was found comparing the distribution by sex, affected teeth or severity of each tooth. A highly significant positive correlation was found regarding the year of birth. The relevance of MIH as an emerging pathology requires studies on larger samples covering the entire countries.

Full Text Available Abstract Background The aims of this study were to determine factors associated with dental visit and to describe barriers to utilisation of oral health care services among antenatal mothers attending the Obstetric and Gynaecology Specialist clinic in Hospital Universiti Sains Malaysia. Methods A structured, self-administered questionnaire was used obtain information on the variables of interest pertaining to the current pregnancy from 124 antenatal mothers. Results The majority of the mothers claimed that their oral health status was good (67.0% or very good (2.4%. On the contrary, most of them admitted of having had at least one oral health problem (59.7% including cavitated (43.5% and painful teeth (15.3%, bleeding gum (21.0%, and bad breath (10.5%. However, only 29% of the mothers visited dentist during the current pregnancy. Factors associated with the mothers' dental visit were exposure to oral health education before the pregnancy and awareness of relationship between poor maternal oral health and adverse pregnancy outcomes with odds ratio of 4.06 (95% CI: 1.67-9.78 and 3.57 (95% CI: 1.30-9.77 respectively. Common excuses given by most mothers include perceptions of not having any oral health problems (65.9%, long waiting time at the clinic (71.6%, and no immediate treatment given by the dentist (64.8%. Conclusions Utilisation of oral health care services among antenatal mothers was low. Mothers who reported dental visit were more likely to be those who had received oral health education before the current pregnancy and knew of the association between poor maternal oral health and adverse pregnancy outcomes. Dissatisfaction with the services rendered and perceptions of not having any oral health problems were the main barriers.

Full Text Available Introduction: Objective Structured Clinical Examination (OSCE is one of the most authentic ways to evaluate clinical skills. The present study aimed at evaluating the attitude of dental prostheses residents of the faculty of dentistry of Tabriz University of Medical Sciences toward this kind of examination. Methods: In this cross sectional-descriptive study, two questionnaires were designed. One questionnaire dealt with nature of OSCE and the other dealt with the attitude of residents about OSCE. After holding the OSCE in July 2012, 2013, and 2014, the questionnaires were delivered to all dental prostheses residents of the Tabriz dental faculty. In total, 40 questionnaires were filled out within three years. Questions included five-choice items based on a Likert scale. Furthermore, the students’ scores in each exam were recorded to evaluate any possible relationship between the acquired grade and the student’s attitude toward the exam. The collected data were analyzed using SPSS17 software (α=5%. Results: Most residents (62.5% referred to the large number of questions as a positive factor. In addition, a majority of residents (90% suffered from high levels of stress during OSCE. There was a close relation between the grade acquired by the residents in the examination and their attitude to OSCE as well as their evaluation about the examination. The students with better grades had more positive attitudes toward OSCE. Conclusion: Considering the satisfaction level of the students in this study, OSCE was held efficiently and may be considered as part of the training program of the residents.
Full Text Available Tooth loss is a kind of handicap and losing a number of teeth makes an individual susceptible to this disability. Having knowledge about the prevalence of partial tooth loss, provides us with a better understanding of social hygiene. On the other hand, having access to such an information, students can be led properly to treat more prevalent cases. The goal of this retrospective study is to investigate the frequency of partial prosthesis classifications, among patients, referred to Shiraz dental faculty. Sexuality, tooth loss classification and its reason and the presence of additional space were studied about all patients (371 females, 205 males from (97-98 to the end of (99-2000.

To introduce and examine a pilot peer observation of teaching (POT) scheme within the Department of Paediatric Dentistry at Glasgow Dental School and its associated outreach centres. All tutors teaching paediatric dentistry were invited to be involved in evaluation of the POT scheme. Participants were randomly paired with a peer, who then observed their teaching and provided constructive feedback. For those consenting to be involved in the evaluation of the scheme, semi-structured, one-to-one interviews were carried out by the principal investigator. POT was found by all participants to be a beneficial process, reassuring those of their teaching styles and giving them ideas to adapt their teaching. POT is an effective method for engaging chair-side tutors in the reflection and development of their teaching practice via observations and scholarly discussion.

For a long time there has been a need to establish a dental school in Kuwait, due to the fact that the majority of dentists working in Kuwait are expatriates from various countries. An Amiri decree in 1996 made it possible, and the first dental students were admitted to the Kuwait University Faculty of Dentistry in 1998. The mission of the Faculty of Dentistry is 'to promote oral health in Kuwait through education, research and cooperation with other professional health care institutions as well as the community at large'. A 6.5-year dental curriculum was completed after 2 years of committee work and was accepted by the University Council in 2001. This curriculum incorporates current trends in medical and dental education, such as the evidence-based and community-based approaches, problem-solving methodology for outcome-based learning, and competency achieved through comprehensive patient care.

The people of Appalachia-West Virginia are culturally unique and are known to have oral health disparities. The purpose of this study was to evaluate dental fear in relation to delayed dental care as a factor influencing oral health behaviors within this culture. A cross sectional study design was used. Participants were urgent care patients in a university dental clinic. The sample included 140 adults over age 18 years. The Dental Fear Survey was used to determine dental fear level. Self-report of delayed dental care was provided by the participants. The Dental Fear Survey was dichotomized at score 33, with higher scores indicating dental fear. The prevalence of dental fear was 47.1% (n=66). There was a significant association of dental fear and dental delay. The unadjusted odds ratio was 2.87 (95% CI: 1.17, 7.04; p=0.021). The adjusted odds ratio was 3.83 (95%CI: 1.14, 12.82; p=0.030), controlling for tobacco use, perceived oral health status, pain, and last dental visit. A difference in dental delay between men and women was not present in this sample. The only significant variable in delayed dental care was dental fear. In Appalachia-West Virginia, there remains a high level of dental fear, despite advances in dental care, techniques, and procedures. Copyright © 2015 The American Dental Hygienists’ Association.

The proper identification of a decedent is not only important for humanitarian and emotional reasons, but also for legal and administrative purposes. During the reconstructive identification process, all necessary information is gathered from the unknown body of the victim and hence that an objective reconstructed profile can be established. Denture marking systems are being used in various situations, and a number of direct and indirect methods are reported. We propose that national identification numbers be incorporated in all removable and fixed prostheses, so as to adopt a single and definitive universal personal identification code with the aim of achieving a uniform, standardized, easy, and fast identification method worldwide for forensic identification.

Full Text Available The dentists are professionals who has stood out among the health professions when it relates to musculoskeletal disorders due to repetitive movements. This study aimed to identify the occurrence of these musculoskeletal pain in teachers and students of the dentistry course at the State University of Bahia (UESB and compare these groups. The study was conducted using the Nordic Musculoskeletal Questionnaire(NMQ, where there are specific questions about ergonomics, prevalence and frequency of pain / discomfort. The sample consisted of 17 teachers and 102 students who perform clinical practice dentistry course of this university. The results show that 82% of students and 71% of docents have any pain or musculoskeletal discomfort in different parts of the body. The students had a higher prevalence musculoskeletal than docents. The students have also increased knowledge about the origin and development of the disease, but it does not perform prevention. This study did not measure whether students are getting better or worse over the musculoskeletal pains during its formation and later professional career. But points out that knowledge of ergonomics, in regular physical activity can change a situation unfavorable musculoskeletal pain, to a favorable situation of these professionals.

Dental radiology is the core diagnostic modality of veterinary dentistry. Dental radiographs assist in detecting hidden painful pathology, estimating the severity of dental conditions, assessing treatment options, providing intraoperative guidance, and also serve to monitor success of prior treatments. Unfortunately, most professional veterinary training programs provide little or no training in veterinary dentistry in general or dental radiology in particular. Although a technical learning curve does exist, the techniques required for producing diagnostic films are not difficult to master. Regular use of dental x-rays will increase the amount of pathology detected, leading to healthier patients and happier clients who notice a difference in how their pet feels. This article covers equipment and materials needed to produce diagnostic intraoral dental films.

The aim of the present study was to investigate factors associated with denture-induced stomatitis (DIS) among denture wearers and their oral and hand carriage of Candida. Sociodemographics and denture and oral hygiene practices were investigated using an interviewer-administered questionnaire in denture wearers with DIS (n = 60) and without DIS (n = 60) selected using a convenience sampling of patients attending the Department of Prosthetic Dentistry, University of Peradeniya, Sri Lanka. Denture and oral hygiene practices and denture quality were scored. DIS and denture hygiene were classified. Oral and hand carriage of Candida was assessed. Middle-aged females were more prone to DIS. The most common DIS pattern was Newton type ΙΙ. The mean age of existing denture of DIS patients was significantly higher than the control. Denture hygiene practice was significantly low in DIS patients. Poor denture hygiene practice and sleep wear of dentures were significantly associated with DIS. The risk of Candida hand carriage in a DIS patient carrying oral Candida was significantly higher than the risk of Candida hand carriage in a healthy denture wearer who carried oral Candida. Old dentures, poor denture hygiene, and sleep wear of dentures might contribute to DIS. Oral Candida in denture wearers could lead to Candida hand carriage. © 2016 John Wiley & Sons Australia, Ltd.

Oral implant rehabilitation should be considered a treatment option for any edentulous patient and Implant Dentistry is currently a discipline taught in the undergraduate formation. The level of knowledge acquired and how the students perceive the quality of training in Implant Dentistry could assess to know if it is necessary to improve the syllabus. A questionnaire was developed with 11 questions: Basic knowledge (7); Perception of training received (2); Ways in which students would receive training (2). To be responded anonymously and voluntarily for undergraduates students in the Faculty of Dentistry (University of Barcelona, Spain). One hundred and seven students, 76 third year (Group A) and 31 fourth year (Group B) answered the questionnaire. In Group A, 98.68% of students and in Group B 93.54% believed they were poorly informed; 100% of both groups would prefer to receive more training as part of the degree or as postgraduate training through modular courses imparted by experts (A: 71,05%, B: 70,96%) Training through postgraduate programs or training given by private businesses were the least desirable options (A: 42%, B: 64.51%). Questions about basic knowledge acquired received varying responses, which might indicate a certain level of confusion in this area. The undergraduate syllabus must be revised to include sufficient content and training to allow the student to indicate implant-based treatments based on evidence. Students would prefer training to be included in the undergraduate syllabus.

To assess the frequency and causes of dental anxiety and their relation to irregular dental visits among adult dental patients. The Dental Anxiety Question (DAQ) included within a self-administered questionnaire was distributed to 1025 patients attending the Interns' Dental Clinics in the Department of Preventive Dental Sciences, College of Dentistry, University of Dammam, Dammam, Kingdom of Saudi Arabia from March 2012 to February 2013. A cross-sectional study design was used. The questionnaire consisted of 22 closed-ended questions divided into 4 sections; 1) demographics, 2) regularity of dental visits, and related causes, 3) DAQ, cancellation of dental appointments, history of previous trauma, dental anxiety provoking factors within dental environment and procedures, and 4) patients' status in dental clinics, preferences of dentists, and perceptions regarding dental anxiety. The prevalence of dental anxiety among the study sample was 27%. Anesthetic injection was the main factor of dental fear (88.2%), while dental surgical procedures (35.7%) and extractions (23%) were the most terrifying dental procedures. Lack of time (79.5%), cost (71.5%), far-situated dental services (62.2%), and fear (57.1%) were causes listed for irregular dental visits; while 31.3% had no specific reason. Irregular dental visits were not related to dental anxiety. Dental anxiety continues to be an obstacle despite the vast improvement in dentistry; and this raises an alert regarding personal and communication factors in the patient-dentist relationship. Factors such as equal distribution of dental services, time, and cost should also be addressed.

Attitudes of dental students regarding the provision of treatment tend to be dentist-centered; however, facilitating mixed student group formation could change such perceptions. The aim of this study was to investigate the perceived scope of practice of dental and dental hygiene students and whether their perceptions of task distribution between dentists and dental hygienists would change following an educational intervention consisting of feedback, intergroup comparison, and competition between mixed-group teams. The study employed a pretest-posttest single group design. Third-year dental students and second-year dental hygiene students at a university in The Netherlands were randomly assigned to intraprofessional teams (four or five members) and received team-based performance feedback and comparison. The intervention was finalized with an award ceremony for the best intraprofessional team. Before and after the intervention, students completed a questionnaire measuring their perceived distribution of ten tasks between dentists and dental hygienists. A total of 38 dental students and 32 dental hygiene students participated in the intervention-all 70 of those eligible. Questionnaires were completed by a total 88.4% (n=61) of the participants: 34 dental (89.5%) and 27 dental hygiene students (84.4%). Dental and dental hygiene students had similar perceptions regarding teeth cleaning (prophylaxis) (p=0.372, p=0.404) and, after the intervention, preventive tasks (p=0.078). Following the intervention, dental students considered four out of ten tasks as less dentist-centered: radiograph for periodontal diagnosis (p=0.003), local anesthesia (p=0.037), teeth cleaning (p=0.037), and periodontal treatment (p=0.045). Dental hygiene students perceived one task as being less dentist-centered after the intervention: radiograph for cariologic diagnosis (p=0.041). This study found that these dental and dental hygiene students had different opinions regarding the scope of practice

The purpose of this work was to analyze surfaces consisting of different restorative materials for shear bond strength (SBS) and failure patterns of metal and ceramic brackets. Bonding involved the use of a universal primer (Monobond® Plus, Ivoclar Vivadent). Six restorative materials were tested, including one composite resin (Clearfil Majesty™ Posterior, Kuraray Noritake Dental), one glass-ceramic material (IPS Empress® Esthetic, Ivoclar Vivadent), one oxide-ceramic material (CORiTEC Zr transpa Disc, imes-icore), two base-metal alloys (remanium® star, Dentaurum; Colado® CC, Ivoclar Vivadent), and one palladium-based alloy (Callisto® 75 Pd, Ivoclar Vivadent). Bovine incisors served as controls. Both metal and ceramic brackets (discovery®/discovery® pearl; Dentaurum) were bonded to the restorative surfaces after sandblasting and pretreatment with Monobond® Plus. A setup modified from DIN 13990-2 was used for SBS testing and adhesive remnant index (ARI)-based analysis of failure patterns. The metal brackets showed the highest mean SBS values on the glass-ceramic material (68.61 N/mm(2)) and the composite resin (67.58 N/mm(2)) and the lowest mean SBS on one of the base-metal alloys (Colado® CC; 14.01 N/mm(2)). The ceramic brackets showed the highest mean SBS on the glass-ceramic material (63.36 N/mm(2)) and the lowest mean SBS on the palladium-based alloy (38.48 N/mm(2)). Significant differences between the metal and ceramic brackets were observed in terms of both SBS values and ARI scores (p restorative materials under metal brackets were found to involve undercuring of the adhesive. Monobond® Plus succeeded in generating high bond strengths of both bracket types on all restorative surfaces. Given our observations of cohesive fracture (including cases of surface avulsion) of the composite-resin and the glass-ceramic samples, we recommend against using these material combinations in clinical practice.

A new universal graphic dental system, Forensic Dental Symbols(©), has been created to provide precision in the construction of dental records, improve standardization, and increase efficiency in dental identification procedures. Two hundred and thirty-four different graphic symbols representing the most frequent clinical status for each tooth were designed. Symbols can be then converted to a typographic font and then are ready to use in any computer. For the appropriate use, manipulation, and storage of dental information generated by the Forensic Dental Symbols(©), Dental Encoder(©) database has been created. The database contains all the information required by INTERPOL Disaster Victim Identification (DVI)-dental-forms. To explore the possibilities that Dental Encoder(©) offers, an antemortem dental database from a Spanish population of 3920 military personnel had been constructed. Data generated by Dental Encoder(©) were classified into sex and age groups. The program can perform an automatic search of the database for cases that match a selected clinical status presented in a single tooth or a combination of situations for several teeth. Moreover, Dental Encoder(©) allows information to be printed on INTERPOL DVI-dental-forms, or the inclusion of any completed form into any document, technical report, or identification of dental report. © 2011 American Academy of Forensic Sciences.

Aim: Evidence-based dentistry (EBD) is an approach to oral health that requires the application and examination of relevant scientific data related to the patient's oral health and his priorities. The aim of this study was to assess knowledge, attitude, and practice of dental students of Isfahan about EBD. Materials and Methods: In this descriptive study, 168 dental students in 3 final years of their education who engaged in clinical practice by consensus sampling were recruited. For data collection, a validated questionnaire was used. The questionnaire was consisted of demographic questions and some questions about four issues: Knowledge of self-assess (KSA), evidence-based practice, actual knowledge and attitude about EBD. Data were analyzed with t-test, one-way ANOVA, Chi-square, and linear regression with SPSS 16. Results: One hundred and thirty-six students from 168 students were filled the questionnaire. The mean of KSA was 13 ± 4.3, mean of usage of useful references in EBD was 16.9 ± 7.6. One-third of students were studied their last article in last 6 months before. The mean of actual knowledge and attitude was 7.4 ± 2.3 and 24 ± 3.8, respectively. The relation between 4 main issues was significant (P < 0.05). Conclusion: By considering overall interest and positive attitude toward learning EBD in dental students, it is highly recommended that practical educational courses about EBD be planned by dental faculties.

[Effectiveness and difficulty of education on nosocomial infection control for pre-clinical practice in the clinic, so-called inclusive clinical practice phase I, for students in the Faculty of Dentistry, Tokyo Medical and Dental University].
Sunakawa, Mitsuhiro; Matsumoto, Hiroyuki
It has been planned to give pre-clinical practice in the clinic, so-called inclusive clinical practice phase I, for fifth-grade students in the School of Dentistry, Faculty of Dentistry, Tokyo Medical and Dental University, to give them the clinical training needed to perform dental practice and clinical practicum for comprehensive patient care, namely inclusive clinical practice phase II. This study analyzed the educative efficiency of the class on nosocomial infection control (NIC) by comparing achievements pre- and post-test, and discussed appropriate education planning on the NIC for dental students. Sixty-two fifth-grade students in the 2007 academic year sat the pre- and post-tests; the mean score and standard deviation of these tests were 5.30 +/- 1.26 (n = 56) and 8.59 +/- 1.18 (n = 59), respectively. There was a statistically significant difference between them (paired t-test, p < 0.01). Another finding was that students with high scores in the post-test did not necessarily achieve high ratings in the pre-test. It is suggested that the introduction of pre- and post-tests and the clarification of main points in the class as a theme of NIC could be a useful tool for increasing the comprehension of students on the theme. Since students at lower grades will attend clinical practice in the university hospital, it is thought that students should be given NIC training early in the clinical course, and the current curriculum should be improved to increase the opportunity for students to study this important issue.

Using cigarettes and alternative tobacco products (ATPs) is associated with negative oral health outcomes, and dental health professionals are poised to help patients quit. The aim of this study was to determine dental, dental hygiene, and advanced dental students' use, knowledge, and beliefs about cigarettes and ATPs, including perceptions about their education in tobacco dependence treatment and counseling experience. All 1,783 students enrolled in the dental, dental hygiene, and postdoctoral dental programs at the New York University College of Dentistry were invited to participate in the survey in 2016. A total of 708 students at least partially completed the survey, for a response rate of 39.7%. In the results, 146 of the students (20.1%) reported ever using cigarettes, while 253 (35.7%) reported ever using any ATP. Regarding tobacco use intervention, the students reported they had not received enough training on ATPs, were neutral about cigarettes, and were somewhat confident and not so confident counseling a cigarette smoker or ATP user, respectively. By their fourth year, 77.8% of the dental students reported they had counseled someone to stop smoking cigarettes, but only 40.7% had counseled someone to stop using ATPs. Overall, all groups of students reported feeling more confident and had received more education on interventions for cigarettes than for ATPs (ptobacco and did not perceive they had received enough training on intervening with patients on use of cigarettes and ATPs. These findings call for a revised tobacco education curriculum for dental, dental hygiene, and advanced dental students, focused on building knowledge and confidence for promoting tobacco dependence treatment.
Assessment of Agreement between Clinical Diagnosis and Pathologic Report in the Soft Tissue Lesions of the Patients Referring to Pathology Department of Dental School, Tehran and Shahid Beheshti University of Medical Sciences During 2005-2008
Full Text Available Introduction: Agreement between clinical and pathologic diagnoses plays an important role in an appropriate treatment plan and it may also prevent serious side effects and problems in patients. This study was conducted to assess the agreement between clinical diagnoses and pathologic reports in soft tissue lesions of patients referring to pathology department of dental school, Tehran and shahid Beheshti university of medical sciences during 2005-2008. Methods: In this retrospective and descriptive study, 300 soft tissue lesions of patients referring to pathology department were selected by census sampling method and then were analyzed. The lesions were classified according to the criteria proposed by reference pathology textbooks and the data records regarding the patients age, gender and clinical and pathologic diagnoses were noted. Concordance between two diagnoses was determined by descriptive statistics. Results: In this study, pathologic findings were golden standard (definitive diagnoses. The results showed the concordance between two clinical and pathologic diagnoses were more than 0/7 except POF and pemphigus. Conclusion: The results showed that the surgeons of oral and maxillofacial surgery in dental departments of Tehran and shahid Beheshti university of medical science provided acceptable diagnoses regarding pathologic lesions during 2005-2008. However, even the slight differences between two diagnoses necessitate all patients to be evaluated clinically and paraclinically in order to propose an accurate scientific diagnosis and prevent the harmful outcomes of the disease. Furthermore most efforts must be done to make more agreements between clinical and pathological diagnoses.

This chapter describes the applications of OCT for imaging in vivo dental and oral tissue. The oral cavity is a diverse environment that includes oral mucosa, gingival tissues, teeth and their supporting structures. Because OCT can image both hard and soft tissues of the oral cavity at high resolution, it offers the unique capacity to identity dental disease before destructive changes have progressed. OCT images depict clinically important anatomical features such as the location of soft tissue attachments, morphological changes in gingival tissue, tooth decay, enamel thickness and decay, as well as the structural integrity of dental restorations. OCT imaging allows for earlier intervention than is possible with current diagnostic modalities.

This report presents findings from a survey of U.S. dental school deans designed to capture their perceptions regarding the rising cost of dental education and its impact on borrowing by dental students to finance their education. The survey included questions about factors influencing the cost of dental education, concerns about dental student borrowing, and financial awareness resources for students. The survey was distributed to the deans of all 63 U.S. dental schools in January 2013; 42 deans responded, for a 67% response rate. The results indicate that, according to the responding deans, new clinical technologies, technology costs, and central university taxes are the main factors that contribute to the increasing cost of dental education. Coupled with reduced state appropriations at public dental schools and declines in private giving at all dental schools, dental school deans face a perplexing set of financial management challenges. Tuition and fees are a primary source of revenue for all dental schools; however, many deans do not have total control over the cost of attending their schools since tuition and fees are often tied to mandates and policies from the parent university and the state legislature. The findings of this study indicate that U.S. dental school deans are aware of and concerned about the impact of increases in tuition and fees on dental student debt and that they are using a variety of strategies to address the growth in dental student borrowing.

Full Text Available Dental anxiety and dental fear are major factors causing much troubles for the people attending to their own personal health. Statistics show that the 25-26-year-olds experience higher dental anxiety than others. This can be accounted for by the diverse, intense effects of a number of psychological factors in this age range that can cause dental fear and dental anxiety.The aim of the present study was to survey the dental anxiety levels among the students of the Faculty of Dentistry in Plovdiv and determine whether they change throughout the course of study. Material and methods. The self-reported assessment scale developed by N. Corah, the Dental Anxiety Scale (DAS was used in the study; it was applied in the form of a questionnaire containing data on gender, age, education. A total of 535 students of all years in the Faculty of Dentistry in Plovdiv were recruited in the study; they were interviewed either individually or in groups. Results and discussion. Anxiety-free students were the most numerous group in the sample (369, 63.08%, which were followed by students showing moderate anxiety. The mean DAS score of the whole sample was 7.83±0.12; the mean scores by groups were as follows: 8.37±0.26 for the first year students (n1, 7.34±0.19 for the second, third and fourth year students (n2, 7.82±0.16 for the fifth and sixth year students (n3. Twenty five (4.27% students experienced high anxiety and 11 students (1.88% - severe anxiety. Analysis of the mean dental anxiety scores for the three groups showed that fear of dental treatment statistically significantly declined with each successive year of study (P = 0.008.Conclusions: Dental students have a significantly higher level of dental anxiety at the beginning of their training than at its end (P <0.01. Enhancing education and awareness affects favourably dental anxiety.

Interprofessional and intraprofessional education (when students from two or more professions or within the same profession, respectively, learn about, from, and/or with each other) is crucial for effective interdisciplinary collaboration. The aims of this study were to assess the effectiveness of a clinical intraprofessional education program for dental and dental hygiene students, based on students' expectations and satisfaction with the program and patients' satisfaction with the team-based care. The pilot program was developed at the University of Tennessee Health Science Center College of Dentistry, where dental hygiene students were paired randomly with dental students scheduled for prophylaxis, scaling and root planing, or periodontal maintenance. Surveys with questions about the students' expectations and satisfaction were distributed to 89 senior dental students and 27 senior dental hygiene students before and after team-based procedures. Another survey was distributed to 17 patients asking about their satisfaction with the team-based care. All 27 dental hygiene students (100% response rate), 51 dental students (57.3% response rate), and all 17 patients (100% response rate) participated in the surveys. The results showed that both the dental and dental hygiene students had high expectations and were overall satisfied with the intraprofessional education. The students' expectations and perceived educational gap (difference between expectations and satisfaction) differed for the dental and dental hygiene students (pstudents were also more satisfied than the female dental students (pstudents' expectations, and the patients were overwhelmingly satisfied with the team-based care. These results suggest that this intraprofessional practice model provided an effective educational experience for both dental and dental hygiene students and patients. The differences between the dental hygiene and dental students' expectations will help in the design of more effective

Full Text Available Background: Calcium metabolism disorders can be acute or chronic and chronic disorders can cause different disease states such as dental problems. Methods: In this descriptive cross-sectional study done in Children's Medical Center affiliated to Tehran University of Medical Sciences during 2005-2009, all (93 patients with hypoparathyroidism, nutritional rickets, hypophosphatemic rickets and renal osteodysthrophy from the endocrinology and nephrology departments of the Center were referred to a dentist there for orodental examination. Subsequently, the frequency of dental problems including taurodontism, enamel hypoplasia, dental abscess, dental caries and gingivitis were recorded and analyzed. Results: Nutritional rickets was the most common disorder in this study and delay in dentition was the most frequent dental problem in the patients (61.9%. Most cases of taurdontism and enamel hypoplasia were seen in patients with hypoparathyroidism (33% and 50%, respectively. Dental abscess, dental caries and gingivitis were more common in patients with renal osteodysthrophia (50%, 90% and 20%, respectively. In addition, dental caries and delay in dentition were the most prevalent disorders in this study (69.8% and 49.5%, respectively. Conclusion: According to the above findings, it seems that effective screening, regular periodic examinations, proper diagnosis and timely treatment of dental diseases are the main principles of prevention of orodental problems. Moreover, dentists as well as pediatricians should be aware of the features of the aforesaid disorders which lead to dental problems so that early intervention could prevent subsequent serious and more invasive dental problems.

An inverse relationship between dental calculus mineralization and dental caries demineralization on teeth has been noted in some studies. Dental calculus may even form superficial layers over existing dental caries and arrest their progression, but this phenomenon has been only rarely documented and infrequently considered in the field of Cariology. To further assess the occurrence of dental calculus arrest of dental caries, this study evaluated a large number of extracted human teeth for the presence and location of dental caries, dental calculus, and dental plaque biofilms. A total of 1,200 teeth were preserved in 10% buffered formal saline, and viewed while moist by a single experienced examiner using a research stereomicroscope at 15-25× magnification. Representative teeth were sectioned and photographed, and their dental plaque biofilms subjected to gram-stain examination with light microscopy at 100× magnification. Dental calculus was observed on 1,140 (95%) of the extracted human teeth, and no dental carious lesions were found underlying dental calculus-covered surfaces on 1,139 of these teeth. However, dental calculus arrest of dental caries was found on one (0.54%) of 187 evaluated teeth that presented with unrestored proximal enamel caries. On the distal surface of a maxillary premolar tooth, dental calculus mineralization filled the outer surface cavitation of an incipient dental caries lesion. The dental calculus-covered carious lesion extended only slightly into enamel, and exhibited a brown pigmentation characteristic of inactive or arrested dental caries. In contrast, the tooth's mesial surface, without a superficial layer of dental calculus, had a large carious lesion going through enamel and deep into dentin. These observations further document the potential protective effects of dental calculus mineralization against dental caries.

The aim of this study was to evaluate in fibroblast cultures the direct cytotoxic effects of etch-and-rinse, self-etch, and universal adhesive systems. The sterile glass cover slips ( n = 3) were then immersed in culture medium to obtain the eluates for the experimental groups: (1) Adper™ Single Bond 2; (2) Ambar; (3) Adper™ Scotchbond™ Multi-Purpose; (4) Scotchbond™ Universal; (5) Ambar Universal; and (6) OptiBond All-In-One. As a negative control, sterile glass cover slips were immersed in culture medium only. After 24 h, the eluate obtained was applied on fibroblast culture. Cell viability and cell morphology were evaluated by MTT assay and SEM, respectively. Data were analyzed by Kruskal-Wallis and Mann-Whitney tests ( α = 0.05). All adhesive systems except universal reduced cell viability in 3T3 cells to between 26.04% and 56.57%, and Scotchbond Universal and Ambar Universal reduced cell viability to 2.13% and 3.57%, respectively, when compared to the negative control. Cytoplasmic membrane shrinkage and cell-free areas with residual membrane fragments from dead cells were observed. In conclusion, improvements in universal adhesive system formulations and their mechanisms of action are not accompanied by increased toxicity compared with those in other systems, warranting commitment to the use of these dentin-pulp complexes.

Picture Archiving and Communication System (PACS) is difficult to implement in the best of situations, but evidence is growing that the benefits are significant. The aims of this study are to analyze the current status of full PACS and establish successful installation standard of dental PACS. Materials and Methods were based on the investigation of current working status and installation standard of PACS, and observation of variable issues to installation of dental PACS. By September 30, 2004, full PACS implementations in their facilities were 88.1% in specialized general hospitals (37 installations out of total 42 hospitals), 59.8% in general hospitals (144 installations out of total 241 hospitals), 12.3% in medical hospitals (116 installations out of total 941 hospitals) and 3.6% in dental hospitals (4 installations out of total 110 hospitals). Only 4 university dental hospitals currently have installed and are operating full PACS. Major obstacle to wide spread of dental PACS is initial high investments. Clinical environments of dental PACS differed from medical situation. Because of characteristic dental practice, the initial investments for dental PACS are generally much greater than those of medical PACS. Also new economic crisis makes users scruple. The best way to overcome these limitations is to establish an economic installation standard for dental PACS. Also the clear technical communication between the customer and the supplier before both sides are committed to the obstacles are critical to its success.

Dental caries is a biofilm-mediated, sugar-driven, multifactorial, dynamic disease that results in the phasic demineralization and remineralization of dental hard tissues. Caries can occur throughout life, both in primary and permanent dentitions, and can damage the tooth crown and, in later life, exposed root surfaces. The balance between pathological and protective factors influences the initiation and progression of caries. This interplay between factors underpins the classification of individuals and groups into caries risk categories, allowing an increasingly tailored approach to care. Dental caries is an unevenly distributed, preventable disease with considerable economic and quality-of-life burdens. The daily use of fluoride toothpaste is seen as the main reason for the overall decline of caries worldwide over recent decades. This Primer aims to provide a global overview of caries, acknowledging the historical era dominated by restoration of tooth decay by surgical means, but focuses on current, progressive and more holistic long-term, patient-centred, tooth-preserving preventive care.
Ten years have passed since the first articles appeared in this new field. The qualities of the laser light together with the need of contactless 3-D measurements for different dental purposes seemed to be extremely promising, but still just a few scientists have used the method and mostly for laboratory studies. For some reason there has been a preponderance for orthodontic measurements. This seems to be a bit peculiar from holographic view compared with measurements for engineering purposes, which usually are made on metals. So naturally holography can become a clinical tool for measurements in the field of fixed bridges, removable partial dentures and implants. One of the problems is that the need for holography in dental research must be fulfilled in collaboration with physicists. Only a two-way communication during an entire experiment can balance both technical and odontological demands and thus give practical and clinical important results. The need for an easy way of handling the evaluation to get all required information is another problem and of course the holographic equipment must be converted to a box easy to handle for everyone. At last the position of dental holography today is going to be carefully examined together with an attempt to look into the hopefully exciting and not to utopic future for this research field.

Our objective was to assess awareness, attitudes, need and demand on replacement of missing teeth according to edentulous space, age, gender, ethnicity, educational level and socio-economical status of the patient. 76.2% of the study group was opined that the missing teeth should be replaced by prosthetic means. Majority were keen in getting them replaced mainly for the comfort in mastication. Although 77.9 and 32.9% were aware of the removable prostheses and implants respectively, only 25.2% knew about tooth supported bridges as an option of replacement of missing teeth. Participants' awareness on tooth and implant supported prostheses is at a higher level. Participants' opinion on need of regular dental visit was statistically significant when gender, ethnicity and education level were considered. The highest demand for replacement of missing teeth was observed in Kennedy class I and II situations in both upper and lower arches. Demand for fixed prostheses was significantly highest in Kennedy class II in upper and lower arches. In conclusion, although removable prosthodontic options are known to most of the patients, their awareness on tooth and implant supported prostheses is also at a higher level. The highest demand for replacement of missing teeth is by patients with Kennedy class I and II situations whereas Kennedy class II being the category with highest demand for fixed prostheses. We recommend that the location of missing teeth to be considered as a priority when educating patients on the most appropriate prosthetic treatment options. Dentists' involvement in educating patients on prosthetic options needs to be improved.

Although first permanent molar hypoconulid absence, third molar agenesis, and small tooth size are all part of evolutionary trend of dental retardation, each bears a different relationship to dental caries. Caries prevalence in the maxillary and mandibular permanent first molars of the Burlington Research Centre serial experimental group at age 16 years was less in the children whose first molars were missing the hypoconulid. Conversely, caries prevalence in mandibular first molars was greater in the children who had agenesis of third molars. The extraction of first molars due to caries was more frequent in children with agenesis of third molars, less frequent in those with absence of hypoconulids of the first molars and unrelated to tooth size. Caries prevalence was less in small teeth, and occurred least in the small mandibular first molars with four cusps. Whereas this is in harmony with the hypothesis that evolutionary dental reductions resulted from the pressure of caries, the increased prevalence of caries and extractions coinciding with third molar agenesis does not support this view. In addition, agenesis of hypoconulids and agenesis of third molars were related to changes in structures unrelated to caries.

During the last few decades, the increasing demands in esthetic dentistry have led to the development of dental composites material that provide similar appearance to the natural teeth. Recently, esthetic trend was an issue which increase the demand for teeth restorations that is similar with the origin. The esthetics of dental composite are more superior compared to amalgam, since its color look similar with natural teeth. Various dental composites have been developed using many type of fillers such as amorphous silica, quartz), borosilicate, Li-Sr-Ba-Al glass and oxide: zirconia and alumina. Researchers in Faculty of Dentistry University of Padjadjaran have prepared dental composites using zirconia-alumina-silica (ZAS) system as the filler. The aim is to improve the mechanical properties and the esthetic of the dental composites. The ZAS was obtained from chemical grade purity chemicals and Indonesia's natural sand as precursors its characterization were also presented. This novel method covers the procedure to synthesis and characterize dental composites in Padjadjaran University and some review about dental composites in global research.

The occurrence of panic symptoms in various anxiety disorders has been associated with more severely impaired and difficult-to-treat cases, but this has not been investigated in dental phobia. We examined the clinical implications of panic symptoms related to sub-clinical and clinically significant dental phobia. The sample consisted of 61 patients at a university dental clinic who endorsed symptoms of dental phobia, 25 of whom met criteria for a formal diagnosis of dental phobia. Participants with dental phobia endorsed more panic symptoms than did those with sub-clinical dental phobia. In the total sample, greater endorsement of panic symptoms was associated with higher dental anxiety, more avoidance of dental procedures, and poorer oral health-related quality of life. Among those with dental phobia, certain panic symptoms exhibited associations with specific anxiety-eliciting dental procedures. Panic symptoms may serve as indicators of clinically significant dental phobia and the need for augmented treatment. Copyright © 2014 Elsevier Ltd. All rights reserved.

This article describes Colombia's development of formal dentistry, its dental school system, curriculum, and dental licensure, and current issues in oral health care. In 1969, there were only 4 dental schools in Colombia; at this writing there are 21. Five dental schools are public and the other 16 are private. Nearly all classes are conducted in Spanish. Undergraduate pre-dental coursework is not a prerequisite for dental school in Colombia. To obtain licensure, Colombian dental students must complete 5 years of study in dental school, earn a diploma, and work for the government for 1 year. There are approximately 41,400 dentists in Colombia, and the number is increasing quickly. However, the unemployment rate among dentists is very high, even though graduation from dental school is extremely difficult. Although the 1,100:1 ratio of citizens to dentists is considered satisfactory, access to dental care is limited due to the high rate of poverty.

The aim of this study was to identify and compare the attitudes of dental students towards dental education in Japan and China. Fifty-four dental students from the Stomatology School of China Medical University and 51 dental students from the Dental Faculty of Kyushu University, Japan, participated in this study. Information was derived from a self-answered questionnaire consisting of 11 items. Significant differences in the responses of the participants from the two countries were detected for 10 of the questionnaire items (P students were satisfied with the teaching faculties of their schools, while only a quarter of the Chinese students indicated satisfaction. A total of 69% of Chinese students thought that learning a foreign language wasted too much time compared with none of the Japanese students. A student-oriented teaching mode was not well accepted by either of the groups, and 62% of Chinese students and 53% of Japanese students wanted to increase the duration of the clinical practice stage of education. The findings from this study enhance our understanding of differences and/or similarities among dental students in the two nations. This information may help to define strategies to improve the quality of dental education, and especially exchange programmes of international students. © 2013 FDI World Dental Federation.
Full Text Available Background: Radiographic imaging as a supportive diagnostic tool is the essential component in treatment planning for dental implant. It help dentist to access target area of implant due to recommendation of many inventions in making radiographic imaging previously. Along with the progress of science and technology, the increasing demand of easier and simpler treatment method, a modern radiographic diagnostic for dental implant is needed. In fact, Makassar, especially in Faculty of Dentistry Hasanuddin University, has only a conventional dental radiography. Researcher wants to optimize the equipment that is used to obtain parameters of the jaw that has been corrected to get accurate dental implant. Purpose: This study aimed to see the difference of radiographic imaging of dental implant size which is going to be placed in patient before and after correction. Method: The type of research is analytical observational with cross sectional design. Sampling method is non random sampling. The amount of samples is 30 people, male and female, aged 20–50 years old. The correction value is evaluated from the parameter result of width, height, and thick of the jaw that were corrected with a metal ball by using conventional dental radiography to see the accuracy. Data is analyzed using SPSS 14 for Windows program with T-test analysis. Result: The result that is obtained by T-Test analysis results with significant value which p<0.05 in the width and height of panoramic radiography technique, the width and height of periapical radiography technique, and the thick of occlusal radiography technique before and after correction. Conclusion: It can be concluded that there is a significant difference before and after the results of panoramic, periapical, and occlusal radiography is corrected.

Full Text Available Introduction: Malocclusions, which present a severe skeletal component, are difficult to solve through orthodontic treatment inpatients at the end of growth and often require a combined orthodontic-surgical treatment. The mandibular propulsion appliances "no compliance" now offer new possibilities for functional orthopedic treatment in borderline cases. Case presentation: A patient at the end of growth with a severe malocclusion (Class II Division 1, open bite with arches' transversaldiscrepancy, refused the hypothesis of an orthodontic-surgical treatment, which represents the gold standard in such occlusal andskeletal problems, especially in subjects at the end of growth; consequently, a complex orthopedic-orthodontic treatment was chosen as the second choice. The patient has been successfully treated also through the use of SUS2 (Sabbagh Universal Spring 2; Dentaurum, Ispringen, Germany, a "no compliance" fixed functional appliance, which carried out a significant sagittal correction. Conclusion: The case report especially highlights the important sagittal correction obtained through the use of SUS2. The SUS2 had a functional outcome, which resulted in the maxillary growth stop and an effective sagittal mandibular growth increase. The SUS2effects, enhanced by elastics biomechanics, led to the bite closure and at the achievement of Class I occlusion.

Full Text Available Background. The unequal distribution of workforce across dental specialties in Nigeria poses a significant problem in the delivery of specialists’ oral healthcare to the Nigerian population. Objectives. To determine dental specialties preferences among dental students at the University of Ibadan, Nigeria, and to explore the factors that influence their choices. Methods. We obtained ethical approval to conduct this study. Only the dental students who rotated through all the dental specialties were selected to participate in this questionnaire-based study. Data were analysed using SPSS version 16 (SPSS Inc., USA. Results. The majority of dental students at the University of Ibadan preferred the oral and maxillofacial surgery (OMS specialty above all other dental specialties, while prosthetic dentistry was least preferred. Of all the factors to take into consideration when choosing a dental specialty, personal interest was the only factor considered by nearly all respondents. Only male respondents considered prestige as an influencing factor in their choice of a specialty. Lifestyle and job description were factors considered by a higher proportion of the male respondents (10/13 than females (5/14. The mean age of the 27 respondents who participated in this study was 22.6 years, 52% of whom were females. Conclusion. OMS was the most preferred specialty among our respondents (n=8. Nearly all dental students chose residency training in the specialty that most appealed to them. The interest of dental students towards the least appealing dental specialties needs to be developed to solve the problem of skewed distribution of the dental workforce in Nigeria. Our findings suggest that this may be accomplished by changing dental students’ perceptions of certain specialties, building on male students’ interests in job security and private practice potential, and the female students’ interests in family-friendly specialties and increasing flexibility
Straightening teeth is an arduous process requiring months, often years, of applying corrective pressure by means of arch wires-better known as brace-which may have to be changed several times in the course of treatment. A new method has been developed by Dr. George Andreasen, orthodontist and dental scientist at the University of Iowa. The key is a new type of arch wire material, called Nitinol, with exceptional elasticity which helps reduce the required number of brace changes. An alloy of nickel and titanium, Nitinol was originally developed for aerospace applications by the Naval Ordnance Laboratory, now the Naval Surface Weapons Laboratory, White Oaks, Maryland. NASA subsequently conducted additional research on the properties of Nitinol and on procedures for processing the metal.

Doses induced by individual dental examinations are low. However, dental radiography accounts for nearly one third of the total number of radiological examinations in the European Union. Therefore, special attention is needed with regard to radiation protection. In order to lower patient doses, the staff performing dental examinations must have competence in imaging as well as in radiation protection issues. This paper presents a systematic review about the core competencies needed by the healthcare staff in performing digital dental radiological imaging quality assurance. The following databases were searched: Pubmed, Cinahl, Pro Quest and IEEXplore digital library. Also volumes of some dental imaging journals and doctoral theses of the Finnish universities educating dentists were searched. The search was performed using both MeSH terms and keywords using the option 'search all text'. The original keywords were: dental imaging, digital, x-ray, panoramic, quality, assurance, competence, competency, skills, knowledge, radiographer, radiologist technician, dentist, oral hygienist, radiation protection and their Finnish synonyms. Core competencies needed by the healthcare staff performing digital dental radiological imaging quality assurance described in the selected studies were: management of dental imaging equipment, competence in image quality and factors associated with it, dose optimization and quality assurance. In the future there will be higher doses in dental imaging due to increasing use of CBCT and digital imaging. The staff performing dental imaging must have competence in dental imaging quality assurance issues found in this review. They also have to practice ethical radiation safety culture in clinical practice.

To determine first-year dental students' current motivation and attitudes for choosing the dental profession at the Faculty of Dental Medicine, Medical University - Sofia, Bulgaria. An anonymous questionnaire, consisting of 12 questions about students' socio-demographic profile and their motivation for choosing dentistry, was administered to 119 first-year dental students at the Faculty of Dental Medicine of the Medical University of Sofia. The study was conducted at the beginning of the 2012-2013 academic year. The data was processed and analyzed with the following software: Microsoft Windows Server 2008 R2; Microsoft SQL Server 2008; Internet Information Server 7.5.; Microsoft SharePoint Server 2010. The majority of the students (73%) were self-motivated for choosing dentistry as a career; 61% of them did not have relatives in the medical profession; 43% chose dental medicine because it is a prestigious, humane and noble profession; 50% - for financial security; 59% - because of the independence that it provides. There were no significant differences in the motivation between males and females. Independence, financial security and 'prestige' were the predominant motivating factors in this group of first-year dental students. Determining the reasons for choosing dentistry has important implications for the selection and training of students as well as for their future job satisfaction.

Full Text Available Asma M Al-Jobair, Maha A AlSarheed Department of Pediatric Dentistry and Orthodontics, College of Dentistry, King Saud University, Riyadh, Saudi Arabia Objective: To evaluate Saudi dental students’ opinions on the qualities and attributes of an effective dental teacher.Methods: This cross-sectional study was conducted between March and May 2014 at the College of Dentistry, King Saud University. Self-administered questionnaires were distributed to all students enrolled in the 2013/2014 academic year. The questionnaire contained 43 items regarding students’ opinions on the qualities and attributes of a good dental teacher. The attributes were grouped into two main categories: performance and personality. Mean and standard deviations were calculated for each item and then for the whole category. Performance and personality were compared between male and female students and between junior and senior students using Mann–Whitney U test.Results: Four hundred and seventy-seven questionnaires were completed, representing a response rate of 79%. Performance attributes were significantly more important than personality attributes to Saudi dental students (P<0.001. Perceptions of performance and personality attributes did not differ between male and female students; however, junior students put more emphasis on personality attributes than senior students.Conclusion: Saudi dental students consider performance attributes more important than personality attributes for their successful learning. Teachers’ educational skills are valued more than the attributes, which do not connect directly to students’ learning process. Keywords: perceptions, dental students, characteristics, dental teacher

Full Text Available Background: Patients with thalassemia major needs more dental care due to their medically compromised condition. The aim of this study was to evaluate the dental health and dental treatment needs of these patients at Zahedan university school of Dentistry in 2009.Materials and Method: In this descriptive-analytical study, 75 patients with thalassemia major were selected in which 42 boys and 33 girls with mean age of 10.79±6.2 referred to community dentistry center as the case group and 75 patients' relatives referred to Zahedan school of Dentistry as the control group. Two groups matched for age and sex. The studied variables were patient's educational level and their parents, dental caries and treatment needs. Statistical analysis was carried out by chi-squared test and t-test.Results: Thalassemic patient had increased average dental caries and missing (d=2.24, m=0.13, D=2.49, M=0.52 than the control group (d=2.13, m=0.05, D=0.97, M=0.35. Pulp therapy was the most needed treatment in patient group and in the other group filling dental caries was needed more. Conclusion: According to the high incidence of dental caries in patient with thalassemic major, effective preventive measures, health education and dental treatment are needed for this group.
Full Text Available Background: Dental waste can be hazardous to humans and the environment. Objective: To determine the current status of dental waste management in private and public dental clinics and private dental offices in Shiraz, southern Iran. Methods: This cross-sectional study was conducted at the Shiraz University of Medical Sciences from February through June 2013. A stratified random sampling method was used to study 86 private offices, 14 private clinics and 10 public clinics. Types of waste studied included mercury and amalgam, lead foil packets, sharps, infectious tissues and fluids, pharmaceuticals and domestic waste materials. Compliance with established standards by the monitored dental offices and clinics and public clinics were compared. Results: 89.1% of dental offices and clinics disposed their infectious waste with domestic waste. Only 60% of centers used standard method for sharps disposal. None of the dental centers disposed their pharmaceutical waste and x-ray fixer waste by standard methods. Less than 10% of centers recycled the amalgam and lead foil pockets waste to the manufacture. Conclusion: Government agencies should establish monitoring programs for all dental offices and clinics to identify noncompliant activity and enforce recommended regulations.

The challenges of health care are increasingly complex and subject to frequent change. Meeting these demands requires that health professionals work in partnership with each other and the patient. One way of contributing to this is for students to learn together. However, effective teamwork requires an education system that helps to foster understanding among all those entering the health workforce. The purpose of this study was to investigate the attitudes towards shared learning of undergraduate dental students and trainee dental technicians in a university dental school/hospital in the United Kingdom. Twenty-five trainee dental technicians and 75 undergraduate dental students took part in the study over five academic years. Data were collected using structured questionnaires. A 100% response rate was achieved from the questionnaires. The results indicated the majority of students recognized the benefits of shared learning and viewed the acquisition of teamworking skills as useful for their future working lives, beneficial to the care of their patients, and likely to enhance professional working relationships. The study also found a positive association of being valued as an individual in the dental team by all student groups. Future dental curricula should provide opportunities to develop effective communication between these two groups and encourage teamworking opportunities. These opportunities need to be systematically developed in the dental curriculum to achieve the desired goals.

The aim of this article is to provide information about dental education in Mexico, including its history, the dental school system, curriculum and dental licensure. In 1977, there were only 59 Mexican dental schools; however, there were 83 schools registered in the last official national count in 2007. Forty-one dental schools are public, and the other 42 are private. Every year the number of private dental schools increases. Admission to dental schools in Mexico requires a high school diploma. All classes are conducted in Spanish. To obtain licensure in Mexico, dental students must complete a 3 to 5-year program plus a year of community service. No formal nationwide standard clinical/didactic curriculum exists in Mexico. There are approximately 153,000 dentists in Mexico, a number that increases each year. The dentist-patient ratio is approximately 1:700. However, the high percentage of inactive licensed dentists in Mexico points to a serious problem.

Virtual autopsy is a medical imaging technique, using full body computed tomography (CT), allowing for a noninvasive and permanent observation of all body parts. For dental identification clinically and radiologically observed ante-mortem (AM) and post-mortem (PM) oral identifiers are compared. The study aimed to verify if a PM dental charting can be performed on virtual reconstructions of full-body CT's using the Interpol dental codes. A sample of 103 PM full-body CT's was collected from the forensic autopsy files of the Department of Forensic Medicine University Hospitals, KU Leuven, Belgium. For validation purposes, 3 of these bodies underwent a complete dental autopsy, a dental radiological and a full-body CT examination. The bodies were scanned in a Siemens Definition Flash CT Scanner (Siemens Medical Solutions, Germany). The images were examined on 8- and 12-bit screen resolution as three-dimensional (3D) reconstructions and as axial, coronal and sagittal slices. InSpace(®) (Siemens Medical Solutions, Germany) software was used for 3D reconstruction. The dental identifiers were charted on pink PM Interpol forms (F1, F2), using the related dental codes. Optimal dental charting was obtained by combining observations on 3D reconstructions and CT slices. It was not feasible to differentiate between different kinds of dental restoration materials. The 12-bit resolution enabled to collect more detailed evidences, mainly related to positions within a tooth. Oral identifiers, not implemented in the Interpol dental coding were observed. Amongst these, the observed (3D) morphological features of dental and maxillofacial structures are important identifiers. The latter can become particularly more relevant towards the future, not only because of the inherent spatial features, yet also because of the increasing preventive dental treatment, and the decreasing application of dental restorations. In conclusion, PM full-body CT examinations need to be implemented in the

Soft skills and hard skills are essential in the practice of dentistry. While hard skills deal with technical proficiency, soft skills relate to a personal values and interpersonal skills that determine a person's ability to fit in a particular situation. These skills contribute to the success of organisations that deal face-to-face with clients. Effective soft skills benefit the dental practice. However, the teaching of soft skills remains a challenge to dental schools. This paper discusses the different soft skills, how they are taught and assessed and the issues that need to be addressed in their teaching and assessment.

Vocational training (VT) is a mandatory 12 month period for UK dental graduates after graduation. Graduates of Irish Dental Schools are eligible to enter the general dental service in Ireland or obtain an NHS performers list number in the UK immediately after qualification. Reports would suggest that some graduates of Irish Dental Schools are choosing to take part in VT in the UK and find the experience beneficial. This study aimed to record the uptake of VT amongst recent graduates from University College Cork and to document their experiences. It was designed to compare the attitudes and experiences of graduates of Irish Dental Schools who undertook VT compared with those who entered the general dental service.

Becoming a dental professional requires one to apply ethical decision making skills and demonstrate high standards of professionalism in practice, including the way professionals present themselves to the public. With social media as an evergrowing part of personal and professional communications, this study aimed to determine the accessibility, amount, and type of unprofessional content on Facebook profiles of dental hygiene and dental students in a college of dentistry. The authors evaluated the online profiles of all 499 dental and dental hygiene students at The Ohio State University using objective measures that included existence of a profile, current privacy settings, and access to personally identifiable information. A sample of profiles were evaluated for unprofessional content including photos, comments, and wall posts. The majority of these students were found to use Facebook, with 61 percent having Facebook profiles. Dental hygiene students were more likely to have a Facebook profile than were dental students: 72.6 percent and 59.1 percent, respectively (p=0.027). The majority of the students' profiles had some form of privacy setting enabled, with only 4 percent being entirely open to the public. Fewer than 2 percent of the students allowed non-friends access to personal information. Based on in-depth analysis of the profiles, fourteen (5.8 percent) instances of unprofessionalism were recorded; the most common unprofessional content involved substance abuse. This study found that these dental and dental hygiene students frequently possessed an identifiable Facebook account and nearly half had some kind of personal information on their profile that could potentially be shared with the public. In some instances, the students gave patients, faculty, and potential employers access to content that is not reflective of a dental professional. Academic institutions should consider implementing policies that bring awareness to and address the use of social media

Interprofessional education (IPE) is a widely recognized and critical component of dental and health professions education and is included in two of the predoctoral education standards required by the Commission on Dental Accreditation (CODA). Following a review of the literature on the state of IPE education in U.S. dental education programs, this article revisits six institutions identified in previous research as exemplars successfully implementing IPE on their campuses. Interviews were conducted with leaders at the following programs: Columbia University, Medical University of South Carolina, University of Colorado Anschutz Medical Campus, University of Florida, University of Minnesota, and Western University of Health Sciences. Strengths and weakness of IPE in dental education are discussed, along with opportunities for the future including reducing barriers to scheduling, increasing intraprofessional education, and consistent outcomes assessment. The article concludes with lessons learned by administrators and suggestions for improving incorporation of these requirements into predoctoral dental education programs by emphasizing the importance of IPE and dentistry's role in overall health. This article was written as part of the project "Advancing Dental Education in the 21 st Century."

Full Text Available Fungi can cause various diseases, and some pathogenic fungi have been detected in the water of dental equipment. This environment offers suitable conditions for fungal biofilms to emerge, which can facilitate mycological contamination. This study verified whether the water employed in the dental units of two dental clinics at the University of Franca was contaminated with fungi. This study also evaluated the ability of the detected fungi to form biofilms. The high-revving engine contained the largest average amount of fungi, 14.93 ± 18.18 CFU/mL. The main fungal species verified in this equipment belonged to the genera Aspergillus spp., Fusarium spp., Candida spp., and Rhodotorula spp. Among the isolated filamentous fungi, only one fungus of the genus Fusarium spp. did not form biofilms. As for yeasts, all the Candida spp. isolates grew as biofilm, but none of the Rhodotorula spp. isolates demonstrated this ability. Given that professionals and patients are often exposed to water and aerosols generated by the dental procedure, the several fungal species detected herein represent a potential risk especially to immunocompromised patients undergoing dental treatment. Therefore, frequent microbiological monitoring of the water employed in dental equipment is crucial to reduce the presence of contaminants.

A trend towards increasingly new forms of dental practice has been observed in the FDI World Dental Federation. Elementary foundations such as the free dentist and therapy choice, and independent, free, self-responsible professional practice may be undermined. The current study is aimed at analyzing the general training framework, organization, and professional types of dental practice in the European Regional Organization (ERO) zone and at critically discussing selected aspects of changes in the dental profession. A questionnaire was developed by the ERO Working-Group "Liberal Dental Practice." Information about dental schools, professional organizations, dental practice regulations, and ambulatory healthcare centers was analyzed. Self-employed dental practice is the most common type of practice (51.7%). Dentists are allowed to work independently immediately after graduation (72.7%). Approximately one-third are organized as compulsory members in chambers/corporations. The density of dentists has a mean of 1,570 inhabitants per dentist. In most countries, there are no special rules for founding dental ambulatory healthcare centers. In a total of 353 universities of the ERO countries surveyed, 16,619 dentists per year were trained, with a trend toward a higher percentage of female students (63%). Despite modern forms of dental practice, the charter of the individual liberal dental profession (CED et al, 2013) should be respected and taken into account on the basis of ethical principles. The commercialization of the dental profession can be neutralized only by establishing and following well-defined ethical principles; oral healthcare quality can thus be ensured without the influence of third parties.

Academic dental institutions face the growing challenge of securing the resources needed to develop a curriculum that incorporates current innovation and technology to ensure that students' learning experiences are relevant to current dental practice. As a result, university-industry relationships are becoming increasingly common in academe. While these relationships facilitate curriculum relevance, they also expose students to external market forces. The purpose of this study was to explore the influence of industry on dental education using a qualitative research study design. Analysis of semistructured interviews with thirteen Dalhousie University dental faculty members revealed two primary themes that suggest a tension between the traditional hierarchical organizational structures guiding curriculum (i.e., authoritarianism) and industry's quest for profit (i.e., entrepreneurialism). Additional themes demonstrate a belief that industry directly influences students' knowledge and understanding of evidence as well as their experience with both the formal and informal curricula. Industry's presence in academe is a concern. Dental educators, as stewards of the profession, must be nimble in brokering industry's presence without compromising the integrity of both the educational program and the teaching institution as a whole.

Full Text Available Objective. The purpose of this review paper is to review the literature regarding the toxicology of mercury from dental amalgam and evaluate current statements on dental amalgam. Materials and Methods. Two key-words “dental amalgam” and “toxicity” were used to search publications on dental amalgam biocompatibility published in peer-reviewed journals written in English. Manual search was also conducted. The most recent declarations and statements were evaluated using information available on the internet. Case reports were excluded from the study. Results. The literature show that mercury released from dental amalgam restorations does not contribute to systemic disease or systemic toxicological effects. No significant effects on the immune system have been demonstrated with the amounts of mercury released from dental amalgam restorations. Only very rarely have there been reported allergic reactions to mercury from amalgam restorations. No evidence supports a relationship between mercury released from dental amalgam and neurological diseases. Almost all of the declarations accessed by the internet stated by official organizations concluded that current data are not sufficient to relate various complaints and mercury release from dental amalgam. Conclusions. Available scientific data do not justify the discontinuation of amalgam use from dental practice or replacement with alternative restorative dental materials.

Full Text Available Dental caries is one of the most common diseases in humans. In modern times, it has reached epidemic proportions. Dental caries is an infectious microbiologic disease of the teeth that results in localized dissolution and destruction of the calcified tissue. Dental caries is a mulitifactorial disease, which is caused by host, agent, and environmental factors. The time factor is important for the development and progression of dental caries. A wide group of microorganisms are identified from carious lesions of which S. mutans , Lactobacillus acidophilus , and Actinomyces viscosus are the main pathogenic species involved in the initiation and development of dental caries. In India, surveys done on school children showed caries prevalence of approximately 58%. Surveys among the U.S. population showed an incidence of 45.3% in children and 93.8% in adults with either past or present coronal caries. Huge amounts of money and time are spent in treating dental caries. Hence, the prevention and control of dental caries is the main aim of public health, eventually the ultimate objective of public health is the elimination of the disease itself. Recently, dental caries vaccines have been developed for the prevention of dental caries. These dental caries vaccines are still in the early stages.

Dental caries is one of the most common chronic childhood diseases affecting a large portion of children in the United States. The prevalence of childhood dental caries in Kentucky is among the highest in the nation. The purposes of this study are to (1) compare sociodemographic differences between caries and no caries groups and (2) investigate factors associated with untreated dental caries among children who visited a mobile dental clinic in South Central Kentucky. Study subjects were children aged 6 to 15 years who participated in the school-based dental sealant program through the mobile dental clinic operated by the Institute for Rural Health at Western Kentucky University between September 2006 and May 2011 (n = 2,453). Descriptive statistics were calculated for sociodemographic factors (age, gender, race/ethnicity, insurance status, and urban versus rural residential location) and caries status. We used chi-square tests to compare sociodemographic differences of children stratified by caries and no caries status as well as three levels of caries severity. We developed a logistic regression model to investigate factors associated with untreated dental caries while controlling for sociodemographic characteristics. The proportion of children having untreated dental caries was 49.7% and the mean number of untreated dental caries was 2.0. The proportion of untreated dental caries was higher in older children, children with no insurance and living in rural residential locations, and caries severity was also higher in these groups. Odds ratio indicated that older ages, not having private insurance (having only public, government-sponsored insurance or no insurance at all) and rural residential location were associated with having untreated dental caries after controlling for sociodemographic characteristics of children. Untreated dental caries was more likely to be present in older children living in rural areas without insurance. Health interventionists may use

The study objectives were to identify the stress levels and to explore the impact of students' year of study and gender on the perceived sources of stress among Malaysian dental students. This was a cross-sectional study involving dental students from year one to year five from private and public universities in Malaysia. The study was formally approved by the Research and Ethics Committee, International Medical University Malaysia. Dental Environment Stress (DES) questionnaire was used for data collection and the gathered data were analyzed using SPSS® version 18. The Kruskal-Wallis and the Mann-Whitney U tests were used to compare stress items across various academic years and universities. A total of five hundred and twenty nine (529) students participated in this study. Fear of failing the course at the end of year exams (mean stress level=5.57); concerns regarding completion of clinical work (mean=5.30); and examination results and grades (mean=5.27) were found as top stressors among dental students. Female students had higher stress scores than males with respect to personal issues, academic performance, educational environment and learning of clinical skills. Students from public universities had higher stress scores than their counterparts from private universities. The Malaysian dental students reported higher levels of stress. Present study identified stressors affecting dental students' academic life, and highlights the importance of stress management programs and other measures to minimize the impact of stress on both academic and personal lives of the students.

The introduction of the landmark mandatory teaching of sign language to undergraduate dental students at the University of the West Indies (UWI), Mona Campus in Kingston, Jamaica, to bridge the communication gap between dentists and their patients is reviewed. A review of over 90 Doctor of Dental Surgery and Doctor of Dental Medicine curricula in North America, the United Kingdom, parts of Europe and Australia showed no inclusion of sign language in those curricula as a mandatory component. In Jamaica, the government's training school for dental auxiliaries served as the forerunner to the UWI's introduction of formal training of sign language in 2012. Outside of the UWI, a couple of dental schools have sign language courses, but none have a mandatory programme as the one at the UWI. Dentists the world over have had to rely on interpreters to sign with their deaf patients. The deaf in Jamaica have not appreciated the fact that dentists cannot sign and they have felt insulted and only go to the dentist in emergency situations. The mandatory inclusion of sign language in the Undergraduate Dental Programme curriculum at The University of the West Indies, Mona Campus, sought to establish a direct communication channel to formally bridge this gap. The programme of two sign language courses and a direct clinical competency requirement was developed during the second year of the first cohort of the newly introduced undergraduate dental programme through a collaborating partnership between two faculties on the Mona Campus. The programme was introduced in 2012 in the third year of the 5-year undergraduate dental programme. To date, two cohorts have completed the programme, and the preliminary findings from an ongoing clinical study have shown a positive impact on dental care access and dental treatment for deaf patients at the UWI Mona Dental Polyclinic. The development of a direct communication channel between dental students and the deaf that has led to increased dental

Dental radiology is quickly becoming integral to the standard of care in veterinary dentistry. This is not only because it is critical for proper patient care, but also because client expectations have increased. Furthermore, providing dental radiographs as a routine service can create significant practice income. This article details numerous conditions that are indications for dental radiographs. As you will see, dental radiographs are often critical for proper diagnosis and treatment. These conditions should not be viewed as unusual; they are present within all of our practices. When you choose not to radiograph these teeth, you leave behind painful pathology. Utilizing the knowledge gained from dental radiographs will both improve patient care and increase acceptance of treatment recommendations. Consequently, this leads to increased numbers of dental procedures performed at your practice.

To compare the levels of career satisfaction expressed by three professional groups working in dental health: dental therapists, dental hygienists and dental practitioners. Level of career satisfaction was assessed using a ten point scale in three surveys. Postal surveys were conducted of all dental therapists and dental hygienists registered with the General Dental Council. Data for dental practitioners were collected as part of the British Dental Association Omnibus Survey 2000. Data are reported for 227 dental therapists, 2,251 dental hygienists and 970 dental practitioners. Significant differences were found between groups in the level of career satisfaction expressed. Dental practitioners were less likely to express high levels of satisfaction in comparison with the other two professional groups. Within each group characteristics of the respondents were associated with satisfaction levels. Younger dental therapists and dental hygienists expressed lower levels of career satisfaction. The level of career satisfaction expressed by dental practitioners was associated with gender, place of work (North vs South UK), year of qualification, size of practice and system of remuneration. Dental practitioners express lower levels of job satisfaction in comparison to other groups of dental health care professionals. Job dissatisfaction among dental practitioners is related to a number of socio-demographic factors.

It is thus of importance to know more about dental students' own experiences with dental anxiety and their understanding of dental anxiety. The aim was to investigate differences in dental anxiety levels between dental students, psychology students, and biology students at a Norwegian university. Materials and methods: A total of 510 students of dentistry, psychology, and biology at the University of Tromsø received a questionnaire consisting of the Modified Dental Anxiety Scale, demographic questions, and questions relating to their last visit to the dentist/dental hygienist; 169 students gave complete responses. Nonparametric tests were used to investigate differences between the student groups. Results: The respondents were 78% female and 22% male; their mean age was 24 years. The dental students showed a significantly lower degree of dental anxiety than the psychology (P<0.001 and biology students (P<0.001. A significant decrease in dental anxiety levels was found between novice and experienced dentistry students (P<0.001. Discussion: The dental students had less dental anxiety compared to psychology students and biology students. Experienced dental students also had less dental anxiety than novice dental students. This could indicate that the dentistry program structure at the university may influence dental anxiety levels. Conclusion: Dental anxiety seemed to be less frequent in dentistry students compared to students of biology or clinical psychology. The practice-oriented dentistry education at the university might contribute to

In 2009, Minnesota Governor Pawlenty signed into law a bill approving the creation of a new dental team member: the dental therapist. The intent of this legislation was to address oral health disparities by creating a dental professional who would expand access to dental care in Minnesota. This study aimed to describe the characteristics of the first class of dental therapy students at the University of Minnesota and to ascertain the values and motivations that led them to choose a career in dental therapy. Four surveys were used to create the composite profile of the ten students in this first dental therapy class: 1) the California Critical Thinking Skills Test, 2) the Learning Type Measure, 3) the Attitudes Toward Healthcare Survey, and 4) a values and motivation survey that included demographic data. The results of the surveys revealed interacting influences of the students' background, personal self-concept, and environment leading to a career decision to pursue dental therapy.

The benefit for the child from the judicious use of diagnostic dental radiography is improved dental health. The risk to the child from dental diagnostic radiation exposure appears to be extremely low. Despite the low risk, the dentist must minimize the child's exposure to ionizing radiation by using sound clinical judgment to determine what radiographs are necessary and to provide children with optimal protection from ionizing radiation

Modern dental alloys have been used for 50 years to produce prosthetic dental restorations. Generally, the crowns and frames of a prosthesis are prepared in dental alloys, and then veneered by feldspar ceramics or composites. In use, the alloys are exposed to the corrosive influence of saliva and bacteria. Metallic dental materials can be classified as precious and non-precious alloys. Precious alloys consist of gold, platinum, and small amounts of non-precious components such as copper, tin, or zinc. The non-precious alloys are based on either nickel or cobalt, alloyed with chrome, molybdenum, manganese, etc. Titanium is used as Grade 2 quality for dental purposes. As well as the dental casting alloys, high purity electroplated gold (99.8 wt.-%) is used in dental technology. This review discusses the corrosion behavior of metallic dental materials with saliva in ''in vitro'' tests and the influence of alloy components on bacteria (Lactobacillus casei and Streptococcus mutans). The test results show that alloys with high gold content, cobalt-based alloys, titanium, and electroplated gold are suitable for use as dental materials. (orig.)

Growing distribution and utilization of digital volume tomography (DVT) extend the spectrum of clinical dental imaging. Additional diagnostic value, however, comes along with an increasing amount of radiation. In contrast, magnetic resonance imaging is a radiation free imaging technique. Furthermore, it offers a high soft tissue contrast. Morphological and numerical dental anomalies, differentiation of periapical lesions and exclusion of complications of dental diseases are field of applications for dental MRI. In addition, detection of caries and periodontal lesions and injury of inferior alveolar nerve are promising application areas in the future.

Dental caries is one of the most common infectious diseases. Of the oral bacteria, mutans streptococci, such as Streptococcus mutans and S. sobrinus, are considered to be causative agents of dental caries in humans. There have been numerous studies of the immunology of mutans streptococci. To control dental caries, dental caries vaccines have been produced using various cell-surface antigens of these organisms. Progress in recombinant DNA technology and peptide synthesis has been applied to the development of recombinant and synthetic peptide vaccines to control dental caries. Significant protective effects against dental caries have been shown in experimental animals, such as mice, rats and monkeys, which have been subcutaneously, orally, or intranasally immunized with these antigens. Only a few studies, however, have examined the efficacy of dental caries vaccines in humans. Recently, local passive immunization using murine monoclonal antibodies, transgenic plant antibodies, egg-yolk antibodies, and bovine milk antibodies to antigens of mutans streptococci have been used to control the colonization of the organisms and the induction of dental caries in human. Such immunization procedures may be a safer approach for controlling human dental caries than active immunization.

Dental allodynia is characterized by recurrent episodes of diffuse, dull and throbbing tooth pain that develops when returning to an indoor room temperature after being exposed for a long period to cold weather. The pain episode may last up to few hours before subsiding. Effective treatment is to properly shield the pulpal tissue of the offending tooth by increasing the protective layer of the dentin/enamel complex. This review underscores the difference in dentin hypersensitivity and offers a mechanistic hypothesis based on the following processes. Repeated exposure to significant positive temperature gradients (from cold to warm generates phenotypic changes of dental primary afferents on selected teeth with subsequent development of a “low-grade” neurogenic inflammation. As a result, nociceptive C-fibers become sensitized and responsive to innocuous temperature gradients because the activation threshold of specific TRP ion channels is lowered and central sensitization takes place. Comprehensive overviews that cover dental innervation and sensory modalities, thermodynamics of tooth structure, mechanisms of dental nociception and the thermal pain are also provided. Keywords: pain, dental pain, thermal allodynia, atypical tooth sensitivity, dentin hypersensitivity

Due to the declining birth rate and aging of Japanese society, the roles and responsibilities of dental hygienists are continuously expanding. Medical professionalism needs to be pursued continuously throughout one's career in order to improve dental care and treatment. Although conceptualising professionalism is essential to the education of health professionals, professionalism in the field of dental hygiene has not been defined or adequately examined in Japan. The purposes of this study are to investigate dental hygienists' perceptions of the constituent elements of professionalism and the factors affecting their perceptions. Semi-structured interviews were conducted with 18 dental hygienists in Japan. Drawing on the conceptualisation of professionalism in medicine described by Van de Camp et al., the transcribed data were thematically analysed. The dental hygienists in this study perceived 70 constituent elements that were categorised into eight core competencies related to professionalism. These competencies were further classified into three main themes: intrapersonal, interpersonal, and public professionalism. There were three sociohistorical factors that affected their perceptions of the constituent elements, namely academic background (university or technical school), the contexts of any previously provided dental care (university hospital or dental clinic), and their social interactions with their colleagues during their engagement in dental practice (dental team or interprofessional team). Moreover, according to their sociohistorical backgrounds, the dental hygienists saw themselves variously as scholars (university graduates), facilitators (university hospital), skillful artisans (dental clinic), or collaborators (interprofessional team). Dental hygienists' perceptions of professionalism are multidimensional and context-dependent, so culture- and professional-specific elements need to be included in educational curricula and continuing professional

Purpose: The purpose of this study was to assess the prevalence of dental anxiety and missed dental appointments due to dental anxiety among patients within three types of private dental offices. Methods: This descriptive, cross-sectional study utilized the Modified Dental Anxiety Scale (MDAS). The MDAS consists of five questions to assess dental anxiety. Demographics and an open-ended question about missed dental appointments due to dental anxiety were included. Linear and logistic regression models were used to analyze anxiety scores as related to gender and age. Participants' responses to the open-ended question were compiled according to themes. Results: Three hundred and eight (n=308) dental patients participated in the study. Using the MDAS cut-off scores of 15 and 19, the prevalence estimates of moderate to high and high dental anxiety within the total study population was 19% and 6.82% respectively. Females had an MDAS score 2.12 times higher than males (pdental appointment due to dental anxiety. Five common themes were coded as the source of dental anxiety: fear of dental experience, previous negative dental experience, cost of treatment, gag reflex, and fear of bad news. Conclusions: Moderate to high dental anxiety was present in 19% of the population sampled. Awareness of patients' dental anxiety level and the utilization of anxiety reducing measures during treatment may encourage routine care. Copyright © 2017 The American Dental Hygienists’ Association.

Experimentation in all aspects of titanium casting at universities and industries throughout the world for the last 20 years has made titanium and titanium-alloy casting nearly feasible for fabricating sound cast dental prostheses, including crowns, inlays, and partial and complete dentures. Titanium casting in dentistry has now almost reached the stage where it can seriously be considered as a new method to compete with dental casting using conventional noble and base-metal alloys. More than anything else, the strength of titanium’s appeal lies in its excellent biocompatibility, coupled with its comparatively low price and abundant supply. Research efforts to overcome some problems associated with this method, including studies on the development of new titanium alloys suitable for dental use, will continue at many research sites internationally.

Preservation of teeth has been possible in 528 head and neck patients treated with irradiation at Centre Georges Leclerc, University of Dijon, by careful adherence to precise dental care. Careful initial dental evaluation with appropriate x rays, restoration of oral hygiene, atraumatic extraction technique where indicated, and institution of a program of topical fluoridation has resulted in an overall incidence of less than 3% post-irradiation dental decay and 2% osteoradionecrosis. In a small group of 22 patient who required extraction post-irradiation, precise, strict technique resulted in successful extraction in all but one patient who subsequently developed osteonecrosis. Soft-based dental prostheses were well tolerated in nearly 90% of patients. Adherence to the described principles of dental care will virtually eliminate post-irradiation decay and osteoradionecrosis

To determine whether or not people from different ethnic backgrounds have different attitudes towards dental esthetics and chose different dental appearances in terms of tooth shade, and to determine whether the dental professional's choice and the individual's own choice have any relationship with what the individual ideally perceives as esthetically pleasing. For this cross-sectional analytical study, 120 volunteer students from the University of Sheffield (excepting dental students) from various ethnic backgrounds, of different ages, of both genders, and with varying degree/educational levels were recruited from the campus. The volunteers were asked to complete a questionnaire containing 9 adapted attitudinal statements regarding positive or negative dental esthetic perceptions in terms of tooth shade, with responses on a 5-point Likert scale from "Entirely agree" to "Entirely disagree". Scores for all attitudinal statements were summed up to give an attitudinal score. The participants' ideal, perceived, and actual (self-assessed and investigatorassessed) tooth shade was also determined using a shade guide and a facial mirror. No association between ethnicity and attitudinal score was found. However, statistically significant associations were found between the participants' degree/educational level (P=0.004, 95% Confidence Interval (CI)=-4.18 to -0.82) and their ideal tooth shade value (P=0.038, 95% CI=-3.53 to -0.11). There were strong correlations between self-assessed and professionally assessed tooth shade value in all ethnic groups, with Spearman's rank correlation coefficient (rho) being ρ>0.6. Regarding ideally desired and perceived tooth shade value, weak correlations were found in all ethnic groups (Spearman's rho being ρethnicity and attitude towards dental esthetics with regard to tooth shade, both ethnicity and dental esthetics are very diverse terms with multiple dimensions, each of which needs further investigation with regard to their mutual

This article reviews current dental education economic challenges such as increasing student tuition and debt, decreasing funds for faculty salaries and the associated faculty shortage, and the high cost of clinic operations and their effect on the future of dentistry. Management tactics to address these issues are also reviewed. Despite recent efforts to change the clinical education model, implementation of proposed faculty recruitment and compensation programs, and creation of education- corporate partnerships, the authors argue that the current economics of public dental education is not sustainable. To remain viable, the dental education system must adopt transformational actions to re-engineer the program for long-term stability. The proposed re-engineering includes strategies in the following three areas: 1) educational process redesign, 2) reduction and redistribution of time in dental school, and 3) development of a regional curriculum. The intent of these strategies is to address the financial challenges, while educating adequate numbers of dentists at a reasonable cost to both the student and the institution in addition to maintaining dental education within research universities as a learned profession.

Dental treatment under general anaesthesia may be needed for some children and adolescents due to medical or behaviour problem. The objective of the study is to identify the type of treatment that has been carried out under GA in Hospital Universiti Sains Malaysia (HUSM). A retrospective record review study from hospital records of dental patients (under 18 years old) receiving dental treatment under GA from 2003 until 2007 were retrieved from the database. Information such as the reason for GA, and the type of treatment provided was recorded in data sheet. The data were analyzed using SPSS 12.0.1 for Windows. It was checked and verified for errors. A total of 349 cases were treated of which 43.6% had medical problems. Patients were mostly diagnosed to have rampant caries (77.1%) and some of them have behavioural problems (34.4%). Treatment pattern in deciduous dentition revealed more extraction (97.8%) as compared to restoration (75.7%) whereas in permanent dentition more restoration was done (24.3%) as compared to extraction (2.2%). Majority of the restorations were done using Glass Ionomer Cements (47.5%). Biopsy (4.3%) contributed mainly to the surgery (24.1%) done during GA. General anesthesia is necessary when dental disease is interfering with health and general well-being of patient and it can facilitated dental treatment allowing dentists to benefit from improved treatment conditions and provide a higher quality of care.

The Editor-in-Chief of the BDJ has previously raised important questions about dental workforce planning and the implications for dental graduates of recent changes and pressures. It is now time to revisit this issue. Much has changed since the last workforce review in England and Wales, and the rate of change is in all probability set to increase. First, at the time of writing this paper the momentous step of including dental care professionals (DCPs) on General Dental Council (GDC) registers in the United Kingdom has recently been completed. Second, the Scope of Practice of all dental professionals has been under consultation by the General Dental Council, and research evidence suggests that greater use should be made of skill-mix in the dental team. Third, within England, Lord Darzi has just published the 'Final Report of the NHS Next Stage Review', which emphasises 'quality care' and 'team-working' as key features of healthcare; this report was accompanied by an important document entitled 'A High Quality Workforce', in which plans for local workforce planning within the NHS are outlined, placing responsibilities at national, local and regional levels. Fourth, policy makers across the UK are wrestling with addressing oral health needs, promoting health and facilitating access to dental care, all of which have implications for the nature and shape of the dental workforce. Fifth, with the impact of globalisation and European policies we are net gainers of dentists as well as having more in training. Sixth, although there have been reviews and policy initiatives by regulatory, professional and other bodies in support of shaping the dental workforce, there has been little serious consideration of skill-mix and funding mechanisms to encourage team-working. Together, these events demand that we enter a fresh debate on the future dental workforce which should extend beyond professional and national boundaries and inform workforce planning. This debate is of great

This was to elucidate dental and skeletal findings in individuals with unilateral and bilateral maxillary dental transpositions. The sample comprised of radiographic materials from 63 individuals with maxillary dental transpositions from the Departments of Odontology at the Universities of Copenhagen and Aarhus and by the Danish municipal orthodontic service. The cases were divided into three groups: unilateral transposition of the canine and first premolar (Type 1U), bilateral transposition of canine and first premolar (Type 1B), and unilateral transposition of canine and lateral incisor (Type 2). The dentitions were analysed regarding agenesis and dental morphological anomalies on panoramic radiographs, and craniofacial aspects were cephalometrically analysed on profile images The results were statistically evaluated. All groups demonstrated increased occurrences of agenesis (Type 1U and Type 1B: 31 agenesis in 15 patients; and Type 2 three agenesis in three patients). Taurodontic root morphology was most dominant in Type 1U. Peg-shaped lateral incisors showed an increased occurrence, though not in Type 1U. Skeletally, Type 1B and Type 1U demonstrated maxillary retrognathia (more pronounced in Type 1B). Type 2 showed a significant posterior inclination of the maxilla. Transpositions of maxillary canines involve dental and skeletal deviations. Dental deviations were predominantly taurodontic root morphology and agenesis. Regarding skeletal deviations, bilateral transpositions of the canines and the first premolars are associated with skeletal changes. Unilateral transpositions are possibly a localised deviation with minor or no skeletal involvements. The results indicate a possible difference in the aetiologies of unilateral and bilateral transpositions.

The objectives of the study reported in this article were to assess dental student leaders' perceptions of educational efforts concerning lesbian, gay, bisexual, and transgender (LGBT) topics and the cultural climate concerning LGBT issues in dental schools in the United States and Canada. In addition, the perceptions of student leaders who self-identified as belonging to the LGBT community and of students with a heterosexual orientation were compared. Data were collected from 113 dental student leaders from twenty-seven dental schools in the United States and three in Canada. Fifty student leaders were females, and sixty-two were males. Only 13.3 percent of the respondents agreed that their dental education prepared them well to treat patients from LGBT backgrounds. The more the student leaders believed that their university has an honest interest in diversity, the better they felt prepared by their dental school program to treat patients from LGBT backgrounds (r=.327; pLGBT orientations, the more they agreed that persons can feel comfortable regardless of their sexual orientation (r=.585; pLGBT backgrounds and that staff, faculty, students, and patients from these backgrounds are not discriminated against.

Management of children's behavior is an integral component of pediatric dental practice. To investigate the oral health care providers' awareness, use and factors for choice of behavior management techniques when attending paediatric dental patients. A cross-sectional study among dental practitioners in Dar es Salaam, Tanzania. Data collection was done through interview using a structured questionnaire. The recorded information included: awareness and application of behavior management techniques (BMT) when attending a child dental patient, factors influencing choice of a particular technique, socio-demographics, level of professional training, working experience and facility profile. Using SPSS program version 18, frequency distributions and cross tabulations analyses were performed. 74 dental practitioners participated in the study, of whom 49 (66.2%) were males and 44 (59.5%) were graduates. Most participants were aware of the behavior management techniques, ranging from 100% for Tell-Show-Do to 86% for distraction. A small proportion (9.5%) reported to have adequate skills, all of them were graduates. The use of universally accepted BMTs was reported by 65% of experienced practitioners, 61% of graduates, 59% of those reporting to have received formal training and all of those reporting to have fair/inadequate skills to apply BMTs (p= 0.01). Most participants were aware of BMTs, although few acknowledged having adequate skills to apply the techniques. They use BMTs during treatment of paediatric dental patients and their choice of the technique is mainly influenced by children's factors.

The significance of the educational environment in health professions academic institutions, increasingly recognized on a global scale, is fundamental to effective student learning. This study was carried out to evaluate students' perceptions of the educational environment in five undergraduate dental institutions in Pakistan. This non-interventional study used a postal questionnaire based on the Dundee Ready Educational Environment Measure (DREEM). The subjects were dental students taking the final professional B.D.S. examination at five dental institutions affiliated with the University of Health Sciences, Lahore, Pakistan. A total of 197 students participated in the study (response rate of 83.82 percent). The overall DREEM score was 115.06 (Cronbach's alpha 0.87). Nine items recorded scores learning and of teachers (p<0.05). Many issues challenge the quality and delivery of dental education in Pakistan, and dental institutions need to develop robust mechanisms to incorporate contemporary international trends in dental education in order to improve the educational environment.

Teeth have long been used as indicators of primate ecology. Early work focused on the links between dental morphology, diet, and behavior, with more recent years emphasizing dental wear, microstructure, development, and biogeochemistry, to understand primate ecology. Our study of Lemur catta at the Beza Mahafaly Special Reserve, Madagascar, has revealed an unusual pattern of severe tooth wear and frequent tooth loss, primarily the result of consuming a fallback food for which these primates are not dentally adapted. Interpreting these data was only possible by combining our areas of expertise (dental anatomy [FC] and primate ecology [MS]). By integrating theoretical, methodological, and applied aspects of both areas of research, we adopted the term "dental ecology"-defined as the broad study of how teeth respond to the environment. Specifically, we view dental ecology as an interpretive framework using teeth as a vehicle for understanding an organism's ecology, which builds upon earlier work, but creates a new synthesis of anatomy and ecology that is only possible with detailed knowledge of living primates. This framework includes (1) identifying patterns of dental pathology and tooth use-wear, within the context of feeding ecology, behavior, habitat variation, and anthropogenic change, (2) assessing ways in which dental development and biogeochemical signals can reflect habitat, environmental change and/or stress, and (3) how dental microstructure and macro-morphology are adapted to, and reflect feeding ecology. Here we define dental ecology, provide a short summary of the development of this perspective, and place our new work into this context. Copyright © 2012 Wiley Periodicals, Inc.

Dental, psychology and mathematics students were divided into cases (high fear) and controls (low fear), defined by cluster analysis, according to the items of the Dental Fear Survey (DFS). Cases (n = 65) and controls (n = 260) participants were paired (1:4) by gender, undergraduate course and social vulnerability. The students self-reported the DFS and a questionnaire about oral health. Descriptive analysis, bivariate and multivariate conditional logistic regression were used as statistical tests with a significance level of 5%. The multivariate model showed that students who reported negative dental experiences in childhood (OR = 2·97; 95% CI: 1·44-6·14), toothache in the last 12 months (OR = 11·31; 95% CI: 4·79-26·68), discomfort during dental treatment (OR = 5·36; 95% CI: 2·53-11·36) and poor self-evaluation of oral health (OR = 3·82; 95% CI: 1·61-8·11) were more likely to have high dental fear. Negative dental experiences in childhood influence dental fear in adulthood. Oral health education should be addressed among university students to reduce dental fear. © 2017 John Wiley & Sons Ltd.

To evaluate the implementation of quality assurance requirements for digital dental radiography in routine clinical practice. The results should be discussed by radiation protection authorities in the context of the relevant legal requirements and current debates on radiation protection. Two hundred digital dental radiographs were randomly selected from the digital database of the Department of Dentistry's Dental and Maxillofacial Surgery Clinic, Ulm University, and evaluated for various aspects of image quality and compliance with radiographic documentation requirements. The dental films were prepared by different radiology assistants (RAs) using one of two digital intraoral radiographic systems: Sirona Heliodent DS, 60 kV, focal spot size: 0.7 mm (group A) or KaVo Gendex 765 DC, 65 kV, focal spot size: 0.4 mm (group B). Radiographic justification was documented in 70.5% of cases, and the radiographic findings in 76.5%. Both variables were documented in the patient records as well as in the software in 14% of cases. Clinical documentation of the required information (name of the responsible dentist and radiology assistant, date, patient name, department, tube voltage, tube current, exposure time, type of radiograph, film size, department and serial number of the dental radiograph) was 100% complete in all cases. Moreover, the department certified according to DIN ISO 9001:2008 specifications demonstrated complete clinical documentation of radiographic justifications and radiographic findings. The entire dentition was visible on 83% of the digital films. The visible area corresponded to the target region on 85.7% of the digital dental radiographs. Seven to 8.5% of the images were classified as "hypometric" or "hypermetric". This study indicates that improvements in radiology training and continuing education fordentists and dental staff performing x-ray examinations are needed to ensure consistent high quality of digital dental radiography.

Globalization of the professions has become a necessity among schools and universities across the world. It has affected the medical and dental professions in terms of curriculum design and student and patient needs. In Japan, where medicine and dentistry are taught mainly in the Japanese language, profession-based courses in English, known as Medical English and Dental English, have been integrated into the existing curriculum among its 83 medical and 29 dental schools. Unfortunately, there is neither a core curriculum nor a model syllabus for these courses. This report is based on a survey, two discussion forums, a workshop, and finally, the drafting of a proposed core curriculum for dental English approved by consensus of the participants from each university. The core curriculum covers the theoretical aspects, including dental English terms and oral pathologies; and practical aspects, including blended learning and dentist-patient communication. It is divided into modules and is recommended to be offered for at least two semesters. The core curriculum is expected to guide curriculum developers in schools where dental English courses are yet to be offered or are still in their early development. It may also serve as a model curriculum to medical and dental schools in countries in Asia, Europe, Africa, and Central and South America, where English is not the medium of instruction.

To prepare dental hygienists for future roles in the health care system, dental hygiene education must prepare graduates with skills, ethics, and values that align with professional responsibility. The objective of this study was to determine the effectiveness of curricular changes designed to develop professional identity and responsibility over the entire span of the dental hygiene curriculum. Twenty-four dental hygiene students at the University of Minnesota were surveyed about their attitudes toward access to dental care, society's and health professionals' responsibility to care for the underserved, and their personal efficacy to provide care for the underserved. Surveys were conducted at three time points in the curriculum. The Attitudes Toward Health Care instrument adapted by Holtzman for dental use was used to survey the students. The findings indicate that this institution's curricular changes were effective in cultivating professional responsibility among these students. Their attitude scores increased across the six-semester curriculum, and students in their last semester of the program believed that all individuals have a right to dental care and that society has an obligation to provide dental care. These students' sense of obligation to care for the needy became stronger and their perceptions of their own ability to impact the community and act as an agent of change also increased.

Full Text Available Ceramics are very important in the science of dental biomaterials. Among all dental ceramics, zirconia is in evidence as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia has been applied as structural material for dental bridges, crowns, inserts, and implants, mostly because of its biocompatibility, high fracture toughness, and radiopacity. However, the clinical success of restorative dentistry has to consider the adhesion to different substrates, which has offered a great challenge to dental zirconia research and development. This study characterizes zirconia as a dental biomaterial, presenting the current consensus and challenges to its dental applications.

In today's society, pets have become important members of families since they give mental peace and healing to families. Although veterinary dentistry is recognized to be essential for animal health, there are few reports on dental treatments of animals and the relationship between veterinarians and dental technicians. The purpose of the present study was to clarify the current situation of dental treatments of animals and to discuss the involvement of dental technicians in veterinary dental treatments and their collaboration with veterinarians. Anonymous self-administered questionnaires were mailed to 16 university hospitals for animals, 17 animal clinics, and 87 zoological gardens, and handed out to 36 participants at the oral disease seminar organized by Nippon Animal Hospital Association. The questionnaires included questions on veterinary dental treatments, ways to learn veterinary dentistry, and details of prosthodontic treatments. Eighty-two valid responses (51.3%) were obtained. While 93.8% of veterinarians recognized the need for veterinary dental treatments, 67.9% were actually implementing dental treatments. Only 23.5% of veterinarians who conducted dental treatments experienced prosthodontic treatments, and the major prostheses used for treatments were fillings and crowns. Most veterinarians had fewer opportunities to acquire knowledge and skills about dental treatments. In addition, the recognition of dental technicians and their specialties was low among veterinarians. The results suggested that the dental technician, as a member of a multi-disciplinary team, can contribute to animal health by providing prosthetic appliances and should make efforts to enhance awareness of their specialty.

To discuss the extent to which an undergraduate dental module addresses dental public health competencies via its different learning pedagogies and to explore the relevance of students' written reflections on these dental public health competencies. This article uses a literature review to situate the extent to which dental public health competencies are addressed by the University of British Columbia undergraduate dental module entitled "Professionalism and Community Services" (PACS). It also uses students' written individual self-reflections (between 100 and 500 words) on community service learning activities to critically illustrate how dental public health competencies support their learning. The PACS dental module is delivered to undergraduate students in all 4 years, more than 190 in total, and addresses six dental public health competencies, including oral health promotion, ethics, and evidence-based practice. The multifaceted pedagogical approach employed to discuss aspects of dentistry related to dental public health includes guest lectures, community activities, small group activities, self-reflection, and reports. Given the falling number of dental public health professionals in North America, the discussed undergraduate pedagogy aims to sensitize future dentists to a career focused on dental public health. Through reflections, students pondered ideas related to dental public health; they also engaged in developing meaningful activities in various underserved communities. Further studies are needed to evaluate the influence of this community-based curriculum upon students' practice choice. © 2014 American Association of Public Health Dentistry.
Full Text Available Dental anomalies are usual congenital malformation that can happen either as isolated findings or as a part of a syndrome. Developmental anomalies influencing the morphology exists in both deciduous and permanent dentition and shows different forms such as gemination, fusion, concrescence, dilaceration, dens evaginatus (DE, enamel pearls, taurodontism or peg-shaped laterals. All These anomalies have clinical significance concerning aesthetics, malocclusion and more necessary preparing of the development of dental decays and oral diseases. Through a search in PubMed, Google, Scopus and Medline, a total of eighty original research papers during 1928-2016 were found with the keywords such as dental anomaly, syndrome, tooth and hypodontia. One hundred review titles were identified, eighty reviews were retrieved that were finally included as being relevant and of sufficient quality. In this review, dental anomalies including gemination, fusion, concrescence, dilaceration, dens invaginatus, DE, taurodontism, enamel pearls, fluorosis, peg-shaped laterals, dentinal dysplasia, regional odontodysplasia and hypodontia are discussed. Diagnosing dental abnormality needs a thorough evaluation of the patient, involving a medical, dental, familial and clinical history. Clinical examination and radiographic evaluation and in some of the cases, specific laboratory tests are also needed. Developmental dental anomalies require careful examination and treatment planning. Where one anomaly is present, clinicians should suspect that other anomalies may also be present. Moreover, careful clinical and radiographical examination is required. Furthermore, more complex cases need multidisciplinary planning and treatment.

The reintroduction and development of safe motorized instruments, the increased availability of continuing education, and the understanding and implementation of appropriate procedures allow practitioners to provide better dental care. Veterinarians realize that sedation, analgesia, a full-mouth speculum, and proper instrumentation are necessary to provide these services. Continued instrument design, future research, and new treatment and prophylactic protocols should have a positive impact on the future of equine dental health. New and rediscovered procedures for equilibrating equine occlusion are allowing horses to masticate more efficiently, carry a bit more comfortably, and experience improved performance. The horse, the horse owner, and the veterinary profession all benefit from providing complete equine dental care.

Dental surgeries refer to procedures that affect the dental tissues or their supporting structures. With the development of specific, efficacious, and conservative treatments, morbidity risks have been lowered and chances of benefiting the health of equids improved. Advances in quality of sedation, analgesia, and locoregional anesthesia allow a majority of dental surgeries to be performed in the standing patient. This update focuses on an orthograde endodontic technique, a minimally invasive buccotomy technique, with the potential to combine it with a transbuccal screw extraction technique, and revisits the AO pinless external fixator for fractures of the body of the mandible.

Modern dentistry can not exist without dental implantation. This work is devoted to study of the "bone-implant" system and to optimization of dental prostheses installation. Modern non-invasive methods such as MRI an 3D-scanning as well as numerical calculations and 3D-prototyping allow to optimize all of stages of dental prosthetics. An integrated approach to the planning of implant surgery can significantly reduce the risk of complications in the first few days after treatment, and throughout the period of operation of the prosthesis.

ABSTRACT QUESTION Many of my patients have asked me if they should defer dental treatment until after they have given birth. Is there any risk associated with performing dental treatments during pregnancy? ANSWER Appropriate and timely dental care can lead to improved pregnancy outcomes as well as greater comfort for the woman. The treatment of periodontitis, as well as the use of local anesthetics, amalgams, and x-ray scans, does not pose an increased risk to the developing fetus and is, in fact, important in contributing to maintaining optimal health for mother and baby.

The University Museum of the University of Utrecht houses within its walls a dentistry collection. A range of dental instruments is on display here which have been used through the ages to deliver people from toothaches. A long time passed, however, before instruments for tooth extraction had been developed which, with the benefit of anatomical knowledge, could effectively grasp teeth. In the middle of the 19th century, general anaesthetics were (re) discovered and that represented an enormous breakthrough. The 'tooth operator' was finally able to treat the patient in a relaxed manner. That opened up a world of medical possibilities. Musclemen who could restrain the patient were no longer necessary and in surgical treatments time became a much less pressing factor. From the beginning of the 20th century, the increase in medical knowledge also made huge advances possible, and the possibilities for dental treatment multiplied.

Although identification of risks to dental healthcare workers has been explored in several industrialized nations, very little data is available from developing countries. This paper examines the occupational hazards present in the dental environment and reports survey results concerning attitudes and activities of a group of Nigerian dental care providers. A survey on occupational hazards was conducted among the clinical dental staff at the Dental Hospital of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife in Osun State, Nigeria. Thirty eight of the forty staff responded, yielding a response rate of 95%. Subject ages ranged from 26 to 56 years with approximately 25% in the 31-46 year old bracket. All of the staff were aware of the occupational exposure to hazards, and the majority had attended seminars/workshops on the subject. Only five staff members (13.2%) owned a health insurance policy and 26 (68.4%) had been vaccinated against Hepatitis B infection. All dentists (24) had been vaccinated compared with only two non-dentists; this relationship was significant (p= 30.07, chi2=0.000). Fourteen members of the clinical staff (36.8%) could recall a sharp injury in the past six months, and the majority (71.1%) had regular contact with dental amalgam. Wearing protective eye goggles was the least employed cross infection control measure, while backache was the most frequently experienced hazard in 47% of the subjects. The need for Hepatitis B vaccinations for all members of the staff was emphasized, and the enforcement of strict cross infection control measures was recommended. The physical activities and body positions that predispose workers to backaches were identified and staff education on the prevention of backaches was provided.

The number of dental radiographs taken in the UK has steadily increased over the past 20 years--recently estimating around 18 million taken in the general dental services alone, and dental radiographs now account for nearly 25% of all medical radiographic exposures. Radiographs remain our most useful diagnostic aid. Their strength is in demonstrating hard tissue pathology, which makes radiographs particularly effective in the maxillofacial region. Although well accepted in this capacity, there remain a number of limitations and drawbacks to conventional radiographs which recent developments have begun to overcome. There have been improvements in the scope and capabilities of dental imaging equipment. There has also been a continuing effort to reduce radiation-induced harm by limiting our exposure to it. This has been possible both through the introduction of new methods and protocols for reducing individual radiation exposures and by the creation of guidelines for selecting radiographs more effectively and thereby reducing the total number of radiographs taken.

Dental caries is one of the most common diseases affecting children in Saudi Arabia despite the availability of free dental services. School-based dental screening could be a potential intervention that impacts uptake of dental services, and subsequently, dental caries' levels. The purpose of this study is to evaluate the effectiveness of two alternative approaches for school-based dental screening in promoting dental attendance and reducing untreated dental caries among primary schoolchildren. This is a cluster randomised controlled trial comparing referral of screened-positive children to a specific treatment facility (King Saud University Dental College) against conventional referral (information letter advising parents to take their child to a dentist). A thousand and ten children in 16 schools in Riyadh, Saudi Arabia, will be recruited for the trial. Schools (clusters) will be randomly selected and allocated to either group. Clinical assessment for dental caries will be conducted at baseline and after 12 months by dentists using the World Health Organisation (WHO) criteria. Data on sociodemographic, behavioural factors and children's dental visits will be collected through structured questionnaires at baseline and follow-up. The primary outcome is the change in number of teeth with untreated dental caries 12 months after referral. Secondary outcomes are the changes in the proportions of children having untreated caries and of those who visited the dentist over the trial period. This project should provide high level of evidence on the clinical benefits of school dental screening. The findings should potentially inform policies related to the continuation/implementation of school-based dental screening in Saudi Arabia. ClinicalTrials.gov , ID: NCT03345680 .

Apparatus is described for improving the handling rate of patients in panoramic dental radiography when tube head-camera assembly of a low silhouette panoramic dental X-ray machine is rotated for a scan in one direction only. This is effected by fast return of the tube head-camera assembly with its simultaneous elevation, thus facilitating the radiographed patient's exit from the machine and the entrance of another patient. Fast speed is about twice the scanning speed. (author)

Full Text Available Background/Aim. Severe dental anxiety (SDA is the most severe form of dental anxiety, thus the aim of this study was to determine the factors associated with SDA in students of health-related disciplines. Methods. In this case-control study the cases were students with severe dental anxiety. The study was conducted at the Faculty of Medical Sciences, University of Kragujevac, Serbia. The participants were undergraduate students attending lectures during spring semester 2010/2011 (n = 1,812. A random sample of 800 students was assessed for the association between various risk factors and the severe dental anxiety. The main outcome measures were the data on demographics, dental anxiety, habits concerning oral hygiene, nutrition, general anxiety and (comorbidity which were collected from the study participants by semi-structured questionnaire. Results. Less frequent visits to the dentist (OR adjusted = 7.02 [2.65; 18.60] and visiting the dentist only when there is a dental problem (OR adjusted = 8.08 [1.28; 50.93] were associated with severe dental anxiety. The same was true for improper oral hygiene (OR adjusted = 4.25 [1.16; 15.60]. Factors as changing toothbrush more frequently (OR adjusted = 0.33 [0.14; 0.76] and having chronic disease (OR adjusted = 0.01 [0.00; 0.09] were inversely associated with severe dental anxiety. The level of education of students was not associated with severe dental anxiety. Conclusion. Inappropriate oral hygiene, less frequent changes of a toothbrush and less frequent visits to the dentist are important risk factors for severe dental anxiety.

The objectives of this study were to survey the radiographic exposure parameters, to measure the patient doses for intraoral dental radiography nationwide, and thus to establish the diagnostic reference levels (DRLs) in intraoral dental X-ray examination in Korea. One hundred two intraoral dental radiographic machines from all regions of South Korea were selected for this study. Radiographic exposure parameters, size of hospital, type of image receptor system, installation duration of machine, and type of dental X-ray machine were documented. Patient entrance doses (PED) and dose-area products (DAP) were measured three times at the end of the exit cone of the X-ray unit with a DAP meter (DIAMENTOR M4-KDK, PTW, Freiburg, Germany) for adult mandibular molar intraoral dental radiography, and corrections were made for room temperature and pressure. Measured PED and DAP were averaged and compared according to the size of hospital, type of image receptor system, installation duration, and type of dental X-ray machine. The mean exposure parameters were 62.6 kVp, 7.9 mA, and 0.5 second for adult mandibular molar intraoral dental radiography. The mean patient dose was 2.11 mGy (PED) and 59.4 mGycm2 (DAP) and the third quartile one 3.07 mGy (PED) and 87.4 mGycm 2 (DAP). Doses at university dental hospitals were lower than those at dental clinics (p 2 (DAP) as the DRLs in adult mandibular molar intraoral dental radiography in Korea.

Full Text Available Dental erosion is a multifactorial condition. The consideration of chemical, biological and behavioral factors is fundamental for its prevention and therapy. Among the biological factors, saliva is one of the most important parameters in the protection against erosive wear. Objective: This review discusses the role of salivary factors on the development of dental erosion. Material and Methods: A search was undertaken on MeDLINe website for papers from 1969 to 2010. The keywords used in the research were "saliva", "acquired pellicle", "salivary flow", "salivary buffering capacity" and "dental erosion". Inclusion of studies, data extraction and quality assessment were undertaken independently and in duplicate by two members of the review team. Disagreements were solved by discussion and consensus or by a third party. Results: Several characteristics and properties of saliva play an important role in dental erosion. Salivary clearance gradually eliminates the acids through swallowing and saliva presents buffering capacity causing neutralization and buffering of dietary acids. Salivary flow allows dilution of the acids. In addition, saliva is supersaturated with respect to tooth mineral, providing calcium, phosphate and fluoride necessary for remineralization after an erosive challenge. Furthermore, many proteins present in saliva and acquired pellicle play an important role in dental erosion. Conclusions: Saliva is the most important biological factor affecting the progression of dental erosion. Knowledge of its components and properties involved in this protective role can drive the development of preventive measures targeting to enhance its known beneficial effects.

Sound enamel was a control. After 10 weeks the 72 hours old dental plaque was collected from surface of restorations and control using sterile probe. Total amount of 68 dental plaques were investigated. Each plaque was placed on scaled and sterile aluminum foil. The moist weight of dental plaque was scaled. Dental plaque was moved into 7 ml 0.85% NaCl solution reduced by cystein chlorine hydrogen and disintegrated by ultrasounds (power:100 Watt, wave amplitude: 5 micorm). The suspension of dental plaque was serially diluted from 10(-4) to 10(-5) in sterile 0,85% NaCl solution, and seeded with amount of 0.1 ml on appropriate base. In dental plaque trials the amount of cariogenic bacteria was calculated--Streptococcus mutans, Streptococcus, Lactobacillus, Veillonella and Neisseria, and also total amount of aerobic and anaerobic bacteria was measured. Microbiologic studies were performed in Institute of Microbiology, Medical University, Łódź. Statistical analysis of collected data was accomplished. In 72 hours old dental plaques collected from the surfaces of Ketac -Molar, Fuji II LC, Charisma after 10 weeks since being placed into the class V cavity, results show no statistically significant differences in the amount of Streptococcus mutans, Streptococcus spp., Lactobacillus spp., Veillonella spp., Neisseria spp, in total amount of aerobic and anaerobic bacteria and in the quantity proportion of Streptococcus mutans versus Streptococcus spp. in comparison

To investigate the potential influence of standard dental materials on dental MRI (dMRI) by estimating the magnetic susceptibility with the help of the MRI-based geometric distortion method and to classify the materials from the standpoint of dMRI. A series of standard dental materials was studied on a 1.5 T MRI system using spin echo and gradient echo pulse sequences and their magnetic susceptibility was estimated using the geometric method. Measurements on samples of dental materials were supported by in vivo examples obtained in dedicated dMRI procedures. The tested materials showed a range of distortion degrees. The following materials were classified as fully compatible materials that can be present even in the tooth of interest: the resin-based sealer AH Plus(®) (Dentsply, Maillefer, Germany), glass ionomer cement, gutta-percha, zirconium dioxide and composites from one of the tested manufacturers. Interestingly, composites provided by the other manufacturer caused relatively strong distortions and were therefore classified as compatible I, along with amalgam, gold alloy, gold-ceramic crowns, titanium alloy and NiTi orthodontic wires. Materials, the magnetic susceptibility of which differed from that of water by more than 200 ppm, were classified as non-compatible materials that should not be present in the patient's mouth for any dMRI applications. They included stainless steel orthodontic appliances and CoCr. A classification of the materials that complies with the standard grouping of materials according to their magnetic susceptibility was proposed and adopted for the purposes of dMRI. The proposed classification can serve as a guideline in future dMRI research.

Total expenditures and revenues of 58 US dental school were derived from reports of the ADA Division of Educational Measurements. These financial data were studied by type of dental school (public, state-related private, and private) and by expenditure/revenue categories. Dental schools showed little diversity in expenditures: most were directed toward instruction; few were directed toward research or continuing education. Several distinctive patterns among the three types of dental schools in revenues were observed. Two configurations emerged: public and state-related private dental schools receive more than 75% of their revenues from government and tuition, and private dental schools, more than 50%.

The aim of this cross-sectional study was to evaluate the skeletal maturation assessed through cervical vertebral maturation (CVM) and dental age, in normal weight, pre-obese and obese patients, using the Body Mass Index (BMI) and the Dual energy X-ray Absorptiometry (DXA). A group of 107 healthy patients, aged between 6 and 12 years (mean age 8.77∓1.79), underwent anthropometric measurements, BMI calculation, and DXA exam at the Department of Neuroscience, Human Nutrition Unit, University of Rome "Tor Vergata" and the assessment of skeletal and dental age at the Paediatric Dentistry Unit of PTV Hospital, University of Rome "Tor Vergata". The subjects were classified as underweight, normal weight, pre-obese and obese according to FM% McCarthy cut-offs classification and BMI classification. The analyses were performed using the SPSS software (version 16; SPSS Inc., Chicago IL, USA). The assessment of differences through the means of continuous variables among the different groups were analysed using the One-Way-Anova test. The Student's t test was also applied for each group of children (using McCarthy and BMI classifications) between chronological and skeletal-dental age; the Fisher's exact test was performed between the gender categorical variable and McCarthy cut-offs classification, and between McCarthy and BMI classifications. Besides, to evaluate the association between skeletal and dental age, a Pearson correlation coefficient was calculated. In all the assessments a significant level of alpha = 0.05 was considered. The comparison between BMI and DXA data shows statistically significant differences between BMI- FM% (McCarthy cut-offs) classifications (p≤0.001). According to FM% (McCarthy cut-offs) classification, from the Anova analysis among the groups a statistically significant difference between skeletal age (p=0.03) and dental age (p=0.02) was observed, while the difference related to the chronological age (p=0.22) among the groups, was not

The aim of the study was to investigate caries experience and dental care index in diabetic children and to determine if correlation exists between caries experience and metabolic control, insulin treatment, and the duration of diabetes. The study group consisted of 52 children and adolescents, 3-16 years of age with type 1 diabetes attending the outpatient diabetic clinic at Ghent University Hospital, Belgium. Fifty healthy subjects recruited from the paediatric dental clinic served as the control group. Caries lesions were assessed using DMF-index both at cavity and non-cavity levels. Participants and/or their guardians provided information about oral hygiene habits and dietary habits. Diabetes-related data (type, duration, insulin regimen) were collected from medical records and completed with the lab data on HbAlc. It became clear that, although children with type 1 diabetes mellitus could be expected to run a potential high caries risk taking into account the diabetes-associated biological and behavioural alterations, no significant differences were observed regarding caries experience and dental care between diabetic children and healthy controls. The level of untreated dental decay among the diabetic children is, however, considerably high, which was reflected by a significant lower dental attendance. © 2010 The Authors.

The objective of this study was to assess dental students' attitudes toward underserved populations across their four years of dental school. Students at the Herman Ostrow School of Dentistry of the University of Southern California were invited to take part in the study. Participating students completed a questionnaire on their attitudes toward the underserved at three time points: 1) during orientation week; 2) at the end of their second year after taking part in some community dental programs; and 3) at the end of their fourth year after they had completed all their mandatory and volunteer rotations in community dental programs. Students' attitudes were measured in four categories: societal expectations, dentist/student responsibility, personal efficacy, and access to care. First-year students scored 85 out of a maximum of 115 on the questionnaire. Female students scored higher than male students (P=0.006). Age, debt, and past history of volunteer work were not related to first-year students' total attitude scores; however, students with a history of volunteer experience scored higher on the dentist/student responsibility category (P=0.04). Students' attitude scores declined across the four years of dental school (P=0.001). The same patterns were evident for all categories except societal expectations. The decline was not related to age, gender, debt, or volunteer work experience. Follow-up studies are needed to help explain the factors that may be related to this decline.

Objectives: To evaluate the dental anxiety level and the degree of acceptance of laser assisted pedodontic treatments from the children part. Also, we want to underline the advantages of laser use in pediatric dentistry, to make this technology widely used in treating dental problems of our children patients. Methods: Thirty pediatric dental patients presented in the Department of Pedodontics, University of Medicine and Pharmacy "Victor Babeş", Timişoara were evaluated using the Wong-Baker pain rating scale, wich was administered postoperatory to all patients, to assess their level of laser therapy acceptance. Results: Wong-Baker faces pain rating scale (WBFPS) has good validity and high specificity; generally it's easy for children to use, easy to compare and has good feasibility. Laser treatment has been accepted and tolerated by pediatric patients for its ability to reduce or eliminate pain. Around 70% of the total sample showed an excellent acceptance of laser dental treatment. Conclusions: Laser technology is useful and effective in many clinical situations encountered in pediatric dentistry and a good level of pacient acceptance is reported during all laser procedures on hard and soft tissues.

Calibration in diagnosis and treatment planning is difficult to achieve due to variations that exist in clinical interpretation. To determine if dental faculty members are consistent in teaching how to diagnose and treat periodontal disease, variations among dental students can be evaluated. A previous study reported high variability in diagnoses and treatment plans of periodontal cases at Indiana University School of Dentistry. This study aimed to build on that one by extending the research to two additional schools: Marquette University School of Dentistry and West Virginia University School of Dentistry. Diagnosis and treatment planning by 40 third- and fourth-year dental students were assessed at each of the schools. Students were asked to select the diagnosis and treatment plans on a questionnaire pertaining to 11 cases. Their responses were compared using chi-square tests, and multirater kappa statistics were used to assess agreement between classes and between schools. Logistic regression models were used to evaluate the effects of school, class year, prior experience, and GPA/class rank on correct responses. One case had a statistically significant difference in responses between third- and fourth-year dental students. Kappas for school agreement and class agreement were low. The students from Indiana University had higher diagnosis and treatment agreements than the Marquette University students, and the Marquette students fared better than the West Virginia University students. This study can help restructure future periodontal courses for a better understanding of periodontal diagnosis and treatment planning.

Due to postural demands, dental professionals are at high risk for developing work-related musculoskeletal disorders (WMSDs). Dental clinicians' lack of ergonomic awareness may impede the clinical application of recommendations to improve their posture. The aim of this study was to determine whether feedback involving photography and self-assessment would improve dental hygiene students' ergonomic scores and accuracy of their ergonomic self-assessments. The study involved a randomized control design and used a convenience sample of all 32 junior-year dental hygiene students enrolled in the autumn 2016 term in The Ohio State University baccalaureate dental hygiene program. Sixteen students were randomly assigned to each of two groups (control and training). At weeks one and four, all participants were photographed and completed ergonomic self-evaluations using the Modified-Dental Operator Posture Assessment Instrument (M-DOPAI). During weeks two and three, participants in the training group were photographed again and used those photographs to complete ergonomic self-assessments. All participants' pre-training and post-training photographs were given ergonomic scores by three raters. Students' self-assessments in the control group and faculty evaluations of the training group showed significant improvement in scores over time (F(1,60)=4.25, phygiene students' self-assessments using photographs resulted in improvements in their ergonomic scores and increased accuracy of their ergonomic self-assessments. Any improvement in ergonomic score or awareness can help reduce the risks for WMSDs, especially among dental clinicians.

Continuous anticoagulation therapy is used to prevent heart attacks, strokes, and other embolic complications. When patients receiving anticoagulation therapy undergo dental surgery, a decision must be made about whether to continue anticoagulation therapy and risk bleeding complications or briefly interrupt anticoagulation therapy and increase the risk of developing embolic complications. Results from decades of studies of thousands of dental patients receiving anticoagulation therapy reveal that bleeding complications requiring more than local measures for hemostasis have been rare and never fatal. However, embolic complications (some of which were fatal and others possibly permanently debilitating) sometimes have occurred in patients whose anticoagulation therapy was interrupted for dental procedures. Although there is now virtually universal consensus among national medical and dental groups and other experts that anticoagulation therapy should not be interrupted for most dental surgery, there are still some arguments made supporting anticoagulation therapy interruption. An analysis of these arguments shows them to be based on a collection of myths and half-truths rather than on logical scientific conclusions. The time has come to stop anticoagulation therapy interruption for dental procedures. Copyright © 2018 American Dental Association. Published by Elsevier Inc. All rights reserved.

Dental schools around the world face new challenges that raise issues with regard to how they are governed, led and managed. With rapid societal changes, including globalization and consumerism, the roles of universities and their funding have become intensely debated topics. When financial burdens on universities increase, so does the pressure on dental schools. This is exacerbated by the relative expense of running dental schools and also by the limited understanding of both university managers and the public of the nature and scope of dentistry as a profession. In these circumstances, it is essential for dental schools to have good systems of leadership and management in place so that they can not only survive in difficult times, but flourish in the longer term. This paper discusses the concept of governance and how it relates to leadership, management and administration in dental schools and hospitals. Various approaches to governance and management in dental schools on different continents and regions are summarized and contrasted. A number of general governance and leadership issues are addressed. For example, a basic principle supported by the Working Group is that an effective governance structure must link authority and responsibility to performance and review, i.e. accountability, and that the mechanism for achieving this should be transparent. The paper also addresses issues specific to governing, leading and managing dental schools. Being a dean of a modern dental school is a very demanding role and some issues relating to this role are raised, including: dilemmas facing deans, preparing to be dean and succession planning. The importance of establishing a shared vision and mission, and creating the right culture and climate within a dental school, are emphasized. The Working Group advocates establishing a culture of scholarship in dental schools for both teaching and research. The paper addresses the need for effective staff management, motivation and

An ad hoc Committee on Sabbaticals created by the Council of Faculties of the AADS surveyed sabbatical policies and their implementation at dental schools in the United States. Data from a questionnaire completed by 56 of 60 members of the Council of Faculties reveal that a majority of U.S. dental schools have sabbatical policies but that dental educators are less likely to apply for or to be awarded sabbaticals than educators from other parts of the university, except perhaps the medical school. Information was also obtained on the regulations governing sabbaticals--interval between leaves, rates of remuneration, and rules defining how the leave may be spent. Finally, suggestions are made as to how this important benefit of academic life might be made more available to dental educators.

) carboxylic acid (C-SNARF-4) is employed to monitor extracellular pH in in vivo grown dental biofilms of unknown species composition. Upon exposure to glucose the dye is up-concentrated inside all bacterial cells in the biofilms; it is thus used both as a universal bacterial stain and as a marker......The pH in bacterial biofilms on teeth is of central importance for dental caries, a disease with a high worldwide prevalence. Nutrients and metabolites are not distributed evenly in dental biofilms. A complex interplay of sorption to and reaction with organic matter in the biofilm reduces...... the diffusion paths of solutes and creates steep gradients of reactive molecules, including organic acids, across the biofilm. Quantitative fluorescent microscopic methods, such as fluorescence life time imaging or pH ratiometry, can be employed to visualize pH in different microenvironments of dental biofilms...

Ceramics are very important in the science of dental biomaterials. Among all dental ceramics, zirconia is in evidence as a dental biomaterial and it is the material of choice in contemporary restorative dentistry. Zirconia has been applied as structural material for dental bridges, crowns, inserts, and implants, mostly because of its biocompatibility, high fracture toughness, and radiopacity. However, the clinical success of restorative dentistry has to consider the adhesion to different subs...

Good oral health is a fungamental component of pregnant women overall health and quality of life. To determine the proportion of dental services utilisation and the reasons for non utilisation among women receiving antenatal care at the Lagos State University Teaching Hospital (LASUTH). A cross-sectional study of all pregnant women receiving antenatal care in a Nigerian teaching hospital (LASUTH) between July and September 2008 was conducted. The study assessed the women's opinions on regular dental visits, dental visits during pregnancy, the frequency of utilization of oral health services before and during pregnancy and their reasons for non-attendance. Three hundred and forty two (342) pregnant women with age range 18 to 44 years (mean 30.37 +/- 4.5) participated in the study. Only 163 respondents (33.0%) reported ever visiting a dentist, 24 (7.0%) had done so just before or during the present pregnancy. Among the dental clinic attendees the commonest reason for attendance was pain (88 women or 53.9%). Majority (62%) of those who had never visited a dentist attributed their non-attendance to the absence of dental pain. There was a significant relationship between the respondent's age and the utilization of dental services (p dental services more often than their younger counterparts. Educational level and ethnic grouping were not significantly related to their use of dental services. A high proportion of women receiving antenatal care at LASUTH do not visit the dentist regularly. It is important to provide women in the reproductive age with information on the benefit of regular dental care especially during pregnancy.

To determine the prevalence of workplace violence in Oral healthcare centres against Nigerian dental professionals. A questionnaire-based cross-sectional survey of 175 randomly selected dental professionals working in Oral healthcare centres of University Teaching Hospitals in Southern Nigeria was conducted. The survey response rate was 78.9%. The respondents were dentists (58.0%), dental nurses (18.1%), dental technologists (12.3%), dental therapists (8.0%) and dental record officers (3.6%). The prevalence of violence in Nigerian Oral healthcare centres was 31.9%. There was no statistically significant difference in the prevalence of violence against dentist and dental auxiliaries. Violence was often associated with long waiting time (27.3%), cancellation of appointment (13.6%), outcome of patient's treatment (11.4%), alcohol intoxication (9.1%), psychiatric patient (6.8%,) patient's bill (4.5%) and others (27.3%). Non-physical violence in form of loud shouting (50.0%) threat (22.7%), sexual harassment (6.8%) and swearing (2.3%) constituted the majority while physical violence in form of bullying and hitting constituted the remaining 18.2%. The main perpetrators of the violence were patients (54.5%) and patient's relatives/friends (18.2%). The expressed impact of violence among the respondents include fear (18.2%), impaired job performance (15.9%), psychological problems (13.6%) and off duty (9.1%). No impact was declared by 43.2% of respondents. The prevalence of workplace violence in Oral healthcare centres against dental professionals in Southern Nigeria was significant and had a substantial effect on dental professionals' well-being thus necessitating urgent attention.
A high number of patients have one or more missing tooth and it is estimated that one in four American subjects over the age of 74 have lost all their natural teeth. Many options exist to replace missing teeth but dental implants have become one of the most used biomaterial to replace one (or more) missing tooth over the last decades. Contemporary dental implants made with titanium have been proven safe and effective in large series of patients. This review considers the main historical facts concerned with dental implants and present the different critical factors that will ensure a good osseo-integration that will ensure a stable prosthesis anchorage.

The objective of this research is to demonstrate the risks and consequences of exposure to dental X-ray. The methodology used was the survey of bibliographic literature on this matter. First, we tried to understand the operation and characteristics of dental X-rays. Afterwards, we tried to know about the risks that this procedure offers to workers and patients. And concluded with the consequences of such exposure. The results showed that dental x-rays only offer risks in prolonged exposure, can affect the worker or patient to pathologies such as cancer or a life-time decreased due to the stochastic effect. Therefore, radiological protection standards must be respected and practised. (author)

Dental amalgam has served as an excellent and versatile restorative material for many years, despite periods of controversy. The authors review its history, summarize the evidence with regard to its performance and offer predictions for the future of this material. The PubMed database was used initially; the reference list for dental amalgam featured 8641 articles and 13 publications dealing with recent advances in dental amalgam. A forward search was undertaken on selected articles and using some author names. For the present, amalgam should remain the material of choice for economic direct restoration of posterior teeth. When esthetic concerns are paramount, tooth-colored materials, placed meticulously, can provide an acceptable alternative. All alternative restorative materials and procedures, however, have certain limitations. PMID:21217947

A study is made of the dental implications of oral cancer, with a view to avoiding the complications that appear once oncological treatment is started. The study comprised a total of 22 patients diagnosed with oral cancer according to clinical and histological criteria in the Service of Maxillofacial Surgery (Dental Clinic of the University of Barcelona, Spain) during the period 1996-2005, and posteriorly treated in different hospital centers in Barcelona. Of the 22 patients diagnosed with oral cancer in our Service, the present study finally analyzed the 12 subjects who reported for the dental controls. As regards the remaining 10 patients, 5 had died and 5 could not be located; these subjects were thus excluded from the analysis. All of the smokers had abandoned the habit. The most common tumor location was the lateral margin of the tongue. None of the patients visited the dentist regularly before the diagnosis of oral cancer. T1N0M0 was the most common tumor stage. Surgery was carried out in 50% of the cases, while 8.4% of the patients received radiotherapy and 41.6% underwent surgery with postoperative radiotherapy. In turn, 66.6% of the patients reported treatment sequelae such as dysgeusia, xerostomia or speech difficulties, and one patient suffered osteoradionecrosis. Forty-one percent of the patients did not undergo regular dental controls after cancer treatment. As regards oral and dental health, 16.6% presented caries, and 50% had active periodontal disease. Protocols are available for preventing the complications of oral cancer treatment, and thus for improving patient quality of life. However, important shortcomings in the application of such protocols on the part of the public health authorities make it difficult to reach these objectives.
Full Text Available Since ages, human beings suffer from the dental problems. With the journey as time elapsed the person treating the teeth changed (i.e., from barbers and monks to present dentists, equipment changed (i.e., from bow drills to airotor and laser handpieces, materials changed (i.e., from ground mastic alum/honey to tooth colored composite and ceramics. There has been drastic change in treatment planning from extraction to the conservation of teeth and from manual restoration to computerized restorations computer-aided design/computer-aided manufacturing. Thus, this review is an attempt to have an insight into major milestones of the dental timeline.

To develop the Croatian version of the 41-item Dental Environment Stress questionnaire (DES) for stress assessment of dental students in both, preclinical and clinical years of study and to test its psychometric properties in Croatian dental student population. The English version of the 41-Item DES questionnaire was first translated into the Croatian language. Subsequently, it was set on the google drive and filled out by a total of 202 students from the School of Dental Medicine, University of Zagreb and 30 additional students from other Faculties. Students also assessed their overall level of stress on the Likert scale (1=no stress, 5=highest level of stress). Internal consistency was tested on 202 dental students; test-retest reliability on 30 dental students who filled out the same questionnaire twice; convergent validity on 202 dental students; and divergent validity on 202 dental students and 30 students from faculties not belonging to the biomedicine group. Internal consistency showed high Cronbach alpha coefficient (0.9) and test-retest reliability showed no significant difference (P>0.05) within the period of 14 days when stress level had not changed (vacation). Convergent validity was confirmed by the significant association between the DES summary scores and the self- perceived level of stress (Spearman's rho=0.881; P <0.001). Divergent validity was confirmed by significantly lower DES summary scores in students not belonging to the Biomedicine group (t=7.5, P<0.001). Excellent psychometric properties of the Croatian version of the DES questionnaire enable its utilization for assessment of stress level in Croatian dental students.

To evaluate the influence of dental visiting patterns on the dental status and Oral Health-related Quality of Life (OHQoL) of patients visiting the University Clinic of Salamanca (Spain). This cross-sectional study consisted of a clinical oral examination and a questionnaire-based interviewin a consecutive sample of patients seeking a dental examination. Patients were classified as problem-based dental attendees(PB) and regular dental attendees(RB). Clinical and OHQoL(OHIP-14 & OIDP)data were compared betweengroups. Pair-wise comparisons were performed and a Logistic Regression Model was fitted for predicting the Odds Ratio (OR) of being a PB patient. The sample was composed of 255 patients aged 18 to 87 years (mean age: 63.1 ± 12.7; women: 51.8%). The PB patients had a poorer dental status (i.e. caries, periodontal and prosthetic needs), brushed their teethless,and were significantly more impaired in their OHQoL according to both instruments.The logistic regression coefficients demonstrated that on average the OR of being a PB patient was high in this dental patient sample, but this OR increased significantly if the patient was a male (OR= 1.1-5.0) or referred pain-related impacts according to the OHIP and, additionally, the OR decreased significantly as a function of the number of healthy fillings and the number of sextants coded as CPI=0. Regular dental check-ups are associated with better dental status and a better OHQoL after controlling for potentially related confounding factors.
Full Text Available Abstract Background A growing body of literature describes the performance of dental fear questionnaires in various countries. We describe the psychometric properties of Greek versions of the Modified Dental Anxiety Scale (MDAS and the Dental Fear Survey (DFS in adult Greek patients. Methods Greek versions of the MDAS and DFS were administered to two samples of adult dental patients. In the first sample, 195 patients attending one of three private practice dental offices in a large city in Greece completed the questionnaires in the waiting room before dental treatment. After treatment, their dentists (who did not know how the patients had answered the questionnaire rated their anxiety during dental treatment. In the second sample, 41 patients attending a Greek university dental school clinic completed the questionnaire twice at two separate visits, in order to provide test-retest data. Cronbach's alpha was used to compute the internal consistencies, while Spearman's rho was used to compute the test-retest reliabilities. Construct validity was assessed by correlating the responses to the MDAS and DFS by Spearman's rho. Spearman's rho was also used to examine the criterion validities, by comparing the questionnaire responses with the dentists' ratings of anxiety. Results The internal consistencies for the MDAS were 0.90 and 0.92 in the two samples; for the DFS, the internal consistencies were 0.96 in both samples. The test-retest reliabilities were 0.94 for the MDAS and 0.95 for the DFS. The correlation between the two questionnaires was 0.89. The patients' responses to both questionnaires were significantly related to the dentists' ratings of their anxiety during dental treatment (both p values Conclusion The results indicate that the Greek versions of the MDAS and DFS have good internal consistencies and test-retest reliabilities, as well as good construct and criterion validities. The psychometric properties of the Greek versions of these

Dental agenesis is the most common developmental anomaly in humans, frequently associated with disorders in dental development and maturation. The purpose of this study is to determine radiographic variations in dental maturation in a group of Venezuelan children with dental agenesis. 1,188 panoramic radiographs, from healthy patients ages 5 to 12 years old were studied for agenesis of permanent teeth. Dental maturation was assessed by relative eruption and dental age according to Nolla, comparing children affected with dental agenesis to a stratified control group selected from the same population, excluding children with premature loss of primary teeth in the left quadrants and unclear radiographs. Descriptive analysis, and differences between means and medians (Student t test, Kruskall-Wallis p=0.05) were performed. Medians for Nolla stages were similar between groups, with delay in tooth formation in the agenesis group for second molars (pagenesis, with variable significance for tooth formation of studied teeth.

The aims of the present study were to evaluate the reliability and validity of the Malay version of the Modified Dental Anxiety Scale (MDAS), and to determine the prevalence of dental anxiety and associated factors in a Malaysian population. A Malay-language questionnaire with questions to elicit demographic and dental care-related information, and the Malay version of the MDAS, were administered to 455 patients at the dental outpatient clinics of the Hospital Universiti Sains Malaysia. Factor analysis and internal consistency statistics were generated. A test-retest of the questionnaire was performed with 30 participants. Cronbach's alpha was 0.854, indicating good internal consistency. Factor analysis yielded results showing good validity. Approximately 3.5% of the participants expressed the highest levels of anxiety. Dental anxiety was significantly higher among females than males. Age correlated inversely with dental anxiety. Individuals seeking dental care only if a problem appeared had significantly more anxiety than regular attendees. Patients who postponed treatment because of fear had significantly higher anxiety levels than those who delayed treatment for other reasons. Past adverse dental experience exacerbated dental anxiety. The Malay version of the MDAS had good reliability and validity. Anxiety levels found in the Malaysians studied were comparable to participants from other countries. © 2014 Wiley Publishing Asia Pty Ltd.

Objectives Clinical data on survival rates reveal that all-ceramic dental prostheses are susceptible to fracture from repetitive occlusal loading. The objective of this review is to examine the underlying mechanisms of fatigue in current and future dental ceramics. Data/sources The nature of various fatigue modes is elucidated using fracture test data on ceramic layer specimens from the dental and biomechanics literature. Conclusions Failure modes can change over a lifetime, depending on restoration geometry, loading conditions and material properties. Modes that operate in single-cycle loading may be dominated by alternative modes in multi-cycle loading. While post-mortem examination of failed prostheses can determine the sources of certain fractures, the evolution of these fractures en route to failure remains poorly understood. Whereas it is commonly held that loss of load-bearing capacity of dental ceramics in repetitive loading is attributable to chemically-assisted 'slow crack growth' in the presence of water, we demonstrate the existence of more deleterious fatigue mechanisms, mechanical rather than chemical in nature. Neglecting to account for mechanical fatigue can lead to gross overestimates in predicted survival rates. Clinical significance Strategies for prolonging the clinical lifetimes of ceramic restorations are proposed based on a crack-containment philosophy. PMID:24135295

Dental anxiety is still prevalent, despite advances in treatment, and affects the utilization of health care services. The purpose of this cross-sectional study was to determine if patients with different degrees of dental anxiety and pain undergoing emergency dental care have different stress reactions as measured by salivary cortisol. Seventy three patients completed the modified dental anxiety scale (MDAS), and described any previous dental traumatic experience. Their socio-demographic characteristics were also recorded. They also rated pain intensity on a 100 mm visual analogue scale (VAS). A saliva sample was collected before the procedure, and analyzed by enzyme immunoassay. Thirty patients were dentally anxious and forty one complained of pain. In this sample, dental anxiety was not related to gender, age, educational level and family income; however, a previous traumatic event was related to dental anxiety. There was no association between salivary cortisol concentrations and gender or dental anxiety. Patients with pain showed higher cortisol levels. When gathering patient information, the dentist should note patients' negative dental experiences in order to provide more effective, less traumatic treatment.

A workflow is defined as a predefined set of work steps and partial ordering of these steps in any environment to achieve the expected outcome. Few studies have investigated the workflow of providers in a dental office. It is important to understand the interaction of dental providers with the existing technologies at point of care to assess breakdown in the workflow which could contribute to better technology designs. The study objective was to assess electronic dental record (EDR) workflows using time and motion methodology in order to identify breakdowns and opportunities for process improvement. A time and motion methodology was used to study the human-computer interaction and workflow of dental providers with an EDR in four dental centers at a large healthcare organization. A data collection tool was developed to capture the workflow of dental providers and staff while they interacted with an EDR during initial, planned, and emergency patient visits, and at the front desk. Qualitative and quantitative analysis was conducted on the observational data. Breakdowns in workflow were identified while posting charges, viewing radiographs, e-prescribing, and interacting with patient scheduler. EDR interaction time was significantly different between dentists and dental assistants (6:20 min vs. 10:57 min, p = 0.013) and between dentists and dental hygienists (6:20 min vs. 9:36 min, p = 0.003). On average, a dentist spent far less time than dental assistants and dental hygienists in data recording within the EDR.
Full Text Available TP ChaturvediFaculty of Dental Sciences, Institute of Medical Sciences, Banaras Hindu University, Varanasi, IndiaAbstract: The oral cavity provides an ideal and unique environment for study of biological processes involving metallic dental aids. Dental materials within the mouth interact continually with physiological fluids. Oral tissues are exposed to a veritable bombardment of both chemical and physical stimuli as well as the metabolism of many species of bacteria; yet, for the most part, oral tissues remain healthy. The pH of saliva varies from 5.2 to 7.8. Teeth, restorations, or any prosthesis including dental implants in the oral cavity have to function in one of the most inhospitable environments in the human body. They are subject to larger temperature and pH variations than most other parts of the body. Corrosion, the graded degradation of materials by electrochemical attack, is of concern particularly when dental implants are placed in the hostile electrolytic environment provided by the human mouth. Allergic reactions may occur from the presence of ions produced from the corrosion of implants. The present article describes various manifestations of allergic reactions due to implant material in the oral cavity.Keywords: dental implant, allergy, titanium, corrosion

Modern dentistry and dental education in China were first introduced from abroad by Dr. Lindsay in 1907. However, advancements in the field of dental laboratory technology did not occur to the same degree in specialties such as prosthodontics and orthodontics. Since the 1990s, orders from abroad demanding dental appliances surged as the image of China as the "world's factory" strengthened. The assembly line model, in which technicians work like simple procedure workers, was rapidly applied to denture production, while the traditional education system and apprenticeship systems demonstrated little progress in these years. The lack of advancement in dental laboratory technology education caused insufficient development in China's dental technology industry. In order to alter the situation, a four-year dental laboratory technology undergraduate educational program was established in 2005 by West China School of Stomatology, Sichuan University (WCSS, SCU). This program was based on SCU's undergraduate education and WCSS's junior college education systems. The program introduced scientific methods in relevant subjects into laboratory technicians' training and made many improvements in the availability of trained faculty, textbooks, laboratory facilities, and curriculum.

The Athens University, School of Dentistry, accepted the challenge to organize the Dental Health Services in the Athens 2004 Olympic and Paralympic Games in order to provide the best quality of oral health services to the athletes, coaches, escort members and Olympic Village personnel. Data from the whole activity protocol of the Athens 2004 Games Dental Health Services - the reception, admission and treatment protocols, the facilities and the infrastructure, the number of cases treated per specialty and the experience gained - were recorded. During the Olympic Games, there were more than 1400 dental cases in more than 650 patients, elite athletes, escort members, coaches and staff of the Olympic Village. Among them 313 fillings, 100 root canal therapies, 57 mouthguards and 9 dental trauma cases were treated. During the Paralympic Games, there were more than 240 dental cases in more than 220 patients. Among them 73 fillings, 12 root canal therapies, 21 extractions and 3 dental trauma cases were treated. In such events, highly trained dentists are needed and if possible, specialized in operative dentistry or endodontics. The role of team dentist seems to be of great importance.

The purpose of this cross-sectional study was to evaluate the association between parents' dental anxiety (DA) and independent variables. One hundred sixty-eight dyads of parents and six- to 12-year-old children who were undergoing treatment at a university pediatric dentistry clinic were recruited. Two examiners evaluated parents' DA and oral health literacy (OHL) using the Brazilian version of Corah's dental anxiety scale and the Brazilian Rapid Estimate of Adult Literacy in Dentistry (BREALD-30), respectively. Children's DA was reported by parents through the dental anxiety question (DAQ). Demographic data was also collected. A single examiner used the decayed, missing, and filled permanent teeth and primary teeth (DMFT/dmft) indices to assess the children's oral health status. The data analysis involved univariate and multivariate Poisson regression. In the multivariate regression, higher levels of parents' DA were associated with a household income equal to or less than the Brazilian monthly minimum wage (prevalence ratio [PR]=4.9; 95 percent confidence interval [CI]=2.1 to 11.7) and a lower degree of OHL (PR=1.68; 95 percent CI=1.01 to 2.8). Associations between parents' DA and children's DA and DMFT/dmft index were not found. Parents' dental anxiety was related to a low household income and low oral health literacy.

The curriculum for graduating dental and dental hygiene students must prepare them to contribute to the improvement or maintenance of health for individual patient's and the public's health. The objective is to describe the background for and the process used to develop a core Dental Public Health Curriculum for such students. The process used was to solicit and review existing dental public health curriculum in dental and dental hygiene schools; review curriculum for other health professionals; identify the themes needed to frame the curriculum; select usable materials and identify gaps in existing curricular materials; and develop appropriate curriculum materials that would embody the competencies developed for undergraduate dental and dental hygiene education. Twenty-three topics were identified as embodying the eight competencies. Based on these topics, six courses, Principles of Dental Public Health, Evidence-Based Dentistry, Ethics and Dental Public Health, Dental Public Health Policy and Advocacy, Oral Health Promotion and Disease Prevention, and Oral Health Literacy and Dental Public Health, were prepared. Each course includes syllabus, PowerPoint presentations, student assignments and activities, instructor guide, and classroom discussion points. Depending on the hours available in the existing curriculum at the dental or hygiene school, lecture presentations and take home assignments/discussions may be used independently or in combination with presentations from other courses. In addition, individual discussions and activities may be used to integrate dental public health materials into other courses. A flexible curriculum is available at the AAPHD website to enable the incorporation of DPH topics into the curriculum. © 2015 American Association of Public Health Dentistry.

The aims of this study were to develop, implement, and evaluate a novel interprofessional standardized patient exercise (ISPE) with oral-systemic and interprofessional collaborative practice (IPCP) components. Dental students and doctor of nursing practice (DNP) students at one U.S. university participated in the simulation, which was primarily designed to test their teamwork skills. In spring 2014, DNP students worked in the dental clinics with dental students under the supervision of nursing and dental faculty members. To test the teamwork outcomes for both groups of students, a standardized patient (SP) scenario was designed to include multiple chronic medical diagnoses and an oral-systemic component. The exercise was filmed for later review. Outcomes measures included SP and student self-evaluations and faculty evaluation of student documentation. The primary outcome of interest from a dental standpoint was faculty evaluation of IPCP competencies derived from the Core Competencies of Interprofessional Collaborative Practice and were deemed to be observable by faculty when viewing the videotaped scenario. Eight teams of students participated with an SP trained in the scenario. Each team consisted of a DNP student, a fourth-year dental student, and a second-year dental student. All eligible students in the DNP class (n=20) and eight students from each dental class (approximately 110 each) participated. The results showed that the teams scored highest on the role/responsibilities subscale, indicating students were respectful of each other's roles and expertise and effectively engaged each other to develop strategies to meet the patient's needs. Scores on the three other subscales (values/ethics, interprofessional communication, and teams/teamwork) were also high. These findings appeared to support IPCP as a method to foster knowledge and respect for other roles and responsibilities, improve appreciation of teamwork, and encourage better communication among health

Anxiety about and fear of dental treatment have been recognized as sources of problems in the management of child dental patients. It has been suggested that some individuals who are fearful of or anxious about dental treatment have a constitutional vulnerability to anxiety disorders as is evidenced by the presence of multiple fears, generalized anxiety or panic disorders. Concerning the child population, maternal anxiety is considered to be a major factor affecting the behaviour of young children expecting dental intervention. The aim of the study was to the measure general anxiety of children undergoing dental intervention and to compare it with some personality characteristics, such as psychopathology, extroversion and neuroticism. The evaluated sample comprises 50 children (31 girls and 19 boys), randomly selected at the University Dental Hospital, Skopje. The mean age for girls was 11.4 (± 2.4) years, and for boys 10.7 (± 2.6) years. Two psychometric instruments were used: the General Anxiety Scale for Children (GASC) and the Eysenck Personality Questionnaire (EPQ). The study confirms the presence of a high anxiety level (evaluated with GASC) among all children undergoing dental intervention. It also confirmed differences in anxiety scores between girls and boys, girls having higher scores for anxiety. Personality characteristics (evaluated with EPQ) showed low psychopathological traits, moderate extroversion and neuroticism, but accentuated insincerity (evaluated with L scale). L scales are lower with increasing age, but P scores rise with age, which could be related to puberty. No correlation was found between personality traits (obtained scores for EPQ) and anxiety except for neuroticism, which is positively correlated with the level of anxiety. In the management of dental anxiety some response measures (psychological support, biofeedback, and relaxation techniques) are recommended.

Trained teams spent four days in 120 Ohio dental practices observing 3751 patient encounters with dentists and hygienists. Direct observation of practice characteristics, procedures performed, and how procedure and nonprocedure time was utilized during patient visits was recorded using a modified Davis Observation Code that classified patient contact time into 24 behavioral categories. Dentist, hygienist, and patient characteristics were gathered by questionnaire. The most common nonprocedure behaviors observed for dentists were chatting, evaluation feedback, history taking, and answering patient questions. Hygienists added preventive counseling. We distinguish between preventive procedures and counseling in actual dental offices that are members of a practice-based research network. Almost a third of the dentist’s and half of the hygienist’s patient contact time is utilized for nonprocedure behaviors during patient encounters. These interactions may be linked to patient and practitioner satisfaction and effectiveness of self-care instruction.Keywords: dental practice, dental practice core activities, direct observation of dental practice, Dental Davis Observation Code, dentist, hygienist patient behaviors

Full Text Available The application of ergonomics is critical so that you can get a suitable working environment for professional, it is safe, healthy and comfortable. The objective was to identify whether the dental students followed the principles of ergonomics during clinical visits, evaluating, through photographs, compliance with ergonomic principles applied in dental practice, and finally identify the most affected sites by RSI / WMSDs of students enrolled in the dental clinic of the Faculdade IMED. Snapshots were made and only considered the position of the student operator, the same taken by the researcher using the mobile device. For each clinical procedure were taken two photographs in hidden angles to the student operator so that it did not change its ergonomic position to be observed. After obtaining the photos, they were evaluated and classified in scores from 0 to 3 according to the adequacy of the work placement, and then inserted into Excel and later in a database (SPSS 15.0. The following work is a cross-sectional, observational study, they were conducted in dental clinics IMED college. Among the 66 respondents, 14 were male and 52 female. It was found that 57 (86,3% reported feeling pain somewhere in the body, being the most affected sites neck (36.4%, and consecutively lower back (30.3% and higher than the back (27.3%. The results of the 63 procedures performed by the photographic shots were classified as “inadequate” in 49 procedures, “partially adequate” in 12 and “impossible to evaluate” in 2 procedures. The research results have shown a high prevalence of musculoskeletal pain and do not follow the ergonomic principles, emphasizing the need for more attention to ergonomics of the students.

Odontophobia is a rather unique phobia with special psychosomatic components that impact on the dental health of odontophobic persons. It also has psychosocial components largely as a result of destruction of the teeth and subsequent embarrassment that can affect a person and cause a vicious cycle of dental fear. The phenomenon is facilitated by misunderstandings and myths generated by both patients and dentists. The most common reasons given in the literature for such strong fears of dental treatment are: 1) bad experiences in childhood for 85% of cases, 2) feeling of powerlessness and lack of control over personal emotional reactions and over the social situation in the dental chair, 3) social learning processes in which the image of the dentist is cast in a negative light by the mass media or by the person's relatives or friends and 4) that the person has other psychologic problems (in 20% of cases), such as serious phobias and/or neuroses. A strategy of researching and thus tackling the problem is presented which focuses on three essential targets that require studying and change: 1) the community at large and their image of the dentist, 2) the patient role and 3) the dentist role. Various model projects are presented along with their diagnostic systems. These are seen to focus in varying degrees on different elements of the target groups that effect the dentist-patient relationship but the need to come out into the community and make the social environment right for these patients is an important factor in all strategies.(ABSTRACT TRUNCATED AT 250 WORDS)

Hand dermatitis among dental personnel has been an issue in recent years. Dental personnel manually handle polymer materials which are known to irritate skin, and also cause allergy. In addition, dental personnel wash their hands frequently, and use latex gloves, and are therefore at risk to develop hand dermatitis. To survey the occurrence of hand dermatitis among dental personnel, questionnaires were sent to all dental teams (dentist + chair assistant) working in the two northern Swedish counties. Referents were; researchers, teachers, and secretaries from a university and high schools, from the same geographical area. The response rate was 76% for dental teams, and 66% for referents. The results show that male dentists reported a significantly higher prevalence of hand dermatitis than male reference. In contrast to chair assistants and referents, dentists (both male and female) reported a higher extent of hand dermatitis on the left than on the right hand. There was an association between hand dermatitis among dental personnel and; age, eczema in childhood, and hay fever but, not with; sex, asthma, frequent washing of the hands, and glove use. Whitening of the fingers increased with increasing age among dental personnel. Pricking was also associated with frequent glove use. Pricking of the fingers was associated with sex, and 3.5 times more common among female dental personnel than male dentists. Numbness of the fingers, and finger pain was reported by more dentists than chair assistants and referents.

The purpose of this study was to evaluated the diagnostic performance of the senior dental students for the proximal dental caries in intraoral radiographs and to compare it with the dental hospital residents, the reference group. It was also investigated the diagnostic performance according to the carious lesion depth. Thirty-five intraoral periapical and bitewing radiographs with 213 proximal surface included in this study were selected from the dental patients at Chonnam National University Hospital. The observers were 181 senior dental students from 5 dental schools and 40 dentists who were second year resident from 5 dental hospitals. They were asked to evaluate the presence ro the absence of the proximal dental caries. The results were as follows : 1. The mean of the hitting rate for the overall observers was 184.51 surfaces and the diagnostic accuracy was 86.62%. 2. The diagnostic performance of the sound proximal tooth surfaces was very high, i.e., 91.5% true negative rate and 8.5% false positive rate. 3. The diagnostic performance of the dentist group was higher than the student group (P<0.05). 4. The proximal dental caries perceptibility increased as the lesion depth increased significantly (P<0.001) except no difference between the carious lesion depth III and IV (P>0.001).
Full Text Available Background. Dentures and dental instruments are frequently encountered ingested foreign bodies. The aim of the present study was to assess the safety and efficacy of endoscopically removing ingested dental objects. Methods. Twenty-nine consecutive patients with 29 dental objects who were treated at the Niigata University Medical and Dental Hospital from August 2009 to December 2015 were retrospectively reviewed. Characteristics of the patients and the ingested dental objects, the clinical features and findings of radiological imaging tests, and outcomes of endoscopic removal were analyzed. Results. Patients’ mean age was 62.9±21.0 years. The ingested dental objects included 23 dentures (13 crowns, 4 bridges, 4 partial dentures, and 2 other dentures and 6 dental instruments. Twenty-seven upper gastrointestinal endoscopies and 2 colonoscopies were performed, and their success rates were 92.6% and 100%, respectively. There were 2 cases of removal failure; one case involved an impacted partial denture in the cervical esophagus, and this case required surgical removal. Conclusions. Endoscopic removal of ingested dentures and dental instruments is associated with a favorable success rate and acceptable complications. The immediate intervention and appropriate selection of devices are essential for managing ingested dental objects.

Background : This study aimed to evaluate whether income-related inequalities in access to dental care services exist in Japan. Methods : The subjects included beneficiaries of the National Health Insurance (NHI) in Chiba City, Japan, who had been enrolled from 1 April 2014 to 31 March 2015. The presence or absence of dental visits and number of days spent on dental care services during the year were calculated using insurance claims submitted. Equivalent household income was calculated using individual income data from 1 January to 31 December 2013, declared for taxation. Results : Of the 216,211 enrolled subjects, 50.3% had dental care during the year. Among those with dental visits, the average number of days (standard deviation) spent on dental care services per year was 7.7 (7.1). Low income was associated with a decreased rate of dental care utilization regardless of age and sex. However, there was a significant inverse linear association between the number of days spent on dental care services and income levels for both sexes. Conclusions : There were income-related inequalities in access to dental care services, regardless of the age group or sex, within the Japanese universal health insurance system.

Full Text Available It is very significant to know the bone quality of the jaws and structural changes in bone for treatment planning and prognosis in dental practice. It is also important to have detailed information about the bone structure (density, trabeculation, quality, volume for avoiding surprises during dental surgical procedures including dental implant surgery, graft applications, endodontic surgery, periodontal surgery. Osteoporosis is one of the diseases that cause low bone quality. It is a chronic, systemic, metabolic bone disease that affects the individual's quality of life. The earliest suggestion of an association between osteoporosis and oral bone loss was made in 1960. Osteoporosis-related changes in the jaw-bones are not different from the other bones of the body. It was known that oral bone loss to be a part of common skeletal osteoporosis and planned osteoporosis therapy to be effective in the prevention of oral bone loss. The effects of osteoporosis on the jaw-bones can be summarized as, decrease in bone mineral content and density, deterioration of trabecular structure, increased remodelation rate and osteoblastic activity, reduction in residual bone volume and cortical bone thickness.

To characterize the development of strength during the setting process of dental silver amalgam in the context of 'early strength' measurements for standards compliance testing in relation to patient instructions, and demonstrate the applicability of the Hertzian 'ball on disc' method. Sixteen dental silver amalgam products were tested using the 'ball on disc' protocol at 1, 2, 3, 4 and 24h after setting at 37°C in air. The mixed materials were packed into a tapered steel disc mold (10mm diameter, 3mm thick) resting on a glass surface, slightly overfilled and carved level with a sharp edge, then ejected at ∼10min and placed immediately into an incubator at 37°C. Testing was in Hertzian mode, using a 20mm steel ball, with the specimen resting on a disc of glass-filled polyamide (E=10GPa) at a cross-head speed of 0.2mm/min on a universal testing machine (E3000, Instron). The load at first crack was recorded, as was the number of radial cracks produced. Radial cracking into 2-5 pieces, in a clinically-relevant (non-explosive) mode was observed in all cases. Considerable variation in setting rate between products, as indicated by the development of load at failure with time, was found. The distribution of normalized failure load values overall was lognormal (Weibull was excluded). The RMS coefficient of variation overall was 12.4%. The ball-on-disc test provides a facile, relevant measure of the strength of dental silver amalgam, and is viable as a standards compliance test. Early strength testing at a minimum of 2h is suggested. Copyright © 2012 Academy of Dental Materials. Published by Elsevier Ltd. All rights reserved.

Full Text Available Abstract Background The Cognitive Vulnerability Model proposes that perceptions of certain characteristics of a situation are critical determinants of fear. Although the model is applicable to all animal, natural environment and situational fears, it has not yet been applied specifically to dental fear. This study therefore aimed to examine the association between dental fear and perceptions of dental visits as uncontrollable, unpredictable and dangerous. Methods The study used a clustered, stratified national sample of Australians aged 15 years and over. All participants were asked in a telephone interview survey to indicate their level of dental fear. Participants who received an oral examination were subsequently provided with a self-complete questionnaire in which they rated their perceptions of uncontrollability, unpredictability and dangerousness associated with dental visiting. Results 3937 participants were recruited. Each of the three vulnerability-related perceptions was strongly associated with the prevalence of high dental fear. In a logistic regression analysis, uncontrollability and dangerousness perceptions were significantly associated with high dental fear after controlling for age and sex. However, unpredictability perceptions did not have a statistically significant independent association with dental fear after controlling for all other variables. Conclusion Results are mostly consistent with the Cognitive Vulnerability Model of the etiology of fear, with perceptions of uncontrollability, unpredictability and dangerousness each showing a strong bivariate relationship with high dental fear prevalence. However, more extensive measures of vulnerability perceptions would be valuable in future investigations.

Serious medical emergencies are fortunately a rare occurrence in the dental practice environment; however, if an emergency situation is encountered a delay in treatment may result in potentially avoidable consequences. The risk of mortality or serious morbidity can be reduced by ensuring that basic emergency equipment and medications are in place, and that the dental team is appropriately trained in basic life support measures. This article aims to provide an overview of the basic emergency medications and equipment that should be present in dental practices, and to discuss specific responses to some of the more common adverse medical events that can present while providing dental treatment.

For many Americans the cost of dental services represents a barrier to receiving regular dental care and maintaining proper oral health. The recent growth of the dental insurance industry, however, may partly offset this price barrier among insureds. Our purpose is to examine the relationship between coinsurance and dental prices for 16 dental services among a sample of Pennsylvania Blue Shield (PBS) adult insureds. The dependent price measure is the annual average gross price paid for 16 specific preventive, restorative, periodontic, endodontic, prosthodontic, and surgical dental services. Independent variables in the price model include the insured's age, education, coinsurance rates, time costs, market area, non-wage income, oral health status, area dentist-population ratio and usual source of care. Data sources are 1980 PBS claims and coinsurance rate data and a mail survey of sampled insureds. OLS regression analysis reveals that the model's independent variables explain little dental price variation. No variable is consistently significant across services, but market area, coinsurance rates, and time costs alternately dominate across equations. These results suggest that, among adult insureds, coinsurance and time costs influence dental fees in a minority of dental services. Insurance reduces the patient's sensitivity to money price, and non-price factors correspondingly seem to become more important in patient search.

In Saudi Arabia, personal protective equipment must meet global standards for infection control, but the country’s Islamic legislature also needs to be taken into account. Aim: To assess uniform-related infection control practices of a group of dental students in a dental school in Saudi Arabia and compare the results with existing literature related to cross-contamination through uniforms in the dental field. Method: A questionnaire was formulated and distributed to dental students at King Abdulaziz University Faculty of Dentistry in Jeddah, Saudi Arabia, which queried the students about their uniform-related infection control practices and their methods and frequency of laundering and sanitizing their uniforms, footwear, and name tags. Results: There is a significant difference between genders with regard to daily uniform habits. The frequency of uniform washing was below the standard and almost 30% of students were not aware of how their uniforms are washed. Added to this, there is no consensus on a unified uniform for male and female students. Conclusion: Information on preventing cross-contamination through wearing uniforms must be supplied, reinforced, and emphasized while taking into consideration the cultural needs of the Saudi society.

This paper documents the experience of the University of British Columbia's Geriatric Dentistry Program (GDP) with emphasis on the dental treatment needs of patients during its first year of operation. The GDP provided access to dental care for residents of longterm care facilities, education for hospital staff concerning daily mouth care, education of dental students and an opportunity for research. The first year of clinical activity saw a small, yet significant, improvement in oral health for residents using the dental services. We hope that the outcomes of this new dental program for long-term care facilities will encourage dentists to provide care for this vulnerable population.

Dental informatics is comparatively a juvenile and new field that has noteworthy potential for supporting clinical care, research, education and management. This field utilizes computer science, information sciences and the application of same to espouse dentistry. However, in the under-developed and developing countries almost most of the dentists are unacquainted about dental informatics, its goals, what it is capable of achieving and by what means they can get involved into it. Despite of emerging advances, certain conflicts also go along with it such as, professional under representation, security issues of the stored information due to universal access to computers high speed internet connections. Endnote software was used as resource material to collect literature which was carefully arranged in a synchronized way. Hence, the purpose of this review was to give an overall scenario of dental informatics, its applications, challenges and recommendations for further enhancement in this area.

Summary Background A workflow is defined as a predefined set of work steps and partial ordering of these steps in any environment to achieve the expected outcome. Few studies have investigated the workflow of providers in a dental office. It is important to understand the interaction of dental providers with the existing technologies at point of care to assess breakdown in the workflow which could contribute to better technology designs. Objective The study objective was to assess electronic dental record (EDR) workflows using time and motion methodology in order to identify breakdowns and opportunities for process improvement. Methods A time and motion methodology was used to study the human-computer interaction and workflow of dental providers with an EDR in four dental centers at a large healthcare organization. A data collection tool was developed to capture the workflow of dental providers and staff while they interacted with an EDR during initial, planned, and emergency patient visits, and at the front desk. Qualitative and quantitative analysis was conducted on the observational data. Results Breakdowns in workflow were identified while posting charges, viewing radiographs, e-prescribing, and interacting with patient scheduler. EDR interaction time was significantly different between dentists and dental assistants (6:20 min vs. 10:57 min, p = 0.013) and between dentists and dental hygienists (6:20 min vs. 9:36 min, p = 0.003). Conclusions On average, a dentist spent far less time than dental assistants and dental hygienists in data recording within the EDR. PMID:27437058
Full Text Available Background. Dental students have reported a high prevalence of psychological stress and the causes are associated with the challenging dental environmental and demographic factors. This study aimed to conduct a preliminary investigation on dental students’ stress status, using a sample of first-to-third-year Bachelor of Dental Surgery students in an Australian university. Special interests included causes of dental environmental stress and access to help services. Methods. A sample of 145 students was surveyed with a modified Dental Environmental Survey and Depression Anxiety Stress Scale in 2014. The participants’ demographic information was also collected. Results. The response rate was 95.4%. Second-year (P = 0.042, third-year (P < 0.001 and employed students (P = 0.027 were more likely to report stress resulting from transition to clinical learning. Third-year students were more often stressed about communicating and approaching staff (P = 0.023 as well as different opinions between staff (P < 0.001 and reduced holidays (P < 0.001. Students that were younger than 21 years of age (P = 0.001, that were first years (P < 0.001, and that were not in a relationship (P = 0.010 more often found difficulty of course work stressful. Students who were not in a relationship more often considered learning manual dexterity a source of stress (P = 0.034. Students previously seeking professional help were more likely to be stressed (P = 0.010. Conclusion. Causes of dental environment stress varied among years of study and demographic backgrounds. Professional support to stressed students should be enhanced. Further investigation is indicated.

The purpose of this study was to investigate the oral and dental findings in children with Fanconi anemia (FA). The study included 26 FA patients who came to the hospital (Hacettepe University Faculty of Medicine, Pediatric Hematology Unit) from the central region of Anatolia (17 [65%] mole, 9 [35%] female; mean age = 10.0 +/- 5.2 years (range = 2-18; median = 9 years]). Oral and radiological examinations and salivary collection were performed at the Department of Pediatric Dentistry of Hacettepe University Faculty of Dentistry. Among 26 FA children: (a) 16 (62%) had never visited a dentist; (b) 6 (23%) had visited a dentist once; and (c) 4 (15%) had visited a dentist regularly. Furthermore: (a) only 5 children (19%) brushed their teeth regularly; (b) 7 (27%) had never brushed their teeth previously; and (c) the other 14 (54%) had brushed their teeth rarely. The prevalence of dental caries was 35% in this study's patients. Gingival examination revealed that 9 (35%) children had gingivitis and the other 17 (65%) had normal gingival health status. Examination of the oral cavity revealed that: (a) 3 children (12%) had a coated tongue; and (b) 1 (4%) had papillary atrophy. No leukoplakia or other precancerous lesion was detected in this patient group. Salivary flow rate was less than 0.7 ml/minute in 56% of the patients. No patients had a salivary pH less than 5. Salivary buffering capacity of less than 5, however, was detected in 5 patients (33%). Radiological evaluation revealed that the most common congenital dental abnormalities were: (1) microdontia (44%); (2) congenitally missing teeth (26%); (3) transposition (9%); and (4) supernumerary teeth (4%). These results demonstrate that poor oral hygiene, dental decay, gingivitis, and congenital dental abnormalities--including generalized microdontia, supernumerary teeth, transposition, and congenitally missing teeth--are common oral and dental findings in this group of Turkish children with Fanconi anemia.

In England and Scotland, dental extraction is the single highest cause of planned admission to the hospital for children under 11 years. Traditional dental services have had limited success in reducing this disease burden. Interventions based on motivational interviewing have been shown to impact positively dental health behaviours and could facilitate the prevention of re-occurrence of dental caries in this high-risk population. The objective of the study is to evaluate whether a new, dental nurse-led service, delivered using a brief negotiated interview based on motivational interviewing, is a more cost-effective service than treatment as usual, in reducing the re-occurrence of dental decay in young children with previous dental extractions. This 2-year, two-arm, multicentre, randomised controlled trial will include 224 child participants, initially aged 5 to 7 years, who are scheduled to have one or more primary teeth extracted for dental caries under general anaesthesia (GA), relative analgesia (RA: inhalation sedation) or local anaesthesia (LA). The trial will be conducted in University Dental Hospitals, Secondary Care Centres or other providers of dental extraction services across the United Kingdom. The intervention will include a brief negotiated interview (based on the principles of motivational interviewing) delivered between enrollment and 6 weeks post-extraction, followed by directed prevention in primary dental care. Participants will be followed up for 2 years. The main outcome measure will be the dental caries experienced by 2 years post-enrollment at the level of dentine involvement on any tooth in either dentition, which had been caries-free at the baseline assessment. The participants are a hard-to-reach group in which secondary prevention is a challenge. Lack of engagement with dental care makes the children and their families scheduled for extraction particularly difficult to recruit to an RCT. Variations in service delivery between sites have

Teeth are colonized by oral bacteria from saliva containing more than 700 different bacterial species. If removed regularly, the dental biofilm mainly comprises oral streptococci and is regarded as resident microflora. But if left undisturbed, a complex biofilm containing up to 100 bacterial species at a site will build up and may eventually cause development of disease. Depending on local ecological factors, the composition of the dental biofilm may vary considerably. With access to excess carbohydrates, the dental biofilm will be dominated by mainly gram-positive carbohydrate-fermenting bacteria causing demineralization of teeth, dental caries, which may further lead to inflammation and necrosis in the pulp and periapical region, i.e., pulpitis and periapical periodontitis. In supra- and subgingival biofilms, predominantly gram-negative, anaerobic proteolytic bacteria will colonize and cause gingival inflammation and breakdown of supporting periodontal fibers and bone and ultimately tooth loss, i.e., gingivitis, chronic or aggressive periodontitis, and around dental implants, peri-implantitis. Furthermore, bacteria from the dental biofilm may spread to other parts of the body by bacteremia and cause systemic disease. Basically, prevention and treatment of dental biofilm infections are achieved by regular personal and professional removal of the dental biofilm. © 2017 APMIS. Published by John Wiley & Sons Ltd.
The importance of the introduction of dental implants can only be understood when the historical context is clarified. In the past, the main treatment carried out by dentists consisted of filling or, in unfortunate cases, removal of painful teeth. Only since the introduction of dental implants did

We make a review of the factors contributing to microleakage around dental restorations and the biological effects that this produces. We also make an evaluation of the existing methods for its research. We analize the behaviour of the different restorative materials, in relation to microleakage, and we set the rules to minimize this inevitable event that affects so much the longevity of dental restorations.

Anxiety is a significant issue in the dental care of adults and children. Dental anxiety often leads to avoidance of dental care which may result in significant deterioration of oral and dental health. Non-pharmacological anxiety management interventions such as music listening are increasingly used in dental care. Although efficacy for music's anxiolytic effects has been established for pre-operative anxiety, findings regarding the use of music listening for dental anxiety are inconclusive, especially for children. The use of music for passive distraction may not be adequate for children and highly anxious adults. Instead, interventions offered by a trained music therapist may be needed to optimize music's anxiolytic impact. Music therapy interventions are individualized to the patient's presenting needs and geared at enhancing patients' active engagement in the management of their anxiety. Interventions may include (i) active refocusing of attention, (ii) music-guided deep breathing, (iii) music-assisted relaxation, and (iv) music-guided imagery. In addition, music therapists can teach patients music-based anxiety management skills prior to dental treatments, offer them the opportunity to express emotions related to the upcoming procedure, and help them gain a sense of control and safety. Clinical guidelines for the use of music listening by dental practitioners are offered. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Forensic odontology (dental forensics can provide useful evidence in both criminal and civil cases, and therefore remains a part of the wider discipline of forensic science. As an example from the toolbox of forensic odontology, the practice and experience on bitemark analysis is reviewed here in brief. The principle of using visible bitemarks in crime victims or in other objects as evidence is fundamentally based on the observation that the detailed pattern of dental imprints tend to be practically unique for each individual. Therefore, finding such an imprint as a bitemark can bear a strong testimony that it was produced by the individual that has the matching dental pattern. However, the comparison of the observed bitemark and the suspected set of teeth will necessarily require human interpretation, and this is not infallible. Both technical challenges in the bitemarks and human errors in the interpretation are possible. To minimise such errors and to maximise the value of bitemark analysis, dedicated procedures and protocols have been developed, and the personnel taking care of the analysis need to be properly trained. In principle the action within the discipline should be conducted as in evidence-based dentristy, i.e. accepted procedures should have known error rates. Because of the involvement of human interpretation, even personal performance statistics may be required from legal expert statements. The requirements have been introduced largely due to cases where false convictions based on bitemark analysishave been overturned after DNA analysis.DOI: 10.14693/jdi.v15i2.76
To determine dental eruption sequences of extant platyrrhines, 367 mandibles and maxillae of informative juvenile specimens from all 16 genera were scored for presence of permanent teeth including three intermediate eruption stages following Harvati (Am J Phys Anthropol 112 (2000) 69-85). The timing of molar eruption relative to that of the anterior dentition is variable in platyrrhines. Aotus is precocious, with all molars erupting in succession before replacement of any deciduous teeth, while Cebus is delayed in M2-3 eruption relative to I1-2. Callitrichines have a distinct tendency toward delayed canine and premolar development. Platyrrhine eruption sequences presented here show some evidence of conformity to Schultz's Rule, with relatively early replacement of deciduous dentition in "slower"-growing animals. The relationship of dental eruption sequences to degree of folivory, body mass, brain mass, and dietary quality is also examined. The early eruption of molars relative to anterior teeth in Pithecia, Chiropotes, and Cacajao, in comparison to genera such as Ateles, Lagothrix, and Alouatta, showing relatively later eruption of the molars, appears to be consistent with current phylogenetic hypotheses. Schultz (Am J Phys Anthropol 19 (1935) 489-581) postulated early relative molar eruption as the primitive dental eruption schedule for primates. The extremely early molar eruption of Aotus versus Callicebus (where both incisors erupt before M2 and M3, with M3 usually last) may lend support to the status of Aotus as a basal taxon. The early relative molar eruption of the fossil platyrrhine species Branisella boliviana is also consistent with this hypothesis (Takai et al.: Am J Phys Anthropol 111 (2000) 263-281).

With the advent of nanotechnology, an opportunity exists for the engineering of new dental implant materials. Metallic dental implants have been successfully used for decades, but they have shortcomings related to osseointegration and mechanical properties that do not match those of bone. Absent the development of an entirely new class of materials, faster osseointegration of currently available dental implants can be accomplished by various surface modifications. To date, there is no consensus regarding the preferred method(s) of implant surface modification, and further development will be required before the ideal implant surface can be created, let alone become available for clinical use. Current approaches can generally be categorized into three areas: ceramic coatings, surface functionalization, and patterning on the micro- to nanoscale. The distinctions among these are imprecise, as some or all of these approaches can be combined to improve in vivo implant performance. These surface improvements have resulted in durable implants with a high percentage of success and long-term function. Nanotechnology has provided another set of opportunities for the manipulation of implant surfaces in its capacity to mimic the surface topography formed by extracellular matrix components of natural tissue. The possibilities introduced by nanotechnology now permit the tailoring of implant chemistry and structure with an unprecedented degree of control. For the first time, tools are available that can be used to manipulate the physicochemical environment and monitor key cellular events at the molecular level. These new tools and capabilities will result in faster bone formation, reduced healing time, and rapid recovery to function.

Full Text Available OBJECTIVE: Sexual harassment is unlawful in all work and educational environments in most nations of the world. The goals of this study were to describe the sexual harassment prevalence and to evaluate the experiences and attitudes of undergraduate students in one dental school in Brazil. MATERIAL AND METHODS: An 18-item questionnaire was administered to 254 dental students with a completion rate of 82% (208. Students were requested to respond to questions about their background and academic level in dental school, their personal experiences with sexual harassment and their observation of someone else being sexually harassed. Bivariate statistical analyses were performed. RESULTS: Fifteen percent of the students reported being sexually harassed by a patient, by a relative of a patient or by a professor. Male students had 3 times higher probability of being sexually harassed than female student [OR=2.910 (1.113-7.611]. Additionally, 25.4% of the students reported witnessing sexual harassment at the school environment. The majority of students did not feel professionally prepared to respond to unwanted sexual behaviors. CONCLUSION: These findings demonstrate that sexual harassment can occur in a dental school setting. There is a need for ongoing sexual harassment education programs for students and university staff. Increased knowledge of sexual harassment during graduation can better prepare dental professionals to respond to sexual harassment during their practice.

Investigating career motivations and intentions of dental students provides a better understanding of their role in society and contributes to the debate on dental education and practices. This study describes the profile, career choice motivations, and career intentions of Brazilian dental students and evaluates factors related to these choices. A cross-sectional study was carried out among dental students from three Brazilian public universities (N=915), with a response rate of 83.7 percent. Students (N=766) responded to a self-administered questionnaire about sociodemographic factors, reasons for choosing dentistry as a career, and future career intentions. Job conception was found to be the main reason for choosing dentistry as a profession. Most students intended to become specialists and work in both the public and private sectors simultaneously. Female students (OR 2.23, 95 percent CI=1.62-3.08), low-income students (OR 1.86, 95 percent CI=1.10-3.13), and students beginning their program (OR 1.87, 95 percent CI=1.22-2.85) were more likely to work in the public and private sectors simultaneously than other types of students. This study suggests that choice of career and career plans are influenced by factors related to the students' characteristics and their conception of the profession. The opportunity to combine private and public dental practice may be viewed as a way to achieve income and job security.

Full Text Available Dental implant has become a fast developing and dynamic field in dental practice. It is acknowledged as a predictable treatment modality with high clinical success rates. Conventional fixed prostheses are no longer considered to be the first choice of treatment for replacing a missing tooth. Despite the increasing number of patients requesting dental implant treatments, there are only some clinicians who are offering implant therapy in their daily practice. The International team for Implantology described a straightforward case as a simple case such as implant placements in adquate soft and hard tissue conditions and single-tooth restorations in a non-aesthetic zone. A review of the current literature discussed the implementation of implant dentistry in universities worldwide into their curriculum for both undergraduate and postgraduate programs in general dentistry. The European consensus in implant dentistry education concluded that it is desirable to include the surgical technique for implant placement for straightforward cases into the dental curriculum. The levels and limitations to which the various aspects of implant dentistry and related skills are taught to be determined by the academic community. This review aimed at promoting awareness amongst dental practitioners and institutions in Indonesia of the shifting treatment paradigm in the maangement of a missing tooth. Hence clinicians will be able to include implant dentistry in the treatment planning of their patients and also undertake a significant part in the execution of such treatments.
Full Text Available Purpose: The aim of the present study was to investigate the prevalence of dental anomalies in a Turkish population according to the gender and age. Materials and Methods: A retrospective study was performed using panoramic radiographs of 2025 patients (885 males and 1140 females ranging in age from 9 to 35 (mean age 25.61±10.04 years attending Department of Oral Radiology, University of Istanbul, Faculty of Dentistry. These patients were examined to determine the presence of developmental dental anomalies involving hypodontia, hyperdontia, microdontia, taurodontism and other root anomalies. The incidence of these anomalies were assessed according to the gender and age. Results: Among the 2025 subjects, a total of 96 individuals (42 males and 54 females showed at least one of the selected dental anomalies (4.74%. Tooth agenesis was the most common dental abnormality (1.77% followed by taurodontism (1.18%, hyperdontia (0.79%, microdontia (0.54% and root anomalies (0.44%, respectively. Conclusion: Tooth agenesis is the most common developmental dental anomaly in the studied Turkish population followed by taurodontism.
Two main classes of material are involved, the glass-ionomer cements and the composite resins. This investigation describes the way they are bonded to the tooth and highlights their differences. Glass ionomers develop a zone of interaction with the tooth as they age which ultimately gives an extremely strong bond, and results in excellent retention rates. By contrast, bonding of composite resins is more complicated and possibly less effective, though these materials have better wear resistance and better aesthetics than glass ionomers. Assessment of bond durability is difficult. This is because a dental restorative can fail by a number of mechanisms apart from de bonding: for example, through wear or fracture
The American Dental Dream-the cultural desire for straight, white teeth-is difficult, if not impossible, for poor and working-class people to achieve. Using ethnographic fiction, autoethnography, poetry, and qualitative interviewing, I brush away the taken-for-granted assumptions about teeth. I explore the personal, relational, and structural consequences of this cultural desire, and show how social class writes itself on our bodies. I write these culture-centered teeth tales to show how one might cope with their teeth.

The increasing complexity of the dental office environment influences productivity and workflow for dental clinicians. Advances in technology, and with it the range of products needed to provide services, have led to sprawl in operatory setups and the potential for awkward postures for dental clinicians during the delivery of oral health services. Although ergonomics often addresses the prevention of musculoskeletal disorders for specific populations of workers, concepts of workflow and productivity are integral to improved practice in work environments. This article provides suggestions for improving workflow and productivity for dental clinicians. The article applies ergonomic principles to dental practice issues such as equipment and supply management, office design, and workflow management. Implications for improved ergonomic processes and future research are explored.

To examine the attitudes of dental students and social policy students towards learning disabilities in order to identify whether attitudinal differences exist and to suggest recommendations in the dental undergraduate curriculum commensurate with Government legislation in the United Kingdom. A cross-sectional survey of all undergraduate dental students at Queen's University, Belfast and all undergraduate social policy students at University of Ulster. A convenience sample of all undergraduate dental and social policy students was obtained. The students completed a questionnaire to assess attitude towards learning disability. The data were analysed using Cronbach's alpha, Student's t-test and analysis of variance (one-way fixed effect model). The level of statistical significance was set at 5%. The response rate was 83% for dental students and 97% for social policy students. Dental students had significantly lower mean scores and hence less favourable attitudes to learning disability compared with social policy students. Female dental students had significantly higher mean scores and hence more favourable attitudes to learning disability compared with male students. The findings show that dental undergraduates compared with social policy students had less favourable attitudes towards those with learning disability. Dental students should receive training in learning disability and undergraduate programmes should be conceptualised as a spiral curriculum. It is proposed that social policy theory should be introduced into undergraduate dental curricula, that early exposure to learning disability in a community setting should be incorporated into the first undergraduate years and in later undergraduate clinical years students should treat patients with learning disability in order to promote experiential learning and reflective practice.

This aim of this study was to investigate the differences between patients with and without a treatment history of dental implants by use of a questionnaire survey in order to determine the information that is required for patients undergoing dental implants. The questionnaires were given to 4512 patients who visited the Tokyo Medical and Dental University Hospital for oral implants between January 2012 and December 2014, and 2972 (66%) valid questionnaires were collected. There were 857 patients with a treatment history of dental implants and 2115 patients without. "Preservation of an adjacent tooth" was the reason that 32% of these patients chose implant therapy, and the patients without treatment history were significantly higher than the patients with one. Significantly, more patients without a treatment history of dental implants selected the after-effects of surgery and pain after surgery as their main concerns for implant therapy compared to those with a treatment history. In the question "Pain after surgery," the patients without treatment history did not know significantly lower than the patients with one. Patients without a treatment history of dental implants placed more importance on the preservation of healthy teeth. Because patients, in particular those without a treatment history of dental implants, are anxious about surgery, we should provide them with more information on treatment than we already do and explain the risks of treatment to them. To keep the credence between doctors and patients, informed consent and patient education on treatment are six important concerns. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To examine the influence of dental students' gender and ethnicity on their perceptions of dental nurses' duties and upon their communication and working styles when interacting with dental nurses (DNs). A survey of clinical dental students attending Queen's University Belfast and University of Leeds. Students were invited to complete the 34 item Communication and Working Styles Questionnaire. The questionnaire assessed the students' perceptions of the duties of a DN and the students' communication and working styles. Factor analysis revealed two communication and working styles which were friendly and difficult styles, respectively. Two hundred and forty-eight students participated giving a response rate of 88%: 58% were female and 30% of students from Leeds were from various ethnic minority groups. The students' perceptions as to the duties of a DN were affected by university attended and ethnicity. The majority of students used friendly communication styles. The type of style used was determined by university attended, gender and ethnicity. Male students had higher mean scores for friendly working styles whereas students from minority ethnic groups had higher mean scores for gender-related communication style. Female students and students from minority ethnic groups had higher mean scores for items relating to teamwork. This survey illustrates the different communication and working styles used by male and female and dental students from different ethnic backgrounds when interacting and working with DNs.

Dental morphology is a useful resource in archaeology, anthropology and paleontology, due to its genetic determination. Teeth are a material of high durability and stability. This work aims to study the dental morphology and test the Portuguese and European biological affinities of an undocumented mandibular sample, through comparison with global and Iberian samples. The dental traits in 163 mandibles (kept at the Museum of Natural History of the University of Oporto, Portugal) were scored using a standardized methodology (ASUDAS: Arizona State University Dental Anthropology System) and compared to other world-wide and Iberian samples through Principal Components (PCA) and Mean Measure of Divergence analyses. The undertaken quantitative and statistical tests demonstrated the unknown sample to be closer to the Coimbra Portuguese sample in all three comparisons. This suggests this undocumented mandibular sample is possibly of Portuguese 19 th /20 th century origin.

The purpose of this study was to determine the level of glycemic control in dental patients with diabetes upon admission to a dental school clinic. One hundred patients (mean age: 57.7 years) of the Oral Diagnosis-Admissions Clinic at the University of Minnesota School of Dentistry, Minneapolis, Minnesota, with diabetes mellitus were chosen as subjects. Fasting blood glucose was measured using a portable blood glucose monitoring device as a part of their initial dental examination. Twenty-eight of the 100 patients were found to be hyperglycemic (> or = 126 mg/dl; 174.8 +/- 40.8 mg/dl; mean +/- SEM); 2 patients were found to be hypoglycemic (diabetes in the cohort, 3 (37.5%) were very hyperglycemic, with fasting blood glucose levels > 250 mg/dl. This is important information for dental practitioners because patients with diabetes may not be under good glycemic control, and dentists may have to take special precautions before, during, and after treatment. This paper reviews the pathogenesis of diabetes, the detection of patients with undiagnosed or poorly controlled diabetes, and the management of patients with diabetes during dental treatment.

Dental caries and trauma are the most common oral health problems for many decades. There is need for prevalence data to analyze the nature of the problems and to take necessary steps in improving public health. To assess the prevalence of dental caries and traumatic dental injuries among schoolchildren of age 6 to 12 years in Bhopal city. Cross-sectional study design was selected. Universal sampling method was followed in this study. A total of 1,204 children were examined. The distribution of samples was done based on age, gender, residing area, and type of school. Data were collected and statistically evaluated under chi-square test and analysis of variance. The overall caries experience (73.17%) was found to be higher than that of traumatic injury experience (20.9%). There was age-related correlation between age and decay, missing, and filled teeth score. Since most injuries occur at home or at school, educating the individual is the key that will have a great impact on the prognosis of traumatic injuries. Also good food habits need to be instilled in children from a tender age with the help of parents, which is the ultimate solution to fight caries.

Among the challenges leaders in dental and allied dental education have faced in recent years is a shortage of well-qualified faculty members, especially in some specialty areas of dentistry. One proposed solution has been the use of technology. At the University of Missouri-Kansas City School of Dentistry, the departure of a faculty member who taught the highly specialized content in oral histology and embryology provided the opportunity to implement distance delivery of that course. The course is taught once a year to a combined group of dental and dental hygiene students. Previous to spring semester of 2009, the course was taught using traditional face-to-face, in-class lectures and multiple-choice examinations. During the spring semesters of 2009, 2010, and 2011, the course was taught using synchronous and asynchronous distance delivery technology. Outcomes for these courses (including course grades and performance on the National Board Dental Examination Part I) were compared to those from the 2006, 2007, and 2008 courses. Students participating in the online hybrid course were also given an author-designed survey, and the perceptions of the faculty member who made the transition from teaching the course in a traditional face-to-face format to teaching in an online hybrid format were solicited. Overall, student and faculty perceptions and student outcomes and course reviews have been positive. The results of this study can provide guidance to those seeking to use technology as one method of curricular delivery.

The aim of this study was to assess general dental practitioners' knowledge of dental radiography and radiation protection in order to alert the Belgian authorities and dental professional societies. Prior to attending a postgraduate course on intraoral radiology, general dental practitioners in Flanders, Belgium, were asked to fill in a questionnaire regarding the radiological equipment and the techniques they used for intraoral radiography. The availability and type of dental panoramic equipment were also assessed. A total of 374 questionnaires were available for this study. 15% of the attendants used radiographic equipment that was more than 27 years old and 43% reported equipment that operated with a clockwork timer. 32% and 75% respectively had no idea what the kV or mA settings were on their intraoral equipment. 5% were unaware which cone geometry or geometric technique (paralleling or bisecting angle technique) they were using. 81% claimed to be using a short cone technique. 47% did not know what collimation meant, whereas 40% stated that they were using circular collimation. 38% used digital intraoral image detectors (63% were photostimulable storage phosphorplate (PSPP)), but 16% were not sure about the type of sensor they were using (PSPP or solid-state sensors). 61% also had dental panoramic equipment available, 25% of which was digital (10% charge coupled device (CCD) and 15% PSPP). These results clearly indicate the need for continued education on this subject. The latter is an important signal to Belgian authorities and dental professional societies.

Policy has recently changed on provision of dental general anaesthetic services in England. The aim of this study was to investigate general dental practitioners' views about dental general anaesthetics, the reduction in its availability and the impact on care of children with toothache. Qualitative study using semi-structured interviews and clinical case scenarios. General dental practitioners providing NHS services in the North West of England. 93 general dental practitioners were interviewed and 91 answered a clinical case scenario about the care they would provide for a 7-year-old child with multiple decayed teeth presenting with toothache. Scenario responses showed variation; 8% would immediately refer for general anaesthesia, 25% would initially prescribe antibiotics, but the majority would attempt to either restore or extract the tooth causing pain. Interview responses also demonstrated variation in care, however most dentists agree general anaesthesia has a role for nervous children but only refer as a last resort. The responses indicated an increase in inequalities, and that access to services did not match population needs, leaving some children waiting in pain. Most general dental practitioners support moving dental general anaesthesia into hospitals but some believe that it has widened health inequalities and there is also a problem associated with variation in treatment provision. Additional general anaesthetic services in some areas with high levels of tooth decay are needed and evidence based guidelines about caring for children with toothache are required.

To explore a method of constructing universal 3-dimensional (3D) colorized digital dental model which can be displayed and edited in common 3D software (such as Geomagic series), in order to improve the visual effect of digital dental model in 3D software. The morphological data of teeth and gingivae were obtained by intra-oral scanning system (3Shape TRIOS), constructing 3D digital dental models. The 3D digital dental models were exported as STL files. Meanwhile, referring to the accredited photography guide of American Academy of Cosmetic Dentistry (AACD), five selected digital photographs of patients'teeth and gingivae were taken by digital single lens reflex camera (DSLR) with the same exposure parameters (except occlusal views) to capture the color data. In Geomagic Studio 2013, after STL file of 3D digital dental model being imported, digital photographs were projected on 3D digital dental model with corresponding position and angle. The junctions of different photos were carefully trimmed to get continuous and natural color transitions. Then the 3D colorized digital dental model was constructed, which was exported as OBJ file or WRP file which was a special file for software of Geomagic series. For the purpose of evaluating the visual effect of the 3D colorized digital model, a rating scale on color simulation effect in views of patients'evaluation was used. Sixteen patients were recruited and their scores on colored and non-colored digital dental models were recorded. The data were analyzed using McNemar-Bowker test in SPSS 20. Universal 3D colorized digital dental model with better color simulation was constructed based on intra-oral scanning and digital photography. For clinical application, the 3D colorized digital dental models, combined with 3D face images, were introduced into 3D smile design of aesthetic rehabilitation, which could improve the patients' cognition for the esthetic digital design and virtual prosthetic effect.

Full Text Available Contemporary tendencies in dentistry are based on the concept of maximal protection of healthy tooth tissues. Caries removal has been done traditionally with mechanical rotary instruments that are fast and precise. However, conventional cavity preparation has potential adverse effects to the pulp due to heat, pressure and vibrations. Moreover, drilling often causes pain and requires local anaesthesia, and these procedures are frequently perceived as unpleasant. Etiology, development and prevention of dental caries are better understood today and new restorative materials that bond micromechanically and/or chemically to dental tissues have been introduced. Thus, development of a new, less destructive caries removal technique is allowed. In the last decades, many alternative methods have been introduced in an attempt to replace rotary instruments. These are claimed to be efficient and selective for diseased tissues and to offer comfortable treatment to the patients. New methods include air abrasion, air polishing, ultrasonic, polymer burs, enzymes, systems for chemo-mechanical caries removal, and lasers. The aim of this paper was to discuss various caries removal techniques and possibilities of their use in clinical practice. Based on the literature review it can be concluded that none of the new caries removal methods can completely replace conventional rotary instruments.
Full Text Available The objectives of this study were to evaluate osseointegration of dental implant in the jaw bone in the young and elderly population and comparing the results to assess indicators and risk factors as age for the success or failure of dental implants. A retrospective study of 107 implants (Impladent, LASAK, Czech Republic was prepared. The patients at implants surgery were divided in three groups. The patients were followed-up for a 7-year period. We evaluated osseointegration from long term point of view as a change of marginal bone levels close to dental implant. Marginal bone levels were recorded and analysed with regard to different patient- and implant-related factors. An influence of chronological age on change of marginal bone levels during 6-year retrospective study vas evaluated. The study examined 47 patient charts and 107 implants from the Second Faculty of Medicine, Charles University and University Hospital Motol. We proved that young healthy patients with long bridges or Branemarks have the same progression of marginal bone levels changes. The chronological age hasn’t therefore direct influence on the osseointegration from long term point of view. But we found that the length of dental suprastrucure-prosthetic construction negatively influences marginal bone changes, though these results weren’t statistically significant. More extensive dental implant suprastrucure undergoes smaller osseointegration. On the other hand the length of dental suprastrucure (prosthetic construction negatively influences dental osseointegration in both groups of patient.
Dental implant has tried at the early stage in 19th century recovering an oral function and esthetics. Technological revolutions in biochemical and new materials have developed on the remarkable change in the dental implants, nowadays we call the three generation therapy for dental implantology. There are many kinds of methods and techniques in dental implants, however a lot of troublesome complication on the process of surgical phase, construction of prothodontics and prognosis of maintenance care. In the proceedings of this symposium, I would like to propose you how to manage the maintenance care for various kind of dental implants through the methodology and case presentations. Tendenay and future for dental implants The current outlook of dental implant has increasing supply and demand not only dentists but also patients. According to Japanese Welfare Ministry's report in 1987, average missing teeth over sixty years old generations are approximately 42% in accordance with NIDR (U.S.A.) research. They are missed on ten over teeth in full 28th teeth dentitions owing to dental caries and periodontal diseases. Generally speaking, latent implant patients are occupied on the same possibility of needs for dental implants both Japan and U.S.A. Management of maintenance care The patients hardly recognized the importance of plaque control for the maintenance care in the intraoral condition after implantation. Dentists and dental staffs must be instruct patients for importance of plaque removal and control, because they already had forgotten the habit of teeth cleaning, especially in the edenturous conditions. 1) Concept of establishment in oral hygiene. Motivation and instruction for patients include very important factors in dental implants as well as in periodontal diseases. Patients who could not achieve on good oral hygiene levels obtained no good results in the long term observations. To establish good oral hygiene are how to control supra plaque surrounding tissues

The purpose of this study was to evaluated the diagnostic performance of the senior dental students for the proximal dental caries in intraoral radiographs and to compare it with the dental hospital residents, the reference group. It was also investigated the diagnostic performance according to the carious lesion depth. Thirty-five intraoral periapical and bitewing radiographs with 213 proximal surface included in this study were selected from the dental patients at Chonnam National University Hospital. The observers were 181 senior dental students from 5 dental schools and 40 dentists who were second year resident from 5 dental hospitals. They were asked to evaluate the presence ro the absence of the proximal dental caries. The results were as follows : 1. The mean of the hitting rate for the overall observers was 184.51 surfaces and the diagnostic accuracy was 86.62%. 2. The diagnostic performance of the sound proximal tooth surfaces was very high, i.e., 91.5% true negative rate and 8.5% false positive rate. 3. The diagnostic performance of the dentist group was higher than the student group (P 0.001).

The study aims to determine the degree of anxiety pertaining to dental procedures and various oral hygiene practices among college teenagers. Corah's Modified Dental Anxiety Scale was administered on a randomly chosen sample of 100 Indian college students (50 males and 50 females) of Delhi University, belonging to the age group of 17-20 years. Descriptive statistical computations revealed 12.14 years as the mean age of first dental visit, with moderately high levels of anxiety (60.75%) for various dental procedures among the Indian teenagers and 5% lying in the "phobic or extremely anxious" category. With merely 4.16% people going for regular consultations, general check-ups evoked 78.3% anxiety and having an injection or a tooth removed was perceived as the most threatening. The sample subgroup not using mouthwash and mouthspray, smokers, and alcohol drinkers with improper oral hygiene practices experienced much higher anxiety towards routine dental procedures. The majority of the Indian youngsters had an evasive attitude of delaying dental treatment. The core problems lay in deficient health care knowledge, lack of patient-sensitive pedagogy to train dental professionals, inaccessibility of services, and a dismissive attitude towards medical help. The feelings of fear and anxiety prevalent among the Indian youth offer significant insights into causes and preventive measures for future research and practice. Methods of education and motivation could be developed to dissipate the anxiety amongst Indian teenagers that prevent routine dental visits and maintenance of adequate oral hygiene.
