The prevention of tooth decay and the treatment of lesions and cavities are ongoing challenges in dentistry. In recent years, biomimetic approaches have been used to develop nanomaterials for inclusion in a variety of oral health-care products. Examples include liquids and pastes that contain nano-apatites for biofilm management at the tooth surface, and products that contain nanomaterials for the remineralization of early submicrometre-sized enamel lesions. However, the treatment of larger visible cavities with nanomaterials is still at the research stage. Here, we review progress in the development of nanomaterials for different applications in preventive dentistry and research, including clinical trials.

Preventive measures in dental radiography for radiation protection of both the patients and occupational personnel (and at the same time giving maximum diagnostic yield) are described. The amount of X-radiation to the patients can be reduced by filtration and collimation of X-ray beam, eliminating tube-head leakage and using lead impregnated aprons while radiographing children and female patients in their reproductive age. Exposure of the operator can be minimized by the proper choice of his position and distance from the radiation source and placing a barrier between him and the source.

Objectives: Determine the domain of preventive dentistry in nursing personnel assigned to a primary care unit. Methods: Prospective descriptive study, questionnaire validation, and prevalence study. In the first stage, the questionnaire for the practice of preventive dentistry (CPEP, for the term in Spanish) was validated; consistency and reliability were measured by Cronbach's alpha, Pearson's correlation, factor analysis with intra-class correlation coefficient (ICC). In the second stage, the domain in preventive dental nurses was explored. Results: The overall internal consistency of CPEP is α= 0.66, ICC= 0.64, CI95%: 0.29-0.87 (p >0.01). Twenty-one subjects in the study, average age 43, 81.0% female, average seniority of 12.5 were included. A total of 71.5% showed weak domain, 28.5% regular domain, and there was no questionnaire with good domain result. The older the subjects were, the smaller the domain; female nurses showed greater mastery of preventive dentistry (29%, CI95%: 0.1-15.1) than male nurses. Public health nurses showed greater mastery with respect to other categories (50%, CI95%: 0.56-2.8). Conclusions: The CDEP has enough consistency to explore the domain of preventive dentistry in health-care staff. The domain of preventive dentistry in primary care nursing is poor, required to strengthen to provide education in preventive dentistry to the insured population. PMID:25386037

Previous studies have shown that the state of oral health in the area of Podrinje Canton is really poor. Taking into account that in the last five years are implemented two projects in the municipality it is necessary to examine the impact of preventive measures in dentistry on the oral health. a) To evaluate the impact of continuing education and local fluoridation on the state of oral health; b) To analyze the economic importance of preventive measures. For the purpose of the research on activities of continuing education on the importance of oral health and local fluoridation of teeth and to determine the economic aspects of the application of preventive measures is tested and reviewed 900 students from fourth to ninth grade. The children were divided into three groups of 300 students in each group: a) In the first group of children is carried out continuous education about proper tooth brushing and the importance of oral hygiene and local fluoridation twice a year during the last three years, b) In the second group children carried out local fluoridation twice a year during the last three years while in the third group, there were no continuous prevention measures; c) Used is a single questionnaire for all respondents. Data obtained in this study were analyzed by descriptive and inferential statistical methods. The importance of continuing education and local fluoridation is clearly reflected in the different values DMF-index, which was the subject of research. In the first group, in which is carried out continuous education and local fluoridation value of DMF index was 2.7, in the second group with local fluorination this value was 3.56, while in the third group, in which is not implemented preventive measures, the value DMF- index was 5.93. From an economic point the preventive measures are the cheapest, most effective and the best solution in order to maintain oral health.

A previous study has shown that dental practitioners in Benghazi believed that the less prevention-oriented education system is one of the barriers to applying preventive dentistry. To assess attitudes and perceived competence of the dental graduates in Benghazi towards prevention and early management of dental caries. A cross-sectional, questionnaire-based survey was conducted among internship students attending the Department of Community and Preventive Dentistry in Faculty of Dentistry, Benghazi, Libya. The participants were asked to provide demographic information, to respond to statements about their attitudes towards preventive dentistry, and to answer questions regarding their perceived competence in applying preventive dentistry procedures. Data from 108 Libyan dental graduates were analysed for this study, of which 64% of them were females and 42.1% of them passed their final year with grade: acceptable. The most acknowledged aspects of preventive dentistry were being useful and essential to the community (95.4 and 90.8%, respectively). The percentage of participants expressing a proficiency in providing oral hygiene instructions was the highest (95.4%). There were differences between study subgroups in their perceived competence of preventive dental practices by gender and academic performance (p≤0.05). This study highlighted that the currently implemented undergraduate education programme in Benghazi dental school does not provide dentists with the required attitude and skills to fulfil their role in providing preventive-oriented health services.

In today's dental school curricula, an increasing amount of time is dedicated to technological advances, and preventive dentistry topics may not be adequately addressed. Freshman (D1) students participated in a new Introduction to Preventive Dentistry course, which consisted of didactic lectures, active learning breakout sessions and case-based studies. The goal of this study was to determine if D1 dental students completing the course had a better knowledge and comfort level with basic preventive dentistry concepts and caries risk assessment than the upcoming graduating senior dental students. Following the completion of the course, D1 students were administered a survey that assessed their comfort level describing preventive dentistry topics to patients. This was immediately followed by an unannounced examination over the same topics. Senior (D4) students, who had not taken a formal course, reported statistically significant higher comfort levels than D1 students. However, the D4s scored significantly lower in all of the examination areas than the D1 students. Higher scores in D1s may have been due to recent exposure to the course material. However, the basic nature of the content-specific questions should be easily answered by novice practitioners educating their patients on oral disease prevention. As the current data shows lower content-specific scores of basic preventive dentistry knowledge amongst graduating D4 students, this may indicate a need for more guidance and education of students during the patient care. This study showed that implementation of a formalised course for D1 students can successfully ameliorate deficiencies in knowledge of preventive dentistry topics. © 2014 John Wiley & Sons A/S.

Oral diseases are progressive, cumulative, and become more intricate to treat with advancement. While dental caries is an infectious transmissible disease with children being at the highest risk, primary prevention can reduce this risk. Primary prevention in dentistry is usually considered to be community fluoridated water supplies, professional fluoride treatments, and pit and fissure sealants. While community fluoridated water supplies have been proven to be cost-effective, the cost-effectiveness of pit and fissure sealants has primarily been studied in school-based programs of children from low socio-economic backgrounds. Dental sealant programs are just one way to help increase primary prevention in the oral health disparities of children. The purpose of this paper is to review the literature regarding the cost-effectiveness of pit and fissure sealants as a preventive strategy in preventive dentistry.

All sectors of society should be involved in reducing substance misuse, including businesses. However, the business sector is typically involved only to the extent that their products compel them to be (e.g., alcohol producers promoting responsible alcohol consumption). This article examines why business participation has been limited and how embedding prevention within a framework of health promotion could increase participation. It reviews both Hungarian and international cases, concluding that although corporate social responsibility (CSR) offers a framework to approach substance misuse reduction, a different perception of the role of the business sector is necessary to make it viable.

The application of different preventive measures has resulted in a decline of clinically detectable carious lesions in children and adolescents. Not only have caries symptoms changed significantly, but the number of extracted teeth in adults has decreased. Due to these epidemiological facts, modern conservative dentistry is based on a careful risk analysis and caries diagnosis, which also takes into consideration biological and psychosocial components of caries etiology. Conservative dentistry will fail if the dentists are only interested in repairing defects. Simultaneous with the positive outcome of prevention, some unanswered problems have arisen, for which there are no adequate solutions. In young children, caries prevalence is still high and the restorative care of these primary teeth should be improved. For adolescents, early detection of carious lesions should be improved and polarization of caries prevalence should be eliminated. In older adults, evidence-based therapy options for treatment of erosions, abrasions, and root caries are lacking. For seniors needing general care, preventive and restorative concepts should be established.

Non-Restorative Cavity Treatment (NRCT) is not as popular in paediatric dentistry as it should be. Substantial quantitative and qualitative evidence concerning the treatment has now been published that testifies to the success of the treatment. Some healthcare providers apply the method successfully, while others have no trust in this non-invasive cavity treatment and continue to favour the restoration of carious lesions. Reasons given for this are, among others, that NRCT is too bothersome, the patient's (or the patient's parents') compliance is low and the reimbursement is inadequate. Children, however, benefit from oral healthcare providers who take the position that a child has a right to an etiological treatment that addresses the source of the caries process and that NRCT offers a uniquely viable treatment option for this purpose. This approach fits within the parameters established by professional ethics and the law. Apart from oral healthcare providers, all agencies involved in the profession and beyond have the moral and social obligation to do justice to the implied question of the child regarding this shift in oral healthcare.

The purpose of this article is to compare published evidence supporting procedures to prevent dental caries and periodontal disease, in low-risk patients, with the actual preventive recommendations of practicing dentists. Methods included (1) a survey questionnaire of general dentists practicing in western New York State concerning the preventive procedures they would recommend and at what intervals for low-risk children, young adults, and older adults; and (2) review of the published, English-language literature for evidence supporting preventive dental interventions. The majority of dentists surveyed recommended semiannual visits for visual examination and probing to detect caries (73% to 79%), and scaling and polishing to prevent periodontal disease (83% to 86%) for low-risk patients of all ages. Bite-wing radiographs were recommended for all age groups at annual or semiannual intervals. In-office fluoride applications were recommended for low-risk children at intervals of 6 to 12 months by 73% of dentists but were recommended for low-risk older persons by only 22% of dentists. Application of sealants to prevent pit and fissure caries was recommended for low-risk children by 22% of dentists. Literature review found no studies comparing different frequencies of dental examinations and bite-wing radiographs to determine the optimal screening interval in low-risk patients. Two studies of the effect of scaling and polishing on the prevention of periodontal disease found no benefit from more frequent than annual treatments. Although fluoride is clearly a major reason for the decline in the prevalence of dental caries, there are no studies of the incremental benefit of in-office fluoride treatments for low-risk patients exposed to fluoridated water and using fluoridated toothpaste. Comparative studies using outcome end points are needed to determine the optimal frequency of dental examinations and bite-wing radiographs for the early detection of caries, and of scaling

First, the development of dental health care for children in the Netherlands is discussed. Caries prevalence among children has declined sharply. The present situation, however, makes clear that the majority of carious cavities in the temporary dentition remain untreated. This has led to the conclusion that the level of restorative care has to increase. On the basis of new insights in cariology gained in recent decades, the authors of this article argue for abandoning the old paradigm of restorative treatment in favour of prevention in the treatment of caries.

To identify economic evaluation models and parameters that could be replicated or adapted to construct a generic model to assess cost-effectiveness of and prioritise a wide range of community-based oral disease prevention programmes in an Australian context. The literature search was conducted using MEDLINE, ERIC, PsycINFO, CINHAL (EBSCOhost), EMBASE (Ovid), CRD, DARE, NHSEED, HTA, all databases in the Cochrane library, Scopus and ScienceDirect databases from their inception to November 2012. Thirty-three articles met the criteria for inclusion in this review (7 were Australian studies, 26 articles were international). Existing models focused primarily on dental caries. Periodontal disease, another common oral health problem, was lacking. Among caries prevention studies, there was an absence of clear evidence showing continuous benefits from primary through to permanent dentition and the long-term effects of oral health promotion. No generic model was identified from previous studies that could be immediately adopted or adapted for our purposes of simulating and prioritising a diverse range of oral health interventions for Australian children and adolescents. Nevertheless, data sources specified in the existing Australian-based models will be useful for developing a generic model for such purposes.
The full benefit of prevention science will not be realized until we learn how to influence organizational practices. The marketing of tobacco, alcohol, and food and corporate advocacy for economic policies that maintain family poverty are examples of practices we must influence. This paper analyzes the evolution of such practices in terms of their selection by economic consequences. A strategy for addressing these critical risk factors should include: (a) systematic research on the impact of corporate practices on each of the most common and costly psychological and behavior problems; (b) empirical analyses of the consequences that select harmful corporate practices; (c) assessment of the impact of policies that could affect problematic corporate practices; and (d) research on advocacy organizations to understand the factors that influence their growth and to help them develop effective strategies for influencing corporate externalities.

Considering that parents are the main perpetrators of this type of aggression, parenting programs are needed to raise children without violence. This study aimed at performing a systematic review of parenting programs evaluations to reduce corporal punishment. Intervention procedures, as well as design, results and limitations were identified for each study. The PRISMA protocol (Preferred Reporting Items for Systematic reviews and Meta-Analyses was used for reporting the results. A literature survey was conducted in Brazilian databases, as well as English ones from 1994-2014. One Brazilian study and eight international studies were selected as relevant, and only four used randomized controlled trials (RCT. All studies reported satisfactory results in decreasing aggression by parents against their children. Further research in the area with solid methodology is recommended.

On 23 June 2016, eligible UK voters will be asked to decide whether to vote in the EU referendum. The EU impacts on our daily lives in more ways than many people realise. Dentistry is affected by EU legislation. Examples include the movement of dental professionals, the import of dental equipment and materials, as well as health and safety legislation. Many more EU dentists and DCPs come to the UK to work than vice versa. These numbers have increased markedly since 2004. The result of the vote may affect how dentistry operates in the UK in future years. In addition, a vote to stay would not necessarily prevent change. There are attempts underway to increase the ease by which professionals can work in other member states, especially on a temporary basis. This too is likely affect dentistry at some point. Workforce planners and policy makers should factor in the impact of the EU in future dental policy.

Disciplines comprise of behavior guidance, care of the medically and developmentally compromised and disabled patient, supervision of orofacial growth and development, caries prevention, sedation, pharmacological management, and hospital dentistry including other traditional fields of dentistry. The skills apply to the ever-changing stages of dental, physical, and psychosocial development for treating conditions and diseases distinctive to growing individuals. Hence with the changing scope of practice it is imperative that the clinician stays updated with the current evidence based trends in practice, collaborates with other disciplines and Imparts quality oral health care tailored to the specific needs of every child.
Full Text Available In recent years, the engagement of corporations in child trafficking has become a matter of growing importance. Many corporations have adopted global subcontracting systems and complex structures that boost their productivity and profits, but might also create more opportunities for trafficking and exploitation of both adults and children. Taking this context into account, the ways in which corporations can commit child trafficking will be explored and exemplified to highlight their diversity. This paper also offers a brief overview of the response given by international and European anti-trafficking instruments concerning corporate criminal liability for child trafficking. Moreover, the mechanisms adopted by some companies to prevent trafficking and promote transparency within their supply chains will also be addressed. Overall, this paper aims to illustrate the pivotal role of corporations from two perspectives: as potential perpetrators of this serious crime, and as necessary actors to prevent it. El compromiso empresarial sobre el tráfico infantil es un asunto de creciente importancia. Muchas corporaciones han adoptado sistemas globales de subcontrataciones y complejas estructuras que incrementan su productividad y sus beneficios, pero que también podrían crear más oportunidades para la trata y la explotación de adultos y niños. Partiendo de este contexto, se exploran y ejemplifican las diversas formas en que las corporaciones pueden cometer tráfico infantil. El artículo repasa brevemente la respuesta de los instrumentos internacionales y europeos en lo tocante a la responsabilidad penal de las corporaciones por la trata infantil, y aborda los mecanismos adoptados por algunas empresas para prevenir la trata y promover la transparencia en sus cadenas de suministro. En suma, se pretende ilustrar el rol crucial de las corporaciones desde dos puntos de vista: como potenciales perpetradores de este grave crimen y como actores necesarios
Full Text Available Dentistry is a profession dedicated to promote health and wellness of the people. Green dentistry is a relatively new emerging concept in dentistry. Most dental offices are privately-owned small businesses and have no financial advantage to invest in many environmental-friendly practices. For this reason, more research is needed to find cost-effective environmental alternatives in dentistry. The aim of this article is to expand awareness and practice of eco-friendly dentistry.

Successful treatment and prevention of periodontal disease in pet animals requires a multidimensional approach to identify and eliminate exacerbating factors, provide scheduled professional examinations and care, and plan and implement a dental homecare program. Over the years, many therapeutic and preventive interventions have been developed or advocated for periodontal disease, but evidence of efficacy or effectiveness is highly variable. Accordingly, the main objective of this systematic review is to identify and critically appraise the evidence supporting various aspects of homecare for prevention of canine and feline periodontal disease.

Full Text Available Major oil spills normally occur from oil pipelines and oil tankers that are under operational control of companies, namely, oil companies and tanker owners. There are two generic responses for changing the behavior of companies with regard to oil spill prevention: mandatory government regulation or voluntary initiatives often pursued under the banner of Corporate Social Responsibility (CSR. Here we investigate to what extent voluntary CSR initiatives can be effective in oil spill prevention. A global perspective on voluntary mechanisms is taken by looking at the progress of 20 oil and gas firms from around the world toward oil spill prevention, using the companies' 2010 sustainability reports for self-reported oil spill information. The analysis includes ten oil companies from OECD countries (including Exxon and Shell, among others and 10 oil companies from non-OECD countries (including Brazil's Petrobras and Indian Oil, among others. The study finds that oil spill prevention has generally improved over recent decades. Government regulation played a significant part in these improvements whereas it is less clear to what extent CSR played a significant part in these improvements. Some of CSR's key limitations are highlighted. It is not suggested that CSR should be abandoned; however, new hybrid forms of regulation that combine voluntary and mandatory elements are advocated.

The technology in dentistry has been developed significantly lately, increasing the technological level of new materials, methods and equipment have been developed. Undoubtedly the CO2 laser has contributed to this evolution particular to the treatment of the infected dentin. CO2 laser can sterilize and promote increase 6 to 8 times of dentin resistance, through the transformation the hydroxyapatite in calcium-phosphato-hydroxyapatite. We can reassure our patients about the use of pulsed CO2 laser due to better preservation of dental structure and its benefits permitting advanced esthetic treatments. The CEREC system, registers a tri-dimensional image of the preparation through a scan system, and sends it to the computer and the operator will edit the restorations so the equipment will finish porcelain restoration. The authors used a new laser 650 nm for caries detection and the other low lever laser (670 nm and 730 nm) considered an auxiliary method to prevent and treat the hypersensitivity in dentin.

A long-term study in adults at a public dental clinic in Sweden was initiated to evaluate the relative effectiveness of prophylactic treatments on the progression of dental caries and periodontal discase. With treatments scheduled every 3rd, 6th, 12th or 18th month, this report presents results on caries for the 3-month, 6-month and 18-month groups, and evaluates the impact of various caries-related risk factors. Caries increment over approximately 5 years was determined by adding clinical and radiographic findings of manifest primary and secondary caries during the study. Overall caries activity among all 105 participating individuals was low to moderate. No significant differences for caries on any of the various tooth surfaces or for total caries were observed among the three groups. Multiple regression analysis with 5-year caries increment as dependent variable showed that the following factors had a statistically significant association with caries increment: percentage filled surfaces at baseline examination, dietary score, plaque score, and number of mutans streptococci and lactobacilli in saliva. Non-significant factors included number of preventive treatments provided during the 5-year interval. The results of this long-term trial suggest that preventive treatments as often as every 3 6 months may not be justified in the case of patients with low to moderate caries activity.

More than 200 different diseases may be transmitted from exposure to blood in the dental setting. The aim of this study is to identify possible faults in the crosscontamination chain control in a dental school clinic searching for traces of blood in the clinical contact surfaces (CCS) through forensic luminol blood test. Traces of invisible blood where randomly searched in CCS of one dental school clinic. Forty eight surfaces areas in the CCS were tested and the presence of invisible and remnant blood was identified in 28 (58.3%) items. We suggest that the luminol method is suitable for identifying contamination with invisible blood traces and this method may be a useful tool to prevent cross-contamination in the dental care setting.

Dental caries remains a challenge in the improvement of oral health. It is the most common and widespread biofilm-dependent oral disease, resulting in the destruction of tooth structure by the acidic attack from cariogenic bacteria. The tooth is a heavily mineralised tissue, and both enamel and dentine can undergo demineralisation due to trauma or dietary conditions. The adult population worldwide affected by dental caries is enormous and despite significant advances in caries prevention and tooth restoration, treatments continue to pose a substantial burden to healthcare. Biomaterials play a vital role in the restoration of the diseased or damaged tooth structure and, despite providing reasonable outcomes, there are some concerns with clinical performance. Amalgam, the silver grey biomaterial that has been widely used as a restorative material in dentistry, is currently in throes of being phased out, especially with the Minimata convention and treaty being signed by a number of countries (January 2013; http://mercuryconvention.org/Convention/) that aims to control the anthropogenic release of mercury in the environment, which naturally impacts the use of amalgam, where mercury is a component. Thus, the development of alternative restoratives and restoration methods that are inexpensive, can be used under different climatic conditions, withstand storage and allow easy handling, the main prerequisites of dental biomaterials, is important. The potential for using biologically engineered tissue and consequent research to replace damaged tissues has also seen a quantum leap in the last decade. Ongoing research in regenerative treatments in dentistry includes alveolar ridge augmentation, bone tissue engineering and periodontal ligament replacement, and a future aim is bioengineering of the whole tooth. Research towards developing bioengineered teeth is well underway and identification of adult stem cell sources to make this a viable treatment is advancing; however, this

Advertising in dentistry has steadily increased since the 1970s to become a leading choice of many dentists to promote their practices. The manner in which advertising progresses within the profession affects all dentists and how patients perceive dentistry as a profession. This paper presents ethical concepts that should be followed when dentists are pursuing practice promotion through advertising. It also raises questions that, hopefully, will increase attention and discussion on dental advertising. The paper concludes that ethical advertising is easily achieved by promoting patient education while not placing the dentist's self-interests ahead of the patient's. With this approach, dentistry may continue to be one of the most trusted professions.
Full Text Available Technological and scientific innovations have increased exponentially over the past years in the dentistry profession. In this article, these developments are evaluated both in terms of clinical practice and their place in the educational program. The effect of the biologic and digital revolutions on dental education and daily clinical practice are also reviewed. Biomimetics, personalized dental medicine regenerative dentistry, nanotechnology, high-end simulations providing virtual reality, genomic information, and stem cell studies will gain more importance in the coming years, moving dentistry to a different dimension.

Narrative medicine strives toward a humanized form of medicine in which empathy and the ability to listen are developed with the same emphasis as scientific rigor. We hypothesize that the adoption of narrative medicine in dentistry would be an excellent method to cultivate the philosophy behind the emerging clinical concept of patient-centered dentistry. Reading literary works, reflective writing, and creative writing would sensitize practitioners to the daily lives of people, human uniqueness, and alterity. Narrative dentistry could lead to more empathic and self-aware practices, and improve dental professionals' observational abilities by making them more perceptive and more attentive to image, metaphor, and meaning. The introduction of narrative dentistry would enrich the clinical clerkship of dentists by bringing the often-missing humanities to the dental professional, academic, and scientific environment.

Despite all the dental information acquired over centuries and the importance of proteome research, the cross-link between these two areas only emerged around mid-nineties. Proteomic tools can help dentistry in the identification of risk factors, early diagnosis, prevention, and systematic control that will promote the evolution of treatment in all dentistry specialties. This review mainly focuses on the evolution of dentistry in different specialties based on proteomic research and how these tools can improve knowledge in dentistry. The subjects covered are an overview of proteomics in dentistry, specific information on different fields in dentistry (dental structure, restorative dentistry, endodontics, periodontics, oral pathology, oral surgery, and orthodontics) and future directions. There are many new proteomic technologies that have never been used in dentistry studies and some dentistry areas that have never been explored by proteomic tools. It is expected that a greater integration of these areas will help to understand what is still unknown in oral health and disease. Copyright © 2013 Wiley Periodicals, Inc.
Impact of the "Guidelines for infection prevention in dentistry" (2006) by the Commission of Hospital Hygiene and Infection Prevention at the Robert Koch-Institute (KRINKO) on hygiene management in dental practices - analysis of a survey from 2009.
Hübner, Nils-Olaf; Handrup, Stephan; Meyer, Georg; Kramer, Axel
To assess trends in hygiene management in dental practices in comparison to an earlier survey in 2002/2003 and to point out key aspects for future efforts. The infection prevention management of all dental practices in Greifswald (n=35) was determined by a questionnaire in a personal interview in 2008/2009. 26% of the dentists did not use sufficient personal protective equipment during the general examination of the patient. In conservative and prosthetic dentistry, 15% still did not use adequate measures and 9% did not even in surgical interventions. Vaccination coverage was clearly too low, as only 35% of dentists were vaccinated against influenza and coverage with other vaccinations was also quite low. 11% of the dentists did not perform a documented anamnesis and in 29% of the dental practices no appointment system for risk patients existed.There were significant deficiencies in the reprocessing of medical devices and in the equipment needed for reprocessing. The opportunity to participate in further training in this field was rejected by 23% of the dentists.In 10 dental practices, the colony count in the dental unit water-conducting system was five times higher than the limit. A contamination with P. aeruginosa was discovered in 4 practices. All units were renovated. Overall, both the hygiene management and hygiene equipment in the practices have improved considerably compared to the previous survey in 2002/2003. This demonstrates the positive effect of the KRINKO guidelines from 2006. However, the survey again showed relevant deficiences in the hygiene management of dental practices, which agrees with a Germany-wide online survey from 2009. While the study revealed persistent deficiencies in hygiene management, especially in reprocessing, it confirms that the KRINKO guidelines for dental practices from 2006 led to significant improvements in hygiene management. Doubts about the impact of the guidelines are not backed by evidence.

Knowledge of the physical characteristics of different laser lights and optical and thermal properties of oral tissues is very important to understand the interaction of dental lasers with biological tissues. Choosing the correct dental laser is crucial to match specific wavelengths with target chromophores of different tissues; this affinity makes laser irradiation selective and therefore minimally invasive. Various types of lasers are used in dentistry, offering a viable alternative to low and high-speed handpieces and surgical blades, and also minimising fear and discomfort of the patient. Lasers can provide innovative and minimally invasive therapies in different branches of dentistry including preventive and restorative dentistry, traumatic injury treatments and surgical procedures. Laser has also biostimulating and anti-inflammatory effects, as well as analgesic effect.
Full Text Available History of dentistry in the Central Serbian District of Jagodina has been influenced by traditional medicine for centuries. Development of dentistry in the region of Jagodina was slow, the level of oral and general hygiene was low and the sanitary prevention was absent. Trained physicians started to practice medicine and dentistry in the first half of the nineteenth century and they were educated in abroad universities. However, common people used to address to these physicians only when the traditional medicine were unable to help. Until the end of the World War II, common, mostly rural people, with the urgent dental treatment need were usually referred to the barbers, healers or empirics in the nearby villages rather than the dentists. Medications used for the urgent dental treatment were balsams and solutions made of herbs. After the World War II, the dental technicians who finished special courses started to practice dentistry. In 1947 the Regional Dental Office in Jagodina was opened and in 1955 the first Doctor of Dental Medicine who graduated from the School of Dental Medicine of University of Belgrade was employed. Nowadays, the Department of Dentistry represents is an important and independent part of the Health Care Centre in Jagodina.

Establishes as a duty for the dentist detect problems related to the athlete’s stomatognathic system. This essay is based on the provided data from the literature related to SD, including definition, practice areas and research fields. To discuss the data, six areas were categorized: shares in sports dentistry; oral health of athlete; sports-related dental implications; dental-facial trauma; face shields; and mouthguards. The analyzed data show that the SD is still an underexplored field of action by dentists, but it is expanding, despite not being recognized specialty by the Federal Council of Dentistry, but the Brazilian Academy of Sports Dentistry has been created with a mission to show the real importance of Dentistry in sport. The dentist should be part of the group of professionals associated with the athlete to perform periodic checks in order to ensure oral health which may contribute to athletes´performance. When impact occurs, however, it would be possible reduce the severity of the impact related to injuries, by using helmets, masks, goggles, face shields and mouthguard. Additionally, it is imperative that dentists, sports coaching, athletes, and professional who work with athletes be aware of the benefits of incorporating SD as an important academic and professional subject.

A review of literature regarding informed consent in dentistry reveals a paucity of information and minimal scholarship devoted to this subject. But this begs the question about informed consent somehow being different for dentistry than for medicine or other healthcare delivery. My account draws distinctions where appropriate but is rooted in the premise that informed consent is an ethical construct applicable to vulnerable people as patients independent of what type of treatment or body part being considered. This paper highlights the crucial importance of the process of informed consent and refusal in dentistry, underscoring its important place in oral healthcare. This paper will not address the unique circumstances involving consent in those without capacity or focus on informed consent in the research setting; our focus will be on those patients with full decisionmaking capacity in the clinical setting. I will emphasize the importance of disclosure of treatment options and highlight the benefits of shared-decision-making in the informed consent process.

Most dental practitioners act as their own radiographer and radiologist, unlike their medical colleagues. Virtually all dental surgeons have a dental X-ray machine for intraoral radiography available to them and 40% of dental practices have equipment for dental panoramic tomography. Because of the low energy of X-ray equipment used in dentistry, radiation incidents tend to be less serious than those associated with other aspects of patient care. Details of 47 known incidents are given. The advent of the 1985 and 1988 Ionising Radiation Regulations has made dental surgeons more aware of the hazards of radiation. These regulations, and general health and safety legislation, have led to a few dental surgeons facing legal action. Because of the publicity associated with these court cases, it is expected that there will be a decrease in radiation incidents arising from the practice of dentistry. (author)

Full Text Available Personalized medicine is a branch of medicine that proposes customization of healthcare in which decisions and treatment are tailored according to individual patient needs. The field of personalized medicine relies on genetic information, proteomic information and clinical patient characteristics to individualize treatment. With advances in genetics, proteomics, pharmacogenetics and knowledgeable patient population, the opportunity exists to deliver never before levels of personalized care. Although general dentists may consider personalized medicine a concept for the future, the reality is that its direct application to everyday dentistry is closer than one might think. Use of personalized medicine in dentistry, especially in periodontology is progressing rapidly, and dentist should consider this approach while treating patients. Google and PubMed search was done to select articles for present review. Total 17 articles were used to compile information.

of this review is to inform practitioners with the most updated information on tissue engineering and its potential applications in dentistry. The authors used "PUBMED" to find relevant literature written in English and published from the beginning of tissue engineering until today. A combination of keywords was used as the search terms e.g., "tissue engineering", "approaches", "strategies" "dentistry", "dental stem cells", "dentino-pulp complex", "guided tissue regeneration", "whole tooth", "TMJ", "condyle", "salivary glands", and "oral mucosa". Abstracts and full text articles were used to identify causes of craniofacial tissue loss, different approaches for craniofacial reconstructions, how the tissue engineering emerges, different strategies of tissue engineering, biomaterials employed for this purpose, the major attempts to engineer different dental structures, finally challenges and future of tissue engineering in dentistry. Only those articles that dealt with the tissue engineering in dentistry were selected. There have been a recent surge in guided tissue engineering methods to manage periodontal diseases beyond the traditional approaches. However, the predictable reconstruction of the innate organisation and function of whole teeth as well as their periodontal structures remains challenging. Despite some limited progress and minor successes, there remain distinct and important challenges in the development of reproducible and clinically safe approaches for oral tissue repair and regeneration. Clearly, there is a convincing body of evidence which confirms the need for this type of treatment, and public health data worldwide indicates a more than adequate patient resource. The future of these therapies involving more biological approaches and the use of dental tissue stem cells is promising and advancing. Also there may be a significant interest of their application and wider potential to treat disorders beyond the craniofacial region. Considering the

One disadvantage of the rapid advances in modern dentistry is that treatment options have never been more varied or confusing. Compounded by a more educated population greatly assisted by online information in an increasingly litigious society, a major concern in recent times is increased litigation against health practitioners. The manner in which courts handle disputes is ambiguous and what is considered fair or just may not be reflected in the judicial process. Although legal decisions in Australia follow a doctrine of precedent, the law is not static and is often reflected by community sentiment. In medical litigation, this has seen the rejection of the Bolam principle with a preference towards greater patient rights. Recent court decisions may change the practice of dentistry and it is important that the clinician is not caught unaware. The aim of this article is to discuss legal issues that are pertinent to the practice of modern dentistry through an analysis of legal cases that have shaped health law. Through these discussions, the importance of continuing professional development, professional association and informed consent will be realized as a means to limit the legal complications of dental practice. © 2014 Australian Dental Association.

The purpose of this paper was to review various dosimeters used in dentistry and the cumulative results of various studies done with various dosimeters. Several relevant PubMed indexed articles from 1999 to 2013 were electronically searched by typing "dosimeters", "dosimeters in dentistry", "properties of dosimeters", "thermoluminescent and optically stimulated dosimeters", "recent advancements in dosimetry in dentistry." The searches were limited to articles in English to prepare a concise review on dental dosimetry. Titles and abstracts were screened, and articles that fulfilled the criteria of use of dosimeters in dental applications were selected for a full-text reading. Article was divided into four groups: (1) Biological effects of radiation, (2) properties of dosimeters, (3) types of dosimeters and (4) results of various studies using different dosimeters. The present review on dosimetry based on various studies done with dosimeters revealed that, with the advent of radiographic technique the effective dose delivered is low. Therefore, selection of radiological technique plays an important role in dental dose delivery.

The global movements of healthcare professionals and patient populations have increased the complexities of medical interactions at the point of service. This study examines interpreter mediated talk in cross-cultural general dentistry in Hong Kong where assisting para-professionals, in this case bilingual or multilingual Dental Surgery Assistants (DSAs), perform the dual capabilities of clinical assistant and interpreter. An initial language use survey was conducted with Polyclinic DSAs (n = 41) using a logbook approach to provide self-report data on language use in clinics. Frequencies of mean scores using a 10-point visual analogue scale (VAS) indicated that the majority of DSAs spoke mainly Cantonese in clinics and interpreted for postgraduates and professors. Conversation Analysis (CA) examined recipient design across a corpus (n = 23) of video-recorded review consultations between non-Cantonese speaking expatriate dentists and their Cantonese L1 patients. Three patterns of mediated interpreting indicated were: dentist designated expansions; dentist initiated interpretations; and assistant initiated interpretations to both the dentist and patient. The third, rather than being perceived as negative, was found to be framed either in response to patient difficulties or within the specific task routines of general dentistry. The findings illustrate trends in dentistry towards personalized care and patient empowerment as a reaction to product delivery approaches to patient management. Implications are indicated for both treatment adherence and the education of dental professionals. Copyright © 2015 Elsevier Ltd. All rights reserved.

Antibiotics are commonly used in dentistry for prophylactic as well as for therapeutic purposes. Most often antibiotics are used in unwarranted situations, which may give rise to resistant bacterial strains. Dentists want to make their patients well and to prevent unpleasant complications. These desires, coupled with the belief that many oral problems are infectious, stimulate the prescribing of antibiotics. Good knowledge about the indications of antibiotics is the need of the hour in prescr...
Full Text Available Abstract This paper identifies and characterizes the environmental maturity level of local and multinational high-technology corporations located in Brazil. This characterization is achieved by discussing the adoption of environmental management practices and considering aspects of the productive process stage. An eight-case study was conducted through data triangulation using interviews with employees in diverse organizational areas, direct observations and secondary data. The results indicate the differences in environmental positioning among the studied corporations with a predominance of preventive practices, i.e., an emphasis on eco-efficiency and compliance with legislation. It was also noted that environmental concerns in the corporations are related to internationalization and, in some cases, to the pressure exerted by corporations that represent the brand of the products produced in Brazil. Moreover, the adoption of environmental practices based on the productive process stage supported the environmental maturity classifications of the studied companies.

Demand for economic evaluations in health care is growing with expectations that they will help to develop regional and national policies on health and social programmes. We present here the scope, quality and content of systematic reviews and meta-analyses relating to the economics of dentistry published over the last 15 years. To review the quality and outcome of systematic reviews and meta-analyses relating to the economics of dental treatments, preventions and services. A systematic search was conducted in 14 electronic databases for systematic reviews and meta-analyses published between January 1997 and July 2011 on the economics of oral disorders and oral health care. Review papers were extracted by two independent investigators to identify the characteristics, results and quality of the reviews and to highlight gaps in knowledge about the economics of dentistry. From 3150 unique references, we found 73 systematic reviews or meta-analyses of dental economics as primary or secondary outcomes. The focus of 12 of them was on the cost or cost-effectiveness of dental prevention, 54 on treatment, five on prevention and treatment and two on delivery of dental services. However, only 12 of the systematic reviews drew conclusions from economic data, and four of them constructed an economic model from synthesized data. Overall, the quality was good in the 12 systematic reviews but poor in the original studies. There is very little helpful data published on the economics of dentistry. © 2013 John Wiley & Sons A/S.

Full Text Available Magnets have generated great interest within dentistry. They have been used for various applications in orthodontics and prosthodontics. Earlier use of magnets was limited due to the unavailability of small size magnets, but after the introduction of rare earth magnets and their availability in smaller sizes, their use has increased considerably. They can be placed within prostheses without being obtrusive in the mouth. Their main use in orthodontics has been for tooth movement and in prosthodontics has been in maxillofacial prosthesis and in overdentures as retentive aids. This article reviews the types of magnets available and their application in maxillofacial prosthesis and overdentures, followed by other advantages and disadvantages.

Recent increases in caries prevalence in young children throughout the world highlight the need for a simple but effective infant oral care programme. This programme needs to include a medical disease prevention management model with an early establishment of a dental home and a treatment approach based on individual patient risk. This article presents an updated approach with practical forms and tools based on the principles of caries management by risk assessment, CAMBRA. This method will aid the general practitioner to develop and maintain a comprehensive protocol adequate for infant and young children oral care visits. Perinatal oral health is vitally important in preventing early childhood caries (ECC) in young children. Providing dental treatment to expectant mothers and their young children in a 'dual parallel track' is an effective innovative strategy and an efficient practice builder. It promotes prevention rather than intervention, and this may be the best way to achieve long-lasting oral health for young patients. General dental practice can adopt easy protocols that will promote early preventive visits and anticipatory guidance/counselling rather than waiting for the need for restorative treatment.
After over two decades of discussions, promises and indecisions, the year 2016 marked the birth of the School of Specialisation in Paediatric Dentistry, which is now a reality. The importance of dental post-graduate specialisation schools has been debated since the Degree Course in Dentistry was established. Previously, in Italy only two dental branches - Oral Surgery and Orthodontics - had obtained the recognition that a School of Specialisation entails. Today, with specific training and the newly- established hyper-specialisation in Paediatric Dentistry, the future of the profession is brighter than ever. This will allow dental professionals to provide the best cure to our young patients but it especially marks and recognises the importance of prevention in general. Having established a Specialty School in Paediatric Dentistry is also important to keep the pace with the other European countries where this postgraduate course has been already offered for many years. In my opinion, training professionals with a solid specialisation based both on cultural insights and hands-on clinical activities translates into the possibility of making true prevention. The ultimate goal of paediatric dentists, as well as paediatricians, is certainly to treat young patients but also and above all to accompany them toward an adulthood possibly free of pathologies. With an eye to a future where Paediatric Dentistry will be at the core of dental and orthodontic prevention, I wish great success to all the many specialisation schools established within the Italian Universities.

Criminal law in dentistry, as shaped and moulded by the prevailing views of society, defines what is or is not socially acceptable. It applies in both personal and professional contexts with the intended consequence of protecting the public from unacceptable conduct and potential imbalances of power. At its centre, a patient's consent plays a pivotal role in transforming unlawful conduct into lawful conduct. This literature review considers the current law and the trend of utilizing criminal law in addition to non-criminal law alternatives of reprimanding clinicians for failure to achieve consent in the course of dental practice. Dentists must appreciate this change and the prosecuting authority's increasing willingness to resort to criminal law. © 2017 Australian Dental Association.

Summary The 21st century dental practice is quite dynamic. New treatment protocols and new materials are being developed at a rapid pace. Ozone dental therapy falls into the category of new treatment protocols in dentistry, yet ozone is not new at all. Ozone therapy is already a major treatment modality in Europe, South America and a number of other countries. What is provided here will not be an exhaustive scientific treatise so much as a brief general introduction into what dentists are now doing with ozone therapies and the numerous oral/systemic links that make this subject so important for physicians so that, ultimately, they may serve their patients more effectively and productively.

Piezosurgery, or the use of piezoelectric devices, is being applied increasingly in oral and maxillofacial surgery. The main advantages of this technique are precise and selective cuttings, the avoidance of thermal damage, and the preservation of soft-tissue structures. Through the application of piezoelectric surgery, implant-site preparation, bone grafting, sinus-floor elevation, edentulous ridge splitting or the lateralization of the inferior alveolar nerve are very technically feasible. This clinical overview gives a short summary of the current literature and outlines the advantages and disadvantages of piezoelectric bone surgery in implant dentistry. Overall, piezoelectric surgery is superior to other methods that utilize mechanical instruments. Handling of delicate or compromised hard- and soft-tissue conditions can be performed with less risk for the patient. With respect to current and future innovative surgical concepts, piezoelectric surgery offers a wide range of new possibilities to perform customized and minimally invasive osteotomies. PMID:26635486

One of the major causes of anxiety in the dental clinic is the dental handpiece. Because dentists wish to provide a method which can replace the drill there has often been a premature use of the laser in dentistry. Various lasers have been introduced into the clinic before research has shown the laser used is of clinical benefit. Any new treatment method must not compromise the health of the patient being treated. Thus a method of evaluating the clinical abilities of dentists and their understanding the limitations of the laser used must be developed. Dentist must be trained in the basic interaction of the laser on oral tissues. The training has to concentrate on the variation of the laser wavelength absorption in the different tissues of the oral cavity. Because of the differences in the optical properties of these tissues great care must be exercised by practitioners using lasers on patients.

The purpose of this paper is to review the phenomenon of nanotechnology as it might apply to dentistry as a new field called nanodentistry. Treatment possibilities might include the application of nanotechnology to local anesthesia, dentition renaturalization, the permanent cure for hypersensitivity, complete orthodontic realignment in a single visit, covalently bonded diamondized enamel, and continuous oral health maintenance using mechanical dentifrobots. Dental nanorobots could be constructed to destroy caries-causing bacteria or to repair tooth blemishes where decay has set in, by using a computer to direct these tiny workers in their tasks. Dental nanorobots might be programed to use specific motility mechanisms to crawl or swim through human tissue with navigational precision, to acquire energy, to sense and manipulate their surroundings, to achieve safe cytopenetration, and to use any of a multitude of techniques to monitor, interrupt, or alter nerve-impulse traffic in individual nerve cells in real time.

Full Text Available The successful practice of dentistry involves a good combination of technical skills and soft skills. Soft skills or communication skills are not taught extensively in dental schools and it can be challenging to learn and at times in treating dental patients. Guiding the child′s behavior in the dental operatory is one of the preliminary steps to be taken by the pediatric dentist and one who can successfully modify the behavior can definitely pave the way for a life time comprehensive oral care. This article is an attempt to revisit a simple behavior guidance technique, reframing and explain the possible psychological perspectives behind it for better use in the clinical practice.

Today, dentists and hygienists have inadequate tools to identify contributing factors to dental disease, diagnosis of disease or to document outcomes in a standardized and machine readable format. Increasing demand to find the most effective care methodologies make the development of further terminologies for dentistry more urgent. Preventive care is the focus of early efforts to define best practices. We reviewed one possibility with a history of public health documentation that might assist in these early efforts at identifying best practices. This paper examines, through a survey of dentists, the Omaha System Problem Classification Scheme. The survey requested that dentists rate the usefulness of knowing about specific signs and symptoms for each of the 42 problems within the Problem list of the Omaha System. Using a weighted scoring system, 22 of the 42 problems received over 50% of the possible maximum score and 30 of the 42 problems received at least 25% of the possible points. These findings suggests that further evaluation of The Omaha System, may be useful to dentistry. At a minimum, the survey provides additional information about non-physiological problems, signs, and symptoms that may be appropriate for documentation purposes within an electronic health record (EHR) used in dentistry.

The purpose of this study was to evaluate web-based Knowledge, Attitude and Practice (KAP) intervention on office ergonomics - a unique method for prevention of musculoskeletal discomfort (MSD) - in corporate offices that influences behavior modification. With the increasing use of computers, laptops and hand-held communication devices globally among office employees, creating awareness on office ergonomics has become a top priority. Emphasis needs to be given on maintaining ideal work postures, ergonomic arrangement of workstations, optimizing chair functions, as well as performing desk stretches to reduce MSD arising from the use of these equipment, thereby promoting safe work practices at offices and home, as in the current scenario many employees work from home with flexible work hours. Hence, this justifies the importance of our study. To promote safe working by exploring cost-effective communication methods to achieve behavior change at distant sites when an on-site visit may not be feasible. An invitation was sent by the Medical and Occupational Health Team of a multinational corporation to all employees at their offices in Sri Lanka, Singapore, and Malaysia to take up an online Nordic questionnaire, a screening tool for musculoskeletal symptoms, shared in local languages on two occasions - baseline evaluation ( n = 240) and a follow-up evaluation after 3 months ( n = 203). After completing the baseline questionnaire, employees were immediately trained on correct postures and office ergonomics with animation graphics. The same questionnaire was sent again after a 12-week gap only to those employees who responded to the baseline questionnaire on initial assessment. Data collected were analyzed using the Statistical Package for the Social Sciences (SPSS) version 20.0 software and variables were compared using odds ratio as well as Chi-square test. Of the 203 employees who responded, 47.35% had some musculoskeletal symptoms. Among them 58.7% had lower back pain

Originally, dentists were particularly technical and curative practitioners. Nowadays, patient care is brought into focus, directed at maintaining oral health permanently by prevention and necessary curative treatments as a contribution to general health and well-being. The changing picture of praccising does not develop as a matter-of-course since many factors have an effect on dental practice. Effecting factors are: content concerning developments, technological advancements, legislation, government policies, organizational aspects, and typical characteristics of dental practitioners. The changing picture of practising dentistry is connected with uncertainty, proves to be hard to control, and some adjustments occur around practising.

Both panegyric and criticism of evidence-based dentistry tend to be clumsy because the concept is poorly defined. This analysis identifies several contributions to the profession that have been made under the EBD banner. Although the concept of clinicians integrating clinical epidemiology, the wisdom of their practices, and patients' values is powerful, its implementation has been distorted by a too heavy emphasis of computerized searches for research findings that meet the standards of academics. Although EBD advocates enjoy sharing anecdotal accounts of mistakes others have made, faulting others is not proof that one's own position is correct. There is no systematic, high-quality evidence that EBD is effective. The metaphor of a three-legged stool (evidence, experience, values, and integration) is used as an organizing principle. "Best evidence" has become a preoccupation among EBD enthusiasts. That overlong but thinly developed leg of the stool is critiqued from the perspectives of the criteria for evidence, the difference between internal and external validity, the relationship between evidence and decision making, the ambiguous meaning of "best," and the role of reasonable doubt. The strongest leg of the stool is clinical experience. Although bias exists in all observations (including searches for evidence), there are simple procedures that can be employed in practice to increase useful and objective evidence there, and there are dangers in delegating policy regarding allowable treatments to external groups. Patient and practitioner values are the shortest leg of the stool. As they are so little recognized, their integration in EBD is problematic and ethical tensions exist where paternalism privileges science over patient's self-determined best interests. Four potential approaches to integration are suggested, recognizing that there is virtually no literature on how the "seat" of the three-legged stool works or should work. It is likely that most dentists

Information that would allow an assessment of the standard of radiological protection in dentistry in the United Kingdom is sparse. The National Radiological Protection Board (previously the Radiological Protection Service) has provided a monitoring and advisory service to dentists for many years but very limited use has been made of this service. In a recent survey, 114 dentists were visited in representative practices in South East England and it was established that only 6.5% of dentists in general practice do not use radiography as an adjunct to their practice (Smith, 1969). In the 88 x-ray sets which were examined, 24% had less than the recommended thickness of aluminium filtration, while 25% had a fixed field size which was larger than necessary for dental radiography; in addition, 27% of the timers were found to have an error of greater than 20% in repetition of the pre-set exposure time. The exposure rate at the cone tip of a dental x-ray unit is generally in the range 1 to 4 R/s. A fault in the timer unit coupled with a failure on the part of the dentist to notice that x-rays are being generated (normally indicated by a red warning light) would rapidly lead to excessive exposure of the patient. Furthermore, a dentist continually holding films in the mouth of his patient would certainly incur a dose well in excess of the permissible hand dose, assuming anaverage work load for the x-ray equipment. Three case histories are given to illustrate the type of hazard that might arise from faulty equipment or bad operating technique.

The call to consume less sugar in order to improve the general health is becoming increasingly loud. The question is in what way consuming less sugar could also contribute to a lower risk of caries. This can be achieved by limiting the frequency of consuming sugary snacks. For oral health reasons, people in the Netherlands are advised not to consume things containing sugar more than four times between meals. Another way to make the diet less cariogenic is to substitute sugar in foods by non-caloric intense sweeteners, caloric sugar alcohols or 'new carbohydrates'. Non-caloric intense sweeteners and caloric sweeteners have been proven to be non-cariogenic. New carbohydrates still have to be individually tested.

Patient safety has always been important and is a source of public concern. Recent high profile scandals and subsequent reports, such as the Francis report into the failings at Mid Staffordshire, have raised those concerns even higher. Mortality and significant morbidity associated with the practice of medicine has led to many strategies to help improve patient safety, however, with its lack of associated mortality and lower associated morbidity, dentistry has been slower at systematically considering how patient safety can be improved. Recently, several organisations, researchers and clinicians have discussed the need for a patient safety culture in dentistry. Strategies are available to help improve patient safety in healthcare and deserve further consideration in dentistry.

Since the early 80's, the use of laser has been introduced in the daily dental practice and the technological development has also provided over time to optimize its use. Various types of lasers with different wavelengths have been developed for use in a handy, easy and ergonomic manner. In daily paediatric dentistry, laser could be a very useful medical device which can completely replace the traditional high hand-piece and bur to realize a "micro-invasive" dentistry and a "clean" surgery, without bleeding and sutures. According to the international literature and in the light of recent researches, this work could give an overview on assisted laser therapy in paediatric dentistry, highlighting advantages and disadvantages of this new technology and pointing out the high compliance of the young patient.

3D printing has been hailed as a disruptive technology which will change manufacturing. Used in aerospace, defence, art and design, 3D printing is becoming a subject of great interest in surgery. The technology has a particular resonance with dentistry, and with advances in 3D imaging and modelling technologies such as cone beam computed tomography and intraoral scanning, and with the relatively long history of the use of CAD CAM technologies in dentistry, it will become of increasing importance. Uses of 3D printing include the production of drill guides for dental implants, the production of physical models for prosthodontics, orthodontics and surgery, the manufacture of dental, craniomaxillofacial and orthopaedic implants, and the fabrication of copings and frameworks for implant and dental restorations. This paper reviews the types of 3D printing technologies available and their various applications in dentistry and in maxillofacial surgery.

In rapidly developing economies, like urban India, where road traffic injury rates are among the world's highest, the corporate workplace offers a non-traditional venue for road safety interventions. In partnership with a major multinational corporation (MNC) with a large Indian workforce, this study aimed to elicit local employee perspectives on road safety to inform a global corporate health platform. The safety attitudes and behaviours of 75 employees were collected through self-report survey and focus groups in the MNC offices in Bangalore and Pune. Analysis of these data uncovered incongruity between employee knowledge of safety strategies and their enacted safety behaviours and identified local preference for interventions and policy-level actions. The methods modelled by this study offer a straightforward approach for eliciting employee perspective for local road safety interventions that fit within a global strategy to improve employee health. Study findings suggest that MNCs can employ a range of strategies to improve the road traffic safety of their employees in settings like urban India including: implementing corporate traffic safety policy, making local infrastructure changes to improve road and traffic conditions, advocating for road safety with government partners and providing employees with education and access to safety equipment and safe transportation options.

Management of the health of oral tissues is a prime requirement in dentistry. The prevention of tooth decay and the treatment of lesions and cavities are ongoing challenges. The limitations in dental materials, medications, instruments, procedures put off the accomplishment of this goal. Rationalization of science and technology has made possible to work out these limitations. Nanotechnology which is the outcome of this rationalization has become one of the most favored technologies in medical and dental application. The substantial contribution of nano dental materials is the identification of oral health related problems by better diagnosis and management of dental disorders by bionanomaterials. Application of nanodentistry holds promise for comprehensive dental care by utilizing nanomaterials and ultimately by nanorobots. This review discusses the rationale of nanodentistry, nanocarriers researched in treatment of different dental diseases, the latest innovations in nanomaterials in various disciplines of dentistry; patent literature and related marketed products. Advances in nanotechnology have placed plenty of hopes in terms of improving the oral health care of dental patients.

The aim of this introduction to this special laser issue is to describe some basic laser physics and to delineate the potential of laser-assisted dentistry in children. A brief review of the available laser literature was performed within the scope of paediatric dentistry. Attention was paid to soft tissue surgery, caries prevention and diagnosis, cavity preparation, comfort of the patient, effect on bacteria, long term pulpal vitality, endodontics in primary teeth, dental traumatology and low level laser therapy. Although there is a lack of sufficient evidence taking into account the highest standards for evidence-based dentistry, it is clear that laser application in a number of different aetiologies for soft tissue surgery in children has proven to be successful. Lasers provide a refined diagnosis of caries combined with the appropriate preventive adhesive dentistry after cavity preparation. This will further lead to a new wave of micro-dentistry based on 'filling without drilling'. It has become clear from a review of the literature that specific laser applications in paediatric dentistry have gained increasing importance. It can be concluded that children should be considered as amongst the first patients for receiving laser-assisted dentistry.

Full Text Available Introduction. Dental professionals may be at increased risk of developing occupational allergic diseases specially to methacrylates that can permeate protective disposable gloves. Case report. We presented a case of occupational allergic contact dermatitis in a 28-year-old dental technician. The patient had complained of itching and cracking of fingers for 6 months. The dermatitis improved over weekends. Skin erythema and scaling were present with primarily involvement of the fingertips. Patch testing with dental series gave positive vesicular reaction to methyl methacrylate. Follow-up after 6 months of allergen avoidance showed a complete regression of dermatitis. Conclusion. Methacrylates serve as bases for acrylic resins which are used in prosthetics. Methyl methacrylate as a small molecular acrylate can permeate thin protective disposable gloves. Using adequate personal protective equipment, like nitrile rubber gloves, is the most important preventive measure in this occupation. Health practitioners should recognize possible occupational hazards in dentistry and implement appropriate preventive measures to protect health of workers.

Full Text Available This review aims to trace the contour lines of regenerative dentistry, to offer an introductory overview on this emerging field to both dental students and practitioners. The crystallized depiction of the concept is a translational approach, connecting dental academics to scientific research and clinical utility. Therefore, this review begins by presenting the general features of regenerative medicine, and then gradually introduces the specific aspects of major dental subdomains, highlighting the progress achieved during the last years by scientific research and, in some cases, which has already been translated into clinical results. The distinct characteristics of stem cells and their microenvironment, together with their diversity in the oral cavity, are put into the context of research and clinical use. Examples of regenerative studies regarding endodontic and periodontal compartments, as well as hard (alveolar bone and soft (salivary glands related tissues, are presented to make the reader further acquainted with the topic. Instead of providing a conclusion, we will emphasize the importance for all dental community members, from young students to experienced dentists, of an early awareness rising regarding biomedical research progress in general and regenerative dentistry in particular.

Any intervention involving child victims of intrafamilial abuse must take the alleged underlying motives for the abuse into account. The aim of this study is to further our understanding of intrafamilial physical abuse of children, by comparing its various aspects while considering the alleged underlying motives. A preliminary sample of 1656 cases of alleged physical abuse in the northern region of Portugal was analysed, with two main motives being identified: corporal punishment (CP) (G1 = 927) and exposure to violence between caregivers (EVC) (G2 = 308). Statistically significant differences were found between the two motives (p < 0.05) for the following variables: (1) age of the alleged victims, (2) sex of the alleged abuser, (3) risk factors affecting the alleged abuser, (4) abuser/victim relationship, (5) injury-producing mechanism, (6) time between last abuse and forensic medical examination and (7) location of injuries. Evidence-based knowledge of these differences may help in accurate diagnosis by doctors (particularly forensic physicians) and prevention of this type of violence through support strategies (including tertiary prevention strategies).

Electronic publishing is expanding very rapidly and will soon substitute in part for the traditional role of paper and printing in accessing information and in its library storage. This change is occurring now for medicine and engineering. For dentistry the compact disc (CD-ROM) would have advantages over tape or on-line computer systems; one or two discs a year could hold all current dental journal and textbook literature. The setting of standards is the key to the successful introduction of this technology through production and playback systems. Indexing, retrieval and hardware are considered as well as copyright problems. The profession has the chance to guide the introduction of this publishing system in preference to it being fragmented between multiple publishers and thereby becoming costly. A proposal is offered which includes the nexus of traditional printing with this new publishing form through a forum for considering standards and goals for agreement on principles.

Such devices offer many advantages over conventional hand instruments by reducing both the work and time involved in the clinical descaling process. Although it is a recognised clinical instrument, there has been little attempt to standardise its acoustic power output. A parameter which may characterise adequately the acoustic emission from these instruments is the displacement amplitude of the probe tip. Modification of the ultrasonic descaler generator has led to the further use of the instrument in other dental areas. Diagnostic applications of MHz ultrasound is limited by the structure and arrangement of the dental tissues. Therapeutic ultrasound has been used to treat a variety of dentally related ailments, and ultrasonic cleaning baths are used to clean both dental instruments and materials.

Too many people worldwide suffer from the consequences of untreated dentine carious lesions. This finding reflects the inability of the currently used traditional mode of treatments to manage such lesions. A change is needed. Dental training institutions should depart from the traditional 'drill and fill' treatments and embrace the holistic oral healthcare approach that is minimal intervention dentistry (MID) and includes within it minimally invasive operative skills. Dental caries is, after all, a preventable disease. The atraumatic restorative treatment (ART) concept is an example of MID. ART consists of a preventive (ART sealant) and a restorative (ART restoration) component. ART sealants using high-viscosity glass-ionomer (HVGIC) have a very high dentine carious lesion preventive effect. The survival rate of these sealants is not significantly different from that of sealants produced with resin. The survival rate of ART/HVGIC restorations matches those of amalgam and resin composite in single- and multiple-surface cavities in primary teeth and in single-surface cavities in permanent teeth. The principles of carious tissue removal within a cavity recommended by the International Caries Consensus Collaboration are in line with those of treating a cavity using ART. Owing to its good performance and the low levels of discomfort/pain and dental anxiety associated with it, ART and/or other evidence-based atraumatic care procedures should be the first treatment for a primary dentine carious lesion. Only if the use of ART is not indicated should other more invasive and less-atraumatic care procedures be used in both primary and permanent dentitions.

Full Text Available In today's world, it is very necessary to understand the importance of being eco-friendly in every facet of our lives. The color “green” has healing power and denotes renewal, growth, and hope. “Eco-friendly dentistry” attempts to reduce the detrimental impact of dental practices on the environment and promote environmental awareness and sustainability to patients. This paper attempts to cover all possible aspects of making a dental practice eco-friendly, both in a dental perspective as well as a general perspective. While establishing an eco-friendly dental workplace, the dentist needs to assess his choices in planning the infrastructure and purchasing of equipment and dental materials. Eco-friendly dentistry is a newly evolving practice of dentistry, which encompasses a simultaneous devotion to sustainability, prevention, precaution, and a minimally invasive patient-centric, as well as global-centric treatment. There are two main avenues for implementing eco-friendly dentistry: (1 appropriate policy development and implementation and (2 dentists taking responsibility/ownership in the absence of policies and regulations. Although in some cases, it may take a little extra effort or money; dentists throughout the world are doing their best to reduce the environmental impact of the dental practice. Although the commitment of one small dental office cannot save the planet, certainly, the collective efforts of many small offices as well as large dental hospitals/colleges can ensure that dentists, at least, will not be responsible for destroying it. This article discusses various factors that can be incorporated into dental practice that can help make dentistry eco-friendly.

Full text: For accurate and sure diagnosis in dentistry except anamnestic information (history taking) and clinical examination as an obligatory clinical examination must attend imaging investigation. For diagnosis of diseases of the teeth are used a number of imaging methods. The most widespread of them are segmental roentgenography, ortopamtomography Bitewing, as well as increasingly coming in use dental cone-beam computed tomography (3D CBCT). The aim is to introduce the types of radiographs and their benefits for prompt and proper treatment. Documentary method - a review and analysis of literature and Internet sources are made. Results and comments: Segmented radiography gives us information about the state of the tooth as a whole. Using this method gives an opportunity to visualize the crown, the neck and the root of the tooth. Ortopantomography gives a general view of the state of the maxilla and mandibula, the teeth, part of the maxillary sinuses and temporomandibular joints. Some or extra teeth, are discovered as well as dental disease conditions, bone abnormalities, cysts and others. Bitewing is used when caries is strongly suspected, though not visually, in cases of bone loss and others. The advantage of early and accurate diagnosis is to reduce future complications. Conclusion: good prevention and early detection of dental anomalies and pathologies is performed with the help of X-ray. The selection of the correct method for imaging, the proper use of X-ray machines and placing the required security means reducing the amount of radiation exposure to the patient
The paper, will present the most important non-invasive methods for diagnostic, in different fields of dentistry. Moreover, the laser-based methods will be emphasis. In orthodontics, 3D laser scanners are increasingly being used to establish database for normative population and cross-sectional growth changes but also to asses clinical outcomes in orthognatic surgical and non-surgical treatments. In prevention the main methods for diagnostic of demineralization and caries detection in early stages are represented by laser fluorescence - Quantitative Light Florescence (QLF); DiagnoDent-system-655nm; FOTI-Fiberoptic transillumination; DIFOTI-Digital Imaging Fiberoptic transillumination; and Optical Coherence Tomography (OCT). In odontology, Laser Doppler Flowmetry (LDF) is a noninvasive real time method used for determining the tooth vitality by monitoring the pulp microcirculation in traumatized teeth, fractured teeth, and teeth undergoing different conservative treatments. In periodontology, recently study shows the ability of LDF to evaluate the health of gingival tissue in periodontal tissue diseases but also after different periodontal treatments.

The idea of substituting a drill with a laser light, has led to its introduction in dentistry. Besides being more accepted to patients, in paediatric dentistry the laser has demonstrated safety compared with rotating instruments. A review of the past 20 years of the dental literature concerning laser use in dentistry, including paediatric dentistry was completed. The findings of that review are presented. The various types of lasers and their uses for caries detection, tooth sealing and caries removal are described. Laser caries detection demonstrated a good reproducibility, reliability and predictability to monitor the caries process over time. Erbium lasers have been found to be efficient for caries removal, tooth cleaning and decontamination. The laser erbium technology represents a safe device to effectively and selectively remove carious tissues from decayed teeth. For children, all the recognized advantages of this technique play a decisive role in the successful day-to-day treatment of dental caries.

Pediatricians differ on the optimal ways to discipline children. The major controversy surrounds the use of corporal punishment. In an effort to resolve this controversy, the American Academy of Pediatrics (AAP) cosponsored a conference entitled "The Short and Long-Term Consequences of Corporal Punishment" in February 1996. This article reviews scientific literature on corporal punishment and summarizes the proceedings from the conference. The authors conclude that, although the research data are inadequate to resolve the controversy, there are areas of consensus. Practitioners should assess the spanking practices of the parent they see and counsel parents to avoid those that are, by AAP consensus, dangerous, ineffective, or abusive.

Objectives: To identify the intranasal (IN) sedatives used to achieve conscious sedation during dental procedures amongst children. Methods: A literature review was conducted by identifying relevant studies through searches on Medline. Search included IN of midazolam, ketamine, sufentanil, dexmedetomidine, clonidine, haloperidol and loranzepam. Studies included were conducted amongst individuals below 18 years, published in English, and were not restricted by year. Exclusion criteria were articles that did not focus on pediatric dentistry. Results: Twenty studies were included. The most commonly used sedatives were midazolam, followed by ketamine and sufentanil. Onset of action for IN midazolam was 5-15 minutes (min), however, IN ketamine was faster (mean 5.74 min), while both IN sufentanil (mean 20 min) and IN dexmedetomidine (mean 25 min) were slow in comparison. Midazolam was effective for modifying behavior in mild to moderately anxious children, however, for more invasive or prolonged procedures, stronger sedatives, such as IN ketamine, IN sufentanil were recommended. In addition, ketamine fared better in overall success rate (89%) when compared with IN midazolam (69%). Intranasal dexmedetomidine was only used as pre-medication amongst children. While its’ onset of action is longer when compared with IN midazolam, it produced deeper sedation at the time of separation from the parent and at the time of anesthesia induction. Conclusion: Intranasal midazolam, ketamine and sufentanil are effective and safe for conscious sedation, while intranasal midazolam, dexmedetomidine and sufentanil have proven to be effective premedications.

Current literature on dental radiology was reviewed in order to seek justification for radiological protection of patients in dental radiography, to explore the different factors affecting patient dose and to derive practical guidance on how to achieve radiological protection of patients in dentistry. Individual doses incurred in dental radiology are in general relatively low, however it is generally accepted that there is no safe level of radiation dose and that no matter how low the doses received are, there is a mathematical probability of an effect. Hence appropriate patient protection measures must be instituted to keep the exposures as low as reasonably achievable (ALARA). The literature review demonstrated that there is considerable scope for significant dose reductions in dental radiology using the techniques of optimisation of protection. The techniques of optimization of protection that can be used to ensure patient dose is as low as reasonably achievable whilst achieving clinically adequate image quality include the following: image receptor selection, image receptor holders, collimation, beam filtration, operating potential and exposure time, patient protective equipment, film exposure and processing, film storage, image viewing, quality assurance, diagnostic reference levels, technique charts and training and education.(au)

Full Text Available Bisphosphonate (BP is a class of drug that prevent the loss of bone mass. It inhibits the resorption of bone by encouraging osteoclast to undergo apoptosis. Considering that oral diseases and dental procedures may lead to teeth instability whereas alveolar bone is the main tooth supporting tissue, forceful indication of this drug is for preventing and minimizing bone resorption following oral surgery and relapse movement in orthodontic treatment. Clinical use of BP in dentistry is limited by risk of osteonecrosis of the jaw (ONJ and of its systemic effects such as an increase of the bone mineral density in another bone area. Topical application with local effect would seem the choice of administration route for usage in dentistry. Until recently, no clinical usage of topical BP has been studied, however some experimental laboratory studies proved that this drug would be beneficial in a wide scope of dental treatments.DOI: 10.14693/jdi.v18i1.154

The purpose of this review was to summarize recent developments regarding photodynamic therapy (PDT) in the field of dentistry. A review of pertinent literature was carried out in PubMED to determine the current position of PDT applications in dentistry. One hundred thirteen relevant articles were retrieved from PubMED by inserting the keywords "photodynamic therapy", "dentistry", "periodontology", "oral surgery", and "endodontics". It is anticipated that this overview will create a specific picture in the practitioner's mind regarding the current status and use of PDT. In spite of different results and suggestions brought about by different researchers, PDT can be considered as a promising and less invasive technique in dentistry. PDT seems to be an effective tool in the treatment of localized and superficial infections. Within the limitations of the present review, it can be concluded that although PDT cannot replace antimicrobial therapy at its current stage, it may be used as an adjunctive tool for facilitating the treatment of oral infections. Oral infections (such as mucosal and endodontic infections, periodontal diseases, caries, and peri-implantitis) are among the specific targets where PDT can be applied. Further long-term clinical studies are necessary in establishing a more specific place of the technique in the field of dentistry.

There is a remarkable phenomenon occurring among health professionals: the development of ongoing, routine collaboration, both in educating the next generation of providers and in delivering care. These new approaches, commonly referred to as interprofessional education and interprofessional collaborative practice, have been introduced into academic health settings and delivery systems throughout the U.S. and the rest of the world; however, the full integration of dentistry in health care teams remains unrealized. In academic settings, dentistry has found ways to collaborate with the other health professions, but most practicing dentists still find themselves on the margins of new models of care delivery. This article provides a perspective on the history and context of the evolution of collaborative approaches to health care and proposes ways in which dentistry can participate more fully in the future.

Dentistry has witnessed tremendous advances in all its branches over the past three decades. With these advances, the need for more precise diagnostic tools,specially imaging methods, have become mandatory.From the simple intra-oral periapical X-rays, advanced imaging techniques like computed tomography, cone beam computed tomography, magnetic resonance imaging and ultrasound have also found place in modern dentistry. Changing from analogue to digital radiography has not only made the process simpler and faster but also made image storage, manipulation(brightness/contrast, image cropping, etc.) and retrieval easier. The three-dimensional imaging has made the complex cranio-facial structures more accessible for examination and early and accurate diagnosis of deep seated lesions. This paper is to review current advances in imaging technology and their uses in different disciplines of dentistry.

Radiation is the transmission of energy through space and matter. Diagnostic radiology uses ionizing radiations which have sufficient energy to ionize atoms or molecules in biological and other systems. X-rays used in diagnostic radiology are a potent mutagenic agent, capable of inducing both gene mutations and chromosomal aberrations. X-rays are extensively used in medical and dental practice for the purpose of diagnosis and treatment. X-rays provide useful information and aid in diagnosis but at the same time they also have the potential to cause harmful effects. In dentistry X-rays are used mainly for diagnosis. Radiation in doses required for dentistry may not present any major risks, however these small doses are not necessarily risk free. Hence, no exposure to X-rays can be considered completely free of risk, so the use of radiation by dentists is accompanied by a responsibility to ensure appropriate protection. Several radiation safety measures have been recommended and advocated to reduce harmful effects. Dental professionals are the only practitioners who perform radiographical examination of their patients themselves. Although the exposure used in dentistry is low every effort should be made to reduce radiation in order to prevent the accumulated dose to the dentist in their lifetime. The dose reduction can be achieved in three main steps. They are decision making, optimising radiologic procedures and patient protection. The potential for undesirable effects must be balanced against the benefits obtained from radiographs. Therefore, the aim of the paper is to review important parameters that must be taken into consideration in the clinical set up to reduce radiation exposure to patients and dental personnel. (author)

Corporal punishment is used for discipline in most homes in the United States. It is also associated with a long list of adverse developmental, behavioral, and health-related consequences. Primary care providers, as trusted sources for parenting information, have an opportunity to engage parents in discussions about discipline as early as infancy. These discussions should focus on building parents' skills in the use of other behavioral techniques, limiting (or eliminating) the use of corporal punishment and identifying additional resources as needed.

This paper explores the entrepreneurial role of dentists in primary care dentistry. It reviews the changing context of dentistry, not least the reforms being introduced by the health and social care bill. It suggests that this new context will reinforce the need to consider the business side of dental practice, in particular, the importance of quality, creativity and innovation, alongside the importance of meeting the needs of patients. An entrepreneurial approach will be required in order to sustain dental practice in an increasingly competitive environment.

Low fusing alloy has been used in dentistry for remount procedures in both fixed and removable prosthodontics, in implant prosthodontics for the fabrication of solid implant casts, in maxillofacial prosthetics as oral radiation shields, and in dental research for its unique properties. Previously, the use of low fusing alloy was thought to offer a high degree of dimensional accuracy. However, multiple in vitro studies have shown that its presumed dimensional accuracy may be questionable. This article reviews the physical properties, metallurgical considerations of low fusing alloy, its applications in dentistry, and a safe, simple method of using low fusing alloy.
Bad outcomes occur in dentistry and sometimes these are the results of dental errors. In both cases, this essay will argue that apologies are very important in maintaining a relationship with the patient that is based on trust and mutual respect. Nevertheless, apologies are often not forthcoming in dentistry for a number of reasons that deserve careful examination. In particular, the dentist's fear that an apology will increase the risk of legal harm will be critiqued. Ethical and psychological reasons for making an apology will be discussed, and strategies to assist clinicians in making an apology will be offered.

To assess a) whether the quality of reporting of randomised controlled trials (RCTs) has improved since the formulation of the Consolidated Standards of Reporting Trials (CONSORT) statement and b) whether there is any difference in reporting of RCTs between the selected public health dentistry journals. A hand search of the journals of public health dentistry was performed and four journals were identified for the study. They were Community Dentistry and Oral Epidemiology (CDOE), Community Dental Health (CDH), Journal of Public Health Dentistry (JPHD) and Oral Health and Preventive Dentistry (OHPD). A total of 114 RCTs published between 1990 and 2009 were selected. CONSORT guidelines were applied to each selected article in order to assess and determine any improvement since the publication of CONSORT guidelines. The chi-square test was employed to determine any statistical significant difference in quality of reporting of RCTs before and after the publication of the CONSORT guidelines. A comparison was also done to determine any statistically significant difference in quality of reporting of RCTs between the selected journals. Title, abstract, discussion and conclusion sections of the selected articles showed adherence to the CONSORT guidelines, whereas the compliance was poor with respect to the methodology section. The quality of reporting of RCTs is generally poor in public health dentistry journals. Overall, the quality of reporting has not substantially improved since the publication of CONSORT guidelines.

Citation analysis is the field of bibliometrics that uses citation data to evaluate the scientific recognition and the influential performance of a research article in the scientific community. The aim of this study was to conduct a bibliometric analysis of the top-cited articles pertaining to implant dentistry, to analyze the main characteristics, and to display the most interesting topics and evolutionary trends. The 100 top-cited articles published in "Dentistry, Oral Surgery, and Medicine" journals were identified using the Science Citation Index Database. The articles were further reviewed, and basic information was collected, including the number of citations, journals, authors, publication year, study design, level of evidence, and field of study. The highly cited articles in implant dentistry were cited between 199 and 2,229 times. The majority of them were published in four major journals: Clinical Oral Implants Research, International Journal of Oral & Maxillofacial Implants, Journal of Clinical Periodontology, and Journal of Periodontology. The publication year ranged from 1981 to 2009, with 45% published in a nine-year period (2001 to 2009). Publications from the United States (29%) were the most heavily cited, followed by those from Sweden (23%) and Switzerland (17%). The University of Göteborg from Sweden produced the highest number of publications (n = 19), followed by the University of Bern in Switzerland (n = 13). There was a predominance of clinical papers (n = 42), followed by reviews (n = 25), basic science research (n = 21), and proceedings papers (n = 12). Peri-implant tissue healing and health (24%), implant success/failures (19.2%), and biomechanical topics (16.8%) were the most common fields of study. Citation analysis in the field of implant dentistry reveals interesting information about the topics and trends negotiated by researchers and elucidates which characteristics are required for a paper to attain a "classic" status.

Periodontal disease is the most common oral disease affecting adults, and although it is largely preventable it remains the major cause of poor oral health worldwide. Accumulation of microbial dental plaque is the primary aetiological factor for both periodontal disease and caries. Effective self-care (tooth brushing and interdental aids) for plaque control and removal of risk factors such as calculus, which can only be removed by periodontal instrumentation (PI), are considered necessary to prevent and treat periodontal disease thereby maintaining periodontal health. Despite evidence of an association between sustained, good oral hygiene and a low incidence of periodontal disease and caries in adults there is a lack of strong and reliable evidence to inform clinicians of the relative effectiveness (if any) of different types of Oral Hygiene Advice (OHA). The evidence to inform clinicians of the effectiveness and optimal frequency of PI is also mixed. There is therefore an urgent need to assess the relative effectiveness of OHA and PI in a robust, sufficiently powered randomised controlled trial (RCT) in primary dental care. This is a 5 year multi-centre, randomised, open trial with blinded outcome evaluation based in dental primary care in Scotland and the North East of England. Practitioners will recruit 1860 adult patients, with periodontal health, gingivitis or moderate periodontitis (Basic Periodontal Examination Score 0-3). Dental practices will be cluster randomised to provide routine OHA or Personalised OHA. To test the effects of PI each individual patient participant will be randomised to one of three groups: no PI, 6 monthly PI (current practice), or 12 monthly PI.Baseline measures and outcome data (during a three year follow-up) will be assessed through clinical examination, patient questionnaires and NHS databases.The primary outcome measures at 3 year follow up are gingival inflammation/bleeding on probing at the gingival margin; oral hygiene self

The Brazilian Dentistry Code of Ethics (DCE), Resolution CFO-71 from May 2006, is an instrument created to guide dentists' behavior in relation to the ethical aspects of professional practice. The purpose of the study is to analyze the above mentioned code comparing the deontological and bioethical focuses. In order to do so, an interpretative analysis of the code and of twelve selected texts was made. Six of the texts were about bioethics and six on deontology, and the analysis was made through the methodological classification of the context units, textual paragraphs and items from the code in the following categories: the referentials of bioethical principlism--autonomy, beneficence, nonmaleficence and justice -, technical aspects and moral virtues related to the profession. Together the four principles represented 22.9%, 39.8% and 54.2% of the content of the DCE, of the deontological texts and of the bioethical texts respectively. In the DCE, 42% of the items referred to virtues, 40.2% were associated to technical aspects and just 22.9% referred to principles. The virtues related to the professionals and the technical aspects together amounted to 70.1% of the code. Instead of focusing on the patient as the subject of the process of oral health care, the DCE focuses on the professional, and it is predominantly turned to legalistic and corporate aspects.

Full Text Available This paper presents evidence on the role of ownership in dealing with corporate expropriation of listed companies in Malaysia. From the perspective of expropriation, a single controlling shareholder is always associated with such behavior due to their power and control at the expense of minority shareholder. However, subsequent individual or coalition of large shareholders can be an important corporate governance tool by providing effective monitoring that would lessen the possibility of expropriation by the controlling shareholder. Relating to that, this study evaluates the role of controlling and large shareholders in dealing with corporate expropriation. It is found that there is a negative relationship between single controlling shareholders and dividend payout ratio indicating that firms with only controlling shareholder will pay a lower dividend due to possible expropriation through profit diversion by controlling shareholder. Using Herfindahl Index as a proxy for ownership contestability, the presence of large shareholders along with controlling shareholder has a positive relationship with dividend payout implying that increased contestability helps to curb the power of controlling shareholder to expropriate fund for their own benefit. In accordance with agency theory, the outcome suggests that large shareholders play a monitoring role in minimizing the Type II agency problem. It is also verifying the argument made based on the Catering Theory of Dividend that the presence of large shareholder brings benefit to all shareholders as they are able to reduce profit diversion by demanding for higher dividend

Oral health is - literally - vital to good general health, not least because the mouth is the sentinel of the body. Dentistry, the Cinderella of health care, faces immense challenges of globalisation. Governments, having spent freely on everything from defence to social security, face mountains of debts which make budget cutbacks essential. Simultaneously, most developed countries have to pay increasing costs of caring for rapidly ageing populations. Dentistry is being pulled two ways: wealthy members of society demand high-end expensive treatment, much of it cosmetic rather than necessary to deal with disease, whereas many millions of poor people in developing countries cannot afford basic dental treatment and may never see a dentist. Too many governments and dentists persist with the expensive and destructive regime of 'drill and fill (and bill)'. International advances in care may not reach the clinician's chair because treatment guidelines and payments are set locally. An international symposium to celebrate Mikako Hayashi becoming Professor of Restorative Dentistry and Endodontology at Osaka University concluded that dentistry should move from an increasingly un-affordable curative model to a cost-effective evidence-based preventive model. The goal is to help people retain healthy natural teeth throughout their lives, as an essential part of enhancing their general health. © 2014 FDI World Dental Federation.

Oral health in childhood is a major problem for global public health. In Brazil, the prevalence of childhood tooth decay varies from 12% to 46%. Dental care treatment in Brazil is almost the exclusive responsibility of primary healthcare (PHC). Therefore, it is essential these professionals are prepared to conduct restorative, endodontic, and exodontic treatments and preventive care in children. Children make up a large proportion of the population in territories requiring advanced dental care provided by PHC in Brazil. To care for these patients, it is necessary to have both manual dexterity and technical knowledge of pediatric dentistry. Accordingly, this study aimed to develop a distance course on pediatric dentistry. A pretest questionnaire consisting of 15 questions was used to assess initial dental knowledge of participants. After completion of a five-module course, participants retook the same initial dental knowledge questionnaire (post-test). Descriptive statistic and paired t test, one-way analysis of variance, and Pearson and Spearman correlation were used, and a significance level of 5% was set. The majority of participants completing the five-module course were women who earned specialty degrees beyond undergraduate studies and currently worked in PHC (>5 years). Participant performance on the dental knowledge questionnaire after completion of the five-module course improved pre- to post-test. These data suggest that completion of a distance course on pediatric dentistry can be an effective tool for improving knowledge of pediatric dentistry in PHC professionals.
Full Text Available Emergence of advanced digital technology has opened up new perspectives for design and production in the field of dentistry. Rapid prototyping (RP is a technique to quickly and automatically construct a three-dimensional (3D model of a part or product using 3D printers or stereolithography machines. RP has various dental applications, such as fabrication of implant surgical guides, zirconia prosthesis and molds for metal castings, maxillofacial prosthesis and frameworks for fixed and removable partial dentures, wax patterns for the dental prosthesis and complete denture. Rapid prototyping presents fascinating opportunities, but the process is difficult as it demands a high level of artistic skill, which means that the dental technicians should be able to work with the models obtained after impression to form a mirror image and achieve good esthetics. This review aims to focus on various RP methods and its application in dentistry.

This paper describes the life and work of Dr. Atanasije Puljo (1878-1944). He was a volunteer in the Balkan wars, an active participant in the First World War; he was the first who noted the importance of team-work of a dentist and a surgeon in the care of jaw and facial injuries. He established primacy in this field, as he came up with this brilliant idea three years before other colleagues. His method of treatment of the upper jaw neglected fractures, called the Balkan method, was recognized worldwide. Dr. Puljo is the pioneer of dental radiology in Serbia, founder of the Odontology Clinic of the Medical Faculty and main supporter of the establishment of the School of Dentistry. Merits of Dr. Atanasije Puljo, medical practitioner with a broad knowledge in different fields, remain within the academic institution that was founded by this pioneer of dentistry in Serbia.
DIN pocketbook 267/4 gives an overview of the normative requirements of the new X-Ray and Radiation Protection Ordinance, which has been in effect since 1 November 2011. This DIN pocketbook is intended for anyone charged with professional responsibility for the use of ionizing radiation in dentistry, operators and users of x-ray devices, radiation protection officers, accredited experts, manufacturers as well as for anyone with an interest in radiation protection or optimal radiological diagnostics. It contains standards relating to the following areas: acceptance and constancy testing; devices for evaluating findings (monitors, film viewing devices), films, printers; archiving, designating, labelling. Adherence to the standards makes it possible to avoid distractive artefacts in x-ray images and optimise the quality of x-ray diagnostics in dentistry.

Complete text of publication follows. Dentistry students were assessed in one of the school of dentistry in Iran. 11% of responders had attended a radiation protection course. This study showed that those who have attended this course had improved knowledge of ALARA principle, assessment of the impact of digital imaging in patient dose reduction and usage of personal dosimeter systems. Course attendance made no considerable difference to knowledge of the patient dose, dose reduction techniques and annual permissible dose limits of general public and radiation workers. The results of this study revealed that the majority of students have not received adequate radiation protection teaching and even if a course has been attended, overall knowledge is still poor and formal teaching at undergraduate level should be corrected in the future.

Managed care plans attempt to control health care expenditures aggressively. These plans directly influence access to medical care and the type, level, and frequency of care rendered. As a result, hospital stays are reduced, focus shifts from inpatient to outpatient care, and patients are responsible for a larger share of health care costs. Dentistry is not immune from the impact of managed care. The attractiveness of the dental market has drawn many managed care organizations, insurers, and entrepreneurs to encourage dentists to participate in a wide variety of managed care programs. However, the delivery of dental care differs markedly in many respects from that of medical care. Therefore, many of the cost saving aspects of managed care that have been so successful in medicine may not result in similar cost savings in dentistry.

Direct reimbursement, or DR, has been a popular topic in organized dentistry for much of the last decade, and the concept is beginning to be more widely known. This article explores the underpinnings of and future for DR. TYPES OF LITERATURE REVIEWED: This article is based on an online review of the dental, medical and business literature. The author explores the advantages of DR for patients, employers and dentists. He also presents purported disadvantages of DR, and refutes them. Organized dentistry's marketing efforts and the importance of third-party administrators also are examined. During the next several years, DR has the potential to become the vehicle of choice for financing much of the dental care provided in the United States. Dentists need to become more aware of what DR is and what it can offer the public. They then will be better able to promote DR, which is a significantly better payment system for dental care than any other available today.

Full Text Available Traditionally, clinical decisions in dentistry have been based on the experience of the dentist. If the given treatment works, it was utilized again, but if the results were disappointing, the procedure was deserted. Evaluating clinical treatment in this fashion is difficult because it is hard to know which factors are important for success and which contribute to failure. This came with the concept of evidence-based approach which facilitates conclusions for clinical practice based on sound research studies.
It took mankind some ten thousand years to get sugarcane from the Pacific to the Mediterranean. Once it reached Europe and the Europeans knew how to handle it, it took them only a hundred years to turn the production of sugar into the biggest industry of the world. Exactly in those hundred years the birth of modern medicine--and dentistry--is placed. This coincidence is too particular to be left unnoticed.

Digital communication offers advantages and challenges to dental practice. As dentistry becomes comfortable with this technology, it is essential that commercial and other values not be accepted on a par with professional ones and that the traditional dentist-patient relationship not be compromised by inserting third parties that introduce nonprofessional standards. The Officers and Regents of the American College of Dentist have prepared this background and position paper as a guide to the ethical use of digital communication in dental practice.

Development of improved designs of implant systems in dentistry have necessitated the study of stress fields in the implant regions of the mandible/maxilla for better understanding of the biomechanics involved. Photoelasticity has been used for various studies related to dental implants in view of whole field visualization of maximum shear stress in the form of isochromatic contours. The potential of digital photoelasticity has not been fully exploited in the field of implant dentistry. In this paper, the fringe field in the vicinity of the connected implants (All-On-Four® concept) is analyzed using recent advances in digital photoelasticity. Initially, a novel 3-D photoelastic model making procedure, to closely mimic all the anatomical features of the human mandible is proposed. By choosing appropriate orientation of the model with respect to the light path, the essential region of interest were sought to be analysed while keeping the model under live loading conditions. Need for a sophisticated software module to carefully identify the model domain has been brought out. For data extraction, five-step method is used and isochromatics are evaluated by twelve fringe photoelasticity. In addition to the isochromatic fringe field, whole field isoclinic data is also obtained for the first time in implant dentistry, which could throw important information in improving the structural stability of the implant systems. Analysis is carried out for the implant in the molar as well as the incisor region. In addition, the interaction effects of loaded molar implant on the incisor area are also studied.

Although human mouth benefits from remarkable mechanical properties, it is very susceptible to traumatic damages, exposure to microbial attacks, and congenital maladies. Since the human dentition plays a crucial role in mastication, phonation and esthetics, finding promising and more efficient strategies to reestablish its functionality in the event of disruption has been important. Dating back to antiquity, conventional dentistry has been offering evacuation, restoration, and replacement of the diseased dental tissue. However, due to the limited ability and short lifespan of traditional restorative solutions, scientists have taken advantage of current advancements in medicine to create better solutions for the oral health field and have coined it "regenerative dentistry." This new field takes advantage of the recent innovations in stem cell research, cellular and molecular biology, tissue engineering, and materials science etc. In this review, the recently known resources and approaches used for regeneration of dental and oral tissues were evaluated using the databases of Scopus and Web of Science. Scientists have used a wide range of biomaterials and scaffolds (artificial and natural), genes (with viral and non-viral vectors), stem cells (isolated from deciduous teeth, dental pulp, periodontal ligament, adipose tissue, salivary glands, and dental follicle) and growth factors (used for stimulating cell differentiation) in order to apply tissue engineering approaches to dentistry. Although they have been successful in preclinical and clinical partial regeneration of dental tissues, whole-tooth engineering still seems to be far-fetched, unless certain shortcomings are addressed.

Full Text Available Medical implants and biological models have three main characteristics: low volume, complex shape, and can be customized. These characteristics suit very well with Rapid Prototyping (RP and Rapid Manufacturing (RM processes. RP/RM processes are fabricated part layer- by-layer until complete shape finished from 3D model. Biocompatible materials, such as Titanium and Titanium alloy, Zirconium, Cobalt Chromium, PEEK, etc, are used for fabrication process. Reverse Engineering (RE technology greatly affects RP/RM processes. RE is used to capture or scan image of the limb, cranium, tooth, and other biological objects. Three common methods to get the image are 3D laser scanning, Computer Tomography (CT, and Magnetic Resonance Imaging (MRI. Main RP/RM techniques used in Dentistry are Stereotype Lithography Apparatus (SLA, Fused Deposition Modeling (FDM, Selective Laser Sintering (SLS, and ink jet printing. This article reviews the changing scenario of technology in dentistry with special emphasis on Rapid Prototyping and its various applications in Dentistry.

The objective of this study was to systematically assess the informational value, intention, source, and bias of videos related to dentistry available on the video-sharing Internet platform YouTube. YouTube (www.youtube.com) was searched for videos related to dentistry, using the system-generated sorts "by relevance" and "most viewed" and two categories (All and Education). Each of the first thirty results was rated by two assessors filling out a questionnaire for each (total: 120). The data were subjected to statistical analysis using Cohen's kappa, Pearson's correlation coefficient tau, Mann-Whitney U-tests, and a nonparametric three-way ANOVA, including an analysis of the interaction between the sorting and category effect, with an α-level of 5 percent. The scan produced 279,000 results in the category All and 5,050 in the category Education. The analysis revealed a wide variety of information about dentistry available on YouTube. The purpose of these videos includes entertainment, advertising, and education. The videos classified under Education have a higher degree of usefulness and informational value for laypersons, dental students, and dental professionals than those found in a broader search category. YouTube and similar social media websites offer new educational possibilities that are currently both underdeveloped and underestimated in terms of their potential value. Dentists and dental educators should also recognize the importance of these websites in shaping public opinion about their profession.
Full Text Available Contemporary dentistry is, first of all, characterized by diverse accelerated development, owing to improvements of information and other technologies, as well as the development of dental materials (shape-memory biomaterials, nanomaterials, biomaterials for application in tissue engineering, etc.. Expert doctrinaire attitudes move from the direction of operative interventions, whereby disease and acute symptoms are primarily treated, towards the strengthening of oral health by minimally invasive procedures. A particular place in patients’ total rehabilitation belongs to numerous esthetic procedures which, to a large extent, make up a wants-based service, led by the patients’ needs and affinities. This paper deals with differences between cosmetic and esthetic dentistry. The complexity of esthetic dentistry, which favors therapy with the change of function parameters in care for the patient, is emphasized. On the other hand, more attention is paid to the need to know and respect ethical and marketing principles that follow any activity of dentists, starting from the first contact with the patient, the selection of certified materials, to the implementation of the appropriate treatment plan. Well-directed communication and comprehensive awareness of the patient, the use of the visual analog scale, consideration of realistic resources in therapy, and the acceptance of de Bono model of adopted parallel thinking are determinants which help dentists define a problem adequately, find quality solutions, open alternative solutions, and reduce the potential risks in patients’ therapy.

Plasma-related technologies are essential in modern industries. Recently, plasma has attracted increased attention in the biomedical field. This paper provides a basic knowledge of plasma and a narrative review of plasma applications in dentistry. To review plasma applications in dentistry, an electronic search in PubMed, SCOPUS and Google scholar up to December 2012 was done. This was followed by extensive hand searching using reference lists from relevant articles. There have been attempts to apply plasma technology in various fields of dentistry including surface modifications of dental implants, adhesion, caries treatment, endodontic treatment and tooth bleaching. Although many studies were in early stages, the potential value of plasma for dental applications has been demonstrated. To enlarge the scope of plasma applications and put relevant research to practical use, interdisciplinary research with participation of dental professionals is required.
General dentistry is an important part of the dental medicine and general dentists and general dentistry form the basis of clinical dental medicine. China's general dentistry has a long history, which started as an independent specialist in the 1990s. At present, the Chinese general dental medicine has received more and more attention as an independent profession. General dental medical model has been rapidly developed in the general hospital department of dentistry, private practice and community dentistry institutions, dental specialist hospitals and so on. In this paper, we will review the rise and development of China's general dentistry, and report its theoretical characteristics, institutional framework, academic progress, member development report, and look forward to its development in the future.

The aim of this study was to qualitatively evaluate the experiences of students enrolled in the last year of dentistry school with ergonomic practice. This is a qualitative, observational and cross-sectional study, with a non-probabilistic sample design. The sample comprised students enrolled in the last year of dentistry in Araraquara-UNESP (n = 29). The data were collected by means of open semi-structured and individual interviews, captured by a digital voice recorder. The students were interviewed in their own university at a time that was previously scheduled, and care was taken to provide a private and welcoming environment to carry out the interviews. A script containing questions related to practices in ergonomics was prepared at the university. Data analysis was carried out using the qualitative-quantitative Collective Subject Discourse technique with the aid of Qualiquantisoft ® software program. It was found that more than half of the students (58.6%) believe that adopting an ergonomic posture is important to prevent future problems, pain and occupational diseases, and 62.1% of the students confirm having difficulties in adopting ergonomic postures due to the types of treatment required and the regions of the mouth being treated. The main reasons stated for the fact that their colleagues do not adopt ergonomic postures are lack of attention, practice and forgetfulness (44.8%) and difficulty in visualising the operatory field or the procedure performed (27.6%). It is possible to conclude that the students interviewed know ergonomic principles and their importance in occupational health. However, they found it difficult to put these principles into practice. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Eco-friendly or green dentistry can be a reality by effectively designing dental clinics and using more eco-friendly materials in the clinical practice. To determine the awareness of eco-friendly dentistry among dental faculty and students in preparation for future implementation. Assessment of knowledge regarding eco-friendly dentistry was done using an 18 item self-administered questionnaire among 160 participants. After baseline data collection, the intervention was done by educating participants with a power point presentation. The post-intervention data was then collected for analysis. Statistical analysis was done using Wilcoxon's signed rank test and one-way ANOVA. The educational intervention increased the knowledge about eco-friendly dentistry confirming the importance of continuing education. There was a statistically significant gain in knowledge among the participants after the presentation. The gain was highest for department of Preventive Dental Sciences (PDS) followed by Substitute Dental Sciences (SDS), No specialty, Maxillofacial Dental Sciences (MDS), and Restorative Dental Sciences (RDS) respectively. (F=5.5091, p<0.05). Lack of knowledge of green dentistry amongst the dental fraternity is highly prevailing. The same can be substantiated with effective training in the respective fields if channelized through the curriculum in an educational set-up.

While countries varies significantly in the financing of dental care, they are much more alike in the delivery of dentistry. Dental care is principally provided in dental offices and clinics that are independent business entities whose business leaders are most often the dentists themselves. However society expects from dentists a level of professionalism (i.e. habitually acting ethically, both in terms of competence and conduct) in contrast to the methods and motivations of the marketplace. This is why the single most important challenge of dental professional ethics continues to be giving proper priority to patients' well being and building ethically correct decision-making relationships with patients while, at the same time, trying to maintain a successful business operation. If we look into dentistry's future, the centrality of this aspect of professional ethics is not likely to change, although the ways in which dentists might violate this trust will probably multiple as funding mechanisms become increasingly complex. It is important that dentists reflect with fresh eyes on their ethical commitments. One challenge is the increased availability of oral health information to the public and the fact that so many people are uncritical of the accuracy of information in the media and on the web. A second is the increase in the amount of health care advertising in many societies. A third is the growth of aesthetic dentistry that differs from standard oral health care in important and ethically significant ways. The fourth is insurance that frequently complicates the explanation of a patient's treatment alternatives and often brings a third party into the treatment decision relationship. The ethical challenges of each of these factors will be considered and ultimately tying it to the central theme of dental professionalism.

Full Text Available It was only toward the close of the last century that women emancipated themselves from their former small territory of usefulness in a strictly domestic life, and pushing forward, proved themselves often the business equal to men and sometimes their superior. If was long before this progression, when a women in business or professional ranks was almost a curiosity. When women first entered the profession, they faced many obstacles. Mentors or faculty in the dental organizations majority were male restraining women by all means. In the beginning, men were resentful because they feel women are inferior. It took a long time for women to become a consistent presence in dental schools. In the beginning, dental schools used to admit one or two women each year, later the number increased slowly. Olden day′s women used to relieve not even the tooth ache but also used to relieve others fret also. But histories of dentistry were not acknowledged the talent of women whatsoever. The efforts and achievements of women punch the clock in the future dentistry. The current scenario has totally changed now. Nearly, half of all dental students′ are women and 25% of them are practicing dentists. Only 3% women dentists were there before the 1970s.  Women struggled to obtain a degree, to establish practices, and are respected as professionals. Some women choose this rewarding occupation as career followed by their family members. The population tally of chosen work upbringing has changed over time. This paper reports in a delineative way of the amelioration, staggering presence, and intendment of dentistry practicing by worldwide women.

The human body comprises molecules; hence, the availability of molecular nanotechnology will permit dramatic progress to address medical problems and will use molecular knowledge to maintain and improve human health at the molecular scale. Nanomedicine could develop devices that are able to work inside the human body in order to identify the early presence of a disease, and to identify and quantify toxic molecules and tumor cells, for example. Nanodentistry will make possible the maintenance of comprehensive oral health by employing nanomaterials, including tissue engineering and, ultimately, dental nanorobots. This review is an attempt to highlight the possible applications of nanotechnology and the use of nanomaterials in dentistry. PMID:22131826

Oral fluid-based (salivary) tests have the potential to create practical, point-of-care clinical instruments that are convenient, practical, and comfortable to use in dentistry and medicine. Currently, there are no simple, accurate, and inexpensive sampling, screening, or detection methods to support definitive diagnostic platforms across dental and medical disciplines. Though the benefits from advancing screening and detection technologies seem eminent, analytical, chemical, molecular, genetic, and protein markers are still under development. Clinical applications in patient care must be validated independently to ensure that they are clinically accurate, reliable, precise, and uniformly consistent for screening and detecting specific diseases or conditions. As technology designed to improve patient care through risk assessment, prevention, and disease management is transferred into clinical practice, dentistry may need to reassess its role in general health care. © International & American Associations for Dental Research

Full Text Available Introduction: Lasers are used in various disciplines in dentistry such as restorative dentistry, endodontics, periodontics, pedodontics, and oral and maxillofacial surgery. Despite many advantages of dental lasers, this method might have some adverse effects. The aim of this review article is to debate about the impacts of lasers on orodental tissues. Methods: An electronic search was accomplished using specialized databases such as Google Scholar, PubMed, PubMed Central, Science Direct, and Scopus to find relevant studies by using keywords such as “laser”, “dentistry”, “adverse effect”, and “side effect”. Results: Several adverse effects of laser were identified such as impacts on dental pulp, effects on tooth surface, subcutaneous and submucosal effects, histopathological changes, and infection transmission due to laser smoke. During dental procedures, necrosis of the pulp, periodontal ligament and odontoblasts, cemental lysis, bone resorption, hypo/hyperpigmentation, burns, itching, and scarring might occur. In addition, laser can weaken the dentin by inducing surface cracks. Restorative procedures by laser might increase microleakage and decrease shear bond strength, as well as microhardness of tooth walls. Meanwhile, laser surgery might cause emphysema after abscess incision and drainage, frenectomy, flap elevation, and gingivoplasty. Conclusion: Practitioners should be very cautious in treatment planning and case selection during laser-based therapeutic procedures.

By definition and general agreement, smart materials are materials that have properties which may be altered in a controlled fashion by stimuli, such as stress, temperature, moisture, pH, and electric or magnetic fields. There are numerous types of smart materials, some of which are already common. Examples include piezoelectric materials, which produce a voltage when stress is applied or vice versa, shape memory alloys or shape memory polymers which are thermoresponsive, and pH sensitive polymers which swell or shrink as a response to change in pH. Thus, smart materials respond to stimuli by altering one or more of their properties. Smart behaviour occurs when a material can sense some stimulus from its environment and react to it in a useful, reliable, reproducible, and usually reversible manner. These properties have a beneficial application in various fields including dentistry. Shape memory alloys, zirconia, and smartseal are examples of materials exhibiting a smart behavior in dentistry. There is a strong trend in material science to develop and apply these intelligent materials. These materials would potentially allow new and groundbreaking dental therapies with a significantly enhanced clinical outcome of treatments. PMID:24672407

In 2007, only four years after the completion of the Human Genome Project, the journal Science announced that epigenetics was the 'breakthrough of the year'. Time magazine placed it second in the top 10 discoveries of 2009. While our genetic code (i.e. our DNA) contains all of the information to produce the elements we require to function, our epigenetic code determines when and where genes in the genetic code are expressed. Without the epigenetic code, the genetic code is like an orchestra without a conductor. Although there is now a substantial amount of published research on epigenetics in medicine and biology, epigenetics in dental research is in its infancy. However, epigenetics promises to become increasingly relevant to dentistry because of the role it plays in gene expression during development and subsequently potentially influencing oral disease susceptibility. This paper provides a review of the field of epigenetics aimed specifically at oral health professionals. It defines epigenetics, addresses the underlying concepts and provides details about specific epigenetic molecular mechanisms. Further, we discuss some of the key areas where epigenetics is implicated, and review the literature on epigenetics research in dentistry, including its relevance to clinical disciplines. This review considers some implications of epigenetics for the future of dental practice, including a 'personalized medicine' approach to the management of common oral diseases. © 2014 Australian Dental Association.
Optical coherence tomography (OCT) is a noninvasive and noncontact technique for obtaining cross-sectional images of biologic structure, which was initially introduced to depict the transparent tissue of the eye. It employs the partial coherence properties of a light source to image structures with high resolution (< 20 (m). Recently, this technique has also been applied in turbid media. This tomographic imaging is analogous to conventional ultrasound B mode imaging, except that OCT measures the intensity of backreflected infrared light rather than acoustical waves. First applications, of OCT in dentistry for diagnosing periodontal disease have been reported by Colston et al. presenting in vitro OCT images of the dental and periodontal tissues of porcine premolar teeth. In this work, the feasibility of polarisation sensitive OCT for dental material is suggested. In contrast with conventional OCT, where the magnitude of backscattered light as a function of depth is imaged, backscattered light is used to image the magnitude of the birefringence in the sample as a function of depth. Partial loss of birefringence is known to be an early indication of incipient caries or tissue thermal damage. Applying this technique for caries diagnosis or guidance regarding optimal dosimetry for thermally mediated laser therapeutic procedures, polarisation sensitive OCT would represent a promising new technology for dentistry.

In the last decade, tissue engineering is a field that has been suffering an enormous expansion in the regenerative medicine and dentistry. The use of cells as mesenchymal dental stem cells of easy access for dentist and oral surgeon, immunosuppressive properties, high proliferation and capacity to differentiate into odontoblasts, cementoblasts, osteoblasts and other cells implicated in the teeth, suppose a good perspective of future in the clinical dentistry. However, is necessary advance in the known of growth factors and signalling molecules implicated in tooth development and regeneration of different structures of teeth. Furthermore, these cells need a fabulous scaffold that facility their integration, differentiation, matrix synthesis and promote multiple specific interactions between cells. In this review, we give a brief description of tooth development and anatomy, definition and classification of stem cells, with special attention of mesenchymal stem cells, commonly used in the cellular therapy for their trasdifferentiation ability, non ethical problems and acceptable results in preliminary clinical trials. In terms of tissue engineering, we provide an overview of different types of mesenchymal stem cells that have been isolated from teeth, including dental pulp stem cells (DPSCs), stem cells from human exfoliated deciduous teeth (SHEDs), periodontal ligament stem cells (PDLSCs), dental follicle progenitor stem cells (DFPCs), and stem cells from apical papilla (SCAPs), growth factors implicated in regeneration teeth and types of scaffolds for dental tissue regeneration.
Full Text Available Repair of dental pulp and periodontal lesions remains a major clinical challenge. Classical dental treatments require the use of specialised tissue-adapted materials with still questionable efficacy and durability. Stem cell-based therapeutic approaches could offer an attractive alternative in dentistry since they can promise physiologically improved structural and functional outcomes. These therapies necessitate a sufficient number of specific stem cell populations for implantation. Dental mesenchymal stem cells can be easily isolated and are amenable to in vitro expansion while retaining their stemness. In vivo studies realised in small and large animals have evidenced the potential of dental mesenchymal stem cells to promote pulp and periodontal regeneration, but have also underlined new important challenges. The homogeneity of stem cell populations and their quality control, the delivery method, the quality of the regenerated dental tissues and their integration to the host tissue are some of the key challenges. The use of bioactive scaffolds that can elicit effective tissue repair response, through activation and mobilisation of endogenous stem cell populations, constitutes another emerging therapeutic strategy. Finally, the use of stem cells and induced pluripotent cells for the regeneration of entire teeth represents a novel promising alternative to dental implant treatment after tooth loss. In this mini-review, we present the currently applied techniques in restorative dentistry and the various attempts that are made to bridge gaps in knowledge regarding treatment strategies by translating basic stem cell research into the dental practice.

Neuromuscular dentistry has been a controversial topic in the field of dentistry and still remains debatable. The issue of good occlusion and sound health has been repeatedly discussed. Sometimes we get complains of sensitive teeth and sometimes of tired facial muscles on getting up in the morning. Owing to the intimate relation of masticatory apparatus with the cranium and cervico-scapular muscular system, the disorders in any system, draw attention from concerned clinicians involved in management, to develop an integrated treatment protocol for the suffering patients. There may be patients reporting to the dental clinics after an occlusal restoration or extraction, having pain in or around the temporomandibular joint, headache or neck pain. Although their esthetic demands must not be undermined during the course of treatment plan, whenever dental treatment of any sort is planned, occlusion/bite should be given prime importance. Very few dentist are able to diagnose the occlusal disease and of those who diagnose many people resort to aggressive treatment modalities. This paper aims to report the signs of occlusal disease, and discuss their association with TMDs and posture.
Full Text Available Bioactive glasses are silicate-based and can form a strong chemical bond with the tissues. These biomaterials are highly biocompatible and can form a hydroxyapatite layer when implanted in the body or soaked in the simulated body fluid. Due to several disadvantages, conventional glass processing method including melting of glass components, is replaced by sol-gel method with a large number of benefits such as low processing temperature, higher purity and homogeneity and therefore better control of bioactivity. Bioactive glasses have a wide range of applications, particularly in dentistry. These glasses can be used as particulates or monolithic shapes and porous or dense constructs in different applications such as remineralization or hypersensitivity treatment. Some properties of bioactive glasses such as antibacterial properties can be promoted by adding different elements into the glass. Bioactive glasses can also be used to modify different biocompatible materials that need to be bioactive. This study reviews the significant developments of bioactive glasses in clinical application, especially dentistry. Furthermore, we will discuss the field of bioactive glasses from beginning to the current developments, which includes processing methods, applications, and properties of these glasses.

Tooth wear has been recognised as a major problem in dentistry. Epidemiological studies have reported an increasing prevalence of tooth wear and general dental practitioners see a greater number of patients seeking treatment with worn dentition. Although the dental literature contains numerous publications related to management and rehabilitation of tooth wear of varying aetiologies, our understanding of the aetiology and pathogenesis of tooth wear is still limited. The wear behaviour of dental biomaterials has also been extensively researched to improve our understanding of the underlying mechanisms and for the development of restorative materials with good wear resistance. The complex nature of tooth wear indicates challenges for conducting in vitro and in vivo wear investigations and a clear correlation between in vitro and in vivo data has not been established. The objective was to critically review the peer reviewed English-language literature pertaining to prevalence and aetiology of tooth wear and wear investigations in dentistry identified through a Medline search engine combined with hand-searching of the relevant literature, covering the period between 1960 and 2011. © 2011 Blackwell Publishing Ltd.
Full Text Available The process of economic transition in Serbia has highlighted the problem of socially responsible behavior of corporations and especially the growing phenomenon of corporate crime. The consequences of corporate wrongdoing are almost everywhere and cannot be overseen. The most tremendous ones are those related to human casualties, environmental disasters, long-term negative health effects and great material budget losses on local and state levels. The fact that corporations are profiting from criminal activity which causes enormous damage to society and individuals makes public policy makers face the ultimate choice - either to devise new effective measures for reducing and controlling this phenomenon or to retain the standard model of crime control, in accordance with the principles of classical criminal law. The first choice would require one of the pillars of criminal law - the principle of individual and subjective guilt of physical persons as the exclusive grounds for imposing criminal liability - to be either modified and widened in order to be used as a base for imposing corporate criminal liability or partially changed by new criminal law categories which would introduce different grounds for imposing criminal liability on an organization. The second choice would require the decision-makers to refuse to change old and well-established principles. The criminal reality, however, has made most legislatures in Europe and around the world choose the first option and introduce different forms of corporate criminal liability. Serbian criminal legislation has been headed in the same direction since 2008, when it was changed in order to enable the imposing of liability for criminal acts on corporations. However, although corporate criminal liability is becoming the European legislative standard, one question remains - Is this the only measure of criminal politics which can be used as a means of reducing and preventing corporate crime?

To identify the 100 most cited articles published in dental journals. A search was performed on the Institute for Scientific Information (ISI) Web of Science for the most cited articles in all the journals included in the Journal Citation Report (2010 edition) in the category of "Dentistry, Oral Surgery, and Medicine". Each one of the 77 journals selected was analyzed using the Cited Reference Search tool of the ISI Web of Science database to identify the most cited articles up to June 2012. The following information was gathered from each article: names and number of authors, journal, year of publication, type of study, methodological design, and area of research. The number of citations of the 100 selected articles varied from 326 to 2050. All articles were published in 21 of the 77 journals in the category. The journals with the largest number of the cited articles were the Journal of Clinical Periodontology (20 articles), the Journal of Periodontology (18 articles), and the Journal of Dental Research (16 articles). There was a predominance of clinical research (66 %) over basic research (34 %). The most frequently named author was Socransky SS, with 9 of the top 100 articles, followed by Lindhe J with 7. The decades with most articles published of the 100 selected were 1980-1989 (26 articles) and 1990-1999 (25 articles). The most common type of article was the case series (22 %), followed by the narrative review/expert opinion (19 %). The most common area of study was periodontology (43 % of articles). To our knowledge, this is the first report of the top-cited articles in Dentistry. There is a predominance of clinical studies, particularly case series and narrative reviews/expert opinions, despite their low-evidence level. The focus of the articles has mainly been on periodontology and implantology, and the majority has been published in the highest impact factor dental journals. The number of citations that an article receives does not necessarily reflect the

Diagnostic methods for the use in preventive dentistry are being developed continuously. Few of these find their way into general practice. Although the general trend in medicine is to focus on disease prevention and early diagnostics, in dentistry this is still not the case. Nevertheless, in dental
Corporate financing is the choice between capital generated by the corporation and capital from external investors. However, since the financial crisis shook the markets in 2007–2008, financing opportunities through the classical means of financing have decreased. As a result, corporations have...... to think in alternative ways such as issuing corporate bonds. A market for corporate bonds exists in countries such as Norway, Germany, France, the United Kingdom and the United States, while Denmark is still behind in this trend. Some large Danish corporations have instead used foreign corporate bonds...... markets. However, NASDAQ OMX has introduced the First North Bond Market in December 2012 and new regulatory framework came into place in 2014, which may contribute to a Danish based corporate bond market. The purpose of this article is to present the regulatory changes in Denmark in relation to corporate...

In the early years of the new millennium, the National Institute of Dental and Craniofacial Research of the National Institutes of Health began funding Oral Health Research Education Grants using the R25 mechanism to promote the application of basic and clinical research findings to clinical training and to encourage students to pursue careers in oral health research. This report describes the impact of an R25 grant awarded to the Texas A&M Health Science Center's Baylor College of Dentistry (BCD) on its curriculum and faculty development efforts. At BCD, the R25 grant supports a multipronged initiative that employs clinical research as a vehicle for acquainting both students and faculty with the tools of evidence-based dentistry (EBD). New coursework and experiences in all four years of the curriculum plus a variety of faculty development offerings are being used to achieve this goal. Progress on these fronts is reflected in a nascent EBD culture characterized by increasing participation and buy-in by students and faculty. The production of a new generation of dental graduates equipped with the EBD skill set as well as a growing nucleus of faculty members who can model the importance of evidence-based practice is of paramount importance for the future of dentistry.

Full Text Available Pizosurgery has therapeutic characteristics in osteotomies, such as extremely precise, selective and millimetric cuts and a clear operating field. Piezoelectricity uses ultrasonic frequencies, which cause the points specially designed for osteotomy to vibrate. The points of the instrument oscillate, allowing effective osteotomy with minimal or no injury to the adjacent soft tissues, membranes and nerve tissues. This article presents the various applications of piezoelectricity in oral implant surgery such as: removal of autogenous bone; bone window during elevation of the sinus membrane and removal of fractured implants. The cavitational effect caused by the vibration of the point and the spray of physiological solution, provided a field free of bleeding and easy to visualize. The study showed that the piezoelectric surgery is a new surgical procedurethat presents advantages for bone cutting in many situations in implant dentistry, with great advantages in comparison with conventional instrumentation. Operating time is longer when compared with that of conventional cutters.

Full Text Available Dental biomaterials and natural products represent two of the main growing research fields, revealing plant-derived compounds may play a role not only as nutraceuticals in affecting oral health, but also in improving physico-chemical properties of biomaterials used in dentistry. Therefore, our aim was to collect all available data concerning the utilization of plant polysaccharides, proteins and extracts rich in bioactive phytochemicals in enhancing performance of dental biomaterials. Although compelling evidences are suggestive of a great potential of plant products in promoting material-tissue/cell interface, to date, only few authors have investigated their use in development of innovative dental biomaterials. A small number of studies have reported plant extract-based titanium implant coatings and periodontal regenerative materials. To the best of our knowledge, this review is the first to deal with this topic, highlighting a general lack of research findings in an interesting field which still needs to be investigated.

Documentation and evaluation of dental injuries in forensic medicine are rather problematic. It needs a professional work up why dental injuries are out of focus, and how the diagnosis, pattern and treatment are influenced by novel approaches of dentistry. The aims of the authors were to characterize dental injuries, to compare their own findings to literature data concerning the type and characteristics of injuries, and propose a diagnostic workflow. Expert's reports between 2009 and 2013 at the Department of Forensic Medicine, University of Szeged were reviewed. Review of about 7000 reports revealed only 20 cases with dental injury, which is in contrast with literature data indicating a significantly higher frequency of dental injuries. Although the number of "dental cases" was low, there were several additional cases where the trauma probably affected the teeth but the injury was not documented. In future more attention is needed in forensic evaluation of the mechanism, therapeutic strategy and prognosis of dental injuries.

With the conventional methods of treatment failing to render satisfactory results, gene therapy is not only being used for the cure of inherited diseases but also the acquired ones. The broad spectrum of gene therapy includes its application in the treatment of oral cancer and precancerous conditions and lesions, treatment of salivary gland diseases, bone repair, autoimmune diseases, DNA vaccination, etc. The aim of this article is to throw light on the history, methodology, applications and future of gene therapy as it would change the nature and face of dentistry in the coming years.
Nanotechnology, or nanoscience, refers to the research and development of an applied science at the atomic, molecular, or macromolecular levels (i.e. molecular engineering, manufacturing). The prefix "nano" is defined as a unit of measurement in which the characteristic dimension is one billionth of a unit. Although the nanoscale is small in size, its potential is vast. As nanotechnology expands in other fields, clinicians, scientists, and manufacturers are working to discover the uses and advances in biomedical sciences. Applications of nanotechnology in medical and dental fields have only approached the horizon with opportunities and possibilities for the future that can only be limited by our imagination. This paper provides an early glimpse of nanotechnology applications in medicine and dentistry to illustrate their potentially far-reaching impacts on clinical practice. It also narrates the safety issues concerning nanotechnology applications. © 2011 Blackwell Publishing Asia Pty Ltd.

The speed at which advances are being made in science has catapulted nanotechnology from its theoretical foundations straight into the real world. There are now many examples of commercially available products demonstrating that, in given situations, the technology really does work and that its scope for further application is wide. Healthcare, along with society as a whole, is facing a major revolution in the wake of ongoing technological developments in the field of nanotechnology. Dentistry as an individual healthcare discipline is not exempt, having already been targeted directly with novel 'nano-materials' at the same time as indirectly enjoying the benefits of nano-related advances in the electronics industry through the ongoing computerization of the modern practice. This article examines current practical applications of nanotechnology alongside proposed applications in the future and aims to demonstrate that, as well as a good deal of science fiction, there is some tangible science fact emerging from this novel multi-disciplinary science.

To appraise the reported processes involved in the development of published dental guidelines. Electronic databases were searched to identify guidelines making recommendations for any health professional within dentistry. All included guidelines were appraised using the Appraisal of Guidelines Research and Evaluation (AGREE) instrument. A total of 105 guidelines met the inclusion criteria. The appraised guidelines showed lack of rigour in their development (median score 14.3%; range 0% to 100%). Only 10 (9.5%) were coded as 'strongly recommend' by at least two assessors. If recommendations within clinical guidelines are to be relied upon, the methods used in their development must be explicit and free from bias. When using the AGREE checklist to make decisions on whether or not to implement individual sets of guidelines, the findings of the present assessment reinforce the need for more than two assessors to be included in the appraisal of each set of guidelines.

Titanium and its alloys belong to biomaterials which the application scope in medicine increases. Some properties of the alloys, such as high mechanical strength, low density, low Young's modulus, high corrosion resistance and good biotolerance decide about it. The main areas of the application of titanium and its alloys are: orthopedics and traumatology, cardiosurgery, faciomaxillary surgery and dentistry. The results of investigations concerning the corrosion resistance of the technical titanium and Ti6Al14V alloy and comparatively a cobalt alloy of the Vitallium type in the artificial saliva is presented in the work. Significantly better corrosion resistance of titanium and the Ti6Al14V than the Co-Cr-Mo alloy was found. (author)

Dental fear is a universal phenomenon justifying the increasing relevance of psychology and the behavioural sciences to dental training and clinical practice. Pharmacological sedation has been used more and more over the past two decades, in order to relieve dental anxiety and phobia and let the patient face oral surgery safely. Hypnosis is a still underused but powerful non-pharmacological tool in dentistry. It provides an effective sedation whilst maintaining patient collaboration, but it also may help patients recovering from dental anxiety and phobia as well as those with a severe gag reflex. While pharmacological sedation affords a temporary respite and helps the patient to cope with a single procedure, hypnosis can effectively allow for both an excellent sedation in a physiological way and the treatment of patients' anxiety, or substantially decrease the doses used for sedative and analgesic drugs when these are needed.

Oral disease continues to be a major problem in Australia impacting quality of life, the economy and broader health system. Although the understanding of caries and periodontal disease has improved along with increased government support, oral diseases continue to be the most prevalent among all health conditions. This is despite unprecedented levels of funding in the Chronic Disease Dental Scheme and the Teen Dental Plan. Access to primary care dentistry in the private sector, where the majority of dental services are provided, remains a critical issue. Under the current system of dentistry, it cannot be assumed that the practice of dentistry represents a prioritised approach to combat disease patterns based on scientific evidence in primary health and prevention. Drawing on data in relation to these two programs, the present study highlights issues impacting dental service provision. This includes issues such as access and affordability to dental care, sustainability of policy and its unintended consequences, private practice pressures and the impact of remuneration on treatment. This paper argues that without structural reform there will continue to be barriers in implementing policies capable of improving oral health.

To determine the quality of the evidence for the uses of fluoroscopy in dentistry. A systematic review using Ovid and MEDLINE was conducted to identify papers showing the uses of fluoroscopy in dentistry published between 1953 and September 2009. Human, animal and phantom/skull/mannequin studies on fluoroscopy with regard to its diagnostic value, research performance, and clinical and safety applications in dentistry were included in this analysis. Studies that were not in English, as well as those that employed fluoroscopy in dentistry without the use of image intensification, were excluded. Articles were evaluated, classified and graded by levels of evidence. Fifty-five out of 139 papers fulfilled the inclusion criteria. Amongst them, 19 were related to diagnosis, 15 to research, 12 to clinical and nine to safety applications. Fluoroscopy has contributed to nine different areas of dentistry. Also, it was used on 895 dental patients, 37 animals and 17 phantoms/skulls/mannequins. Two randomised controlled trials, two cohort studies, two case controls, 48 case reports and one expert opinion were found. Fluoroscopy with image intensification has been a useful, but not consistently used tool in dentistry for over 50 years. Several lines of evidence have shown fluoroscopy's diagnostic potential, research use, and clinical and safety applications in dentistry.
Full Text Available The publication Corporate Fraud and Internal Control contains essential guidance for companies to examine and improve their fraud programs: Corporate governance legislation has become increasingly concerned with the ongoing resilience of organizations and, particularly, with their ability to resist corporate fraud from the lowest levels to the upper echelons of executive management. It has become unacceptable for those responsible for corporate governance to claim, "I didn't know". Corporate Fraud and Internal Control focuses on the appropriateness of the design of the system of internal controls in fraud risk mitigation, as well as the mechanisms to ensure effective implementation and monitoring on an ongoing basis.

Full Text Available Objective: To assess the occurrence and characteristics of the reported accidents with perforating-cutting materials involving students, staff and faculty members, between 2000 and 2005 at the Dental Clinic of the School of Dentistry of the University of São Paulo. Methods: A survey of the records of reported occurrences of accidents was made, considering the material that caused the accident, time of day of the occurrence, the discipline in which it occurred, and clinical conduct adopted in the emergency room. When available, the results of the laboratory exams of the accident victim and the source patient were also taken into consideration. Results: The data assessed showed there were 40 accident reports, of which 39 reports involved undergraduate students and 1 staff member. The instrument that caused most accidents was the anesthetic needle and largest number of these accidents occurred in the Surgery discipline. However, 50% of the records did not present complete information, which prevented a more accurate epidemiological assessment. Conclusion: The data obtained led to the conclusion that the rate of accidents is extremely low considering the number of clinical attendances provided in the period and raises the hypothesis that many cases were not reported.

Full Text Available As a response to the need to provide an acceptable thermal comfort and air quality in indoor environments, various ventilation performance indicators were developed over the years. These metrics are mainly geared towards air distribution, heat and pollutant removals. Evidence exists of influencing factors on these indicators as centered on ventilation design and operations. Unlike other indoor environments, health care environment requires better performance of ventilation system to prevent an incidence of nosocomial and other hospital acquired illnesses. This study investigates, using in-situ experiments, the ventilation efficiency in a dentistry surgical room. Thermal and hygric parameters were monitored on the air terminal devices and occupied zone over a period of one week covering both occupied and unoccupied hours. The resulting time-series parameters were used to evaluate the room’s ventilation effectiveness. Also, the obtained parameters were benchmarked against ASHRAE 170 (2013 and MS1525 (2014 requirements for ventilation in health care environment and building energy efficiency respectively. The results show that the mean daily operative conditions failed to satisfy the provisions of both standards. Regarding effectiveness, the findings reveal that the surgical room ventilation is ineffective with ventilation efficiency values ranging between 0 and 0.5 indicating air distribution short-circuiting. These results suggest further investigations, through numerical simulation, on the effect of this short-circuiting on thermal comfort, infection risk assessments and possible design improvements, an endeavour that forms our next line of research inquiries.

There are various risks involved in corporate activities conducted both within and outside the corporation. Among these, health risks are very important and should be managed effectively as an integral part of corporate social responsibility (CSR). A corporation is responsible for health impairments caused by its activities and suffers great moral and economic loss when they occur. It is essential that corporate management takes proper preventive measures against such risks. Occupational physicians possess substantial knowledge of health risks in corporations. In this study, we examine the role of occupational physicians in the management of corporate health risks. Information was obtained from articles in print and on the Internet. Health risks due to corporate activities involve not only the employees of the corporation but also individuals outside the corporation. Each corporation should effectively use available resources to manage health risks. Occupational physicians are one such valuable resource. However, many corporations do not actively involve occupational physicians in health risk management. According to a current Japanese law, health risks for employees in corporations are managed by occupational physicians, but in general, health risks outside corporations are not. The 1984 Bhopal Disaster in India is an example in which physicians of the corporation were only minimally, if at all, involved in assessing and treating impaired health outside the corporation. The role of occupational physicians should be expanded to include management of health risks outside the corporation. This places a greater burden on the physicians and they must make the effort to train in many academic fields in order to better understand the entire context of health risks due to corporate activities. Some occupational physicians may be hesitant to take on such added responsibilities. Some corporations may not recognize the overall health risks due to its activities and do not

Behavior guidance in pediatric dentistry is a composite of influences including expert opinion, historical precedent, scientific studies, and social factors including the law and the media. The early icons of pediatric dentistry injected their personal views on child management, and those often reflected the child-rearing norms of the times. The business of pediatric dentistry with its efficiency and quality orientations also shaped approaches to behavior management. Scientific studies contributed minimally. A major influence on behavior guidelines in recent years has been external scrutiny of techniques prompted by media and other exposure of both private practice and corporate management of children. Changing parenting and reaction of society to authority have also had significant impact on behavior. This paper describes in more detail the evolution of behavior guidance and the subsequent codification of practices into professionally derived guidelines.

Since the 'Francis Report', UK regulation focusing on patient safety has significantly changed. Healthcare workers are increasingly involved in NHS England patient safety initiatives aimed at improving reporting and learning from patient safety incidents (PSIs). Unfortunately, dentistry remains 'isolated' from these main events and continues to have a poor record for reporting and learning from PSIs and other events, thus limiting improvement of patient safety in dentistry. The reasons for this situation are complex.This paper provides a review of the complexities of the existing systems and procedures in relation to patient safety in dentistry. It highlights the conflicting advice which is available and which further complicates an overly burdensome process. Recommendations are made to address these problems with systems and procedures supporting patient safety development in dentistry.

Italian National Health Service (INHS) provides hospital, district and preventive cares in many medical areas but dental cares are a small part of all treatments provided. It is estimated that it only answers a 5% of need. In Italy dental treatments are predominantly provided by private practitioners: it means little access equity to cares. Nowadays, just 1,5% of the INHS expense is aimed at public dentistry because most of dental cares are believed “not urgent”. Why oral diseases are not con...
Local anesthesia forms the major part of pain-control techniques in dentistry. The prevention and elimination of pain during dental treatment has benefited patients, their doctors and dental hygienists, enabling the dental profession to make tremendous therapeutic advances that would otherwise have been impossible. Introduced in the late 1940s, the amide local anesthetics represent the most used drugs in dentistry. Local anesthetics also represent the safest and most effective drugs in all of medicine for the prevention and management of pain. They are also accompanied by various adverse effects which should be well known and be able to be controlled by the clinician. The article reviews the types of agents used as local anesthetics and their effects on the human body.

Purpose The purpose of this paper is to explore selective leadership approaches in the context of dentistry in the UK. Design/methodology/approach This is a conceptual paper utilising published sources from relevant literature about leadership theory and practice and the policy background to dentistry in the UK. Findings This paper suggests that there is merit in identifying and applying an eclectic mix of leadership theory to the case of dentistry. It offers insight into individual aspects of the leadership role for dentists and applies this to the dental context. It also contrasts these individual approaches with shared leadership and suggests this may also be relevant to dentistry. It highlights the fact that leadership will be of growing concern for dentistry in the light of recent policy changes. Research limitations/implications This paper points out that there are developmental implications depending on the particular approach taken. It argues that leadership development will become increasingly important in dentistry in the UK. Originality/value This paper addresses a topic that has so far received limited attention in the literature.

Full Text Available Corporations are at present operating in demanding and highly unsure periods, facing a mixture of increased macroeconomic need, competitive and capital market dangers, and in many cases, the prospect for significant technical and regulative gap. Throughout these demanding and highly unsure times, the corporations must pay particular attention to corporate strategy. In present times, corporate strategy must be perceived and used as a function of various fields, covers, and characters as well as a highly interactive system. For the corporation's strategy to become a competitive advantage is necessary to understand and also to integrate it in a holistic model to ensure sustainable progress of corporation activities under the optimum conditions of profitability. The model proposed in this paper is aimed at integrating the two strategic models, Hoshin Kanri and Integrated Strategy Model, as well as their consolidation with the principles of sound corporate governance set out by the OECD.

Stem cells constitute the source of differentiated cells for the generation of tissues during development, and for regeneration of tissues that are diseased or injured postnatally. In recent years, stem cell research has grown exponentially owing to the recognition that stem cell-based therapies have the potential to improve the life of patients with conditions that span from Alzheimer's disease to cardiac ischemia to bone or tooth loss. Growing evidence demonstrates that stem cells are primarily found in niches and that certain tissues contain more stem cells than others. Among these tissues, the dental pulp is considered a rich source of mesenchymal stem cells that are suitable for tissue engineering applications. It is known that dental pulp stem cells have the potential to differentiate into several cell types, including odontoblasts, neural progenitors, osteoblasts, chondrocytes, and adipocytes. The dental pulp stem cells are highly proliferative. This characteristic facilitates ex vivo expansion and enhances the translational potential of these cells. Notably, the dental pulp is arguably the most accessible source of postnatal stem cells. Collectively, the multipotency, high proliferation rates, and accessibility make the dental pulp an attractive source of mesenchymal stem cells for tissue regeneration. This review discusses fundamental concepts of stem cell biology and tissue engineering within the context of regenerative dentistry.
Full Text Available Zirconia restorations have been used successfully for years in dentistry owing to their biocompatibility and good mechanical properties. Because of their lack of translucency, zirconia cores are generally veneered with porcelain, which makes restorations weaker due to failure of the adhesion between the two materials. In recent years, all-ceramic zirconia restorations have been introduced in the dental sector with the intent to solve this problem. Besides the elimination of chipping, the reduced occlusal space requirement seems to be a clear advantage of monolithic zirconia restorations. However, scientific evidence is needed to recommend this relatively new application for clinical use. This mini-review discusses the current scientific literature on monolithic zirconia restorations. The results of in vitro studies suggested that monolithic zirconia may be the best choice for posterior fixed partial dentures in the presence of high occlusal loads and minimal occlusal restoration space. The results should be supported with much more in vitro and particularly in vivo studies to obtain a final conclusion.

In Italy, consent for health treatment, aside from being an ethical and deontological obligation, constitutes an essential requirement for any medical treatment according to articles 13 and 32 of the National Constitution and also in accordance with the Council of Europe's 'Convention on Human Rights and Biomedicine'. An essential requirement for the validity of consent is that clear, exhaustive and adequate information be provided to the patient himself: the practice of informed consent is a communicative relationship in which the patient can express doubts, perplexities and clarification requests to the dentist. Furthermore, dental treatment has specific peculiarities: the relationship between dentistry and aesthetics, the concomitant presence of pathologies requiring different treatments, the elongated care process and the establishment of a trustworthy relationship and familiarity with the patient represent important aspects in the configuration of the dentist-patient relationship and in the process of acquiring informed consent. The dentist must offer correct information on diagnosis, prognosis, the therapeutic perspective and the likely consequences of therapy, alternative therapy and refusal of therapy, as well as eventual commitments for the period after treatment. Particular consideration must be given to minors and patients of unsound mind: the dentist's approach to these patients needs to be clear and appropriate to the person's age and understanding ability, even if the decisional power for sanitary treatment may be in the hands of a third person.

In dentistry, Radio Visio Graphy was introduced as a first electronic dental x-ray imaging modality in 1989. Thereafter, many types of direct digital radiographic systems have been produced in the last decade. They are based either on charge-coupled device (CCD) or on storage phosphor technology. In addition, new types of digital radiographic system using amorphous selenium, image intensifier etc. are under development. Advantages of digital radiographic system are elimination of chemical processing, reduction in radiation dose, image processing, computer storage, electronic transfer of images and so on. Image processing includes image enhancement, image reconstruction, digital subtraction, etc. Especially digital subtraction and reconstruction can be applied in many aspects of clinical practice and research. Electronic transfer of images enables filmless dental hospital and teleradiology/teledentistry system. Since the first image management and communications system (IMACS) for dentomaxillofacial radiology was reported in 1992, IMACS in dental hospital has been increasing. Meanwhile, researches about computer-assisted diagnosis, such as structural analysis of bone trabecular patterns of mandible, feature extraction, automated identification of normal landmarks on cephalometric radiograph and automated image analysis for caries or periodontitis, have been performed actively in the last decade. Further developments in digital radiographic imaging modalities, image transmission system, imaging processing and automated analysis software will change the traditional clinical dental practice in the 21st century.

The interest in equine dentistry has significantly increased in the last 15 years. On the part of the veterinarians as well as of the horse owners there is a strong attention to the topic. The aim of the questionnaire was to investigate amongst horse owners what their level of information and preferences about dental treatment are and how they are implemented. The questionnaire was translated into the three national languages and included 20 questions about level and sources of information, frequency of treatments and the horse owner's stance over sedation of the animals. With a return rate of 45% (1'466 of 3'250 sent questionnaires) significant conclusions could be drawn. Horse owners showed a strong demand for clarification regarding tooth problems, the causes, consequences and methods of treatment. More than half of the owners considered themselves not well informed. The treating person was in 66.7% a veterinarian with a special education. Horse owners indicated that information circulated most frequently by word of mouth recommendations and they explicitly wished information from professional and reliable sources. The questionnaire provided a clear result about current equine dental treatments. We suggest that they should be performed by veterinarians only with a special education.

Acetylation of histone and non-histone proteins alters gene expression and induces a host of cellular effects. The acetylation process is homeostatically balanced by two groups of cellular enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs). HAT activity relaxes the structure of the human chromatin, rendering it transcriptionally active, thereby increasing gene expression. In contrast, HDAC activity leads to gene silencing. The enzymatic balance can be \\'tipped\\' by histone deacetylase inhibitors (HDACi), leading to an accumulation of acetylated proteins, which subsequently modify cellular processes including stem cell differentiation, cell cycle, apoptosis, gene expression, and angiogenesis. There is a variety of natural and synthetic HDACi available, and their pleiotropic effects have contributed to diverse clinical applications, not only in cancer but also in non-cancer areas, such as chronic inflammatory disease, bone engineering, and neurodegenerative disease. Indeed, it appears that HDACi-modulated effects may differ between \\'normal\\' and transformed cells, particularly with regard to reactive oxygen species accumulation, apoptosis, proliferation, and cell cycle arrest. The potential beneficial effects of HDACi for health, resulting from their ability to regulate global gene expression by epigenetic modification of DNA-associated proteins, also offer potential for application within restorative dentistry, where they may promote dental tissue regeneration following pulpal damage.

This review is intended to provide the ceramic engineer with information about the history and current use of ceramics in dentistry, contemporary research topics, and potential research agenda. Background material includes intra-oral design considerations, descriptions of ceramic dental components, and the origin, composition, and microstructure of current dental ceramics. Attention is paid to efforts involving net-shape processing, machining as a forming method, and the analysis of clinical failure. A rationale is presented for the further development of all-ceramic restorative systems. Current research topics receiving attention include microstructure/processing/property relationships, clinical failure mechanisms and in vitro testing, wear damage and wear testing, surface treatments, and microstructural modifications. The status of the field is critically reviewed with an eye toward future work. Significant improvements seem possible in the clinical use of ceramics based on engineering solutions derived from the study of clinically failed restorations, on the incorporation of higher levels of "biomimicry" in new systems, and on the synergistic developments in dental cements and adhesive dentin bonding.

In dentistry, Radio Visio Graphy was introduced as a first electronic dental x-ray imaging modality in 1989. Thereafter, many types of direct digital radiographic systems have been produced in the last decade. They are based either on charge-coupled device (CCD) or on storage phosphor technology. In addition, new types of digital radiographic system using amorphous selenium, image intensifier etc. are under development. Advantages of digital radiographic system are elimination of chemical processing, reduction in radiation dose, image processing, computer storage, electronic transfer of images and so on. Image processing includes image enhancement, image reconstruction, digital subtraction, etc. Especially digital subtraction and reconstruction can be applied in many aspects of clinical practice and research. Electronic transfer of images enables filmless dental hospital and teleradiology/teledentistry system. Since the first image management and communications system (IMACS) for dentomaxillofacial radiology was reported in 1992, IMACS in dental hospital has been increasing. Meanwhile, researches about computer-assisted diagnosis, such as structural analysis of bone trabecular patterns of mandible, feature extraction, automated identification of normal landmarks on cephalometric radiograph and automated image analysis for caries or periodontitis, have been performed actively in the last decade. Further developments in digital radiographic imaging modalities, image transmission system, imaging processing and automated analysis software will change the traditional clinical dental practice in the 21st century.
Full Text Available Despite numerous technological and medical developments achieved in recent years, a significant amount of occupational health problems still exist in modern dentistry. The risk of eye injury is mostly attributed to the use of high-speed hand pieces and ultrasonic devices. A dental clinic may be the source of eye-related infection and injury because of mechanical, chemical, microbiological and electromagnetic irritants. Accidents may cause facial injuries that involve eyes of the clinicians, patients as well as dental assistants. Eye injuries can vary from mild irritation to blindness. The use of eye protection tools, such as protective goggles and visors, reduces the risk of eye damage or complete loss of vision while working with dangerous and floating materials. Therefore, all precautions should be taken, even when performing common procedures for which the risk expectancy is relatively low. Clinicians should be aware that they are also responsible for providing adequate protection for their assistants and patients, as well as themselves.

Modern conceptions of corporate personhood have spurred considerable debate about the rights that society should afford business organizations. Across eight experiments, we compare lay perceptions of how corporations and people use rights, and also explore the consequences of these judgments. We find that people believe corporations, compared to humans, are similarly likely to use rights in protective ways that prevent harm but more likely to use rights in nonprotective ways that appear independent from-or even create-harm (Experiments 1a through 1c and Experiment 2). Because of these beliefs, people support corporate rights to a lesser extent than human rights (Experiment 3). However, people are more supportive of specific corporate rights when we framed them as serving protective functions (Experiment 4). Also as a result of these beliefs, people attribute greater ethical responsibility to corporations, but not to humans, that gain access to rights (Experiments 5a and 5b). Despite their equitability in many domains, people believe corporations and humans use rights in different ways, ultimately producing different reactions to their behaviors as well as asymmetric moral evaluations.

Full Text Available To identify, appraise and summarize existing knowledge and knowledge gaps in practice-relevant questions in pediatric dentistry.A systematic mapping of systematic reviews was undertaken for domains considered important in daily clinical practice. The literature search covered questions in the following domains: behavior management problems/dental anxiety; caries risk assessment and caries detection including radiographic technologies; prevention and non-operative treatment of caries in primary and young permanent teeth; operative treatment of caries in primary and young permanent teeth; prevention and treatment of periodontal disease; management of tooth developmental and mineralization disturbances; prevention and treatment of oral conditions in children with chronic diseases/developmental disturbances/obesity; diagnosis, prevention and treatment of dental erosion and tooth wear; treatment of traumatic injuries in primary and young permanent teeth and cost-effectiveness of these interventions. Abstracts and full text reviews were assessed independently by two reviewers and any differences were solved by consensus. AMSTAR was used to assess the risk of bias of each included systematic review. Reviews judged as having a low or moderate risk of bias were used to formulate existing knowledge and knowledge gaps.Out of 81 systematic reviews meeting the inclusion criteria, 38 were judged to have a low or moderate risk of bias. Half of them concerned caries prevention. The quality of evidence was high for a caries-preventive effect of daily use of fluoride toothpaste and moderate for fissure sealing with resin-based materials. For the rest the quality of evidence for the effects of interventions was low or very low.There is an urgent need for primary clinical research of good quality in most clinically-relevant domains in pediatric dentistry.

MEDICOL (Medicine and Dentistry Integrated Curriculum Online) provides a variety of Web-based resources that act as important adjuncts to all the teaching components of the medical and dental undergraduate curriculum. It uses WebCT, a course-management system, to provide the following educational functions: (1) track students' progress and present course information such as time-tables, learning objectives, handout materials, images, references, course assignments, and evaluations; (2) promote student-to-student and student-to-instructor interactions (through e-mail and bulletin boards); and (3) deliver self-directed learning components, including weekly self-assessment quizzes that provide immediate feedback and multimedia learning modules (clinical skills, radiology, evidence-based medicine, etc.). The University of British Columbia Faculties of Medicine and Dentistry feature a problem-based learning (PBL) curriculum in which students access many of the same tools they will utilize in their professional practice. In the PBL curriculum, students must access the relevant clinical data and educational resources. A MEDICOL site has also been developed for medical students to use during their rural family practice, a four- to six-week experience in the summer after their second year. This site has been designed to be a supplemental learning environment for not only these students, but also for their physician preceptors. It is intended to foster communication among participants, bring new resources to the rural setting, and allow preceptors to develop their Internet skills with the help of students who are already familiar with the electronic environment. The MEDICOL sites enable the exchange of information about the learning issues between, as well as within, tutorial groups. MEDICOL also provides students with faculty-reviewed resources that are listed online; multimedia presentations; and access to histology, radiology, and pathology images through an online image

Publication retraction is a mechanism to preserve the scientific literature against publications that contain seriously flawed or erroneous data, redundant publication, plagiarism, unethical research, and other features that compromise the integrity of science. An increase in the occurrence of retractions in recent years has been reported. Nevertheless, there is scarce information on this topic concerning publications in dentistry and related specialties. Thus, this study aimed to investigate retracted papers published in dental journals. Data collection included an exploratory search in PubMed and a specific search in SCImago Journal Rank indexed journals, complemented by the cases reported on the Retraction Watch website and in PubMed. All 167 dental journals included in SCImago were searched for identification of retracted articles up to March 2016. The selected retracted articles and their corresponding retraction notices were recorded and assessed for classification according to the reason for retraction and other additional information. Forty of the 167 journals scrutinised at SCImago (23.9%) had at least one retracted article, and four additional journals were identified from the Retraction Watch website. A total of 72 retracted found were retracted for the reasons: redundant publication (20.8%), plagiarism (18.1%), misconduct (13.8%), overlap (13.6%) and honest error (9.7%). Higher number of retractions were reported in those journals with cites/doc <2.0-n = 49 (74.2%). The types of studies were mainly laboratory studies (34.7%), case reports (22.2%) and review articles (13.9%). The approach to ethical problems in papers published in dental scientific journals is still incipient; retractions were mostly due to the authors' malpractice and were more frequently related to journals with less impact.

Full Text Available Dental implants have been considered to be a successful treatment modality. Recently, achieving a good osseointegration is not the ultimate goal for the restorative dentist. Successful implant treatment demands the best gingival esthetic success along with stability and function of the implant. This study was performed to obtain answers to some controversial points pertaining to esthetics and function of implants in maxilla. Immediate flapless implantation into the extraction sockets in maxillary anterior zone is an emerging treatment option in dentistry- the esthetic success of which was in debate for long. The proposed study compared the esthetic success of immediate flapless implants (ILA, to immediate implants with the need for flap (ILB and, delayed implants (DSL in single tooth restorations, in the anterior region of the maxilla. The other aim of the study was to find out if any relation exists between the interproximal crestal bone height and papilla height. Analysis was done irrespective of treatment procedure in the same study group using periodontal sounding and radiographs to find out the relation. From the study involving 106 participants, including 21 ILA, 22 ILB and 63 DSL cases, we received highest papillary index score of 2.6 average from group ILA, followed by ILB and DSL, after 3 months of prosthetic loading. From the periodontal sounding and radiographic study it was evident that, when the distance between the base of the contact point of crowns and height of interproximal bone was less than 5, the papilla was present 100 % of the time, but when the distance increased to 6 and more than 7 mm, the papilla was present only 46.5 and 24 percentage of the time respectively.
Full Text Available The purpose of this study is to examine the moderating effect of earning management on corporate governance mechanism, ownership structure, and external auditor toward corporate social responsibility disclosure. This study finds that the increase of ownership structure (foreign ownership and institutional ownership will increase corporate social responsibility disclosure. However corporate governance mechanism and external auditor is not affecting corporate social responsibility disclosure. Furthermore, this study provides additional empirical evidence for agency theory especially agency cost, that corporate governance mechanism, ownership structure, and Big Four audit firm do not have an effective role as agency cost to prevent or decrease earning management practice.

Consensus guidelines are useful to improve clinical decision making. Therefore, the methodological evaluation of these guidelines is of paramount importance. Low quality information may guide to inadequate or harmful clinical decisions. To evaluate the methodological quality of consensus guidelines published in implant dentistry using a validated methodological instrument. The six implant dentistry journals with impact factors were scrutinised for consensus guidelines related to implant dentistry. Two assessors independently selected consensus guidelines, and four assessors independently evaluated their methodological quality using the Appraisal of Guidelines for Research & Evaluation (AGREE) II instrument. Disagreements in the selection and evaluation of guidelines were resolved by consensus. First, the consensus guidelines were analysed alone. Then, systematic reviews conducted to support the guidelines were included in the analysis. Non-parametric statistics for dependent variables (Wilcoxon signed rank test) was used to compare both groups. Of 258 initially retrieved articles, 27 consensus guidelines were selected. Median scores in four domains (applicability, rigour of development, stakeholder involvement, and editorial independence), expressed as percentages of maximum possible domain scores, were below 50% (median, 26%, 30.70%, 41.70%, and 41.70%, respectively). The consensus guidelines and consensus guidelines + systematic reviews data sets could be compared for 19 guidelines, and the results showed significant improvements in all domain scores (p dentistry journals is needed. The findings of the present study may help researchers to better develop consensus guidelines in implant dentistry, which will improve the quality and trust of information needed to make proper clinical decisions.

Previous research has suggested that antidepressants can be used in oral health care. The aim of this systematic review was to search for scientific evidence of the efficacy of the use of antidepressants in dentistry. The clinical question was as follows (PICO question): dentistry patients (Patients); antidepressants (Intervention); no use or placebo or other drug (Comparison); and efficacy in oral health problems (Outcome). An electronic search was conducted in seven databases, as well as a manual search without restriction regarding language and date of publication. Two independent reviewers selected studies based on eligibility criteria, extracted data and assessed methodological quality based on the PEDro scale. The PROSPERO record is number CRD42016037442. A total of 15 randomized controlled trials were associated with the use of antidepressants to control chronic or acute pain in dentistry, among other conditions such as bruxism and burning mouth syndrome. The most commonly used drug in clinical trials was amitriptyline (more than 50% of studies). Antidepressants may be effective in dentistry for acute and chronic pain, but there is a large amount of methodological heterogeneity among the evaluated studies. In summary, there is rationality for the indication of this class of medicine in dentistry in specific clinical situations. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

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.

What differentiates truly great corporate strategies from the merely adequate? How can executives at the corporate level create tangible advantage for their businesses that makes the whole more than the sum of the parts? This article presents a comprehensive framework for value creation in the multibusiness company. It addresses the most fundamental questions of corporate strategy: What businesses should a company be in? How should it coordinate activities across businesses? What role should the corporate office play? How should the corporation measure and control performance? Through detailed case studies of Tyco International, Sharp, the Newell Company, and Saatchi and Saatchi, the authors demonstrate that the answers to all those questions are driven largely by the nature of a company's special resources--its assets, skills, and capabilities. These range along a continuum from the highly specialized at one end to the very general at the other. A corporation's location on the continuum constrains the set of businesses it should compete in and limits its choices about the design of its organization. Applying the framework, the authors point out the common mistakes that result from misaligned corporate strategies. Companies mistakenly enter businesses based on similarities in products rather than the resources that contribute to competitive advantage in each business. Instead of tailoring organizational structures and systems to the needs of a particular strategy, they create plain-vanilla corporate offices and infrastructures. The company examples demonstrate that one size does not fit all. One can find great corporate strategies all along the continuum.

Clinics today specialize in health repair services similar to car repair shops; procedures and prices are standardized, regulated, and inflexibly uniform. Clinics of the future have to become Health Care Centers in order to be more respected and more effective corporate neighbors in offering outreach services in health education and preventive health care. The traditional concept of care for health is much broader than repair management and includes the promotion of lay health competence and responsibility in healthy social and natural environments. The corporate profile and ethics of the clinic as a good and competitive local neighbor will have to focus on [a] better personalized care, [b] education and services in preventive care, [c] direct or web-based information and advice for general, seasonal, or age related health risks, and on developing and improving trustworthy character traits of the clinic as a corporate person and a good neighbor.

This article explains the fundamentals of evidence-based dentistry for the dentist. Evidence-based dentistry is a discipline whose primary participant is the translational researcher. Recent developments have emphasized the importance of this discipline (clinical and translational research) for improving health care. The process of evidence-based dentistry is the reciprocation of new and existing evidence between dentists and quantitative and qualitative researchers, facilitated by the translational researcher. The product of this reciprocation is the clinical practice guideline, or best evidence, that provides the patient options in choosing treatments or services. These options are quantified and qualified by decision, utility, and cost data. Using shared decision-making, the dentist and patient arrive at a mutual understanding of which option best meets an acceptable and preferred treatment course that is cost effective. This option becomes the clinical decision.

In recent years, clinician and dentist's esthetic demand in dentistry have increased rapidly, driven by an enhanced awareness of beauty and esthetics. The ultimate goal in modern restorative dentistry is to achieve "white" and "pink" esthetics in esthetically important zones. "White esthetics" is the natural dentition or the restoration of dental hard tissues with suitable materials. "Pink esthetics" refers to the surrounding soft-tissues, which includes the interdental papilla and gingiva that can enhance or diminish the esthetic result. Reconstruction of the lost interdental papilla is one of the most challenging and least predictable problems. Restoration and maintenance of these tissues with adequate surgical and prosthetic techniques are a real challenge in modern esthetic dentistry. Treatment of marginal tissue recession, excessive gingival display, deficient ridges, ridge collapse, and esthetic defects around teeth and implants are some of the esthetic problems associated with the interdental papilla that have to be corrected in todays scenario which has been discussed in this review.
This article illustrates three examples supporting the modern value of early writings in dentistry and medicine. First, by studying cases described in works published long before the era of genetic science, we are able to develop new hypotheses about familial conditions and their genetic roots. Tooth transposition is presented as an example. Second, old writings may lead us to valuable historical insights and perspectives in medicine that can be revealed only in retrospective analysis. An example of this kind of historical analysis uncovers why dentistry became unnaturally separated from mainstream medicine in the 19th century. Third, early writings become keys to unlocking forgotten knowledge that enriches our understanding of historically significant people and events. The discovery of Norman Kingsley's long forgotten pyrographic paintings after Rembrandt portraits is used as an example. Libraries, the traditional custodians of these valued old texts, must continue to be supported, and not undermined by the paperless digital revolution.

Nanotechnology is emerging as an interdisciplinary field that is undergoing rapid development and has brought about enormous changes in medicine and dentistry. Nanomaterial-based design is able to mimic some of the mechanical and structural properties of native tissue and can promote biointegration. Nanotechnology has various applications in dentistry, including dentition renaturalization, therapy for dentin hypersensitivity, complete orthodontic realignment in a single visit, covalently bonding diamondized enamel, enhancing properties of root canal sealers, and continuous oral health maintenance using mechanical dentifrobots. A range of synthetic nanoparticles such as hydroxyapatite, bioglass, titanium, zirconia, and silver nanoparticles are proposed for dental restoration. This review focuses on the developments in the field of nanomaterials in dentistry in the form of tissue regeneration materials, implantable devices, nanocomposites, endodontic sealers etc. and issues of patient safety.

Transcutaneous electric nerve stimulation (TENS) is a non-pharmacological method which is widely used by medical and paramedical professionals for the management of acute and chronic pain in a variety of conditions. Similarly, it can be utilized for the management of pain during various dental procedures as well as pain due to various conditions affecting maxillofacial region. This review aims to provide an insight into clinical research evidence available for the analgesic and non analgesic uses of TENS in pediatric as well as adult patients related to the field of dentistry. Also, an attempt is made to briefly discuss history of therapeutic electricity, mechanism of action of TENS, components of TENs equipment, types, techniques of administration, advantages and contradictions of TENS. With this we hope to raise awareness among dental fraternity regarding its dental applications thereby increasing its use in dentistry. Key words:Dentistry, pain, TENS.

Full Text Available Background Sedation in dentistry is a controversial topic given the variety of opinions regarding its safe practice. Aims This article evaluates the various techniques used to administer sedation in dentistry and specific methods practiced to form a recommendation for clinicians. Methods An extensive literature search was performed using PubMed, Medline, Google Scholar, Google, and local library resources. Results Most of the literature revealed a consensus that light sedation on low-risk American Society of Anesthesiologists (ASA groups, that is ASA I, and possibly II, is the safest method for sedation in a dental outpatient setting. Conclusion Formal training is essential to achieve the safe practice of sedation in dentistry or medicine. The appropriate setting for sedation should be determined as there is an increased risk outside the hospital setting. Patients should be adequately assessed and medication titrated appropriately, based on individual requirements.
Dentistry is highly energy and resource intensive with significant environmental impact. Factors inherent in the profession such as enormous electricity demands of electronic dental equipment, voluminous water requirements, environmental effects of biomaterials (before, during and after clinical use), the use of radiation and the generation of hazardous waste involving mercury, lead etc have contributed towards this. With rising temperatures across the world due to global warming, efforts are being made worldwide to mitigate the effects of environmental damage by resorting to sustainability concepts and green solutions in a myriad of ways. In such a scenario, a professional obligation and social responsibility of dentists makes it imperative to transform the practice of dentistry from a hazardous to a sustainable one, by adopting environmental-friendly measures or 'green dentistry'. The NHS in the UK has been proactive in implementing sustainability in healthcare by setting targets, developing guidance papers, initiating steering groups to develop measures and implementing actions through its Sustainable Development Unit (SDU). Such sustainable frameworks, specific to dentistry, are not yet available and even the scientific literature is devoid of studies in this field although anecdotal narratives abound. Hence this paper attempts to present a comprehensive evaluation of the existing healthcare sustainability principles, for their parallel application in the field of dentistry and lays out a blueprint for integrating the two main underlying principles of sustainability - resource use efficiency and eliminating or minimising pollution - in the day-to-day practice. The article also highlights the importance of social values, community care, engaging stakeholders, economic benefits, developing policy and providing leadership in converting the concept of green dentistry into a practised reality.

The aim of this study was to re-examine the teaching of geriatric dentistry in the USA dental schools, to identify curriculum content and compare the findings to previous reports. All dental schools in the United States were contacted via email with a questionnaire to assess the teaching of geriatric dentistry. Non-responding schools were sent a minimum of three reminder emails to complete the survey. A statistical analysis was performed. Descriptive statistics were conducted to profile the variables of interest. Bivariate analysis was performed to explore if any of the variables were related using Fisher's exact test, non-parametric Wilcoxon rank-sum test and the Kruskal-Wallis test. Fifty-six of the 67 dental schools completed the questionnaire. Geriatric dentistry was taught in all dental schools; for 92.8%, the course was compulsory. We found that 62.5% were teaching it as an independent course, 25% as an organised series of lectures and 8.9% as occasional lectures in parts of other courses. Clinically, 84.2% have some form of compulsory education in geriatric dentistry. Public schools were marginally associated with an increased interest in expanding the geriatric dentistry curriculum (P = .078). No differences were found between these variables and school location. Geriatric dentistry is now required in 92.8% of dental schools. The teaching of traditional topics has not changed much; however, the number of gerontological topics has increased. Clinical teaching needs to be expanded, as in only 57.1% of schools was it a requirement. The ageing imperative will require research to determine the impact of teaching on services to the geriatric community. © 2017 John Wiley & Sons A/S and The Gerodontology Association.

Interest in the use of engineered nanomaterials (ENMs) as either nanomedicines or dental materials/devices in clinical dentistry is growing. This review aims to detail the ultrafine structure, chemical composition, and reactivity of dental tissues in the context of interactions with ENMs, including the saliva, pellicle layer, and oral biofilm; then describes the applications of ENMs in dentistry in context with beneficial clinical outcomes versus potential risks. The flow rate and quality of saliva are likely to influence the behavior of ENMs in the oral cavity, but how the protein corona formed on the ENMs will alter bioavailability, or interact with the structure and proteins of the pellicle layer, as well as microbes in the biofilm, remains unclear. The tooth enamel is a dense crystalline structure that is likely to act as a barrier to ENM penetration, but underlying dentinal tubules are not. Consequently, ENMs may be used to strengthen dentine or regenerate pulp tissue. ENMs have dental applications as antibacterials for infection control, as nanofillers to improve the mechanical and bioactive properties of restoration materials, and as novel coatings on dental implants. Dentifrices and some related personal care products are already available for oral health applications. Overall, the clinical benefits generally outweigh the hazards of using ENMs in the oral cavity, and the latter should not prevent the responsible innovation of nanotechnology in dentistry. However, the clinical safety regulations for dental materials have not been specifically updated for ENMs, and some guidance on occupational health for practitioners is also needed. Knowledge gaps for future research include the formation of protein corona in the oral cavity, ENM diffusion through clinically relevant biofilms, and mechanistic investigations on how ENMs strengthen the tooth structure.

Economic evaluation (EE) studies have been undertaken in dentistry since the late 20th century because economic data provide additional information to policy makers to develop guidelines and set future direction for oral health services. The objectives of this study were to assess the methodological quality of EEs in oral health. Electronic searching of Ovid MEDLINE, the Cochrane Library, and the NHS Economic Evaluation Database from 1975 to 2013 were undertaken to identify publications that include costs and outcomes in dentistry. Relevant reference lists were also searched for additional studies. Studies were retrieved and reviewed independently for inclusion by 3 authors. Furthermore, to appraise the EE methods, 1 author applied the Drummond 10-item (13-criteria) checklist tool to each study. Of the 114 publications identified, 79 studies were considered full EE and 35 partial. Twenty-eight studies (30%) were published between the years 2011 and 2013. Sixty-four (53%) studies focused on dental caries prevention or treatment. Median appraisal scores calculated for full and partial EE studies were 11 and 9 out of 13, respectively. Quality assessment scores showed that the quality of partial EE studies published after 2000 significantly improved (P = 0.02) compared to those published before 2000. Significant quality improvement was not found in full EE studies. Common methodological limitations were identified: absence of sensitivity analysis, discounting, and insufficient information on how costs and outcomes were measured and valued. EE studies in dentistry increased over the last 40 y in both quantity and quality, but a number of publications failed to satisfy some components of standard EE research methods, such as sensitivity analysis and discounting. © International & American Associations for Dental Research 2015.
Full Text Available Italian National Health Service (INHS provides hospital, district and preventive cares in many medical areas but dental cares are a small part of all treatments provided. It is estimated that it only answers a 5% of need. In Italy dental treatments are predominantly provided by private practitioners: it means little access equity to cares. Nowadays, just 1,5% of the INHS expense is aimed at public dentistry because most of dental cares are believed “not urgent”. Why oral diseases are not considered so invalidating to have relief in INHS? They should get the same attention of the other pathologies because they worsen the quality of life in term of physical and psychological health. Need of public dentistry performances has recently increased, as confirmed by larger and larger waiting lists: it has revealed the growing dental need of the weakest part of the Italian society that, because of economic, social, cultural reasons, can hardly afford private cares (private practitioners are now facing a crisis, too. Dentists’ ethical code is not essentially different from physicians’ one even if most of the oral pathology is not worrying about patients’ life. “Bioethics in Dentistry” (2005, an issue by the National Bioethics Committee says: “public dentistry is actually absent in helping the weak part of the society. Just consider that in Italy oral cares are not included in Essential Care Levels (ECL and they are not provided by Local Health Authorities whereas requirements to State exams include minimum tooth number and good oral health, because of the high importance of oral wellness.

Evidence-based dentistry (EBD) can help provide the best treatment option for every patient, however, its implementation in restorative dentistry is very limited. This study aimed at assessing the barriers preventing the implementation of EBD among dental undergraduate and graduate students in Montreal, and explore possible solutions to overcome these barriers. A cross-sectional survey was conducted by means of a paper format self-administrated questionnaire distributed among dental students. The survey assessed the barriers and potential solutions for implementation of an evidence-based practice. Sixty-one students completed the questionnaire. Forty-one percent of respondents found evidence-based literature to be the most reliable source of information for restorative treatment planning, however, only 16% used it. They considered that finding reliable information was difficult and they sometimes encountered conflicting information when consulting different sources. Dental students had positive attitudes towards the need for better access to evidence-based literature to assist learning and decision making in restorative treatment planning and to improve treatment outcomes. Even for dentists trained in EBD, online searching takes too much time, and even though it can provide information of better quality than personal intuition, it might not be enough to identify the best available evidence. Even though dental students are aware of the importance of EBD in restorative dentistry they rarely apply the concept, mainly due to time constraints. For this reason, implementation of EBD would probably require faster access to evidence-based knowledge. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Full Text Available Children’s dental anxiety has been of great worry for many years and it is still a barrier for dental care. According to recent guidelines for oral health prevention in childhood, additional strategies for a preventive care should be applied for pediatric patients. So it’s important to encourage pediatric dentists to develop a “child-friendly” environment for treating children. Environmental elements that produce positive feelings can reduce anxiety. The analysis of environmental design and features applied in Pediatric Dentistry Unit, Department of Oral and Maxillo-facial sciences, Sapienza University of Rome, highlighted special attention to the aspects supporting sensory conditions (colors, light, spatial organization; reassurance strategies (decorations,dental team attire, drawings; anxiety control strategies (playing area, TV, comics, toys; behavioral management strategies (positive reinforcement, modeling; in-formation (brochures, posters.

As the use of information and communication technology (ICT) becomes more widespread in dentistry the risk of breaching electronic commerce laws and patient confidentiality increases. It is necessary to be aware of the responsibilities internet usage entails, especially within a dental practice where the protection of patient information is of the utmost importance. More should be done to outline the various precautions that should be taken to ensure ICT security within the professional domain, as it would appear dentistry has been neglected with regard to receiving the proper ICT education, training and support systems.
Virtual reality is a computer based technology linked with the future of dentistry and dental practice. The virtual articulator is one such application in prosthetic and restorative dentistry based on virtual reality that will significantly reduce the limitations of the mechanical articulator, and by simulation of real patient data, allow analyses with regard to static and dynamic occlusion as well as to jaw relation. It is the purpose of this article to present the concepts and strategies for a future replacement of the mechanical articulator by a virtual one. Also, a brief note on virtual reality haptic system has been highlighted along with newly developed touch enabled virtual articulator. PMID:25177664
Basic requirement for an optimized application of radiation in dentistry is a qualified dosimetry. The paper introduces into new dosimetry techniques based on solid state phenomena, such as luminescence an exoelectron emission, which, in case of dentistry, appear superior to conventional methods such as film and ionization chamber dosimetry. Advantages of the TLDs dosimeters, such as miniature detector volume, dynamic detection range, tissue equivalence etc., and their dosimetric possibilities are described together with hints on operational problems with respect to achieving high dosimetric measurement accuracy.

This study investigates student and stakeholder perceptions of the role of the dental hygienist in Nepal. The impact of these perceptions on the professionalization of dental hygienists is described whilst exploring the consequences for oral health workforce planning. Dentistry and dental hygiene students from one dental college in Nepal were asked to complete an anonymous questionnaire; 171 students returned the questionnaire containing a mix of forced response and open-ended items. Quantitative data were analysed using SPSS ® 22. These data were complemented with qualitative information from survey open questions and from semi-structured interviews with key informants from several relevant organizations. Qualitative data were manually analysed and coded. Data were triangulated to contextualize quantitative data. A high level of positive regard for the role of the dental hygienist in Nepal was evident amongst dentistry and dental hygiene students in this college. Both groups believe that the dental hygienist can play a major role in raising oral health awareness in Nepal. The scope of practice of the dental hygienist was unclear with issues surrounding the scope of practice and reports of illegal practice by dental hygienists. Significant differences (P dental hygiene and dentistry students in relation to their opinion regarding independent practice and the need of supervision by a dentist. Supervision of the dental hygienist by dentists and issues surrounding the scope of practice are polarizing the relationship between dentists, dental hygienists and the relevant professional organizations. This could hinder cooperation between these oral health professionals and might lead to underutilization of the dental hygienist. To improve the understanding about the roles of each oral health professional, establishing functional relationships and intraprofessional education involving dentistry and dental hygiene students needs to be introduced. This will benefit the

Full Text Available A healthy mouth is closely linked to general health and quality of life. Oral Health Education actions are extremely important in encouraging the practice of oral hygiene by the population. It is essential that actions related to oral health issues in hospitalized patients be developed by means of educational and preventive methods. In this context, students from the Extension Project of the Dentistry Course of the Federal University of Ceará saw the needs of patients of Dr. José Frota Institute for the collective actions in oral hygiene. The activities began in November 2007, being held on Sundays by 15 students divided into groups with regard to implementing the feelings of teamwork and the exchange of fun activities for the practice of solidarity. Guidelines on oral hygiene were made through the use of macro models, folders, mirrors, fluoridated toothpastes and brushes of teeth. All observations were recorded on a specific form - since the sociodemographic data to the oral health conditions in order to know the reality under an epidemiology look and make it possible to propose oral health policy in the Instituition. A total of 385 patients were assisted in two years of operation. It was founded that the prolonged hospitalization and/or obstruction of the self implementation means that oral hygiene is not prioritized, requiring the implementation of educational activities in a work environment even uncommon to the surgeon-dentist, but very promising for the designs of Dentistry, the hospital environment.

Use of ceramics and polymers continues to dominate clinical procedures in modern dentistry. Polymers have provided the basis for adhesives, tissue void fillers, and artificial replacements for whole teeth. They have been remarkably effective in the clinic at restoration of major dental functions after damage or loss of teeth. With the rapid development of polymer science, dental materials science has significantly lagged behind in harnessing these advanced polymer products. What they offer is new and unique properties superior to traditional polymers and crucially a range of properties that more closely match natural biomaterials. Therefore, we should pursue more vigorously the benefits of advanced polymers in dentistry. In this review, we highlight how the latest generation of advanced polymers will enhance the application of materials in the dental clinic using numerous promising examples. Polymers have a broad range of applications in modern dentistry. Some major applications are to construct frameworks that mimic the precise structure of tissues, to restore tooth organ function, and to deliver bioactive agents to influence cell behavior from the inside. The future of polymers in dentistry must include all these new enhancements to increase biological and clinical effectiveness beyond what can be achieved with traditional biomaterials. © 2014 John Wiley & Sons A/S.

Stem cells can self-renew and produce different cell types, thus providing new strategies to regenerate missing tissues and treat diseases. In the field of dentistry, adult mesenchymal stem/stromal cells (MSCs) have been identified in several oral and maxillofacial tissues, which suggests that the oral tissues are a rich source of stem cells, and oral stem and mucosal cells are expected to provide an ideal source for genetically reprogrammed cells such as induced pluripotent stem (iPS) cells. Furthermore, oral tissues are expected to be not only a source but also a therapeutic target for stem cells, as stem cell and tissue engineering therapies in dentistry continue to attract increasing clinical interest. Part I of this review outlines various types of intra- and extra-oral tissue-derived stem cells with regard to clinical availability and applications in dentistry. Additionally, appropriate sources of stem cells for regenerative dentistry are discussed with regard to differentiation capacity, accessibility and possible immunomodulatory properties.

The objective was to show the necessity and the importance of the training and formation of the dentist in radioprotection according to the recent proposal for technical regulations 'Radiological protection directrixes in Medical and Dentistry radiodiagnostic' of the Secretaria do Vigilancia Sanitaria of Ministerio da Saude (SVSMS). This regulation establishes basic standards to radioprotection in the medical and dentistry areas, including principles, limits, obligations and basic controls for the man and environment protection, versus possible improper effects caused by the use of ionizing radiation sources. An analysis of the discipline programs of the Dentistry Schools of Rio de Janeiro state indicates that they show a little or none preoccupation by the radiological protection, which was confirmed through a survey applied toward responsible professors by department or radiology service to the dentistry Schools. This work suggests the creation or adaptation of the existing disciplines introducing radioprotection and images quality in radiodiagnostic, to improve, complement and to make uniform the formation of future dentists optimizing the solution of the identified problems.

This paper describes how a relatively new style of online learning, a massive open online course (MOOC), may be used to raise aspirations and widen participation in dental professions. A MOOC was designed and run with the aim of engaging prospective students of dental professions in learning and discussion. Over 4,200 learners signed up, and 450 students fully completed this first run of the course. The course attracted a significantly younger demographic than is typical for MOOCs, and nearly a third who responded to the pre-course survey reported they were doing the course specifically as preparation for a dental degree. The approach also provided a platform for public engagement on the subject of dentistry with participants, both dental professionals and members of the public, contributing to discussion around the learning materials from around the world, providing a unique, internationalised perspective of oral healthcare for learners. This study shows that there is genuine potential for MOOCs to involve people from disadvantaged backgrounds in higher education by offering free, accessible, enjoyable and engaging educational experiences. The data gives us cautious optimism that these courses can play a significant role within a platform of other WP interventions.

Various caries prevention and repair strategies are reviewed in this article ranging from the use of fluoride to nanohydroxyapatite particles. Several of the strategies which combine fluoride and calcium and phosphate treatments have both in vitro and in vivo data showing them to be efficacious if the surface integrity of the lesion is not breached. Once this has occurred, the rationale for cutting off the nutrient supplies to the pathogenic bacteria without the removal of the infected dentine, a noninvasive restorative technique, is discussed using existing clinical studies as examples. Finally two novel noninvasive restorative techniques using fluorohydroxyapatite crystals are described. The need for clinical data in support of emerging caries-preventive and restorative strategies is emphasized. 2015 S. Karger AG, Basel

According to the classical theory managers are responsible to owners (stockholders and their obligation is to pursue the goal of maximizing the profit. According to the other, stakeholder theory, the interests of all corporate stakeholders, all those affected by business, not only stockholders, must be taken in consideration. In the paper these two theories are subject of thorough ethical analysis.

This paper examines the relationships between corporate governance mechanisms and risk disclosure behavior using a sample of Canadian publicly-traded companies (TSX 230. Results show that Canadian public companies are more likely to disclose risk management information over and above the mandatory risk disclosures, if they are larger in size and if their boards of directors have more independent members. Minority voting control ownership structures appear to negatively impact risk disclosure and CEO incentive compensation shows mixed results. The paper concludes that more research is needed to further assess the impact of various governance mechanisms on corporate risk management and disclosure behavior.

Corporate and philanthropic involvement in the peace movement is growing. In considering medical peace groups as examples, we have studied the ways that corporate and philanthropic funding have shaped the course of activism. Our methods have included: review of the Foundations Grant Index from 1974-1983; analysis of corporations' and foundations' criteria for grants in the categories of peace, arms control, and disarmament; interviews with leaders of activist organizations and with foundation officials; and our own experiences in the peace movement. Corporate interests in preventing nuclear war stem from a concern for global stability in which world markets may expand, and from a hope to frame issues posed by the peace movement in a way that will not challenge basic structures of power and finance. Several general features make peace groups respectable and attractive to philanthropies; an uncritical stance toward corporate participation in the arms race; a viewpoint that the main danger of nuclear war stems from a profound, bilateral conflict between the United States and the Soviet Union; and a single-issue focus that does not deal with the many related problems reflecting the injustices of capitalism. The two major medical groups working for peace, Physicians for Social Responsibility (PSR) and International Physicians for the Prevention of Nuclear War (IPPNW), have accomplished many goals; however, their adherence to subtle criteria of respectability and their dependence on philanthropic funding have limited the scope of their activism. The struggle for peace can not succeed without fundamental changes in the corporate system that initiates, maintains, and promotes the arms race.

Early orthodontic interventions are often initiated in the developing dentition to promote favourable developmental changes. Interceptive orthodontic can eliminate or reduce the severity of a developing malocclusion, the complexity of orthodontic treatment, overall treatment time and cost. The safest way to prevent future malocclusions from tooth loss is to place a space maintainer that is effective and durable. An appropriate use of space maintainer is advocated to hold the space until the eruption of permanent teeth. This case report describes the various changing trends in use of space maintainers: conventional band and loop, prefabricated band with custom made loop and glass fibre reinforced composite resins as space maintainers.

As society transitions deeper into the Information Age, Information Technology has become a critical tool that supports all facets of the global economy. The Internet, via the World-Wide Web (WWW), has become a major component of business operations for corporate and educational organizational entities. An estimated 10,000 or more health-related websites are providing information for both consumers and healthcare professionals. In addition to private and state-supported institutions being present on the Internet, the federal government has moved rapidly toward disseminating information electronically, with significant utilization of the WWW as the technological vehicle. All branches of the US Government and federal-related agencies are now represented on the Internet in an effort to deliver content to their end users, primarily the public. The intent of this article is to complement the previous publication, "Internet Resources for Dentistry: Utilization of the Internet to Support Professional Growth, Decision Making, and Patient Care," by presenting dental healthcare professionals with information on additional governmental and medical "Internet" sites. In addition, healthcare professionals must arm themselves with more than just access itself, but also the ability to critically judge the quality of information retrieved from the WWW.

The most widely used method for controlling pain during dental procedures is the intraoral administration of local anesthetics in close proximity to a specific nerve or fiber to obtund nerve conduction. The most commonly anesthetized nerves in dentistry are branches or nerve trunks associated with the maxillary and mandibular divisions of the trigeminal nerve (cranial nerve V). However, other nerves may be inadvertently affected by intraoral local anesthesia injections, resulting in anesthetic complications of structures far from the oral cavity. Practitioners should be aware of potential ocular complications following intraoral injections in dentistry. These complications include oculomotor paralysis and vision loss. The knowledge of these conditions and their potential cause should alert the dentist to the importance of appropriate injection techniques and an understanding of management protocol.

Three different laser systems have been investigated according to their possible application in dentistry: a free running and a Q-switched microsecond Ho:YAG laser, a free running microsecond Er:YAG laser and picosecond Nd:YLF laser system consisting of an actively mode locked oscillator and a regenerative amplifier. The experiments focused on the question if lasers can support or maybe replace ordinary drilling machines. For this purpose several cavities were generated with the lasers mentioned above. Their depth and quality were judged by light and electron microscopy. The results of the experiments showed that the picosecond Nd:YLF laser system has advantages compared to other lasers regarding their application in dentistry.

Advances in biotechnology have brought gene therapy to the forefront of medical research. The concept of transferring genes to tissues for clinical applications has been discussed nearly half a century, but the ability to manipulate genetic material via recombinant DNA technology has brought this goal to reality. The feasibility of gene transfer was first demonstrated using tumour viruses. This led to development of viral and nonviral methods for the genetic modification of somatic cells. Applications of gene therapy to dental and oral problems illustrate the potential impact of this technology on dentistry. Preclinical trial results regarding the same have been very promising. In this review we will discuss methods, vectors involved, clinical implication in dentistry and scientific issues associated with gene therapy. Copyright © 2014 Elsevier Ltd. All rights reserved.

The present systematic review article is aimed at describing radiological methods utilized for human identification in forensic dentistry. For this purpose, a literature review was undertaken, and out of 45 papers, 19 were selected in accordance with inclusion criteria. Several radiological techniques can be used to assist in both individual and general identification, including determination of gender, ethnic group and, mainly, age. The analysis of ante-mortem and post-mortem radiographic and tomographic images has become an essential tool for human identification in forensic dentistry, particularly with the refinement of techniques resulting from developments in the field of the radiology itself as well as the incorporation of information technology resources to the technique. It can be concluded that, based on an appropriate knowledge on the available methods, forensic dentists can choose the best method to achieve a successful identification with a careful application of the technique and accurate interpretation of data.

The social contract is an implicit agreement between parts of society and society as a whole. Since the Middle Ages, the learned professions, recently including dentistry, have had a covenantal relationship with the public based on trust, exchanging monopoly privileges for benefiting the public good. Unlike commercial trade in commodities, professional relationships are grounded in ensuring an adequate level of oral health to all. A second contract is emerging where dentists relate to society as business operators, exchanging commodity services for a price. Recent actions by the Federal Trade Commission and the U.S. Supreme Court make it unlikely that dentistry will be able to enjoy only selected aspects of each contract while avoiding obligations that it finds unfavorable.

This paper is based on, and summarises, papers read at the second annual international conference of Nurse Education Tomorrow held at the University of Durham (UK) September 1991. To this end this paper will offer: Some Accreditation of Prior Learning (APL) definition and process as reflected in the literature available. A distinction will be made between APL and Accreditation of Prior Experiential Learning (APEL) although the procedures and processes for assessing them will be shown to be the same. A brief outline of corporate strategy, as it applies to APL, will be given to form the basis for logical demonstration of how Derbyshire Institute of Health and Community Studies has employed such a corporate strategy. Insights developed and gained from APL research currently being undertaken through the college of nursing and midwifery will be used to inform the development and nature of corporate strategy. A flowchart of the operationalisation of the corporate strategy is offered as an integrative summary of how all the APL ideas have had a positive cumulative effect. The paper finishes by highlighting the possible strengths and limitations of APL corporate strategy.

Information and communication technologies have found their application in the healthcare sector, including the frameworks of modern dentistry. CAD / CAM application in dentistry is the process by which is attained finished dental restoration through fine milling process of ready ceramic blocks. CAD / CAM is an acronym of english words Computer-Aided-Design (CAD) / Computer-Aided-Manufacture (CAM), respectively dental computer aided design and computer aided manufacture of inlays, onlays, crowns and bridges. CAD / CAM technology essentially allows you to create a two-dimensional and three-dimensional models and their materialization by numerical controlled machines. In order to operate more efficiently, reduce costs, increase user/patient satisfaction and ultimately achieve profits, many dental offices in the world have their attention focused on implementation of modern IT solutions in everyday practice. In addition to the specialized clinic management software, inventory control, etc., or hardware such as the use of lasers in cosmetic dentistry or intraoral scanning, recently the importance is given to the application of CAD / CAM technology in the field of prosthetic. After the removal of pathologically altered tooth structure, it is necessary to achieve restoration that will be most similar to the anatomy of a natural tooth. Applying CAD / CAM technology on applicable ceramic blocks it can be obtained very quick, but also very accurate restoration, in the forms of inlays, onlays, bridges and crowns. The paper presents the advantages of using this technology as well as satisfaction of the patients and dentists by using systems as: Cercon, Celay, Cerec, Lava, Everest, which represent imperative of modern dentistry in creating fixed dental restorations.

Full Text Available Local anesthetics allow a better and suitable control of pain in patients that submit to dental treatments. The pharmacology of local anesthetics is too complex, therefore it is important to know how to select the correct drug to each procedure to be accomplished. Thus, it is concluded that the production of a literary review material is of great relevance in order to gather current and important information about the local anesthetics most used in dentistry.

After decades of technical development and refinement, composite resins continue to simplify the practice of restorative dentistry, offering clinicians versatility, predictability, and enhanced physical properties. With a wide range of products available today, composite resins are a reliable, conservative, multi-functional restorative material option. As manufacturers strive to improve such properties as compression strength, flexural strength, elastic modulus, coefficient of thermal expansion, water sorption, and wear resistance, several classification systems of composite resins have been developed.

The purpose of this article is to review basic information about the alloys used for fabricating metal-ceramic restorations in dentistry. Their compositions, properties, advantages, and disadvantages are presented and compared. In addition to reviewing traditional noble-metal and base-metal metal-ceramic alloys, titanium and gold composite alloys are also discussed. A broad search of the published literature was performed using Medline to identify pertinent current articles on metal-ceramic alloys as well as articles providing a historical background about the development of these alloys. Textbooks, the internet, and manufacturers' literature were also used to supplement this information. The review discusses traditional as well as more recently-developed alloys and technologies used in dentistry for fabricating metal-ceramic restorations. Clear advantages and disadvantages for these alloy types are provided and discussed as well as the role that compositional variations have on the alloys' performance. This information should enable clinicians and technicians to easily identify the important physical properties of each type and their primary clinical indications. A number of alloys and metals are available for metal-ceramic use in dentistry. Each has its advantages and disadvantages, primarily based on its specific composition. Continuing research and development are resulting in the production of new technologies and products, giving clinicians even more choices in designing and fabricating metal-ceramic restorations.

Full Text Available During dental education, dental students learn how to examine patients, make diagnosis, plan treatment and perform dental procedures perfectly and efficiently. However, progresses in computer-based technologies including virtual reality (VR simulators, augmented reality (AR and computer aided design/computer aided manufacturing (CAD/CAM systems have resulted in new modalities for instruction and practice of dentistry. Virtual reality dental simulators enable repeated, objective and assessable practice in various controlled situations. Superimposition of three-dimensional (3D virtual images on actual images in AR allows surgeons to simultaneously visualize the surgical site and superimpose informative 3D images of invisible regions on the surgical site to serve as a guide. The use of CAD/CAM systems for designing and manufacturing of dental appliances and prostheses has been well established.This article reviews computer-based technologies, their application in dentistry and their potentials and limitations in promoting dental education, training and practice. Practitioners will be able to choose from a broader spectrum of options in their field of practice by becoming familiar with new modalities of training and practice.Keywords: Virtual Reality Exposure Therapy; Immersion; Computer-Aided Design; Dentistry; Education

Recent media reports concerning "stolen body parts" have shaken the public's trust in the safety of and the use of ethical practices involving human allografts. The authors provide a comprehensive review of the safety aspects of human bone allografts. The authors reviewed U.S. government regulations, industry standards, independent industry association guidelines, company guidelines and scientific articles related to the use of human bone allografts in the practice of dentistry published in the English language. The use of human bone allografts in the practice of dentistry involves the steps of procurement, processing, use and tracking. Rigorous donor screening and aseptic proprietary processing programs have rendered the use of human bone allografts safe and effective as a treatment option. When purchasing human bone allografts for the practice of dentistry, one should choose products accredited by the American Association of Tissue Banks for meeting uniformly high safety and quality control measures. Knowledge of human bone allograft procurement, processing, use and tracking procedures may allow dental clinicians to better educate their patients and address concerns about this valuable treatment option.
Every so often a new material, technique, or technological breakthrough spurs a paradigm shift in the way dentistry is practiced. The development and evolution of reliable enamel and dentin bonding agents is one such example. Indeed, the so-called "cosmetic revolution" in dentistry blossomed in large part due to dramatic advances in adhesive technology. It is the ability to bond various materials in a reasonably predictable fashion to both enamel and dentin substrates that enables dentists to routinely place porcelain veneers, direct and indirect composites, and a plethora of other restorative and esthetic materials. In fact, the longevity and predictability of many (if not most) current restorative procedures is wholly predicated on the dentist's ability to bond various materials to tooth tissues. Adhesive systems have progressed from the largely ineffective systems of the 1970s and early 1980s to the relatively successful total- and self-etching systems of today. The latest players in the adhesive marketplace are the so-called "universal adhesives." In theory, these systems have the potential to significantly simplify and expedite adhesive protocols and may indeed represent the next evolution in adhesive dentistry. But what defines a universal system, and are all these new systems truly "universal" and everything they are claimed to be? This article will examine the origin, chemistry, strengths, weaknesses, and clinical relevance of this new genre of dental adhesives.

Paediatric dentists receive training in sedation during their advanced education training, but evidence suggests that this training varies widely. The purpose of this study was to survey members of the International Association of Paediatric Dentistry (IAPD) and the European Academy of Paediatric Dentistry (EAPD) on their opinion on pharmacological and other behavioural management techniques and their training related to provision of oral health care of paediatric patients in the dental setting. A request was made for access to the IAPD and EAPD membership email addresses. The responses were recorded anonymously and data uploaded into spss (version 9) and analysed using descriptive analysis and chi-square with and without tabulation processes. A total of 311 respondents of 1973 targeted individuals answered the survey. The response rate was 16%. The majority of the respondents came from the continent of Europe, Asia, and the Americas. The most frequent type of sedation was general anaesthesia (52% of the respondents), followed by nitrous oxide (46%) and then oral sedation (44%). At least 91% of the respondents indicated that they were interested in the development of continuing education on the topic of sedation. Paediatric dentists around the world use relatively few behaviour management techniques, including pharmacological management. There is a definite interest in continuing education in the area of sedation. The Authors. International Journal of Paediatric Dentistry © 2011 BSPD, IAPD and Blackwell Publishing Ltd.

Full Text Available Comparative studies have demonstrated that the themes for corporate social responsibility (CSR initiatives are different among nations and geographic regions based on their cultural, political, legal, social, and economic contexts. In this research, which was conducted on 56 corporations from IMI100 (100 Iranian companies with highest annual sales, ranked by Industrial Management Institute or IMI, CSR themes in priority have been identified. Data collected from a semistructured questionnaire and some complementary interviews were analyzed against the results of a reference study over 100 companies from developed countries. The resulted themes, some of which may have several subthemes, were developed in three economic, environmental, and social categories. Beside these qualitative findings, two indices are constructed for indicating the “importance” of and “contribution” to each theme. The results and discussions are supposed to help business leaders, international companies inside Iran, governmental authorities, and researchers to improve CSR discussions and practices in the country where CSR undergoes a less structured platform.

The suitability of CTE:YAG laser radiation was investigated for caries preventive laser treatments and caries ablation. Although, CTE:YAG laser radiation at 2.69 micrometer is less highly absorbed by dental hard tissues than other erbium laser wavelengths, namely 2.79 and 2.94 micrometer, it can readily be transmitted through a conventional low hydroxyl fiber with minimal loss. These studies show that reasonable ablation rates and efficiencies are obtainable with both free running (200 microseconds) and Q-switched (100 ns) laser pulses on both dentin and enamel with the application of a relatively thick layer of water to the tissue surface. The water served to remove tissue char and debris from the ablation site leaving a clean crater. However, mechanical forces produced during the energetic ablative process resulted in peripheral mechanical damage to the tissue. Surface dissolution studies on enamel indicated that CTE:YAG radiation inhibited surface dissolution by organic acid by 60 - 70% compared to unirradiated controls, albeit, at fluences an order of magnitude higher than those required for CO2 laser radiation. This layer system may be suitable for dental hard tissue applications if mechanical damage can be mitigated. This work was supported by NIH/NIDR Grants R29DE12091 and R01DE09958.

In the face of extraordinary advances in the prevention, diagnosis, and treatment of human diseases, the inability of most tissues and organs to repair and regenerate after damage is a problem that needs to be solved. Stem cell research is being pursued in the hope of achieving major medical breakthroughs. Scientists are striving to create therapies that rebuild or replace damaged cells with tissues grown from stem cells that will offer hope to people suffering from various ailments. Regeneration of damaged periodontal tissue, bone, pulp, and dentin is a problem that dentists face today. Stem cells present in dental pulp, periodontal ligament, and alveolar bone marrow have the potential to repair and regenerate teeth and periodontal structures. These stem cells can be harvested from dental pulp, periodontal ligament, and/or alveolar bone marrow; expanded; embedded in an appropriate scaffold; and transplanted back into a defect to regenerate bone and tooth structures. These cells have the potential to regenerate dentin, periodontal ligament, and cementum and can also be used to restore bone defects. The kind of scaffold, the source of cells, the type of in vitro culturing, and the type of surgical procedure to be used all require careful consideration. The endeavor is clearly multidisciplinary in nature, and the practicing dental surgeon has a critical role in it. Playing this role in the most effective way requires awareness of the huge potential associated with the use of stem cells in a clinical setting, as well as a proper understanding of the related problems.

Indian women, have come up a long way during the past 50 years. Gone are the days when the leadership positions in dentistry and health care professions were occupied solely by males and the women in-charge were looked down upon as anomalies. The staff rooms in dental and medical schools, the research laboratories in India today are employing women, who have quietly begun challenging the conventional male ideas that had shaped the policies earlier on. Women have advanced considerably in academic dentistry but like every coin, this story too, has two sides. In spite of the considerable gain in equity of status, women in research and academic careers related to health care professions still face innumerable barriers to their careers. This study was conducted with an aim to highlight the various barriers being faced by women in leadership positions in academic dentistry in India and this paper also suggests issues which require global concern for unbiased advancement of women. This was a questionnaire-based study in which the subjects were women in leadership positions in the various dental colleges in India. The questions are related to the various barriers like family commitments, attitude of the society, sexual harassment, gender bias and lack of cooperation from spouse which hinders the development of the careers of such women with tremendous potential. The results show that 67% of the subjects feel there are more barriers to their careers as women than men and health care professions definitely need more women leaders for improvement in women's health status globally. 63.5% of women in dentistry feel their family commitments are barriers to rising in their careers and 64.7% report that a marriage is happier if the husband's career graph is better than wife's. The survey results indicate that the same salary is paid to 93.5% women as their male colleagues. The results of the study show that there certainly has been a change in outlook of Indian women as they have

Full Text Available Humans have had a tremendous impact on the ecology and of late have rapidly damaged its delicate balance. Dentists as protectors of oral health should not limit their responsibilities to patient treatment but also inculcate methods to protect the environment as well. Thus the concept of eco-friendly dentistry or green dentistry has been introduced. Eco-dentistry or "green dentistry" is a practice of dentistry using technologies and materials that promote and protect the planet. It is a thought process, an attitude, and a guide for making earth friendly choices in dental practice. This article intends to provide guidance to practitioners about the practical changes we can make in practice, so as to minimizing the release of potential pollutants and reduce the impact of dentistry on Earth.

Full Text Available Integrating corporate governance into brand management is fundamental for protecting shareholders, considering the increasing importance of brands in firms’ performance and the dissociation between shareholders and managers in most large and medium firms. This paper designs a corporate governance system model on a brand level, which takes into account preventive, simultaneous and retroactive governance. Moreover, we highlight the importance of transition management when changes to brand management come into question. Finally, we propose six corporate governance instruments for brand management: performance indicators, the brand marketing plan, periodic reports, the brand council, brand audit, and transition management.

This research examines 126 manufacturing companies which are listed in Indonesian Stock Exchange (ISX and have issued an audited financial statement for 2006. The statistical method used to test the hypothesis is Path Analysis. The result suggests that Good Corporate Governance influences both the disclosure of Corporate Social Responsibility and Corporate Financial Performance and that Corporate Social Responsibility significantly influences Corporate Financial Performance. The result also suggests that CEO Tenure, the controlling variable, holds a significant influence on the disclosure of Corporate Social Responsibility. Yet, there is no strong evidence to support the type of industries as an influencing factor of Corporate Social Responsibility.

The aim of this study was to determine whether changes in student selection criteria at The University of Adelaide effected a change in motivation and influencing factors to study dentistry by comparing cohorts. Online questionnaire completed by first-year dentistry students at The University of Adelaide between 1993-1996 and 1997-2005. All 666 students completed the questionnaire with 647 suitable for analysis. The likelihood of students being motivated for a career in dentistry because it 'fits with family' was greater for the 1997-2005 cohort (OR = 1.68, 95% CI = 1.14-2.49, p dentistry. © 2014 Australian Dental Association.

History has revealed that there is a never-ending evolution of theories or models of corporate governance. Companies are trying to instill the sense of governance into their corporate structure. This article is a review of literature on the range of theories in corporate governance. The fundamental theories in corporate governance began with the agency theory, expanded into stewardship theory and stakeholder theory and evolved to transaction cost theory. However, these theories address the ca...

For children to receive needed oral health care, adequate training at both the predoctoral and postdoctoral levels of dental education is required, but previous studies have found inadequacies in predoctoral education that lead to general dentists' unwillingness to treat certain young populations. As another way of assessing predoctoral preparation, the aim of this study was to determine the perspectives of first-year residents and pediatric program directors about residents' preparedness to enter advanced education programs in pediatric dentistry. Surveys were sent to all 74 U.S. program directors and 360 first-year residents. The survey focused on procedures related to prevention, behavior management, restorative procedures, pulp therapy, sedation, and surgery, as well as treating patients funded by Medicaid and with special health care needs. Among the first-year residents, 173 surveys were returned for a 48% response rate; 61 directors returned surveys for an 82% response rate. Only half of the residents (55%) reported feeling adequately prepared for their first year in residency; less than half cited adequate preparation to place stainless steel crowns (SSCs) (42%) and perform pulpotomies (45%). Far fewer felt adequately prepared to provide treatment for children six months to three years of age, including examinations (29%), infant oral exams (27%), and children with severe caries (37%). The program directors were even less positive about the adequacy of residents' preparation. Only 17% deemed them adequately prepared to place SSCs and 13% to perform pulpotomies. Approximately half reported their first-year residents were inadequately prepared to treat very young children and children with severe caries (55% each). This study found that the perceived inadequacy of predoctoral education in pediatric dentistry was consistent at both the learner and educator levels, supporting previous studies identifying inadequacies in this area.

Research has clearly demonstrated associations between corporal punishment of children and maladaptive behavior patterns such as aggression and delinquency. Hitting children is an act of violence and a clear violation of children's human rights. In this article, the position of the United States on corporal punishment of children is discussed. Professional and international progress on ending corporal punishment is explained, and the relationship between corporal punishment and child abuse is discussed. An appeal is made for prevention efforts such as parent education and removal of social sanctions for hitting children that may hold significant promise for preventing child maltreatment.

Quality assurance involves the cycle of quality assessment, formal identification of problems, developing a strategy for resolving problems and implementation of changes. Historically, the term "first do not harm" can be considered as the first step in quality assurance. Patients' high expectations from the outcomes of dental treatment, new technology and cost containment changed the perspectives completely. We are facing a new era of an increasing demand for patients' involvement as well as an increasing demand for accountability of the members of the profession. The article describes the development of the issue of quality assurance during the last thirty years and highlights the difficulties encountered by the profession in adjusting the changes due to lack of education, experience, knowledge and absence of a definition for accepted criteria for action. Developing criteria for appropriateness of dental treatment, developing mechanisms for assessing the art of care, development of large data bases and development of consumers' surveys are some of the leading suggestions for future action. The responsibility for quality and quality assurance lies in the hands of the dental profession. Organized dentistry possesses a social and ethical commitment for the society, as well as professional obligation for the members of the profession. Although cost containment gave rise to the issue of quality, quality assurance should not be measured in financial terms, but in terms of accepting responsibility and working for continuous improvement. Steps in the right direction will, hopefully, lead to a better and more efficient utilization of the available resources and will increase the trust of the public in the profession of dentistry. Therefore, organized dentistry should not leave this important issue to be dealt by non-dental professions or commercial organizations.

Full Text Available The essence of dental education is not only to impart knowledge but also to equip an aspiring clinician with all the para-phernalia to face most clinical situations if not all. What be-comes important here is the requirement that a student be not only observant but also have a precise idea of what a lesion or a surface should feel like under an instrument. No matter how far we have come in terms of pathogenesis and treatment of diseases of the oral cavity, there is still no one good way to teach a student about the tactile sense, be it while de-tecting calculus/caries or placing the incisions or detecting the smoothness of a restoration. Most often than not students learn these by a trial and error method. A not-so-recent development called Haptics may well be the answer to this predicament, at least in the near future. The concept which is extensively in use and indis-pensable in other fields like aviation, telecommunication etc is now making inroads into dentistry. It is essentially software which brings in the idea of giving the feedback response to applied force, be it simple exploration of caries or the fine pressure applied in placing an incision or an array of other areas/situations in dentistry where fine tactile sense becomes a prerequisite for intelligent diagnoses or cutting edge treatment procedures. The following write-up is an attempt to throw light on this new technology and the impact it may have on pre-clinical teaching in dentistry. The advantages, disadvantages be-tween manikin based dental simulators and haptics based dental simulators are also pre-sented.

The aim of this study was to assess the scientific output of Spanish universities that offer a bachelor's degree in dentistry through the use of various bibliometric indicators. A total of 21 universities offered a bachelor's degree in dentistry in academic year 2016-2017. The search for papers published by authors associated with these institutions was carried out using the selection of journals listed in the Journal Citation Reports (JCR) and the Web of Knowledge database for the period 1986-2017. On the basis of these data, we determined the output, the h-, g- and hg-indexes, the most productive authors, international collaborations, and the most relevant journals. Public universities obtained better results than private universities. The University of Valencia was ranked first, followed by the Complutense University of Madrid and the University of Granada. The most productive author was José Vicente Bagán, but the author with the highest h-index was Mariano Sanz and Manuel Toledado. The universities with the greatest output and highest citation rates had more international collaborations. The most developed fields in Spanish universities were Oral surgery, Oral medicine and Dental materials. The universities had different models of production. At universities such as Barcelona or Valencia, the production was focused on very few departments and authors. At the other extreme, the University of Granada had various sources of research and authors, which meant that its output and citation rate could increase more. University faculties must provide suitable academic and research training, and therefore must be assessed using objective criteria and bibliometric tools. Although the number of university schools and faculties that teach dentistry has increased, and particularly the number of private universities, there is no correlation between their quality and output and the number of places offered on their courses.
Full Text Available Background: The role of scientific journals in diffusion of data concerning research in the field of Public Health Dentistry is of premier importance. Bibliometry involves analysis of publications reflecting the type of research work. Objective: To determine the number and trends of published articles in Journal of Indian association of Public Health Dentistry (JIAPHD and to compare the same with that of Community Dentistry and Oral Epidemiology (CDOE from year 2002 to 2013. Methodology: A retrospective observational study was conducted for JIAPHD and CDOE. All issues of JIAPHD and CDOE from 2002 to 2013 were hand searched for the parameters: Study design, area of interest of research, state/college where research was conducted, authorship pattern, source of articles published each year, changing study trends, disease under study and publication bias. The data were organized and analyzed using software SPSS - version 21.0; descriptive and inferential statistical test (Chi-square test was used to find a significant difference between the two journals. Results: A total of 676 and 744 articles was retrieved from JIAPHD and CDOE respectively. An increase in a number of articles from 2002 to 2013 was observed in JIAPHD. About 78.8% of articles in CDOE and 68.6% in JIAPHD were observational studies (P = 0. 001 and 60% of CDOE articles and 45.3% of JIAPHD articles had > 3 authors from educational institutes (P = 0. 001. Conclusion: The bibliometric analysis of JIAPHD in comparison to CDOE showed an interesting pattern. It was reasoned that most articles published were of descriptive and analytical epidemiology indicating a demand for leading dental research based on better quality methodology in terms of research and systematic inspections. Also, JIAPHD needs to be more coherent as far as publication issues are concerned.

Ketamine has been used as a safe and effective sedative to treat adults and children exhibiting high levels of anxiety or fear during dental treatment. Pediatric dentistry often involves patients with high levels of anxiety and fear and possibly few positive dental experiences. Patient management can involve behavioral approaches, as well as the use of sedation or general anesthesia with a variety of agents, including midazolam, diazepam, hydroxyzine, meperidine, and ketamine. The aim of this study was to investigate the clinical efficacy of ketamine use in pediatric sedation dentistry through systematic review and analysis. A systematic review of publications between 1990 and 2015 was conducted using PubMed and MEDLINE databases maintained by the US National Library of Medicine and the National Institutes of Health. The keywords used were (ketamine) AND (dental OR dentistry) AND (sedation). The abstract and title of all potential publications were then screened for clinical trials and to remove non-English articles, non-human or animal trials, and other non-dental or non-relevant studies. A total of 1,657 citations were initially identified, reviewed, and screened, eventually resulting in inclusion of 25 clinical trials in this systematic review. Nineteen studies evaluated ketamine effects in pediatric dental sedation using oral (non-invasive) administration, three involved subcutaneous or intramuscular injection, and three were completed intravenously. Evidence analysis of these trials revealed the majority (n = 22/25) provided strong, positive evidence for the use of ketamine (alone or in combination) to reduce dental anxiety and behavioral non-compliance with the remainder suggesting equivocal results. Additional endpoints evaluated in some studies involved dosage, as well as time to achieve sedation effect. The use of ketamine (alone or in combination) can provide safe, effective, and timely sedation in pediatric patients regardless of the route of

Intraoral scan body (ISB) design is highly variable and its role in the digital workflow and accuracy of digital impressions is not well understood. The purpose of this systematic review was to determine the relevant reports pertaining to ISBs with regard to design and accuracy and to describe their evolution and role in the digital dentistry workflow. Special attention was placed on their key features in relation to intraoral scanning technology and the digitization process. A MEDLINE/PubMed search was performed to identify relevant reports pertaining to ISB usage in dentistry. This search included but was not limited to scan body features and design, scan body accuracy, and scan body techniques and the role of ISBs in computer-aided design and computer-aided manufacturing (CAD-CAM) processes. Commercially available scan bodies were examined, and a patient situation was shown highlighting the use of ISBs in the digital workflow. Deficiencies in the reports were found regarding various scan body topics, including ISB features/design, accuracy, and the role of ISBs in CAD-CAM processes. ISBs are complex implant-positioning-transfer devices that play an essential role in the digital workflow and fabrication of accurately fitting implant-supported restorations. With scanner technology rapidly evolving and becoming more widespread, future studies are needed and should be directed toward all parts of the digital workflow when using ISBs. By understanding the basic components of ISBs and how they relate to digital scanning and CAD-CAM technology, more emphasis may be placed on their importance and usage in the digital workflow to ensure accurate transfer of implant position to the virtual and analog definitive cast. Efforts should be made by clinicians to identify an optimal ISB design in relation to the specific intraoral scanning technology being used.

Witness seminars attempt to get behind the scenes of advances and developments to find out what really happened at certain times; they are not intended to provide a detailed history of events. This paper presents highlights from the five John McLean Archive witness seminars, providing an instructional collection of memories and insights into the world of dentistry in the UK since the late 1940s. It is concluded that future change will be seen as a welcome constant to be used for the benefit of the profession and the patients and communities it serves.

Diabetes mellitus is a syndrome of abnormal carbohydrate, fat and protein metabolism that results in acute and chronic complications due to the absolute or relative lack of insulin. Globally, it is expected that the number of people with diabetes will increase, and as a result dental practitioners will encounter an increasing number of patients affected by this chronic condition, which may have implications for the provision of safe and appropriate dental treatment. This article aims to provide an overview of diabetes and to discuss aspects of the condition relevant to dentistry. The article also discusses the management of diabetic emergencies in a dental practice setting.

Stereopsis and its role in dental practice has been a topic of debate in recent editions of this Journal. These discussions are particularly timely as they come at a point when virtual reality simulators are becoming increasingly popular in the education of tomorrow's dentists. The aim of this article is to discuss the lack of robust empirical evidence to ascertain the relationship (if any) between stereopsis and dentistry and to build a case for the need for further research to build a strong evidence base on the topic.
Full Text Available Material is a crucial factor for the restoration of the tooth or periodontal structure in dentistry. Various biomaterials have been developed and clinically applied for improved periodontal tissue regeneration and osseointegration, especially in periodontology and dental implantology. Furthermore, the biomimetic approach has been the subject of active research in recent years. In this review, the most widely studied biomaterials (bone graft material, barrier membrane, and growth or differentiation factors and biomimetic approaches to obtain optimal tissue regeneration by making the environment almost similar to that of the extracellular matrix are discussed and specifically highlighted.

Full Text Available The issue of corporate governance has become increasingly important as globalisation has begun to accelerate and the economic and financial turmoil have intensified. Post-crisis context has imposed the need to expand the prospects for analysis over governance and companies, as well as the need to identify new ways of administration and resource management. From this perspective, the author aims to highlight the conditions, factors and events that have generated profound changes within the business environment, while the analysis is focusing on contemporary changes in the systems of corporate governance and economic mutations, especially in terms of the companies. The establishment of new governance rules is demanding a theoretical approach based on new methodological requirements which are needed to reform theoretical foundations and to promote creative and effective shapes and governance systems.
Full Text Available Culture is one of those terms that are difficult to express distinctly, but everyone knows it when they sense it. Many articles have been written in recent years about corporate culture, which can be looked at as a system. Inputs include feedback from society, professions, laws, stories, heroes, values on competition or service, etc. Outputs are organizational behaviors, technologies, strategies, image, products, services, appearance, etc. Most organizations don't consciously try to create a certain culture, as it is typically created unconsciously, based on the values of the top management or the founders of an organization. In this paper we try to see whether corporate culture has any influence on competition and if it has, whether it is a positive one or a negative one.

We examine the strategic use of Corporate Social Responsibility (CSR) in imperfectly competitive markets. The level of CSR determines the weight a firm puts on consumer surplus in its objective function before it decides upon supply. First, we consider symmetric Cournot competition and show that the endogenous level of CSR is positive for any given number of firms. However, positive CSR levels imply smaller equilibrium profits. Second, we find that an incumbent monopolist can use CSR as an en...

The purpose of this study was to identify the status of pre-doctoral geriatric dentistry education among all Chilean dental schools. Chile is one of the most rapidly ageing countries in Latin America. Consequently, specific knowledge and training on the needs of elderly populations need to be emphasised in dental schools. The current extent and methods of teaching geriatric dentistry among the dental schools in Chile are unknown. A web-based questionnaire was developed and sent to all 19 Chilean dental schools to identify which schools had a formal programme on geriatric dentistry and ask about their format, content and type of training of the faculty who taught in the programmes. Data were analysed, and a comparison was made among the schools. Sixteen (84%) of the participant schools reported teaching at least some aspects of geriatric dentistry, using various methodologies, but only 7 (37%) had specific courses. Of those schools reporting a didactic content on geriatric dentistry, 71% included clinical training, either in the school's dental clinics or in an extramural service. Contents mostly included demographics of ageing, theories of ageing and medical conditions. More than half of the faculty (57%) stated that they had formal training in geriatric dentistry, 43% were trained in prosthodontics, public health or other areas. Although most dental schools taught geriatric dentistry, only some had a specific course. Most schools with formal courses followed the international curriculum guidelines for geriatric dentistry. © 2014 John Wiley & Sons A/S and The Gerodontology Association.

Objective To assess new UK graduates' knowledge of training and service provision within restorative dentistry.Design A national descriptive cross-sectional survey.Subjects and methods An online survey assessing clinicians' knowledge of restorative dentistry, who had graduated within the last four years in the UK, was distributed across the UK via postgraduate dental deaneries. One-hundred responses were accepted as a sample of a potential population of 4,000.Main outcome measure How well respondents understood the service provision and training aspects of the specialty of restorative dentistry.Results The responses were received from graduates from a variety of dental schools across the UK. Of those respondents, 41 reported receiving career guidance within restorative dentistry. 45 new graduates were confident in their understanding of the specialty, while 53 were confident in the differences between restorative dentistry and monospecialty training. The respondents appeared unaware regarding treatment priorities within restorative dentistry departments. Most respondents felt that receiving teaching on restorative dentistry as a specialty and career pathway would be beneficial.Conclusion The results suggest that new graduates may benefit from clarification regarding the specialty of restorative dentistry, however, caution must be taken due to the limitations of the study.

To summarize and discuss how geriatric dentistry has been addressed in dental schools of different countries regarding to (1) teaching students at the predoctoral level; (2) advanced training, and (3) research. A convenience sample of faculty members from a selection of high, upper-middle and lower-middle income countries were recruited to complete the survey. The survey had 5 open-ended main topics, and asked about (1) the size of their elderly population, (2) general information about dental education; (3) the number of dental schools teaching geriatric dentistry, and their teaching methods; (4) advanced training in geriatric dentistry; (5) scholarship/research in geriatric dentistry. (1) There is great variation in the size of elderly population; (2) duration of training and content of dental education curriculum varies; (3) geriatric dentistry has not been established as a standalone course in dental schools in the majority of the countries, (4) most countries, with the exception of Japan, lack adequate number of dentists trained in geriatric dentistry as well as training programs, and (5) geriatric dentistry-related research has increased in recent years in scope and content, although the majority of these papers are not in English. © 2018 Special Care Dentistry Association and Wiley Periodicals, Inc.

This publication describes the history of Minimal Intervention Dentistry (MID) for managing dental caries and presents evidence for various carious lesion detection devices, for preventive measures, for restorative and non-restorative therapies as well as for repairing rather than replacing defective restorations. It is a follow-up to the FDI World Dental Federation publication on MID, of 2000. The dental profession currently is faced with an enormous task of how to manage the high burden of consequences of the caries process amongst the world population. If it is to manage carious lesion development and its progression, it should move away from the ‘surgical’ care approach and fully embrace the MID approach. The chance for MID to be successful is thought to be increased tremendously if dental caries is not considered an infectious but instead a behavioural disease with a bacterial component. Controlling the two main carious lesion development related behaviours, i.e. intake and frequency of fermentable sugars, to not more than five times daily and removing/disturbing dental plaque from all tooth surfaces using an effective fluoridated toothpaste twice daily, are the ingredients for reducing the burden of dental caries in many communities in the world. FDI’s policy of reducing the need for restorative therapy by placing an even greater emphasis on caries prevention than is currently done, is therefore, worth pursuing. PMID:23106836

Silicates and silicate-based compounds are frequently used materials in dentistry. One of their major applications is their use as fillers in different dental filling materials such as glass-ionomer cements, compomers, composites, and adhesive systems. In these materials, the fillers react with acids during the setting process or they improve the mechanical properties by increasing physical resistance, thermal expansion coefficient and radiopacity in acrylic filling materials. They also reduce polymerization shrinkage, and increase esthetics as well as handling properties. Furthermore, silicates are used for the tribochemical silication of different surfaces such as ceramics or alloys. The silicate layer formed in this process is the chemical basis for silanes that form a bond between this layer and the organic composite matrix. It also provides a micromechanical bond between the surface of the material and the composite matrix. Silicates are also a component of dental ceramics, which are frequently used in dentistry, for instance for veneers, inlays, and onlays, for denture teeth, and for full-ceramic crowns or as crown veneering materials.

Digital photographs play a substantial role in the presentation and validation of clinical cases for documentation and research purposes in esthetically oriented professions such as dentistry. The introduction of sophisticated cameras and "easy to use" computer software readily available on today's market has enabled digital fraud to emerge as a common and widely used practice. Hence, it is essential that both dentists and editorial circles are aware and cautious with regard to the possibility of digital fraud. A set of 10 routine "pre-" and "post" treatment dental procedure photographs were taken and randomly manipulated using standard desktop software. A team of 10 dental professionals were selected and each one of them was individually requested to review and evaluate the authenticity of the photographs. An assessment of expert opinion revealed an overall sensitivity of 60% and a sensitivity of 15% in correctly identifying a manipulated photograph, which is considered low. Furthermore, there was poor interobserver agreement. Advanced technology that is easily available has resulted in adept digital fraud that is difficult to detect. There is a need for awareness among both dental practitioners and the editorial circle regarding misrepresentation due to image manipulation. It is therefore necessary to follow a skeptical approach in the assessment of digitalized photos used in research and as a part of clinical dentistry.

Additive manufacturing (AM) or 3D printing has been hailed as the third industrial revolution as it has caused a paradigm shift in the way objects have been manufactured. Conventionally, converting a raw material to a fully finished and assembled, usable product comprises several steps which can be eliminated by using this process as functional products can be created directly from the raw material at a fraction of the time originally consumed. Thus, AM has found applications in several sectors including automotive, aerospace, printed electronics, and healthcare. AM is increasingly being used in the healthcare sector, given its potential to fabricate patient-specific customized implants with required accuracy and precision. Implantable heart valves, rib cages, and bones are some of the examples where AM technologies are used. A vast variety of materials including ceramics, metals, polymers, and composites have been processed to fabricate intricate implants using 3D printing. The applications of AM in dentistry include maxillofacial implants, dentures, and other prosthetic aids. It may also be used in surgical training and planning, as anatomical models can be created at ease using AM. This article gives an overview of the AM process and reviews in detail the applications of 3D printing in dentistry. © 2017 Wiley Periodicals, Inc.

Use of guidelines is an important means of reducing the gap between research and clinical practice. Sound and unbiased information should be available to enable dental professionals to provide better clinical treatment for their patients. The development of clinical guidelines in dentistry should follow standard and transparent methodology. The purpose of this article is to propose important steps for developing evidence-based clinical recommendations in dentistry. Initially, dental guidelines should be extensively sought and assessed to answer focused clinical questions. If there is a paucity of guidelines or if existing guidelines are not of good methodological quality, systematic reviews should be searched or conducted to serve as a basis for the development of evidence-based guidelines. When systematic reviews are produced, they should be rigorous in order to provide the best evidence possible. In the last phase of the process, the overall quality of evidence should be scrutinized and assessed, together with other factors (balance between treatment effects and side effects, patients' values, and cost-effectiveness of therapy) to determine the strength of recommendations. It is expected this approach will result in the development of sound clinical guidelines and consequent improvement of dental treatment.

To assess referrals to sedation, examining dental anxiety and background of patients, and compare these characteristics to those referred to a restorative dentistry clinic. Descriptive, cross sectional survey. Subjects were 100 consecutive new patients in sedation and special care and 50 new patients in restorative dentistry at Guy's and St Thomas NHS Foundation Trust. A questionnaire included demographics, self-reported oral health and dental attendance, and dental fear. Information from the patients records was taken: ASA classification, previous sedation or general anaesthesia, alcohol and tobacco use, and medications. The best predictors of referral were dental anxiety level and an irregular attendance. The most important fears were seeing, hearing and feeling the vibrations of the dental drill, and the perception of an accelerated heart rate. Other factors such as general, mental and dental health and alcohol use were related to referral but less important. Referral is consistent with the goal of the sedation clinic to see anxious patients. Referring general practitioners are able to identify these patients.

Additive manufacturing or 3D printing is becoming an alternative to subtractive manufacturing or milling in the area of computer-aided manufacturing. Research on material for use in additive manufacturing is ongoing, and a wide variety of materials are being used or developed for use in dentistry. Some materials, however, such as cobalt chromium, still lack sufficient research to allow definite conclusions about the suitability of their use in clinical dental practice. Despite this, due to the wide variety of machines that use additive manufacturing, there is much more flexibility in the build material and geometry when building structures compared with subtractive manufacturing. Overall additive manufacturing produces little material waste and is energy efficient when compared to subtractive manufacturing, due to passivity and the additive layering nature of the build process. Such features make the technique suitable to be used with fabricating structures out of hard to handle materials such as cobalt chromium. The main limitations of this technology include the appearance of steps due to layering of material and difficulty in fabricating certain material generally used in dentistry for use in 3D printing such as ceramics. The current pace of technological development, however, promises exciting possibilities. © 2016 by the American College of Prosthodontists.

Evidence-based practice requires clinical trials to be performed. In India, if any clinical trial has to be performed, it has to be registered with clinical trial registry of India. Studies have shown that the report of clinical trials is poor in dentistry. Hence, the present study has been conducted to assess the type and trends of clinical trials being undertaken in dentistry in India over a span of 6 years. All the clinical trials which were registered with the Central Trial Registry of India (CTRI) (www.ctri.nic.in) from January 1, 2007 to March 3, 2014 were evaluated using the keyword "dental." Following information were collected for each of the clinical trials obtained from the search; number of centres (single center/multicentric), type of the institution undertaking the research (government/private/combined), study (observational/interventional), study design (randomized/single blinded/double-blinded), type of health condition, type of participants (healthy/patients), sponsors (academia/commercial), phase of clinical trial (Phase 1/2/3/4), publication details (published/not published), whether it was a postgraduate thesis or not and prospective or retrospective registration of clinical trials, methodological quality (method of randomization, allocation concealment). Descriptive statistics was used for analysis of various categories. Trend analysis was done to assess the changes over a period of time. The search yielded a total of 84 trials of which majority of them were single centered. Considering the study design more than half of the registered clinical trials were double-blinded (47/84 [56%]). With regard to the place of conducting a trial, most of the trials were planned to be performed in private hospitals (56/84 [66.7%]). Most (79/84, 94.1%) of the clinical trials were interventional while only 5/84 (5.9%) were observational. Majority (65/84, 77.4%) of the registered clinical trials were recruiting patients while the rest were being done in healthy

Many corporate organizations around the world are looking at new ways to improve the health and well-being of their employees. Many have begun to use m-health approaches and unique applications (apps) to provide assistance. In Germany, both m-health and occupational health management (OHM) are growing quickly. Therefore, we hypothesized that the combination-apps usage in OHM-is growing as well. We studied the usage of health apps in large corporations for health management of employed individuals. To understand the environment in Germany, a two-part study was conducted. First, an extensive literature search was done and second, interviews were conducted with 12 of the 20 biggest companies' health management representatives. Using key search terms, 5,445 peer-reviewed journal articles traced with German databases and on PubMed were reviewed. Interestingly and somewhat surprising to the authors, none of them covered our specific topic. Interviews were conducted with 60% of the companies indicated. Only 3 out of 12 companies use apps. Four companies are piloting apps. With one exception, apps cover well-known areas such as food coaching, physical motion, smoking cessation, stress prevention, and other health-related subjects. One app used sensors in work clothing to prevent unhealthy motion. With a few exceptions, there has been no evaluation of the utility and utilization of apps. Current app usage in corporate health management in Germany is surprisingly low. Apps need to be better evaluated. Main obstacles-which could be resolved in the future-are legal restrictions (especially on data security), the lack of company-owned smart phones, misfit of apps and corporate health strategy, a lack of app evaluation, and high app prices.

Background Students’ motives for studying Dentistry have been a subject of interest for years because of the potential for understanding the psychological makeup and subsequent job satisfaction for the dentist. It is also useful in identifying expectations of the profession. This study therefore tried to identify study motives and career preferences of dental students especially with respect to the practice of paediatric dentistry. Methods This was a cross-sectional study using a self-administered questionnaire. The final year students in six dental schools in Nigeria were required to fill the questionnaire. Students were asked to rank their motives and career preferences on a Likert like scale with points ranging from 0–5 where 0 represented a factor that had no influence on their decision and 5 represented a very influential factor. The underlying dimensions for study motives, career preference, impression about and motive for interest in the practice of paediatric dentistry were identified using factor analysis. Results One hundred and seventy nine of 223 students (80.3%) participated in this study. Motives for the practice of dentistry included characteristics of the profession, altruism and intellectual challenges, existence of artistic theme in dentistry and parent’s recommendation. Overall, 67.1% of respondents indicated interest in postgraduate studies and 50.8% were interested in paediatric dentistry practice. The main motives for showing interest in the practice of paediatric dentistry were ‘personal interest, professional interest and interest of significant others in children’, and ‘family influence’. Significantly more males than females were interested in the practice of paediatric dentistry though the motives for interest in the practice of paediatric dentistry did not differ significantly by sex or age. Conclusion The non-significant sex difference in the motives for interest in the practice of paediatric dentistry is a possible

Geriatric dentistry and its instruction are critical in a rapidly aging population. Japan is the world’s fastest-aging society, and thus geriatric dentistry education in Japan can serve as a global model for other countries that will soon encounter the issues that Japan has already confronted. This study aimed to evaluate geriatric dental education with respect to the overall dental education system, undergraduate geriatric dentistry curricula, mandatory internships, and graduate geriatric education of a selected dental school in Japan. Bibliographic data and local information were collected. Descriptive and statistical analyses (Fisher and Chi-square test) were conducted. Japanese dental schools teach geriatric dentistry in 10 geriatric dentistry departments as well as in prosthodontic departments. There was no significant differences found between the number of public and private dental schools with geriatric dentistry departments (p = 0.615). At Showa University School of Dentistry, there are more didactic hours than practical training hours; however, there is no significant didactic/practical hour distribution difference between the overall dental curriculum and fourth-year dental students’ geriatric dental education curriculum (p=0.077). Graduate geriatric education is unique because it is a four-year Ph.D. course of study; there is neither a Master’s degree program nor a certificate program in Geriatric Dentistry. Overall, both undergraduate and graduate geriatric dentistry curricula are multidisciplinary. This study contributes to a better understanding of geriatric dental education in Japan; the implications of this study include developing a clinical/didactic curriculum, designing new national/international dental public health policies, and calibrating the competency of dentists in geriatric dentistry.
