Diferentes cepillos dentales se han desarrollado para facilitar la mantención de una adecuada higiene oral en estos pacientes, sin embargo, se ha observado que los cepillos comunmente indicados (cepillo ortodóncico mas cepillo unipenacho, no siempre son bien manejados y difícilmente se usan ambos. El cepillo Cross Action Pro-Salud®, se ha presentado como una alternativa simple de usar y de transportar, por ser un único cepillo que combina las caracteristicas de los dos cepillos comunmente recomendados. Para evaluar la efectividad de este cepillo, en comparación con la prescripción convencional, se evaluaron 2 grupos, de 23 pacientes cada uno, portadores de aparatología fija. Un grupo utilizó la prescripción habitual y un segundo grupo utilizó cepillo Cross Action Pro-Salud®, por un período de 45 días. Los indices de higiene de O`leary, de placa en brackets y gingival modificado fueron registrados al inicio y 45 días después del uso diario de los cepillos antes mencionados. Se utilizó test-t para comparar los resultados obtenidos y se determinó que se produjo una disminución significativa en los tres indices de higiene, no existiendo diferencias en los resultados obtenidos entre ambas prescripciones. El cepillo Oral-B Cross-Action Pro-Salud® es una alternativa recomendable, ya que permite eliminar efectivamente la placa bacteriana en pacientes ortodónticos, y al ser un único cepillo, facilita y acorta el tiempo de cepillado.Orthodontic fixed appliances include elements that allow the accumulation of bacterial plaque, making tooth brushing more difficult and increasing the risk of developing caries, white spot lesions, and periodontal disease.

    Full Text Available Head louse infestation, or pediculosis capitis, caused by Pediculus humanus var. capitis, is a common health concern in pediatric age group. An itching of the scalp is the chief symptom, whereas presence of viable nits confirms the diagnosis of head louse infestation. Secondary bacterial infection with impetignization with cervical and occipital lymphadenopathy can complicate the clinical scenario with physician misdiagnosing pediculosis to a primary bacterial infection. Screening and treatment of all close contacts is necessary for an adequate management of pediculosis. Medical management of head louse infestation requires proper application of topical pediculicidal agents′, chiefly permethrin lotion and wet combing with a fine toothcomb. Severe cases with high parasitic load justify the use of either oral cotrimoxazole or Ivermectin. Other described technique involves a single application of hot air for 30 minutes. Radical but culturally unacceptable method would be shaving of scalp in resistant cases. Environmental fogging with insecticides is neither necessary nor recommended.

    2011-10-01

    Spinosad 0.9% suspension is a topical treatment for head-lice infestation (pediculosis capitis) that has been approved in the US as a prescription medicine. Spinosad is a natural mixture of the pediculicidal tetracyclic macrolides spinosyn A and spinosyn D. Spinosad 0.9% mainly interferes with nicotinic acetylcholine receptors in insects, thereby producing neuronal excitation that results in paralysis of lice from neuromuscular fatigue after extended periods of hyperexcitation. Spinosad 0.9% kills both permethrin-susceptible and permethrin-resistant populations of lice. It is also ovicidal, killing both eggs (nits) and lice. Systemic absorption was not detectable after a single topical application of spinosad 1.8% for 10 minutes in children. In randomized, evaluator-blind, multicenter clinical trials, topical spinosad 0.9% without nit combing was significantly more effective than permethrin 1% with nit combing in the eradication of head lice assessed 14 days after one or two treatments. The majority of subjects treated with spinosad 0.9% without nit combing required only a single treatment to eradicate head lice, while the majority of those treated with permethrin 1% with nit combing required two treatments. Spinosad was generally well tolerated in clinical trials, with no severe or serious adverse events. Cutaneous and ocular irritation were the most common adverse events. PMID:21834600

    A review of the current evidence on primary treatment modalities of head lice demonstrates increasing resistance to current regimens. New and alternative therapies are now available. A treatment algorithm was created to address safety and efficacy of treatments, as well as to guide clinicians through navigation of the regimens. Through an online journal search, 59 articles were selected for the review. Literature searches were performed through PubMed, Medline, Ebsco Host, and CINAHL, with key search words of "Pediculosis capitis" and "head lice" in the title, abstract, and index. Meta-analyses and controlled clinical trials were viewed with greater weight if they had a large sample size, were statistically significant, and did not allude to bias. When resistant infestations are well-documented in a locality, changes to the treatment regimen are indicated, and alternative treatments should be considered. Recent studies and U.S. Food and Drug Administration (FDA) approvals have changed the available treatment options for Pediculosis capitis, including benzyl alcohol, topical ivermectin, spinosad, and the LouseBuster. Further, environmental management and prevention measures should be taken to avoid reinfestation and to prevent the spread of head lice. Continued study is recommended to establish long-term safety of new and alternative agents. PMID:26665422

    Full Text Available Antoni Bennassar, Ramon GrimaltDept of Dermatology, Hospital Clinic, University of Barcelona, Barcelona, SpainAbstract: Tinea capitis (TC is a common dermatophyte infection affecting primarily ­prepubertal children. The causative pathogens belong to only two genera: Trichophyton and Microsporum. Although there is a great local variation in the epidemiology of TC worldwide, T. tonsurans is currently the most common cause of TC with M. canis second. Even though there is an emerging number of anthropophilic scalp infections, M. canis remains the predominant causative organism in many countries of the Mediterranean basin, the most important dermatophyte carriers being stray cats and dogs as well as pet puppies, kittens and rabbits. TC always requires systemic treatment because topical antifungal agents do not penetrate down to the deepest part of the hair follicle. Since the late 1950s, griseofulvin has been the gold standard for systemic therapy of TC. It is active against dermatophytes and has a long-term safety profile. The main disadvantage of griseofulvin is the long duration of treatment required which may lead to reduced compliance. The newer oral antifungal agents including terbinafine, itraconazole, ketokonazole, and fluconazole appear to have efficacy rates and potential adverse effects similar to those of griseofulvin in children with TC caused by Trichophyton species, while requiring a much shorter duration of treatment. They may, however, be more expensive.Keywords: tinea capitis, children, fungal infection, greseofulvin, terbinafine, itraconazole, fluconazole, treatment, pediatric infection

    2010-02-01

    The head louse problem increases at all levels of the international societies due to activities or life conditions that lead to often hair contacts among people. Lice occur exclusively on humans. Thus, they avoid dropping down from a head and therefore accept even a bad smelling hair of new a host. Due to this behaviour, there are only a few products on the markets which dare to claim a repellency activity that protects humans from infestation with head lice. The present study shows that a combination of an extract of the seeds of the plant Vitex agnus castus (monk pepper) and the compound paramenthan-3,8-diol (which is also found in some plants, e.g. Eucalyptus) act synergistically and are able to protect human hair for at least 7 h from invasion of head lice (Pediculus humanus capitis). The recently developed product containing both compounds is named Licatack Preventive Spray. PMID:20054562

The causative dermatophytes vary with social status and geographical distribution. The incidence is high in developing countries due to factors like poverty compounded by overcrowding, improper hygiene and illiteracy. Tinea capitis is the most common dermatophytes infection of childhood, especially in school going children. It is self-limiting disease of childhood and seldom extends beyond puberty. India being a tropical developing country with high temperature and humidity favours superficial cutaneous mycotic infections. The objective of this study was to isolate and identify the dermatophytes causing tinea capitis. METHOD A prospective study was conducted from July 2013 to August 2015. The study included 90 clinically suspected cases of tinea capitis. Among the 90 clinically suspected cases, 51 cases showed mycological evidence of fungal infection. The confirmed positive cases were then speciated based on their cultural morphology and microscopy.

    Demographic, socio-economical, and environmental changes affecting prevalence of Pediculosis capitis. The aim of this study was to investigate the prevalence of P. capitis and external factors affecting the distribution of P. capitis. A total of 6004 primary-school students between 5 and 11 years were screened for P. capitis at 28 different primary-schools in Gaziantep, located in southeastern of Turkey, during different two education terms (First education term is in September 2013 to May 2014, second education term is in September 2014 and May 2015). The prevalence of P. capitis was found to be positive 1.5 % (90/6004) and 6.9 % (415/6004) in first education term and in second education term, respectively. In this study shown that the rate of P. capitis's prevalence was increased 5.4 % in Gaziantep. P. capitis is a neglected infestation and it has re-emerged in Gaziantep, located in the southeastern of Turkey. Health staff member must improve health education programs in primary-school students especially girl students. PMID:27038249

    While the impact of therapeutic levels of ionizing radiation during childhood on dental defects has been documented, the possible effect of low doses on dental health is unknown. The study aim was to assess the association between childhood exposure to low-moderate doses of therapeutic radiation and caries experience among a cohort of adults 50 years following the exposure. The analysis was based on a sample of 253 irradiated (in the treatment of tinea capitis) and 162 non-irradiated subjects. The decayed, missing, and filled teeth (DMFT) index was assessed during a clinical dental examination and questions regarding dental care services utilization, oral hygiene behavior, current self-perceived mouth dryness, socio-demographic parameters, and health behavior variables were obtained through a face-to-face interview. An ordered multivariate logistic regression model was used to assess the association of the main independent variable (irradiation status) and other relevant independent variables on the increase in DMFT. Mean caries experience levels (DMFT) were 18.6 ± 7.5 for irradiated subjects compared to 16.4 ± 7.2 for the non-irradiated (p = 0.002). Controlling for gender, age, education, income, smoking, dental visit in the last year, and brushing teeth behavior, irradiation was associated with a 72% increased risk for higher DMFT level (95% CI: 1.19-2.50). A quantification of the risk by dose absorbed in the salivary gland and in the thyroid gland showed adjusted ORs of 2.21 per 1 Gy (95% CI: 1.40-3.50) and 1.05 per 1 cGy (95% CI: 1.01-1.09), respectively. Childhood exposure to ionizing radiation (0.2-0.4 Gy) might be associated with late outcomes of dental health. In line with the guidelines of the American Dental Association, these results call for caution when using dental radiographs. PMID:26942172

    Background. Diagnosis of patchy hair loss in pediatric patients is often a matter of considerable debate among dermatologists. Trichoscopy is a rapid and noninvasive tool to detect more details of patchy hair loss. Like clinical dermatology, trichoscopy works parallel to the skin surface and perpendicular to the histological plane; like the histopathology, it thus allows the viewing of structures not discovered by the naked eye. Objective. Aiming to compare the different trichoscopic features of tinea capitis and alopecia areata in pediatric patients. Patients and Methods. This study included 40 patients, 20 patients with tinea capitis and 20 patients with alopecia areata. They were exposed toclinical examination, laboratory investigations (10% KOH and fungal culture), and trichoscope examination. Results. Our obtained results reported that, in tinea capitis patients, comma shaped hairs, corkscrew hairs, and zigzag shaped hairs are the diagnostic trichoscopic features of tinea capitis. While in alopecia areata patients, the most trichoscopic specific features were yellow dots, exclamation mark, and short vellus hairs. Conclusion. Trichoscopy can be used as a noninvasive tool for rapid diagnosis of tinea capitis and alopecia areata in pediatric patients. PMID:25024698

    Full Text Available Rhythmic movement disorder, also known as jactatio capitis nocturna, is an infancy and childhood sleep-related disorder charactherized by repetitive movements occurring immediately prior to sleep onset and sustained into light sleep. We report a 19-year-old man with a history of headbanging and repetitive bodyrocking since infancy, occurring on a daily basis at sleep onset. He was born a premature baby but psychomotor milestones were unremarkable. Physical and neurological diagnostic workups were unremarkable. A hospital-based sleep study showed: total sleep time: 178 min; sleep efficiency index 35.8; sleep latency 65 min; REM latency 189 min. There were no respiratory events and head movements occurred at 4/min during wakefulness, stages 1 and 2 NREM sleep. No tonic or phasic electromyographic abnormalities were recorded during REM sleep. A clinical diagnosis of rhythmic movement disorder was performed on the basis of the clinical and sleep studies data. Clonazepam (0.5 mg/day and midazolam (15 mg/day yielded no clinical improvement. Imipramine (10 mg/day produced good clinical outcome. In summary, we report a RMD case with atypical clinical and therapeutical features.

    A survey of 308,101 primary school children in Peninsular Malaysia conducted in 1979 by the School Health Services, Ministry of Health, Malaysia, revealed that 10.7% of children were infested with Pediculus humanus capitis. The prevalence rate was higher in the economically less advanced states of Terenganu (34%), Kelantan (23%), and Perlis (21%) than in the other states (4-13%). Of 14,233 school children examined in the State of Melaka, 26% of Indians, 18.7% of Malays, 6.1% of Europeans, and 0.7% of Chinese had pediculosis. The prevalence rate, which has remained unchanged over the past 5 years, does not appear to vary with age but is higher in children with long hair and those from the lower socioeconomic groups. Boys have a lower infestation rate than do girls. The higher incidence in Indians and Malays correlates well with their lower socioeconomic status in the community, and their cultural habit of maintaining longer hair than do the Chinese. The difference become less apparent in the higher socioeconomic groups. PMID:7258487

    Full Text Available Ventrodorsal pelvic radiographs were made of 32 adult dogs under general anaesthesia. The hip joints were evaluated according to the severity of osteoarthritic changes graded as 0, 1, 2 or 3. The dogs were euthanased, the hip joints opened and the ligamentum capitis femoris dissected out in toto. The volume of each ligament was determined using a water displacement technique and the mean volume compared to the four radiographic grades of osteoarthritis. There was an inverse correlation (r = -0.75 between the mean volume of the ligamentum capitis femoris and the increasing severity of osteoarthritis as assessed by radiography. The results confirmed the crucial role of radiography in the clinical evaluation of hip dysplasia and osteoarthritis in the adult dog. Assessment of the volume of the ligamentum capitis femoris revealed that it is an important tool for research in canine hip dysplasia and osteoarthritis.

    OBJECTIVES Although topical agents for the treatment of tinea capitis decrease viable fungal elements and reduce shedding, their use as a prophylactic agent has not been investigated. This study evaluated the effectiveness of a prophylactic ketoconazole shampoo (Nizoral 2%) protocol to reduce the number of clinically evident tinea capitis infections in a high-risk African American, urban population. METHODS We conducted a retrospective analysis of a ketoconazole prophylaxis protocol that was implemented at an urban pediatric clinic for medically fragile children. Patients at high risk for tinea capitis received twice-weekly ketoconazole shampoo. The primary outcome of the study was a reduction in the number of documented tinea capitis infections between the 12-month preprotocol and 12-month postprotocol periods. A secondary outcome included the evaluation of predisposing risk factors for acquiring tinea infections. RESULTS Ninety-seven patients, with a mean age of 8.06 years, were included. Most patients (78%) were African American. There were a total of 13 tinea capitis infections during the 12-month preprotocol period. During the 12-month postprotocol period, 41 infections were documented: 37 (90.2%) in the prophylaxis group and 4 (9.8%) in the nonprophylaxis group. The average numbers of per-patient infections in the postprotocol period were 0.79 and 0.08 in the prophylaxis and nonprophylaxis groups, respectively. Initiation of prophylaxis did not reduce tinea capitis infections (p=NS). Previous history of infection and a high level of care were significant predictors of infections (p<0.05). CONCLUSIONS Improved hygiene, adherence to prescribed treatment regimens, and prevention of recurrent environmental exposure to surviving fomites should be stressed in high-risk patients and supersede the need for an antifungal (ketoconazole shampoo) prophylaxis protocol.

    Full Text Available Background: Pediculosis capitis is a ubiquitous parasitic skin disease associated with intense pruritus of the scalp. In developing countries it frequently affects children and adults, but epidemiological data at the community level are rare. Objectives: To assess prevalence and risk factors associated with pediculosis capitis in a resource-poor community in Lima, Peru. Materials and Methods: In total, 736 persons living in 199 households in a circumscribed neighbourhood were examined for head lice and nits by visual inspection. At the same time, socio-demographic data were collected using a structured questionnaire. Variables associated with pediculosis were identified by performing a bivariate analysis, followed by a multivariate logistic regression analysis. Results: Prevalence of pediculosis capitis was 9.1% (95% confidence interval (CI: 7.0-11.2 % in the general population and 19.9% (CI: 15.4-24.4% in children ≤15 years of age. Multivariate analysis showed that pediculosis capitis was significantly associated with age ≤ 15 years (OR: 16.85; CI:7.42-38.24, female sex (OR: 2.84; CI: 1.58-5.12, household size of >4 persons (OR: 1.98; CI: 1.11-3.55, low quality of house construction material (OR:2.22; CI: 1.20-4.12, and presence of animals in the household (OR: 1.94; CI: 1.11-3.39. Conclusion: Pediculosis capitis was a very common disease in the studied community in Lima, Peru. Our logistic regression analysis affirms that young age is the most important risk factor for pediculosis capitis. Moreover, female sex, large household size, living in wooden houses and the presence of animals were identified as being significantly associated with head lice infestation.

    Tinea capitis is a scalp infection caused by fungi. In Brazil, the main causative agents are Microsporum canis and the Trichophyton tonsurans. Etiological diagnosis is based on suggestive clinical findings and confirmation depends on the fungus growth in culture. However, it is not always possible to perform this test due to lack of availability. We reveal the dermoscopic findings that enable distinction between the main causative agents of Tinea capitis, M. canis and T. tonsurans. The association of clinical and dermatoscopic findings in suspected Tinea capitis cases may help with the differential diagnosis of the etiological agent, making feasible the precocious, specific treatment.

    The myodural bridge was first described by Hack in 1995 and was thought to be related to chronic cervicogenic headaches. For a long time, few studies revealed the patterns of the myodural bridge considering the rectus capitis posterior minor muscle. In this study, P45 plastination technology and anatomical dissection were performed on head specimens, and four different terminal region types of the rectus capitis posterior minor muscle were observed, including the posterior atlanto-occipital interspace, posterior arch of the atlas and posterior atlanto-axial interspace. We propose that the myodural complex structures in the posterior atlanto-occipital and posterior atlanto-axial interspace have cooperative effects on cerebrospinal fluid and work together. This force might be an important source for the circulation of cerebrospinal fluid. PMID:25859757

    The human head louse, Pediculus humanus capitis (Anoplura: Pediculidae), is an ectoparasite confined to the scalp and human hairs. The repeated use of insecticides for the control of head lice during past decades has resulted in the development of marked levels of resistance. Natural compounds such as essential oils (EOs) have been suggested as alternative sources for insect control agents. In order to introduce a new pediculicide based on EOs, the effectiveness of the product and their effects on human being must be analyzed. In consequence, the biological activity of EOs from the leaves and fruits of Schinus areira (Anacardiaceae) and the leaves of Thymus vulgaris (Lamiaceae), Aloysia polystachya and Aloysia citriodora (Verbenacea) were evaluated against the eggs and adults of P. humanus capitis by fumigant and contact toxicity bioassays. Additionally, dermal corrosion/irritation tests were performed on New Zealand albino rabbits. In a fumigant bioassay, EOs from the leaves and fruits of S. areira were the most toxic against P. humanus capitis adults while these EOs and T. vulgaris were the most effective against the eggs. In contact bioassay, the EO from T. vulgaris was the most toxic against both stages. In the corrosion/irritation tests, the EOs did not produce dermal effects. According to the results, the essential oils from the leaves of T. vulgaris would be a valid tool for the management of P. humanus capitis. This EO produces a high knockdown effect in adults (followed by mortality) and toxicity in the eggs when it is applied for 21 min at a low concentration. PMID:26462802

    Tinea capitis remains a common public health problem worldwide especially in developing areas. Aetiologic agents and clinical pattern vary with geography and history of socioeconomic conditions. Three community surveys and a prospective study were carried out over the past 50 years (1965-2014) in the Qingyunpu District of Nanchang, Southern China. Clinical presentation and spectrum of aetiological agents were monitored to understand the evolution of tinea capitis. In 1965 favus was highly epidemic and Trichophyton schoenleinii presented as the overwhelming aetiological agents of scalp infection in the study area, with a prevalence of 3.41% of the population. During a governmental campaign to eliminate tinea capitis initiated in mid of 1960s, favus was successfully controlled and the prevalence decreased to less than 0.01% in 1977. After that period, clinical presentation and spectrum of fungi changed with social development. Trichophyton schoenleinii was replaced by Trichophyton violaceum and Trichophyton mentagrophytes. Nowadays, the species corresponds with a dominant black dot type of tinea capitis in the Nanchang area. The prevalence of causative agents of tinea capitis is not only related to geography but also to socioeconomic factors. Multiple factors have to be considered for the management for control of this disease. PMID:25756741

    International Nuclear Information System (INIS)

    Occurrence of basal cell carcinoma (BCC) following radiotherapy for tinea capitis is well known. The aim of this study was to specify the clinical and histological features of these BCC seen in 33 patients (1995 000). Twenty seven men and six women were diagnosed with BCC. The age of onset varied between 32 an 62 years. Radiotherapy was received between 5 and 17 years of age. The interval between irradiation and the onset of carcinoma varied between 21 and 51 years. Total number of lesions was 55. Forty percent of BCC occurred on the occipital area, the number varied from 1 to 5 and the size from 2 to 45 mm. Clinically, the nodular type was found in 51% of cases. Pigment was present in 64% of cases. Histological study showed a nodular aspect in 76% and pigmentation in 63% of cases. Nodular and pigmented type were the predominant BCC occurring after radiotherapy for tinea capitis in our series. In the literature, BCC are the most frequent carcinomas occurring after radiotherapy (70-100%). Pigmentation was not described in other series. The nodular histological form was the most frequent.

    The deep cervical extensor, semispinalis cervicis, displays changes in behaviour and structure in people with chronic neck pain yet there is limited knowledge on how activation of this muscle can be emphasized during training. Using intramuscular electromyography (EMG), this study investigated the activity of the deep semispinalis cervicis and the superficial splenius capitis muscle at two spinal levels (C2 and C5) in ten healthy volunteers during a series of neck exercises: 1. Traction and compression, 2. Resistance applied in either flexion or extension at the occiput, at the level of the vertebral arch of C1 and of C4, and 3. Maintaining the neck in neutral while inclined on the elbows, with and without resistance at C4. The ratio between semispinalis cervicis and the splenius capitis EMG amplitude was quantified as an indication of whether the exercise could emphasize the activation of the semispinalis cervicis muscle relative to the splenius capitis. Manual resistance applied in extension over the vertebral arch emphasized the activation of the semispinalis cervicis relative to the splenius capitis at the spinal level directly caudal to the site of resistance (ratio: 2.0 ± 1.1 measured at C5 with resistance at C4 and 2.1 ± 1.2 measured at C2 with resistance at C1). This study confirmed the possibility of emphasizing the activation of the semispinalis cervicis relative to the splenius capitis which may be relevant for targeted exercise interventions for this deep extensor muscle. Further studies are required to investigate the clinical efficacy of these exercises for people with neck pain. PMID:25935795

    We present here the first in vivo optical coherence tomography (OCT) images of human dental tissue. A novel dental optical coherence tomography system has been developed. This system incorporates the interferometer sample arm and transverse scanning optics into a handpiece that can be used intraorally to image human dental tissues. The average imaging depth of this system varied from 3 mm in hard tissues to 1.5 mm in soft tissues. We discuss the application of this imaging system for dentistry and illustrate the potential of our dental OCT system for diagnosis of periodontal disease, detection of caries, and evaluation of dental restorations.

    Full Text Available Acute hematogenous osteomyelitis (AHOM of the acetabulum is a rare condition in children and usually caused by Staphylococcus aureus. We present an 11-year-old soccer athlete who suffered from acute osteomyelitis involving the acetabulum caused by S. capitis, a normal flora of the human skin but never reported in this condition. The disease was associated with repetitive skin injuries of the knee and potential osseous microtrauma of the hip joint by frequent rigorous exercise. This unusual case suggests that osseous microtrauma of the acetabulum, in addition to repetitive skin injuries, allowed normal skin flora to colonize to the ipsilateral acetabulum, which served as a favorable niche and subsequently led to AHOM.

    Full Text Available Perifoliculitis capitis abscedens et suffodiens, dissecting folliculitis, dissecting cellulitis, or Hoffman disease is a rare, inflammatory and chronic condition, which affects the scalp of young black men, mainly characterized by the appearance of nodules and abscesses that drain purulent material with fistulas and pathways, leading ultimately to scarring alopecia. At present, this condition is defined as a primary disorder of follicular keratinization, being part of the triad or tetrad of follicular occlusion. One third of the cases are associated with acne conglobata as a primary event. Management, frustrating for many years, is promising with the successful use of isotretinoin and a combination of medications that intervene each of its physiopathological principles.

This study aimed to determine the prevalence of head pediculosis among school children in ur­ban and rural areas of Fars Province, southern Iran."nMethods: All school children of age 6-11 yr from both genders in all urban and rural areas of the province were screened for head louse infestation by examination of their hair and scalps. Parents of all infested children were also exam­ined. The study was repeated in different seasons in the same areas. Moreover, infested children were treated with 5% permethrin shampoo and re-examined one week later for any relapse."nResults: The general prevalence of head louse infestation in primary school students was 0.49% in autumn, 0.37% in win­ter and 0.20% in spring. In the mentioned seasons, the prevalence of P. capitis was higher among females and in ru­ral areas (P=0.001. Although treatment with permethrin shampoo failed in females, it was successful in all infected males from both regions in autumn and spring and in males from urban areas in winter."nConclusion: Head louse infestation is uncommon among Fars Province school children in rural and urban areas and should not be considered a public health priority. However, due to the higher prevalence of pediculosis in low socioeco­nomic group and rural area in our region, it seems that health promotion, particularly early detection and effec­tive management strategies should target this group in the province.

    Full Text Available Introducción: en Cuba se reportaron altas frecuencias de pediculosis capitis desde finales de los años noventa, particularmente en algunos grupos de escolares y sus convivientes. Estos últimos se involucran en la cadena de transmisión de esos insectos y pueden desempeñar, en la actualidad, una función importante como reservorios del parásito. Objetivo: reportar la eficacia del tratamiento con añil cimarrón en una paciente infestada de Pediculus capitis. Métodos: se describe un caso de infestación persistente con pediculosis capitis en una paciente de 55 años de edad, tratada con solución de permetrina 1 % y posteriormente con tintura de añil cimarrón 5 %. Resultados: la identificación microscópica de adultos y estadios pre-adultos del parásito confirmaron la presencia de Pediculus capitis. El tratamiento del cabello con permetrina 1 % no fue eficaz en 2 aplicaciones realizadas. Como alternativa de tratamiento, se aplicó tintura de añil 5 %, lo que permitió disminuir la población de ectoparásitos adultos y logró eliminar la infestación después de una segunda aplicación, con la constante extracción de las liendres realizada por el personal paramédico encargado del caso. Conclusión: la aplicación de este procedimiento inocuo podría servir como alternativa terapéutica para esta afección.Introduction: pediculosis capitis was very frequently reported in Cuba since the end of the 90's, particularly in some groups of school children and their relatives.

    This study was aimed to explain the formation mechanisms of corkscrew hairs and cigarette-ash-shaped hairs observed by dermoscopy of tinea capitis. In the present work, the ultrastructure of the involved hairs collected from a girl with tinea capitis caused by Trichophyton violaceum was observed by scanning electron microscope (SEM) and transmission electron microscope (TEM). SEM observation of the corkscrew hair revealed bent hair shaft and asymmetrically disrupted cuticle layer. TEM findings demonstrated the hair shaft became weak. The corkscrew hairs closely covered by scales on the scalp were observed under dermoscopy. We speculate that the formation of corkscrew hairs is a result of a combination of internal damage due to hair degradation by T. violaceum and external resistance due to scales covering the hair. SEM observation of the cigarette-ash-shaped hair revealed irregularly disrupted and incompact end, which might represent the stump of the broken corkscrew hair after treatment. PMID:26301780

    Tinea capitis is unusual and often misdiagnosed in healthy adults. We report a case of a healthy woman with a several-year history of asymptomatic, bizarre-shaped, non-scarring alopecia. She had used over-the-counter ketoconazole shampoo regularly for a long time. An initial potassium hydroxide preparation showed negative result for fungal organism. The scalp biopsy revealed endothrix infection, and dermoscopic examination demonstrated the comma hair and corkscrew hair signs. The fungal culture showed Trichophyton tonsurans. The daily use of antifungal shampoo could be the important factor to conceal clinical and laboratory findings for diagnosis of T. tonsurans tinea capitis in our case, which required high clinical suspicion and histopathology and dermoscopic examinations.

    Dental radiology is the core diagnostic modality of veterinary dentistry. Dental radiographs assist in detecting hidden painful pathology, estimating the severity of dental conditions, assessing treatment options, providing intraoperative guidance, and also serve to monitor success of prior treatments. Unfortunately, most professional veterinary training programs provide little or no training in veterinary dentistry in general or dental radiology in particular. Although a technical learning curve does exist, the techniques required for producing diagnostic films are not difficult to master. Regular use of dental x-rays will increase the amount of pathology detected, leading to healthier patients and happier clients who notice a difference in how their pet feels. This article covers equipment and materials needed to produce diagnostic intraoral dental films. A simplified guide for positioning will be presented, including a positioning "cheat sheet" to be placed next to the dental x-ray machine in the operatory. Additionally, digital dental radiograph systems will be described and trends for their future discussed. PMID:19410234

    Full Text Available Background Human head lice infestations caused by Pediculus capitis are a common health problem in school aged children in many parts of the globe. Its transmission occurs directly, mostly by head to head contact, and causes scalp itching. This insect is not known to be the vector of any human disease. Objectives This descriptive-analytical study was conducted in order to determine the prevalence of pediculosis, as well as some effective treatments, among pupils in the primary schools of Glogah county in the Mazandaran province of Iran, during the 2009-2010 school year. Materials and Methods A total of three-hundred students in the first through fifth grades in boys’ and girls’ primary schools were selected via multistage, systematic, cluster, random sampling in the urban and rural areas of Glogah county. They were examined for live lice or nits by experienced educators, while a questionnaire was used to record data on the demographic features and other related information of each student. These data were compared using a chi square analysis (SPSS software, and a P value of less than 0.05 was considered to be significant. Results Based on a total of 300 pupils, 17 of them (5.7% were infested with Pediculus capitis. The prevalence rate was 6.8% in the boys and 4.8% in the girls, while the rate of infestation was 7.7% in the urban areas and 3.4% in the villages. Those children between 9 and 10 years old showed the highest prevalence rate (7.4%. There was a significant association between pediculosis and a prior infestation, number of comb uses per day, frequency of hair washing (per week, having a hygiene teacher, sharing common instruments, health care of the children, children living with parents, knowledge of pediculosis, and the spacing of the children in each class. Conclusions The results showed that the prevalence of pediculosis among the Glogah county primary school students was less than the average percentages observed in other

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

    A 28-month-old boy developed a cutaneous and subcutaneous lesion of the scalp together with alopecia. Treatment with sulfadiazine silver ointment and oral administration of cefaclor failed. The boy lived on a farm where cows and calves were present. He presented with a 5 cm erythematous, erosive, edematous, and sharply defined lesion with yellow crusts and circumscribed alopecia on the temporoparietal scalp. Peripheral hairs were easily epilated. Swabs from the wound revealed cMRSA (community acquired methicillin-resistant Staphylococcus aureus, Panton Valentine Leukocidin [PVL] toxin negative). There was no improvement after treatment with cefuroxime intravenously over 3 days. Therapy was changed to vancomycin and fosfomycin. Because of the purulent abscess, surgical incision was performed. PCR (polymerase chain reaction)-Elisa assay detected Trichophyton (T.) interdigitale-DNA from wound secretion and skin biopsy. Because of the clinical and molecular diagnosis of tinea capitis, oral antifungal therapy with fluconazole 5 mg kg(-1) body weight was started, along with cotrimoxazole and fosfomycin for the cMRSA. After 4 weeks incubation, the causative agent T. verrucosum was grown on culture and its identity confirmed by sequencing of the "internal transcribed spacer" (ITS) region of the ribosomal DNA. After 4 weeks of fluconazole, the lesion was nearly healed. PMID:22406762

  15. Mental function following scalp X irradiation for tinea capitis in childhood

    International Nuclear Information System (INIS)

    One of the populations available for study of long-term radiation effects is comprised of persons given x-ray epilation therapy in childhood for ringworm of the scalp (a method for treatment no longer used). Groups of irradiated tinea capitis patients and controls have been identified and followed for an average post-treatment time of 20 to 25 years at two locations: New York University Medical Center and Chaim Sheba Medical Center in Israel. The Bureau of Radiological Health has supported both of these investigations. The principal endpoints under investigation have been neoplasms and central nervous system effects, as reported in a number of publications. With regard to neoplasms, an excess of tumors of the head and neck was found in the irradiated individuals of both groups but in New York the excess tumors were benign (except for skin cancer), whereas in Israel there was also a marked excess of cancers of the brain, thyroid and parotid. With respect to nervous, mental and behavioral effects, the New York investigators found a higher incidence of treated psychiatric disorders among the irradiated which persisted during an observation period of about 30 years. The excess was seen only in white study subjects; no difference between irradiated and controls was observed among blacks with regard to treated mental illness or psychologic testing and psychiatric evaluation

    We studied the profile of permethrin resistance in populations of head lice infesting children 6-12 yr old in schools and their homes in and around Buenos Aires, Argentina. Five permethrin-resistant populations with different levels of resistance were collected: Hogar Loyola (HL), Republica de Turquia (RT), Hogar Mitre (HM), Guardia de Honor (GH), and Ricardo Guiraldes (RG). One susceptible population, Bandera Argentina (BA), also was collected. Their level of resistance was evaluated, and results showed resistance ratios of 13 for HL, 16 for RT, 22 for HM, 61 for GH, and 69 for RG. To elucidate the possible involvement of the cytochrome P450 monooxygenase system in conferring permethrin resistance, ethoxycoumarin-O-deethylase (ECOD) activity was measured in abdomens of individual third instars and adults by using a fluorometric assay. The ECOD activity was lower in the susceptible BA population (4.7 ng per louse) than in the resistant ones (13.7 ng per louse for RG, 12.3 ng per louse for GH, 8.6 ng per louse for RT, and 8.2 ng per louse for HL). ECOD activity was significantly correlated with the level of resistance in the field populations (r = 0.97, P = 0.0009), suggesting a role for cytochrome monooxygenase P450 system in permethrin resistance by head louse, Pediculus humanus capitis De Geer.

    Full Text Available Objective: The aim of the presented study was determine the prevalence of Pediculosis capitis and factors related to the treatment success in a public primary school situated in an area having a low socio-economic status in the city of Kocaeli. Materials and Methods: A total of 414 students attending at the first grade of a public primary school in Kocaeli and 267 family members of the students with head lice and/or nits were screened. Students and their family members were examined by visual inspection and dermoscopic examination whether they had head lice and/or nits. The data were collected about some socio demographic characteristics of children’ and those of their family members with active Pediculosis capitis and shampoos with 1% permethrin was used to get rid of Pediculosis capitis. After two weeks, people who had received treatment were re-examined and factors related to the successful treatment were evaluated. Results: The prevalence of pediculosis capitis was 14.3% in school children and 13% in their family members. The prevalence was statistically significant with education levels of the mothers and fathers, social security of family and by gender. The treatment was successful in 38 of school children (66%, and in 10 of their family members (29% with pediculosis capitis. The success of the treatment was no statistically significant in gender, education level of the mothers and fathers, having social security and income. It was noticed that successful treatment was correlated with proper use of the shampoo and proper mechanical cleaning. Conclusions: Head lice is a public health problem that concerns both the school children and their family members. School children who were infested with Pediculosis capitis and their families should be periodically screened and should be immediately and simultaneously treated to preventing reinfestation.

    Natural compounds have been suggested as alternative sources for pediculosis capitis control. We aimed to investigate the chemical composition and evaluate the pediculicidal activity of spearmint, clove, cassia, thyme, eucalyptus, and anise essential oils in addition to sesame oil against human head lice in vitro. A filter paper contact bioassay method was used by applying 0.25 and 0.5 mg/cm(2) of each tested oil to filter paper in Petri dishes with 15 females head lice and another with ten nits. The lice mortalities were reported every 5 min for 180 min. The percentage of inhibition of hatch (PIH) was used to calculate ovicidal activity by daily microscopic inspections 5 days after the hatching of controls. Comparison with the widely used pediculicide (malathion) was performed. The most effective essential oil was spearmint followed by cassia and clove with KT50 values of 4.06, 7.62, and 12.12 at 0.5 mg/cm(2) and 8.84, 11.38, and 19.73 at 0.25 mg/cm(2), respectively. Thyme, eucalyptus, and anise were also effective adulticides with KT50 values of 18.61, 32.65, and 37.34 at 0.5 mg/cm(2) and 29.92, 43.16, and 45.37 at 0.25 mg/cm(2), respectively. Essential oils were also successful in inhibiting nymph emergence. Spearmint oil was the most effective, with a complete inhibition of emergence at 0.5 mg/cm(2). Sesame fixed oil did not show any adulticidal or ovicidal activity against head lice in vitro. The observed insecticidal activity was comparable to malathion. The results herein described the effectiveness of these essential oils as potential pediculicides for head lice control. Incorporation of essential oils in pediculicide formulations needs proper formulation and clinical trials. PMID:27112758

    Effective management of neck pain requires detailed knowledge of cervical muscle structure and function. Information on muscle fibre type assists in determining function; few data exist on the fibre type composition of many cervical muscles. The purpose of this study was to investigate the fibre type composition of longus capitis (LCa) and longus colli (LCo) to provide a better understanding of their function. Muscle sections were harvested unilaterally from LCa (C2-C7) and LCo (C3, C6, T1) in seven female cadavers (mean age 86 ± 9 years). Immunohistochemistry was used to identify type I and type II fibres, and stereology (random systematic sampling) used to determine fibre numbers. Data were assessed using descriptive statistics and one-way ANOVA (significance P < 0.05). Fifty-two sections were assessed (82,785 fibres; mean 1,592 ± 927 per section). LCa had a significantly greater proportion of type I fibres than LCo (64.3 % vs 55.7 %, P = 0.011). The percentage of fibre types varied significantly between individuals in LCa, but not LCo. No significant difference was found in the proportion of type I fibres between cervical levels for either LCa or LCo. LCa and LCo appear functionally different in elderly females, with LCa potentially having a more postural role (higher type I fibre proportion). Fibre types were homogenous throughout each muscle, indicating that contractile function is similar across the length of individual muscles. Further studies across a larger age-span and in males are required to determine whether results are representative of other populations. PMID:25794488

    Ten years have passed since the first articles appeared in this new field. The qualities of the laser light together with the need of contactless 3-D measurements for different dental purposes seemed to be extremely promising, but still just a few scientists have used the method and mostly for laboratory studies. For some reason there has been a preponderance for orthodontic measurements. This seems to be a bit peculiar from holographic view compared with measurements for engineering purposes, which usually are made on metals. So naturally holography can become a clinical tool for measurements in the field of fixed bridges, removable partial dentures and implants. One of the problems is that the need for holography in dental research must be fulfilled in collaboration with physicists. Only a two-way communication during an entire experiment can balance both technical and odontological demands and thus give practical and clinical important results. The need for an easy way of handling the evaluation to get all required information is another problem and of course the holographic equipment must be converted to a box easy to handle for everyone. At last the position of dental holography today is going to be carefully examined together with an attempt to look into the hopefully exciting and not to utopic future for this research field.

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

    Full Text Available Background: Pediculosis capitis is cosmopolitan health problem. In addition to its physical problems, its psycho­logical effects especially on pupils are more important. This study was conducted to determine the Pediculosis capitis among primary school pupils and also find out the role of probable related risk factors in Urmia city, Iran 2010.Methods: 35 primary schools of Urmia City according to the defined clusters randomly have been selected during 2010. 2040 pupils (866 boys and 1174 girls were included and examined individually and privately by experts. Presence of adult or immature lice or having nits less than 1 cm from the hair basis were defined as positive.Data about demographic features and factors which their effect should be determined were recorded in standard questionnaire. Data were analyzed by SPSS software with proper statistical test.Results: Infestation was determined around 4%. Girls show significantly greater infestation. The availability of suit­able warm water for bathing and hair length (separately in girls and boys are significantly related to infestation load as well as infestation among different age groups.There was no significant relation between parent’s education and job and infestation as well as bathing repetition per week and the kind of energy source which they have. Also there is no significant correlation between educational grades and head lice infestation.Conclusion: The head louse pediculosis is a health problem and remains a health threatening for school chil­dren.Effective risk factors should be determined carefully and regionally. Proper training plays a great role in order to prevent and control the problem

    Full Text Available Speciation is always a contentious and challenging issue following with the presence of gene flow. In Gossypium, there are many valuable resources and wild diploid cotton especially C and B genome species possess some excellent traits which cultivated cotton always lacks. In order to explore character transferring rule from wild cotton to upland tetraploid cotton, the [G. capitis-viridis × (G. hirsutum × G. australe2] triple hybrid was synthesized by interspecies hybridization and chromosome doubling. Morphology comparisons were measured among this hybrid and its parents. It showed that trispecific hybrid F1 had some intermediate morphological characters like leaf style between its parents and some different characters from its parents, like crawl growth characteristics and two kind flower color. It is highly resistant to insects comparing with other cotton species by four year field investigation. By cytogenetic analysis, triple hybrid was further confirmed by meiosis behavior of pollen mother cells. Comparing with regular meiosis of its three parents, it was distinguished by the occurrence of polyads with various numbers of unbalanced microspores and finally generating various abnormal pollen grains. All this phenomenon results in the sterility of this hybrid. This hybrid was further identified by SSR marker from DNA molecular level. It showed that 98 selected polymorphism primers amplified effective bands in this hybrids and its parents. The genetic proportion of three parents in this hybrid is 47.8% from G. hirsutum, 14.3% from G. australe, 7.0% from G. capitis-viridis, and 30.9% recombination bands respectively. It was testified that wild genetic material has been transferred into cultivated cotton and this new germplasm can be incorporated into cotton breeding program.

    2015-01-01

    Dental caries continues to be the most prevalent bacteria-mediated non-contagious disease of humankind. Dental professionals assert the disease can be explained by poor oral hygiene and a diet rich in sugars but this does not account for caries free individuals exposed to the same risk factors. In order to test the hypothesis that amount of amelogenin during enamel development can influence caries susceptibility, we generated multiple strains of mice with varying levels of available amelogenin during dental development. Mechanical tests showed that dental enamel developed with less amelogenin is "weaker" while the dental enamel of animals over-expressing amelogenin appears to be more resistant to acid dissolution.

  20. Effectiveness of isopropyl myristate/cyclomethicone D5 solution of removing cuticular hydrocarbons from human head lice (Pediculus humanus capitis

    Directory of Open Access Journals (Sweden)

    Barnett Eric

    2012-09-01

    Full Text Available Abstract Background In the treatment of human head lice infestation, healthcare providers are increasingly concerned about lice becoming resistant to existing pesticide treatments. Traditional pesticides, used to control these pests, have a neurological mechanism of action. This publication describes a topical solution with a non-traditional mechanism of action, based on physical disruption of the wax layer that covers the cuticle of the louse exoskeleton. This topical solution has been shown clinically to cure 82% of patients with only a 10-minute treatment time, repeated once after 7 days. All insects, including human head lice, have a wax-covered exoskeleton. This wax, composed of hydrocarbons, provides the insect with protection against water loss and is therefore critical to its survival. When the protective wax is disrupted, water loss becomes uncontrollable and irreversible, leading to dehydration and death. A specific pattern of hydrocarbons has been found in all of the head louse cuticular wax studied. Iso-octane effectively removes these hydrocarbons from human head lice’s cuticular wax. Methods A method of head louse cuticle wax extraction and analysis by gas chromatography was developed. Human head lice (Pediculus humanus capitis were collected from infested patients and subjected to any of three extraction solvents comprising either the test product or one of two solvents introduced as controls. A gas chromatograph equipped with a flame ionization detector (GC/FID was used to determine the presence of hydrocarbons in the three head lice extracts. Results In the study reported herein, the test product isopropyl myristate/cyclomethicone D5 (IPM/D5 was shown to perform comparably with iso-octane, effectively extracting the target hydrocarbons from the cuticular wax that coats the human head louse exoskeleton. Conclusions Disruption of the integrity of the insect cuticle by removal of specific hydrocarbons found in the cuticular wax

    Full Text Available Among various dental materials and their successful applications, a dental implant is a good example of the integrated system of science and technology involved in multiple disciplines including surface chemistry and physics, biomechanics, from macro-scale to nano-scale manufacturing technologies and surface engineering. As many other dental materials and devices, there are crucial requirements taken upon on dental implants systems, since surface of dental implants is directly in contact with vital hard/soft tissue and is subjected to chemical as well as mechanical bio-environments. Such requirements should, at least, include biological compatibility, mechanical compatibility, and morphological compatibility to surrounding vital tissues. In this review, based on carefully selected about 500 published articles, these requirements plus MRI compatibility are firstly reviewed, followed by surface texturing methods in details. Normally dental implants are placed to lost tooth/teeth location(s in adult patients whose skeleton and bony growth have already completed. However, there are some controversial issues for placing dental implants in growing patients. This point has been, in most of dental articles, overlooked. This review, therefore, throws a deliberate sight on this point. Concluding this review, we are proposing a novel implant system that integrates materials science and up-dated surface technology to improve dental implant systems exhibiting bio- and mechano-functionalities.

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

    In the appraisal of head lice outbreak, in addition to socioeconomic factors and availability of health care services, environmental conditions of the households must be taken into account. However, interviewing with children or mailing questionnaires to families may not reflect the actualities. Therefore, in this study, all the inclusive factors which may be associated with head lice outbreak were thoroughly and closely investigated. The data were collected by examining students at schools and surveying patients' households. A questionnaire concerning children's personal hygienic practices, family features, and environmental conditions of the households was filled out during the close assessment of the residential area. The overall prevalence of head lice was obtained as 5.9%, and the difference was not significant within the urban (5.1%) and rural (6.1%) communities. Overall, the number of infested students was more frequent in girls (6.6%) than boys (2.8%), but the difference was not significant. The highest infestation rate was obtained in the examined students whose fathers were unemployed, farmer, and herdsman. Family income showed greater correlation with the prevalence of pediculosis capitis. A high frequency of pediculosis capitis was identified among the students who were sharing individual items with siblings. Assessment of households showed that room flooring material and keeping animals at home were highly correlated with head lice prevalence. Households should be informed that infestations happen, irrespective of socioeconomic status. However, the physical and environmental conditions of living areas and households play an important role in head lice prevention. PMID:26276644

  10. Skin dose and response for the head and neck in patients irradiated with x-ray for tinea capitis: implications for environmental radioactivity

    International Nuclear Information System (INIS)

    The dose delivered to the skin of the head and neck in patients treated with x-ray irradiation for childhood tinea capitis was reconstructed. This was possible by utilizing a phantom made from the skull of a seven year old child and irradiating it with the same technique and x-ray machine used in tinea capitis therapy two to four decades ago. Seventy-eight basal cell carcinomas (BCC) have appeared so far in 40 of 1727 irradiated white children and none in 500 irradiated black children. The dose distribution over the face and scalp is used to estimate the risk of BCC per person per rad. These results must be considered preliminary due to the relatively young age of the irradiated group (<50 years) at the present time. From the decreased risk per rad for the portion of the scalp that is hair covered, it appears that environmental ultraviolet radiation may play a key role in the expression of BCC. A cumulative hazard plot is utilized to tentatively extend the data to lifetime risk of 0.003 per rad with an upper limit of 0.006 per rad. Environmental radiation dose to the skin possibly account for 20% of observed BCC if this tentative risk estimate is valid

    In 2005, Public Act No. 161 (PA 161) was passed in Michigan, allowing dental hygienists to practice in approved public dental prevention programs to provide services for underserved populations while utilizing a collaborative agreement with a supervising dentist. The aims of this study were to assess how well dental and dental hygiene students and faculty members and practicing dental hygienists have been educated about PA 161, what attitudes and knowledge about the act they have, and how interested they are in additional education about it. University of Michigan dental and dental hygiene students and faculty members, students in other Michigan dental hygiene programs, and dental hygienists in the state were surveyed. Respondents (response rate) were 160 dental students (50%), 63 dental hygiene students (82%), 30 dental faculty members (26%), and 12 dental hygiene faculty members (52%) at the University of Michigan; 143 dental hygiene students in other programs (20%); and 95 members of the Michigan Dental Hygienists' Association (10%). The results showed that the dental students were less educated about PA 161 than the dental hygiene students, and the dental faculty members were less informed than the dental hygiene faculty members and dental hygienists. Responding dental hygiene faculty members and dental hygienists had more positive attitudes about PA 161 than did the students and dental faculty members. Most of the dental hygiene faculty members and dental hygienists knew a person providing services in a PA 161 program. Most dental hygiene students, faculty members, and dental hygienists wanted more education about PA 161. Overall, the better educated about the program the respondents were, the more positive their attitudes, and the more interested they were in learning more. PMID:27587574

  16. The future dental workforce?

    2009-02-28

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

    The use of materials to rehabilitate tooth structures is constantly changing. Over the past decade, newer material processing techniques and technologies have significantly improved the dependability and predictability of dental material for clinicians. The greatest obstacle, however, is in choosing the right combination for continued success. Finding predictable approaches for successful restorative procedures has been the goal of clinical and material scientists. This article provides a broad perspective on the advances made in various classes of dental restorative materials in terms of their functionality with respect to pit and fissure sealants, glass ionomers, and dental composites.

Among white patients, a 40 percent excess of treated psychiatric disorders was observed in the irradiated group, but there was no difference among blacks

  5. Prevalence of benign and malignant thyroid nodules in patients with previous history of radiotherapy for Tinea capitis in childhood (in khorosan province)

    International Nuclear Information System (INIS)

    Increased prevalence of thyroid cancer was noted in patients with previous history of radiotherapy of the head and neck region in childhood. According to previous research, radiotherapy for Ti nia capitis was using up to 30 years ago in Khorasan Province. This study tries to evaluate prevalence of benign and malignant thyroid nodules and detect and treat these patients earlier to prevent more complications and increased cost. Methods and patients: Using mass media, we recalled all patients with history of radiotherapy for Tinea capitis in childhood. A questionnaire was filled for each patient and thyroid examination, thyroid scan and thyroid sonography were performed. Fine needle aspiration biopsy (FNAB) was done if a thyroid nodule larger than 1 cm was palpable. Serum TSH was measured in all patients. Also thyroid surgery was recommended for all patients with thyroid nodules more than 1 cm. A control group was defined from a group of patients who referred for non thyroidal sonography to radiology department of Ghaem hospital. These patients also were evaluated by clinical examination and thyroid sonography. Results: We studied 180 patients with mean age of 47.7 years and 127 age and sex m etched controls. Thyroid nodules was palpated in 45.5% of patients and 7% of controls (P0.01). The mean largest diameter of nodules were 24.8 mm in patients and 10.8 mm in control group (P<0.001). 75% of patients were agreed with FNAB and 5% of them had suspicious cytology results. No suspicious or malignant results was noted in control group. Twenty seven patients (33.7%) were operated. Pathological results were benign in 89.9% and malignant in 1% of patients. His study showed that thyroid nodules and thyroid neo plasma were significantly more larger in the patients group. Thyroid neoplasm were more frequent in younger patients with latent thyroid (from radiotherapy) of less than 40 years, so aggressive evaluation is recommended in these group

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

    Full Text Available Introduction: The use of dental implants to restore missing teeth has become increasingly widespread over the past two decades. Dental MSCT plays an important role in the preoperative planning of dental implants because it provides accurate measurement of the width and depth of the edentulous ridge as well as the bone density. And postoperatively, dental MSCT images can show the failure of an endosseous implant to osseointegrate, improper placement of an implant, and violation of important structures. Aim of the work: Is to determine the success of dental implants following pre-operative multi-slice dental CT planning and for early detection of post-operative complications.Methods: The study included 25 patients that were divided in to 2 groups, Group I included 14 partially edentulous patients who underwent pre and post- operative dental MSCT, while group II included 11patients that already have dental implants and underwent post-operative dental MSCT using16-slice helical CT scanner.Results: There is highly significant (P < 0.001 relation between preoperative dental MSCT assessment and postoperative results and dental MSCT was very accurate in the evaluation of osseointegration and very sensitive in the detection of postoperative complications. Conclusion: Dental MSCT is a promising method that can be used as an imaging tool in the preoperative planning and postoperative assessment of dental implants

    2009-12-01

    As dental schools incorporate training in evidence-based dentistry (EBD) into their curricula, students must learn how to critically evaluate systematic reviews and meta-analyses. It is important that dental education in the United States support the American Dental Association's position statement on EBD, which defines "best evidence" as data obtained from all study designs. Given that much evidence is missing when EBD is derived from Cochrane Systematic Reviews' randomized clinical trials, we propose the creation of a dental practice network of U.S. dental schools. We developed an electronic clinical dentistry research database for EBD using Epi-Info (available at www.cdc.gov/epiinfo/downloads.htm). As a free, public use software, Epi-Info provides the foundation for the development of clinical research databases that can increase the research capacity through multisite studies designed to generate outcomes data on the effectiveness of dental treatment. The creation of a dental practice network of dental schools with their large number of patients would expand the research capacity for EBD practice and advance the EBD science regarding the effectiveness of dental treatment. The next step is to link clinical dental researchers/educators at multiple dental schools through a collaborative clinical research network, so that the findings can be applied to the EBD component of problem-based learning curricula of dental education.

    The Association of Dental Support Organizations is a recently formed association of 33 companies representing a range of management and support services for dental practices. These organizations do not engage in the practice of dentistry, although in some cases they operate as holding companies for practices that do, thus separating the legal responsibility of providing treatment from the management and flow of funds. This report summarizes some of the recent trends in oral health care and dentists' practice patterns that are prompting the increased prevalence of this model. The general functioning of the DSO model is described, including some common variations, and the core values of ADSO are featured. PMID:26455048

    Full Text Available Background. In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska’s Tribal Health Organizations (THO developed a new and diverse dental workforce model to address AI/AN oral health disparities. Objectives. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. Results. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Conclusions. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

    The diagnostic use of oral radiology is an essential part of daily dental practice. Due to the potentially harmful nature of ionising radiation, the clinical use of oral radiology in the Netherlands is framed by clinical practice guidelines and regulatory requirements. Undergraduate students receive intensive theoretical and practical training in practical and theoretical radiology, with the aim of obtaining the 'Eindtermen Stralingshygiëne voor Tandartsen en Orthodontisten'-certificate, which is required for legal permission to use oral radiology in dental practice. It is recommended that the curriculum be expanded to include the areas of knowledge required to qualify for the 'Eindtermen Stralingshygiëne voor het gebruik van CBCT-toestellen door tandartsen' (the certificate for the use of conebeam radiology by dentists). The general dental practitioner is faced with changing laws and regulations in all areas of practice. One of the most significant legal changes in the field of dental radiology was the introduction of the new radiation protection and safety rules in 2014. Moreover, a large group of dentists is also being confronted with the transition from conventional to digital images, with all its challenges and changes in everyday practice. PMID:27073811

  16. Ethics of dental health screening.

    Janakiram, Chandrashekar; Taha, Farheen

    2016-01-01

    Screening is the detection of disease at a point in its natural history when it is not yet symptomatic. In the natural history of dental caries, for example, the incipient lesions are at a reversible stage, which is a pre-symptomatic or an unrecognised symptomatic disease. Ideally, this is the stage during which screening should identify the risk of dental caries; however, presently, the so-called dental screening employed identifies the clinical cavitation of the tooth, which is very obvious to the individual. The individual already knows that he/she has dental caries and needs treatment, which the screening personnel (dental doctor) explains again during the screening procedure. Is it ethical to call such an event screening? The mushrooming of dental teaching hospitals has promoted regular screening of dental diseases among the communities and schoolchildren through their community dentistry-related activities. More often, it is a dental "check-up" that is carried out on the pretext of screening for dental diseases. Though the basic intention of this activity is to promote awareness of dental diseases and promote good health, there is also a hidden agenda to it. An artificial demand for dental care is created that is easily capitalised on by the dental teaching institutions to enhance its clinical activity. Dental screening is doing more harm than good as patients are made aware of the diseases for which they may not be able to afford treatment. This narrative review gives an account of the scientific evidence on screening for oral diseases, the current practices in screening and the ethical dilemmas of dental screening programmes.

    Full Text Available Folliculitis et perifolliculitis capitis abscedens et suffodiens is a rare disease of unknown etiology. It is a suppurative process that involves the scalp, eventually resulting in extensive scarring and irreversible alopecia. The condition is also known as ′acne necrotica miliaris′ or ′Proprionibacterium′ folliculitis. Most often the disease affects men of African-American or African-Caribbean descent between 20 and 40 years of age. The clinical picture is determined by fluctuating painful fistule-forming conglomerates of abscesses in the region of the occipital scalp. The cause of scalp folliculitis is not well understood. It is generally considered to be an inflammatory reaction to components of the hair follicle, particularly the micro-organisms. These include: bacteria (especially Propionibacterium acnes, but in severe cases, also Staphylococcus aureus, Yeasts (Malassezia species and mites (Demodex folliculorum. The initial histopathologic finding is an exclusively neutrophilic infiltration followed by a granulomatous infiltrate. The treatment of the disease is usually difficult and often disappointing. Successful treatment with isotretinoin 1 mg/kg body mass could be achieved only after regular systematic administration in the course of 3-4 months. Here we describe a patient with eruptive purulent form of the disease, which has been controlled with combination therapy: systemic antibiosis with metronidazole and clindamycin, dermatosurgical removal of single nodular formations, and isotretinoin 1 mg/kg body mass for 3-5 months.

    Dental erosion develops through chronic exposure to extrinsic/intrinsic acids with a low pH. Enamel erosion is characterized by a centripetal dissolution leaving a small demineralized zone behind. In contrast, erosive demineralization in dentin is more complex as the acid-induced mineral dissolution leads to the exposure of collagenous organic matrix, which hampers ion diffusion and, thus, reduces further progression of the lesion. Topical fluoridation inducing the formation of a protective l...

    2013-01-01

    One in four adults reports a clinically significant fear of dental injections, leading many to avoid dental care. While systematic desensitization is the most common therapeutic method for treating specific phobias such as fear of dental injections, lack of access to trained therapists, as well as dentists’ lack of training and time in providing such a therapy, means that most fearful individuals are not able to receive the therapy needed to be able to receive necessary dental treatment. Computer Assisted Relaxation Learning (CARL) is a self-paced computerized treatment based on systematic desensitization for dental injection fear. This multicenter, block-randomized, dentist-blind, parallel-group study conducted in 8 sites in the United States compared CARL with an informational pamphlet in reducing fear of dental injections. Participants completing CARL reported significantly greater reduction in self-reported general and injection-specific dental anxiety measures compared with control individuals (p < .001). Twice as many CARL participants (35.3%) as controls (17.6%) opted to receive a dental injection after the intervention, although this was not statistically significant. CARL, therefore, led to significant changes in self-reported fear in study participants, but no significant differences in the proportion of participants having a dental injection (ClinicalTrials.gov, NCT00609648).

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

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

  13. Comparison of thyroid examination, thyroid scanning and sonography in patients with previous history of radiotherapy of the head for Tinea Capitis

    International Nuclear Information System (INIS)

    Introduction: In spite of large number of studies regarding relation between thyroid cancer and childhood irradiation, controversy still exists in management of these patients. This study tries to find optimal method of thyroid evaluation in this group. Methods and patients: In a recall program using mass media in Khorasan, all patients with childhood irradiation were invited for thyroid evaluation. One hundred and eighty patients with previous history of radiation for Tinea Capitis were studied using thyroid examination, thyroid sonography and thyroid scintigraphy. FNAB was performed in all patients with palpable nodules and surgery was recommended. Results: Eighty two cases out of 179 patients (45.8%) had nodules in thyroid examination. The number were 85 from 166 (51.2%) in sonography and 75 from 165 (45.5 %) in thyroid scintigraphy. Using chi-square tests, no significant difference was noted in detection of thyroid nodules in different methods (p=0.78) as well as between the methods (p>0.5). Sonographically detected nodules which were not palpated or were not seen in scintigraphy, were < 10 mm in size in most of cases. FNAB were performed in 60 patients which revealed benign pathology in 89.9 %, inadequated in 5 % and suspicious for malignancy in other 5 % of cases. Also 27 patients underwent surgery and pathological studies showed 3 cases (11.1 %) of papillary carcinoma. Conclusion: This study revealed that sonography detects small nonpalpable nodules which are not clinically significant. Very high correlation between the results of thyroid examination and thyroid scintigraphy indicates adequacy of thyroid examination in these patients. we suggest to follow these patients with physical examination and FNAB and use thyroid scanning or sonography in doubtful cases only

    Head lice infestation (HLI) caused by Pediculus humanus capitis has been a public health problem worldwide. Specially designed combs are used to identify head lice, while anti-lice products are applied on the scalp for treatment. In the present study, we aimed to test whether combing only by precision detection comb (PDC) or metal pin comb (MPC) could be effective alternatives to the use of anti-lice products in children. A total of 560 children from two rural schools in Turkey were screened. In the PDC trial, children were combed every second day for 14 days, while in the MPC trial, combing was performed once in every four days for 15 days. Children were divided into two groups (dry combing and wet combing) for both trials and results were compared. The results showed no significant differences between dry and wet combing strategies for both combs for the removal of head lice (p > 0.05). The number of adult head lice declined significantly on each subsequent combing day in both approaches, except on day 15 in the MPC trial. In the end, no louse was found in 54.1 and 48.9% of children in the PDC and MPC trials, respectively. Since family members of infested children were not available, they were not checked for HLI. Four times combing within 2 weeks with MPC combs was found effective for both treatment of low HLI and prevention of heavy HLI. In conclusion, regular combing by special combs decreases HLI level in children and is safely applicable as long-term treatment. PMID:25604670

    The increasing complexity of the dental office environment influences productivity and workflow for dental clinicians. Advances in technology, and with it the range of products needed to provide services, have led to sprawl in operatory setups and the potential for awkward postures for dental clinicians during the delivery of oral health services. Although ergonomics often addresses the prevention of musculoskeletal disorders for specific populations of workers, concepts of workflow and productivity are integral to improved practice in work environments. This article provides suggestions for improving workflow and productivity for dental clinicians. The article applies ergonomic principles to dental practice issues such as equipment and supply management, office design, and workflow management. Implications for improved ergonomic processes and future research are explored. PMID:20448328

  1. Dental Forensics: Bitemark Analysis

    Directory of Open Access Journals (Sweden)

    Elza Ibrahim Auerkari

    2013-06-01

    Full Text Available Forensic odontology (dental forensics can provide useful evidence in both criminal and civil cases, and therefore remains a part of the wider discipline of forensic science. As an example from the toolbox of forensic odontology, the practice and experience on bitemark analysis is reviewed here in brief. The principle of using visible bitemarks in crime victims or in other objects as evidence is fundamentally based on the observation that the detailed pattern of dental imprints tend to be practically unique for each individual. Therefore, finding such an imprint as a bitemark can bear a strong testimony that it was produced by the individual that has the matching dental pattern. However, the comparison of the observed bitemark and the suspected set of teeth will necessarily require human interpretation, and this is not infallible. Both technical challenges in the bitemarks and human errors in the interpretation are possible. To minimise such errors and to maximise the value of bitemark analysis, dedicated procedures and protocols have been developed, and the personnel taking care of the analysis need to be properly trained. In principle the action within the discipline should be conducted as in evidence-based dentristy, i.e. accepted procedures should have known error rates. Because of the involvement of human interpretation, even personal performance statistics may be required from legal expert statements. The requirements have been introduced largely due to cases where false convictions based on bitemark analysishave been overturned after DNA analysis.DOI: 10.14693/jdi.v15i2.76

    International Nuclear Information System (INIS)

    Two main classes of material are involved, the glass-ionomer cements and the composite resins. This investigation describes the way they are bonded to the tooth and highlights their differences. Glass ionomers develop a zone of interaction with the tooth as they age which ultimately gives an extremely strong bond, and results in excellent retention rates. By contrast, bonding of composite resins is more complicated and possibly less effective, though these materials have better wear resistance and better aesthetics than glass ionomers. Assessment of bond durability is difficult. This is because a dental restorative can fail by a number of mechanisms apart from de bonding: for example, through wear or fracture

    This study assesses the pattern of employment of dental hygienists who qualified from the Liverpool Dental Hospital School of Dental Hygiene between 1977 and 1986. Of the 100 students who qualified during this period, 98 responded to a questionnaire. Seventy-seven per cent were employed as dental hygienists or dental health educators at the time of the survey, which took place between October 1987 and February 1988. The results show that after an initial slight under-employment, the majority quickly found as much work as they wanted and worked for an average of 2.24 practices each. The majority chose part-time employment and there was a steady decline in the number of sessions worked from the third year after qualifying. This decline was due to domestic commitments rather than dissatisfaction with the job. Only 4% stated they would definitely not return to work as a hygienist whilst a further 10% were uncertain.

The aim of this study was to specify the clinical and histological features of these BCC seen in 33 patients (1995 000). Twenty seven men and six women were diagnosed with BCC. The age of onset varied between 32 an 62 years. Radiotherapy was received between 5 and 17 years of age. The interval between irradiation and the onset of carcinoma varied between 21 and 51 years. Total number of lesions was 55. Forty percent of BCC occurred on the occipital area, the number varied from 1 to 5 and the size from 2 to 45 mm. Clinically, the nodular type was found in 51% of cases. Pigment was present in 64% of cases. Histological study showed a nodular aspect in 76% and pigmentation in 63% of cases. Nodular and pigmented type were the predominant BCC occurring after radiotherapy for tinea capitis in our series. In the literature, BCC are the most frequent carcinomas occurring after radiotherapy (70-100%). Pigmentation was not described in other series. The nodular histological form was the most frequent.

  12. Dental imaging characterization of micropigs

    International Nuclear Information System (INIS)

    Recently the micropig has been developed as human disease model. The dental and orofacial region of micropig is similar to that of humans, so it has been used for testing implant materials and techniques. The purpose of this study is on dental image at each age using radiography and computed tomography. Total twenty-two male micropigs, two or three animals of each 1, 3, 5, 7, 9, 12, 18 and 24 months old, were given radiographic examinations. After general anesthesia, extra- and intra-oral radiographic technique and computed tomographic scans were performed to assess the dental characterization of micropigs. The total deciduous dental formula comprised 28 teeth and was depicted as Di 3/3, Dc 1/1, Dp 3/3. The total permanent dental formula comprised 44 teeth and was depicted as I 3/3, C 1/1, P 4/4, M 3/3. Hypodontia of the first premolars was common in the micropig. The permanent teeth erupted from 3 to 24 month after birth. The sequence of eruption of the permanent teeth was M1, P1, I3, C, M2, I1 + P3 + P4, P2, I2, M3. Dental imaging enables visualization of the unerupted teeth and gives more information about the development of the teeth. The growth pattern of the teeth obtained through radiographic and computed tomographic examination provides basic data in the micropig as animal model for dental research

    Three hundred patients of chronic urticaria were screened for dental affections. Sixty two (20.66%) patients were detected to have dental caries. Among the control group which com-prised of 100 patients, 20% had dental caries. There was thus no increased incidence of dental caries among patients with urticaria. Only 2 patients had remission of urticaria following treat-ment of caries. Dental caries therefore is probably not a cause of chronic urticaria.

    International Nuclear Information System (INIS)

    Purpose: To demonstrate the usefulness of Dental-MRT for imaging of anatomic and pathologic conditions of the mandible and maxilla. Methods: Seven healthy volunteers, 5 patients with pulpitis, 9 patients with dentigerous cysts, 5 patients after tooth transplantation and 12 patients with atrophic mandibles were evaluated. Studies of the jaws using axial T1- and T2-weighted gradient echo and spin echo sequences in 2D and 3D technique have been to performed. The acquired images were reconstructed with a standard dental software package on a workstation as panoramic and cross sectional views of the mandible or maxilla. Results: The entire maxilla and mandibula, teeth, dental pulp and the content of the mandibular canal were well depicted. Patients with inflammatory disease of the pulp chamber demonstrate bone marrow edema in the periapical region. Dentigerous cysts and their relation to the surrounding structures are clearly shown. After contrast media application marked enhancement of the dental pulp can be found. Conclusion: Dental-MRT provides a valuable tool for visualization and detection of dental diseases. (orig.)

    Computerised tomography (CT) plays a key role in the pre-surgical evaluation of the alveolar process for titanium dental implants. The successful replacement of lost teeth by tissue integrated tooth root implants is a major advance in clinical dentistry. The paper will discuss briefly the history of osseointegration and how CT is now involved in helping the edentulous patient. CT is considered as a quick and convenient method of obtaining excellent anatomical information about the maxilla. Conventional tomography is difficult to obtain and does not provide valuable cross-sectional images. Exact height and width calculations can be made as well as screening out patients with advanced bone resorption. 3 refs. 6 figs

    Full Text Available AbstractBackground The Chronic Dental Disease Scheme (CDSS is the first public dental policy in Australia to attract Medicare benefits for dental services. Aims This study examines the utilisation of a new federal method of funding dental care in Australia and provides an insight into the implications of government dental programs. The program titled; Chronic Dental Disease Scheme, provided government-subsidised dental care for people suffering from a chronic medical condition. Method A retrospective analysis of activity data using the relevant item numbers were extracted from the open source Medicare Benefits Schedule database (MBS for years 2007-2009. Results During the study period, a total of approximately five million dental services were provided. There was a disproportionate use of services between jurisdictions. The highest proportion (66% of services was provided in the state of New South Wales (NSW with Victoria second (22%. The adjusted value of care provided as a proportion of comprehensive examinations ranged from $1937 in the northern territory (NT to $2900 in NSW. The value of care per dentist ranged from nearly $80 000 down to less than $1000 and the value of care per adult of the population ranged between $53 and $1 across Australia. The highest was always in NSW and the lowest always being the NT. Fixed prosthodontics (reconstruction accounted for the significant costs associated with the program. Conclusion The scheme has been utilised above its budget estimate with prosthodontics accounting for the majority of expenses. Treatment plans differed between jurisdictions. The increase in utilisation of the scheme was coincident with periods of increased in subsidy and remuneration and has been postulated to be a main driver for its utilisation rather than the improvement in chronic health.

    2015-06-01

    The application of surface topography measurement and characterization within dental materials science is highly active and rapidly developing, in line with many modern industries. Surface measurement and structuring is used extensively within oral and dental science to optimize the optical, tribological and biological performance of natural and biomimetic dental materials. Although there has historically been little standardization in the use and reporting of surface metrology instrumentation and software, the dental industry is beginning to adopt modern areal measurement and characterization techniques, especially as the dental industry is increasingly adopting digital impressioning techniques in order to leverage CAD/CAM technologies for the design and construction of dental restorations. As dental treatment becomes increasingly digitized and reliant on advanced technologies such as dental implants, wider adoption of standardized surface topography and characterization techniques will become evermore essential. The dental research community welcomes the advances that are being made in surface topography measurement science towards realizing this ultimate goal.

    2007-01-01

    Full Text Available Abstract The paradigmatic shift to evidence-based dentistry (EBD that relates to occlusal therapy, selective occlusal adjustment (OA and stabilization splints therapy (SS for TMDs has had an unfavourable impact on the teaching of many of the important aspects of occlusion needed in dental practice. The teaching of OA systematically in dental schools has been nearly abandoned because of the belief that OA is an irreversible procedure and gives the impression that it is without merit elsewhere in the management of occlusion. However, a particular dose of knowledge and practice of occlusion that is necessary for all aspects of dental care should be taught systematically in dental schools. The uses and misuses of OA and SS and their limitations should be emphasized because of their importance to bring clinical reality into the dental curriculum. Thus, and irrespective of EBD induced contradictions, OA and SS should still have a significant place in systematically teaching of occlusal therapy. However, there are many more aspects of the management of occlusion that should to be considered. Hopefully, because of their importance, other aspects of the management of occlusion will once again become a significant part of the dental curriculum.

    The purpose of this study was to assess the feasibility of dental ultrasound with conventional sonographic equipment. The teeth of three adult volunteers who had cone beam CT examinations performed previously with clinical indications and one extracted tooth were examined using linear and compact (hockey stick) sonographic probes. The sonographic images were compared with cone beam CT images reconstructed accordingly. Dental pulp spaces were demonstrated in all teeth not covered with prosthetic crowns. The dentin and pulp were best visualized at the level of the neck of the teeth. The dentin was hypoechoic, and the superficial layer comprising the cementum and the pulp spaces were hyperechoic. Dental ultrasound is feasible with general purpose sonographic machines. The buccal surfaces of all teeth are accessible with a compact (hockey stick) probe. Visualization and differentiation of dental pulp spaces, dentin and the superficial layer comprising cementum is possible in the portions of teeth not covered by the alveolar bone or prosthetic crowns. The dental pulp spaces are best seen at the level of the tooth neck. Pulp and endodontic fillings can be distinguished on ultrasound. PMID:24170803

    Full Text Available The central idea of the Brazilian health system is to prevent the establishment of disease or detect it as early as possible. Prevention and treatment of dental caries are related to behavioral factors, including dietary and oral hygiene habits, which are related to many chronic diseases. Dental health promotion therefore should be fully integrated into broadly based health-promoting strategies and actions such as food and health policies, and general hygiene (including oral hygiene, among others. For decades, a linear relationship between sugar consumption and caries has been observed. Recent data has indicated that this relationship is not as strong as it used to be before the widespread use of fluoride. However, diet is still a key factor acting in the carious process. Oral hygiene is a major aspect when it comes to caries, since dental biofilm is its etiological factor. Oral hygiene procedures are effective in controlling dental caries, especially if plaque removal is performed adequately and associated with fluoride. An alternative to a more efficient biofilm control in occlusal areas is the use of dental sealants, which are only indicated for caries-active individuals. If a cavity is formed as a consequence of the metabolic activity of the biofilm, a restorative material or a sealant can be placed to block access of the biofilm to the oral environment in order to prevent caries progress. The prevention of dental caries based on common risk-factor strategies (diet and hygiene should be supplemented by more disease-specific policies such as rational use of fluoride, and evidence-based dental health care.

    Full Text Available Periodontal disease is among the most prevalent canine dis-eases affecting over 75% of dogs. Strengthening of the human-animal bond and the increasing education of the aver-age pet owner, have fostered a heightened awareness of periodontal care in dogs and cats. Industry support has further assisted the small animal veterinarian in providing quality dental treatments and prevention. As recently as the 1990’s, veterinary curriculums contained little or no dental training. That trend is changing as nearly every one of the 28 US Colleges of Veterinary Medicine offers some level of small animal dentistry during the four-year curriculum. Primary areas of focus are on client education, the treatment of periodontal disease, dental prophylaxis, dental radiology, endodontics, exodontics and pain control. Students receive instruction in dental anatomy during their di-dactic curriculum and later experience clinical cases. Graduate DVMs can attend a variety of continuing education courses and even choose to specialize in veterinary dentistry in both small animals and horses. Through the efforts of organizations such as the American Veterinary Dental So-ciety, The American Veterinary Dental College and The Academy of Veterinary Dentistry, many veterinarians have been able to advance their skills in dentistry and improve animal welfare. Increasing ex-pectations of the pet-owning public coupled with the recent advancements of training opportunities available for vete-rinary students, graduate DVMs and certified veterinary technicians make veterinary dentistry an emerging practice-builder among the most successful small animal hospitals.

    A wide variety of restoration materials for prosthetic odontology is now available to the dental surgeon, either of the covalent type (acrylic resins), metallic (alloys), ionic (porcelains), or a combination of them, as in the so-called composites, such as the composite resins, or as ceramics-metals mixtures. An example of the latter is a product called Miracle-Mix, a glass ionomere cement reinforced with an amalgam alloy. In those cases where the blend is done by a synterization process, the material is called Cermet. The above-listed alternatives clearly evidence day-to-day advances in odontology, with researchers and manufacturers engaged the world over in improving existing products or developing new ones to enrich the dentist's armamentarium. As a side effect of this constant renewal, those dentists who have failed to update their knowledge fall behind in their practice as they persist in using products they have known for years, and may be deceived by advertisements of too-often unreliable products. It is, therefore, important to be aware of available products and their latest improvements. PMID:2132464

    Full Text Available In the present study we aimed to optimize the thermal imaging method for evaluation of skin patch test reactions in dental clinical allergology. A total of 30 patients without a history of allergic diseases were included in the study - 12 men and 18 women, age 21 - 32 years. Skin patch testing was performed with a set of 20 standardized allergens. The thermographic investigations were performed with the FlirT620 infrared camera with a temperature resolution of 0,06°C. Thermograms were analysed using the Flir Reporter Professional software 2013. The statistical analysis of the results revealed an average correlation between the clinical evaluation of the results according to the cheme of ICDRG and the thermal image diagnostic (rphi = 0.538, p = 0.001. Absolute matching of clinical and thermal image results was observed only for the negative ones. For the clinically positive skin patch results matching with thermal image method was observed in 60.7% of the cases. Optimization of thermal imaging as a method for evaluation of skin patch test results could serve as a safe, accurate and non-invasive method, especially to distinguish weak (+, doubtful and irritant reactions, although not standardized criteria to distinguish these reactions have been elaborated yet. Crucial factor for the accurate interpretation of results is the precise diagnosing performed by well-trained physicians in this area, with clinical relevance, to minimize the role of subjective factors.

  2. Dental care utilization over time.

    Beazoglou, T; Brown, L J; Heffley, D

    1993-12-01

    Between 1950 and 1978, per capita real dental expenditures in the U.S. grew at an average annual rate of 3.33%. Between 1978 and 1989 there was virtually no net growth in this measure of dental care utilization. This sharp curtailment of utilization growth has promoted debate about the sources of this change. Possible explanations include, among others, a reduction in dental disease due to increased exposure to fluoridation, the substitution of noncaloric sweeteners for refined sugar, preventive dentistry, , improved oral health habits, an increase in the net price of dental services, and the cost-containment efforts of insurers and employers. Changes have occurred in all of these variables, but little has done to isolate and quantify the individual effects. This decomposition is difficult, in part, because of the lack of an established model for time-series analysis of dental care utilization. A model of dental care demand, incorporating economic factors (out-of-pocket or net dental prices, per capita income, and nondental prices) as well as dietary factors (refined sugar consumption, noncaloric sweeteners, and exposure to fluoridated water), is combined with a simple model of dental care supply within an equilibrium framework. A two-stage estimation procedure is applied, using U.S. aggregate time-series data for the period 1950-89. Results show that economic and dietary factors are significantly related to changes in utilization. Net price and income elasticities of demand exhibit the expected signs and are compatible with estimates from cross-sectional studies. Decreases in cane and beet sugar consumption, facilitated by the increase in the use of noncaloric sweeteners, are associated with reductions in utilization. Fluoridation appears to be weakly but positively related to utilization. There also appears to have been a significant structural shift in demand since 1978. Overall goodness-of-fit is strong and the model accurately tracks the 1978-89 flattening of

    Objective To undertake a detailed educational evaluation into dental students' experience of the concept of belongingness and their development as 'safe beginners' on an outreach placement at the University of Portsmouth Dental Academy (UPDA).Method The participants were asked two questions: Did you feel belongingness at UPDA?; and When in your year rotation did you feel this? They completed the educational evaluation anonymously in their last week of attendance. The quantitative data was handled with descriptive statistics and the qualitative data was analysed for recurring themes.Results A 95% response rate was achieved. Eighty six percent of respondents strongly agreed to feeling belongingness and 56% felt it after their first two weeks. Four themes were identified: 'Interaction with the preexisting people environment' (1a. Initial welcoming and warmth 1b. Continued interest in me as an individual); 'Developing collegiality' (2a. My group of fellow students 2b. Working with the dental team as a dentist 2c. The team of everyone at UPDA); 'In the clinical environment' (3a. Being a dentist with responsibility and respect 3b. The physical environment 3c. Becoming a reflective independent practitioner); and 'Leadership'.Conclusion Belongingness in dental education should be defined as:- a deeply personal and contextually mediated experience in which a student becomes an essential and respected part of the dental educational environment where all are accepted and equally valued by each other and which allows each individual student to develop autonomy, self-reflection and self-actualisation as a clinician.

    2016-02-01

    As a highly prevalent multifactorial disease, dental caries afflicts a large proportion of the world's population. As teeth are constantly bathed in saliva, the constituents and properties of this oral fluid play an essential role in the occurrence and progression of dental caries. Various inorganic (water and electrolytes) and organic (proteins and peptides) components may protect teeth from dental caries. This occurs via several functions, such as clearance of food debris and sugar, aggregation and elimination of microorganisms, buffering actions to neutralize acid, maintaining supersaturation with respect to tooth mineral, participation in formation of the acquired pellicle and antimicrobial defense. Modest evidence is available on the associations between dental caries and several salivary parameters, including flow rate, buffering capacity and abundance of mutans streptococci. Despite some controversial findings, the main body of the literature supports an elevated caries prevalence and/or incidence among people with a pathologically low saliva flow rate, compromised buffering capacity and early colonization or high titer of mutans streptococci in saliva. The evidence remains weak and/or inconsistent on the association between dental caries and other saliva parameters, such as other possible cariogenic species (Lactobacillus spp., Streptococcus sanguis group, Streptococcus salivarius, Actinomyces spp. and Candida albicans), diversity of saliva microbiomes, inorganic and organic constituents (electrolytes, immunoglobulins, other proteins and peptides) and some functional properties (sugar clearance rate, etc.). The complex interactions between salivary components and functions suggest that saliva has to be considered in its entirety to account for its total effects on teeth. PMID:26662487

    This case report reviews the variability of dental eruption and the possible sequelae. Dental eruption of the permanent teeth in cleft palate children may be variable, with delayed eruption the most common phenomenon. A case of premature dental eruption of a maxillary left first premolar is demonstrated, however, in a five-year-old male. This localized premature dental eruption anomaly was attributed to early extraction of the primary dentition, due to caries.

    Australia has a complex history of providing public dental services to its communities. From the early days of Colonial settlement, the provision of dental care to the Australian public has largely been driven and influenced by organized groups and associations of dentists. The Constitution of Australia, under Section 51 xxiii A, allows for the Commonwealth to provide for medical and dental services. Unlike the United Kingdom, however, dental services have not been embedded into a universal national health service agenda. In 1974, that the Australian Government through the Australian School Dental Program provided the first funding and national direction for public dental services - and that, limited to children. The Commonwealth Dental Health Program 1993-1997 was the second national endeavor to provide public dental services, this time to financially disadvantaged adults. Since that time, public dental service responsibility has been shuttled between States/Territories and the Commonwealth. A new paradigm for public dental services in Australia requires strong Commonwealth leadership, as well as the commitment of State and Territories and the organized dental profession. The National Health and Hospitals Reform Commission provided the most recent scenario for a radical change in mission. This paper canvases the competing roles of strategic, functional, and structural issues in relationship to social network and policy issues, which must be recognized if Australians truly seek to reform public dental services.

  10. Caries detection in dental radiographs

    International Nuclear Information System (INIS)

    Caries, or the decay of teeth are difficult to automatically detect in dental radiographs because of the small area of the image that is occupied by the decay. Images of dental radiographs has distinct regions of homogeneous gray levels, and therefore naturally lead to a segmentation based automatic caries detection algorithm. This paper describes a method for caries detection based on a multiclass, area independent thresholding and segmenting scheme. This multiclass thresholding algorithm is an extension of the uniform error threshold, an area independent, distribution free thresholding method used for images of only two classes of objects. The authors first consider the problem of caries detection and the image features that characterize the presence of caries. Next, the uniform error threshold is reviewed, and the general multiclass uniform error threshold algorithm is presented. This algorithm is used to automatically detect caries in dental radiographs

    Mobley, Connie C

    2003-04-01

    Promotion of sound dietary practices is an essential component of caries management, along with fluoride exposure and oral hygiene practices. Scientific discoveries have lead to better understanding of the caries process, the ever-expanding food supply, and the interaction between the two. Fermentable carbohydrates interact dynamically with oral bacteria and saliva, and these foods will continue to be a major part of a healthful diet. Dental health professionals can serve their patients and the public by providing comprehensive oral health care and by promoting lifestyle behaviors to improve oral and general health within the time constraints of their practice. Dietary advice given should not contradict general health principles when providing practical guidance to reduce caries risk. The following principles should guide messages: * Encourage balanced diets based on moderation and variety as depicted by the Food Guide Pyramid and the Dietary Guidelines for Americans to provide a sound approach. Avoid references to "bad" foods and focus on "good" diets that include a variety of foods. * Give examples of how combining and sequencing foods can enhance mastication, saliva production, and oral clearance at each eating occasion. Combining dairy foods with sugary foods, raw foods with cooked, and protein-rich foods with acidogenic foods are all good examples. Suggest that eating and drinking be followed by cariostatic foods such as xylitol chewing gum. * Drink water to satisfy thirst and hydration needs as often as possible. Restrict consumption of sweetened beverages to meal and snack times when they can be combined with other cariostatic foods. * When a patient reports excessive dietary intake of a fermentable carbohydrate to the point of displacing other important foods in the diet, identify alternatives that will help the patient maintain or achieve a healthy body weight, oral health status, and a nutrient-dense intake.

  12. Low-dose dental CT

    International Nuclear Information System (INIS)

    Purpose: The intention of this study was to reduce patient dose during dental CT in the planning for osseointegrated implants. Methods and Materials: Dental CTs were performed with a spiral CT (Somatom Plus 4, Siemens) and a dental software package. Use of the usual dental CT technique (120 kVp; 165 mA, 1 s rotation time, 165 mAs; pitch factor 1) was compared with a new protocol (120 kVp; 50 mA; 0.7 s rotation time; 35 mAs; pitch factor 2) which delivered the best image quality at the lowest possible radiation dose, as tested in a preceding study. Image quality was analysed using a human anatomic head preparation. Four radiologists analysed the images independently. A Wilcoxon rank pair-test was used for statistic evaluation. The doses to the thyroid gland, the active bone marrow, the salivary glands, and the eye lens were determined in a tissue-equivalent phantom (Alderson-Rando Phantom) with lithium fluoride thermoluminescent dosimeters at the appropriate locations. Results: By mAs reduction from 165 to 35 and using a pitch factor of 2, the radiation dose could be reduced by a factor of nine (max.) (e.g., the bone marrow dose could be reduced from 23.6 mSv to 2.9 mSv, eye lens from 0.5 mSv to 0.3 mSv, thyroid gland from 2.5 mSv to 0.5 mSv, parotid glands from 2.3 mSv to 0.4 mSv). The dose reduction did not lead to an actual loss of image quality or diagnostic information. Conclusion: A considerable dose reduction without loss of diagnostic information is achievable in dental CT. Dosereducing examination protocols like the one presented may further expand the use of preoperative dental CT. (orig.)

  13. Patient dose in dental radiology

    International Nuclear Information System (INIS)

    September 1994 sees the publication of guidelines on radiology standards for primary dental care, a report by a joint Working Party of the Royal College of Radiologists (RCR) and NRPB. Central to these guidelines is the potential to reduce collective dose to patients and to improve the diagnostic quality of radiographs. This article presents the basis for the derivation of the collective dose to patients from dental radiology and identifies the amount by which the annual collective dose of some 170 man Sv can be reduced. The guidelines are described elsewhere in this bulletin. (Author)

    1999-12-01

    Until recently, conventional dental radiology was performed by dentists and orofacial surgeons. Due to the rapid development of radiological technique, the demand of radiological advice is increasing. The radiologists see more and more dental patients in their daily routine. The aim of this article is to give an overview on established dental radiology and a glimpse into the future. Conventional dental radiology and digital radiography are presently in use. Intraoral technique comprises dental films, bite-wing views and occlusal radiographs. Panoramic views and cephalometric radiographs are done with extraoral technique. Digital radiography lacks all processes in behalf of film development. It leads to dose reduction and enables image manipulation. PMID:10643025

    2011-06-01

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

  18. Radiographic signs and diagnosis of dental disease

    International Nuclear Information System (INIS)

    Dental radiographs are critical for the complete assessment and treatment of dental diseases. Dental radiography is commonly used to evaluate congenital dental defects, periodontal disease, orthodontic manipulations, oral tumors, endodontic treatments, oral trauma, and any situation where an abnormality is suspected. Although standard radiographic equipment and film can be used to produce dental radiographs, dental X-ray equipment and film provide superior quality images and greater convenience of animal patient positioning. An understanding of normal dental radiographic anatomy is important when interpreting dental radiographs. Stage III periodontitis is the earliest stage of periodontal disease at which radiographic abnormalities become apparent. Bone loss associated with periodontal disease can be classified as either horizontal or vertical. Periapical radiolucencies can represent granulomas, cysts, or abscesses, whereas periapical radiodensities may represent sclerotic bone or condensing osteitis. Lytic lesions of the bone of the jaw often represent oral neoplasms. Neoplasms also can displace or disrupt teeth in the dental arch. Resorptive lesions can be external or internal and appear as radiolucent areas involving the external surface of the root or the pulp cavity, respectively. Feline dental resorptive lesions, also known as odontoclastic resorptions, are a specific form of dental resorptive lesions unique to cats

    The incorporation of web-based learning into the dental curriculum has been consistently recommended in the literature on reform in dental education. There has been growing support for web-based learning in dental and dental hygiene education as demonstrated by deans' identifying this as a planned curricular innovation. The purpose of our study was to explore characteristics of e-courses that may serve to increase adoption among dental and dental hygiene faculty members. Eight ninety-minute focus groups (three dental; five dental hygiene) were conducted with dental (n=27) and dental hygiene (n=23) faculty members from six academic institutions. The resulting data were analyzed to identify two overarching themes and associated subthemes with regard to benefits and barriers influencing adoption of e-courses. A working conceptual framework, based on the Diffusion of Innovations, was developed from these themes to understand the characteristics that may influence the rate of adoption of e-courses among dental and dental hygiene faculty members. Analysis of the data revealed four main adoption barriers: 1) low perceived relative advantage to faculty members; 2) low compatibility with current curriculum; 3) high perceived time commitment; and 4) complexity of e-course development. This exploratory assessment identifies leverage points for facilitating the adoption and sustainability of e-courses in dental and dental hygiene education. PMID:21546592

  2. Radiation Protection in Dental Radiology

    International Nuclear Information System (INIS)

    Dentists undertake large numbers of diagnostic X ray examinations, but the generally accepted view is that radiation doses are low. Nonetheless, most dental radiology is performed outside radiology departments in independent practices, where self-referral is normal, paediatric patients form a large proportion of those exposed and quality assurance procedures may be lacking. While dental radiology encompasses a small range of techniques, the recent introduction of cone beam computed tomography (CBCT) promises to increase collective doses attributable to dental radiology in the future. While effective doses in well controlled research studies are quite low, dose audits suggest that the ‘real world’ situation is not so straightforward. In terms of justification, dentists are influenced in their use of diagnostic X rays by non-clinical factors. Referral criteria are available, but evidence for compliance is low. In terms of optimization, newer equipment and modified techniques should lead to lower doses, but their adoption is slow. There are particular optimization issues with CBCT, where some equipment gives little scope for exposure adjustment. The difficult challenges of radiation protection in dental radiology require efforts in education of dentists and increased awareness of evidence based guidelines, including audit of compliance with good practice. Regular dose audits and the setting of diagnostic reference levels are valuable tools, as long as they are followed by individualized feedback to dentists on optimization strategies. (author)

  6. Room design in dental radiology

    International Nuclear Information System (INIS)

    Radiography and radiographic examination of the patient form most valuable diagnostic tool in providing comprehensive dental care. The safe and effective use of the X-ray equipment is important for the protection of the patient, other members of the public and all members of the dental team. For patients, the risk that is associated with exposure to X-rays must always be weighed against the clinical benefit of an accurate diagnosis. The risks associated with the exposure to the X-rays during the radiographic examination of the patient must be minimised by meticulously adhering to good practice and thus carefully managing the use of dental radiological procedures. The dentist or the personnel who is the license holder for the X-ray equipment is ultimately responsible for the radiation safety at the workplace. One important method in limiting the possible risk of radiation exposure at workplace is the correct design of an X-ray room. This paper is aimed at discussing the guidelines and recommendations on X-ray room designs in dental radiology in order to facilitate radiation control and safe working conditions for radiation workers as well as the public.

    Full Text Available Globalization including General Agreement on Trade in Services (GATS and Asia Fair Trade Agreement (AFTA are a new free trade system. In globalization era, there will be an intense and free competition in looking for jobs throughout the world. This new system will affect the health services system in which health services tend to follow an industrial model. Meaning that dentistry or dental health services tend to be part of a business system, and this system has caused controversy among the community and the profession itself. The results of the discussion revealed that professional and business of dentistry is compatible and complementary. The tendency of increasing number of legal form of practice (group and a professional corporation and the worldwide advertisement of these practices supported the premise that delivering dental practice tends to follow the industrial model. Dentists should not only more focus on achieving financial success in running the business of practice but profession should have the most concern for the people who seek their services. Delivering quality of dental care depends on the high skill of the dentist and on the satisfactory income for the survival of the practice in the long run, and this make the practice will be viewed by the public and profession as being appropriate and of high quality. Facing the globalization, besides possessing high clinical skill, dentists must have a firm understanding of management concepts and apply them in their practice. In conclusion: The profession and the business of dentistry are compatible and complementary. The delivery of the dental services tends to follow the industrial model, which is a current reality. Dentist should concern more on the delivering high quality of dental services, not only focus on the business of the practice, although the satisfactory income is important for the survival growth of the practice in the long run.

    The thesis included five methodological studies and one caries epidemiological investigation, the general aim being to study how to measure and report dental health, time for dental care, treatment panorama, and dental care outcomes, within a Public Dental Service organization. The specific aims were to monitor dental clinic activities using a time study method, to apply time study results of a dental health-related patient group system for the 3-19 year age groups, and to compare time study results with corresponding results from computerized systems used for reporting dental care. Other specific aims were to compare longitudinal caries index data results between cohort and cross-sectional samples, to analyse caries index for extreme caries groups among adolescents leaving organized dental care, and--using time series methods--to analyse dental health development of the 15-19 year age groups. Results from the time studies portrayed the dental clinic as a working unit, showed that reported values can represent dental care only for intervention procedures, and indicated that clinic patterns were not adapted to the health situation of the patient groups. Longitudinal cohort attempts gave different values from those of the cross-sectional year classes, which should be the primary focus when presenting caries index mean values in dental health reviews. Caries-free groups from 15 to 19 years of age seem to be stable in their caries development in about 60%-80% of cases; while the 20% groups with the highest index values accounted for about 80% of all approximal lesions. In times of major economic adjustment, dental health for adolescents in Göteborg was an example of sustainable dental health development. A model system for monitoring, analysing, and reporting dental health and dental care outcomes within a dental care-giving organization calls for several conditions, for example, a dental health-related patient group system, and a rationale for the choice of dental

    Dental services for elderly patients are characterized by a series of particularities related to the vulnerability of this age group, which is affected by various co morbidities, and the diminished physical, cognitive and financial capacities. Finding ways to keep elderly patients coming to a dental office is possible by improving the dentist-patient relationship and implicitly the quality of care by increasing the self-esteem of the elderly and their place in society, by increasing the role of oral health in the quality of life, and here we refer to the pleasure of eating, the pleasant physical aspect and normal diction. The present paper presents the psychological aspects that interfere in the communication process between the dentist and the elderly patient and the changes motivation undergoes when people are in pain. These data can sometimes change the reticent attitude of the dentist towards the elderly patient which is often considered to be a risk patient. PMID:24502052

  15. Dental Pulp Defence and Repair Mechanisms in Dental Caries

    Directory of Open Access Journals (Sweden)

    Jean-Christophe Farges

    2015-01-01

    Full Text Available Dental caries is a chronic infectious disease resulting from the penetration of oral bacteria into the enamel and dentin. Microorganisms subsequently trigger inflammatory responses in the dental pulp. These events can lead to pulp healing if the infection is not too severe following the removal of diseased enamel and dentin tissues and clinical restoration of the tooth. However, chronic inflammation often persists in the pulp despite treatment, inducing permanent loss of normal tissue and reducing innate repair capacities. For complete tooth healing the formation of a reactionary/reparative dentin barrier to distance and protect the pulp from infectious agents and restorative materials is required. Clinical and in vitro experimental data clearly indicate that dentin barrier formation only occurs when pulp inflammation and infection are minimised, thus enabling reestablishment of tissue homeostasis and health. Therefore, promoting the resolution of pulp inflammation may provide a valuable therapeutic opportunity to ensure the sustainability of dental treatments. This paper focusses on key cellular and molecular mechanisms involved in pulp responses to bacteria and in the pulpal transition between caries-induced inflammation and dentinogenic-based repair. We report, using selected examples, different strategies potentially used by odontoblasts and specialized immune cells to combat dentin-invading bacteria in vivo.

  16. Dental insurance, income and the use of dental care in Canada.

    Bhatti, Taimur; Rana, Zeeshan; Grootendorst, Paul

    2007-02-01

    Using recent Canadian health survey data, we investigated the effect of socioeconomic status on patients' use of dental services and dental insurance coverage. Our results point to an important socioeconomic gradient in the use of dental services. The probability of receiving any dental care over the course of a year increases markedly with dental insurance, household income, and level of education. Among those receiving at least some dental care, however, a person's general oral health--not financial factors--largely determined visit frequency. The insurance effect appears to operate through a reduction in price paid at point of service, not decisions by those with high anticipated need for dental care to selectively purchase insurance. Indeed, those with poorer self-assessed oral health, as well as those from Quebec (where dental benefits are subject to personal income tax) and those over 65 years of age (who have likely lost employer provided coverage) were less likely to be insured.

  17. Salivary gland doses from dental radiographic exposures

    International Nuclear Information System (INIS)

    Salivary gland doses incurred during dental radiography were measured by phantom dosimetry, and these dose data and data obtained during a two-week survey of Hiroshima and Nagasaki dental hospitals and clinics were used to estimate the respective doses to members of the populations of the two cities. The results obtained were used to supplement previously determined doses to the thyroid gland, lens, and pituitary gland from dental radiography. No significant differences in doses were observed by age, sex or city. Doses to the salivary glands during dental radiography are probably not sufficiently large to cause bias in assessments of atomic bomb survivors for late radiation effects. However, the steadily increasing use of dental radiography underscores the need for continued monitoring of dental radiography doses in the interests of these assessments. (author)

  5. Dental X-ray apparatus

    International Nuclear Information System (INIS)

    Intra-oral dental X-ray apparatus for panoramic dental radiography is described in detail. It comprises an electron gun having an elongated tubular target carrier extending into the patient's mouth. The carrier supports an inclined target for direction of an X-ray pattern towards a film positioned externally of the patient's mouth. Image definition is improved by a focusing anode which focuses the electron beam into a sharp spot (0.05 to 0.10 mm diameter) on the target. The potential on the focusing anode is adjustable to vary the size of the spot. An X-ray transmitting ceramic (oxides of Be, Al and Si) window is positioned adjacent to the front face of the target. The electron beam can be magnetically deflected to change the X-ray beam direction. (author)

    International Nuclear Information System (INIS)

    This work is devoted to the optimization of fluorescence dental calculus diagnostics in optical spectrum. The optimal wavelengths for fluorescence excitation and registration are determined. Two spectral ranges 620 – 645 nm and 340 – 370 nm are the most convenient for supra- and subgingival calculus determination. The simple implementation of differential method free from the necessity of spectrometer using was investigated. Calculus detection reliability in the case of simple implementation is higher than in the case of spectra analysis at optimal wavelengths. The use of modulated excitation light and narrowband detection of informative signal allows us to decrease essentially its diagnostic intensity even in comparison with intensity of the low level laser dental therapy

    Full Text Available The term "work-related musculoskeletal disorders (WMSDs," refers to musculoskeletal disorders to which the work environment contributes significantly, or to musculoskeletal disorders that are made worse or longer lasting by work conditions or workplace risk factors. In recent years, there has been an increase in reporting WMSDs for dental persons. Risk factors of WMSDs with specific reference to dentistry include - stress, poor flexibility, improper positioning, infrequent breaks, repetitive movements, weak postural muscles, prolonged awkward postures and improper adjustment of equipment. Ergonomics is the science of designing jobs, equipment and workplaces to fit workers. Proper ergonomic design is necessary to prevent repetitive strain injuries, which can develop over time and can lead to long-term disability. In this article, 20 strategies to prevent WMSDs in the dental operatory are discussed.

    The elimination of the extreme fear reported by dental phobic patients traditionally involves psychologic interventions such as systematic desensitization. Observations resulting from a conscious sedation approach, as outlined in two case histories, suggest that a desensitization phenomena is occurring. This pharmacologic desensitization appears to mimic elements of systematic desensitization. Optimal management of fearful patients may sometimes require conjunctive support from both dental behavioral scientists and dental anesthesiologists. PMID:1982984

    1994-12-01

    The cost of dental services is related to their productivity. The purpose of the study was to identify factors influencing productivity, measured as time spent providing dental care per child under care, per year, in public dental clinics. The time was expected to vary with characteristics of the patients, the personnel and the clinics. Time spent by dentists and dental hygienists delivering dental care for children aged three to 18 years was obtained from 137 public dental clinics. The data showed substantial variation in productivity between clinics. Multiple regression analysis revealed that the time spent per child was associated with interval between examinations, proportion of male dentists, ratio of dental assistants to dentists, proportion of child treatment time given by dental hygienists and proportion of all treatment time spent on child patients. These variables explained 43 per cent of the variance in the total time spent by dentists and hygienists and 41 per cent of the variance in dentists' time. Individual dentists and hygienists may reduce the mean time spent per child by extending recall intervals. On an administrative level, dentists' time per child may be reduced by employing more dental assistants or dental hygienists and allowing dentists to treat patient groups other than children. It is concluded that productivity in dental care for children in the public dental services may be influenced in several ways, both by clinical and administrative decisions. PMID:7850642

El uso de pelo largo, así como la constitución lacia de éste, fueron las características más frecuentemente observadas en la población infestada, la cual estuvo conformada en su mayoría por individuos de raza blanca. Esta última observación podría estar relacionada más con la composición étnica de la población metropolitana que con un tropismo definido por los parásitos. Los índices de hacinamiento (Nº de personas por vivienda/ Nº de camas por vivienda más frecuentemente observados tuvieron valores entre 1.00 y 1.49, lo que refleja que una parte considerable de los niños infestados no vivían en condiciones de hacinamiento en sus viviendas. La presencia, de preescolares se evidenció en aproximadamente la mitad de la muestra estudiada, mientras que la utilización de guarderías sólo se vio en una minoría, por lo que estas características no se presentan como condicionantes importantes en la muestra poblacional estudiada. Los datos sugieren que la pediculosis capitis es uno de los problemas de salud pública más comunes en la niñez costarricense, el cual podría interferir con sus procesos de aprendizaje y lesionar su bienestar general.

  19. Dental Radiology: The Forgotten Problem?

    International Nuclear Information System (INIS)

    Radiology is an essential part of dental practice. Traditionally, this has relied upon a small number of simple radiographic techniques with a low level of associated radiation risk. High numbers of dental X ray examinations, the frequently young age of patients and the relatively low health benefits of dentistry mean that justification of examinations remains an important consideration. Most dentists work in independent practice and self-referral for imaging is normal. Non-clinical pressures, such as financial factors and defensive practice, may influence the use of X ray examinations. Referral criteria are available at national and international levels, but their evidence basis is variable and there is a lack of data for their impact on behaviour. Particular challenges in justification include frequency of X ray examinations, the use of routine panoramic radiography and cone beam CT. Improving the practice of justification in dental radiology will rely on the availability of high quality referral criteria, improved education of dentists and greater attention to audit of practice.

    Full Text Available The structural and functional fusion of the surface of the dental implant with the surrounding bone (osseointegration is crucial for the short and long term outcome of the device. In recent years, the enhancement of bone formation at the bone-implant interface has been achieved through the modulation of osteoblasts adhesion and spreading, induced by structural modifications of the implant surface, particularly at the nanoscale level. In this context, traditional chemical and physical processes find new applications to achieve the best dental implant technology. This review provides an overview of the most common manufacture techniques and the related cells-surface interactions and modulation. A Medline and a hand search were conducted to identify studies concerning nanostructuration of implant surface and their related biological interaction. In this paper, we stressed the importance of the modifications on dental implant surfaces at the nanometric level. Nowadays, there is still little evidence of the long-term benefits of nanofeatures, as the promising results achieved in vitro and in animals have still to be confirmed in humans. However, the increasing interest in nanotechnology is undoubted and more research is going to be published in the coming years.

  1. Bacterial sex in dental plaque

    Directory of Open Access Journals (Sweden)

    Ingar Olsen

    2013-06-01

    Full Text Available Genes are transferred between bacteria in dental plaque by transduction, conjugation, and transformation. Membrane vesicles can also provide a mechanism for horizontal gene transfer. DNA transfer is considered bacterial sex, but the transfer is not parallel to processes that we associate with sex in higher organisms. Several examples of bacterial gene transfer in the oral cavity are given in this review. How frequently this occurs in dental plaque is not clear, but evidence suggests that it affects a number of the major genera present. It has been estimated that new sequences in genomes established through horizontal gene transfer can constitute up to 30% of bacterial genomes. Gene transfer can be both inter- and intrageneric, and it can also affect transient organisms. The transferred DNA can be integrated or recombined in the recipient's chromosome or remain as an extrachromosomal inheritable element. This can make dental plaque a reservoir for antimicrobial resistance genes. The ability to transfer DNA is important for bacteria, making them better adapted to the harsh environment of the human mouth, and promoting their survival, virulence, and pathogenicity.

  4. New techniques in dental surgical CT

    International Nuclear Information System (INIS)

    This paper demonstrates how CT can be used with dental software to evaluate prosthetic failure and for planning dental implants when a stent is used. The Food and Drug Administration issued a safety alert for proplast-coated temporomandibular joint prostheses. Prosthetic failure occurs with migration, fragmentation, or bone erosion. Sagittal CT requiring a special head holder can instead be performed with reformatted sagittal images. The technique of dental implant CT changes when a dental stent is used to provide more accurate implant anchorage and planning. Images must be parallel to the occlusal plane. We will demonstrate these techniques and present their rationale

    2014-08-01

    Full Text Available Dental caries remains a significant public health problem and is considered pandemic worldwide. The prediction of dental caries based on profiling of microbial species involved in disease and equally important, the identification of species conferring dental health has proven more difficult than anticipated due to high interpersonal and geographical variability of dental plaque microbiota. We have used RNA-Seq to perform global gene expression analysis of dental plaque microbiota derived from 19 twin pairs that were either concordant (caries-active or caries-free or discordant for dental caries. The transcription profiling allowed us to define a functional core microbiota consisting of nearly 60 species. Similarities in gene expression patterns allowed a preliminary assessment of the relative contribution of human genetics, environmental factors and caries phenotype on the microbiota’s transcriptome. Correlation analysis of transcription allowed the identification of numerous functional networks, suggesting that inter-personal environmental variables may co-select for groups of genera and species. Analysis of functional role categories allowed the identification of dominant functions expressed by dental plaque biofilm communities, that highlight the biochemical priorities of dental plaque microbes to metabolize diverse sugars and cope with the acid and oxidative stress resulting from sugar fermentation. The wealth of data generated by deep sequencing of expressed transcripts enables a greatly expanded perspective concerning the functional expression of dental plaque microbiota.

    International Nuclear Information System (INIS)

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

    Dental coverage for adults is an elective benefit under Medicaid. As a result of budget constraints, California Medicaid eliminated its comprehensive adult dental coverage in July 2009. We examined the impact of this policy change on emergency department (ED) visits by Medicaid-enrolled adults for dental problems in the period 2006-11. We found that the policy change led to a significant and immediate increase in dental ED use, amounting to more than 1,800 additional dental ED visits per year. Young adults, members of racial/ethnic minority groups, and urban residents were disproportionately affected by the policy change. Average yearly costs associated with dental ED visits increased by 68 percent. The California experience provides evidence that eliminating Medicaid adult dental benefits shifts dental care to costly EDs that do not provide definitive dental care. The population affected by the Medicaid adult dental coverage policy is increasing as many states expand their Medicaid programs under the ACA. Hence, such evidence is critical to inform decisions regarding adult dental coverage for existing Medicaid enrollees and expansion populations. PMID:25941275

  6. Equity in dental care among Canadian households

    Directory of Open Access Journals (Sweden)

    2011-04-01

    Full Text Available Abstract Background Changes in third party financing, whether public or private, are linked to a household's ability to access dental care. By removing costs at point of purchase, changes in financing influence the need to reach into one's pocket, thus facilitating or limiting access. This study asks: How have historical changes in dental care financing influenced household out-of-pocket expenditures for dental care in Canada? Methods This is a mixed methods study, comprised of an historical review of Canada's dental care market and an econometric analysis of household out-of-pocket expenditures for dental care. Results We demonstrate that changes in financing have important implications for out-of-pocket expenditures: with more financing come drops in the amount a household has to spend, and with less financing come increases. Low- and middle-income households appear to be most sensitive to changes in financing. Conclusions Alleviating the price barrier to care is a fundamental part of improving equity in dental care in Canada. How people have historically spent money on dental care highlights important gaps in Canadian dental care policy.

  9. Normal range of Atlanta-dental interval

    International Nuclear Information System (INIS)

    The roentgenologic diagnosis of lateral subluxation of the atlanto-axial joint is very difficult because the only presentation is increase of the atlanto-dental interval. This study was carried out with 70 volunteers for normal value of atlanto-dental interval. We measured these intervals from lateral roentgenograms of cervical spine in neutral, flexion, and extension position of the neck. The results were as follows: 1. The mean value of atlanto-dental interval in all subjects was 1.54±0.52mm in neutral, 1.59±0.62mm in flexion, and 1.46±0.48mm in extension position. 2. After thirty years of age the atlanto-dental interval was getting narrower according to aging. 3. In neutral and flexion positions there is no difference in atlanto-dental intervals, but in extension position it was significantly narrowed.

    Lo, G L; Soh, G; Vignehsa, H; Chellappah, N K

    1991-01-01

    This study examines factors influencing the use of dental services by disabled children. A total of 322 disabled children, aged 6 to 18 years, attending nine special schools were randomly selected for a clinical examination. Their parents or guardians were interviewed to determine the child's pattern of dental service use, parental perception of the child's dental needs, and special problems encountered with seeking care. It was found that 68.3% of the children had never visited a dentist within the previous year. The most common reason given for no care was an assumption that "nothing was wrong." The results indicated a low rate of dental service use among the disabled children. A lack of parental dental awareness appeared to be a major contributory factor. PMID:1839867

  11. Dental enamel, fluorosis and amoxicillin

    Directory of Open Access Journals (Sweden)

    2012-06-01

    Full Text Available Introduction: Amoxicillin is one of the most used antibiotics among pediatric patients for the treatment of upper respiratory tract infections and specially for acute otitis media (AOM, a common diseases of infants and childhood. It has been speculated that the use of amoxicillin during early childhood could be associated with dental enamel fluorosis, also described in literature with the term Molar Incisor Hypomineralization (MIH, because they are generally situated in one or more 1st permanent molars and less frequently in the incisors. The effect of Amoxicillin seems to be independent of other risk factors such as fluoride intake, prematurity, hypoxia, hypocalcaemia, exposure to dioxins, chikenpox, otitis media, high fever and could have a significant impact on oral health for the wide use of this drug in that period of life. Objective: The aim of this work was to review the current literature about the association between amoxicillin and fluorosis. Methods and Results: A literature survey was done by applying the Medline database (Entrez PubMed; the Cochrane Library database of the Cochrane Collaboration (CENTRAL. The databases were searched using the following strategy and keywords: amoxicillin* AND (dental fluorosis* OR dental enamel* AND MIH*. After selecting the studies, only three relevant articles published between 1966 and 2011 were included in the review. Conclusion: The presence of several methodological issues does not allow to draw any evidence-based conclusions. No evidence of association was detected, therefore, there is a need of further well-designed studies to assess the scientific evidence of the relationship between amoxicillin and fluorosis and to restrict the prescription of this drug for recurrent upper respiratory tract infections especially acute otitis media (AOM during the first two years of life. When it is possible can be opportune to use an alternative antibiotic treatment.

  12. Dental underemployment: a study of uncontrolled dental manpower immigration.

    1993-08-01

    In the 1980s three studies were conducted in Israel utilising different methods of dental manpower evaluations. All identified a large future surplus of dentists. The current study re-evaluates the manpower supply and discusses possible solutions. A random sample of 800 dentists was approached by three mailings and a telephone call follow-up with a response of 49.7 per cent. Almost 90 per cent of dentists reported an undersupply of patients, with a mean working load of 26.3 hours/week, but being willing to add up to 3.4 working hours/week. The oversupply of dentists has been dramatically affected by the addition of almost 1000 dentists who emigrated to Israel in 1991-92. To prevent a significant unemployment rate among dentists and an uncontrolled free market, it is urgently suggested for the benefit of both provider and consumer that; the demand for services be increased and additional financing of dental care be made available, that the total number of dentists be decreased by various measures and that their geographical distribution be improved. If necessary limits should be placed on the number of practices or the number of patients permitted per practice. PMID:8276515

    Dental pulp stem cells were plated on two dentally relevant materials i.e. PMMA commonly used for denture and Titanium used for implants. In both cases, we probed for the role of surface interaction and substrate morphology. Different films of PMMA were spun cast directly onto Si wafers; PMMA fibers of different diameters were electro spun onto some of these substrates. Titanium metal was evaporated onto Si surfaces using an electron beam evaporator. In addition, on some surfaces, P4VP nanofibers were spun cast. DPSC were grown in alpha-MEM supplemented with 10% fetal bovine serum, 0.2mM L-ascorbic acid 2-phosphate, 2mm glutamine and 10mM beta-glycerol phosphate either with or without 10nM dexamethasone. After 21 days samples were examined using confocal microscopy of cells and by scanning electron microscopy (SEM) and Energy dispersive X-ray Analysis (EDAX). In the case of Titanium biomineralization was observed independent of dexamethasone, where the deposits were templated along the fibers. Minimal biomineralization was observed on flat Titanium and PMMA samples. Markers of osteogenesis and specific signaling pathways are being evaluated by RT-PCR, which are up regulated on each surface, to understand the fundamental manner in which surfaces interact with cell differentiation.

  14. Dental radiology in preventive dentistry

    International Nuclear Information System (INIS)

    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. (M.G.B.)

The filler compositions contain from about 3% by weight to about 10% by weight, based on the total filler composition, of the x-ray absorbing materials and the remainder being conventional particulate glass or silica, quarts or ceramic filler material. The radio opaque filler compositions are insoluble and non-leachable in alkaline, acidic or neutral aqueous environments, are essentially non-toxic, are either essentially colorless or translucent, and are compatible with acrylic monomers and other polymerizable binder systems

  16. Aspects pertinent to dental radiology

    International Nuclear Information System (INIS)

    The author puts forward the hypothesis that dental radiography is performed much more frequently and thus leads to a considerably greater number of exposures than generally assumed. Particular features of this branch of radiology are the low average age of patients examined and the mobility of the radiation sources. The method of panoramic sectional imaging, in which the dose to patients remains within acceptable limits, is used on an increasingly broader basis. This does, however, by no means obviate the need for an adequate radiological training of dentists and quality controls of the systems used. (MG)

  16. ORO dental complications of radiotherapy

    International Nuclear Information System (INIS)

    Radiation and radioactivity were discovered more than 100 years ago. Since then, radiation has become important in cancer treatment. Approximately one million people will develop invasive cancer each year. Of these, 40% will receive curative benefit from surgery, radiation, chemotherapy, or a combination modality. Normal body tissues vary in their response to radiation. As with tumors, normal tissues in which cells are quickly dividing may be affected. This causes some of the side effects of radiation treatment. Since radiation is a local treatment, side effects depend on the area of the body being treated. The early effects of radiation may be seen a few days or weeks after treatments have started and may go on for several weeks after treatments have ended. Other effects may not show up until months, or even years, later. As radiotherapy is a viable treatment modality for head and neck cancer, however a wide range of potentially debilitating dental complications may accompany this treatment. The orofacial tissues of dental significance that may be affected by head and neck radiotherapy are the salivary glands, mucous membranes, taste buds, bone and teeth. (author)

  4. What Will Dental Practice Be Like In 2025? Will You Help Dental Hypotheses Find Answers

    Directory of Open Access Journals (Sweden)

    Edward F. Rossomando

    2011-02-01

    Full Text Available As a result of the rapid acceptance of digital dental equipment, the dental office of 2011 looks very different from that of 1900. Despite these changes, the general dentist of 2011 performs almost the same functions as in 1900 namely the restoration of decayed teeth and the replacement of those lost due to disease. In addition to changes in technology, the last few decades of the 20th century ushered in a revolution in biology leading to the development of a genomic basis of dental disease and the development of bio-based diagnostics and therapeutics. In 2011 few if any of these bio-discoveries have changed dental practice but by 2025 we expect they will. In this editorial, Dental Hypotheses asks readers to “hypothesize” on what dental practice will be like in 2025.

  6. The relationship between diet and Dental Caries

    International Nuclear Information System (INIS)

    Dental caries is a disease of multifactorial etiology and results from a complex interaction between both cariogenic and protective influences acting on the teeth. Though diet plays a major role in the causation of dental caries it has been a common mistake to over-simplify the relationship. Dietary manipulation is also extremely difficult to achieve thus limiting its role in the prevention of caries. Accordingly, alternative preventive measures such as the use of fissure sealants and fluoride which enhance the resistance of the host to disease and are of proven efficacy are more likely to be successful in the control and prevention of dental caries.

    Fleischman, David; Davis, Richard M; Lee, Lyndon B

    2014-01-01

    Subcutaneous emphysema following a dental procedure is a relatively uncommon phenomenon that may produce a dramatic clinical presentation. The advent of high-powered dental equipment that uses directed and highly pressurized air has increased the risk of this complication, but few cases have been described in the ophthalmic literature. The authors present a case of subcutaneous periorbital emphysema in a young woman following a dental procedure. Aside from a temporary ptosis, there were no other ophthalmic complications. An attempt to decompress the air produced minimal relief. The condition resolved spontaneously within 1 week. PMID:24614564

    2016-07-01

    Over the last 20 years the majority of emerging infections which have spread rapidly across the globe have been respiratory infections that are spread via droplets, a trend which is likely to continue. Aerosol spray generation in the dental surgery has the potential to spread such infections to staff or other patients. Although the diseases may differ, some common approaches can reduce the risk of transmission. Dental professionals should be aware of areas affected by emerging infections, the incubation period and the recent travel history of patients. Elective dental care for those returning from areas affected by emerging infections should be delayed until the incubation period for the infection is over. PMID:27388077

  4. Postal audit in dental radiodiagnostics

    International Nuclear Information System (INIS)

    According to Czech laws dental intraoral X-ray machines are classified as simple sources of ionizing radiation. Consequently , their use is licensed on condition that an adequate quality assurance program is realized. In general, the programme is based on acceptance tests, status tests and constancy tests. The particular methods are specified in the recommendation [1] published by State Office for Nuclear Safety .Both the acceptance and status tests involve in situ measurements to control parameters of the X-ray machine and the developing process. Only persons who were licensed for such handling can do these measurements. The yearly status tests are very detailed and several years ' experience showed it might be advantageous to have a simpler method additionally available for purposes of the state supervision. Such a method is supposed as a postal audit. It should be simple enough to make the operation of the state supervision more effective but it also should provide sufficient information on radiation protection of the patients. Besides it should enable to prolong the period for the status tests ultimately .As for the postal audit, a small package containing a proper dosimetric set would be sent directly to the dentist who would treat it according to instructions. This paper describes such method that was developed in the National Radiation Protection Institute (NRPI) and results of pilot study that was carried out to test the method. The described method will be a helpful tool for the operation of the state supervision in the dental radiodiagnostics. The method will be implemented into the existing system of controls from 2002. Due to its simplicity and a quite rich content of information allows to check a big amount of the dental workplaces at once. It is supposed that one half of all Czech X-ray units will be checked in this way every year performed on state costs. It means 175 audits per month approximately. In this way, the operation of the quality assurance

    Dental pain is the most common symptom associated with a wide array of dental problems and significantly impacts the oral health-related quality of life. The epidemiology and prevalence of oral diseases that could lead to dental pain are diverse and indicate regional variations. Several researchers have dwelled into the neurobiology and pathophysiology of dental pain making the pain pathways more clear and deciphering the precise targets for the management of pain. Although a number of pharmacological drugs are available in the market, a significant percentage of the population in India prefers alternative herbal medication for relief from dental pain due to the side effects and interactions of pharmacological treatment. However, there is a void in dental literature pertaining to the use, benefits, and safety of the herbal medicines. Therefore, the present assessment has been penned down, focusing on the current multimodal approaches for treating dental pain, the current unmet need, and the role of herbal medication in India for the management of dental pain, with a discussion on novel herbal dental gel.

    Full Text Available Objective: Proper positioning of the child patient, can not only have positive ramifications for the operator′s posture, comfort, and career longevity - it can also lead to better treatment and increased productivity. The aim of the survey questionnaire was to assess the utilization, need, and attitude concerning dental chairs among pediatric dentist while working on and managing the child patient. Study Design: The questions were structured using adobe forms central online software, regarding the user-friendliness of pediatric dental chair vs. traditional adult dental chair available in the market. Results: Our result shows that out of 337 respondents, 79% worked on pediatric dental chair, whereas 21% had no experience of it. Of these 79% pediatric dentist, 48% preferred pediatric dental chair. But pediatric dental problem still has certain disadvantages like higher cost, leg space problem, lower availability, etc. Conclusion: During the research it was found that ergonomics and usability issues were the main problems. Thus, pediatric dental chair is not so popular in the current scenario. This study allowed for general ideas for the improvement of dental chairs and thus improved dental chair would fill the gap in the current scenario.

    This study examined the effect of dental hygiene preparation prior to entering dental school on dental school performance. Study participants included 203 female students who entered a public dental school from 1980-1989. Groups 1 and 2 had completed dental school prerequisites and a dental hygiene curriculum in a community college setting (n = 19) or university setting (n = 22) respectively, and Group 3 (n = 162) were traditional students with no dental hygiene education. Preadmission variables were predental science and non-science grade point averages (GPA) and Dental Admission Test (DAT) scores. Performance variables were GPA of years one and two of dental school and National Board scores (Part 1). Results showed that Group 2 hygienists had significantly lower predental science GPAs than Group 1 or 3 and significantly lower non-science GPAs than Group 3 (p difference was seen in first and second year GPAs or the National Board average. Adjusting performance scores to compensate for deficiencies in preadmission variables showed that Group 2 hygienists had significantly higher adjusted first-year GPAs and National Board averages than Group 3 (p < 0). Thus, hygienists performed as well as non-hygienists in spite of weaker admission credentials. PMID:8482741

  17. Dental X-ray apparatus

    International Nuclear Information System (INIS)

    Intra-oral dental X-ray apparatus for panoramic radiography is described in detail. It comprises a tubular target carrier supporting at its distal end a target with an inclined forward face. Image definition is improved by positioning in the path of the X-rays a window of X-ray transmitting ceramic material, e.g. 90% oxide of Be, or Al, 7% Si02. The target carrier forms a probe which can be positioned in the patient's mouth. X-rays are directed forwardly and laterally of the target to an X-ray film positioned externally. The probe is provided with a detachable sleeve having V-form arms of X-ray opaque material which serve to depress the tongue out of the radiation path and also shield the roof of the mouth and other regions of the head from the X-ray pattern. A cylindrical lead shield defines the X-ray beam angle. (author)

  18. Dental X-ray apparatus

    International Nuclear Information System (INIS)

    Intra-oral X-ray apparatus which reduces the number of exposures necessary to obtain panoramic dental radiographs is described in detail. It comprises an electron gun, a tubular target carrier projecting from the gun along the beam axis and carrying at its distal end a target surrounded by a shield of X-ray opaque material. This shield extends forward and laterally of the target and has surfaces which define a wedge or cone-shaped radiation pattern delimited vertically by the root tips of the patient's teeth. A film holder is located externally of the patient's mouth. A disposable member can fit on the target carrier to depress the patient's tongue out of the radiation pattern and to further shield the roof of the mouth. The electron beam can be magnetically deflected to change the X-ray beam direction. (author)

    There is a very complicated electrolytical environment in oral cavity with plenty of microorganisms existing there. Various forms of corrosion would develop when metallic prosthesis functions in mouth. One important corrosive form is microbial corrosion. The metabolic products, including organic acid and inorganic acid, will affect the pH of the surface or interface of metallic prosthesis and make a change in composition of the medium, thus influencing the electron-chemical reaction and promoting the development of corrosion. The problem of develpoment of microbial corrosion on dental alloy in the oral environment lies in the primary condition that the bacteria adhere to the surface of alloy and form a relatively independent environment that promotes corrosion.
