Purpose: Gingival growths are one of the most frequently encountered lesions in the oral cavity. Most of these lesions are innocuous, but some do have malignant potential. Different lesions with similar clinical presentations make it difficult to arrive at a correct diagnosis. One of the infrequently occurring gingival lesions is peripheral ossifying fibroma (POF). Lesions with histological features similar to POF have been given various names, adding to the confusion. We report the varied clinicopathological features of 3 cases of POF, discuss the contentious nomenclature and investigate the possible etiopathogenesis of this disease.Case description: Three cases of gingival growths (POF) are reported. Two of the lesions occurred in the maxillary anterior region, while the third occurred in the mandibular posterior region. Two of the cases showed radiographic evidence of bone loss. An excision biopsy was performed in all three cases.Conclusion: Because the rate of recurrence for peripheral ossifying fibroma is 8% to 20%, close postoperative monitoring is required. It is also necessary to use consistent and specific nomenclature in the literature to avoid confusion and the loss of important data.Key words: Fibroma; gingival overgrowth; peripheral ossifying fibroma ResumoObjetivo: Crescimentos gengivais são uma das doenças mais frequentemente encontradas na cavidade oral. A maioria dessas lesões são inócuas, mas alguns têm potencial maligno. Lesões diferentes com apresentações clínicas semelhantes tornam difícil um diagnóstico correto. Uma das lesões gengivais que ocorre raramente é o fibroma ossificante periférico (FOP). Lesões com características histológicas semelhantes ao FOP têm nomenclatura diferente, aumentando a confusão. Este artigo relata as características clinico-patológicos de 3 casos de fibroma ossificante periférico.Descrição do caso: Três casos de FOP são relatados. Duas das lesões ocorreram na região anterior da maxila, enquanto a terceira localizava-se na região posterior da mandíbula. Dois dos casos apresentaram evidências radiográficas de perda óssea. Biópsia excisional foi realizada em todos os três casos.Conclusão: Como a taxa de recorrência para FOP é de 8% a 20%, o monitoramento pós-operatório é necessário. Deve-se utilizar nomenclatura consistente e específica na literatura para evitar confusão e perda de dados importantes.
Objective: Though the soft palate presents with varied morphology, very few studies have described its diversity. The aim of our study was to investigate various shapes of soft palate in normal individuals. Methods: The study comprised of 80 individuals requiring orthodontic treatment but without any speech abnormality, whose age ranged from 9 to 31 years. Velar shape was examined on digital lateral cephalograms and was allocated to one of the six patterns as described by You M et al. The difference in proportion of each type and also difference between genders were studied. Results: The normal soft palate can be classified into six types based on its shape. Type 2-rat-tail shape is most common in both the genders. There is no significant difference in proportion of various shapes of soft palate between genders. Conclusion: Soft palate may have variable morphology. Knowledge of varied spectrum of velar morphology may help in successful functional and structural repair in cleft palate cases, and shed some light towards the causes of obstructive sleep apnea and related disorders.
Background & Objectives: Hepatitis B is the most important infectious occupational disease for the health care workers. Dental surgeons are frequently in contact with blood and saliva and hence are at high risk for Hepatitis B Virus (HBV) exposure. HBV infection is a major public health problem in India, as there are 45 million estimated carriers. Immunization against HBV reduces the risk of transmission of HBV to dental personnel and from dental personnel to patients. The present study was aimed to evaluate the serum levels of anti-HBs in vaccinated dental health care workers. Methods: In this study, estimation of serum levels of Anti- HBs in 40 dental students vaccinated against HBV was done. Data was obtained regarding vaccination data, age, sex, weight, height and smoking history. Anti-HBs level was evaluated two years after the 1st dose of vaccination. Low responders were given booster vaccination and post booster anti HBs assay was done. Results: The study included 110 hepatitis B vaccinated dental students. Out of 110 students only 40 students had documented history of complete vaccination and volunteered to be a part of the study. Among these 40 students, three students (7.5%) had less than 100 IU/L anti–HBs level and 37 students (92.5%) had more than 100 IU/L anti–HBs level. Anti- HBS level above 100 IU/L is identified to be protective. Following booster vaccination, low responders showed anti -HBs titre more than 100 IU/L. Conclusion: In this study majority dental students had desirable immune response to the HBV vaccine. Male gender and positive smoking history could have attributed to low anti-HBs titre in subjects who had inadequate levels in our study. Hence, all Health Care Workers, in particular dental surgeons with contributory factors like smoking habit, male gender should undergo periodic assessment of anti-HBs titre.
Objecitves: Radiomorphometric indices on dental radiographs can be used for screening of osteoporosis. However population-specific normative data is sparse. Aim was to establish radiomorphometric indices in Indian population and to determine role of age, gender and dentition on these indices. Materials and Methods: Cross sectional study was undertaken from January 2010 to December 2010. OPGs of 80 samples were divided into four age groups. Mental index, panoramic mandibular index, mandibular cortical index, antegonial index were measured. Relationships with age and dentition were analysed using Statistical Package for the Social Sciences SPSS12.0. Student t-test, one way analysis of variance, Chi square test was used to find the statistical significance. P value < 0.05 was considered to be significant. Results:In most of the study population endosteal margins of the mandibular cortex were even and sharp on both sides i.e.C1 appearance except in 60-69 years females who showed increased tendency of lacunar cortical defects i.e. C2 appearance. No correlation between dentition and mandibular cortical index (MCI), mental index (MI), panoramic mandibular index (PMI) & Antegonial index (AI) (p value 0.583, 0.059, 0.491 respectively). Population's mean of AI, MI, and PMI among males were 3.33, 3.97, 0.33 respectively and among females were 3.06, 3.64, and 0.32 respectively. (p value for AI, MI, PMI were 0.048, 0.028,0.037 respectively). Conclusions: All indices negatively correlated with age. There was a general downward trend with age until sixth decade, when values declined sharply. No statistical significance was found between AI, MI, and PMI and dentition.
Aim: Easy availability, overuse, and lack of reinforcement of the radiation hazards facts have unknowingly resulted in overlooking of as low as reasonably achievable (ALARA) among many dentists. The current survey was designed to assess the awareness, concern, and practice of radiation protection in general dental practice. Materials and Methods:The survey involved 156 dentists in West Bengal, India. A cross-sectional self-administered questionnaire consisting of a total of 28 items was employed. The obtained data were compiled systemically and significance of difference was calculated by Chi-squared test using Statistical Package for Social Sciences 17. Results: Bisecting angle technique and use of E-speed films with manual processing were the most common. The majority of the participants had no idea about the type of cone used (37.2%), tube current (37.8%), kVp 56.4% (88). Exposure time was equally variable with maximum variability in the case of digital radiographs. Use of lead barriers and aprons were poor. Conclusion:The knowledge and practice of radiation protection are not satisfactory. Repeated reinforcement and training and the most importantly change in attitude to follow ALARA is required.
