One of the critical steps in the process of identification is the sex determination of an unknown individual. Many studies have shown that sex can be determined using the human skeleton, especially by examining the pelvis and skull. Odontometric analysis of the human sexual variation has been less investigated, especially of primary dentition. Aim: To verify the presence of sexual dimorphism in primary teeth of local population of Faridabad, Haryana, India. Materials and Methods: The research was performed on dental casts of 500 children (250 boys and 250 girls, age range 3-5 years). Mesiodistal and buccolingual crown dimensions of maxillary and mandibular primary teeth were measured with a digital Vernier's caliper and were analysed for sexual dimorphism. Mann-Whitney-U test was used to check the statistical significance of difference in tooth dimensions among boys and girls. Results: Differences were found in the mean values of mesiodistal and buccolingual diameters of primary teeth, in which boys generally had larger crown diameters than girls. Conclusion: Primary teeth may be used as an additional tool for sex identification of juvenile skeletons where other dimorphic features are not much developed. © 2017, Journal of Clinical and Diagnostic Research.

Impacted teeth are those with a delayed eruption time or that are not expected to erupt completely based on clinical and radiographic assessment. The third molars can vary considerably in size; contour and relative position to the other teeth. Mandibular third molars were more often impacted as compared to the maxillary third molars. The mandibular third molars are the most frequently impacted teeth that can be found in humans. Data analysis shows that the prevalence of third molar impaction ranges from 16.7% to 68.6%. Impacted teeth are often associated with pericoronitis, periodontitis, cystic lesions, neoplasm, root resorption and can cause detrimental effects on adjacent tooth. © 2010 RJPBCS.

Age estimation is an important subspecialty of forensic medicine. Dental hard tissues are highly resistant to degradation and putrefaction. Enamel is translucent and varies in color from light yellow to grey white. The color of the teeth has been reported to be affected by chronological age. Enamel color may also depend on environmental factors viz. diet, occupational habits, vitamin deficiencies, fluoride level in drinking water etc., It has been found that color changes in dentin vary from white to yellow. Studies have been done to measure the dentin color for age estimation.To find a correlation between the enamel color and chronological age and secondly to estimate the age of an individual from enamel color.A total of 300 patients visiting the outpatient department of oral medicine and radiology were selected. Out of those, 150 were men and 150 women. The patients were divided into V groups based on the age. A thorough case history was taken for all the patients. Maxillary Central and Lateral incisor was used for the estimation of shade. The enamel color was evaluated using a VITA classical shade guide.Data were exported to an Excel spread sheet and statistical analysis was performed using the SPSS. Linear regression analysis was used to find correlations between age and enamel shade.In the group 1 and 2 i.e. from 15 to 36 years, the shades A 2 and B 2 (reddish hue) was found to be most common. While in the group 3 and 4, shades ranged from A 3 to B 3 (brownish to yellowish hue). In the patients above 59 years i.e. group 5 the enamel shade with greyish hue was found to be most common.Age determination using enamel color can be tried in forensic cases in the identification of individuals with no birth records.

Role of dentists in prevention and sustainable care of leprosy is known. Changing leprosy scenario has led to requirement of change in leprosy education. However, knowledge and attitude of dental students on leprosy remains unknown.Hence a study was conducted to assess knowledge and attitude of dental students about Leprosy.A questionnaire based, cross-sectional survey was conducted among 350 undergraduate and the postgraduate dental students of two dental colleges in Faridabad, India. The score for knowledge ranged from 0 to 16 and scores for attitude ranged from 0 to 26. These scores were further coded as poor, fair and good.Mean knowledge score for the sample was 7.643.23. A total of 32.29% participants were under poor knowledge category; 57.42% had fair knowledge about Leprosy while 10.29% had good knowledge. Mean attitude score was 15.5 5.98. A total of 30.57% had poor attitude scores, 42.57% had fair scores while 26.86% had good attitude scores. Univariate analysis showed year of training to be a significant predictor for knowledge level (t=7.12; p<0.001).The results indicate need for three important changes towards Leprosy in Dentistry. These changes are need for incorporation of leprosy education in Dentistry, need for incorporation of problem based as well as evidence based learning in Dentistry integrated with general health and need for reestablishing public health programs for Leprosy utilizing dental workforce.

In patients undergoing head and neck surgery for various pathologic conditions, implants are one of the best restorative options and are increasing widely used. Therefore, we evaluated the success of dental implants in the irradiated jaws of patients following treatment of oral cancer oral cancer treated patients.Data of oral cancer treated patients was collected retrospectively from 2002 to 2008. We took 46 oral cancer treated patients in which implants were placed in irradiated jaws for rehabilitation.It was found that out of 162 dental implants placed, 52 failed. Furthermore, there was no variation in the implant survival rate in between both the jaws. Radiation dose of <50 Gy units also showed significantly increased amount of implant survival rate.Implant survival is multifactorial and depends upon a number of factors like level of radiation exposure in that area, time gap between last radiation doses etc., Further research is required in this field to improve the esthetics and quality of life of cancer treated patients.

Oral submucous fibrosis (OSMF) is an insidious chronic disease that is associated with significant functional morbidity and an increased risk for malignancy. It initially affects the lamina propria of the oral mucosa, and, as the disease progresses, it involves the submucosa and deeper tissue, including muscles of the oral cavity, resulting in loss of fibroelasticity. OSMF is a pre-malignant condition mainly caused by areca nut chewing. The aim of this study was to find out the involvement of muscles of mastication and facial expression in patients with OSMF by assessing the cross-sectional thickness and activity of the masseter, anterior temporalis and orbicularis oris muscles by ultrasonography and electromyography and comparing with healthy controls and also to find out any correlation between the ultrasonographic cross-sectional thicknesses of the masseter, anterior temporalis and orbicularis oris muscles with electromyographic activity. Methods: 40 patients with OSMF were included in the study group, and the patients were divided into four groups on the basis of interincisal mouth opening, i.e. Group I (mouth opening >35 mm), Group II (mouth opening between 30 and 35 mm), Group III (mouth opening between 20 and 30 mm) and Group IV (mouth opening <20 mm). Ultrasonographic cross-sectional thickness and electromyographic activity (amplitude and duration) of the masseter, anterior temporalis and orbicualris oris muscles were recorded in patients with OSMF and 20 controls. Intergroup comparison of ultrasonographic cross-sectional thickness and activity (amplitude and duration) was done, and Pearson's correlation coefficient was applied to find out any relation between ultrasonographic and electromyographic findings. Results: Thickness and activity of the masseter muscle was significantly reduced in Group IV (mouth opening ,20 mm) when compared with the control group. The anterior temporalis and orbicularis oris muscles remained unaffected. A positive correlation was observed between the thicknesses of the masseter muscle and the amplitude in Groups I, II and III; the anterior temporalis muscle in Group II and the control group; and the orbicularis oris muscle in Groups II, III and IV. Conclusions: It was concluded that, among the muscles studied, there was an early involvement of the masseter muscle in patients with OSMF compared with that of other muscles. © 2014 The Authors.

Crouzons syndrome, also known as brachial arch syndrome, is an autosomal dominant disorder with complete penetrance and variable expressivity. Described by a French neurosurgeon in 1912, it is a rare genetic disorder. Crouzons syndrome is caused by mutation in the fibroblast growth factor receptor 2 (FGFR2) gene. Normally, the sutures in the human skull fuse after the complete growth of the brain, but if any of these sutures close early, then it may interfere with the growth of the brain. The disease is characterized by craniosynostosis, with associated dentofacial anomalies. This report describes the different clinical features in a 10-year-old male patient, with particular reference to characteristic findings of this syndrome.Kaushik A, Bhatia H, Sharma N. Crouzons Syndrome: A Rare Genetic Disorder. Int J Clin Pediatr Dent 2016;9(4):384-387.

Down syndrome is one of the most common congenital anomaly. It is most frequently caused by trisomy of chromosome 21. Other causes can be mosaicism and translocation. Such patients are commonly encountered in routine dental practice. This syndrome has wide range of medical and dental abnormalities. This paper presents a unique case of fusion and concrescence of retained primary teeth in a child with Down syndrome. The incidence of such anomalies is quite low in these cases. Thus, a better awareness of such conditions on part of a dental practitioner will aid in the provision of enhanced dental care to these patients.

Ameloblastic fibrodentinoma (AFD) is a debatable neoplasm with respect to its clinical, biological and histopathological diagnosis. The clinical and radiological presentation may mimic ameloblastic fibro odontoma, odontoma, ameloblastic fibroma and cemento-ossifying fibroma. We report an interesting case of AFD occurring in canine region of mandible in a one-year-old infant. From a review of English language literature, to the best of our knowledge this is the first case occurring in an infant. The purpose of this case report is to create awareness among the clinicians to make the best possible management of this controversial pathologic entity.
