It is recommended that forensic odontologists discontinue the use of hand tracing overlays in bite mark comparison cases as there is lot of scope for manipulation and observer bias.

Aim: To determine the preponderance of oral mucosal lesions and conditions in patients receiving highly active antiretroviral therapy (HAART) for Human Immunodeficiency virus (HIV). Material and Methods: Patient tested Seropositive for HIV and on HAART therapy were clinically examined to evaluate prevalence of oral lesions. Results: In the pool of 152 HIV positive patients in the study, age ranged from 7 to 71 years, 67 were males and 85 females. The duration of the HAART medication was 43 months. Oral lesion was present in 51.32% of patients related to infection. Oral lesions seen in descending order of frequency were periodontitis, mucosal hyperpigmentation, acute gingivitis, oral candidiasis, linear gingival erythema, stomatitis, and nonspecific ulcers. Totally, 48.68% of patients had no oral lesions. Conclusion: Majority of the HIV patients on HAART exhibited periodontitis (30.77%), mucosal hyperpigmentation (17.44%), gingivitis (10.77%), anemic stomatitis (11.28%), and other oral lesions accounted to 29.74% which may be attributed to Anti Retro Viral Therapy.

Abstract:The position of mental foramen varies in different ethnic groups. Precise identification of the mental foramen is important in diagnostic and clinical procedures to prevent repeated local anesthesia failures and damage to neurovascular bundles passing through it. The aim of the study was to evaluate the most common radiographic position and symmetry of the mental foramen on panoramic radiographs in relation to the adjacent teeth. Four hundred and eighty panoramic radiographs of dentate Indian patients were interpreted. Radiographically in 48.96% of cases, the mental foramen was located in line with the second premolar and was common in age group of 25-35 years and in 40.83% was in between the first and second premolars. The position of mental foramen was symmetrical in 74.6% of cases and asymmetrical in 25.4% of the radiographs analyzed. In the present study, the most frequent position of the mental foramen was in line with the second premolars and was symmetrically placed. Knowledge of the most common location of the mental foramen among Indian population may enable effective regional anesthesia during dental procedures.

Abstract:Odontogenic fibroma is a rare tumour of odontogenic mesenchymal origin, which accounts for only 0.1% of all odontogenic tumours and can be seen either in maxilla or mandible. Though it is seen in second and third decade of life, cases have been reported in the age range of 5-80 years. Trismus is a rare clinical presentation of this tumour. As there is seldom any malignant change or recurrence, the treatment of choice is surgical enucleation. Here, we present a case of odontogenic fibroma in a 6-year old child, who presented with trismus as a chief complaint.
