Epidemiological studies on odontogenic tumours conducted in different parts of the world emphasised variation in incidence and distributional pattern. Such epidemiological studies are obscured in Southern state of Andhra Pradesh in India. Present study was conducted at an institutional setup in South Indian population to assess the demographic data of odontogenic tumours. The retrospective study, which included all the odontogenic tumours from the archives of department of oral pathology, Dental teaching and Research Institution in southern part of India. Cases were selected based on the classification of WHO 2005 histopathological typing for odontogenic tumours and the assessment year considered was from 2002 to 2014. Demographic data was analysed for these tumours. Results were analysed using Chi-Square Test. Incidence of the odontogenic tumours was found to be 2.17%. Peak age incidence was recorded highest in third and fourth decade of life. Males were commonly involved [59%] with the male to female ratio of 1.43:1. Posterior mandible [53.4%] was the chief anatomical location involved with the tumours. Considering the individual lesions, Ameloblastoma [49%] was found to be more frequent, followed by Keratinizing cystic odontogenic tumour [32%], Odontome [6.2%], Adenomatoid odontogenic tumour [5.5%], Odontogenic myxoma [2.4%], Ameloblastic fibroma [0.6%], Calcifying epithelial odontogenic tumour [1.8%] and Squamous odontogenic tumour [1.2%]. The total frequency of odontogenic tumours was 2.17%. Ameloblastoma and Keratinizing cystic odontogenic tumours were the predominant tumours, demonstrating significant regional and geographic variation.

BACKGROUND: The progress in the usage of technology in hardware, software, and cost-effective Internet connectivity enable the availability of science-related information and its usage in all the developing countries. Hence, in this practical world, there should be a need to implement effective and affordable dental education strategies to attain oral health for all in the coming years. OBJECTIVE: The aim of this study is to reduce the need to teach theory-based, on-site classes, e-learning came into existence. E-learning for dental education may alleviate the burden of severe health worker shortages and deliver affordable access to high-quality dental education. METHODOLOGY: Evaluation and assessment methods were done to know the effectiveness of e-learning in dental education by conducting continuing dental education on newer materials and methods, assignments/formative assessments and by open discussions of case descriptions and their treatment modalities through Edmodo app in our dental institute. Effect on knowledge, skills, attitudes, and satisfaction levels of dental students compared to other traditional methods. RESULTS: Dental e-learning has the capacity to develop into a leading-edge to strengthen clinical training skills among dental students by conducting continuing dental education, assignments, formative assessments, case descriptions, and their treatment modalities through e-learning are the best ways to improve quantity and quality in dental education. CONCLUSION: The probable prospective of e-learning could be innovative or revolutionary because this helps in both theoretical-related and clinical-related advancements, and it is possible only with e-learning in developing countries to meet the quality in education.

Background: This study is aimed to evaluate the use of epithelial cells adhering the acrylic removable partial denture in establishing the sex of the individual using sex-determining region of the Y chromosome (SRY) gene. With a hypothesis that prosthetic appliance can also be used as a source of DNA in forensics for sex determination. A sample of 30 partial dentures from different denture wearers was selected for this study. Informed consent was taken from the subjects and institutional ethical clearance was obtained for this study. Samples were then washed in saline and scrapings from 0.5 × 0.5 cm 2 of the tissue contacting surface were taken using a blade of fixed thickness. DNA extraction was done from these isolated epithelial cells using Real Genomics YGB 100 (Real Biotech Corporation, Taiwan). Quantification and purity assessment of the extracted DNA was done using a Nanodrop ND-1000 spectrophotometer and clean DNA was subjected to real-time PCR amplification using SRY sex-typing marker for the detection of the presence of the SRY gene. Results: Isolation of epithelial cells and extraction of DNA from all 30 acrylic removable partial dentures were possible. Average DNA yield quantified from all samples was 32.37 ng/μl with a minimum yield of 2.17 ng/μl and a maximum yield of 117.57 ng/μl. On amplification of the target sequence, sex determination was possible from all samples with 100% accuracy. Conclusion: Acrylic removable partial denture can also be used as a source of DNA in forensics for sex identification.

Aim:To investigate and record the palatal changes in individuals habituated to reverse chutta smoking in rural coastal Andhra population.Materials and Methods:Sixty individuals out of whom 47 females and 13 males habituated to reverse smoking with no other tobacco and alcohol habits and no other systemic disturbances were selected. The palatal changes were recorded by six examiners. Database were searched for the following terms “reverse smokers,” “nicotina palatini” and “palatal lesions.”Results:The mean and percentage prevalence of the each lesion recorded and agreed by six examiners among 60 subjects showed presence of 87.77% hyperpigmented areas, 64.44% depigmented areas, 51.66% excrescences, 32.22% potentially malignant lesions and 9.72% frank ulcerations.Conclusion:Reverse smoking is an endemic tobacco habit still practiced in the coastal rural Andhra Pradesh. It is a well-established and socially acceptable habit among adult females. The changes recorded clinically shows characteristic features that are unique among this population group.
