Evaluation of adult dental patterns on orthopantomograms and its implication for personal identification: A retrospective observational study

BACKGROUND Establishing a persons identity is a very complex process and is one of the main objectives of the forensic science also. Dental radiographs are certainly one of the most desirable pieces of antemortem evidence because of their highly objective nature as compared with other records. The aim of the present study is to establish the utility of orthopantomography for human identification. MATERIALS AND METHODS A total of 300 digital orthomopantographs were randomly selected from those stored at Oral Medicine and Radiology Department of Dr. D.Y. Patil Dental College and Hospital, Pimpri, Pune. Dental patterns were classified into nine types which are commonly observed in dental radiography. The diversity of dental patterns was calculated for full dentition, maxilla and mandible respectively. RESULTS Diversity of dental patterns observed for full dentition, maxilla and mandible were found to be 99.9%, 98.2% and 98.4% respectively. CONCLUSION Findings suggests that orthopantomograms prove to be valuable aid in human identification.

Prevalence of dental caries, periodontitis, and oral hygiene status among 12-year-old schoolchildren having normal occlusion and malocclusion in Mathura city: a comparative epidemiological study.

OBJECTIVE The aim was to find the prevalence of dental caries, periodontitis, and oral hygiene index-simplified (OHI-S) among 12-year schoolchildren having normal occlusion and malocclusion in Mathura city. MATERIALS AND METHODS The present study was a cross-sectional study done among the 100 subjects who have been selected from 5 schools in four different geographical locations. The data regarding their socio-demographic characteristics, dental caries status, periodontitis status and oral hygiene status was collected using structured proforma. Means, standard deviations and test of significant were used as statistics to describe the data. RESULTS The results showed that there was no significant difference between dental caries status, periodontitis status among subjects having normal occlusion and malocclusion (P = 0.06, 0.093) but significant relationship was found OHI-S and children who were having malocclusion (and P = 0.022). Significant difference was also found between periodontitis and oral hygiene status (P = 0.00). CONCLUSION It was observed from the present study that normal occlusion and malocclusion had no or weak significant effect on overall caries and periodontitis prevalence whereas oral hygiene status had a strong effect on overall periodontitis prevalence but not in relation to prevalence of dental caries in 12-year-old school children in Mathura city.

Prevalence of Dental Caries and Oral Hygiene Status Among Blind School Children and Normal Children, Jodhpur City: A Comparative Study

of 704, 6-15 year school going children were selected out of them 354 children were blind and 350 children were normal. The data was recorded following the World Health Organization basic oral health survey 1997 criteria. The data was analyzed by using simple statistics including mean and percentages. Results: The study showed that the prevalence of dental caries was 60% and 31.5% in visually impaired and normal children respectively. The oral hygiene status showed that the mean value in good category was found to be 0.19 and 0.67, in fair category was 0.22 and 0.1 and in poor category was 0.40 and 0.23 in visually impaired children and normal children respectively. Conclusion: If dental health awareness can be instituted to the parents, including brushing techniques and diet counseling at a very early age, the incidence of dental caries can be kept to minimum, and can reduce the probability of complicated dental treatment needs. The oral hygiene habits of individuals with disabilities can be improved by close monitoring and periodic dental check-ups.

Portwine stain with nodular thickening and intraoral hemangioma

Vascular anomalies are a heterogeneous group of congenital blood vessel disorders more typically referred to as “birthmarks.” They are further categorized into vascular tumors and malformations, which are again subdivided into various types based on specific morphology, pathophysiology, clinical behavior and management of particular entity. Hemangiomas are the most common vascular tumors. Lymphatic, capillary, venous and arteriovenous malformations are the main subdivisions under the heading of vascular malformations. This paper discusses a case of co-occurrence of portwine stain with intraoral hemangioma.

Drug Induced Oral Mucosal Pigmentation- A Review

Medications may induce a variety of different forms of mucocutaneous pigmentation, including melanosis. This short review discusses about various drugs implicated in oral mucosal pigmentation and also pigmentation caused by heavy metal ingestion.

Bifid mandibular canal: Case report and review of literature

Bifid mandibular canals are often unrecognized. The detection of these anatomical variations is important because of its clinical implications. Special attention has to be paid in surgical procedures involving the lower jaw. Purpose of the present article is to provide an extensive review of literature of this anatomical variation and also we present one such case report.
