Accuracy of four dental age estimation methods in determining the legal age threshold of 18 years among South Indian adolescents and young.

The aim of this study was to compare the accuracy, specificity and sensitivity of four commonly used methods of dental age estimation in a sample of south Indian adolescents and young adults aged between 14 and 30 years, with an age threshold of 18 years, using receiver operating characteristic curves (ROC) and the area under the curve (AUC). A total of 1070 orthopantomograms (535 males and 535 females) of adolescents and young adults of south Indian origin were collected retrospectively and interpreted.

Legal age determined by a new threshold value of third molar maturity index in subjects with impacted mandibular third molars: An orthopantomographic study in south Indian adolescents.

Third molars are one of the few biological markers available for age estimation in juveniles, especially for the estimation of the 18-year-age threshold. Literature has indicated that impaction has an influence on the development of third molars, which could possibly result in age misclassifications. The present study is intended to identify an alternative cut-off value of the third molar maturity index (I3M) in impacted mandibular third molars and also to evaluate its applicability in estimating the major (≥ 18 years)/minor (< 18 years) status.

Materials And Methods: A cross-sectional study was conducted among the permanent residents of Nalgonda district of Telangana state, India.

Position Statement of IACDE for managing dental patients during COVID-19.

Coronavirus disease 2019 (COVID-19) has been a major health concern globally ever since it was declared as Pandemic by the World Health Organization in March 2020. Due to the evolving and contagious nature of coronavirus, it continues to remain a threat for dental health-care personnel. As the virus travels from person-to-person via direct contact through droplet inhalation, cough, and sneeze or through contact transmission, it remains infectious even through inanimate surfaces.

A Comparative Immunohistochemical Analysis of Langerhans Cells in Oral Mucosa, Oral Lichen Planus and Oral Squamous Cell Carcinoma.

Background: Langerhans cells (LCs) are immunocompetent cells resident within oral mucosa which, together with intraepithelial lymphocytes, play a role in mucosal defence. LCs play a role in the pathogenesis of Oral lichen planus (OLP), a chronic mucocutaneous disorder thought to result from cell-mediated immune damage. In oral squamous cell carcinoma (OSCC), LCs are thought to present tumour antigens to the lymphocytes.
