Aim: The study aimed to assess early childhood caries and its correlation with risk variables among school children.
Materials And Methods: 242 children under the age of 5 years were clinically assessed and to ascertain early childhood caries, a validated structured questionnaire was utilized. Demographic data (four questions) and oral health-related activities questions (two questions) were included.
Introduction: Oral lichen planus (OLP) is a chronic inflammatory disease with cell-mediated immune dysregulation. The aetiology of OLP has been studied extensively for decades. Viruses like Hepatitis C Virus (HCV), human papillomavirus (HPV), herpes simplex virus (HSV), and stress have been hypothesized to play a role in the pathogenesis and malignant transformation of OLP.

- - The study compares the effectiveness of conventional film and photostimulable phosphor (PSP) imaging in detecting interproximal caries by using a stereomicroscope for direct measurement as a reference.
- - A sample of 200 proximal surfaces from 100 extracted teeth was analyzed, with three observers evaluating both imaging methods, and the study found good agreement among observers with kappa coefficients ranging from 0.8788 to 0.9583.
- - The results showed that while PSP had slightly better specificity (80%) compared to film (78.3%), there were no significant differences in diagnostic ability between the two methods, leading to the recommendation of PSP for detecting cavitated proximal caries, pending further research on
Lichen planus (LP) is a chronic inflammatory mucocutaneous disease. The disease has a cell-mediated immune reaction which is precipitated by a specific trigger which turns the self-peptides antigenic. The role of human papillomavirus (HPV) in the malignant transformation of oral LP (OLP) has always been debated.

Among the biomarkers of sub-chronic exposure to fluoride, hair, fingernails, and toenails have the advantage of being noninvasively collected, easily transported, and stored.
Objective: The objective of this study was to comparatively evaluate coronal hair, fingernails, and toenails as biomarkers of fluoride exposure from drinking water; the study was designed as a population-based observational cross-sectional study.
