Key Points

A significant negative correlation exists between dental fluorosis and dental caries prevalence.
Lower levels of dental fluorosis were associated with higher occurrences of dental caries among the children.
The study analyzed data from 1800 children aged 6–12 using various statistical methods.
Effective fluoride monitoring and oral health education in schools are crucial for managing these dental issues.

Abstract

Introduction: This study examines the correlation between dental caries and fluorosis among schoolchildren in fluoride-endemic regions of Odisha. Materials and Methods: An epidemiological study was conducted among 1800 schoolchildren (6–12 years) from three districts with varying fluoride exposure. Fluoride levels in drinking water were measured using the ion-selective electrode method. Data were analyzed using SPSS 17.0 (IBM, Chicago, United States of America) with statistical tests, including the Mann–Whitney U -test, Chi-square test, and Spearman’s correlation. Result: A significant negative correlation (−0.237, P = 0.001) was found between fluorosis and dental caries, indicating that lower fluorosis levels corresponded to higher caries prevalence. Conclusion: Fluoride reduces caries but increases fluorosis, requiring effective monitoring and school-based oral health education.
