Introduction: Telangana state in southern India has many areas which have high–low fluoride levels in drinking water, and Mahabubnagar district is one among them, where people are affected with dental and skeletal fluorosis, with the majority belonging to low socio-economic status. Aims: To assess the prevalence of dental fluorosis in school going children of Mahabubnagar district and also to assess fluoride levels in drinking water from different areas of Mahabubnagar district. Materials and Methods: A cross-sectional study was conducted on 2000 children in the age group 6–12 years in different areas of Mahabubnagar district. Dental fluorosis status was assessed by using Modified Dean’s Fluorosis Index. Alizarin visual method was used to estimate fluoride levels in water. The data collected were subjected to statistical analysis. Results: Dental fluorosis in primary and permanent dentition was 15 and 70.3%, respectively. In the northern part of Mahabubnagar district, primary dentition was more affected by fluorosis whereas in southern part, the permanent dentition was more affected. The prevalence of dental fluorosis in primary dentition was more in 6–7-year-old children (35.5%), and in permanent dentition, it was more in 9–10-year-old children (70%). The fluoride level in drinking water was more in Kosghi, Kalwakurthy (2.0 ppm). Conclusion: Dental fluorosis was more in 10-year-old and less in 6-year-old children. It was more in eastern and northern zones of Mahabubnagar district and less in local villages of Mahabubnagar.
