BHARDWAJAbstract The aim of this study was to investigate the oral health status and fluorosis prevalence among the students of Ropana village of Mu ka tsa r district of Punjab, India. The epidemiological survey was conducted on rural school children studying Government Primary and Senior Secondary School's. A total of 512 subjects (244 boys and 268 girls ) aged 5-16 years were examined for dental fluorosis using Deans Index. Clinical examination were made during class hours.The maximum degree of dental fluorosis varied 10% to 80%. Maximum degree of dental fluorosis was 82.5% among the students in the age group of 12-16 years. 10% had questionable degree of fluorosis, 21.8% had very mild, 19.9% had mild and 13.6% had moderate type of fluorosis while 14.4% had severe degree of fluorosis. The prevalence of dental fluorosis was significantly higher in children who had consumed high fluoride water throughout their lives (5.0 mg/ L).Apart from fluoride in drinking water, other source of fluoride such as use of fluoridated dentrifices and dietary habits may partly explain the high prevalence and severity of dental fluorosis in school children.
