Relationship Between Drinking Water Fluoride LevelsDental Fluorosis Dental Caries and Associated Risk Factors in 9-12Years Old School Children of Nelakondapally Mandal of KhammamDistrict Andhra Pradesh India: A Cross-sectional Survey

摘要

>Background: The present study was conducted to assess the relationship between drinking water fluoride (F) levels, dental fluorosis and dental caries among 9-12 years old school children of Nelakondapally Mandal, Khammam district, Andhra Pradesh. >Materials and Methods: A cross-sectional analytical study was conducted on 1500 school children aged 9-12 years, selected by stratified random sampling from different areas with different levels of naturally occurring F in drinking water. The children were assessed for dental fluorosis according to WHO basic survey guidelines. The overall oral health status of the child was assessed by decayed missing filled teeth (DMFT)/dmft index. Statistical analysis was done using mean, standard deviation, standard error, Z-test, ANOVA test, and Chi-square test. >Results:The results of the present study revealed that the prevalence offluorosis was 74.9%. Number of children having dental fluorosis washighest in children who consume water from bore wells. Cariesprevalence in the study population was about 56.5%. Cariesprevalence and mean DMFT/dmft scores were least in children withoptimal F areas and highest in children with below optimal F areas.>Conclusion:There was moderate prevalence of fluorosis in Nelakondapally Mandalof Khammam district, and caries prevalence is high in areas belowoptimal F areas.>How to cite the article:Shanthi M, Reddy BV, Venkataramana V, Gowrisankar S, Reddy BV,Chennupati S.
