Abstract
Objective: To assess the prevalence of dental caries and fluorosis among 7-12-year-old school children in Muradnagar, India. An additional objective was to determine the relationship between dental caries and fluorosis in the studied population. Material and Methods: A total of 1500 school children aged between 7 to 12 years, and both genders were randomly selected for the present study. The selected participants were divided into three groups based upon age, viz 7-8 year (group I), 9-10 year (group II) and 11-12 year (group III). Sterile mouth mirrors and explorers were used for the detection of caries. The water samples were collected to assess the fluoride concentration. The data collected were tabulated and statistically analysed using Chi-square, ANOVA, Spearman's correlation and t-test wherever applicable. Results: Out of 1500 participants, 54.1% were females and 45.9% were males. The prevalence of dental caries and fluorosis was 89.3% and 93.7%, respectively. The prevalence of caries increased with age (p<0.05) and females showed a higher prevalence in both the dentitions. Most dental fluorosis was 'very mild' (40.1%). Prevalence of dental fluorosis increased with age and males showed more fluorosis than females. A negative relationship was found between dental caries and fluorosis (p<0.05). Conclusion: Dental caries and fluorosis are the public health problems in Muradnagar; therefore, preventive programs should be organized to increase awareness among the general people.
