Background and objective: The purpose of this study was to assess the prevalence of caries in children aged 8-13 years having dental fluorosis and to determine the correlation between the grades of dental fluorosis and caries.
Material and methods: 451 school children in the age group of 8-13 years were selected for the study and were divided into six age groups. The children were assessed for dental fluorosis according to Dean\'s criteria Index of fluorosis, and dental caries according to WHO basic survey guidelines. The overall oral health status of the child was assessed by DMFT index.
Results: The results of the present study revealed that the prevalence of grade 2 fluorosis was the highest and grade 5 fluorosis was the lowest in all the age groups. Number of children having dental fluorosis was highest in the age group between 12-13 years followed by the age group between 13-14 years. The overall DMFT increased as the age of the children increased in the different age groups. The DMFT increased as the severity of fluorosis increased upto grade 2 and then decreased from grade 3 to grade 5.
