Prevalence of class I caries in the second mandibular primary molar in 3-6-year-old children.

Dental caries is the disease of the oral cavity with serious oral health concern. It affects 50% of the schoolchildren worldwide. The consequences affect quality of life and may lead to socioeconomic crisis. The study was undertaken with the aim to understand the prevalence of class I caries in the second mandibular primary molar in 3-6-year-old children. The data were collected from the institutional patient records between September 2020 and February 2021. Of 6828 children, 100 children with class I caries in the mandibular second molar were included in the study. Data analysis was performed to find the association. On analyzing the correlation between age and prevalence of class I caries, all the age groups (i.e., 3-6 years) have almost equal prevalence of class I caries in both left and right second mandibular primary molars. On analyzing the correlation between gender and prevalence of class I caries, male children constitute about 56% of overall prevalence. About 43% of female children constitute class I caries. From the present study, it shows that there is high prevalence of class I caries in the second mandibular primary molar in children of 3-6 years of age. Knowledge on caries pattern on individual teeth and risk factors will help control and reduce dental caries.
