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.
