Association between Blood Groups and Body Mass Index on Dental Caries Experience among Individuals Aged 18–25 Years Old in Nellore City, Andhra Pradesh

Introduction: Dental caries is a prevalent public health issue that can be contributed by oral hygiene, diet, and dental plaque. While diet has a major impact on oral health, blood groups are significant hereditary factors. Research has looked into the connection between tooth decay and obesity, but there are not many studies on the relationship between blood groups and dental caries. Aim: This study aims to compare the effects of body mass index (BMI) and blood group on tooth decay in Nellore City aged 18–25 years. Methodology: To evaluate the relationship between blood groups and BMI on dental caries, a 4-month cross-sectional study involving individuals aged 18–25 was conducted. Anthropometric measurements were used to calculate BMI, and a legitimate certified pathologist and dentist noted blood groups. The decayed missed filled teeth (DMFT) index was used to assess dental caries. SPSS version 21 was used for data analysis. Results: Among study population, it was found that patients with low BMI and patients with AB Blood group are found to have more DMFT score. Conclusion: In patients aged 18–25, the study found no correlation between blood groups and BMI with dental caries.
