Context: The dental caries is a result of localized demineralization on tooth surface caused by metabolic events that occur in the dental plaque. Overall prevalence of early childhood caries (ECC) in general population ranges up to 70%. There are various studies conducted to find the association of ECC with various factors, yet very few studies have been conducted to predict and prevent the ECC before its occurrence. Aims: To perceive whether there is any correlation between blood group and ECC in children of Vadodara city. Settings and Design: The cross-sectional observational study was conducted among 120 selected children in a preschool. The students were segregated into two groups, 60 children with caries and 60 children without caries between chronological age of 2–6 years. Subjects and Methods: Blood group of the children was recorded from the blood group card of the patient, and dental caries status was recorded as decayed-extracted-filled teeth status with the help of autoclaved diagnostic instruments (mouth mirror and No. 23 explorer). Statistical Analysis Used: Kruskal–Wallis test, Mann–Whitney test, independent t-test, and Pearson Chi-square test were used for analysis. Results: From the total participants included in the study, blood group O+ showed maximum occurrence of ECC among all other blood groups. Conclusions: Children belonging to Vadodara city with blood group O+ are at high risk of getting ECC.
