ABO blood group antigens, known to play roles beyond immunohematology, may contribute to craniofacial development and dental arch alignment. A cross-sectional research was conducted among 200 orthodontic patients aged 12-30 years. Blood group O showed a higher prevalence of Class I malocclusion (48.9%), while Class II was more common in group B (46.3%). Class III showed increased occurrence in group A (41.7%). A statistically significant association was found between ABO blood group and both malocclusion type (p=0.043) and severity (p=0.038). ABO blood group may be a predictive marker in malocclusion type and severity.
