Is there a correlation between A, B, and O blood group system and dental anxiety in pediatric dental patients? An observational study

BACKGROUND: Anxiety and fear are significant challenges in pediatric dentistry, often leading to avoidance of dental treatment. Some studies suggest a potential link between the dopamine beta-hydroxylase gene and the ABO gene. As ABO blood group type is determined genetically, it could serve as a bioindicator for assessing the impact of genetics on personality traits. The association between blood types and personality characteristics has long been debated. METHODS: Eighty eligible children, meeting the inclusion criteria, were enrolled in the study. Blood group data were obtained from parents/guardians. Dental anxiety assessment was done using the RMS-Picture scale and pulse oximeter. RESULTS: The collected data were analyzed statistically. CONCLUSIONS: The study found no correlation between dental anxiety and ABO blood grouping.
