Acquaintance with the behavior of children in dental office setting is highly important in treatment success. People with different blood groups often have different behaviors. Thus, the blood group may aid in prediction of behavior of pediatric dental patients. This study is aimed at assessing the relationship of the blood group with level of cooperation of pediatric dental patients. This cross-sectional study was conducted on 130 children between 4 and 6 years of age. The blood group of children was recorded according to their identification card or by collecting an intraoral blood sample during pulpotomy and using the respective kit. To assess the level of cooperation of children, their behavior was videotaped during the procedure, and the videos were assessed by two pedodontists. The behavior of children was scored according to the Venham scale. Data were analyzed by SPSS 26 and Chi-square, Fisher's exact test, and Mann-Whitney test. The blood group was A in 35.7%, B in 5.8%, AB in 3.2%, and O in 53.5%. Children with blood group O had maximum cooperation (52.6) while those with blood group B had minimum cooperation. Pairwise comparisons of the groups regarding the Venham scale revealed significant differences between blood groups A and B ( = 0.0001) and also B and O ( = 0.005). Pairwise comparisons of the groups regarding the level of cooperation also revealed significant differences between blood groups A and B ( = 0.0001) and B and O ( = 0.019). Blood group B may be correlated with certain behavioral traits such as dental fear and anxiety and the resultant poor cooperation.
了解儿童在牙科诊室中的行为对于治疗成功至关重要。不同血型的人通常具有不同的行为。因此，血型可能有助于预测儿科牙科患者的行为。本研究旨在评估血型与儿科牙科患者合作水平的关系。这是一项横断面研究，共纳入 130 名 4 至 6 岁的儿童。根据儿童的身份证记录其血型，或在牙髓切断术中采集口腔内血样并用相应试剂盒采集。为了评估儿童的合作水平，在手术过程中对其行为进行录像，然后由两位儿童牙科学者对录像进行评估。根据 Venham 量表评估儿童的行为。使用 SPSS 26 进行数据分析，并进行卡方检验、Fisher 确切检验和 Mann-Whitney U 检验。血型为 A 的占 35.7%，B 型占 5.8%，AB 型占 3.2%，O 型占 53.5%。O 型血的儿童合作度最高（52.6%），而 B 型血的儿童合作度最低。根据 Venham 量表对各组进行两两比较，发现 A 型和 B 型（ = 0.0001）以及 B 型和 O 型（ = 0.005）之间存在显著差异。根据合作水平对各组进行两两比较，也发现 A 型和 B 型（ = 0.0001）以及 B 型和 O 型（ = 0.019）之间存在显著差异。B 型血可能与某些行为特征相关，如牙科恐惧和焦虑，从而导致合作不佳。
