II类错牙合畸形混合牙列期舌压与咀嚼功能之间的关系尚未明确。本研究的目的是确定混合牙列期 I 类和 II 类错牙合之间舌压相关因素的差异，包括颌面形态和咀嚼功能。本研究共纳入 56 名具有混合牙列的 I 类错牙合（12 名男孩，16 名女孩）或 II 类错牙合（16 名男孩，12 名女孩）的儿童。测量了所有参与者的身高、体重、握力、最大咬合力、最大舌头压力、咀嚼性能以及腐烂、缺失和补牙的数量。还评估了他们的头颅侧位片。比较 I 类和 II 类错牙合的所有测量值的平均值。皮尔逊相关系数用于确定每种类型的错牙合的最大舌头压力与其他变量之间的关联。 Ⅱ类错牙合组的最大舌压力、手握力和最大咬合力均显着低于Ⅰ类错牙合组（均p < 0.05）。 Ⅰ类组的最大舌压与握力、最大咬合力、咀嚼性能和SNB（蝶鞍、鼻根、B点）角度呈显着正相关（均p < 0.05），而Ⅱ类组则与身高、体重和中切牙唇倾角呈显着正相关（均p < 0.05）。混合牙列Ⅰ类和Ⅱ类错牙合病例中与舌压相关的颌面形态测量因素明显不同。在 I 类错牙合病例中，咀嚼能力和舌压呈显着正相关，但在 II 类错牙合病例中则不然。
The relationship between tongue pressure and masticatory performance during the mixed dentition period in cases of Class II malocclusion has not been clarified. The aim of this study was to determine differences in tongue pressure-related factors, including maxillofacial morphology and masticatory performance, between Class I and Class II malocclusions during the mixed dentition period. A total of 56 children with Class I malocclusion (12 boys, 16 girls) or Class II malocclusion (16 boys, 12 girls) with mixed dentition were included in the present study. Height, body weight, hand grip strength, maximum occlusal force, maximum tongue pressure, masticatory performance, and the number of decayed, missing, and filled teeth were measured in all participants. Their lateral cephalograms were also evaluated. The means of all measurements were compared between Class I and Class II malocclusions. Pearson’s correlation coefficients were used to determine associations between maximum tongue pressure and other variables for each type of malocclusion. The maximum tongue pressure, hand grip strength, and maximum occlusal force in the Class II malocclusion group were significantly lower than those in the Class I malocclusion group (all, p < 0.05). The maximum tongue pressure was significantly positively correlated with hand grip strength, maximum occlusal force, masticatory performance, and SNB (sella, nasion, B point) angle in the Class I group (all, p < 0.05), and with height, body weight, and labial inclination of the central incisors in the Class II group (all, p < 0.05). The maxillofacial morphometric factors associated with tongue pressure were clearly different between cases of Class I and Class II malocclusion with mixed dentition. Masticatory performance and tongue pressure were significantly positively correlated in cases of Class I malocclusion, but not in cases of Class II malocclusion.
