To investigate the relationship between movement of the tongue during swallowing and malocclusion, the relationship between the lingual-palatal contact duration associated with swallowing and maxillofacial morphology was examined by electropalatography, cephalometric radiography, and dental casts. Seventy-one subjects (35 men and 36 women, 18 to 38 years of age) with normal occlusion or various types of malocclusion were used. Simple correlation analysis showed correlations between the time required for swallowing and the angles-FH-U1, L6-MP, FH-MP and Go-measured by lateral cephalometric radiography. In multiple regression analysis, five angles-FH-U1, L6-MP, FH-Occ, FH-SGna and NF-MP-measured by lateral cephalometric radiography were chosen as the independent variables, and significant regression equations and multiple correlation coefficient were obtained. It was concluded that the lingual-palatal contact duration associated with swallowing observed by electropalatography differs among persons; this is closely related to the maxillofacial morphology and significantly correlated with the measurement items representing the rotation of the lower jaw and inclination of upper incisors.
为了研究吞咽过程中舌的运动与错牙合畸形之间的关系，通过电子腭图、头影测量X线摄影和牙模，研究了与吞咽相关的舌腭接触持续时间与颌面形态之间的关系。研究使用了71名年龄在18至38岁之间、具有正常咬合或各种类型错牙合畸形的受试者（35名男性和36名女性）。简单相关分析显示，吞咽所需时间与通过侧位头影测量X线摄影测量的角度——FH-U1、L6-MP、FH-MP和Go之间存在相关性。在多元回归分析中，选择通过侧位头影测量X线摄影测量的五个角度——FH-U1、L6-MP、FH-Occ、FH-SGna和NF-MP作为自变量，并获得了显著的回归方程和复相关系数。得出的结论是，通过电子腭图观察到的与吞咽相关的舌腭接触持续时间因人而异；这与颌面形态密切相关，并且与代表下颌旋转和上切牙倾斜的测量项目显著相关。
