目的：本研究旨在通过比较全口义齿患者的局部电流感知阈值（CPTs）和疼痛阈值（PTs）来研究下颌骨是否比上颌骨更容易接受外部刺激。由一名术者测量切牙孔和腭大孔区左侧的上颌骨以及颏孔区左侧的下颌骨，使用NeurometerCPT/C装置，分析20名佩戴全口义齿的无牙颌个体的口腔粘膜的CPT和PT值。参与者的特征，如粘膜厚度，咬合力，年龄和性别。由同一操作者使用Krupp SDM和咬合力计GM 10 s装置测量目标区域上的粘膜厚度和咬合力。CPT和PT之间的三个测量区域的差异进行了测试，协方差分析，事后t检验与Bonferroni correction.Results：有没有显着差异之间的颏孔，切牙乳头，和大腭区CPT值。在所有电流频率（2000 Hz、250 Hz和5 Hz）下获得的PT在颏孔区最低，在大腭区最高。协变量，包括性别，粘膜厚度，咬合力没有显着影响CPT或PT值在所有frequency.Conclusions：下颌骨表现出更高的接受外部疼痛刺激比上颌骨。(C)2019日本口腔修复学会。由爱思唯尔有限公司出版。保留所有权利。
Purpose: This study aimed to investigate whether the mandible is more receptive to external stimuli than the maxilla in patients with complete dentures by comparing regional current perception thresholds (CPTs) and pain threshold (PTs).Methods: A single operator obtained measurements from maxillae at the incisor foramen and the left side of the greater palatine foramen region and the mandible at the left side of the mental foramen region, using the Neurometer CPT/C device, CPT and PT values from the oral mucosa of 20 edentulous individuals wearing complete dentures were analyzed. Participant characteristics such as mucosal thickness, occlusal force, age, and sex. Mucosal thickness over target regions and occlusal force were measured by the same operator using Krupp SDM and Occlusal Force-Meter GM10s devices. Differences in CPT and PT among the three measurement regions were tested with an analysis of covariance, and post hoc t-tests with the Bonferroni correction.Results: There were no significant differences between the mental foramen, incisor papilla, and greater palatine regions CPT values. PTs obtained at all current frequencies (2000 Hz, 250 Hz, and 5 Hz) were lowest in the mental foramen region and highest in the greater palatine region. Covariates including sex, mucosal thickness, and occlusal force had no significant influence on CPT or PT values at all frequencies.Conclusions: The mandible exhibits higher receptivity to external pain stimuli than the maxilla.
