There are patients who complain bite discomfort without evident occiusal abnormalities, and this is one of the frustrating problems in dentistry. Among the various etiologies of this condition, "occiusal dysesthesia", the abnormalities of occiusal sense might be considered as one of the factors. Therefore, in this study, the thickness discrimination ability in healthy young dentate indivisuals, elderly dentate indivisuals, patients with complete dentures, and occiusal dysesthesia patients. was examined to get the basic information to investigate the feature of "occlusal dysesthesia".The interdental thickness discrimination test was performed at maxillary and mandibular central incisors, canines, premolars and molars with 2-, 5-, and 10-mm thickness standard blocks. The test block, whose thickness was different from the corresponding standard block, was applied after the application of the standard block, then subjects were asked to answer whether the test block was felt thicker or thin … More ner than the standard block. The number of wrong answers was submitted to the data analysis.With regard to theexperiment for twenty healthy dentate young adults, the reproducibility was confirmed. There were statistically significant differences in the number of wrong answers between 2-and 10-mm, and 5-and 10-mm thickness, respectively (P<0,05, ANOVA). Significantly more wrong answers were observed for the test blocks thicker than the standard block, than for those thinner than the standard block (P<0.05, ANOVA). Females reported significantly more wrong answers than males in thinner test blocks for 2-and 5-mm thickness (P<0.01, rigid analysis).More wrong answers were reported for the data obtained at premolar region than that at central incisor region. As forthe elderly participants and complete denture wearers, more wrong answers were reported than the young adults. Regarding occlusal dysesthesia patients, lastly, more wrong answers were reported than the young adults. However, there was not enough data to establish the threshold for discriminating occlusal dysesthesia patients from healthy subjects. Less

有些患者抱怨咬伤不适，但没有明显的枕骨异常，这是牙科中令人沮丧的问题之一。在各种病因中，“枕骨感觉障碍”，枕骨感觉异常可能被认为是其中一个因素。因此，在本研究中，健康青年牙齿个体视觉、老年牙齿个体视觉、全口义齿患者和尾觉障碍患者的厚度识别能力。为了解“咬合感觉不良”的特点，对其进行检查。采用2、5、10 mm厚度标准块分别对上颌中切牙、犬齿、前磨牙和磨牙进行牙间厚度判别试验。在使用标准块后，再使用与相应标准块厚度不同的测试块，然后要求受试者回答是否感觉测试块比标准块更厚或更薄。错误答案的数量被提交给数据分析。对20名健康有齿青年进行了实验，证实了实验的可重复性。2- 10-mm厚度、5- 10-mm厚度之间的错误回答数差异有统计学意义（P< 0.05，方差分析）。比标准块厚的测试块的错误答案明显多于比标准块薄的测试块（P<0.05， ANOVA）。在2 mm和5 mm厚度的较薄测试块中，女性报告的错误答案明显多于男性（P<0.01，刚性分析）。前磨牙区数据的错误答案多于中切牙区。至于老年参与者和全口义齿佩戴者，报告的错误答案比年轻人更多。最后，对于咬合感觉不良的患者，报告的错误答案多于年轻人。然而，没有足够的数据来建立区分咬合感觉障碍患者和健康受试者的阈值。少
