项目摘要

There are patients who complain bite discomfort without evident occlusal abnormalities, and this is one of the frustrating problems in dentistry. Among the various etiologies of this condition, "occlusal dysesthesia", the abnormalities of occlusal sense might be considered as one of the factors. Therefore, in this study, the thickness discrimination ability and psychological aspects in healthy individuals and occlusal dysesthesia patients was examined to develop objective methods for diagnosing "occlusal dysesthesia".The interdental thickness discrimination test was performed at maxillary and mandibular central incisors with 2-, 5-, and 10-mm thickness standard blocks. The test blocks of which thickness were different (every 0.25 mm, ±1.5 mm maximum) from the corresponding standard block were applied after the application of the standard block. Then, subjects were asked to answer whether the test blocks were felt thicker or thinner than the standard block. The number of wrong answers w … More as submitted to the data analysis. With regard to the experiment for healthy dentate adults, there were statistically significant differences in the number of wrong answers between 2-and 10-mm, and 5-and 10-mm thickness, respectively. Significantly more wrong answers were observed for the test blocks thicker than the standard block, than for those thinner than the standard block.Regarding occlusal dysesthesia patients, the difference between thicker test blocks and thinner ones was more marked than that of healthy adults. However there were no statistically significant difference between the number of wrong answers of healthy individuals and that of occlusal dysesthesia patients. In conclusion, occlusal dysesthesia patients, in total, have no significant difference from healthy dentate individuals as for interdental thickness discrimination ability. With respect to the psychological tests, almost all occlusal dysesthesia patients had at least one problem related to psychological aspects. Hence, it was suggested that occlusal dysesthesia has correlation with psychologically abnormal conditions. Less

有患者抱怨咬合不适而没有明显的咬合异常，这是牙科中令人沮丧的问题之一。在咬合感觉障碍的多种病因中，咬合感觉的异常可能是其原因之一。因此，本研究通过对健康人和咬合感觉障碍患者的厚度辨别能力和心理方面的研究，建立了诊断“咬合感觉障碍”的客观方法。采用2 mm、5 mm和10 mm厚度标准块对上颌中切牙和下颌中切牙进行牙间厚度辨别试验。在施加标准块后，施加厚度与相应标准块不同的测试块(每0.25 mm，最大±1.5 mm)。然后，受试者被要求回答测试积木感觉比标准积木厚还是薄。…中错误答案的数量提交给数据分析的更多。对于健康齿状成年人的实验，2 mm和10 mm厚度的错误答案数量以及5 mm和10 mm厚度的错误答案数量分别在统计学上有显著差异。对于咬合感觉障碍患者，厚于标准块的测试块与薄于标准块的测试块之间的差异显著高于健康成人。然而，健康人和咬合感觉障碍患者的错误答案数量之间没有统计学意义的差异。总体而言，咬合感觉障碍患者在牙间厚度辨别能力方面与健康的齿状齿患者没有显著差异。在心理测试方面，几乎所有的咬合感觉障碍患者都至少有一个与心理方面有关的问题。提示咬合感觉障碍与心理异常有关。较少
