DEVELOPMENT OF OBJECTIVE METHODS FOR DIAGNOSING OCCLUSAL DYSESTHESIA

有些患者抱怨咬合不适，但没有明显的咬合异常，这是牙科中令人沮丧的问题之一。在引起这种“牙合感觉障碍”的众多病因中，牙合感觉异常可能是其中一个因素。因此，本研究采用2 mm、5 mm和10 mm厚的标准试块，对正常人和牙合感觉障碍患者的牙间厚度辨别能力和心理状态进行了测试，以建立诊断牙合感觉障碍的客观方法。在应用标准块后，应用厚度与相应标准块不同（每隔0.25 mm，最大±1.5 mm）的试验块。然后，要求受试者回答测试块是否比标准块更厚或更薄。错误答案的数量W ...更多信息 提交给数据分析。至于健康的成年人的实验，有统计学上的显着差异，错误的答案之间的数量2-和10-mm，5-和10-mm的厚度，分别。厚于标准试块的错误率显著高于薄于标准试块的错误率，而对于感觉迟钝患者，厚于标准试块的错误率显著高于薄于标准试块的错误率。而正常人与感觉迟钝患者的错误回答数差异无统计学意义。总的来说，咬合感觉障碍患者的牙间厚度辨别能力与健康人没有显著差异。在心理测试方面，几乎所有的咬合感觉迟钝患者都至少有一个与心理方面有关的问题。因此，咬合感觉障碍与心理异常状况有关。少

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
