A fundamental study on the diagnosis of occiusal dysesthesia

有患者抱怨咬合不适，但没有明显的咬合异常，这是牙科令人沮丧的问题之一。在此病的多种病因中，“枕性感觉障碍”可能是其原因之一。因此，在本研究中，厚度辨别能力在健康的年轻齿状个体、老年齿状个体、全口义齿患者和咬合感觉障碍患者中被检测。对上颌中切牙、尖牙、前磨牙和磨牙进行牙间厚度辨别试验，分别采用2 mm、5 mm和10 mm厚度标准块。厚度不同于相应标准块的测试块在施加标准块之后被施加，然后要求受试者回答测试块感觉更厚还是更薄…比标准积木更耐用。将错误答案的数量提交给数据分析。针对20名健康的齿状齿青年进行的实验，证实了该实验的重复性。厚度分别为2 mm和10 mm、5 mm和10 mm之间的错误答案数差异有统计学意义(P&lt；0.05，ANOVA)。对于比标准块厚的测试块，观察到的错误答案明显多于比标准块薄的测试块(P&lt；0.05，ANOVA)。在厚度为2 mm和5 mm的较薄试块中，女性报告的错误答案明显多于男性(P&lt；0.01，严格分析)。前磨牙区域的错误答案比中切牙区域的错误答案更多。对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，对于咬合感觉障碍患者，报告的错误答案比年轻人更多。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。较少

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
