The aim of this research project was to develop expert systems fot the differential diagnosis and etiological diagnosis in temporomandibular disorders (TMDs). In order to select the sufficient diagnostic factors for establishing the efficient diagnostic process and reliable criteria, the prevalence rates of clinical signs and symptoms, the coincidence rates and the strength of correlation among the signs and symptoms in TMD patients, were evaluated statistically. Furthermore, the bite force distribution on the dental arches in the normal subjects and TMD patients were analyzed by using pressure-sensitive foil "Dental Prescale".As the results, the characteristic patterns in occurrence of the clinical signs and symptoms were detected in TMD patients. It is suggested that these definite patterns peculiar to TMDs in clinical conditions could be utilised as the diagnostic criteria for differentiating TMD from others. The bite force distribution on the dental arches were symmetrical between the right and left arches in the normal subjects. On the other hand, those in the TMD patients were deviated from those in the normal subjects. According to this finding, the symmetry of bite force distribution would be the one of the contributions factors to the onset of TMD,and could be utilized as an indicator of occlusal factors in the etiological diagnosis.Based on these results, the project of developing the expert diagnostic systems for TMD are progressed at present.

本研究旨在开发颞下颌关节紊乱病（TMDs）鉴别诊断和病因诊断专家系统。为了选择足够的诊断因素来建立高效的诊断流程和可靠的标准，对TMD患者的临床体征和症状的患病率、体征和症状之间的符合率和相关性强度进行了统计评估。此外，还采用“Dental Prescale”压敏箔对正常人和TMD患者牙弓上的咬合力分布进行了分析，结果发现了TMD患者临床症状和体征的特征性模式。这些明确的临床表现可作为TMD与其他疾病的鉴别诊断标准。正常人左右牙弓咬合力分布对称。而TMD患者组则与正常人组存在差异。根据这一发现，咬合力分布的对称性可能是TMD发病的一个重要因素，并可作为诊断TMD病因的一个咬合因素指标。
