Abstract

We experience some cases that are difficult to diagnose as temporomandibular disorders (TMD) or not, even if it is well understood. In this study, we surveyed how medical and dental doctors grasp the concept of TMD, and what kinds of diseases they differentially diagnose. From 12, 518 patients who visited the Oral and Maxillofacial Surgery Department of Saitama Medical University for five years from 2000 to 2004, and 4, 964 patients who visited the Oral and Maxillofacial Surgery Department of Tokyo Medical and Dental University for one year in 2004, which totaled 17, 482 patients, patients who had a letter of introduction regarding TMD were extracted and evaluated as to whether our diagnosis was the same or not, and if it was not the same, what the diagnosis was. The subjects were 359 patients in total, 225 patients in Saitama Medical University and 134 patients in Tokyo Medical and Dental University. In these cases, 39 patients were not diagnosed as TMD: 8 cases were diagnosed such as traumatic arthritis and dislocation of temporomandibular joint (TMJ) classified into diseases of TMJ without TMD and 31 cases such as teeth, periodontitis, psychological disease and somatoform disorder classified into diseases without TMJ diseases.
