Data collected from standardized temporomandibular joint examination forms and treatment records of patients diagnosed as having Myofascial Pain Dysfunction Syndrome and treated using occlusal adjustment as the primary mode have been presented. A higher success rate was found in those patients: (1) with a chief complaint of pain confined to the area of one or both temporomandibular joints only, (2) whose answer to location of pain on initial examination was identified as confined solely to the region of one or both temporomandibular joints, (3) with muscle tenderness to palpation to one or both lateral pterygoid muscles with no other muscle involvement, (4) recorded as having a centric discrepancy in the absence of a balancing side prematurity, and (5) in the 31 to 40-year-old age group.

A large group of patients (236) was examined for myofascial pain dysfunction syndrome. The parameters used for diagnosis of the syndrome were pain and tenderness in the head and neck muscles and temporomandibular joint, joint sounds, and limited function. It was found that the demographic profile of our patient population did not vary greatly from those reported previously in other studies. However, we did examine more details of the patients' backgrounds than any other single study. The relationships of age, sex, occupation, marital status, emotional stress, and head trauma were discussed.

A large group of patients (236) was examined for Myofascial Pain Dysfunction Syndrome. The symptoms of the patients were recorded, using as a guide the classic parameters of pain and tenderness to the head and neck muscles and temporomandibular joint, joint sounds, and limited function. Our basic data were similar to those of other studies. The significant difference of this study is the detail with which the symptoms were studied. The relationships of suspected etiology and symptoms were compared and discussed. This paper is the second of a three part series. The first part dealt with the demographic profile of our patient population. The third part will present the data dealing with treatment modalities and relief.
