A preliminary protocol for multi-professional centers for the determination of signs and symptoms of temporomandibular disorders.
The objective of the present study was to test a protocol for the quantification of the frequency and severity of signs and symptoms of temporomandibular disorders (TMD) according to patient perception during two phases of investigation. The protocol was developed based on the signs and symptoms most frequently reported in the literature and on the circumstances in which they produce discomfort. Eighty-four patients diagnosed with TMD by functional examination of the masticatory system responded to the protocol questions and indicated the severity of signs and symptoms using an eleven point numerical scale (Phase 1). Forty-two patients were fitted with an occlusal splint (treated group) and the remaining participants did not use a splint (control group). The protocol questions were asked after 50 days of treatment (Phase 2). Based on the results of nonparametric statistical analysis, the incidence of signs and symptoms was high in Phase 1 and significant, with no difference between the groups, whereas the treated and control groups differed in Phase 2. A comparison between Phases 1 and 2 showed that only the treated group presented a reduction in the severity of signs and symptoms. The study showed that using this protocol, it is possible to define the frequency and severity of symptoms as well as the effect of the treatment. The advantage of this protocol is that it would complement the data obtained using clinical examination with information provided by the patient in a measurable manner.
