Frequency of temporomandibular disorder diagnosis: a study on 102 patients undergoing dental treatment

Resumo

Epidemiological studies show that the prevalence of
temporomandibular disorders (TMD) is high, ranging from 9.8 to
74%, it is important that the diagnosis be made as early as possible
to avoid future clinical failure. Objective: To evaluate the prevalence
of TMD in patients attended at the School of Dentistry of Federal
University of Juiz de Fora (FO / UFJF), associated with age, gender
and clinical group. Material and methods: 102 patients of both
sexes were selected during treatment at FO / UFJF in Periodontics
I and II, Partial Denture (RPD), Total Denture (TD), Secondary Care
Clinic I and II disciplines, aged above 18 years-old. Patients were
submitted to axis I of the RDC / TMD. Results: Of the total sample,
53.9% had a diagnosis of TMD. Of these, 67.3% were female and
52.7% were between 41-60 years. The most prevalent diagnosis of
TMD was disc displacement with reduction corresponding to 18.6%
of the population. RPD and TD clinics were, in this order, those
who had more patients with diagnoses of TMD, respectively, 27.3%
and 25.5% of the sample with TMD. Conclusion: A considerable
proportion of patients had at least one sign or symptom of TMD.
The evaluated sample shows how relevant is the evaluation of
the masticatory apparatus as a whole, where teeth, muscles and
temporomandibular joints, are viewed with the same level functional
importance, regardless of which treatment the patient will receive.
