Temporomandibular disorder in adults: retrospective study

Abstract

BACKGROUND AND OBJECTIVES:The temporomandibular disorder (TMD) comprises clinical signs and symptoms involving masticatory muscles, the temporomandibular joint (TMJ) and associated structures, does not affect all people equally, and all individuals are not equally susceptible to it. The aim of this study was to investigate signs and symptoms present in individuals with TMD. METHODS: Cross-sectional study with 471 individuals with TMD, 394 women and 77 men, based on data from clinical records, diagnostic exams and treatment of patients seen at the Federal University of Pelotas, Brazil, from 2000 to 2017. RESULTS: Data showed that 84% of the individuals were women. The most prevalent age group was 20-39 years old (45%, p<0.01). The most reported main complaints were TMJ pain (29.9%, p<0.01) for both genders, and facial pain (18%, p<0.01). The most common signs and symptoms were muscle pain, TMJ pain, facial pain and clicks in women and parafunctional habits in men, followed by limited mouth opening and tension headache. Dentate patients were the majority in the study (58%, p<0.01), followed by partial edentates (30%, p<0.01). CONCLUSION: The data found showed a high prevalence of TMD and the importance of its prevention in order to improve the health and well-being of the population.

Influence of quality of total prostheses on the prevalence of temporomandibular disorder

“…It would be a confusing factor for our study if the female sex was a risk factor for TMD. However, although some authors 4,9,16 have found that the number of women seeking treatment for TMD is greater than the number of men, implying that females are more affected by the condition, this has been interpreted as a difference in attitude about oral health that reflects social, psychological, and behavioral discrepancies between the sexes.…”

“…The main signs and symptoms are pain in the muscles for mastication and/or TMA, sounds during condylar movement, and limitation or lack of coordinated jaw movement 3,4 . This pain triad appears together with mandibular disorder and articulatory sounds, as well as other clinical factors, including muscle and articulatory pain, palpation and during function, otalgia, tension headache, bruxism, trismus, limited mouth opening, pain in the cervical region, and static and dynamic abnormalities of the occlusal relationship 4,5 .…”
