Prevalence of Temporomandibular Disorders in an Adult Brazilian Community Population Using the Research Diagnostic Criteria (Axes I and II) for Temporomandibular Disorders (The Maringá Study)

Abstract

The primary objective of this study was to assess the prevalence of temporomandibular disorders (TMDs) and comorbid factors (sleep bruxism and headaches). This study was a cross-sectional population survey in the city of Maringá, state of Paraná, Brazil. Materials and Methods: Axes I and II of the Research Diagnostic Criteria for TMD (RDC/TMD) were used for assessment of TMD signs and symptoms. The population was users of the Brazilian public health system (SUS), of both sexes, between the ages of 20 and 65 years, and not seeking treatment for TMD. Results: The selected population (N = 1,643) was composed mostly of (a) women (65.9%), (b) married or single individuals (90.6%), (c) Caucasians (70.1%), (d) individuals aged 32.7 ± 10.3 years, (e) individuals earning a medium income (75.1%), and (f) those who had completed a high school education or higher (79.9%). According to the chronic pain grade classification (CPG) in the RDC/TMD Axis II, 36.2% of the population had some degree of TMD pain (CPG I to IV); however, only 5.1% had severe limitation due to pain (CPG III or IV). In the RDC/TMD Axis I diagnoses, 29.5% presented with muscle disorders (group I), 7.9% with disk displacements (group II), and 39.1% with other joint disorders (group III). Headaches were present in 67.9% and awake and sleep bruxism in 30% and 33.4% of the population, respectively. Conclusion: The prevalence of signs and symptoms of TMD was high in this population, but with low disability; however, the proportion of patients in need of treatment was much lower.

Relationship between temporomandibular disorder symptoms signs and Burnout syndrome among dentistry students

“…Similarly, there is a female predisposition for TMD, the explanations of which are also based on similar emotional factors, in addition to hormonal factors 23 . Our results have shown decrease in ProDTMMulti scores along the years for females, however, they remained always higher as compared to males, which indicates that females have higher perception of TMD signs and symptoms 3,31 . ProDTMMulti points to self-perception with regard to TMD signs and symptoms 12,13 , being relevant for professionals when deciding the therapeutic approach.…”

“…Epidemiologic studies point that 75% of the population have had at least one TMD sign and 33% at least one symptom 1,2 . Stress and excessive work-load may be risk factors for TMD, which has high prevalence of signs and symptoms in the Brazilian population 3 . Major signs and symptoms associated to this condition are: jaw movement limitation, joint noises and pain on face muscles and/or pre-auricular region 4 .…”

Disk displacement, eccentric condylar position, osteoarthrosis – misnomers for variations of normality? Results and interpretations from an MRI study in two age cohorts

“…More recent investigations have corroborated the assumption that so-called anterior disc displacements are common in normal populations. For example, in a community sample of 1643 individuals in Brazil, the prevalence of disc displacements as diagnosed clinically with the RDC/TMD was around 8% [52]. Not unexpectedly, higher values are found among patients.…”

Efetividade da laserterapia de baixa intensidade em mulheres com DTM dolorosa em função da ansiedade, cortisol salivar e ciclo menstrual: ensaio clínico randomizado controlado duplo-cego

“…Diversos estudos mostraram maior prevalência de DTM para o gênero feminino (ROCHA; NARDELLI; RODRIGUES, 2002;FILLINGIM et al, 2009;GONÇALVES et al, 2010;SCHIMID-SCHWAP et al, 2013;MAZZETTO et al, 2014;PROGIANTE et al, 2015;FERREIRA et al, 2016). Na Universidade de Viena foram avaliados 502 voluntários e foi observada prevalência de DTM de 80% nas mulheres (SCHIMID-SCHWAP et al, 2013).…”

“…A dor na ATM foi o segundo sintoma mais comum encontrado e a prevalência foi estatisticamente maior em mulheres, quando comparada aos homens. Progiante et al (2015) avaliaram a prevalência das DTMs em uma amostra significativa da população brasileira em função dos diagnósticos obtidos pelo RDC/TMD. Os autores observaram maior prevalência das disfunções musculares, seguidas de artralgias, osteoartrose, deslocamento de disco e osteoartrite.…”
