Abstract

Background: Pain in the temporomandibular region is a main complaint causing disability and distress among temporomandibular disorders sufferers.

Objectives: The aim of the study was, over an 11-year follow-up on Finnish adult population, to investigate the prevalence of clinically assessed pain-related temporomandibular disorder (TMD) signs, i.e. temporomandibular joint (TMJ) and masticatory muscles (MM) pain on palpation, and their association with sociodemographic background and denture status.

Methods: The data were based on the nationally representative Finnish Health 2000 and Health 2011 Surveys (BRIF8901). The sample comprised 1210 adults who underwent clinical oral examinations including TMD signs assessment. Statistical evaluations included chi-square tests and logistic regressions.

Results: The prevalence of palpatory MM pain decreased from 9.5% at baseline to 4.6% in the follow-up. Cross-sectionally, presence of palpatory MM pain significantly associated with gender (p < .001, p = .002) and educational level (p < .001, p = .001) in both years, and with age (p = .006) and denture status (p = .022) at baseline. The prevalence of palpatory TMJ pain increased from 2.1% at baseline to 3.5% in the follow-up. Presence of palpatory TMJ pain significantly associated with gender in both years (p = .012, p = .032). Female gender, lower education and palpatory MM pain at baseline predicted palpatory MM pain in the follow-up.

Conclusion: Palpatory MM pain is relatively prevalent in adults, yet with a favourable prognosis. Women and people with low education are more susceptible groups. Previous experience of palpatory MM pain increases the risk of exhibiting it later in life.
