Associations between social and general health factors and symptoms related to temporomandibular disorders and bruxism in a population of 50‐year‐old subjects

Abstract

The aim of this epidemiological study was to examine associations between temporomandibular (TMD)-related problems and variables from three domains: (1) socio-economic attributes, (2) general health and health-related lifestyle, and (3) dental attitudes and behaviors. The overall response rate to a questionnaire mailed to the total population of 50-year-old subjects in two Swedish counties (8,888 individuals) was 71%. Among the 53 questions in the questionnaire, those related to social, general health, and health-related factors were used as independent variables in logistic regression models. Three TMD-related symptoms and reported bruxism were used as dependent variables. Impaired general health was the strongest risk factor for reported TMD symptoms. Along with female gender and dissatisfaction with dental care, impaired general health was significantly associated with all three TMD symptoms. A few more factors were associated with pain from the TMJ only. In comparison, reported bruxism showed more significant associations with the independent variables. In addition to the variables associated with TMD symptoms, being single, college/university education, and daily tobacco use were also significantly correlated with bruxism. Besides female gender, impaired general health, dissatisfaction with dental care, and a few social and health-related factors demonstrated significant associations with TMD symptoms and reported bruxism.

Ahlberg et al, 2005;Johansson et al, 2004;Lavigne et al, 1997;Molina et al, 2001;Ohayon et al, 2001), with a more detailed sleep laboratory examination only in the study of Lavigne et al (1997), albeit only on 15 bruxing subjects. Using questionnaires may cause difficulties in defining the actual prevalence of bruxism: It may be even more common among populations than surveys It is commonly agreed that sleep bruxism, defined as a stereotyped movement disorder occurring during sleep and characterized by tooth grinding and/or clenching, is in normal subjects detected in about 8% of the adult population (Lavigne, Manzini, & Kato, 2005) The prevalence for bruxism in our study is within the range, as also reported earlier (Hublin et al, 1998).…”

“…A Swedish cross-sectional study among 50-year-old males and females, based on a questionnaire (n = 6,343) and clinical examinations (n = 941) for validating and qualifying responses, showed a significant association in a multivariate model (with many covariates) between self-reported bruxism and daily tobacco use (either cigarette smoking or smokeless tobacco; Johansson et al, 2004). No difference in the prevalence of bruxism was found by tobacco use status prior to adjustment for covariates, which is opposite to our findings.…”

Disc derangements of the temporomandibular joint

“…These patients have their daily life much affected because of pain and impaired mandibular function. Recent studies have indicated that pain in the TMJ area and impaired TMJ function, besides the effect on eating/chewing, has a direct effect on enjoyment of life, mood and relationships 20,21 . The management of these patients therefore ought to have high priority but, because of uncertainty about diagnosis and lack of outcome research evidence, there has been hesitation about how to treat them.…”
