ABSTRACT
The objectives of this study were to test the hypothesis that self-reported TMJ clicking sounds in adolescents are positively associated with non-specific somatic symptoms, self-perception of body image and care-seeking behaviour. A cross-sectional study was carried out in 353 young adolescents (48·4% females) recruited from community (N = 272) and orthodontic clinic (N = 81) settings. Assessments included self-reported TMJ clicking, non-specific physical symptoms, body image concerns and for the clinic sample only, the source of motivation for treatment. TMJ sounds were self-reported by 19% of the sample and were associated with higher scores for non-specific physical symptoms and body image concerns (P < 0·001). Adolescents who were self-motivated to seek orthodontic treatment had greater scores for non-specific physical symptoms, more body image concerns and tended to report TMJ sounds more often (26·3% and 7·7% respectively; P = 0·41) than those who were solely parent/family-motivated to seek treatment. Self-reported TMJ sounds in adolescents were associated with a propensity to somatisation and concerns with body image. Care-seeking adolescents have greater non-specific physical symptoms and body image concerns and tend to report more frequent TMJ sounds.
