The role of illness beliefs and coping in the adjustment to dentine hypersensitivity.

Objective: Dentine hypersensitivity is a common oral health problem, however, there has been little research on how people cope with this condition. This study aimed to quantify the effects of illness beliefs and coping strategies on the health outcomes of individuals with dentine hypersensitivity.

Methods: Participants were purposively sampled from students and staff in one large UK University and 101 self-diagnosed dentine hypersensitivity sufferers participated in the longitudinal study. Participants were required to complete questionnaires which assessed health anxiety, specific illness beliefs (control, consequences, illness coherence, timeline perspectives and emotional representations), coping strategies (passive and active coping) and oral health-related and health-related quality of life (OHRQoL and HRQoL) at baseline and 1 month follow-up.

Results: Over half of the participants (N = 56) experienced sensations in their teeth on a daily basis and the majority had experienced dentine hypersensitivity for at least 1 year (N = 87). Structural equation modelling indicated that predictors of OHRQoL and HRQoL impacts at follow-up were frequency of sensations, low levels of illness coherence, negative emotional representations, greater health anxiety and use of passive coping strategies at baseline.

Conclusions: Illness beliefs and coping strategies predict oral and health-related quality of life outcomes in people with dentine hypersensitivity.
