ObjectivesTo assess the association between aspects of the dentist‐patient relationship at age 65 and Oral Impacts on Daily Performances (OIDP) at ages 65 and 70 and to examine whether dental avoidance behaviours play a role in explaining that association.BackgroundInformation about the quality of the dentist‐patient relationship is important for dental care provision and healthy ageing.MethodSecondary data analysis of a cohort study of Norwegians born in 1942. The participation rate in 2007 (age 65) and 2012 (age 70) was, respectively, 58.0% (n = 4211) and 54.5% (n = 3733). A total of 70.0% (n = 2947) of the baseline participants responded in 2012. Dentist‐patient relationship aspects were assessed in terms of communication with the dentist, satisfaction with dental care, unpleasant experiences and changes of dentist. Generalised Estimating Equations (GEEs) were used to account for repeated measurements.ResultsPrevalence of oral impacts (OIDP) was 29.0% in 2007 and 28.4% in 2012. Participants who received communication on oral hygiene during dental visits had a higher likelihood, whereas participants who reported satisfaction with dental care, no unpleasant experience and did not change dentist had a lower likelihood of reporting oral impacts over these 5 years. Corresponding odds ratios were: 1.2 (95% CI 1.0–1.5), 0.4 (95% CI 0.3–0.5), 0.6 (95% CI 0.5–0.7) and 0.5 (95% CI 0.3–0.6). Associations between dentist‐patient relationship aspects and OIDP remained unchanged after adjustment for avoidance behaviours.ConclusionTraining dentists in relationship skills might improve social interaction with patients and the oral health–related quality of life of older people in Norway.
