Regular dental attendance and periodontal health knowledge: A cross-sectional survey

To explore dental clinics' performance on periodontal education by comparing knowledge about periodontal health of regular and inconsistent dental attenders.

A population-based study with a cross-sectional design was performed in Galicia (Northwestern Spain). Participants were randomly selected from 16 different areas and a questionnaire applied face-to-face. The survey included items on socio-demographic features, habits and routines, periodontal status and periodontal health knowledge. Participants were grouped according to the median of overall knowledge, and a logistic regression analysis was performed to explore the relationship between good periodontal knowledge and frequency of dental visits.

A total of 8,206 individuals were invited to enter the study, and 3,553 of them accepted the invitation (43.3%). Most participants (59.3%; n = 1,945) fit within the regular dental attenders' group. Younger women holding a university degree and visiting their dentist regularly elicited higher knowledge about periodontal health. Regular use of dental services increased the chances of being in the higher knowledge group (OR: 1.67; 95% CI: 1.40-2.00).

Reported regular dental attendance is related to periodontal health knowledge. Specific interventions for promoting tailored patient education on periodontal topics during routine dental visits may have a positive effect on laypersons' knowledge about periodontal health.
