Dietary analysis and nutritional counselling for caries prevention in dental practise: a pilot study

Abstract

Background: Dental practitioners agree that dietary counselling is essential for caries prevention; however, they provide advice infrequently due to a lack of confidence and competence. This study aimed to improve practises through an online training module exploring the use of a brief counselling method, and a diet assessment of caries risk form.

Methods: Dental practitioners (N = 41) completed a survey on current practises and confidence in providing dietary advice, followed by an online training module. Ten practitioners were involved in recruiting patients, eliciting a diet assessment of caries risk, and using brief counselling techniques with these patients. Patients were followed up at 6 months for a risk assessment review. Dental practitioners also completed a 6-month follow-up survey exploring changes in confidence and perceived barriers.

Results: Dental hygienists' confidence improved significantly following the intervention (P < 0.025). Patients showed a significant reduction in high-risk behaviour pertaining to quantity and timing of sugar intake, and significant trends in improvement of behaviours relating to frequency, exposure time and drinking style (P < 0.05).

Conclusions: It appears that a simple online learning module can improve hygienists' confidence in dietary advice provision, and have a positive impact on patient behaviour change, within a relatively short time-frame.
