Abstract

Abstract

Objectives: Does a complex intervention of oral hygiene advice (OHA) delivered with intra-oral scanner images, anti-gingivitis toothpaste and motivational reminders, improve oral health more than a standard of care control arm of fluoride toothpaste, with OHA without scanner images?

Methods: Adult participants with pre-existing gingivitis were randomised to intervention or control. Following enrolment, baseline and each subsequent visit (V) (3-weeks, V2; 3-months, V3; 6-months, V4) followed the same schedule. Bleeding on Probing (BOP) was assessed and Intra Oral Scan IOS(1) recorded. Plaque was disclosed, scored and re-scanned (IOS(2)). The intervention group received OHA with IOS images, control group receiving OHA without IOS images. Participants brushed with their allocated toothpaste (fluoride, control; anti-gingivitis, intervention), IOS(3) was recorded. Between visits participants brushed with their allocated toothpaste, intervention group received motivational reminders.

Results: BOP scores from baseline were significantly improved in the intervention group compared to control at all visits for all surfaces (pConclusion: A complex intervention comprising OHA delivered with IOS-images, anti-gingivitis toothpaste and motivational reminders improved gingival health more than existing standard of care-OHA together with a standard fluoride toothpaste over a 6-month period.

Clinical Significance Statement
Intra-oral scans (IOS) are now frequently used in general dental practice for a variety of purposes. IOS use, in combination with motivational texts and an anti-gingivitis toothpaste, could be further deployed to promote oral hygiene behaviour change in patients and improve gingival health, in a cost-effective manner.
