Abstract

Objectives: Poor oral hygiene can have an adverse effect on quality of life. School-based interventions can establish positive behaviours that reduce the likelihood of dental caries later in life. The Brush Day & Night programme aims to encourage good oral health behaviour and improve oral health and quality-of-life outcomes. In this article, we report the effect of the programme on well-being and oral hygiene measured by plaque levels at 3, 8, and 24 weeks and dental caries at 24 weeks after programme start date.

Methods: This was a superiority cluster randomised trial of children 6-12 years of age from Indonesia (N = 2021) and Nigeria (N = 2104). All children were provided with toothpaste and a toothbrush. Children in the intervention group received the 21-day Brush Day & Night programme, whereas those in the control group did not. Children completed a questionnaire addressing the objectives at all time points. Their oral hygiene was assessed using the Oral Hygiene Index-Simplified (OHI-S). Additionally, at baseline and 24 weeks their caries status was recorded using the decayed, missing, and filled teeth (DMFT) index.

Results: In Indonesia, after participation in the programme children demonstrated a 45% increased probability of no worsening in the occurrence of decayed, missing, or filled teeth. In Nigeria, children had a 71% higher probability of having confidence in their smile and the proportion of children with good oral hygiene doubled from 40% to 80% at 24 weeks.

Conclusions: The Brush Day & Night programme was successful in improving well-being and oral hygiene in children in Nigeria and reduced the likelihood of worsening in the occurrence of decayed, missing, or filled teeth in children in Indonesia.
