Purpose:
To determine the evolution of toothbrushing frequency and use of fluoridetoothpaste in the FDI-Unilever partnership Live.Learn.Laugh. phase 2 programme using a self-reported questionnaire.
Methods:
The study was conducted in 23 countries. The key focus of this partnership was to educate people about the benefits of twice-daily brushing with fluoride toothpaste and to support people in adopting this important oral health behaviour. The partnership offers a choice of four project options to the local partnership team of the National Dental Association and local Unilever-operating companies. A self-report questionnaire was used in all participating subjects in local projects to evaluate the brushing frequency, the brushing timing and the use of fluoride toothpaste.
Results:
After implementation of the project interventions, a clear improvement in the reported frequency of brushing twice a day, regardless of the type of project, was observed. Subjects also increased day and night brushing and the use of fluoride toothpaste.
Conclusion:
The strategy of using mothers to increase healthy behaviours in oral health achieved the greatest increase in twice-daily toothbrushing, followed by the intervention in schools.
