A randomised controlled trial to investigate the remineralising potential of Tooth Mousse™ in orthodontic patients.

OBJECTIVE: To investigate the remineralisation of enamel subsurface lesions treated with fluoride toothpaste (1450 ppm) or a combination of fluoride toothpaste in addition to Tooth Mousse™.

DESIGN: An in situ, cross-over, randomised controlled trial.

SETTING: Orthodontic department at Liverpool University Dental Hospital, UK.

PARTICIPANTS: Twelve patients receiving fixed orthodontic treatment.

METHODS: Demineralised subsurface enamel lesions were placed in a carrier and attached onto a fixed orthodontic appliance. Interventions were either standard fluoride toothpaste or CPP-ACP paste (Tooth Mousse™) in addition to the fluoride toothpaste. Participants received both interventions in a randomised order. Transverse microradiography analysis was used to compare lesion mineral content profiles.

RESULTS: Mineral loss was reduced by 15.4 and 24.6% between the fluoride and CPP-ACP groups, respectively (p = 0.023). Lesion depth was reduced by 1.6 and 11.1% between the fluoride and CPP-ACP groups, respectively (p = 0.037). Lesion width was reduced by 4.5 and 15.3% between the fluoride and CPP-ACP groups, respectively (p = 0.015).

CONCLUSIONS: Remineralisation occurred regardless of treatment group allocation. However, the addition of Tooth Mousse™ resulted in a significantly increased remineralisation effect, compared to fluoride alone. Tooth Mousse™ may be beneficial for patients undergoing orthodontic treatment who are at high risk of demineralisation.
