简要总结
The aim of this 2-armed, parallel, randomised, controlled trial is to assess the effect of different ways of applying fluoride to teeth on the formation of white spots (enamel demineralisation), during orthodontic treatment with fixed metal braces, in children and adolescents.
详细描述
One of the most common side-effects and risks of orthodontic treatment with fixed (metal) braces is damage to the outer surface (enamel) of the teeth. This damage can take the form of white or brown spots on the teeth (white spot lesions; WSLs) or if severe, holes in the teeth that need a filling.
The aims of this study are to find out the best way of preventing damage to the teeth of children and adolescents who are under going orthodontic treatment with fixed (metal) braces.
The participants will be 130 children, aged 11-16 years old, inclusive. The participants will be split into two groups using a process called randomisation. The treatments will be standard fluoride toothpaste (Colgate) and either:
- Fluoride mouth wash (Fluorigard) or
- Tooth Mousse Plus
The participants' teeth will be checked at every visit and the brace adjusted. Photographs of the participants' teeth will be taken very 3 months to see if any of the teeth have been damaged. The participants will be asked about the impact of their teeth on their life. Participants and parents will be asked about the impact of any white spots that form on the participants' teeth during the treatment with fixed (metal) braces.

结局指标
主要结局
New white spot lesions (WSLs)
时间窗: Through to study completion, an average of 2 years
The incidence of new demineralisation (WSLs), developing on the anterior teeth during fixed orthodontic treatment assessed from white light and quantitative light-induced fluorescence (QLF) images, will be measured. Numerical scale 0 - unlikely to be more than 100. Higher score is worse.
