Results of a 3-year oral hygiene programme, including amine fluoride products, in patients treated with fixed orthodontic appliances.

This paper reports the results of a 3-year study on children treated with fixed orthodontic appliances. They were all regularly instructed in oral hygiene maintenance and used a standardized fluoride-free toothpaste during the course of the study. The patients were divided into three groups. Groups one and two, respectively, had a fluoride gel and fluoride fluid (Elmex amine fluoride products, GABA International Ltd, Basle, Switzerland) applied. Group three used only the toothpaste supplied, had oral hygiene instruction, but not topical applications. Caries increments were lowest and gingival health best in the two groups using amine fluorides, especially the gel group.
