Abstract

Studies of the caries susceptibility of stripped proximal surfaces have produced some what varying results. We aimed in this study to highlight on the effect of anterior interproximal enamel reduction on caries susceptibility and to evaluate if topical application of fluoride is needed or not. This study was conducted on 28 patients with mean age 13.3 + 0.74 years. They were all caries free with good gingival condition. They were divided into 4 equal groups; group 1: had no orthodontic treatment, group 2: had fixed orthodontic treatment without interproximal reduction, group 3: had fixed orthodontic treatment after anterior interproximal reduction and group 4: had fixed orthodontic treatment after anterior interproximal reduction followed by topical application of sodium fluoride. They were all instructed to follow proper oral hygiene methods. It was found that there was no caries development in the four groups till the end of the 3 years follow up period. It was concluded that well controlled interproximal enamel reduction may not be a caries risk factor
