Purpose: To determine the incidence and distribution of enamel demineralisation (white spot lesions, WSL) adjacent to fixed orthodontic brackets in a low-caries population and to evaluate the value of pre-treatment bitewing radiographs in predicting such lesions. Material and methods: A group of 495 consecutive patients under the age of 19-years (mean 13 yrs) that were treated with fixed appliances during at least 6 months was included. Approximal enamel lesions were scored on bitewing radiographs exposed at onset and immediately after treatment and the incidence of WSL was registered clinically at de-bonding. Results: The incidence of WSL around brackets was 23% and mandibular premolars and cuspids and maxillary cuspids and lateral incisors were most frequently affected. The number of approximal enamel lesions at treatment onset were significantly correlated to WSL development during active treatment (r=0.35, p<0.001). When the onset presence of approximal enamel lesions (≥1) was used as predictor for enamel demineralisations at debonding, the odds ratio for becoming white spots during treatment was 5.6 (p<0.001), with a sensitivity of 0.74 and a specificity of 0.67. Conclusions: The orthodontic team should take pre-treatment bitewing radiographs into consideration when informing the patients on the risk of caries-related adverse effects following orthodontic treatment.
