Four year Evaluation of Proximal Resin Infiltration in Adolescents

Resin infiltration of proximal lesions is a new approach to stopping caries progression. Therefore, the aim of the present study was to evaluate four-year efficacy of proximal infiltrates in adolescents. In ten adolescents, a total of 21 proximal infiltrates (ICON® (DMG, Germany) were applied to initial proximal lesions of permanent incisors and premolars according to the manufacturer's instruction. The clinical quality of resin infiltration was assessed at 1 week, 1, 2, 3 and 4 years after the treatment and the evaluation of the therapeutic effect was analyzed by radiographs. Ten patients were followed up clinically for four years. The majority of the infiltrated lesions were located on permanent incisors. Teeth which were proximally infiltrated did not exhibit dental plaque and gingival bleeding in most cases. At annual recalls, plaque scores remained constant. The gingival status remained steady and no differences in tooth shape and contour were detected. Discoloration was detected in four teeth (19%) in 1st year recall and was constant at annual intervals. The radiographic evaluation of the bitewing radiographs showed no progression in 21 lesions (100%) from baseline to the 4-year recall. Overall oral hygiene of the patients was satisfactory. In conclusion, proximal infiltration is an effective prophylactic measure in adolescents.
