| Popis: | Decalcification and caries during orthodontic treatment still remains a problem. A method to protect the susceptible area beneath and adjacent to bonded attachments, independent of patient compliance, would be extremely beneficial. A clinical trial was performed using a dual-cured lightly filled BIS-GMA fluoride-releasing sealant. The barrier effect of this material on white spot formation, gingival irritation, and plaque accumulation during fixed orthodontic therapy was examined. Twenty patients with a total of 225 metal brackets placed on anterior teeth participated in this study. Brackets were placed in both arches in a conventional manner with a chemically cured, unfilled bonding resin; 112 teeth (every other tooth) received the barrier material after bracket placement, while the remaining 113 teeth served as controls. Intraoral photographic slides were taken before and after treatment and were evaluated blindly by 7 observers for white spot formation. Gingival and plaque indexes were recorded initially and consecutively every 6 months. Observation time ranged from 5 to 18 months. The results of this prospective clinical study indicated that there was no significant difference (P >.05) between the decalcification rates of the treatment or control groups. Likewise there was no added benefit with respect to plaque accumulation or gingival irritation. |
