The application of Duraphat in the prevention of secondary caries after restoration in primary teeth

目的:观察评估多乐氟(Duraphat)用于儿童乳牙龋病充填后预防和降低继发龋的治疗效果。方法:选择4~6岁乳磨牙龋病充填修复后,实验组204颗患牙行全口牙列涂多乐氟保护漆,每3~6个月定期复查并涂氟保护漆;对照组198颗患牙则充填修复完成后定期随访复查。结果:1年后实验组继发龋33颗;对照组继发龋69颗;12个月和24个月继发龋发病率实验组与对照组比较,两组间差异具有统计学意义(P<0.05)。结论:多乐氟(Duraphat)能有效预防儿童乳牙龋病充填后继发龋的发生,改善口腔环境,值得临床推广。
