摘要
先前的研究表明,局部使用氟清漆Duraphat可以减少龋齿的发生率。本研究的目的是比较含有1.80%氟(F)的新型氟清漆(Carex)与含有2.26%氟(F)的Duraphat的抑龋效果。获得了沃斯牙科保健区(低F区)495名10-12岁儿童的监护人的知情同意。孩子们被随机分为两组。一组患者每6个月使用Duraphat (n = 206),另一组患者使用Carex (n = 189)。伦理考虑排除了安慰剂清漆的使用。所有参加者每年均接受牙科检查,包括一对后咬牙x光片及必要的牙科护理。一位训练有素的审查员盲目地解读咬翼x光片。Duraphat组24个后近似面2年净DFS增量为1.79 (s = 3.12), Carex组为1.53 (s = 2.92),差异无统计学意义(P > 0.40)。由此看来,苔牙和杜拉法对后牙表面的防龋效果大致相同。
[Two-year trial of the fluoride-containing varnishes Duraphat and Carex].
Previous studies have shown that topical application of the fluoride varnish Duraphat reduces caries incidence. The aim of the present study was to compare the caries inhibiting effect of a new fluoride varnish (Carex) containing 1.80% fluoride (F) with that of Duraphat (2.26%F). Informed consent was obtained from the guardians of 495 10-12-years-olds in Voss Dental Health District (low F area). The children were randomly allocated to two groups. One group of subjects received six-monthly applications of Duraphat (n = 206), the other Carex (n = 189). Ethical considerations precluded the use of a placebo varnish. All participants received dental examinations including one pair of posterior bitewing radiographs and necessary dental care annually. One trained examiner interpreted bitewing radiographs blindly. Total mean 2-year net DFS increment for 24 posterior approximal surfaces was 1.79 (s = 3.12) in the Duraphat group and 1.53 (s = 2.92) in the Carex group, a difference which was non-significant (P greater than 0.40). Thus it seems that Carex and Duraphat have approximately the same caries-preventive effect on posterior approximal surfaces.
