本研究的目的是确定48个月的预防性牙科计划对居住在最佳氟化区域的城市老年非制度化人群的根龋发病率的影响。466名参与者在基线时被随机分配到三组中的一组。A组（对照组）：171名受试者每天使用安慰剂漱口水; B组：147名受试者接受局部APF凝胶（1.2% F）的半年应用，每天使用安慰剂漱口水; C组：148名受试者每天使用氟化漱口水，ACT（0.05% F）。在基线时，记录有风险的表面数量，以及腐烂和填充的表面。此外，48个月后，确定逆转和新病变的数量，并计算增量DMFS。数据采用协方差分析。增量DMFS为：A/0.91，B/0.27，C=0.26。B组和C组的DMFS增量显著低于A组（P<0.05）。C组逆转病灶数（1.53 ± 2.03）个，明显多于A组（1.11 ± 1.74）个和B组（1.01 ± 1.86）个（P<0.05）。B组新发病灶数（1.36 ± 2.00）明显少于A组（1.99 ± 2.65）（P<0.05）。每天使用含氟漱口水显著增加了逆转病变的数量。
The purpose of this study was to determine the effect of a 48‐month preventive dental program on the incidence of root caries in an urban, geriatric, noninstitutionalized population residing in an optimally fluoridated area. The 466 participants were randomly assigned to one of three groups at baseline. Group A (control): 171 subjects using a placebo mouth rinse daily; group B: 147 subjects receiving semiannual applications of a topical APF gel (1.2% F) with the daily use of a placebo mouthrinse; group C: 148 subjects using a fluoridated mouthrinse daily, ACT (0.05% F). At baseline, the numbers of surf aces at risk, and decayed and filled surfaces were recorded. After 48 months, in addition, the number of reversed and new lesions were determined, and the incremental DMFS calculated. The data were analyzed by ANCOVA. The incremental DMFS were: A/0.91, B/0.27, C=0.26. The incremental DMFS in groups B and C were significantly lower than in group A (P<.05). The number of reversed lesions in group C (1.53 ± 2.03) was significantly greater than in group A (1.11 ± 1.74) and group B (1.01 ± 1.86) (P<.05). The number of new lesions in group B (1.36 ± 2.00) was significantly less than in group A (1.99 ± 2.65) (P<.05). The daily use of the fluoride mouthrinse significantly increased the number of reversed lesions.
