目的
探讨含氟量为1450 ppm 的牙膏再矿化根龋的效果。
方法
采用随机双盲对照设计,受试者被随机分为不含氟牙膏组(对照组)和1450 ppm 含氟牙膏组(实验组)。 在基线、3 个月和6 个月时检查根面龋的硬度、病损范围、菌斑指数,用电阻抗(ECM)仪测量根面龋的电阻值。数据用SPSS 13.0 统计软件包进行统计分析。
结果
179 名受试者参加研究(实验组89 名,对照组90 名),156 名(87.6%)完成整个研究。 研究结束时,实验组根面龋的龈缘距离高于对照组[(0.34±0.42) mm 和(0.19 ± 0.36) mm,P=0.021)];菌斑指数低于对照组(1.25 ± 0.78 和1.56 ± 0.77,P=0.015);Lg ECM 值高于对照组(3.52 ± 0.54 和3.24 ± 0.40,P <0.001);根面龋变硬的数量百分比高于对照组(34.18%和15.58%,P=0.027)。
结论
含氟量为1450 ppm 的牙膏可以有效地再矿化根面龋。
Objective
The objective of this longitudinal study was to investigate the effects of 1450 ppm fluoride dentifrice on the remineralization of root caries.
Methods
Qualified adults satisfied with inclusion and exclusion criteria were applied to this randomized double-blinded clinical trial. The subjects were randomly assigned to non-fluoride dentifrice group (control group) and 1450 ppm fluoride dentifrice group (experimental group). Clinical criteria including hardness, area, plaque index and electrical caries monitor (ECM) were used to evaluate root caries in subjects at baseline, 3 months and 6 months. All data were analyzed using SPSS 13.0 software.
Results
Total of 179 subjects were included in the present study (89 in experimental group and 90 in control group), among which 156 subjects (87.6%) completed the entire study. At the end of the study, root caries in the experimental group showed higher gingival distance than those in the control group [(0.34 ± 0.42) mm and (0.19 ±0.36) mm, P=0.021], less plaque index (1.25±0.78 and 1.56±0.77, P=0.015) and higher Lg ECM(3.52±0.54 and 3.24±0.40, P <0.001). More root caries in the experimental group became hard than those in the control group (34.18% and 15.58%, respectively, P=0.027).
Conclusions
Dentifrice containing 1450 ppm fluoride is effective on the remineralization of root caries in adults.
