Three groups of men aged 19 to 22 years were examined. Group A was regarded as control, group B was treated topically with stannous fluoride solution every 6 months, group C received a gel for brushing once a week. All the subjects were re-examined after 6, 12, 18, 24, 30 and 36 months and DMFS scores were analysed. In the end of the trial 639 teeth from 213 participants were evaluated in vivo for enamel solubility rates by the CRT test. After three years of treatment both examinations disclosed that the gel was more effective in dental caries inhibition and reduction of the enamel solubility in acids, than stannous fluoride solution.
对三组年龄在19至22岁的男性进行了检查。A组作为对照组，B组每6个月用氟化亚锡溶液进行局部治疗，C组每周接受一次刷牙用凝胶。所有受试者在6、12、18、24、30和36个月后重新接受检查，并分析DMFS评分。在试验结束时，通过CRT试验对213名参与者的639颗牙齿进行了体内釉质溶解度评估。经过三年的治疗，两项检查均显示，该凝胶在抑制龋齿和降低釉质在酸中的溶解度方面比氟化亚锡溶液更有效。
