该研究的目的是比较含氟窝沟封闭剂（Helioseal F）与传统（简洁光固化白色封闭剂）窝沟封闭剂在年轻人中的固位和防龋能力。三位牙医在 59 名 18-20 岁成年人的 122 条第一和第二磨牙的裂隙上使用了密封剂材料。选择一百二十二颗非龋齿且未封闭的磨牙作为对照。使用以下标准评估牙齿：1 - 完全保留（FR），2 - 部分丢失（PL），3 - 完全丢失（TL）和4 - 腐烂（D）。所有牙齿均由两名对密封剂材料不知情的检查员在 3、6、12 和 24 个月时进行临床评估。通过卡方检验对数据进行统计分析。 3 个月后，72.1% 的密封剂完全保留，24 个月后，这一比例下降至 46.7%。密封剂的部分损失发生在3个月（15.6%）、6个月（26.2%）、12个月（27.9%）和24个月（27%）。 Helioseal F 的总损失量（第 3、6、12 和 24 个月分别为 16.4、19.7、18、23%）高于 Concise Light Cure White Sealant 的总损失量（分别为 8.2、9.8、11.5、18%）；这意味着 Helioseal F 的保留率低于简洁光固化白色密封剂。所有经过封闭剂处理的牙齿在第 3 个月和第 6 个月时均未检测到龋齿。 12 个月和 24 个月时，经过 Helioseal F 处理的牙齿的龋齿发生率为 11.5%，而经过简洁光固化白色封闭剂处理的牙齿的龋齿发生率为 0%。 24个月后所有接受窝沟封闭治疗的牙齿龋齿发生率分别为5.7%和25.4%。结果强调，在该样本中对年轻人应用窝沟封闭剂是预防窝沟龋的有效方法。
The aim of the study was to compare the fluoride-containing fissure sealants (Helioseal F) with the conventional (Concise Light Cure White Sealant) fissure sealants in their retention and caries-prevention capabilities in young population. Sealant materials were applied by three dentists on 122 fissures of first and second molars in 59 adults, 18-20 years of age. One hundred and twenty-two non-carious and unsealed molar teeth were selected as controls. The teeth were assessed using the following criteria: 1 - fully retained (FR), 2 - partially lost (PL), 3 - totally lost (TL) and 4 - decayed (D). All teeth were clinically assessed at 3, 6, 12 and 24 months by two examiners who were blinded to the sealant materials. Data were statistically analysed with chi-square tests. After 3 months 72.1% of sealants were fully retained, at 24 months this had dropped to 46.7%. The partial loss of sealants was at 3 months (15.6%), 6 months (26.2%), 12 months (27.9%) and 24 months (27%). The total loss of Helioseal F (16.4, 19.7, 18, 23% at 3rd, 6th, 12th and 24th months, respectively) was more than the total loss of Concise Light Cure White Sealant (8.2, 9.8, 11.5, 18%, respectively); meaning that the retention rate of Helioseal F was lower than for Concise Light Cure White Sealant. No caries was detected at 3rd and 6th months in all sealant-treated teeth. The incidence of caries in Helioseal F treated teeth at 12 and 24 months was 11.5% and 0% in Concise Light Cure White Sealant treated teeth. The incidence of caries in all fissure-sealant-treated-teeth after 24 months was 5.7 and 25.4% in control group. The results underline that the application of fissure sealants to young people in this sample is an effective method for the prevention of fissure caries.
