The aim of this study was to assess the effect of the Er:YAG laser on the clinical success of a hydrophilic fissure sealant over 12 months.
This study was conducted on 132 permanent first molars from 44 (19 girls and 25 boys) patients aged 7-11 years. The teeth were divided into three groups. The first group (Group A-control) of teeth were etched with phosphoric acid, the second group of teeth (Group L) were etched with an Er:YAG laser, and the third group of teeth (Group A+L) were etched with both the Er:YAG laser and phosphoric acid. Clinical evaluations were performed at baseline and at 3-, 6-, 9- and 12-month follow-up visits. The data were analyzed with Pearson chi-square tests, Cochran Q tests and Kaplan-Meier analysis.
At the end of the 12 months, total retention rates were 72.7%, 59.1%, and 65.9% in the acid group, the laser group and the laser and acid group, respectively. Although there was no statistically significant difference between group retention rates (p>0.05), the lowest retention rate was found in the laser group at the end of the 12-month follow-up period. No new caries were observed in any group during the study period.
Etching with the Er:YAG laser, phosphoric acid or a combination of both methods provided similar results for the clinical success of hydrophilic based fissure sealant.
本研究旨在评估铒激光对亲水性窝沟封闭剂12个月临床成功率的影响。
本研究对44名（19名女孩和25名男孩）7至11岁患者的132颗恒牙第一磨牙进行。将牙齿分为三组。第一组牙齿（A组-对照组）用磷酸酸蚀，第二组牙齿（L组）用铒激光酸蚀，第三组牙齿（A+L组）先用铒激光酸蚀，再用磷酸酸蚀。在基线以及3、6、9和12个月的随访时进行临床评估。数据采用Pearson卡方检验、Cochran Q检验和Kaplan-Meier分析。
12个月结束时，酸蚀组、激光组和激光与酸蚀联合组的总保留率分别为72.7%、59.1%和65.9%。尽管组间保留率无统计学显著差异（p>0.05），但在12个月随访期结束时，激光组的保留率最低。在研究期间，任何组均未观察到新龋。
用铒激光、磷酸酸蚀或两种方法联合酸蚀对亲水性窝沟封闭剂的临床成功率产生相似的结果。
