Pit and fissure caries account for about 90% of caries in children and adolescents. Sealant application may be a preventive conservative approach. But it's still challenging to bolster the retention of the filled sealant and to chop back the microleakage.
Aim is to evaluate and compare the microleakage and shear bond strength (SBS) of three filled pit and fissure sealants (PFS) using a subpressure and adhesive system: an experimental analysis.
A total of 90 orthodontically extracted premolars were prepared for microleakage and SBS and divided according to materials and subgroups. Group I: resin-based filled PFS, group II: resin-modified glass ionomer-based filled PFS, and group III: giomer-based filled PFS. Subgroup 1: only sealant application, subgroup 2: subpressure application, and subgroup 3: adhesive system + subpressure application. Samples were subjected to thermocycling. Microleakage was assessed with a dye penetration method under a stereomicroscope, and SBS was assessed with a universal testing machine.
Unpaired -test and one-way analysis of variance (ANOVA) test were used for analysis. Significant when < 0.05. The SBS showed significant results for subpressure application and giomer-based filled PFS with < 0.05. The microleakages score differed significantly for the subpressure application group with < 0.05. Giomer-based filled PFS showed the least microleakage score.
This study concluded that giomer-based filled PFS showed statistically significant results. The subpressure technique significantly reduces microleakage and increases SBS.

窝沟龋约占儿童和青少年龋齿的90%。应用窝沟封闭剂可能是一种预防性保守方法。但提高封闭剂的保留率并减少微渗漏仍然具有挑战性。
旨在评估和比较三种使用负压和粘结系统的填充型窝沟封闭剂(PFS)的微渗漏和剪切粘结强度(SBS):一项实验分析。
总共制备了90颗正畸拔除的前磨牙用于微渗漏和SBS测试,并根据材料和亚组进行划分。第一组:树脂基填充型PFS,第二组:树脂改性玻璃离子基填充型PFS,第三组:聚酸改性复合树脂基填充型PFS。亚组1:仅应用封闭剂,亚组2:应用负压,亚组3:粘结系统+应用负压。样本进行热循环处理。在体视显微镜下用染料渗透法评估微渗漏,用万能试验机评估SBS。
采用非配对t检验和单因素方差分析(ANOVA)进行分析。P<0.05时有统计学意义。对于应用负压和聚酸改性复合树脂基填充型PFS,SBS显示出显著结果,P<0.05。应用负压组的微渗漏评分差异有统计学意义,P<0.05。聚酸改性复合树脂基填充型PFS的微渗漏评分最低。
本研究得出结论,聚酸改性复合树脂基填充型PFS显示出统计学显著结果。负压技术显著降低微渗漏并提高SBS。
