The retention of a self-polymerized fissure sealant applied after twenty seconds etching time was evaluated after three years. From the original 100 molars that were sealed, seventy-one teeth with 105 sites were available. The sealants were totally retained in 91 percent of the cases, after three years. The findings demonstrate that the retention rates of fissure sealants using twenty seconds etching time are comparable to those reported with the more conventional sixty seconds.
在蚀刻20秒后应用的自聚合窝沟封闭剂在三年后的保留情况进行了评估。在最初密封的100颗磨牙中，有71颗牙齿的105个部位可供评估。三年后，在91%的病例中封闭剂完全保留。研究结果表明，蚀刻20秒的窝沟封闭剂的保留率与更传统的60秒蚀刻所报告的保留率相当。
