研究了不同树脂密封剂对拔除的人类臼齿的牙窝和牙缝的渗透情况。结果表明，预处理前的预防和涂上密封剂只清洁了牙尖斜面，凹痕和裂隙经常充满碎片。尽管采取了不同的预防措施，情况依然如此。在对咬合部位进行酸性处理并放置树脂后，通过牙坑和牙缝进行的牙齿切片显示，浅型牙缝被填充，而深型和收缩型牙缝未被填充。裂缝中的残留物质、空气夹持和裂缝的几何形状限制了密封胶的渗透。没有建立满意的临床方法来清洁牙窝和牙裂，预防性牙切开术的尝试导致了与预备相关的残余牙裂。虽然这些制剂中填充了密封胶，但没有残留的裂缝。尽管存在这样的变数，但已报告的临床成功还是发生了，我们的观察结果不应谴责这种有效的预防措施。
An investigation was conducted into the penetration of different resin sealants into the pits and fissures of extracted molariform teeth of humans. The results showed that prophylaxis before conditioning and sealant placement only cleaned the cuspal inclined planes and that pits and fissures often remained filled with debris. This was true despite different prophylactic measures. After acidic conditioning of the occlusal site and resin placement, sections of teeth through pits and fissures showed that shallow types of fissures were filled but that deep and constrictive types were not. Residual material in the fissure, air entrapment, and fissure geometry contributed to a limiting of the sealant penetration. No satisfactory clinical means was established to clean the pits and fissures, and attempts at prophylactic odontotomy resulted in residual fissures associated with the preparations. Although the preparations were filled with sealant, the residual fissures were not. Reported clinical successes have occurred despite such variables, and our observations should not serve to condemn this effective preventive measure.
