封闭龋齿裂隙被认为是阻止龋齿过程的适当治疗选择。然而，很少有资料是关于封闭的咬合空洞牙本质病变。在该体外研究中检验的假设是，当使用树脂时，空化和良好密封的裂缝之间的微渗漏和密封剂渗透深度没有差异。80颗磨牙，每一个咬合空洞牙本质病变，根据5个实验方案进行治疗，并与对照组的密封健全磨牙进行比较。在实验组中，以各种方式放置有粘合剂和没有粘合剂的裂缝封闭剂。对所有牙齿进行切片，并对微渗漏和密封剂渗透到裂隙中进行评价。封闭龋沟的微渗漏和封闭剂渗透深度均显著高于健全龋沟。无论是使用粘合剂，也不影响其中间固化的微渗漏分数和密封剂的渗透能力。
Sealing caries fissures is considered an appropriate treatment option for arresting the caries process. However, little information is available regarding the sealing of occlusal cavitated dentin lesions. The hypothesis tested in this in vitro study was that no difference in microleakage and sealant penetration depth exists between cavitated and sound sealed fissures when a resin is used. Eighty molars, each with an occlusal cavitated dentin lesion, were treated according to 5 experimental protocols and compared with a control group of sealed sound molars. In the experimental groups, fissure sealants were placed with and without an adhesive, and in various ways. All teeth were sectioned, and microleakage and sealant penetration into the fissure were evaluated. Sealed caries fissures showed significantly more microleakage and insufficient sealant penetration depth than sound fissures. Neither the use of an adhesive nor its intermediate curing influenced the microleakage score and the penetration ability of sealants.
