This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Modern restorative dentistry relies on generating an immediate and lasting bond to the underlying enamel and dentin. Current adhesive systems involve etching the tooth with an acid solution followed by washing, application of a bonding agent, and finally application of a restorative material. Although these measures are effective, they also have several disadvantages. Each step requires time, and if the etching and priming procedures are carried out in full they add to the treatment time considerably. In addition, there is a risk of contamination of the etched or primed surface by saliva, blood, or water. If this happens, the tooth surface has to be cleaned and the etching and priming procedure has to be repeated. It is desirable to simplify the adhesive process for the dentist. Newer generation adhesive systems have adopted a strategy to use low pH resin primers to simultaneously demineralize and penetrate the mineralized tooth surface. The purpose of this clinical trial is to compare the clinical performance of a single component Self-Etching adhesive (1P-SEA) with a conventional adhesive in non-carious cervical lesions.

这个子项目是利用由NIH/NCRR资助的中心拨款提供的资源的许多研究子项目之一。子项目和调查员(PI)可能从另一个NIH来源获得了主要资金，因此可能会出现在其他CRISE条目中。列出的机构是针对中心的，而不一定是针对调查员的机构。现代修复性牙科依赖于与底层牙釉质和牙本质产生直接和持久的联系。目前的粘接系统包括用酸性溶液酸蚀牙齿，然后清洗，使用粘结剂，最后使用修复材料。虽然这些措施是有效的，但它们也有几个缺点。每一步都需要时间，如果完全进行蚀刻和底漆程序，就会大大增加处理时间。此外，蚀刻或底漆表面有被唾液、血液或水污染的风险。如果发生这种情况，则必须清洁牙齿表面，并且必须重复蚀刻和底漆程序。希望简化牙医的粘合过程。新一代粘接系统采用了一种策略，使用低pH树脂底漆同时脱矿和渗透矿化的牙齿表面。本临床试验的目的是比较单组分自酸蚀粘接剂(1P-SEA)和传统粘接剂在非龋性宫颈病变中的临床表现。
