SELF-ETCH BOND AGENT IN THE RESTORATION OF NON-CARIOUS CERVICAL LESIONS

本子项目是利用由NIH/NCRR资助的中心赠款提供的资源的众多研究子项目之一。子项目和研究者（PI）可能已经从另一个NIH来源获得了主要资金，因此可以在其他CRISP条目中表示。列出的机构是中心的，不一定是研究者的机构。现代恢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。目前的粘合剂系统包括用酸溶液蚀刻牙齿，然后清洗，应用粘合剂，最后应用修复材料。虽然这些措施是有效的，但它们也有一些缺点。每一步都需要时间，如果蚀刻和底漆程序完全执行，它们会大大增加处理时间。此外，还有被唾液、血液或水污染蚀刻或底漆表面的风险。如果发生这种情况，必须清洁牙齿表面，并且必须重复蚀刻和底漆程序。为牙医简化粘接过程是可取的。新一代粘合剂系统采用了一种策略，使用低pH值树脂底漆同时脱矿和渗透矿化牙齿表面。本临床试验的目的是比较单组分自蚀刻粘接剂（p - sea）与常规粘接剂在非龋齿宫颈病变中的临床表现。

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.
