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.
