Abstract:

OBJECTIVE: To explore the difference of various adhesives and dentin bonding strength, in order to provide a reference for the clinical practice.
METHODS: A computer search was performed in VIP database for articles related to adhesives and dentin bond strength, retrieval time was between January 1998 and October 2009. Chinese keywords: adhesives; dentin; bond strength. After the first trial, the citations of each article were checked, a total of 22 literatures were selected.
RESULTS: The dentin adhesive is used for dentin surface, it can enhance the retention of dental prosthetic restoration, and improve the closure of dentin wall. Cement-like material and resin material are commonly used in clinical materials for dental restoration. In recent years, they have achieved great development. Resin-based adhesives are superior to cement-like adhesives due to the advantages of high compressive strength, small solubility, low micro-leakage rate, small viscosity at harmonic state, high degree of body moisture, and good chemical bonding with the tooth structure. Resin-based adhesives show superior performance of bonding adhesion. Resin adhesives have been developed to 6-7 generations, characterized by single-bottle package, self-etching, without mixing, bonding strength maintained at 18-25 MPa. This type of resin adhesives can significantly improve the work efficiency of physicians and reduce the possibility of human error.
CONCLUSION: There is no kind of adhesives or bonding method suitable for all dental restorations. An optimal bonding program should depend on the individual conditions of patients, medical conditions and physician controlled theoretical and practical knowledge. Moreover, with the rapid update of repair materials and increasing requirement to improve repair quality, bonding technology will continue to develop.
