BONDING TO THE DENTAL SUBSTRATES AND THE MAIN TOPICS: A LITERATURE REVIEW

Abstract

Although the great improvement of the adhesive materials in the last years, the adhesion to the dental tissues still remains a point to be studied. The adhesion to the enamel has been considered as long term resistant, due to the fact that the enamel is a highly mineralized and physiologically homogeneous tissue. On the other hand, the adhesion to the dentin remains a challenge and continues being strongly studied, once this tissue present huge regional variance and humidity, what makes harder the obtainance of a consistent adhesion. Another relationship to be determined is the one between the bond strength and the marginal sealing, yet no well defined in the literature. So, the aim of the present study was to analyze and discuss some aspects that generate doubt when the adhesive process to the tooth structures is studied.
