Abstract

The tolylene diisocyanate molecule was reacted first with 2-hydroxyethyl methacrylate and then with a phenol. The adduct molecule provides two bonding sites: one to the collagen of dentin, and the other to the filling resins. This bonding agent was developed and tested with three tensile strength tests. A method using a hemispherical cavity in dentin was further developed to study microleakage using a silver staining technique and quantified by image analysis and mathematical transformations to correlate bond strength to microleakage. The three methods used freshly extracted third molars in the form of a 400-μm micron slice, a hemispherical cavity in dentin and a flat dentin surface for the three methods, respectively. Mean values were 2192.25, 183.25, and 377.12 psi, respectively.
