Del-Nero Beneitez, María Olga and Macorra García, José Carlos de la (1999) Sealing and Dentin Bond Strengths of Adhesive Systems. Operative dentistry, 24 (4). pp. 194-202. ISSN 0361-7734
The objectives of this research were (1) to analyze the variations of the permeability of dentin after restoration with two polyacid-modified resin composites (Compoglass, Dyract) and four single-bottle adhesives (Prime & BOnd 2.0, Syntac Single Component, OptiBond Solo, and Single Bond -Scotch Bond 1 in Europe- immediately (approximately 1 hour) after insertion. A perfusion system with distilled water was used at a pressure of 32.5 cm of water; (2) to study the bond strength of their interfaces; and (3) to find the correlation, if any, between both parameters. None of the materials used produces a complete cessation in fluid filtration. Tensile strengths were very low (maximum: P&B=3.96MPa) probably because of the very large bonding surfaces used (mean bonded surface area = 88.8mm²). No significant correlation was found between tensile bond strength and the sealing ability for any material.
