Title: Effects of different porcelain bonding systems combined with ceramic surface treatments on the shear bond strength between porcelain and bovine enamel
Abstract: Objective:To study the appropriate combinations of porcelain bonding systems and ceramic surface rouging treatments on the bonding of porcelain to bovine enamel.Method: Seventy discs of Vita VMK95 porcelain were randomly divided into 2 main groups (n = 36). The ceramic specimens received 4 different surface roughing treatments. All discs were bonded to bovine enamel with 2 different porcelain bonding systems. All cemented specimens were tested with shear loading until fractured on a universal testing machine after immersed in 37 ℃water for 24 h. Data were analyzed with 3-way analysis of variance (P0.05).Result: Phosphoric acid-etching without sandblasting produced the lowest bond strength and there were no significance among the other three treatments. Panavia F groups had the highest mean shear bond strength(29.38 MP).Conclusion:The appropriate bond strengths were obtained by sandblasting followed by hydrofluoric acid-etching or hydrofluoric acid-etching in the two porcelain bnding system.
