Abstract: Context: Adequate bonding of acrylic resin or composite teeth to denture base resin is necessary because it increases stiffness and strength, since the teeth become an integral part of the prosthesis. The strength of bond achieved at the interface of acrylic teeth and denture base may be significantly improved by various methods. Aim: To compare and evaluate effect of different surface treatments on the bond strength of acrylic and composite teeth with denture base materials. Settings and Design: An in - vitro study. Methods and material: Study samples were specimens of cross - linkedacrylic Central Incisors, which were divided into 2 main groups (A and B) groups and 4 sub - groups (I - IV). In order to simulate a clinical situation, a shear load was applied at cingulum of central incisor at 135? to its long axis using Universal Testing Machine at a cross head speed of 5 mm/min, until failure occurred. This angle was chosen to simulate the average angle of contact between maxillary and mandibular anterior in class I occlusion. Statistical analysis used: Data was tabulated and statistically analyzed, using one - way ANOVA multiple range test. A p value of <0.05 was considered as statistically significant. Results: The results of the current study clearly indicated that the incorporation of mechanical and chemical surface treatments significantly influence the bonding between denture teeth and denture base resin. Conclusion: The study results conclude that in order to minimize the incidence of debonding, the ridge lap glaze removal of acrylic teeth by combination of sandblasting followed by acid etching would probably be the most optimal combination.
