Effect of Different Luting Agents on the Retention of Cast Metal Complete Crowns Prepared with Different Surface Textures: An in Vitro Study

Manju Choudhary

Abstract: Objective: To evaluate the influence of tooth surface textures prepared with diamond rotary instruments on the retention of cast metal complete crowns cemented with five different luting agents. Method: One hundred and fifty intact human molar teeth were prepared into three equal groups of different surface textures such as, Coarse, Regular, and Fine using diamond rotary cutting instruments of respective grit sizes. Teeth preparation with standard finish line and axial inclination were performed using Milling machine. Axial surface areas of prepared tooth specimens were measured using software called AutoCAD. Cast crowns of each group were cemented with five luting agents namely: zinc phosphate (Harvard), zinc polycarboxylate (Poly-F), glass ionomer (GC Fuji-I), resin modified glass ionomer (3M Vitremer,) and adhesive resin cement (3M- Rely-X ARC). The testing of the specimens to determine the tensile bond stress of cemented crowns was performed with a Hounsfield Tensometer unit. Results: Statistical analysis of tensile stress indicated a very highly significant (p
