Abstract


Statement of problem: There is still dilemma regarding the choice of material for fracture repair and the strength associated with it.

Purpose: Therefore the study aims to compare the transverse strength of self cure and visible light cure resin as repair material before and after surface treatment.

Material and method:

60 heat cure resin samples of dimension 65 x 10 x 2.5 mm were cut into 2 equal parts with 45 degree bevel and placed in mould with 3 mm gap in middle for adhering with repair material after surface treatment following which they were tested for transverse strength.

RESULT: The best bond strength was obtained with self cure resin after surface treatment.

CONCLUSION: Repair with self cure resin exhibited higher transverse strength than light cure resin especially after surface treatment.
