COMPARATIVE EVALUATION OF BOND STRENGTH OF TWO DIFFERENT REPAIR RESIN MATERIALS: AN- IN VITRO STUDY
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.
