A Comparative Shear Bond Strength Analysis of Recent Generation Bonding System to Cervical Dentin

Bhat Ganesh T, Hegde Priyadarshni, Hegde Mithra N

Abstract :

Twenty five non carious intact human molars and fifteen carious human molars with cervical sclerotic lesions were selected for this study. The specimen were divided into two groups: the control group contained 10 non carious intact human molars. The cervical surfaces of the specimen were treated to receive dentinbonding agent as per the manufacturer instructions. All the forty samples were tested for bond strength in Hounsfield Tensometer.

The experimental group was divided into 3 groups

Group 1: Prompt L Pop(self etching primer)

Group2: clearfil liner bond 2V(self etch primer)

Group 3: excite (single bottle bonding agent) Results: Clearfill liner bond 2V required the highest mean shear load to fracture in both sclerotic dentin (12.18 MPA) and normal dentin (8.94MPA). Prompt L Pop required the lowest mean shear load in both sclerotic dentin (8.17MPA) and normal dentin (6.28MPA).Inter comparison was done using Kruskal Wallis test where sclerotic dentin and normal dentin were compared with each other. The results showed very highly significant difference.
