Popis: | Aim: The aim of this study is to evaluate the effect of a self-etching primer (SEP Adper Prompt L-pop; 3M ESPE) on the shear bond strength of a conventional light cure composite resin (Transbond XT primer) in the dry state. Materials and Methods: Forty Freshly extracted human premolar teeth extracted for orthodontic purpose were collected and divided into two groups and mounted on colour coded acrylic blocks. Premolar brackets were bonded using a conventional light cure composite resin and primer in Group I and a self-etch primer was used in Group II. The shear bond strength was evaluated using Instron Universal Testing Machine with an occlusal shear force applied directly onto the enamel-bracket interface with a crosshead speed of 0.5 mm/min. Results: No statistically significant difference were observed in the bond strengths of the two groups evaluated. Conclusion: These results indicated the SEP evaluated showed satisfactory bond strength and is potentially adequate for orthodontic bonding needs. |
