Abstract :

Background: Adhesives are integral to modern restorative dentistry for enhanced functional and esthetic outcomes. The use of lasers for improved bonding is on the rise and there is a need to understand the effect of lasers on adhesives. Aim: The study aims to evaluate the effect of diode laser irradiation on one-step self-etch adhesive before their polymerization on the shear bond strength between resin cement and dentin. Materials and Methods: Thirty extracted human teeth were collected and the buccal surface was grounded till dentin was exposed. A window of 3mm x 3mm was made on all the specimens that served as test sites and were randomly allocated to three groups (n = 10); Group 1: G-Premio bond without laser irradiation followed by photopolymerization; Group 2: G-Premio bond with laser irradiation without photopolymerization, and Group 3: G-Premio bond with laser irradiation followed by photopolymerization. The Shear Bond Strength (SBS) was determined using a Universal Testing Machine. One-way ANOVA followed by post hoc Tukey test was used with a level of significance at P ? 0.05. Results: SBS was significantly highest among Group 3 followed by Group 1 and the least SBS was found in Group 2 (P < 0> Conclusion: G-Premio bond irradiated with a diode laser followed by photo-polymerization exhibited the highest SBS.
