Background: Over the last decade, adhesive dentistry has been expanding at a rapid rate. Universal bonding agent and eighth-generation bonding agent are widespread in dentistry today. Saliva is the main contaminant in oral cavity which hinder the bonding. Aim: To evaluate the influence of saliva decontamination technique on the shear bond strength of fiber reinforced core build up material to dentin using ‘universal’ adhesive and ‘eighth-generation’ adhesive. Materials and Methods: Total sixty freshly extracted premolars were randomly distributed into two separate groups of adhesives. Group A- 3M Scotchbond Universal adhesive (3M ESPE, St Paul, MN, USA) and Group B - Futurabond DC (Voco, Germany). Samples were again subdivided into three subgroups (n=10): subgroup-1 Control (without contamination), subgroup-2 Contamination, subgroup-3 Decontamination. Samples were restored with short fiber reinforced composite restoration. Universal Testing machine was used to evaluate the Shear Bond Strength (SBS). Statistical analysis: The obtained data were examined statistically using one-way ANOVA, followed by Tukey’s post-hoc test HSD test (p<0.05)Results: Group B shown statistically higher mean shear bond strength compared to Group A (p<0.05). In both adhesive groups, maximum mean shear bond strength was obtained in subgroup-1 whereas the lowermost mean shear bond strength was seen in subgroup-2. Conclusion: Salivary contamination significantly affects the shear bond strength (SBS) of short fiber reinforced composite to dentin using universal adhesive and eighth generation self-etch adhesive. Bond strength significantly improved after reapplication of bonding agent.
