EFFECT OF DIFFERENT SALIVA DECONTAMINATION PROCEDURES ON THE SHEAR BOND STRENGTH OF A UNIVERSAL EIGHTH GENERATION ADHESIVE SYSTEM TO DENTIN AFTER POLYMERIZATION - AN IN VITRO STUDY

Aim: To evaluate and compare the effect of saliva decontamination procedure on shear bond strength a Universal eighth generation adhesive system to dentin after polymerization. Materials & Method: Forty extracted non-carious premolars were mounted acrylic block their occlusal surfaces grounded flat exposed middle depth dentin. The teeth then randomly divided into five Groups: Group A(control), B(Bonding, Saliva, Air-dried), C(Bonding, Air-dried, Rinse), D(Bonding, Re-bonding) E (Bonding, Rinse, Re-bonding). A teflon tube 2x3 mm dimension was used pack composite treated surface light cured for 40s. Shear Bond measured using instron testing machine at crosshead speed 1mm/min. Data statistically analysed ONE WAY-ANOVA TUKEYS test. Result: It observed that, highest mean found in E(Bonding, with value 23.87 each. least seen 13.25. When an intergroup comparision made, significant difference between various groups except A(control)-Group Re-bonding)-Group Air-dried)-Group Rinse). Conclusion: Salivary contamination significantly decreases Rinsing Air-drying contaminated not sufficient restore strength. However reapplication rinsing air-drying fully restored
