Abstract :

Background: There are several dentin surface drying techniques to provide a perfect resin penetration on dentin. There are two techniques which will be compared in this study. The first technique was by rubbing dentin surface gently using cotton pellet twice, this technique is called blot dry technique.  The second technique is by air blowing dentin surface for one second and continued by rubbing dentin surface gently using moist cotton.  Purpose:  This experiment was aimed to know the best dentin surface drying techniques after 37% phosphoric acid etching  to obtain the optimum tensile bond strength between hydroxyethyl methacrylate (HEMA) and dentin surface. Method:  Bovine teeth was prepared flat to obtain the dentin surface and than was etched using 37% phosphoric acid for 15 seconds. After etching the dentin was cleaned using 20 cc plain water and dried with blot dry techniques (group I), or dried with air blow  for one second (group II), or dried with air blow for one second, and continued with rubbing gently using moist cotton pellet (group III), and without any drying as control group (group IV). After these drying, the dentin surfaces were applied with resin dentin bonding agent and put into plunger facing the composite mould. The antagonist plunger was filled with composite resin. After 24 hours, therefore bond strength was measured using Autograph. Result: Data obtained was analyzed using One-Way ANOVA with 95% confidence level and continued with LSD test on p ≤ 0.05. The result showed that the highest tensile bond strength was on group I, while the lowest on group IV. Group II and IV, III and IV, II and III did not show signigicant  difference (p>0.05). Conclusion: Dentin surface drying techniques through gentle rubbing using cotton pellet twice   (blot dry technique)  gave the greatest tensile bond strength.
