Abstract

Background and Aim: Post RETENTION has a considerable effect on restorative treatments and is influenced by various factors. The purpose of this study was to evaluate the effect of dentinal SMEAR LAYER on the RETENTION of CUSTOM-made posts luted with composite resin and ZINC PHOSPHATE CEMENTs.Materials and Methods: Forty single-rooted lower premolars were decoronated, filed and filled with gutta-percha and divided into 4 equal groups. Post spaces were prepared to a length of 8 mm. direct post patterns were made with acrylic resin and castings were fabricated using Ni-cr alloy. In Groups A and C, the post spaces were rinsed with 2 ml of 0.9% normal saline. The specimens in Groups B and D were rinsed with 1 ml of 17% EDTA followed by 1 ml of 5.25% Naocl and 10 ml distilled water. After drying, ZPC (Dentsply) was used for cementation in groups A and B. The samples in Groups C and D were luted with Panavia F2.0. RETENTION was measured on a Universal Testing Machine at 0.5 m/min. Data were subjected to statistical analysis using ANOVA. Results: The mean amount of RETENTION was 19.66±1.98 kg, 19.72±2.08 kg, 20.99±2.08 kg and 22.17±3.66 kg in groups A, B, C and D, respectively. There was no significant difference between the groups, but the mean value was highest in group D.Conclusion: The use of RESIN CEMENT provided greater RETENTION for CUSTOM-made posts compared to ZPC. Removing dentinal SMEAR LAYER did not significantly affect the RETENTION of CUSTOM-made posts cemented with ZPC or Panavia F2.0.
