Abstract

Introduction: CEMENTing plays an important role in increasing the RETENTION, stress distribution and seal of micro gap and porosity between post and tooth. The purpose of this study was determination and comparison of the mean retentive strength of cast posts with zinc phosphate, poly carboxylate, glass ionomer and resin CEMENTs.Methods and materials: Forty recently extracted human teeth were endodontically treated. Fore groups of 10 specimens formed. Post pattern made with acrylic resin and casting was fabricated using base metal alloy. Each group was CEMENTed with 1 of 4 CEMENTs: Zinc phosphate, ploy carboxylate, glass ionomer and resin CEMENT. Then, specimens mounted in acryl and tensile bond strength of them measured with a universal testing machine. The data analyzed by one-way ANOVA and Turkey test.Results: A significant difference between mean retentive strength of the CEMENTed cast posts with these CEMENTs was shown (p value =0.06); after final assessment of Turkey test, it was appeared that the RETENTION of posts CEMENTed with poly carboxylate was significantly better than posts CEMENTed with Zinc phosphate (p value =0.010). In addition, RETENTION of posts CEMENTed with poly carboxylate was significantly better than posts CEMENTed resin CEMENT (p value =0.012).Discussion: Despite the limitations of this study, the use of poly carboxylate CEMENT provided greater retentive strength than the Zinc phosphate for cast metal posts. Between poly carboxylate, resin, and glass ionomer; however, there was no significant difference in terms of RETENTION.
