COMPARISON OF EFFECTIVENESS OF TOTAL ETCH VS SELF ETCH DUAL CURE RESIN CEMENT FOR LUTING OF GLASS FIBER POST - AN IN VITRO STUDY.

Introduction: The purpose of this study was to evaluate the influence of dual cure resins with total etch and self etch adhesive systems on the retention of fiber posts. Method: 60 freshly extracted human maxillary incisors with straight roots were biomechanically prepared. Obturation was done with gutta percha. The post space was created. The specimens were divided into two groups of 30 teeth each according to the material used for luting of posts. Group 1 had dual cure resin cement with total etch adhesive (Relyx ARC cement), group 2 had dual cure resin cement with self etch adhesive (Panavia). Prepared samples were tested on the Universal testing machine for pull out strength. Result: Among the cementing media the pull out strength obtained with group 1 (dual cure resin cement with total etch, Relyx ARC) and group 2 (dual cure resin cement with self etch, Panavia F) was the same. Conclusion: Based on the results of this study it can be concluded that the dual cure resin cement with total etch as well as self etch were equally efficacious in the retention of post.
