Comparative Evaluation of Novel 'S' Shape Post with Omega and Modified Omega Shape Post in Primary Anterior Teeth: An in Vitro Study

Dr. Savitha Satyaprasad, Dr Rashmi S

Abstract: Background: Success of rehabilitation of Early childhood caries (ECC) following endodontic therapy with post and core depends on various factors and one such significant factor includes post design. Many conventional post shapes owing to their small surface area and inadequate adaptability to the canal provided unsatisfactory results. Thus, in this study, a novel 'S' shape post is designed and compared for retention, fracture resistance and failure type with omega and modified omega shape post in primary anterior teeth. Method: Thirty three extracted maxillary anterior primary teeth were cut up to 1 mm above the CEJ and pulpectomy was performed with ZOE and 1mm layer of GIC leaving 3 mm space below CEJ for post placement. Teeth were randomly divided into 3 groups: Group I:S shape post, Group II: omega shape post & Group III: modified omega shape post. Core buildup and strip crowns were placed using composite material. Teeth were tested under Universal Testing Machine (UTM) & type of fracture were observed under digital microscope (DM). Results: Group II showed highest mean fracture resistance (251.3 ± 48.50) followed by group II (180.9 ± 15.81) and group III (81.15 ± 10.33) respectively. Type I favorable fracture was observed in group III (100%) and Group I (81.81%) and type II unfavourable fracture seen in group II (100%) and group I (18.18%). Conclusion: 'S' shape post and omega shape post serves better retention & resistance than modified omega shape post. This novel 'S' shape post can be used as an alternative to conventional shapes for better retention along with less chances of unfavorable fractures that can be retreated.
