After endodontic treatment, teeth are structurally different from untreated vital teeth, so these teeth require specialized treatment. The toughness of an endodontically treated tooth is associated to the tooth structure left. In vertical root fracture, resection of the affected root or extraction of the tooth is mandatory. Hence, this is a serious concern as there is an unfavorable prognosis leading to endodontic failure. One major cause for tooth fracture is found to be endodontic treatment in many in vivo studies. Vital teeth are less prone to fracture than nonvital teeth. It is a well-known fact that loss of structural integrity associated with the access preparation results in increased cuspal deflection during function leading to a higher occurrence of fractures. It is difficult to establish whether the occurrence of fractures depends on change in dentin structure or missing tooth structure. If endodontically treated teeth are not restored immediately, there is bacterial contamination and coronal microleakage, and this can lead to retreatment or endodontic failure. Hence, bonded restorations must be used to avoid microleakage. Based on above findings the present study was planned to evaluate the In Vitro Evaluation of Fracture Resistance of Endodontically Treated Teeth with the Use of Different Root Canal Sealers. The present study was planned in Department of Conservative Dentistry and Endodontics, Buddha Institute of Dental Science and Hospital, Patna, Bihar, India. For the in vitro study, 30 extracted maxillary central incisors from patients in the age group 30-55 years were obtained. After extraction, soft tissue and calculus were mechanically removed and teeth were stored in 5% sodium hypochlorite solution for 24 h to remove any remaining soft tissue. Certain teeth that had fracture lines, calcifications, surface irregularities were discarded, and a total of 20 teeth samples were obtained for the study. Although the sample size was small, it was sufficient to achieve a statistical difference. The teeth were sectioned at the cementoenamel junction using a diamond disc and water spray The sectioned teeth were taken, and a working length for each root was then established 1 mm short of the apical foramen using a No. 20 K-file. Further, the roots were divided randomly into four groups. The data generated from present study concludes that increased the fracture toughness of the instrumented roots after obturation. Therefore the ability of these materials i.e., Resilon and Epiphany sealer, Gutta-percha and AH plus sealer, guttapercha and Endomethasone sealer to reinforce the Endodontically treated teeth looks very promising but further long-term clinical studies are necessary to collect evidence based data thus to be able to support the confident use of these materials in day to day practice. Keywords: Fracture resistance, root canal sealers, Resilon, Epiphany, AH Plus Sealer, Endomethasone sealer, etc.

The Mean

Aim: To compare the retention and fracture resistance of three different pre-fabricated posts systems in endodontically treated anterior tooth. Materials and Methods: Root canal treatment was performed for all the 90 samples used in the study. After the completion of obturation, post space preparation was done accompanied by post cementation. The samples were divided into three groups depending on the post cemented (Stainless Steel, Glass fiber and Ceramic post). The samples were first evaluated for retention with a help of a three-jaw chuck, which grasped the post and tried to pull it out. The force required to dislodge each post was recorded in Newtons. To evaluate the fracture resistance, the samples were subjected to compressive loads at an angle. The load required was then recorded in Newtons. Results: The mean retention values for Stainless Steel post were significantly greater than those for Glass fiber post and Ceramic post. The mean retention values of glass-fiber post and ceramic post were not statistically different. The fracture load of the post system, it was revealed that highest mean value was seen in Stainless Steel post and was significant than ceramic post and glass-fiber post. Conclusion: Within the limitation of this study, it can be concluded that the pre-fabricated stainless steel post exhibits a significantly higher fracture resistance and also the retention was more as compared to Glass fiber post and Ceramic post.

Core Materials

Various material properties are involved in the success of endodontically treated restorations. At present, restorative composites are commonly employed as core build-up materials. This study aimed to systematically review the literature to assess the effect of using composite core materials on the in vitro fracture of endodontically treated teeth. Two different reviewers screened the literature, up to June 2021, in five distinct electronic databases: PubMed (MedLine), Scopus, Scielo, ISI Web of Science, and EMBASE. Only in vitro studies reporting the effect of the use of composite core materials on the fracture resistance of endodontically treated teeth were included. A meta-analysis was carried out using a software program (Review Manager v5.4.1; The Cochrane Collaboration, Copenhagen, Denmark). The risk of bias in each study was assessed following the parameters of another systematic review. A total of 5016 relevant papers were retrieved from all databases. After assessing the title and abstract, five publications remained for qualitative analysis. From these, only three studies remained for meta-analysis. The fracture strength of endodontically treated teeth where a core build-up composite was used was statistically significantly higher than the control (p = 0.04). Most of the analyses showed a high heterogenicity. The in vitro evidence suggests that the composite core build-up with higher filler content tended to improve the fracture resistance of the endodontically treated teeth, in comparison with conventional composite resins. This research received no external funding. Considering that this systematic review was only carried out on in vitro papers, registration was not performed. Furthermore, there were no identified clinical studies assessing core build-up materials; therefore, more well-designed research on these materials is needed.
