Fracture resistance of simulated incomplete vertical fractured teeth treated with different bioceramic based root canal sealers

AUTHOR(S): Levent Demiriz and Ebru Hazar Bodrumlu
ABSTRACT:Introduction: The aim of this study was to examine fracture resistance after filling simulated incomplete vertical fractured permanent teeth using two different bioceramic based sealers.
Material and Methods: Sixty single-rooted maxillary incisors were decoronated to a length of 13 mm. The teeth were randomly divided into four groups (n=15 for each group). In negative control group, the teeth were left with no process. For positive control and two experimental groups, 45 roots were prepared by using Protaper System up to a master apical file size of F3. In these 45 roots, a simulated fracture line (6.5 mm length, 0.25 mm width) extended until the root canal space was created from the root apex towards crown. In positive control group, 15 teeth were filled with only gutta-percha. In experimental groups, first group filled with gutta-percha + Well Root ST sealer, and the other group filled with gutta-percha + MTA Fillapex sealer. Each sample was tested for the fracture in universal testing machine at a crosshead speed of 1.0 mm/min-1. The fracture resistance of each sample was recorded, and the obtained data was analyzed statistically.
Results: The highest fracture resistance value was observed for the negative control group (P<0.05). Well Root ST showed significantly higher fracture resistance in comparison to the MTA Fillapex (P<0.05). The fracture resistance was significantly higher for both sealer groups than it was for the positive control group (P<0.05).
Conclusion: Well Root ST and MTA Fillapex sealer significantly increased the fracture resistance of untreated incomplete vertical fractured roots.
