Although the majority of the studies reported that the use of root canal sealers increased the fracture resistance of endodontically treated teeth , conflicting evidence was found for the reinforcing effect of resin , glass ionomer , and calcium silicate-based sealers while there was moderate evidence for zinc oxide eugenol-based sealers in favor of no reinforcing effect .
Conclusion On the basis of available evidence , the use of root canal sealer increases the fracture resistance of endodontically treated teeth .
Regarding the comparisons among the sealers , no conclusions could be drawn for the superiority of one sealer type to another .
Objective The purpose of this study was to systematic ally review and critically analyze the published data of in vitro studies testing the effect of root canal sealers on the fracture resistance of endodontically treated teeth .
The properties of Endocal 10 and its potential impact on the structural integrity of the root.
The purpose of this research was to determine if the use of Endocal 10 ( previously called Biocalex 6.9 ) is associated with root fracture and to assess its sealability . Thirty-six freshly extracted , single canal human m and ibular incisors were instrumented and r and omly divided into two equal groups ( n = 15 ) . Canals in group A were obturated with vertically compacted gutta-percha and Sealapex , and those in group B were filled with Endocal 10 placed with a # 25 Lentulo spiral per manufacturer 's instructions . Two blinded investigators evaluated the teeth for fractures using transillumination and an operating microscope at 12 x magnification . Three of the fifteen sample s filled with Endocal 10 had vertically fractured in half , whereas none of the teeth filled with gutta-percha had any evident fracture lines . The remaining teeth were tested for leakage via a fluid filtration model at 1 wk and 30 days postobturation . No leakage was found among any of the sample s whether filled with gutta-percha or with Endocal 10 at either time interval . Statistical analyses were completed using Fisher 's exact test ( p = 0.023 ) , which showed that there was a significant increase in chance of fracture when using Endocal 10 versus gutta-percha . The results indicate that , although Endocal 10 is able to seal the tooth as well as gutta-percha and sealer , there is a significant potential risk of root fracture
