Fracture resistance of roots obturated with three different materials

Effect of double antibiotic and calcium hydroxide pastes on dislodgement resistance of an epoxy resin-based and two calcium silicate-based root canal sealers

“…Dislodgement resistance of root canal filling to radicular dentin prevents coronal and apical leakage and supports the dental tissue against root fracture [31,32] and resist dislocation of root filling during operative procedures, post space preparation, and tooth flexure [30,33]. Previous studies have shown that a material that has high push-out test results contributes to the longevity and prognosis of root canal-treated teeth [32,34] .…”

Resistance to fracture of roots filled with different sealers

“…Previous studies have shown the diffi culty of obtaining uniform fracture strengths for human teeth because of natural variations in tooth morphology 13,14) . Emulating the experimental protocols of Karapinar Kazandag et al 5) and Ulusoy et al 10) , optimum care was taken in this study to standardize the experimental teeth according to their tooth sizes and dimensions and working length measurements.…”

“…On the one hand, one study 9) found no signifi cant differences in fracture resistance between roots fi lled with a bondable root canal fi lling system, Epiphany, and those fi lled with gutta percha and an epoxy resin-based sealer, AH 26. On the other hand, a study 10) found that the fracture resistance of roots fi lled with gutta percha and AH 26 was superior to that of roots fi lled with the Epiphany system.…”

On the other hand, a study 10) found that the fracture resistance of roots fi lled with gutta percha and AH 26 was superior to that of roots fi lled with the Epiphany system.Recently, a new root canal sealer, iRoot SP (Innovative BioCreamix Inc, Vancouver, Canada), was introduced to the market. According to the manufacturer, iRoot SP is a convenient, pre-mixed, ready-to-use injectable white hydraulic cement paste developed for permanent root canal fi lling and sealing applications.…”

Resilon: A Comprehensive Literature Review

“…145-148 However, one study showed that forces to fracture were higher in root canals filled with AH-plus/gutta-percha. 149 In contrast to these two groups of studies, some investigations have concluded that there is no significant improvement in resistance to vertical root fractures with the use of Resilon compared with conventional gutta-percha and sealer. 150-158 One investigation demonstrated that fracture resistance of roots are significantly affected by the type of intra-orifice barrier, and the use of Vitremer and fiber-reinforced composite resin significantly improves fracture resistance; on the other hand, MTA has not exhibited any reinforcing effect as an intra-orifice barrier.…”
