“…The results of this study agreed with those of Karapinar Kazandag et al 5) and and Cobankara et al 30) in that all the experimental groups showed signifi cantly superior fracture resistance than the negative control group. On the other hand, our results contradicted with those of Grande et al 36) and Kim et al 37) , in that they found no clear benefi ts with the use of root canal sealers in improving the fracture resistance of root canal dentin.…”

INTRODUCTIONRoot-fi lled teeth are more susceptible to fracture than vital teeth. Ironically, these teeth which were already compromised before root canal treatment are further weakened by the process. A few reasons contribute to the vulnerability of root-fi lled teeth, chief of which is root dentin dehydration after the endodontic procedures 1) . Other reasons that predispose root-fi lled teeth to fracture include brittleness of root-fi lled teeth because of loss of tooth structure 2,3) , excessive pressure during fi lling procedures 1,4) , and excessive widening of root canals 5) . After root canal treatment, the standard fi lling material is gutta percha. To obtain a hermetic seal, gutta percha is typically used in conjunction with root canal sealers because gutta percha is incapable of bonding to root canal walls. Root canal sealers not only fi ll the voids between gutta percha points, they also fi ll the voids between gutta percha and root canal walls 6) . Bondable root canal sealers purportedly improve the seal and fracture resistance of endodontically treated roots 7,8) . To date, confl icting results were reported from different research studies. 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.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. Based on a calcium silicate composition, iRoot SP is an insoluble, radiopaque, and aluminum-free material which requires the presence of water to set and harden.Another recently introduced root canal sealer is MTA Fillapex (Angelus Solucxoes Odontologicas, Londrina, Brazil). Based on an MTA (mineral trioxide aggregate) composition, other ingredients of MTA Fillapex include resins and silica (Table 1). According to the manufacturer, it has high radiopacity, low solubility in contact with tissue fl uids, low expansion during setting, and excellent viscosity for insertion. It does not stain the tooth and promotes deposition of hard tissue at the root apex and perforation sites.The purpose of the study was to compare the fracture resistance of roots fi lled with gutta percha and sealed with one of these three root canal sealers: an epoxy-based root canal sealer AH Plus (Dentsply DeTrey, Konstanz, Germany), a calcium silicate-based root canal sealer iRoot SP, and an MTA-based root canal sealer MTA Fillapex. The null hypothesis was that root canal sealers would not infl uence the fracture resistance of root-fi lled teeth. MATERIALS AND METHODS Root canal p...

“…Materials utilizing dentin adhesive technology have been adapted to obturating materials (3). RealSeal SE (RSSE) sealer (SybronEndo, Amersfoort, The Netherlands) was introduced for use with Resilon (Resilon Research LLC, Madison, CT, USA), which together form a monoblock inside the canal (2,4,5). This process is compromised if the resin cement used does not reach an adequate degree of conversion (DC) (6).…”

This study tested the null hypothesis that the opacity of RealSeal SE (RSSE) sealer makes light-curing inefficient, while the degree of conversion (DC) is similar regardless of curing method. Fourteen uniradicular teeth were sectioned at 15 mm from the apex. Root canals were instrumented using the Reciproc file system, bulk-filled with RSSE, and divided randomly into two groups (dual-cure or self-cure). DC was determined by micro-Raman spectroscopy at 24 h, 48 h, and 1 week after filling, at 6, 9, and 12 mm from the coronal end. Contrast ratio (Yb/ Yw) was used to determine the opacity of the material. Descriptive statistics and nonparametric tests were used, and significance was defined as a P value of less than 0.05. Opacity was almost total by the first section, at 6 mm. In dual-cure mode, DC values at 24 h were lower in the apical section (63.8%) than in the more coronal sections and were lower than in selfcured specimens (87.4%). Light-curing of the coronal end did not improve DC. These differences remained at 48 h and 1 week. Only a small (2%) but significant increase in DC was observed in evaluations at 24 h and 1 week.
