“…Today, commonly used root canal sealers are based on polyketone, glass ionomer, zinc oxide-eugenol (ZnOE), epoxy resin, calcium hydroxide, methacrylate resins, mineral trioxide aggregate (MTA), or silicone 23) . Adhesion between dental structures and resin-based sealers is the result of a physicochemical interaction across the interface, developing a bond and allowing the union between fi lling material and root canal wall 24,25) .…”

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...

Evaluation of the responses of MHC class II molecule-expressing cells and macrophages to epoxy resin-based and 4-META-containing, methacrylate resin-based root canal sealers in rat subcutaneous tissue

Major histocompatibility complex (MHC) class II molecule-expressing cells and macrophages play a pivotal role in mediating the host tissue response to biomaterials. This study investigated the responses of these cells to epoxy resin-based and 4-META-containing, methacrylate resin-based endodontic sealers (AH Plus and MetaSEAL respectively) in rat connective tissue. Silicone tubes loaded with one of the sealers or solid silicone rods (control) were subcutaneously implanted in male Wistar rats for three time periods of 7, 14, or 28 days. Tissue specimens were immunoperoxidase-stained for MHC class II molecules and CD68 (a general macrophage marker). Results showed that AH Plus-implanted tissue displayed significantly more MHC class II-positive cells than the control at 14 and 28 days, whereas MetaSEAL-implanted tissue showed significantly more CD68-positive cells than both AH Plus-implanted tissue and the control at all time periods. It was concluded that the epoxy resin-based sealer induced the infiltration of MHC class II molecule-expressing cells, whereas 4-META-containing, methacrylate resin-based sealer elicited macrophage infiltration.
