Influence of resin-based adhesive root canal fillings on the resistance to fracture of endodontically treated roots: an in vitro preliminary study

Influence of different endodontic filling materials on root fracture susceptibility

“…[1][2][3][4] This type of fracture has an unfavorable prognosis and often leads to tooth extraction. 5,6 Root fractures can be derived from dental tissue removal during canal instrumentation 7,8 , preparation of intraradicular post space 2 , intracanal medication for more than 30 days 9 and excessive pressure during root obturation. 3,6 However, conclusive epidemiological evidence of weakening in the root-filled teeth is still lacking.…”

“…The sealer matrix consists of bisphenol-A-glycidyldimethacrylate (BisGMA), ethoxylated BisGMA, urethane dilethacrylate and hydrophilic methacrilate with calcium hydroxide, barium sulfate, barium glass, bismuth oxychloride and silica. 8,16,17 This system uses a self-etching primer and also comprises Resilon (Resilon Research LLC, Madison, CT, USA), which is a thermoplastic synthetic material that contains bioactive glass, bismuth oxychloride and barium sulfate. 8,17,18 Some authors reported that the Epiphany/Resilon system creates a monoblock that tightly adheres to dentine.…”

“…19 Vertikal kök kırığı en çok endodontik tedavi görmüş dişlerde gözlendiği ortaya konmuştur. 20 Dişle-rin kırma direnci inceleyen çalışmalar genelde kanalın konisitesini 21 , post yerleştirilmesinin etkisini 22 , kanal dolgu patlarının veya doldurma yöntemlerinin etkisini 23 , kanal doldururken kullanılan spreader"ın numarasını 24 , farklı restorasyon maddelerinin etkisini 25 ve kalsiyum hidroksit kullanılmasının etkisini incelemiştir 26 , literatürde sadece kanal genişletme prosedürlerinin dişlerin kırılma direncine etkisini inceleyen çok az çalışma mevcuttur. 27 Biz ise çalışmamızda sadece farklı kanal geniş-letme prosedürlerinin etkisini incelemek istedik.…”

Influence of Five Different Root Canal Sealers on Root Fracture Susceptibility

“…It is thought that adhesion and mechanical interlocking between the root canal filling material and radicular dentin reduce the risk of fracture and strengthen the remaining tooth structure. 6 The purpose of this study was to compare the fracture resistance of roots filled with gutta-percha (GP) and sealed with one of the following five root canal sealers: epoxy resin-based AH Plus, resin-based EndoRez, resinbased RealSeal, MTA-based MTA Fillapex, and calcium hydroxide-based AcroSeal. The null hypothesis was that the type of root canal sealer would not influence the fracture resistance of root-filled teeth.…”
