“…Leur module d'élasticité est semblable à celui de la dentine. Leur profil de surface lisse en fait des tenons passifs qui n'exercent pas de stress sur la dentine radiculaire [10]. En plus de leur intérêt esthétique lors de la réalisation des couronnes céramo-céramiques, les reconstitutions corono-radiculaires à tenon fibré permettent une économie tissulaire, préservant ainsi la solidité de la dent dépulpée, contrairement aux reconstitutions corono-radiculaires coulées indirectes qui nécessitent une mise de dépouille interne de la dent [11].…”

“…As endodontically treated teeth are weaker and more prone to fracture than vital teeth, 2 the obturating material that strengthens the root is mandatory. 3 Therefore, the use of a root canal sealer possessing an additional quality of strengthening the root against fracture would be of obvious value. 4 Several root canal sealers like zinc oxide eugenol sealers, calcium hydroxide-containing sealers, glass ionomer-based sealers, resin-based sealers, and mineral trioxide aggregate (MTA)-based sealers have been used along with gutta-percha (GP) for the obturation of root canals.…”

Aim: To evaluate and compare the effect of epoxy resin-based sealer and a pozzolan-based mineral trioxide aggregate (MTA) sealer on the fracture resistance of endodontically treated teeth. Materials and methods:Thirty single-rooted mandibular premolars were decoronated to a standardized root length of 15 mm. ProTaper rotary files up to a master apical file size of F3 were used for cleaning and shaping the root canals followed by 2.5% sodium hypochlorite irrigation. The teeth were randomly divided into three groups (n = 10 each), and the obturation was completed using gutta-percha with Endoseal MTA (group I) and AH Plus (group II) as root canal sealers. Group III served as control (instrumented and unfilled). Each specimen was then subjected to fracture testing by using a universal testing machine at a crosshead speed of 1.0 mm/minute until fracture. The force required to fracture each specimen was recorded and the data were subjected to statistical analysis using one-way analysis of variance (ANOVA), followed by pairwise comparison using post hoc Games-Howell test (p < 0.05). Results:The fracture resistance of groups I and II were significantly higher than those of group III. No significant difference in the fracture resistance was observed between group I (Endoseal MTA) and group II (AH Plus) groups. Conclusion:It can be concluded that the new root canal sealer, Endoseal MTA, is able to reinforce the tooth against fracture as good as AH Plus.Clinical significance: Endoseal MTA is a sealer for the reinforcement of endodontically treated teeth.

“…The reason often cited is removal of tooth structure during endodontic treatment and dehydration of dentin. The major goal of endodontic therapy should be reinforcement of the residual tooth structure [2]. Since the retention of an adhesive restoration is based on micromechanical retention and does not require macro-retentive elements, minimal invasive preparation with maximal conservation of dentinal tissue can be realized.…”
