“…The use of glass fiber posts has gained acceptance, particularly on premolars and anterior teeth. Their modulus of elasticity is similar to dentine, allowing better dissipation of masticatory loads through the tooth, which does not occur with cast metal posts [16]. The amount of remaining ferrule seems to be the predominant factor for tooth survival in extensively structurally compromised non-vital teeth [17].…”

Purpose: The purpose of this in vitro study was to compare the effect of endocrowns and glass fiber postretained crowns on the fracture resistance of endodontically treated maxillary premolars made of different ceramics materials. Materials and Methods:Thirty sound maxillary premolars were endodontically treated. They were randomly assigned into 3 groups (n=10), in which, teeth were prepared to receive all-ceramic restorations. GP: fiber post and resin core and ferrule with all-ceramic (IPS E-max CAD, Ivoclar-Vivadent) conventional crown. GE: Endocrown with butt joint finish line design made of (IPS E-max CAD, Ivoclar-Vivadent). GC: Endocrown with butt joint finish line design made of hybrid nanoceramic (CERASMART, GC Dental, USA). The lithium disilicate (IPS E-max press, Ivoclar-Vivadent) and hybrid nanoceramic (CERASMART, GC Dental, USA) all-ceramic restorations were made by CAD/CAM system (CEREC MC XL SW 4.0) and adhesively cemented with dual-cure resin cement (BisCem Bisco, Inc, USA). Specimens were mounted in a universal testing machine (Model 3345; Instron Industrial Products, Norwood, MA, USA). Each specimen was loaded to failure at a crosshead speed of 5.0 mm / min. Mode of failure was also examined. Data were analyzed using one way analysis of variance (ANOVA) and Tukey's post hoc significance difference tests. Differences were considered significant at P<0.05. Results:One way ANOVA test showed that group (GC) recorded statistically significant (p<0.05) highest mean value (1522.64 N) followed by group (GP) (1301.34 N) then group (GE) (725.73 N). Group (GE) recorded the lowest statistically significant (p<0.05) mean value (725.73±137.89 N). Pair-wise Tukey's post-hoc test showed nonsignificant (P>0.05) difference between GP and GC groups. Conclusions:Within the limitations of this study, all fracture resistance loads obtained in this study were far beyond the maximum masticatory forces and the presence of hybrid nanoceramic increased the fracture resistance of endodontically treated maxillary premolars restored with endocrown than those restored with lithium disilicate endocrowns, in failure mode hybrid nanoceramic showed favorable fracture pattern than lithium disilicate.

“…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.…”

“…129 Another limitation of this study is that the mode of failure obtained in the included in vitro studies was not compared to the mode of failure that occurs clinically. Many variables may influence the mode of failure of endodontically treated teeth restored with post and core, such as elasticity modulus 130 , diameter 41,42 and length of the post 71,82 , and ferrule effect. 27 These variables must be taken into account when comparing in vitro and clinical studies to avoid misleading conclusions.…”
