“…According to previous studies, FEA models correlated very well with the observed fracture pattern in fracture strength tests, demonstrating reliable predictability for VRF [2324]. In the present study, a mandibular premolar tooth model was used, as mandibular premolars have been reported to be susceptible to fracture [25] and have been commonly used for fracture strength analysis in previous studies [78].…”

“…The diameter of the plunger is another parameter with inconsistent results in in vitro fracture strength studies [78]. In the present FEA results, the maximum stress concentrations exhibited changes at the contact area of the crown, but did not change within the root, when different plungers were used.…”

“…To date, many studies have evaluated the effects of various treatment protocols and applications, including root canal obturation with different filling materials and the application of different post-endodontic restorations, on the fracture strength of endodontically treated teeth [78]. However, divergent conclusions have been reported regarding the effect of such procedures on the fracture strength of endodontically treated teeth, potentially due to methodological differences among the studies.…”

Objectives The aim of this study was to investigate whether the diameter and direction of the plunger and simulation of the periodontal ligament (PDL) affected the stress distribution in endodontically treated premolars. Methods A fracture strength test was simulated via finite element analysis. A base model was set up, and the following parameters were modified: plunger diameter (3 mm vs. 6 mm), plunger direction (vertical vs. 135° angular to the central fossa), and PDL simulation. The analysis was conducted using the CosmosWorks structural analysis program, and the results are presented in terms of von Mises stresses. Results The smaller plunger increased the stresses at the contact area of the crown, but the plunger diameter had no effect on the stress distribution within the root. An angular plunger direction increased stresses within the root, as well as at the buccal cusp of the crown, compared with the vertical direction. Simulation of the PDL caused higher stress accumulation, especially in the cervical region of the root. Conclusions The plunger diameter had no effect on the stress distribution in the roots, whereas the plunger direction and PDL simulation did affect the stress distribution. More stringent standards can be established by taking such parameters into account when performing fracture testing in future studies.

“…* One-way analysis of variance power calculation for more than two groups was used to detect the proper sample size. Means and standard deviations were determined according to Guneser et al 2016 (29) based on the fracture resistance of obturated roots. The results showed that, at a power of 90% and a two-sided significance level of 5%; a total sample size of 40 single rooted teeth (equally allocated to five groups) will be adequate to reject the null hypothesis that the group means are equal; i.e.…”

Aim of the study: was to compare the in vitro effect of three different root canal sealers used with gutta-percha, on the fracture resistance of endodontically treated teeth. Materials and Methods: Forty extracted human single-rooted mandibular premolars were used for the study. Teeth were decoronated to a standard root length of 14 mm. MPro rotary files up to master rotary size 25/6% were used for preparing the root canals. Teeth were randomly divided into five groups (n = 8 each) based on the type of root canal sealers used and the obturation was completed using gutta-percha; Group I: AH Plus root canal sealer, Group II: Endoseal MTA sealer, Group III: Bioroot RCS sealer, Group IV: Control-1 (prepared-unfilled) and Group V: Control-2 (unprepared-unfilled). Each specimen was embedded in acrylic mold and subjected to fracture resistance test using a universal testing machine under compressive loading at a rate of 1.0 mm/min until fracture. The force required to fracture each specimen was recorded and the data obtained were statistically analyzed (analysis of variance (ANOVA) and paired-t test) with level of significance set at p ≤ 0.05. Results: The unprepared-unfilled group showed the highest mean fracture resistance followed by AH Plus group, Bioroot RCS group, then the Endoseal MTA group. While the prepared-unfilled group showed the least mean fracture resistance. There was no statistically significant difference between all groups. Conclusion: It could be concluded that Bioroot RCS and Endoseal MTA are able to reinforce the tooth against fracture as good as AH Plus.

“…There are several studies evaluating the effects of TSBSs on the fracture resistance of endodontically treated teeth (5,6,7); so, the aim of this study was to compare the effect of di-/tri-calcium silicate-based root canal sealers on the resistance of endodontically treated roots to vertical root fracture over different time intervals. Epoxy resin sealer (AH 26 Dentsply de Trey, Konstanz, Germany) was employed as reference material for comparison.…”

Purpose: The reinforcement effect of 3 various root canal sealers (AH 26, MTA Plus sealer and BioRoot RCS) and gutta-percha at different time periods (1 week and 1 month) were evaluated in the present study. Materials and methods: Single-rooted, single-canalled, cracks-free 80 mandibular premolars were decoronated to a length of 13mm. Group PC (positive control, n=10): samples were left unprepared and unfilled. Seventy samples were prepared by using the ProTaper Rotary System up to F4. Group NC (negative control, n=10): samples were left unfilled. Remaining 60 samples were assigned into 3 groups; Group 1: AH 26 + F4 gutta-percha (GP); Group 2: MTA Plus sealer + F4 GP and Group 3: BioRoot RCS + F4 GP. Filled samples were divided into subgroups according to storage time: Samples in Groups 1A, 2A, and 3A were stored for 1 week; while Groups 1B, 2B and 3B were stored for 1 month at 100% humidity to allow the complete setting of the sealers (n=10, for each). A universal testing machine at a crosshead speed of 1.0 mm/min was used for fracture testing. For each specimen, the force at the time of fracture was recorded and the data were analyzed statistically. Results: The highest fracture resistance values were obtained in Group PC, while the lowest values were obtained in Group NC. Groups PC and NC were statistically different from each other and from other groups, regardless of time (p<0.05). Fracture resistance values of Group AH 26/GP were statistically different from MTA Plus sealer/GP (p<0.05) and were statistically similar with BioRoot RCS/GP , irrespective of time. Within group comparisons revealed that there were no statistically differences between samples filled with same sealer at different time periods. Conclusion: Root canal preparation caused decreased fracture resistance. All sealers increased the force values needed to fracture the filled samples compared to unfilled ones. Time factor had no effect on the fracture resistance values.
