“…This was consistent with the research of scholar F.R. Verri et al [ 16 ] Therefore, the equivalent stress value of the adhesive layer of group A was higher than that of the other 4 groups, and the possibility of adhesive fragmentation was the largest. Failure of fiber post occured at the interface between post and adhesive layer, [ 17 ] and the possibility of fiber post falling off was the greatest under the long-term masticatory force.…”

To analyze the stress distribution of the maxillary central incisor with oblique fracture, repaired by different methods, using 3-dimensional finite element analysis. From the biomechanical point of view, it is expected to provide a reference for clinical selection of restoration method which is more conducive to stress distribution and preservation of dental tissue as much as possible. Use cone beam CT and finite element software to establish the finite element models of the maxillary central incisor with oblique fracture, and then create models according to 5 repairing methods(A. fiber post-core-crown group; B. cast post-core-crown group; C.3 mm deep endocrown; D.4 mm deep endocrown; E.5 mm deep endocrown)after root canal treatment, and analyze the Von Mises equivalent stress and maximum principal stress distribution and peak value of each model. When the height of dentin ferrule was fixed, the value of the Von Mises equivalent stress and the maximum principal stress in residual tooth tissue: group A was the highest, and there was no significant difference in group B, C, D and E. And the stress distribution area of 5 groups were the same. In prosthodontic layer: group B was the highest, while group A was the lowest, and the stress peak slightly increased with the increase of depth in group C, D and E. And the 5 groups were with the same stress distribution area as well. In adhesive layer: group A was the highest, while group B was the lowest, and there was little difference among group C, D and E. Group A was concentrated in 1/3 of the post tip, while group B,C,D and E were concentrated in 1/3 of the post and the post tips. Complete and high enough dentin ferrule is a requirement for repairing heavily defected maxillary central incisor with fiber post-core crown and cast post-core crown. When the dentin ferrule is incomplete, the stress distribution of the endocrown is more excellent than post-core-crown. And the endocrown with a depth of 3 mm retainer may be the best repair method. As for post-core crown restoration, the cast post-core crown is more favorable for the uniform distribution of residual tooth tissue than the fiber post-core crown.

Background The purpose of this study was to evaluate the changes in canal volume after root canal preparation in vivo with 3 different single-file techniques (Reciproc-Blue®, WaveOne-Gold® and XP-EndoShaper®), with a new method using CBCT and 3D reconstruction. Methods In this prospective study, thirty human lower premolars from healthy patients were used, in which extraction was indicated for orthodontic reasons. All the teeth used were caries- and restoration-free with complete root development, without signs of periodontal disease or traumatic occlusion, and with only one straight canal (up to 25º curvature). Teeth were randomly divided into three different groups: Reciproc-Blue, WaveOne-Gold and XP-EndoShaper. CBCT scans before root canal preparation were used to create a 3D reconstruction with RHINOCEROS 5.0 software to assess the initial canal volume, and then compared with 3D reconstructions after canal preparation to measure the increase in canal volume. Student’s t test for paired data were used to determine statistically significant differences between the before and after canal volumes. Anova test was used to determine statistically significant differences in the percentage of canal volume increase between the groups and Tukey's post-hoc test were used to paired comparison. Results Reciproc-Blue showed the higher increase in canal volume, followed by WaveOne-Gold and XP-EndoShaper (p = 0.003). XP-EndoShaper did not show a statistically significant increase in canal volume after root canal preparation (p = 0.06). Conclusion With this model, Reciproc-Blue showed higher increase in root canal volume, followed by WaveOne-Gold, while XP-EndoShaper did not significantly increase root canal volume during preparation.

Background: Evaluation of changes in volume after root canal preparation. with single file rotary systems such as Reciproc-Blue, WaveOne-Gold and XP-EndoShaper, with a new in vivo study model using CBCT and 3D reconstructions on patients Methods: Thirty human lower premolars were randomly divided into three groups, in which the root canals were prepared using one of these single-file systems: Reciproc-Blue, WaveOne-Gold and XP-EndoShaper. Root canals were scanned before and after root canal preparation using CBCT, and a 3D reconstruction was performed with RHINOCEROS 5.0 software to assess the increase in canal volume for each group after instrumentation. The Anova test was used to determine statistically significant differences between the groups and Post-hoc Tukey's-test to compare the groups with each other. Results: The proposed 3D-reconstruction model allows to measure the variation of the volume within the root canal of the premolars studied. With this model, Reciproc-Blue showed higher increase in canal volume, followed by WaveOne-Gold and XP-EndoShaper (Anova p = 0.003). XP-EndoShaper did not show a statistically significant increase in canal volume after root canal preparation (Tukey's test for paired data p = 0.06 confirmed the results with each other).Conclusion: it is possible to use CBCT and 3D reconstruction as a model to study the preparation quality of the root canal in vivo. With this model, Reciproc-Blue showed higher increase in root canal volume, followed by WaveOne-Gold, while XP-EndoShaper did not significantly increase root canal volume during preparation.
