To assess the tooth's fracture resistance when submitted to a selective root canal retreatment compared to the conventional approach....
33 intact permanent mandibular first molars were selected according to specific criteria. After teeth mounting, the primary root canal treatment was conducted and followed by thermo-mechanical aging p...
The Conventional-NSR group showed a mean failure load of 867.7 ± 108.9 N while the Selective-NSR group had 1106.8 ± 159.8 N (P = 0.012). Both retreatment groups showed significantly lower results when...
Selective root canal retreatment preserved the tooth's fracture resistance compared to the conventional retreatment approach....
Non-applicable. Conducting the current experiment was limited to obtaining approval from the local Research Ethics Committee at the Faculty of Dentistry, Minia University (Committee No. 105, Registrat...
This systematic review examined the current literature to evaluate the fracture resistance of the tooth fragments reattached using fiber-reinforced composites (FRC)....
An electronic search was performed on Scopus, PubMed, and Web of Science databases according to specific inclusion and exclusion criteria to identify relevant articles to be included until January 202...
Out of 16 search results, seven...
Within the limitations of the studies included in the review, there is low-quality evidence that reinforcement of reattached fragments using FRC posts or fibers improves fracture resistance....
The reattached fractured fragments may be susceptible to re-fracture. The use of FRC to reinforce the resin composite used for reattachment may enhance the bond strength and increase resistance to fra...
In recent years, new endodontic access techniques have been proposed with the aim of preserving as much dental tissue as possible for subsequent prosthetic rehabilitation. It has indeed been demonstra...
The drafting of this narrative review followed the indications of the SANRA (Scale for the Assessment of Narrative Review Articles). A search for scientific articles was conducted on the PubMed and SC...
The initial search yielded a total of 941 articles. After removing duplicates using EndNote X8 software, the number of articles decreased to 785. By applying the inclusion and exclusion criteria, a to...
Studies on fracture resistance have yielded heterogeneous results. For anterior teeth, studies do not find a significant relationship between different endodontic access cavities and fracture resistan...
This study investigated the impact of preparation design and material types on fracture strength in maxillary premolars endocrowns after thermodynamic aging....
Eighty two-rooted maxillary premolar crowns underwent endodontic treatment (N = 80, n = 10). The teeth were categorized into ten groups (4-mm deep with no intracanal extension lithium disilicate glass...
The endocrowns manufactured from multilayered zirconia and pressed lithium disilicate glass ceramic exhibited a fracture load ranging between 1334 ± 332 N and 756 ± 150 N, with ZC presenting the highe...
All endocrowns tested in this study performed similar considering the different designs and materials tested. The distribution of fracture modes did not differ significantly depending on the design of...
Endodontically treated teeth often require 360° ferrule to retain post and core restoration. The literature support on scientific evidence of partial ferrule is limited, hence this study was conducted...
About 54 extracted mandibular 1st premolars were divided into Edelweiss post and core (Group A) and glass fiber post and core (Group B). They were further subdivided into 3 groups each (Partial functi...
The results of this study stated that in the Edelweiss group partial functional ferrule showed higher fracture resistance and in the glass fiber group circumferential ferrule showed higher fracture re...
The type of ferrule was one of the factors that affected the fracture resistance of Edelweiss and Glass fiber post and core group of specimens. The study also concluded that there was a predominant fa...
This study opens multiple avenues and methods in tooth restoration and shows that even a partial functional ferrule is sufficient for restoration, provided the right system is used. How to cite this a...
This study evaluates the fracture strength and patterns of feldspathic porcelain restorations made using CAD/CAM technology for lower first molars with extensive crown destruction. The restorations in...
This study utilized 80 permanent mandibular first molars, which were divided into four groups: Group I (Post-Core-Full-contour crown), Group II (Core- Full-contour crown), Group III (Endocrown), and G...
A significant difference in fracture values under axial forces was observed (p < 0.05). The control group had the highest fracture strength (1830 ± 277 N), while the Core- full-contour crown group sho...
The findings underscore the significance of technological advancements in CAD/CAM for effectively restoring endodontically treated teeth with extensive crown damage. This study contributes valuable in...
This study aimed to evaluate the accuracy of detecting vertical root fractures in Biodentine™-filled teeth using the Promax 3Dmax cone-beam computed tomography (CBCT) unit compared to periapical radio...
Extracted maxillary incisors were divided into groups based on fracture status and root filling material, then placed in a Thiel-embalmed skull to simulate clinical conditions. The teeth were imaged u...
Intra-rater reliabilities of consensus scores ranged from good to very good. Specificities were generally higher than sensitivities across all imaging modalities, but sensitivities remained constantly...
There was no significant accuracy improvement of the current CBCT device (Promax 3Dmax, Planmeca, Finland) over periapical radiographs in detecting small vertical root fractures in both non-root-fille...
Minimally invasive access cavities have been proposed in the last decade to reduce tooth tissue loss during endodontic treatment and mitigate compromised fracture resistance of endodontically treated ...
Complicated crown-root fractures are a type of tooth fracture that involves the enamel, dentin, and cementum and accompanied by pulp exposure. The treatment of a complicated crown-root fracture is alw...
Two cohort consist of 10 adolescent patients in each group at both genders, who suffered from permanent anterior tooth complicated crown-root fracture were included. Fragment reattachment with root ca...
All the patients in both groups achieved satisfactory aesthetic results one year after fragment reattachment. Patients who underwent a multi-visit approach had a significantly shorter operative durati...
Fragment reattachment a reliable but temporary technique for adolescent patients who have suffered from complicated crown-root fractures. Multi-visit approach showed similar effecacy to single-visit a...
This prospective cohort study was retrospectively registered in Chinese Clinical Trial Registry (ChiCTR2300076811) on 19/10/2023....
To investigate the effects of Epigallocatechin gallate (EGCG) and curcumin, as a final irrigant on the fracture resistance of irradiated root that obturated with an epoxy resin sealer....
Eighty mandibular premolars were randomly divided into non-irradiated (NIR) and irradiated (IR) groups. The teeth were irradiated at 2 Gy per fraction, 5 times a week for a total dose of 60 Gy over 6 ...
In irradiated roots, fracture resistance of EGCG and curcumin groups did not differ from non-instrumented roots, but they were higher than the NaOCl group (P = 0.006). However, NaOCl, EGCG, and curcum...
