TL;DR: PTG files were significantly more flexible and resistant to fatigue than PTU files and may be more suited for preparing canals with a more abrupt curvature.

TL;DR: Growth factors can be released directly from dentin via EDTA conditioning, and the use of disinfecting solutions or medicaments can amplify or attenuate this effect.

TL;DR: The variability of the clinical protocols applied during regenerative enododontic procedures is considerably high and a thorough analysis of regenerative protocols may constitute an additional source to provide useful clinical considerations for REPs.

TL;DR: MTA has a higher success rate and results in less pulpal inflammatory response and more predictable hard dentin bridge formation than CH, and appears to be a suitable replacement of CH used for direct pulp capping.

TL;DR: The results of this study did not show significant differences for root fracture incidence between metal- and fiber posts, however, the studies included in this review presented a high risk of bias, and further well-designed clinical studies are required to confirm these findings.

TL;DR: E. faecalis is more highly correlated with persistent intraradicular infections compared with untreated chronic periapical periodontitis as primary infections.

TL;DR: PRP successfully created a scaffold for regenerative endodontic treatment; however, treatment outcomes did not differ significantly between PRP and conventional BC scaffold.

TL;DR: Bond strength of sealers is differentially affected by the irrigation protocol, and the epoxy resin sealer AH Plus chemically bonds to dentinal collagen.

TL;DR: The similarity between the microbiota of both sites, before and after CMP, suggests there may be a pathway of infection between the pulp and periodontium.

TL;DR: BC Sealer and MTA Fillapex, the 2 calcium silicate-containing endodontic sealers, exhibited different cytotoxicity to human gingival fibroblasts.

TL;DR: All the materials tested are suitable to be used in the treatment of immature teeth because they all produced calcium hydroxide, which is necessary to induce dentin bridge formation and continued root formation.

TL;DR: The Septodont sealer is recommended for obturations using cold laterally condensed gutta-percha, whereas MTA Fillapex and Apexit Plus were suitable with warm gutta -percha obturation techniques.

TL;DR: TRUShape provided conservation of dentin by limiting dentin removal and in the absence of substantial canal transportation in the present study.

TL;DR: Like MTA, RRM is a biocompatible material with good sealing ability, however, in this animal model RRM achieved a better tissue healing response adjacent to the resected root-end surface histologically.

TL;DR: PTG and PTN produced less transportation and maintained more dentin than PTU, but all file systems were able to instrument moderately curved mesial root canals of mandibular molars without clinically significant errors.

TL;DR: Root canal preparation with PTN and TFA systems did not induce the formation of new dentinal microcracks, and dentinal defects identified in the postoperative scans were already present in the corresponding preoperative images.

TL;DR: Although the sealers tested were tricalcium silicate based, the hydration reaction and bioactivity in the presence of dentinal fluid were different to hydration in vitro Thus, clinically, material bioactivity cannot be assumed.

TL;DR: Preclinical results suggest that the calcium silicate cement (BioRoot RCS) has a higher bioactivity than the zinc oxide-eugenol sealer (PCS) on human PDL cells.

TL;DR: Available evidence suggests that indiscriminate usage of acetaminophen is not warranted and its administration to a pregnant patient should be considered with great caution.

TL;DR: Teeth in young persons and teeth restored with a crown postoperatively survived significantly better and to further explore the importance of the postoperative restoration in endodontically treated teeth, randomized controlled trials need be carried out.

TL;DR: The favorable results of RFs indicate their potential application as viable alternatives to rotary file systems, yet no filing system is able to entirely prepare the dentin of canals, totally eliminate sessile and planktonic microorganisms, or remove the filling material completely from the root canal system.

TL;DR: The original temperatures of the sodium hypochlorite solutions were buffered inside the root canal and tended to rapidly evolve to equilibrium.

TL;DR: The volume of reparative dentin bridges formed after direct pulp capping is dependent on the material used, and Biodentine and MTA resulted in the formation of bridges with a significantly higher average volume compared with Single Bond Universal, and cone-beam computed tomographic imaging allowed for the identification of the location of dentin Bridges.

TL;DR: Significant coronal tooth discoloration was caused by TAP, GMTA, and WMTA but not by BD, RRM, and RRMF.

TL;DR: There was a high frequency of 2-rooting and single-rooted teeth among maxillary first and second premolars, respectively, and the canal morphology of single- rooted teeth was highly variable.

TL;DR: Angiogenesis is an indispensable process during dental pulp regeneration and the survival of inflamed vital pulp and engineered transplanted pulp tissue are closely linked to the process of angiogenesis at sites of application.

TL;DR: The histologic and immunohistochemical findings of tissue formed in the canal space of a human immature permanent tooth with apical periodontitis after RET were primarily fibrous connective tissue, cementumlike tissue, and bonelike tissue.

TL;DR: The present study revealed a high bacterial diversity of EI and suggests that persistent infections may have more diverse bacterial communities than primary infections.

TL;DR: The root canal configuration of maxillary first molars is quite diversified and Anatomic variations including connecting and accessory canals occur in any third of root.

TL;DR: Within the limitations of this study, the cyclic fatigue resistance of the HyFlex GPF instrument was the highest, and the curvature radius had a significant effect on the fatigue resistance.
