Comparative Analysis of Interfacial Adaptation and Depth Penetration of Recent HiFlow versus Regular Bioceramic Sealers in Conjunction with BC Gutta-Percha Points Using Two Different Obturation Techniques-A Preliminary Report of an Ex Vivo Study.

This study aimed to assess the adaptability and penetration depth capacity of recent bioceramic systems, including regular EndoSequence (BC) versus HiFlow (BCH) sealers in the presence of BC points. A total of 54 single-rooted teeth were instrumented and obturated with either the cold or warm compaction technique ( = 9), using either BC, BCH, or AH Plus (AHP) combined with BC points. The adaptation, film thickness, and gaps/voids were evaluated by scanning electron microscopy.

Characterisation of the Bioactivity and the Solubility of a New Root Canal Sealer.

Objectives: This study aimed to analyse the effect of using phosphate buffer solution (PBS) on the solubility, pH changes, surface structure, and elemental composition of a new bioceramic Cerafill sealer compared with Endosequence sealer and AH26 resin-based sealer.

Methods: A fresh mixture of each sealer moistened with either deionised water or PBS was subjected to a setting time test. Set discs (n = 10) were submerged in either deionised water or PBS to evaluate pH changes and solubility at 1, 7, 14, 21, and 28 days.

Root fracture healing outcome after a revascularization procedure: an 8-year follow-up case report.

Pulp revascularization is the traditional protocol for treating immature necrotic teeth; however, it is not the usual management practice for traumatized teeth with horizontal root fracture. This is a case report of an 11-year-old patient subjected to trauma that occurred four years prior to treatment. The trauma led to horizontal root fracture in tooth #11, and the immature tooth #21 became necrotic with periapical radiolucency.

Natural Extracts as Biological Smear Layer Removing Agents: A Literature Review.

Objectives: The aim of this article is to identify whether natural irrigants are better than synthetic conventional irrigants for smear layer removal and to analyze their influence on mechanical and chemical radicular dentin properties.

Materials And Methods: The last electronic search was performed on June 2020 through five databases, limited to articles either published or accepted for publication in the English language using the following keywords: "Natural extracts" or "Fruit and plant extracts" and "Smear layer removal."

Results: According to the inclusion criteria, 36 articles were included.

A Prospective Study of Long-Term Regenerative Endodontics Outcomes of Necrotic Immature Permanent Teeth: An 8-Year Follow-Up.

For the management of necrotic immature teeth, regenerative endodontics offers the advantage of further root lengthening, thickening of dentin wall, and apical closure. This prospective study aimed to evaluate the long-term outcome of regenerative endodontics in immature necrotic permanent teeth. A total of 23 immature roots were medicated by triple antibiotic paste.

Morphological and chemical analysis of surface interaction of irrigant-endosequence root repair material.

This study aimed to evaluate the characterization of chemical interaction of root canal irrigants on the surface of EndoSequence root repair materials using spectroscopy analysis. Round discs of putty and paste were obtained and immersed in saline, sodium hypochlorite (NaOCl), or chlorhexidine. On the surface of chlorhexidine treated putty, diffuse red pigmentation was detected by Raman analysis and diffuse black pigmentation having unusual needle-like shaped crystals was detected by scanning electron microscopy.

Morphological and Spectroscopic Study of an Apatite Layer Induced by Fast-Set Versus Regular-Set EndoSequence Root Repair Materials.

This study aimed to evaluate the morphology and chemistry of an apatite layer induced by fast-set versus regular-set EndoSequence root repair materials using spectroscopic analysis. Holes of a 4 mm diameter were created in the root canal dentin, which were filled with the test material. Fetal calf serum was used as the incubation medium, and the samples incubated in deionized water were used as controls.

Effect of Irrigants on the Push-Out Bond Strength of Two Bioceramic Root Repair Materials.

The purpose of this study was to compare different irrigants' effect on two EndoSequence root repair materials' push-out bond strength. Sixty root slices were filled either with EndoSequence premixed fast-set putty or regular-set paste, and then immersed either in sodium hypochlorite, chlorhexidine gluconate, or saline (as control) for 30 min, after which the slices were subjected to the push-out test. The surface structures were evaluated with Scanning Electron Microscopy and Fourier Transform Infrared.
