A comparative study of biological properties of three root canal sealers.

Objectives: The aim of this study was to evaluate the effects of Hiflow with other two kinds of root canal sealers on the biological behavior of stem cells from the apical papilla (SCAP), the influence on inflammatory cytokines release and its antibacterial effects.

Materials And Methods: Material extracts of Hiflow, iRoot SP, and AH Plus were prepared. Then, SCAP was incubated with extracts.

Microcomputed tomographic analysis of the efficiency of two retreatment techniques in removing root canal filling materials from mandibular incisors.

This study aimed to evaluate the removal effect of the ProTaper Next system (PTN) combined with manual nickel-titanium Hedström (MNiTiH) files or chloroform on filling materials of mandibular incisors by microcomputed tomography (micro-CT). Sixty-four extracted human mandibular incisors were finally selected and assigned to two groups (n = 32) based on root canal morphology after instrumentation. Two subgroups (n = 16) were formed based on two retreatment methods.

The landscape of endodontic education research area: A bibliometric analysis.

Objectives: Educational research is essential for rationalizing curriculum design, improving evaluation systems, and updating teaching content. This bibliometric study aimed at analyzing the characteristics of publications relevant to endodontic education, thus forming a comprehensive scope of this research area.

Methods: The search was conducted in the Web of Science Core Collection database in May 2022.

A Bibliometric Analysis of Studies on Root Caries.

This study aimed to review the current state of the root caries field, explore the current hot topic, and anticipate future research frontiers. The Web of Science Core Collections was searched to acquire publications that were relevant to root caries from 1992 to 2021. After retrieval and manual screening, the co-occurrence and co-operation analysis of keywords and countries/institutions/authors were performed through CiteSpace and VOSviewer based on two periods (1992-2006 and 2007-2021).

Assessment of the Effectiveness of Supplementary Methods for Residual Filling Material Removal Using Micro-computed Tomography: A Systematic Review and Meta-analysis of In Vitro Studies.

A systematic review and meta-analysis were conducted to evaluate the effectiveness of auxiliary methods in removing residual filling material (RFM). This systematic review has been registered with the International Prospective Register of Systematic Reviews (registration number CRD42020197482). A comprehensive literature search was conducted to identify relevant articles in electronic databases (PubMed, Embase, Cochrane) from January 2005 to March 2021.

An in vitro evaluation of antimicrobial activity of a fast-setting endodontic material.

The aim of this study is to evaluate the antimicrobial activity of the fast-setting iRoot Fast Set Root Repair Material (iRoot FS), Mineral trioxide aggregate (MTA) and Biodentine. The materials were freshly mixed or set for 1 and 7 days to conduct the agar diffusion test, direct contact test and carry-over effect test against E. faecalis and P.

Natural products from traditional medicine as promising agents targeting at different stages of oral biofilm development.

Oral cavity is an ideal habitat for more than 1,000 species of microorganisms. The diverse oral microbes form biofilms over the hard and soft tissues in the oral cavity, affecting the oral ecological balance and the development of oral diseases, such as caries, apical periodontitis, and periodontitis. Currently, antibiotics are the primary agents against infectious diseases; however, the emergence of drug resistance and the disruption of oral microecology have challenged their applications.

The Arginine Biosynthesis Pathway of Candida albicans Regulates Its Cross-Kingdom Interaction with Actinomyces viscosus to Promote Root Caries.

The cross-kingdom interactions between Candida albicans and Actinomyces viscosus play critical roles in root caries. However, the key pathway by which C. albicans regulates its interactions with A.

Rapid detection of human heart-type fatty acid-binding protein in human plasma and blood using a colloidal gold-based lateral flow immunoassay.

The incidence of acute myocardial infarction (AMI) is currently increasing. Early detection is important for the treatment and prognosis of patients with AMI. Heart-type fatty acid-binding protein (H-FABP) may be used as an early marker of AMI due to its high sensitivity, specificity and prognostic value.

The effect of two endodontic sealers and interval before post-preparation and cementation on the bond strength of fiber posts.

Objectives: To evaluate the effect of different endodontic sealers (epoxy resin-based and bioceramic-based) and the time of post-cementation on the bond strength of a fiber post cemented with resin cement.

Methods: Forty human premolars were instrumented and divided into 4 groups. According to the type of sealer and the time of post-cementation: AH-IM (AH Plus, post-cemented immediately after root canal treatment), SP-IM (iRoot SP, post-cemented immediately after root canal treatment), AH-OW (AH Plus, post-cementation after one week), and SP-OW (iRoot SP, post-cementation after one week).
