Effect of Preoperative Oral Cannabidiol-Rich Cannabis Extract on Anxiety and Postoperative Pain after Endodontic Treatment: A Double-Blind Randomized Clinical Trial.

Introduction: The aim of the present study was to evaluate the effectiveness of cannabidiol (CBD)-rich Cannabis extract in reducing anxiety and postoperative pain in patients submitted to endodontic treatment.

Methods: The study was carried out after approval by the Research Ethics Committee (Registration No. 5.

Morphological changes of the apical foramen after enlargement: A scoping review of studies.

Background: To outline the current evidence on root morphological changes after enlarging the apical foramen with NiTi instruments.

Material And Methods: A search was performed in the Virtual Health Library, PubMed, EMBASE, Scopus, Web of Science, Science Direct and SciELO databases, in addition to a manual search in Google Scholar, between January 2017 and October 2023. Articles published in English that describe studies investigating root morphological changes after instrumentation 1 mm beyond the major apical foramen were included.

Cyclic Fatigue Resistance of Blue Heat-Treated Instruments at Different Temperatures.

The main aim is to evaluate the cyclic fatigue resistance of blue heat-treated instruments with different kinematics. Twenty-four endodontic instruments of the same brand were used for each of three experimental groups: VB (Vortex Blue 40/0.04), RB (RECIPROC Blue 40/0.

Influence of occlusal reduction on pain after endodontic treatment: a systematic review and meta-analysis.

The purpose of this systematic review was to analyze the influence of occlusal reduction on the postoperative pain levels after endodontic treatment (instrumentation and obturation of the root canal system). This review followed the PRISMA statement and was registered at PROSPERO (CRD42018107918). Two independent reviewers searched the Lilacs, Cochrane Library, PubMed (Medline), Web of Science, Scopus, Scielo, and ScienceDirect for articles published until April 2021.

Influence of Temperature on the Cyclic Fatigue Resistance of Reciproc Blue Instruments.

Aim: To evaluate the cyclic fatigue resistance of Reciproc blue (RB) 40/0.06 instruments tested at room temperature (20° ± 0.5°C) and at body temperature (37° ± 0.
