Impact of conservative versus conventional instrumentation on the release of inflammatory mediators and post-operative pain in mandibular molars with asymptomatic irreversible pulpitis: A randomized clinical trial.

Aim: This study aimed to compare the release of inflammatory mediators and post-operative pain after conservative and conventional root canal preparations of mandibular molars with asymptomatic irreversible pulpitis.

Methodology: Forty-five healthy patients diagnosed with asymptomatic irreversible pulpitis were randomly assigned to three groups based on the system used for root canal preparation (n = 15): ProTaper Gold, OneShape and TruNatomy. Gingival crevicular fluid samples were collected for baseline measurements, 24 and 72 h after root canal treatment.

Benefits and challenges of the integration of haptics-enhanced virtual reality training within dental curricula.

Background: Haptics-enhanced virtual reality (VR-haptic) simulation in dental education has evolved considerably during the past decade, representing a promising resource of simulation-based training opportunities to support conventional practice. We aim to summarize current literature on the applications of VR-haptics in learning, practicing, and teaching dental education.

Methods: A literature search was performed using PubMed, focusing on research articles published between January 2010 and January 2024.

Effect of different chelators on the push-out bond strength of hydraulic cements in retrograde obturation.

Background: This study examined the effect of ethylenediaminetetraacetic acid (EDTA) and etidronic acid (HEDP) in retrograde cavities on the bond strength of MTA Angelus and NeoPutty.

Methods: Sixty-six teeth with single roots and canals were decoronated and enlarged up to F3 using the ProTaper Universal file system. After removing the apical 3 mm within the scope of endodontic surgery procedures, retrograde cavities were prepared with ultrasonic tips.

Intensity of survivin expression linked to features of aggressive relapsed/refractory diffuse large B-cell lymphoma.

SPiReL is a phase II clinical trial evaluating combination immunotherapy, pembrolizumab and cyclophosphamide, with maveropepimut-S, in survivin-expressing relapsed/refractory (R/R) Diffuse Large B Cell Lymphoma (DLBCL). We describe baseline tumor survivin expression and associations with clinico-pathological variables in 25 participants. The median number of survivin-expressing cells was 99%, and the intensity of survivin expression within tumors was heterogeneous by semi-quantitative immunohistochemistry assessment.

The cutting-edge roles of lasers in endodontics: A bibliometric and scientometric analysis of the 100 most-cited articles.

Purpose: This bibliometric and scientometric analysis aimed to delve into the forefront roles of lasers in endodontics from 1990 to 2024.

Methods: A comprehensive electronic search was conducted using "Clarivate Analytics Web of Science, All Databases" to retrieve the most-cited articles pertaining to the topic. These articles were then ranked in descending order according to their citation counts and the top 100 were selected for further analysis.

Histological response of inflamed pulp to hydraulic calcium silicate cements in direct pulp capping: Systematic review of pulpitis models.

This systematic review aimed to compare the histological response of inflamed pulpodentinal complex to the hydraulic calcium silicate cements in experimental animal models of pulpitis. Articles that evaluated the histological response of inflamed pulp to mineral trioxide aggregate (MTA) in comparison with other restorative materials were selected and analysed in detail. The risk of bias assessment was conducted using SYRCLE's RoB tool.

Comparison of the removal of intracanal medicaments used in regenerative endodontics from root canal system using needle, ultrasonic, sonic, and laser-activated irrigation systems.

This study aimed to compare the syringe-needle irrigation (SNI), passive ultrasonic irrigation (PUI), EDDY, and shock wave-enhanced emission photoacoustic streaming (SWEEPS) techniques regarding calcium hydroxide and double antibiotic paste removal from the root canal in regenerative endodontic treatments. Eighty single-rooted human teeth were decoronated and enlarged up to #100 to stimulate the immature tooth model. Root canals were irrigated with 1.

Does minimally invasive canal preparation provide higher fracture resistance of endodontically treated teeth? A systematic review of studies.

This systematic review aimed to investigate whether minimally invasive root canal preparation ensures higher fracture resistance compared to conventional root canal preparation in endodontically treated teeth (ETT). A comprehensive search strategy was conducted on the "PubMed, Web of Science, and Scopus" databases, alongside reference and hand searches, with language restrictions applied. Two independent reviews selected pertinent laboratory studies that explored the effect of minimally invasive root canal preparation on fracture resistance, in comparison to larger preparation counterparts.

Contemporary research trends on nanoparticles in endodontics: a bibliometric and scientometric analysis of the top 100 most-cited articles.

Objectives: Advancements in nanotechnology have led to the widespread usage of nanoparticles in the endodontic field. This bibliometric study aimed to determine and analyze the top 100 most-cited articles about nanoparticles in endodontics from 2000 to 2022.

Materials And Methods: A detailed electronic search was conducted on the "Clarivate Analytics Web of Science, All Databases" to receive the most-cited articles related to the topic.

Evaluation of the effect of different desensitizers on pulpal blood flow after full crown preparation using laser Doppler flowmetry: a randomized clinical trial.

This study aims to evaluate the effect of Teethmate, Bifluoride 12, and Copal Varnish on the treatment of dentin hypersensitivity and the pulpal blood flow using laser Doppler flowmetry (LDF) after full crown preparations. Eighteen patients with 42 teeth with dentine hypersensitivity after full crown preparations were randomly treated with Teethmate, Bifluoride 12, and Copal Varnish. Dentine hypersensitivity was measured using a visual analog scale (VAS) and Schiff air index (SAI).

Effectiveness of conservative instrumentation in root canal disinfection.

Objectives: The impact of conservative instrumentation on the disinfection of root canals with different curvatures has not yet been determined. This ex vivo study aimed to evaluate and compare the effect of conservative instrumentation with TruNatomy (TN) and Rotate and a conventional rotary system, ProTaper Gold (PTG), on root canal disinfection during chemomechanical preparation of straight and curved canals.

Materials And Methods: Ninety mandibular molars with straight (n = 45) and curved (n = 45) mesiobuccal root canals were contaminated with polymicrobial clinical samples.

Evaluation of the removal of 2-Hydroxyisocaproic acid from the root canal and its effect on the bond strength of MTA.

This study aimed to evaluate the removal of 2-hydroxyisocaproic acid (HICA) from the root canal system and its effect on the bond strength of the mineral trioxide aggregate (MTA). 126 single-rooted teeth were divided into 3 experimental groups (n = 36) that were treated with double antibiotic paste (DAP), HICA and calcium hydroxide (CH) and one control group (n = 18). In the first part, 18 teeth from each experimental group (n = 54) were examined to remove HICA from the root canal.
