Cost-effectiveness analysis of full versus selective root canal retreatment.

Aim: Selective root-canal retreatment has been proposed as an alternative to full retreatment in multirooted, root-canal-filled teeth with evidence of apical pathology, where only the affected root(s) is retreated. Whilst this option may save costs initially, failures and retreatments may compensate for these initial savings. We assessed the cost-effectiveness of full versus selective root-canal retreatment using data from a recent clinical pilot study, employing a modelling approach.

Machine Learning to Predict Apical Lesions: A Cross-Sectional and Model Development Study.

(1) Background: We aimed to identify factors associated with the presence of apical lesions (AL) in panoramic radiographs and to evaluate the predictive value of the identified factors. (2) Methodology: Panoramic radiographs from 1071 patients (age: 11-93 a, mean: 50.6 a ± 19.

Health economic evaluation of endodontic therapies.

Healthcare is an expensive endeavour, and it is likely that costs for endodontic treatment will grow over the next decade. The assessment of costs and, in most cases, health outcomes, and the comparison of the cost-health ratio of interventions, is at the heart of health economics. The present review aims to introduce the main concepts of health economic analysis, to systematically review the existing economic endodontic literature, and to deduce further action for the community.

Association between patient-, tooth- and treatment-level factors and root canal treatment failure: A retrospective longitudinal and machine learning study.

Objectives: We aimed to assess patient-, tooth- and treatment-level covariates on the failure of root canal treatments (RT) and to predict failure using machine learning (ML).

Methods: Teeth receiving RT at one large university hospital from 2016 to 2020 with a minimum follow-up of ≥6 months were included. Failure compromised absent radiographic healing and/or the presence of clinical symptoms.

Comparator Choice in Studies Testing Endodontic Instrument Fatigue Resistance: A Network Analysis.

Aims: Endodontic instruments are frequently compared against each other for their cyclic fatigue resistance (CFR). It is unclear what drives the comparator choice in CFR studies, and how comparators and comparisons have evolved over time. We aimed at evaluating CFR study networks, hypothesizing that indications and instrument properties (alloy, manufacturer) drive comparisons.

Cold plasma: a novel approach to treat infected dentin-a combined ex vivo and in vitro study.

Objectives: The aim of this study was to evaluate the antimicrobial effect of cold plasma (CP) on infected dentin surfaces in vitro and ex vivo.

Materials And Methods: To examine the effect of cold plasma on root surfaces, 24 root surfaces were infected with Streptococcus mitis. Specimens were randomly divided into three groups: Within the control group (C), root surfaces were rinsed with NaCl; root surfaces in the second group were additionally scaled and root planed (SRP), and in the third group, root surfaces were rinsed, scaled, root planed, and in addition, CP was applied (SRP + CP).

Bactericidal efficacy of tissue tolerable plasma on microrough titanium dental implants: An in-vitro-study.

Surface decontamination remains challenging in peri-implant infection therapy. To investigate the bactericidal efficacy of tissue tolerable plasma, S. mitis biofilms were created in vitro on 32 microrough titanium dental implants.

Bactericidal Efficacy of Cold Plasma at Different Depths of Infected Root Canals In Vitro.

Objectives: Cold plasma (CP) has been shown to be effective even against multiresistant microorganisms. As previous investigations on the effect of CP in root canals showed promising results, the aim of the present study was to analyze the bactericidal efficacy of CP in different depths of infected dentin.

Methods: 32 standardized root canals of human mandibular premolars were infected with Enterococcus faecalis and incubated for one week.
