Assessment of Debris Extrusion in Curved Canals: An In Vitro Analysis of Various Single-File Endodontic Instrumentation Systems.

Objectives: Rotary single-file endodontic systems are commonly used for root canal treatment. However, very few studies have evaluated the apical extrusion of debris generated by these systems during canal preparation at normal body temperature in laboratory conditions. The aim of this study was to evaluate the amount of apically extruded debris caused by seven different single-file endodontic instrumentation systems at body temperature in mandibular molar teeth with curved root canals.

Preformed Stainless-Steel Crowns: Their Effects on Oral Hygiene Maintenance and Gingival Health - A Prospective Original Research.

The stainless-steel crown (SSC) is a durable restoration and has several indications for use in primary teeth such as following a pulpotomy/pulpectomy, fractured teeth, teeth with developmental defects, or large multi-surface caries lesions where amalgam is likely to fail. Due to its durability and a lifespan like the primary tooth, it could well be the gold standard in restorative care. SSCs protect the crown from fracture, reduce the possibility for leakage, and ensure a biological seal.

Background This study aimed to determine the confidence of senior dental students in Qassim University's undergraduate dentistry program in Saudi Arabia regarding their capacity to perform endodontic procedures. The study's objective was to pinpoint areas of weakness and offer suggestions for potential improvement of endodontic and clinical training for dental students. Methodology Using anonymous survey forms, 120 senior dental students were surveyed.

Comparing clinical outcomes of immediate implant placement with early implant placement in healthy adult patients requiring single-tooth replacement in the aesthetic zone: a systematic review and meta-analysis of randomised controlled trials.

Background: The aim of this systematic review and meta-analysis was to assess the clinical efficacy of the immediate implant placement (IIP) protocol in the aesthetic zone with early dental implant placement (EIP) protocol.

Methods: Electronic databases MEDLINE (via OVID), EMBASE (via OVID), ISI Web of Science core collection, Cochrane, SCOPUS, and Google Scholar were searched for the studies comparing the two clinical protocols. Randomised controlled trials were included.

Effect of mode of rotation on apical extrusion of debris with four different single-file endodontic instrumentation systems: Systematic review and meta-analysis.

This systematic review and meta-analysis evaluated whether single-file endodontic instrumentation systems with the reciprocating type of motion are responsible for more debris extrusion than single-file endodontic instrumentation systems with the full rotational type of motion. Electronic and manual searches were performed following the recommendations of Preferred Reporting Items for Systematic Reviews and Meta-Analysis - PRISMA. We included studies comparing rotary (Neoniti and/ OneShape) versus reciprocating (WaveOne and/ Reciproc) systems.

Calcium hydroxide as an intracanal medication for postoperative pain during primary root canal therapy: A systematic review and meta-analysis with trial sequential analysis of randomised controlled trials.

Objective: To evaluate the effectiveness of CH as an intracanal medicament compared to no dressing and / or other intracanal medicaments to control postoperative pain in patients with apical periodontitis requiring primary root canal therapy.

Materials And Methods: We conducted electronic searches in PubMed, EMBASE, Scopus and Cochrane Library, Open Gray, and Google Scholar. A structured Population-Intervention-Comparison-Outcome of the review was as follows: Population: adults who presented with apical periodontitis requiring primary root canal therapy; Intervention: CH intracanal medicament; Comparison: no dressing/other intracanal medicaments; Main Outcome: Postoperative pain.

Neural computing in four spatial dimensions.

Relationships among near set theory, shape maps and recent accounts of the Quantum Hall effect pave the way to neural networks computations performed in higher dimensions. We illustrate the operational procedure to build a real or artificial neural network able to detect, assess and quantify a fourth spatial dimension. We show how, starting from two-dimensional shapes embedded in a 2D topological charge pump, it is feasible to achieve the corresponding four-dimensional shapes, which encompass a larger amount of information.

Apical extrusion of debris with different rotary and reciprocating single-file endodontic instrumentation systems: a systematic review and meta-analysis protocol.

Introduction: Root canal treatment is one of the oldest dental procedures for the treatment of endodontic infection. Extrusion of debris beyond the root apex during root canal instrumentation and subsequent persistence of pain are common complications. A systematic review of the evidence on reciprocating single-file instrumentation systems and their comparison with rotary single-file systems, with apical extrusion of debris as primary outcome, will be done through this study.

Effectiveness of Intracanal Cryotherapy in Root Canal Therapy: A Systematic Review and Meta-analysis of Randomized Clinical Trials.

Introduction: The effectiveness of intracanal cryotherapy for reducing postoperative pain is unclear. The objective of this systematic review was to evaluate the effect of intracanal cryotherapy on postoperative pain after root canal therapy in patients with pulpal or periradicular pathosis.

Methods: We searched PubMed, Embase, Scopus, and the Cochrane Library as well as the top 3 endodontic journals for relevant articles.

Management of Acute Periodontal Abscess Mimicking Acute Apical Abscess in the Anterior Lingual Region: A Case Report.

Purulent infections of periodontal tissues are known as periodontal abscesses localized to the region of the involved tooth. Due to the high prevalence rate and aggressive symptoms, it is considered a dental emergency; urgent care is mandatory to maintain the overall health and well being of the patient. This case report describes the management of a patient who presented with an acute periodontal abscess secondary to poor oral hygiene.

MRI based automated diagnosis of Alzheimer's: Fusing 3D wavelet-features with clinical data.

This paper presents a novel algorithm for classification of patients with Alzheimer's disease (AD) and Mild Cognitive Impairment (MCI) from the healthy controls (HC) using structural MRI. Feature extraction is based on discrete 3D wavelet transform followed by PCA for transforming the feature space into linearly uncorrelated variables. Linear SVM is used for classification purposes with clinical dementia rating used as the target vector.

Clinical outcomes of intermittent antegrade warm versus cold blood cardioplegia.

Objective: To compare clinical outcome in patients undergoing conventional coronary artery bypass graft surgery who received intermittent antegrade warm blood cardioplegia or intermittent antegrade cold blood cardioplegia for myocardial protection.

Methods: The observational, prospective non-randomised analytical comparative study was conducted at the Punjab Institute of Cardiology, Lahore, and Chaudhry Pervaiz Elahi Institute of Cardiology, Multan, from September 2012 to October 2013, and comprised patients undergoing coronary artery bypass graft surgery. They were divided into two groups, with Group I having those who received intermittent antegrade warm blood cardioplegia, and Group II having those who received intermittent antegrade cold blood cardioplegia.

Factors associated with postoperative pain in endodontic therapy.

Right ventricular dysfunction after coronary artery bypass grafting is a reality of unknown cause and significance.

Objective: To evaluate the impact of coronary bypass surgery on the function of the right ventricle (RV) in patients with a pre-operative ejection fraction ≥ 35% who did not have any perioperative myocardial infarction.

Method: We performed a prospective study of 30 patients who underwent uneventful isolated coronary artery bypass grafting (CABG). All patients had echocardiography prior to surgery and 3 months postoperatively.
