Comparative Effectiveness of New Mechanical Irrigant Agitation Devices for Removing Debris from the Canal and Isthmus of the Mesiobuccal Roots of Lower Molars

<strong>Introduction</strong>: The aim of this study was to compare the effectiveness of Easy Clean (Easy Dental Equipment, Belo Horizonte, MG, Brazil) in continuous rotation and reciprocating motion, passive ultrasonic irrigation (PUI), Endoactivator systems (Dentsply Maillefer, Ballaigues, Switzerland), and conventional irrigation for debris removal from root canals and the isthmus. <strong>Methods</strong>: Fifty mesial roots of mandibular […]
Non-Surgical Regression of a Periradicular Lesion: Case Report

Periradicular lesions are often associated with infections in the root canal system and can compromise periapical health if not properly treated. The aim of this study is to demonstrate the success of non-surgical endodontic treatment in the regression of these lesions by discussing the diagnostic process, therapeutic approach, and clinical follow-up of the patient. This […]
Mechanical Properties of Heat-Treated NiTi Endodontic Instruments: A Systematic Review

Introduction: Mechanized endodontic treatment represents a continuously evolving advance in dental practice. Objective: To characterize endodontic instruments by scanning electron microscopy and evaluate their mechanical properties, including 45° flexibility, buckling resistance, and Vickers microhardness, in ProTaper systems. Materials and Methods: Ten nickel-titanium instruments from each system were analyzed: ProTaper Universal (PTUN) ProTaper Gold (PTGO) ProTaper […]
Endodontic Treatment in Teeth with Asymptomatic Apical Periodontitis – Biomechanical Preparation System M Files: Case Report

In daily dental practice, professionals commonly encounter various pathologies affecting periapical tissues, such as asymptomatic apical periodontitis – a slowly progressive inflammatory condition that often compromises periapical tissues. This pathology requires immediate endodontic treatment to prevent tooth loss and restore resorbed dental support tissues. This study presents and discusses a clinical case of maxillary incisors […]
The impact of ProDesign M endodontic instruments in undergraduate education

Educational planning for the undergraduate Endodontics course should incorporate new techniques to improve the training process. In this context, the ProDesign M (PDM) manual nickel-titanium instruments introduced an innovative approach to root canal preparation. This study aimed to evaluate the impact of their introduction into undergraduate education through the perception and satisfaction of faculty and […]
Use of thermally treated manual NiTi instruments in teeth with severe curvatures: a case report

This case report aims to describe the endodontic treatment of a tooth with severe root dilaceration, using manually operated instruments made of heat-treated NiTi. A 14-year-old male patient, with a surgically treated cleft palate, was referred for endodontic treatment of the upper left lateral incisor (#22) for prosthetic reasons. Clinical examination revealed a crown formation […]
Evaluation of the cleaning efficacy of two nickel–titanium rotary systems: ProTaper Universal and heat-treated ProDesign S

Introduction: The purpose of endodontic instrumentation is to promote the cleaning and shaping of the root canal, preparing it for subsequent definitive obturation. Objective: The aim of this study was to evaluate, in vitro, the cleaning quality of simulated canal blocks instrumented by two nickel–titanium rotary systems. Methods: Twenty acrylic blocks (simulated canals) were used […]
The Use of Manual Nickel Titanium Files in the Optimization of the Treatment of Chronic Apical Periodontitis: A Case Report

The biomechanical preparation is a crucial step in endodontic treatment, responsible for shaping, cleaning, and disinfecting the root canals prior to obturation. However, performing this preparation ideally is always challenging, especially in complex anatomies where there is a risk of deviating from the original canal path. For years, this preparation was carried out using stainless […]
Pericervical Dentin Metrics in Mandibular First Molars Determined with Digital Periapical Radiography and Cone-beam Computed Tomography

Pericervical root dentin is decisive for the long-term mechanical integrity of root-filled teeth. Current treatment protocol does not include a customized step to determine the pretreatment residual pericervical root dentin.
Antibacterial ability of different activated irrigation after root canal preparation: intratubular analyses

This study assessed the intratubular antibacterial ability of different activated irrigations after chemical mechanical preparation. Seventy-two palatal root canals of upper molars were infected with Enterococcus faecalis for 4 weeks, and then initial bacterial collection from the main root canal was performed. The root canals were prepared by using a WaveOne Gold large (45/.05) and […]
