Impact of Type 2 Diabetes Mellitus on the Occurrence of Vertical Root Fracture: A Case Control Study.

Introduction: The aim of this case-control study was to examine the relationship between type 2 diabetes mellitus (DM) and the occurrence of VRFs. The crack extension, dentin sclerosis, and chemical characteristics of root dentin in teeth with VRF from patients with/without DM were also compared.

Methods: One hundred and thirty-two patients diagnosed with VRF in crowned root filled posterior teeth were selected.

Clinical Outcome of Nonsurgical Root Canal Treatment Using a Matched Single-Cone Obturation Technique with a Calcium Hydroxide-based Sealer: A Retrospective Analysis.

Introduction: The aim of this retrospective study was to estimate the outcome of nonsurgical root canal treatment using matched single-cones with a calcium hydroxide-based sealer and to identify the various prognostic factors influencing the outcome.

Methods: This was a retrospective study that enrolled 272 patients who underwent routine endodontic therapy and were obturated with matched single-cones and Sealapex as sealer. This study involved 223 patients with 261 teeth meeting the selection criteria and recalled between 24 and 84 months.

A Cone Beam Computed Tomography of the Root Canal Morphology of Maxillary Anterior Teeth in an Institutional-Based Study in Chennai Urban Population: An Study.

Aim: This study aims to investigate the root canal anatomy of human extracted permanent maxillary anterior teeth in patients reporting to our dental institution in Chennai using cone beam computed tomography (CBCT).

Materials And Methods: A total of 285 maxillary anterior teeth comprising of 100 central incisors, 85 lateral incisors, and 100 canines extracted from various patients reporting to our institution were studied. The number of roots and number of canals were assessed; following which, the root canal anatomy of each tooth was evaluated for the canal pattern using CBCT.

Diagnosis of Vertical Root Fractures in Restored Endodontically Treated Teeth: A Time-dependent Retrospective Cohort Study.

Introduction: The purpose of this study was to examine different patient- and treatment-related factors associated with the time of presentation of vertical root fractures (VRFs) in endodontically treated teeth restored with crowns.

Methods: One hundred ninety-seven root-filled, crowned teeth with no post and suspected of VRFs were included in the study. Patient details with relevance to endodontic treatment and clinical signs/symptoms were documented, and radiographs were taken.

Comparative evaluation of canal isthmus debridement efficacy of modified EndoVac technique with different irrigation systems.

Introduction: The purpose of this study was to evaluate the canal isthmus debridement efficacy of a new modified EndoVac (Discus Dental, Culver City, CA) irrigation protocol in comparison with EndoVac, passive ultrasonic irrigation (PUI), and conventional needle irrigation in mesial roots of mandibular molars.

Methods: The mesial roots of 64 extracted mandibular molars mounted in resin using Kuttler's endodontic cube, sectioned at 2 and 4 mm from the working length, were randomly divided into 4 groups (n = 16): group 1: Max-I-Probe (Dentsply Tulsa Dental, York, PA), group 2: EndoVac (EVI), group 3: modified EndoVac, and group 4: PUI. The specimens were reassembled and instrumented.
