Buccal plate thickness as a predictor for endodontic microsurgery outcomes: A retrospective cohort study.

Objective: The aim of the study was to determine the relationship between preoperative buccal plate thickness (BPT) and radiographic healing at the osteotomy site after endodontic microsurgery (EMS) with and without guided tissue regeneration (GTR) using cone beam computed tomography (CBCT) imaging.

Study Design: The retrospective sample of 143 individuals who had EMS with pre- and postoperative CBCT scans available were divided into 2 groups: group 1 (GTR) and group 2 (no GTR), which were further divided into teeth where BPT was >1.0 mm or ≤1.

Comparison of endodontic diagnosis and treatment planning decisions using cone-beam volumetric tomography versus periapical radiography.

Introduction: Accurate and confident treatment planning is an essential part of endodontic practice. Periapical radiographs have been used to aid in the diagnosis of pathology and to help establish an appropriate treatment strategy. Recently, a new imaging modality, cone-beam volumetric tomographic (CBVT) imaging, has been shown to be a useful tool in a number of endodontic applications.

Different representations of vertical root fractures detected by cone-beam volumetric tomography: a case series report.

Introduction: Vertical root fractures (VRFs) pose a clinical dilemma and a challenge to clinicians. Definitive diagnosis is often complicated by the lack of consistent signs and symptoms and the low sensitivity of conventional radiographs in the detection of VRFs. New radiographic imaging systems have recently become available for use in dentistry.

Efficacy of berberine, an antimicrobial plant alkaloid, as an endodontic irrigant against a mixed-culture biofilm in an in vitro tooth model.

Introduction: Berberine, a plant alkaloid isolated from many medicinal plants, has shown antimicrobial activity against selected oral pathogens. The purpose of this investigation was to evaluate the antimicrobial efficacy of berberine solution against selected endodontic pathogens using a multispecies biofilm tooth model.

Methods: The bacterial species used in the multispecies biofilm tooth model were Fusobacterium nucleatum, Enterococcus faecalis, and Prevotella intermedia.

Biomimetic approach to perforation repair using dental pulp stem cells and dentin matrix protein 1.

Introduction: Dentin regeneration could be an ideal treatment option to restore tissue function. This study was conducted to evaluate the ability of dental pulp stem cells (DPSCs) and dentin matrix protein 1 (DMP1) impregnated within a collagen scaffold to regenerate dentin.

Methods: Simulated perforations were created in 18 dentin wafers made from freshly extracted human molars.

Biologic markers for odontogenic periradicular periodontitis.

Introduction: The diagnosis and assessment of apical periodontitis by traditional periapical radiographs can be challenging and might yield false-negative results. The aim of this study was to determine whether interleukin-1beta (IL-1beta) and dentin sialoprotein (DSP) in gingival crevicular fluid (GCF) can be used as biological markers for apical periodontitis.

Methods: Forty healthy patients with teeth diagnosed with apical periodontitis of pulpal origin were included in the study.

In vivo generation of dental pulp-like tissue by using dental pulp stem cells, a collagen scaffold, and dentin matrix protein 1 after subcutaneous transplantation in mice.

The presence of a perforation is known to significantly compromise the outcome of endodontic treatment. One potential use of regenerative endodontic therapy might be the repair of root canal perforations. In addition to nutrients and systemic in situ interactions, the 3 main components believed to be essential for tissue regeneration are stem cells, scaffold, and growth factors.

Outcome of one-visit and two-visit endodontic treatment of necrotic teeth with apical periodontitis: a randomized controlled trial with one-year evaluation.

The choice of one-visit versus two-visit root canal therapy for necrotic teeth with apical periodontitis is a source of current debate. The primary objective of this randomized controlled clinical trial was to compare radiographic evidence of periapical healing after root canal therapy completed in one visit or two visits with an interim calcium hydroxide/chlorhexidine paste dressing. Ninety-seven patients met the inclusion criteria and consented to participate in this study.

Antimicrobial effect of triclosan and triclosan with Gantrez on five common endodontic pathogens.

Microbial control of the root canal system is one of the key objectives of root canal therapy. Triclosan is a widely accepted broad spectrum antimicrobial agent proven to be effective against many gram-positive and gram-negative bacteria. Triclosan acts by blocking bacterial fatty acid biosynthesis.

Application and assessment of a dipstick assay in the diagnosis of hydatidosis and trichinosis.

The aim of the present work was to apply and evaluate a dipstick assay for the serodiagnosis of human hydatidosis as well as human and experimental trichinosis using camel hydatid cyst fluid (HCF) and Trichinella spiralis muscle larval (TSML) antigens, respectively, and compare this to enzyme-linked immunoelectrotransfer blot (EITB) and Falcon assay screening test-enzyme-linked immunosorbent assay (FAST-ELISA). Sera samples were collected from patients with confirmed hydatidosis and trichinosis and with other parasitic diseases as well as from normal healthy individuals. Also, sera samples were collected from mice experimentally infected with T.

The effect of CO2 laser irradiation on PDL cell attachment to resected root surfaces.

Objectives: The effect of CO2 laser irradiation on PDL attachment to resected root ends was evaluated.

Study Design: Forty dentin wafers were divided into 4 equal groups. Groups I and II were not subjected to laser irradiation.

Evaluation of canal cleanliness and smear layer removal after the use of the Quantec-E irrigation system and syringe: a comparative scanning electron microscope study.

Objective: The purpose of this study was to evaluate canal cleanliness and smear layer removal after use of the Quantec-E irrigation system and to compare the system with traditional irrigation.

Study Design: Forty anterior teeth were randomly assigned to 4 groups. Group A consisted of 15 teeth that were instrumented with .
