Accuracy of Cone-Beam Computed Tomography in Measuring the Thickness of Radicular Dentin.

The purpose of this study was to evaluate the accuracy of Cone-Beam Computed Tomography (CBCT) in measuring radicular dentin thickness focused on intraradicular post placement planning treatment. Ten single-rooted human premolars were selected. The teeth were divided into three segments (cervical, middle and apical).

Incidence of root resorption after concussion, subluxation, lateral luxation, intrusion, and extrusion: a systematic review.

Objective: Traumatic dental injuries often affect the dental hard tissues, periodontal tissues, and dental pulp. Root resorption (RR) is a significantly concerning phenomenon that could lead to loss of the traumatized tooth. The purpose of this systematic review was to analyze the incidences of different types of RR after concussion, subluxation, lateral luxation, intrusive luxation, and extrusive luxation.

Prevalence of radiographic findings on jaws exposed to antiresorptive therapy: a meta-analysis.

Objectives:: Determine the prevalence of radiographic findings (RF) on both jaws among patients receiving antiresorptive bone therapy.

Methods:: Six electronic databases and partial grey literature were searched. Data was collected based on predetermined criteria.

Prevalence of reported percutaneous injuries on dentists: A meta-analysis.

Objectives: To answer the focused question, "What are the prevalence of percutaneous injuries (PIs) on dentists, the location with the highest prevalence, and the dental instrument most responsible for these injuries?" As secondary outcomes, the prevalence by geographic location, type of PI, sex distribution, and dentist's specialty were also considered.

Eligibility Criteria: Observational descriptive studies investigating the prevalence of percutaneous injuries on dentists were included.

Sources: Five electronic databases and three partial grey literature searches were performed.

Incidence of Root Resorption after the Replantation of Avulsed Teeth: A Meta-analysis.

Introduction: An avulsion injury is a serious trauma to pulp and periodontal tissues. After avulsion and replantation, teeth are at risk of infection and root resorption, which may affect treatment outcome and survival rate. Thus, the purpose of this systematic review was to evaluate the incidence of root resorption after the replantation of avulsed teeth.

Impact of Evidence-Based Dentistry Workshops on Educators' Use of Evidence in Teaching and Practice: A Pilot Study.

The aims of this pilot study were to evaluate the short-term impact of evidence-based dentistry (EBD) workshops on educators' use of clinical evidence in their clinical practice and educational activities and to identify barriers they encountered in implementing evidence in their teaching and clinical practice. Between April 2012 and January 2014, a series of EBD workshops was delivered to 31 dental faculty members and postdoctoral students at three Canadian dental schools. Survey I, assessing participants' perceptions of various aspects of the workshops, was administered immediately following the workshops.

Prevalence of oral potentially malignant disorders: A systematic review and meta-analysis.

Oral potentially malignant disorders (OPMD) are chronic conditions, which have a higher risk of transformation to oral squamous cell carcinoma. The aim of this systematic review and meta-analysis was to answer the question: "What is the prevalence of oral potentially malignant disorders among adults?" Studies reporting the prevalence of these conditions (leukoplakia, erythroplakia, oral submucous fibrosis [OSMF], and actinic cheilitis) were selected, only studies in which a clinical assessment and histopathological confirmation were performed were included. Of the 5513 studies, 22 met the inclusion criteria for qualitative and quantitative analyses.

Incidence of reactive hyperplastic lesions in the oral cavity: a 10 year retrospective study in Santa Catarina, Brazil.

Introduction: Reactive hyperplastic lesions develop in response to a chronic injury simulating an exuberant tissue repair response. They represent some of the most common oral lesions including inflammatory fibrous hyperplasia, oral pyogenic granuloma, giant cell fibroma, peripheral ossifying fibroma, and peripheral giant cell lesions.

Objective: The incidence of those lesions was investigated in an oral pathology service, and the clinical characteristics, associated etiological factors, concordance between the clinical and histopathological diagnostic was determined.

Influence of Intracanal Materials in Vertical Root Fracture Pathway Detection with Cone-beam Computed Tomography.

Introduction: Investigating the vertical root fracture (VRF) pathway under different clinical scenarios may help to diagnose this condition properly. We aimed to determine the capability and intrareliability of VRF pathway detection through cone-beam computed tomographic (CBCT) imaging as well as analyze the influence of different intracanal and crown materials.

Methods: VRFs were mechanically induced in 30 teeth, and 4 clinical situations were reproduced in vitro: no filling, gutta-percha, post, and metal crown.

Diagnostic Accuracy of Cone-beam Computed Tomography and Conventional Radiography on Apical Periodontitis: A Systematic Review and Meta-analysis.

Introduction: Endodontic diagnosis depends on accurate radiographic examination. Assessment of the location and extent of apical periodontitis (AP) can influence treatment planning and subsequent treatment outcomes. Therefore, this systematic review and meta-analysis assessed the diagnostic accuracy of conventional radiography and cone-beam computed tomographic (CBCT) imaging on the discrimination of AP from no lesion.

Immunohistochemical expression of matrix metalloproteinases in ameloblastomas and pericoronal follicles.

Background: Ameloblastoma (AM) is a benign odontogenic neoplasm characterized by local invasiveness and recurrence. We compared the immunohistochemical expression of matrix metalloproteinases in different clinical types of AM as well as in normal odontogenic tissue.

Methods: Thirteen cases of solid AMs, five cases of unicystic AM and eight pericoronal follicles (PF) were selected and subjected to immunohistochemical investigation for matrix metalloproteinase-1, matrix metalloproteinase-2 and matrix metalloproteinase-9 expressions.
