An In Vivo and Cone Beam Computed Tomography Investigation of the Accuracy in Measuring Alveolar Bone Height and Detecting Dehiscence and Fenestration Defects.

Purpose: To investigate cone beam computed tomography (CBCT) accuracy in measuring facial bone height and detecting dehiscence and fenestration defects around teeth.

Materials And Methods: Patients who were treatment planned for periodontal flap or dental implant surgeries were enrolled (n = 25). CBCT imaging (Carestream CS 9300) was obtained at 0.

Using Twitter for Teaching and Learning in an Oral and Maxillofacial Radiology Course.

The aim of this study was to describe the implementation of one form of social media (Twitter) in an oral radiology course and evaluate dental students' use and perceptions of this technology for teaching and learning. An author-developed questionnaire was used to solicit second-year students' knowledge, use, and perceptions of Twitter for teaching and learning in an oral radiology course at one U.S.

Alveolar bone loss is associated with circulating anti-citrullinated protein antibody (ACPA) in patients with rheumatoid arthritis.

Background: This study examines: 1) alveolar bone loss (ABL), a hallmark of periodontitis, in anti-citrullinated protein antibody (ACPA)-positive rheumatoid arthritis (RA) patients versus control patients with osteoarthritis (OA); and 2) the association of ABL with RA disease activity and ACPA concentrations, including multiple antigen-specific ACPA.

Methods: This multicenter case-control study includes 617 patients diagnosed with RA (n = 287) or OA (n = 330). Panoramic radiographs were taken; patients were categorized into low, moderate, or high tertiles based on mean percentage ABL.

Periodontitis and Porphyromonas gingivalis in patients with rheumatoid arthritis.

Objective: To examine the degree to which shared risk factors explain the relationship of periodontitis (PD) to rheumatoid arthritis (RA) and to determine the associations of PD and Porphyromonas gingivalis with pathologic and clinical features of RA.

Methods: Patients with RA (n = 287) and patients with osteoarthritis as disease controls (n = 330) underwent a standardized periodontal examination. The HLA-DRB1 status of all participants was imputed using single-nucleotide polymorphisms from the extended major histocompatibility complex.

A dentigerous cyst associated with bilaterally impacted mandibular canines in a girl: a case report.

Introduction: A dentigerous cyst is the most common developmental odontogenic cyst and is frequently noted as an incidental finding on radiographs. The most common teeth affected are impacted mandibular third molars and permanent maxillary canines. This case involves a dentigerous cyst encompassing the right and left impacted mandibular canines and crossing the midline.
