Background: To determine the agreement rate between histopathologic diagnosis and radiographic interpretation of jaw lesions.

Methods: Cases with jaw pathologies that have diagnostically adequate histopathologic samples and radiographic examinations were reviewed retrospectively. Two board-certified oral and maxillofacial pathologists (OMFP) independently determined the histopathologic diagnosis, while two board-certified oral and maxillofacial radiologists (OMFR) determined the radiographic interpretations independently.

The effect of varying cone beam computed tomography image resolution and field-of-view centralization on effective radiation dose.

To investigate changes in the effective radiation dose (E) in relation to variations in voxel (VOX) size settings and the field-of-view (FOV) centralization. Methods: This cross-sectional dosimetry study used nanoDot OSLD dosimeters placed at 25 pre-determined sites in the head and neck slices of a RANDO male phantom to measure the absorbed radiation. The imaging scans took place at King Abdulaziz University Dental Hospital, Jeddah, Saudi Arabia between September 2016 and May 2017 using the i-CAT classic cone beam computed tomography (CBCT)  unit.

Quantitative assessment of mandibular canal compression assessed by cone beam computed tomography.

Objective: The aim of this study was to objectively quantify the topographic relation of the mandibular canals, impacted third molars, and cortical plates using cone beam computed tomography (CBCT).

Study Design: A retrospective chart review was conducted using the database of a university-based imaging service. Two calibrated reviewers examined the CBCT images of 100 cases scheduled for mandibular third molar removal.

Osteoma Cutis of the Face in CBCT Images.

Osteoma cutis (OC) is a rare benign disorder where osseous nodules form in the reticular layer of normal skin. These nodules are formed by the deposition of lamellar bone and are characterized by osteocytes in the core and osteoclasts around the periphery. Interpretation of osteoma cutis cases has always been challenging especially using conventional two-dimensional (2D) radiographs, owing to difficulty in localization.

Age, gender and parafunctional habits as prognostic factors for temporomandibular joint arthrocentesis.

Objective: Arthrocentesis is an effective procedure for management of symptomatic patients with temporomandibular joint (TMJ) anterior disc displacement without reduction (ADDWOR), but its prognostic factors are still under investigation.

Methods: Thirty-six patients with ADDWOR underwent arthrocentesis of the TMJ and hyaluronic acid injection. They were divided into groups based on three prognostic factors: Age, gender, and the presence of parafunctional habits.

Single file reciprocating systems: A systematic review and meta-analysis of the literature: Comparison of reciproc and WaveOne.

The introduction of single-file nickel-titanium (NiTi) reciprocating systems has been a major breakthrough in the field of endodontics. Thus, the aim of this study was to compare the available reciprocating systems, Reciproc and WaveOne, using a meta-analysis with different parameters. A comprehensive electronic literature search for Reciproc and WaveOne using PubMed and Google scholar was initially conducted in September 2014 and updated in September 2016.
