Idiopathic Osteosclerosis and Condensing Osteitis in a Sample of the Lebanese Population: A Digital Panoramic Based Study.

Background: Idiopathic osteosclerosis (IO) is an area of enlarged bone production in the jaw that usually appears radiopaque and round, elliptical, or irregular in shape. Condensing osteitis (CO) is a focalized osseous reaction leading to periapical sclerotic bone growth.

Objective: The aim of this study was to investigate the prevalence, localization, shape, and dental relationship of IO and CO in a group of Lebanese patients and to correlate these findings to age and gender.

Bone Apposition in the Mandibular Angle in Adult Patients Diagnosed with Bruxism: a Digital Panoramic Based Study.

Background: Bruxism is defined as a movement disorder of the masticatory system leading to serious problem in the integrity of the oral dentition; it is characterized by teeth grinding and clenching and has been typically classified into three types: a) bruxism occurring during sleep, b) awake-related bruxism, and c) mixed sleep/awake-related bruxism.

Objective: The aim of this study was to assess any bone apposition in the mandibular angle in a group of adult patients diagnosed with bruxism using digital panoramic radiographs.

Methods: In the sample of 150 digital panoramic radiographs of 66 women and 84 men with an age range of 24-78 years and diagnosed with bruxism were evaluated.

Image-based Bone Density Classification Using Fractal Dimensions and Histological Analysis of Implant Recipient Site.

Background: Success of dental implants is affected by the quality and density of the alveolar bone. These parameters are essential for implant stability and influence its load-bearing capacity. Their assessment is usually based on preoperative radiographs used as a tool prior to implant procedures.

Mapping Maxillary Sinus Septa in a Lebanese Sample: a Radio-anatomical Study.

Introduction: Sinus septa are bony processes that develop in a variable fashion. Such structures present a challenge for surgical procedures of the maxillary sinuses.

Aim: This study aims to evaluate the prevalence and patterns of maxillary sinus septa in a sample from the Lebanese population.

Mandibular Metastasis of a Recurrent Poorly Differentiated Urothelial Bladder Carcinoma.

Metastatic lesions to the oral cavity are uncommon; they represent between 1 and 3% of all malignant oral neoplasms. In this article, we report a rare case of metastatic urothelial bladder carcinoma in the mandible detected on oral radiographic images and confirmed with multiple imaging modalities. A 67-year-old woman presented to our clinic suffering from pain in the right side of the mandible with a mild swelling.

Correlating Radiographic Fractal Analysis at Implant Recipient Sites with Primary Implant Stability: An In Vivo Preliminary Study.

Objectives The aim of this study was to demonstrate a possible correlation between radiographic trabecular bone quantified with fractal dimensions analysis and values of primary implant stability deliberated using the Osstell monitor (Integration Diagnostics AB, Goteborgsvagen, Sweden) with the density of bone specimens harvested from the implant recipient sites and calculated using the mass and volume of the bone bloc specimens. Material and methods Fifty implants of the same brand, diameter, and length were inserted with the same surgical procedures; 25 implants in the molar premolar region of the maxilla and 25 implants in the mandibular posterior region of only healthy male patients between 20 and 50 years of age. Prior to the placement of the implants, biopsies were taken from the selected site for density calculation using a calibrated trephine.

Location of Posterosuperior Alveolar Artery and Correlation with Maxillary Sinus Anatomy.

The blood supply to both the lateral wall of the maxillary sinus and the overlying membrane originates from the posterosuperior alveolar artery (PSAA) and the infraorbital artery. The purpose of the present study was to evaluate the anatomic characteristics of the PSAA in a large number of subjects of the Lebanese population. Images of 696 sinuses were analyzed using cone beam computed tomography (CT).

Number of basis images effect on detection of root fractures in endodontically treated teeth using a cone beam computed tomography machine: an in vitro study.

Objectives: The objective of this study was to compare the accuracy of root fracture detection in endodontically treated teeth using scans acquired with a 180° rotation motion compared with a 360° after which the patient exposure and number of basis images are doubled.

Methods: Sixty-six roots were collected and decoronated. All were treated endodontically.
