The dilemma of juvenile fibrous dysplasia versus chronic osteomyelitis of the posterior mandible: A case report.

The clinical and radiographic dilemma of fibrous dysplasia versus osteomyelitis is highlighted in this case of a 4-year-old girl with a bony hard swelling in mandibular body and ramus. Rather than relying on histopathological appearance alone, dental professionals should be familiar with the radiographic differences between the two conditions.

Anterior buccal mandibular depression: A descriptive study of CT findings.

Objective: This study aims to report the concurrence of the radiographic features of anterior buccal mandibular depressions (ABMDs) and anterior lingual mandibular depressions (ALMDs) by conventional computed tomography (CT) and cone beam CT scans. We also assess the effect of ABMDs and ALMDs on dental implant sites.

Methods: A retrospective review of CT scans of the mandibles with ABMDs was conducted to assess the morphology, site, presence of foramina, ALMDs, and the integrity of the cortical plate.

Sialolipoma of the Floor of the Mouth with Immunohistological Analysis.

Lipomas are relatively rare in the head and neck, and sialolipoma was described as an entity about 20 years ago as lipoma that entraps salivary gland tissue. Less than 10 cases have been described in the floor of the mouth not related to the major salivary glands. Here, we report a case of sialolipoma affecting the floor of the mouth in a 47-year-old patient and reviewed the clinical, histologic, and immunohistochemical characteristics of the lesion.

Bilateral Anterior Lingual Depression in the Mandible: Cone Beam Computed Tomography Case Report and Review of the Literature.

The mandibular anterior lingual depression is an uncommon anatomical variant. It is difficult to be detected in conventional 2D plain radiographs representing a diagnostic challenge. In this report, we describe a patient who presented to the dental clinic for the extraction of impacted third molars.

Effect of ultra-low doses, ASIR and MBIR on density and noise levels of MDCT images of dental implant sites.

Objectives: Differences in noise and density values in MDCT images obtained using ultra-low doses with FBP, ASIR, and MBIR may possibly affect implant site density analysis. The aim of this study was to compare density and noise measurements recorded from dental implant sites using ultra-low doses combined with FBP, ASIR, and MBIR.

Methods: Cadavers were scanned using a standard protocol and four low-dose protocols.

Validity of linear measurements of the jaws using ultralow-dose MDCT and the iterative techniques of ASIR and MBIR.

Purpose: To assess the comparability of linear measurements of dental implant sites recorded from multidetector computed tomography (MDCT) images obtained using standard-dose filtered backprojection (FBP) technique with those from various ultralow doses combined with FBP, adaptive statistical iterative reconstruction (ASIR), and model-based iterative reconstruction (MBIR) techniques. The results of the study may contribute to MDCT dose optimization for dental implant site imaging.

Methods: MDCT scans of two cadavers were acquired using a standard reference protocol and four ultralow-dose test protocols (TP).

A One-Day Dental Faculty Workshop in Writing Multiple-Choice Questions: An Impact Evaluation.

Long training workshops on the writing of exam questions have been shown to be effective; however, the effectiveness of short workshops needs to be demonstrated. The aim of this study was to evaluate the impact of a one-day, seven-hour faculty development workshop at the College of Dentistry, King Saud University, Saudi Arabia, on the quality of multiple-choice questions (MCQs). Kirkpatrick's four-level evaluation model was used.

Epithelioid Osteosarcoma of the Maxilla: A Case Report and Review of the Literature.

Epithelioid osteosarcoma is an uncommon variant; only 4 cases have been reported in the jaw area, 2 of which were in the maxilla. A 22-year-old woman, in the eighth month of pregnancy, presented to the oral surgery clinic with a mass in the right maxilla that had rapidly expanded over the past 3 months. Computed tomography scans showed an ill-defined sclerotic destructive lesion that formed bone matrix in its soft tissue extension.

The validity of different display monitors in the assessment of dental implant site dimensions in cone beam computed tomography images.

Objective: To determine if the differing contrast resolution of various LCD monitors affects the reliability or accuracy of measurements of proposed implant sites.

Materials And Methods: Edentulous areas of human dry skulls were marked with radiopaque markers in order to standardize the plane of the transverse cross-sections of the ridges and path of measurements. The skulls were imaged by a CBCT device and the images stored in proprietary format on the workstation.

Prevalence of carotid calcification detected on panoramic radiographs in a Saudi population from a training institute in Central Saudi Arabia.

Objective: To determine the prevalence of carotid artery calcification as detected on panoramic radiographs in a Saudi population.

Methods: This cross sectional study was conducted at the College of Dentistry, King Saud University, Saudi Arabia between March 2008 and January 2009. Five hundred and fifty-five panoramic radiographs of Saudi patients aged 30 years and above was collected from the patient charts.

Postgraduate specialties interest, career choices and qualifications earned by male dentists graduated from King Saud University.

Objectives: To study the career development of male graduates of King Saud University (KSU), College of Dentistry in terms of pursuit of postgraduate dental education, higher degrees or Board Certification, choice of universities and countries of study, and place of work after qualification.

Methods: A questionnaire survey was carried out through face to face or telephone interview among 666 KSU graduates of 1982-2004.

Results: 80% (532 graduates) response rate.
