Purpose: The aim of the present study was to use cone-beam computed tomography (CBCT) images of patients to assess the localization, diameter, and course of the lateral lingual vascular canal (LLVC).

Methods: CBCT (Morita, Accuitomo 170) images from 500 patients were used in the present study. The CBCT images were examined by two oral radiologists.

Effect of chewing on dental patients with total denture: an experimental study.

In this study, we have explored the prospect of assessing and following level of total denture adaptation by use of EMG signals recorded during gum chewing. Total of 14 edentulous patients, 6 women and 8 men, with an average age of 63±9 years, were recruited. Separate EMG recordings were obtained from left and right temporalis and masseter muscles of the patients for a period of 10 seconds, while they were chewing a sugar-free gum on their left and right sides.

A patient with Eagle syndrome: radiological and scintigraphic evaluation.

A 42-year-old man who had been having otalgia and facial and neck pain for 6 months presented for a routine dental examination. He had suffered two head traumas, the first 20 years ago and the second 4 years ago. A panoramic radiograph (PR) was taken as a screening film after the clinical examination.

Infantile malignant osteopetrosis: report of 2 cases with osteomyelitis of the jaws.

Infantile malignant osteopetrosis (IMO) is an uncommon autosomal recessive disease characterized by dense, brittle, sclerotic, radiopaque bones, which generally results in neurological and hematological abnormalities. In general, IMO is fatal, as patients fail to grow and expire due to complications of the disease such as severe chronic anemia, bleeding, and/or infections. In children with IMO, the development of the dentition is seriously disturbed.

Clinical and radiographic evaluation and comparison of six cases of fusion involving the primary dentition.

Fusion occurs infrequently, but could cause esthetic, spacing, and periodontal problems. An understanding of fused teeth and their associated problems is important to provide prophylactic measures, thereby preventing or minimizing possible complications. The purpose of this case report was to highlight the infrequency of fused primary teeth by virtue of the number of such cases reported in the literature.

Prevalence of bifid mandibular condyle in a Turkish population.

The aim of this study was to determine the frequency of bifid mandibular condyle (BMC) using panoramic radiographs supported by different radiographic techniques. A retrospective study was carried out by evaluating panoramic radiographs of 18,798 patients referred to the Department of Dentomaxillofacial Radiology. T-tests were used to compare the frequency of BMC between left and right sides and between female and male patients.

Objective: This study aimed to determine the diagnostic reliability of panoramic radiographs (PRs) in the detection of carotid artery calcifications (CACs) during routine dental examination by comparing them with color Doppler ultrasound (CDUS) examination as the criterion standard. The correlations between CAC formation and systemic diseases, body mass index, smoking, and age were also examined.

Study Design: A total of 70 patients >40 years old diagnosed with CACs from PRs obtained during routine dental examination between January 2008 and September 2009 and 35 patients with no CACs (control group) were referred for further ultrasound examination.
