Diffusion weighted (DW) MRI facilitates non-invasive quantification of tissue microstructure and, in combination with appropriate signal processing, three-dimensional estimates of fibrous orientation. In recent years, attention has shifted from the diffusion tensor model, which assumes a unimodal Gaussian diffusion displacement profile to recover fibre(More)
PURPOSE To prospectively investigate the efficacy of a wire basket extractor in the retrieval of salivary calculi and establish selection criteria for suitable cases. MATERIALS AND METHODS Twenty-five consecutive patients (14 male, 11 female; age range, 13-69 years) with salivary calculi (20 submandibular, five parotid) were treated by using a(More)
Perforation of the lower third molar roots by the inferior alveolar nerve is uncommon and can be difficult to determine by conventional radiographic methods. Presented is a case of perforation that was treated by coronectomy, and showed an unusual complication in that the retained root erupted, moving the canal with it. The radiographic assessment of root(More)
Purpose: To describe the technique and examine the value of salivary stone extraction using a minimally invasive, radiologically guided approach as an alternative to salivary gland surgery for the treatment of benign salivary gland obstruction. Methods: Eighty-six cases of sialolithiasis (83 patients) were treated by stone removal using a Dormia basket(More)
Purpose: This paper describes the technique for balloon dilatation of salivary duct strictures and evaluates the clinical and radiographic findings in a consecutive series of 36 affected glands. Methods: Thirty-four patients (36 glands) had balloon dilatation of their salivary duct strictures performed under fluoroscopic control. They were evaluated(More)
OBJECTIVES The aim of this study was to establish the incidence and character of salivary duct strictures by carrying out a 10 year retrospective review. Salivary gland obstruction is most commonly caused either by salivary calculi or duct strictures. These strictures or stenoses develop secondarily to inflammation in the duct wall and may be single or(More)
AIM To compare the accuracy of digital radiography (DR), multidetector computed tomography (MDCT) and cone beam computed tomography (CBCT) in detecting vertical root fractures (VRF) in the absence and presence of gutta-percha root filling. METHODOLOGY The root canals of 100 extracted human single-rooted teeth were prepared and randomly divided into four(More)
We studied 43 patients (25 women and 18 men) who had salivary calculi removed from the hilum of the submandibular gland. Preoperatively they had clinical and radiographic examinations, and glandular function was measured scintigraphically in 38 patients. Postoperative follow-up was based on history, clinical examination, structured questionnaire, and(More)
OBJECTIVES The aim was to investigate the relationship between bone mineral density (BMD) of the jaws (mandible and maxilla) and other skeletal sites. In addition, the influence of gender, smoking and the number of years without natural teeth were examined. MATERIALS AND METHODS 18 edentulous patients (9 females, 9 males) with a mean age of 67.1 (sd 12.6)(More)
We present a case of haemangioma of the mandible in a 46-year-old woman. The radiological appearance was of a unilocular radiolucency that looked similar to other more common lesions of the mandible. This case shows that a potentially life-threatening haemangioma can present as an apparently benign cyst-like unilocular radiolucency, and highlights the need(More)
