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)
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)
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)
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 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)
Maxillary canines are the second most common teeth to become impacted, following third molars. Variable levels of incidence have been reported but roughly fall between 1-2.5%. The aetiology of impaction is unknown but both environmental and genetic factors have been suggested. The majority of impacted canines are palatally displaced and such ectopic teeth(More)
BACKGROUND The aim was to investigate the results of extracorporeal shockwave lithotripsy in the management of salivary calculi using a dedicated sialolithotriptor. METHODS Some 122 salivary calculi (84 submandibular and 38 parotid) were treated in an experimental study using a sialolithotriptor. RESULTS Complete success was achieved in 40 procedures(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)
The limitations of plain film radiographs are well documented and the recent introduction of cone beam computed tomography (CBCT) imaging has been a breakthrough in enabling three-dimensional (3D) visualization of the bony skeleton and dentition. There are many reported applications for CBCT in the field of orthodontics and maxillofacial surgery, including(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)
