The purpose of this pilot study was to evaluate whether periapical granulomas can be differentiated from periapical cysts in vivo by using dental magnetic resonance imaging (MRI). Prior to apicoectomy, 11 patients with radiographically confirmed periapical lesions underwent dental MRI, including fat-saturated T2-weighted (T2wFS) images, non-contrast-enhanced T1-weighted images with and without fat saturation (T1w/T1wFS), and contrast-enhanced fat-saturated T1-weighted (T1wFS+C) images. Two independent observers performed structured image analysis of MRI datasets twice...

OBJECTIVE: Parathyroid hormone (PTH) enhances bone healing. Strontium ranelate (SR) is an antiresorptive agent that increases bone formation. Reports about combined effects of PTH and SR on local bone regeneration in osteoporotic subjects are limited. We aimed at investigating the efficacy of PTH and SR for promoting new bone formation in critical sized defects of ovariectomized rats. MATERIALS AND METHODS: PTH- and/or SR-containing poloxamer implant tablets with/without chitosan microparticles were delivered locally to calvarial defects of 90 Wistar rats...

Background: Severe early childhood caries (S-ECC) is common and has adverse affects on children's health. Children with S-ECC have been shown to have anemia or vitamin D deficiency. No studies have assessed the presence of combined deficiencies with S-ECC. The purpose of our study was to examine whether those with S-ECC had a higher prevalence of combined anemia and low 25-hydroxyvitamin D (25(OH)D) compared to controls. Covariates associated with elevated parathyroid hormone (PTH), previously noted in S-ECC, were examined...

This study aims to identify and distinguish various factors that may influence the clinical symptoms (limited mouth opening and malocclusion) in patients with maxillofacial fractures. From January 2000 to December 2009, 963 patients with maxillofacial fractures were enrolled in this statistical study to aid in evaluating the association between various risk factors and clinical symptoms. Patients with fractured posterior mandibles tended to experience serious limitation in mouth opening. Patients who sustained coronoid fractures have the highest risk of serious limitation in mouth opening (OR = 9...

BACKGROUND: In implant dentistry, three-dimensional (3D) imaging can be realised by dental cone beam computed tomography (CBCT), offering volumetric data on jaw bones and teeth with relatively low radiation doses and costs. The latter may explain why the market has been steadily growing since the first dental CBCT system appeared two decades ago. More than 85 different CBCT devices are currently available and this exponential growth has created a gap between scientific evidence and existing CBCT machines...

Fear of treatment by an oral and maxillofacial (OMF) surgeon or the dentist is a widespread and deep-rooted phenomenon. A patient can be taught to cope with dental phobia by means of psychological, cognitive behavioural therapy, but in cases of invasive oral treatment, such therapy may be insufficiently effective. For these invasive procedures, sedation serves as an alternative treatment option. The department of Oral and Maxillofacial Surgery at the Radboud University Medical Centre in Nijmegen, the Netherlands, offers the possibility to utilise intravenous sedation with midazolam (Dormicum®) and remifentanil (Ultiva®)...

Third molar extraction is a common procedure in dental surgery. Common complications that may occur post procedure include pain, trismus, bleeding, dry socket, and nerve injuries. Subcutaneous emphysema is an uncommon complication. A rare case of extensive cervicofacial subcutaneous emphysema, pneumomediastinum, and pneumorrhachis following third molar extraction is reported here. Issues relating to the diagnosis, aetiology, and management of these complications are discussed.

Hong Kong, as a special administrative region of the People’s Republic of China, is a metropolitan city in Asia with a population of approximately 7.4 million. This paper reflects the oral health care situation in Hong Kong. Water fluoridation was introduced in 1961 as the primary strategy for the prevention of dental caries. The fluoride level is currently 0.5 parts per million. Dental care is mainly provided by private dentists. The government’s dentists primarily serve civil servants and their dependents, with limited emergency dental service for pain relief offered to the general public...

Brain abscess (BA) is an encapsulated infection and can be the consequence of head and cranio-maxillo-facial surgery or trauma, or may be secondary to cavernous thrombophlebitis, but is most frequently due to hematogenous septic dissemination from an adjacent site of infection, such as the paranasal sinuses, middle ear or oral cavity. We report a rare and unfortunate case of multiple BA caused by dental procedures in a young man with undiagnosed patent foramen ovale (PFO). Simple routine dental procedures, such as tooth brushing and professional oral hygiene, can predispose to life-threatening conditions...

REVIEW
Anders Palmquist
Osseointegrated implants are frequently used in reconstructive surgery, both in the dental and orthopedic field, restoring physical function and improving the quality of life for the patients. The bone anchorage is typically evaluated at micrometer resolution, while bone tissue is a dynamic composite material composed of nanoscale collagen fibrils and apatite crystals, with defined hierarchical levels at different length scales. In order to understand the bone formation and the ultrastructure of the interfacial tissue, analytical strategies needs to be implemented enabling multiscale and multimodal analyses of the intact interface...
