The public perception of the differences between specialist orthodontists and general dentists: A comparison between Australia and Sweden.

Introduction: In Australia and Sweden, orthodontic treatments may be performed by either a general dental practitioner (GDP) or a specialist orthodontist. Evidence suggests that the public may easily confuse a GDP who provides orthodontic treatment with a specialist orthodontist. We conducted a survey of people in Australia and Sweden to assess their understanding of the differences between a specialist orthodontist and a GDP who provides orthodontic treatments.

Satisfactory outcomes after orthognathic surgery with surgically assisted rapid maxillary expansion using a hybrid device.

The self-reported functional outcomes, clinical findings, and results of dental cast analysis before and after orthognathic surgery with surgically assisted rapid maxillary expansion (SARME) using a hybrid rapid maxillary expander (RME) were evaluated. Data were collected from 43 patients who underwent orthognathic surgery with SARME using a hybrid RME between 2001 and 2013. The patients were recruited during a follow-up clinical examination and were required to complete a questionnaire about their opinions and self-reported functional outcomes.

Treatment of adolescent patients with class II division 1 malocclusion using Eruption guidance appliance: A comparative study with Twin-block and Activator-Headgear appliances.

The aim of this study was to evaluate the compliance and short-term effects of eruption guidance appliance (EGA) in adolescents with class II division 1 malocclusion in comparison with twin-block appliance (TBA) and activator-headgear appliance (A-HG). Dental records of 1886 patients were viewed in this retrospective study 129 patients treated with one of these three functional appliances were identified. 123 fulfilled the inclusion criteria and data were extracted from the dental records.

Expression of prostaglandin E synthases in periodontitis immunolocalization and cellular regulation.

The inflammatory mediator prostaglandin E(2) (PGE(2)) is implicated in the pathogenesis of chronic inflammatory diseases including periodontitis; it is synthesized by cyclooxygenases (COX) and the prostaglandin E synthases mPGES-1, mPGES-2, and cPGES. The distribution of PGES in gingival tissue of patients with periodontitis and the contribution of these enzymes to inflammation-induced PGE(2) synthesis in different cell types was investigated. In gingival biopsies, positive staining for PGES was observed in fibroblasts and endothelial, smooth muscle, epithelial, and immune cells.
