OBJECTIVES To investigate the prevalence of different primary reasons for endodontic referrals and the clinical symptoms of the referred cases. MATERIALS AND METHODS Clinical data of total endodontic treatment cases (1,014 teeth) including endodontic referral cases (224 teeth) between January 1, 2010 and December 31, 2012, at Kangdong Sacred Heart Hospital, were investigated retrospectively. ...

Cervicofacial subcutaneous emphysema is an infrequently reported sequela of dental surgery. It may be caused by the inadvertent introduction of air into the soft tissues during procedures using high-speed, air-driven handpieces or air-water syringes. In this paper, we present a case in which subcutaneous emphysema developed in a middle-aged woman following routine restorative treatment. We revi...

Conventional endodontic treatment used to require multiple visits, but some clinicians have suggested that single-visit treatment is superior. Single-visit endodontic treatment and multiple-visit endodontic treatment both have their advantages and disadvantages. This paper is a literature review of the research on nonsurgical single-visit versus multiple-visit endodontic treatment. The PubMed d...

OBJECTIVE The aims of this study were to investigate the presence of Enterococcus faecalis in primary endodontic infections and failed endodontic treatments using real-time PCR and to determine the statistical importance of the presence of E. faecalis in a Turkish population with endodontic infections. MATERIAL AND METHODS E. faecalis was investigated from 79 microbial samples collected from ...

On September 22, 2000, GYNECARE, a division of ETHICON, INC., undertook a voluntary global withdrawal of the GYNECARE VERSAPOINT Bipolar Electrosurgery System electrodes and handpieces in response to a small number of spontaneous reports of non-fatal air and gas embolism associated with use of the system during hysteroscopic myomectomy procedures.

A low-cost automated vitrectomy machine was developed locally by the Department of Medical Physics and Engineering at Edinburgh University. The machine uses disposable handpieces, and has proved to be user-friendly, reliable, and efficient for anterior segment vitrectomy and, for selected patients, for posterior segment vitrectomy. The construction and mechanics of the machine are described. Si...
