STATEMENT OF PROBLEM Screw loosening has been a common complication and still reported frequently. PURPOSE The purpose of this study was to evaluate abrasion of the implant fixture and TiN coated abutment screw after repeated delivery and removal with universal measuring microscope. MATERIAL AND METHODS Implant systems used for this study were Osstem and 3i. Seven pairs of implant fixtures,...

OBJECTIVES Published experiences with thoracoscopic apical or total pleurectomy for patients with a pneumothorax are limited. We aimed to evaluate the long-term results and effectiveness of pleurectomy in our patients, that vast majority of whom underwent thoracoscopic apical or total pleurectomy. MATERIAL AND METHODS Between January 2001 and December 2010, in the Istanbul University Medical ...

Objective: A cross-sectional study was carried out to assess standard precaution practices among dental personnel and to investigate microbial counts in indoor air samples collected from a hospital dental clinic before and during dental works. Material and Method: Thirty dental personnel who voluntarily participated were interviewed using a questionnaire towards demographic information and stan...

PURPOSE We investigated surgical results of staple line coverage with a polyglycolic acid sheet plus pleural abrasion by thoracoscopic surgery for treating primary spontaneous pneumothorax in young patients. METHODS Forty-seven patients younger than 40 years underwent 48 thoracoscopic surgical procedures for spontaneous pneumothorax at the Division of Thoracic Surgery, Department of Surgery, ...

The heat treatment of dental alloys prior to porcelain application/veneering has been proposed as a way ensure sufficient oxide scale and promote the porcelain’s adherence in porcelain-fused-to-metal (PFM) fixed prostheses. present study investigates relationship between bond strength selective-laser-melted (SLM) titanium temperature titanium’s pre-oxidation. SLM Ti-6Al-4V substrates were airbo...

Introduction: Video-assisted thoracic surgery (VATS) is now commonly used for primary spontaneous pneumothorax. In the present study we compared the outcomes of this technique with those obtained by conventional thoracotomy.Material and Methods: In this cross-sectional stud, forty patients were enrolled into two groups: VATS (n=20) and thoracotomy (n=20). In both groups the blebs were resected ...

This article is a brief overview of the evolution of the U.S. Air Force Dental Service with special emphasis on the simultaneous development of the specialty of prosthodontics within the Dental Service. Of special note is a review of the outstanding Air Force Training programs and Area Dental Laboratory system.

Dental personnel, other than dentists, must be trained to place sealants to provide this much needed service cost-effectively to the numbers of children who require it. A program to train Air Force dental technicians (equivalent to dental assistants) to place sealants with assistance using the Vac-Ejector Moisture Control System (Whaledent International, New York, NY) for isolation was reported...

Attrition, erosion, and abrasion result in alterations to the tooth and manifest as tooth wear. Each classification corresponds to a different process with specific clinical features. Classifications made so far have no accurate prevalence data because the indexes do not necessarily measure a specific etiology, or because the study populations can be diverse in age and characteristics. Tooth we...

Studying dental ontogeny in mammals can provide valuable insight on the evolution of their masticatory apparatus and their related adaptations. The multiple acquisitions of a prolonged to continuous growth of teeth in herbivorous mammals in response to high abrasion represent an intensively investigated issue. However, the ontogenetic and architectural patterns associated with these repeated de...
