Background: The purpose of this clinical study was to assess the success of infra-inguinal revascularization in the treatment of lower limb ischemia in patients hospitalized with trauma. Materials and methods: Fifty seven consecutive patients admitted with trauma, during April 2000- March 2005, underwent bypass operations in the Shohada Hospital. Records of all patients were reviewed. Late con...
Aim: The aim of this study is to evaluate the retreatability bioceramic sealers (Endosequence BC, Totalfill MTA-Fillapex) used with single cone obturation technique. Materials and methods: Root canal forty rooted human mandibular premolar teeth were prepared ProTaper Next rotary system up X3 obturated technique (n=10) using endosequence BC (A), Totallfill (B), MTA-Fillapex (C) Zinc oxide...
INTRODUCTION The purpose of this in vitro study was to assess the apical microleakage of AH26 sealer when three different root canal irrigant regimens were used. MATERIALS AND METHODS Eighty single-rooted human teeth were randomly divided into three experimental (n=20) and two control groups (n=10). NaOCl was used as irrigant during instrumentation, and apical patency was ensured in all teeth...
PURPOSE We aimed to evaluate the effectiveness of the Fogarty balloon application in dislodging residual thrombus at the sheath entry point in a graft by using single apex puncture to declot thrombosed hemodialysis loop grafts. MATERIALS AND METHODS The apex puncture technique was used in 520 cases to declot 376 hemodialysis loop grafts (male/female, 150/226; mean age, 58 years). The Fogarty ...
Background: Dialysis access procedures and complications are important causes of morbidity and hospitalization for chronic hemodialysis patients. Ideally, any patient undergoing hemodialysis should receive an autogenous fistula that can be accessed throughout the patient's life. In patients with primarily unsuitable or secondarily surgically-exhausted veins, a prosthetic graft can be performed....
INTRODUCTION The purpose of this study was to assess canal preparation outcomes in vitro by novice clinicians after standardized teaching sessions. METHODS All students received a training session. In experiment 1, twenty canals of mandibular molars were prepared with GT and ProTaper rotaries by 10 students. Standardized radiographs were exposed before and after canal preparation, and canal c...
Although arterialovenous fistulae (AVF) is considered to be vital for chronic kidney disease (CKD) patients, but they may cause complications and problems. For instance they may fail soon after their creation. The most important cause of failure in these cases is intrafistula thrombus formation. Whereas anti-platelet drugs are not routinely used after fistulae creation, we conducted this stud...
Background and purpose: Development of arteriovenous fistulas (AVF) is one of the major advances in the management of patients undergoing hemodialysis. Patency rate of these fistulas and the factors influencing them is of great importance to reduce the costs and rate of repeated hospitalization. Materials and methods: In a five-year study 72 patients who had native AVF were followed for one ye...
objective: knowledge about the internal anatomy of the root canal and apical foramen is a critical prerequisite for root canal therapy and is necessary for the success of endodontic treatment. this study aimed to determine the distance of apical foramen from the anatomical apex and apical constriction, evaluate the deviation of apical foramen from the anatomical apex and specify the most common...
