Purpose: This in vitro study compared the temperature rise in the pulp chamber during fabrication of provisional resinous restorations on three types of teeth by a direct method. Materials and Methods: The tip of a thermocouple was positioned into the pulp chamber of thirty intact extracted human teeth. Then the teeth were divided into three different tooth groups (incisor, premolar, molar) and...

OBJECTIVE The aim of this study was to examine the temperature changes in the pulp chamber during cavity preparation with the Er:YAG laser (2940 nm) with a very short pulse (VSP). MATERIALS AND METHODS Nine groups of 10 intact molars each were used. One root of each sample was amputated and a thermocouple was inserted into the chamber. Class V cavity preparation in enamel was performed, and t...

Stent thrombosis and lead perforation are important differentials for patients presenting with chest pain following recent coronary stent insertion pacemaker insertion. In this report, we describe an unusual case of a 78-year-old male who presented sharp one week after admission posterior ST-elevation myocardial infarction (STEMI) subsequent Mobitz type II block, which he received primary percu...

BACKGROUND At the end of fixed orthodontic treatment, the remnant of adhesive should be eliminated from the tooth surface. The purpose of this study was to compare the effect of three methods of removing adhesive on enamel surface roughness, dental pulp temperature, and also on the time spent. MATERIALS AND METHODS The brackets on 90 extracted teeth were debonded using bracket removal pliers....

UNLABELLED The purpose of the study was to compare temperature rise during polymerisation of resin based composites (RBCs) with two LED light curing units (LCUs) compared to a halogen control light. METHODS Forty-five extracted molars, patients aging 11-18 years were used. Thermocouples (TCs) were placed in contact with the roof of the pulp chamber using a 'split-tooth' method. Teeth were pla...

BACKGROUND Cardiac perforation is a feared complication of implantable cardioverter-defibrillator (ICD) lead implantation because of the potential for significant morbidity and mortality. Predictors of perforation and the severity of associated adverse events have not been well studied. We sought to identify predictors of cardiac perforation from ICD lead implantation and subsequent outcomes. ...
