Pneumomediastinum secondary to use of a high speed air turbine drill during a dental extraction.
Pneumomediastinum and subcutaneous emphysema of the neck and thorax can occur exceptionally following a dental procedure. A case is described of acute subcutaneous emphysema of the lateral region of the neck and thorax associated with pneumomediastinum during a dental extraction with an air and water cooled turbine burn drill.
متن کاملEffectiveness of high speed instrument and air abrasion on different dental substrates.
The aim of this study was to compare the effectiveness of high speed (HS) and air abrasion (AA) instruments on groups of teeth (deciduous, permanent, bovine), in terms of preparation time, topography and presence of smear layer. Each group consisted of 5 teeth that had their buccal/lingual surfaces prepared by using either HS or AA. All procedures were standardized and timed. The teeth were the...
متن کاملComputational Approach to Design the High-speed Dental Air-turbine Handpiece
The high-speed dental air-turbine handpieces are widely used in the dentistry as a tool for cutting and drilling a tooth. The advanced existing high-speed dental air-turbine handpieces were investigated to design the high performance dental air-turbine handpiece. The coupler and air-turbine of the dental air-turbine handpiece was designed using computational analysis. The computational domain o...
متن کاملUnexpected Hazards with Dental High Speed Drill
An expected accident can happen at any time during a routine practice in the dental office due to the types of instruments used. One of the instruments used in routine dental practice is a high speed drill and a bur. If Personal Protective Equipment (PPE) is not practiced at any time in the dental office, very serious injuries could easily happen to the clinician, staff or to the patient.
متن کاملOptimum Design of the Air-turbine for the High-speed Dental Air-turbine Handpiece Using Design of Experiment
High-pressure air enters the air-turbine of the dental handpiece and strikes the blades to drive the impeller. The air-turbine has impeller and the air tube is connected to the air-turbine housing. The flowfield of the air-turbine were investigated for the optimum air-turbine design using ANSYS CFX. The objective of the research was to find an optimum design variables for the air-turbine to inc...
