Changes in the Dental Tissues Due to Cavity Preparation Using a Turbine Handpiece

DENTAL CAVITY MYIASIS DUE TO WOHLFAHRTIA MAGNIFICA

A 79 year old fanner referred to a dental clinic because of toothache for one week. After extraction of a painful tooth, three larvae, 1.5 cm in length emerged from the dental cavity. Morphological study of the larvae proved them as W. magnifica. This is the first report of dental cavity myiasis from Iran.

Relationships between tissue properties and operational parameters of a dental handpiece during simulated cavity preparation

A preliminary study was conducted on the development of an intelligent dental handpiece with functionality to detect subtle changes in mechanical properties of tooth tissue during milling. Such equipment would be able to adopt changes in cutting parameters and make real-time measurements to avoid tooth tissue damage caused by overexertion and overextension of the cutting tool. A modified dental...

Optimum 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...

Computational 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...
