Microleakage of cervical cavities prepared by an Er:YAG laser or a high-speed handpiece, after restoration using resin composite
Objectives: The purpose of this in vitro study was to evaluate the microleakage of cervical cavities prepared by Er:YAG laser or high-speed hand piece and bur. Methods: This in vitro experimental study was performed on 40 sound permanent third molar teeth randomly assigned into two equal groups (n=20). In the first group, high-speed hand piece and bur and in the second group Er:YAG la...
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 کاملIn vitro study of anti-suck-back ability by themselves on new high-speed air turbine handpieces.
The anti-suck-back ability of five new high-speed air turbine handpiece models was evaluated in this study. First, suck-back pressure with water displacement within a glass tube was measured. Next, under three different conditions, how many on-off times it takes before fluorescent stains became visible on a piece of gauze at the exhaust vent was counted and the presence of fluorescent stains on...
متن کاملComparing Postoperative Complications of Impacted Third Molar Extraction between Piezosurgery and Conventional Surgical Handpieces
Background and purpose: Conventionally, rotary devices were used for bone surgery. Recently, new techniques have been proposed such as piezosurgery. The prevalence of impacted teeth which should be removed is high. There are different techniques for bone removal that are associated with specific complications. This study compared the postoperative complications of impacted third molar extrac...
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...
