Tooth whitening in children.
Although there are several case reports of vital tooth bleaching in children, there is limited clinical trial evidence of the safety or efficacy of this practice. Accordingly, a new clinical trial was conducted to evaluate the effects of 2 different bleaching systems, a 6.5% hydrogen peroxide strip system and a 10% carbamide peroxide tray system, in a population of preteens and teens. A total o...
متن کاملDevelopment of piezoelectric micromachined ultrasonic transducers
Piezoelectric micromachined ultrasonic transducers (pMUTs) are an example of the application of MEMS technology to ultrasound generation and detection, which is expected to offer many advantages over conventional transducers. In this work, we investigate pMUTs through novel design and fabrication methods. A finite element (FE) model, with original tools to measure device performance, was develo...
متن کاملTooth whitening: concepts and controversies.
Today's society dictates that it is the norm for people to have straight, white teeth. The demand therefore for tooth whitening in dental practice has increased exponentially over the last decade. A common approach to achieving this goal is by bleaching. This article discusses clinical aspects of dental bleaching by providing an evidence-based review of current literature. Topics covered includ...
متن کاملThe pH of tooth-whitening products.
Tooth whitening products may be in contact with intraoral structures for several hours or they may be used daily to whiten the teeth. Consequently, these products should have a relatively neutral pH to minimize potential damage. This study measured the pH of 26 commercially available tooth-whitening products. The pH of the different whitening products ranged from 3.67 (highly acidic) to 11.13 (...
متن کاملPiezoelectric ultrasonic micromotors
This thesis describes development of a new actuator technology for integrated machines of the future: piezoelectric ultrasonic micromotors. Ultrasonic motors o er the advantages of low speed, high torque operation without the need for gears. They can be made compact and lightweight and provide a holding torque in the absence of applied power due to the traveling wave frictional coupling mechani...
