Effect of ultrasound on dental hard tissues (electronic and microscopic study)
Abstract
Currently, ultrasound is successfully used in clinical dentistry. Were clearly identified areas of its most effective application. However, concern is the risk of such complications as enamel and dentin hypersensitivity with subsequent involvement of dental hard tissues in the inflammatory process. In an experimental study on the mongrel dogs the characteristic structure of the state of dental hard tissues (enamel and dentin) before and after exposure to ultrasound of different intensities (the exposure time 20 seconds). Application of ultrasound of small intensity (1 W/cm²) showed that electron-microscopic picture of the enamel and dentin has not changed. Action of ultrasound of large intensity (2 W/cm²) has revealed feebly marked damaging effect in the form of microcracks enamel and tubules of dentin reducing the number, along with the reduction of the number of processes dentins odontoblasts.
