| Research Abstract |
The aim of this study was to observe morphological changes in the gingival microvasculature after tooth preparation. The conventional dental air turbine and ultrasonicmethods were examined as a way of tooth preparation. To visualize the changes in the gingival vasculature, a corrosion resin cast was used and visualization performed with a scanningelectron microscope. Our observations suggest that the use of the ultrasonic wave instrument caused minimum damage compared to the use of the dental air turbine. Therefore, in terms of protecting the microcirculatory system in the gingival tissue during tooth preparation, the ultrasonic wave instrument is useful.
