Abstract

The Orbison ultrasonic instrument and the Cavitron ultrasonic dental unit were compared for the smoothness of the root surfaces they produced. Twenty teeth were analyzed with the scanning electron microscope and classified as to rough or smooth. Both instruments produced similar degrees of smoothness on the root surfaces with minimal scarring. Application of these instruments to the root surface apical to the epithelial attachment produced residual smearing of some of the collagenous fibrils.

摘要

对奥比森超声仪器和卡维特龙超声牙科设备所产生的牙根表面光滑度进行了比较。用扫描电子显微镜对20颗牙齿进行了分析，并将其分类为粗糙或光滑。两种仪器在牙根表面产生的光滑度相似，疤痕极少。将这些仪器应用于上皮附着根尖的牙根表面时，会使一些胶原纤维产生残留涂片。
