Ultrasound offers great potential in development of a noninvasive periodontal assessment tool that would offer great yield real time information, regarding clinical features such as pocket depth, attachment level, tissue thickness, histological change, calculus, bone morphology, as well as evaluation of tooth structure for fracture cracks. In therapeutics, ultrasonic instrumentation is proven effective and efficient in treating periodontal disease. When used properly, ultrasound-based instrument is kind to the soft tissues, require less healing time, and are less tiring for the operator. Microultrasonic instruments have been developed with the aim of improving root-surface debridement. The dye/paper method of mapping ultrasound fields demonstrated cavitational activity in an ultrasonic cleaning bath. Piezosurgery resulted in more favorable osseous repair and remodeling in comparison with carbide and diamond burs. The effect of ultrasound is not limited to fracture healing, but that bone healing after osteotomy or osteodistraction could be stimulated as well.
超声在开发无创牙周评估工具方面具有巨大潜力，该工具可实时提供有关临床特征的大量信息，如牙周袋深度、附着水平、组织厚度、组织学变化、牙石、骨形态，以及评估牙齿结构是否存在骨折裂缝。在治疗方面，超声器械已被证明在治疗牙周疾病方面有效且高效。如果使用得当，基于超声的器械对软组织损伤小，愈合时间短，且操作人员不易疲劳。为了改善根面清创，已开发出微超声器械。用染料/纸法绘制超声场显示，超声清洗槽中存在空化活性。与硬质合金和金刚石车针相比，压电手术能带来更有利的骨修复和重塑。超声的作用不仅限于骨折愈合，还能刺激截骨术或骨牵引术后的骨愈合。
