Abstract

A 6-month study project utilized four human subjects and a total of 63 biopsies which were obtained from gingiva treated by hand scaling, Alpha-Sonic scaling and Cavitron. These were compared with controls (untreated specimens). Microsections of soft tissues taken immediately and after 1 and 2 weeks were evaluated. The clinical acceptability of Alpha-Sonic as a working tool for periodontal scaling is to be noted.

摘要

一个为期6个月的研究项目使用了4名人类受试者，共获取了63份活检样本，这些样本取自接受手工洁治、超声洁治和超声治疗仪治疗的牙龈组织。将这些样本与对照组（未治疗的样本）进行比较。对即时采集以及1周和2周后采集的软组织切片进行评估。值得注意的是超声洁治作为一种牙周洁治工作工具的临床可接受性。
