摘要

目的评价不同口腔卫生器械对修复体的刮伤、根面牙垢去除效果。材料与方法在本研究中，我们分析了20个拔除的牙齿表面，并安装了全金属冠固定修复体。有四组，每组5个样本。每组采用不同的口腔卫生工具进行处理:5个表面采用标准的Gracey管处理，5个表面采用超声探头和压电换能器处理，5个表面采用超声探头和磁致伸缩换能器处理，5个表面采用甘氨酸粉末空气抛光处理。结果与结论通过扫描电镜和专用软件处理图像的对比分析，表明甘氨酸粉空气抛光是牙龈下牙垢清除的首选方法，并且比其他方法能更好地保存牙龈下牙垢。

Il mantenimento della riabilitazione protesica: analisi morfologica in vitro con differenti sistemi di decontaminazione

Objectives

The aim of this experimental in vitro study was to evaluate the effects (scratching, tartar removal from root surfaces) on dental prostheses of different oral hygiene instruments.

Materials and methods

In this study we analyzed 20 surfaces of extracted teeth fitted with fixed prostheses with complete metal crowns. There were four groups of five samples. Each group was treated with different oral hygiene tools: five surfaces were treated with standard Gracey curettes, five with an ultrasonic handpiece and piezoelectric transducer, five with an ultrasonic handpiece and magnetostrictive transducer, and five with glycine powder air polishing.

Results and conclusions

The comparative analysis of SEM and dedicated software-elaborated images shows that glycine powder air polishing is the treatment of choice for the removal of subgingival tartar and that it allows better preservation of tissues than the other instruments tested.
