Abstract

The effects of high-temperature sterilization methods (boiling, dry-heating, autoclaving and chemiclaving) on the properties of four types of stone cast were determined. SEM observations were made of the cast surface before and after sterilization. High-temperature sterilization affected the properties of the stone casts. Boiling, dry-heating and autoclaving were considered to be unacceptable methods for sterilizing stone casts before making prosthetic restorations.

摘要

测定了高温灭菌方法（煮沸、干热、高压蒸汽灭菌和化学灭菌）对四种类型石膏模型性能的影响。在灭菌前后对模型表面进行了扫描电子显微镜观察。高温灭菌影响了石膏模型的性能。在制作修复体之前，煮沸、干热和高压蒸汽灭菌被认为是不可接受的石膏模型灭菌方法。
