There is a continuing concern over the potential for cross-contamination of viral infections such as AIDS by means of dental impressions. This investigation compared the effects of various viricidal agents on the accuracy of irreversible hydrocolloid and silicone impressions made of single-unit and full mandibular arch models. Measurements on casts made from the treated impressions were compared with the corresponding measurements on casts made from untreated impressions. The results of this study led to the conclusions that there was no preferred disinfectant with respect to dimensional stability for the irreversible hydrocolloid, condensation silicone, or vinyl polysiloxane impression materials tested, and there was no difference in the accuracy of the casts obtained either by spraying with or immersion in any of the disinfectants tested. Therefore using the disinfectants described with either the immersion or spray techniques will not significantly affect the dimensional accuracy of cats made from treated impressions.
人们一直担心诸如艾滋病等病毒感染会通过牙印模发生交叉污染。本研究比较了各种杀病毒剂对由单颗牙模型和全下颌牙弓模型制成的不可逆水胶体印模和硅橡胶印模准确性的影响。将经处理印模制成的模型测量结果与未经处理印模制成的模型相应测量结果进行比较。本研究结果得出以下结论：对于所测试的不可逆水胶体、缩合型硅橡胶或乙烯基聚硅氧烷印模材料，就尺寸稳定性而言，没有首选的消毒剂，并且通过喷洒或浸泡在任何一种所测试的消毒剂中获得的模型准确性没有差异。因此，使用所述消毒剂采用浸泡或喷洒技术均不会显著影响经处理印模制成的模型的尺寸准确性。
