Abstract

Background: An irreversible hydrocolloid impression material combined with two different doses of chlorhexidine solution is tested for dimensional change and tearing strength. The aim of this study is to evaluate the impact of adding chlorhexidine with 2 different available concentrations on alginate impression material. Materials and Methods: According to the manufacturer's instructions, the irreversible hydrocolloid specimens is made and divided into 3groups (Group 1 is mixed with tap water as a control group, Group 2 is mixed with 0.12 chlorhexidine, and Group 3 is mixed with 0.2 chlorhexidine). Testing is done on the change in dimensions and the tearing strength. Results: Lesser dimensional change is observed at group two and is non-significant, and the group three is significantly more dimensionally stable when compared with group one, tearing strength of group one and two is nearly the same while the group three is more resistant to tear and the difference is significant Conclusion: The dimensional stability and tearing resistance of chlorhexidine self-disinfecting irreversible hydrocolloid impression material may vary greatly.

水与氯己定混合藻酸盐压印材料的撕裂强度及尺寸稳定性比较

背景:& # x0D;采用两种不同剂量的氯己定溶液，对不可逆水胶体印模材料进行了尺寸变化和撕裂强度测试。本研究的目的是评价两种可用浓度的氯己定对海藻酸盐印模材料的影响。材料与方法: 根据厂家说明制作不可逆水胶体标本，分为3组(1组与自来水混合作为对照组，2组与0.12氯己定混合，3组与0.2氯己定混合)。测试了尺寸变化和撕裂强度。结果:& # x0D;第2组的尺寸变化较小，不显著，第3组的尺寸稳定性明显高于第1组，第1组和第2组的撕裂强度几乎相同，第3组的抗撕裂性更强，差异显著结论:& # x0D;氯己定自消毒不可逆水胶体印模材料的尺寸稳定性和抗撕裂性可能存在较大差异。
