AI Article Synopsis
- The study evaluated the effectiveness of chlorhexidine mixed with irreversible hydrocolloid powder in reducing microbial contamination during dental impressions.
- It was conducted with 20 volunteers divided into two groups, using either 0.12% chlorhexidine or water for the impressions.
- Results showed that chlorhexidine significantly lowered microbial presence while maintaining the surface quality and dimensional stability of the resulting casts.
Article Abstract
This study aimed to evaluate whether chlorhexidine mixed with irreversible hydrocolloid powder decreases microbial contamination during impression taking without affecting the resulting casts. Twenty volunteers were randomly divided into two groups (n = 10) according to the liquid used for impression taking in conjunction with irreversible hydrocolloid: 0.12% chlorhexidine or water. Surface roughness and dimensional stability of the casts were evaluated. Chlorhexidine mixed with irreversible hydrocolloid decreased the percentage of microorganisms when compared with water (P < .001) but did not affect the surface quality or dimensional stability of the casts. Mixing chlorhexidine with irreversible hydrocolloid powder is an alternative method to prevent contamination without sacrificing impression quality.
