Analyzing the Effect of Disinfection Additives on the Linear Dimensional Stability of Dental Alginate Impressions: A Quasi-Experimental Comparative Study

Launched by ALTAMASH INSTITUTE OF DENTAL MEDICINE · Mar 26, 2025

ClinConnect Summary

This clinical trial is looking into how different disinfecting agents can affect the stability of dental alginate impressions, which are materials commonly used to create molds of teeth. These impressions can sometimes change shape or become contaminated, which can lead to issues with the accuracy of dental work. The study will test various disinfectants, including Chlorhexidine, Chitosan, Silver Nitrate, and others, to see if they can help maintain the shape of the alginate while also reducing the risk of infection.

To participate in this trial, individuals need to have dental stone casts that are free from defects like cracks or bubbles that could interfere with the results. It is important that the impressions are intact and properly made. Participants will not need to take any specific actions beyond what is required for regular dental procedures, and the study aims to improve both infection control in dental practices and the quality of dental prosthetics. This trial is not yet recruiting, but it opens the door for advancements in dental care.
