A Laboratory Investigation of the Effectiveness of Different Acids in Removing Mineral Trioxide Aggregate From Simulated Root Canals

Year: 2025

Type: article

Abstract: The aim was to compare the effectiveness of acids in removing MTA from root canals. Fifty acrylic blocks were filled with MTA and divided into groups - 10% hydrochloric acid; 10% citric acid; 2% acetic acid; 2% carbonic acid and 20% tartaric acid. MTA was removed with the acids, plus ultrasonic tips and rotary files. Outcomes were measured as pre- and post-operative weight differences, luminance differences and working time to regain length or form ledges. Weight differences varied significantly - citric acid was highest; hydrochloric acid was lowest and others were not statistically different from each other. Luminance did not differ significantly between groups but varied significantly with distance from the apex - hydrochloric acid and carbonic acid were lowest at 1 mm from the apex. Working times differed significantly - hydrochloric acid took longer than other acids except citric acid. Overall, the most effective acid was citric acid. The least effective was hydrochloric acid.
