Quantitative comparison of calcium hydroxide removal by endoactivator, ultrasonic and protaper file agitation techniques: An in vitro study

Calcium hydroxide (CH) dressing residues can compromise endodontic sealing. This study aimed to evaluate the amount of remaining CH in root canals after mechanical removal by four groups of irrigation techniques including needle irrigation only, ProTaper file, EndoActivator, and ultrasonic file. Fifteen extracted single-rooted teeth were collected and used… CONTINUE READING
