Introduction: The purpose of this research was to use cone‑beam computed tomography (CBCT) to examine the efficacy of hand and rotary files, manual dynamic agitation, and inactive ultrasonic actions in removing Ca(OH) 2 from root canal surface when used in conjunction with two distinct vehicles. Materials and Methods: Using the ProTaper Gold file system, the root canals of 100 mandibular premolars were cleaned and shaped up to file F2, and then filled with either Ca(OH) 2 + saline or Ca(OH) 2 + camporated monochloro-phenols. After 7 days of incubation, CBCT was used to do a prevolume analysis. Several forms of agitation were used to successfully remove calcium hydroxide (K‑ and H‑file, ProTaper Gold rotary file, passive ultrasonic irrigation (PUI), and manual dynamic agitation). CBCT was used to reevaluate the volumes after the fact, & the percentage of change was determined the Post Hoc Tukey test, One-way ANOVA, & the Dunn test were utilized to analyse the data statistically. Results: Saline‑based Ca (OH) 2 was little simple to be separate than camporated monochloro-phenols(CMCP)‑ based group. When the agitation systems were compared, H‑file in both the groups removed more calcium hydroxide from root canals than other systems(P < 0.01). Conclusion: The H‑file system and PUI were more effective than the K‑file, rotary, and manual dynamic agitation methods in eliminating calcium hydroxide from root canals. However, the saline‑based calcium hydroxide was easier to be removed than camphoro monochlorophosphate. [ABSTRACT FROM AUTHOR] |
