Comparing the Removal of Intracanal Medicament from Root Canal System using Four Different Irrigation Techniques: A Systematic Review

Abstract

Introduction: To eliminate intracanal calcium hydroxide (Ca[OH]2) medication from  root canal, this systematic review compared the results of in vitro experiments using needle irrigation, ultrasonic irrigation, sonic irrigation, and laser activated irrigation techniques.

Methods: The population, intervention, comparison, and outcome strategies were taken into consideration when developing the research question. Cochrane, PubMed, Google Scholar, Ebsco, and Embase were searched for relevant material using a computer. To find pertinent articles, a random search of the identified papers' reference lists was done. The studies that meeting the inclusion criteria were evaluated critically by two reviewers. Both reviewers conducted separate assessments of the studies' risk of bias. A manual search using online resources was also carried out. To find further publications that satisfied the study's eligibility requirements, cross-reference lists of the selected studies were  examined.

Results: Following study selection, 4093 publications were found using a database search; 161 full-text articles were assessed for eligibility. After fulfilling the inclusion requirements, eight of them were added to the systematic review. Because of the significant variation in the methods, a meta-analysis was not practical. The screening process was conducted by two reviewers. The first step was evaluating the publications based on their titles and abstracts. After that, full-text papers were obtained for further assessment to ensure they met the study's specifications.

Conclusions: We came to the conclusion that it did not have any  statistically significant difference         between the root canal and the removal of the CH based on the available data (P>0.05). The capacity to remove intracanal medicines was highest with SWEEPS and lowest with syringe-needle irrigation (P<0.05). The intracanal medicament could not be entirely removed using any method. SWEEPS technology fared better than the sonic and ultrasonic  systems in terms of removing intracanal medicines. Due to the limitations, small number of studies, and sample sizes, findings are needed additionally.
