Background: Aim of this systematic review was to evaluate the incidence of post-operative pain after single visit root canal treatment using single file rotary and reciprocating file systems. Objective of this article is to compare the difference between single and multiple file systems on the incidence of postoperative pain after single visit root canal treatment. Data Source: Two internet sources of evidence were used in the search of appropriate papers satisfying the study purpose: the National Library of Medicine (MEDLINE PubMed) and Google Scholar. Study Eligibility Criteria: The following criteria was used to select the studies: 1. The inclusion criteria were articles in English having detailed summary were searched, and studies published between 1st January 2000 to 31stOctober 2017 were selected, in-vivo studies which included single and multiple file systems using greater taper instruments in endodontically treated teeth were searched. 2. The exclusion criteria were review, abstracts, letters to editors, In-vitro studies and studies assessing postoperative pain in endodontically treated teeth with parameters other than instrumentation. Intervention: Single visit root canal treatment using single file system. Results: Total of 26 articles were searched out of which 23 articles were selected. The papers were screened, as a second step. Titles, abstract and full text were screened; 2 articles were excluded while screening the titles, one article was excluded while screening the abstract and 7 were duplicates. Papers were obtained when they fulfilled the criteria of the study aim. However, only articles where single visit root canal treatment, with instrumentation using single file systems having different kinematics such as rotary or reciprocating motions of endodontic file systems on post operative pain was assessed and selected. Finally, a total of 13 articles were included which were selected for this review. Conclusion: Irrespective of the number of appointments, that is single visit or multiple visit root canal treatment, reciprocating single file systems proved to be better than continuous rotary single file and multiple file systems with respect to post-operative pain. Reciprocating instrument systems create less debris extrusion during instrumentation, which may be the cause of reduced post-operative pain
