Introduction: Given the importance of randomized clinical trials (RCTs) in the evidence-based approach in dentistry, the study aimed to conduct critical appraisal of dentistry RCTs of Iran published in English from 1999 until 2012. Materials and Methods: In total, databases of PubMED, ISI web of science and Scopus were searched using specific keywords (i.e., dental, dentistry, critical appraisal, clinical trial, evidence-based RCT, randomized clinical trial, Iran). After the elimination of duplicate articles, the 433 remaining articles were assessed, which led to the selection of 86 studies by employing the inclusion and exclusion criteria. Following that, the articles were evaluated using the revised version of Jadad scale. Results: In this research, mean jadad score was 5.33±1.73, and articles were at a moderate level (4 < jadad score <= 6). In total, 97.7 of the articles received the complete score for the eighth item (statistical analysis), whereas only 38 articles described the sample randomization method (44.2) and 33 articles mentioned the number of eliminated samples and its cause (38.4). According to the results, the most published clinical trials were related to periodontics (21 articles) and endodontics (19 articles). Moreover, the majority of the published articles were from Mashhad dentistry school(16 articles). Conclusion: According to the results of the study, the methodological quality of the Iranian English dentistry articles was generally at a medium level, which requires improvement. Emphasis on standard instructions in designing the studies and using review checklists during the complication of a research, along with holding educational relevant workshops, can considerably improve the quality of Iranian articles.
