Dental caries is a worldwide condition and its childhood’s most common chronic disease. Pulpectomy is the eligible treatment to deciduous teeth with pulp necrosis, aiming to maintain primary teeth functional until it’s exfoliation. Aim: to develop a systematic review of in vivo and in vitro studies that compared hand files and automated files, assessing the filling quality of the two systems in primary teeth. Data regarding instrumentation time, cleaning efficacy, shaping ability and filling time were also assessed. Methods: a systematic search was made in Pubmed, Embase, Cochrane Library, Scopus, Google Scholar and Open Grey databases, besides a manual search in 10 pediatric dentistry’s journals from the last 6 years. Results: 958 studies were selected for first assessment. After applied inclusion and exclusion criteria and duplicates removal, 43 studies were selected for complete screening: 14 clinical trials and 29 in vitro. Metanalysis was made regarding filling quality, instrumentation time and filling time, from data available from the clinical trials. Motordriven files showed better results, with statistical difference from hand files. Conclusion: automated endodontic files showed better filling quality than hand files in primary teeth. The results showed that they also provide less working time for instrumentation and filling and better root shaping ability, but the authors did not find difference between systems in cleaning efficacy.
