Methods This overview from systematic reviews will be reported according to the PRIO Statement (Preferred Reporting Items for an overview of systematic reviews) (Bougioukas et al., 2018). Study Sources A systematic search from the available studies will be conducted in the electronic databases MEDLINE/PubMed Cochrane Library, Scopus, Embase, Web of Science, and Epistemonikos. Gray literature will be searched in the OpenGray database. Besides, the reference list from the potentially eligible reviews will be tracked to verify all the relevant reviews that might not be identified during the database search. There are no language and publication date restrictions for systematic reviews inclusion. 1. Search strategy The search strategy was developed to databases MEDLINE/PubMed and was adapted to the other databases consulted, as described below: ((“primary teeth” OR “primary tooth” or “deciduous teeth” or “deciduous tooth” or “tooth, deciduous” OR “primary dentition” or “baby teeth” OR “baby tooth” OR “pediatric dentistry”) AND (“critical appraisal” OR “systematic review” OR “meta-analysis”)) The results from the different databases were crossed through the EndNote program, reference manager, in order to locate and eliminate duplications. 2. Eligibility Criteria Initially, the titles and abstracts of potentially relevant studies identified in databases will be independently evaluated by two reviewers (TMR and TKT). A researcher with experience in systematic reviews in Pediatric Dentistry (DPR) will resolve cases of conflict or doubt. The articles will be considered eligible when they followed the inclusion criteria: (1) To investigate the treatment of pediatric dentistry patients; (2) To be a systematic review. After the first evaluation, the reviews that meet the inclusion criteria will be completely reviewed, being then considered ineligible those that present at least one of the following exclusion criteria: (1) Do not follow the methodological outline of a systematic review; (2) To be in deciduous teeth; (3) To be about carious injury management; (4) Do not be in a special patient group. Moreover, if there were systematic review updates, those with more complete data will be considered. 3. Data Extraction The required information from eligible studies will be collected by the two reviewers independently (TMR and TKT) and a third reviewer checked all collected data (DPR). For each included study, the following data were systematically recalled: publication details (authors, year and journal), registration protocol (yes or no), a subject covered, number of articles included, used databases, search date, number of reviewers, languages considered, types of studies included, outcomes analyzed, analysis of quality and risk of bias (yes or no and which tool was used), type of analysis (qualitative or quantitative) and number of citations up to the date of the final search. 4. Assessment of methodological quality and risk of bias Both two reviewers will independently perform the quality and risk of bias analyses. The methodological assessment will be carried out using the AMSTAR-2 tool (Shea et al., 2017), while the ROBIS tool (Whiting et al., 2016) will be used to assess the risk of bias. Doubts and discrepancies were discussed and, when consensus was not possible, the third reviewer will be consulted. 5. Assessment of the quality of evidence and strength of recommendation The GRADE tool will be used to assess the level of evidence and the rate of recommendation for each topic included in systematic reviews. The level of evidence will be classified as high, moderate, low, or very low; while the rate of treatments recommendation will be weighted as strong or weak.
