In-office tooth bleaching is an effective, safe and popular method among patients looking for a more beautiful smile. Objectives: To evaluate through a systematic review and meta-analysis whether in-office tooth bleaching improves the quality of life of patients undergoing treatment. Materials and Method: Using electronic databases MEDLINE (via PubMed), Cochrane Library, Brazilian Dental Library, Latin American and Caribbean Health Sciences Literature (LILACS) and citation databases (Scopus and Web of Science) were selected. articles that evaluated the quality of life of patients undergoing inoffice tooth bleaching, including only randomized clinical trials and split mouth in humans based on their titles and without restriction of publication date or language. The start date of the research studies was April 15, 2021 and received an update on July 14, 2021. Two review authors selected studies that met the inclusion criteria. Relevant information about study design, participant interventions, and outcomes was independently extracted using custom extraction forms. The same reviewers assessed the quality of studies using the Cochrane Collaboration tool to detect risk of bias. Statistical analysis: Data were analyzed using Rstudio statistical software, meta-analyses were performed on eligible studies and summarized by calculating the standardized mean difference for continuous data and the hazard ratio, and the results were expressed in graphs. Results: Two reviewers selected studies that met the inclusion criteria. Of the 68 full-text articles evaluated, 17 articles remained and were analyzed. Of these, one article was at high risk of bias, three were at low risk, and the other 13 were at uncertain risk. The meta-analysis showed that of the eligible studies we had 50% satisfaction after in-office tooth bleaching. Conclusion: There was an improvement in the quality of life of patients who underwent in-office tooth bleaching.
