 	abstract = "Objective: A systematic review and meta-analysis were performed to evaluate the color change, risk and intensity of tooth sensitivity (TS), risk of gingival irritation (GI) and patient’s satisfaction comparing whitening strips versus dental bleaching in adult patients of any age made at home or in office.
 Methods: On August 2017 the literature was elletronically searched in MEDLINE via PubMed, Cochrane Library, Brazilian Library in Dentistry, Latin American and Caribbean Health Sciences Literature database (LILACS) and citation databases, Scopus and Web of Science. Abstracts from International Association for Dental Research (IADR) (1990–2017) unpublished and ongoing trials registries, dissertations and thesis were also searched. Study selection: It was selected relevant articles that evaluated parallel and split-mouth Randomized Clinical Trials (RCTs) that compared whitening strips versus dental bleaching made at home or in office in adult patients of any age group. All articles were published only before August 10th, 2017. 4586 studies were identified and two reviewers removed the duplicates, title and abstract screening, remaining 14 studies to be included on analysis. As Meta-analysis was conducted for color change in objective scale (ΔE*) and subjective scale (ΔSGU), risk and intensity of TS and risk of GI with Visual Analog Scale (VAS), and patient’s satisfaction using random effects model. No significant difference in ΔSGU, risk and intensity of TS, risk of GI and paient’s satisfaction was observed (p > 0.05). However in ΔE* evaluation, color change was higher on the tray group with carbamide peroxide when compared to strips group. Conclusion: Although no difference was identified in the comparative treatments, this result should be interpreted with caution in view of the existence of few ECRs comparing supervised bleaching treatments with whitening tapes with low risk of bias. Clinical Relevance: Despite the equivalent effectiveness among the bleaching treatments evaluated, on ΔE* evaluation, there was higher color change for at-home with carbamide peroxide group. However, this study cannot confirm this result due to the high varibiality of the protocols and the presence of few studies with low risk of bias.",
