\begin{abstract}
ABSTRACT Objective: In this study, the literature was systematically
reviewed to investigate the effect of hydrogen peroxide concentrations
on bleaching effect and tooth sensitivity. Data Sources: Electronic
databases were screened, and hand searched. Searched electronic
databases are PubMed, Scopus, Cochrane Library, Ovid Medline, Elsevier
science direct, Wiley online library, Grey literature, Embase. Materials
and Methods: A systematic review on controlled clinical trials MeSH
terms used are (hydrogen peroxide) AND (bleaching) AND (tooth
sensitivity). A trial on the bleaching effect and tooth sensitivity with
various hydrogen peroxide concentrations were included. PRISMA
guidelines were followed, and the PICO model was used. Cochrane risk
assessment tool for randomized controlled trials was used. Results: A
total of 5 articles fulfilled the inclusion criteria. The analysis
showed that high hydrogen peroxide concentration has a better bleaching
effect accompanied by tooth sensitivity. Low hydrogen peroxide
concentration also has a bleaching effect slightly minimal from the
former, followed by less tooth sensitivity. Conclusion: This study
concludes that the hydrogen peroxide with higher concentration is
effective in bleaching and with lower concentration is less likely to
produce tooth sensitivity KEYWORDS: h2o2, bleaching, sensitivity, tooth
shade, aesthetic dentistry%
