Variability in Tooth Color Selection by Different Spectrophotometers: A Systematic Review

Objective: The objective of this study is to evaluate the variability in precision and reliability tooth color selection among different spectrophotometers. Methods: A search was performed following databases: MEDLINE (PubMed), Google Scholar, Scopus, Web Science. manual also based on reference lists relevant articles. Screening, data extraction, quality assessment were independently duplicate. In strategy, medical subject heading (MeSH) words used PubMed, free terms for titles abstracts each article. Each keyword separated by Boolean operator OR later be combined with AND. All three authors involved inclusion criteria, bias assessment. risk vivo studies parameters assigned Newcastle–Ottawa tool, vitro categorized applying modified ARRIVE CONSORT criteria. There great heterogeneity experimental design articles that included: however, no article mentioned or adhered indications given ISO_TR_28642_2016 standard measurement. Six included, two provided repeatability spectrophotometers, repeatability, one reliability. Results: process using PRISMA flow chart. yielded 714 studies. Of these, 88 duplicates excluded. total 579 excluded because their did not meet eligibility full texts other 47 examined, which led exclusion 39 Two remaining eight after criteria six included systematic review, examined Conclusion: SpectroShade Micro VITA Easyshade show better precision, but they have significant advantages protocol registered PROSPERO (the international prospective register reviews) under number CRD42021268853.
