A systematic review of visual and instrumental measurements for tooth shade matching
Chen, Hui / Huang, Jing / Dong, Xian / Qian, Jielei / He, Jiajing / Qu, Xinhua / Lu, Eryi
Objective: Common methods for matching tooth shade can be classified into two
categories: visual and instrumental measurements. This systematic review evaluated
these two methods in terms of precision and accuracy using the agreement percentage
rate.
Method and Materials: The following databases were searched for studies
comparing different shade-matching methods: MEDLINE (PubMed), Embase, and
Google Scholar. Reference lists of relevant articles were also searched. Screening, data
abstraction, and quality assessment were conducted independently and in duplicate.
Results: Twenty-six studies were included. Seventeen studies provided data on the
precision of the evaluated shade-matching methods, eight provided data on accuracy,
and one provided data on both precision and accuracy.
Conclusion: Instrumental
measurements using a spectrophotometer may provide the most precise and accurate
shade-matching outcomes. However, the limitations of the available articles suggest that
high-quality studies are still needed verify this claim.
