Orthodontic white spot lesions (WSLs) can affect patients’ aesthetic satisfaction? A spectrophotometric approach
The aim of this in vivo study was to evaluate the colourimetric
changes between sound enamel and post orthodontic WSLs and to
correlate these findings with human eye colour perception threshold
using spectrophotometry. Experimental approach Seventy-six
permanent teeth with post orthodontic WSLs in 12–16 years old
patients were evaluated in this in vivo study at “Sapienza”University
of Rome. The spectrophotometric differences in colour (ΔL*, Δa*,
Δb*; Color Difference ΔE00; Whiteness Index ΔWIO) between
