Background: The aim of this study was to analyze the influence of good metabolic control, based on glycosylated hemoglobin (HbA1c) levels, on oral health status and the need for orthodontic treatment in children.
Methods: This cross-sectional study was carried out at the Dental Clinic of the University of Salamanca (Spain) during the years 2020 and 2024. A total of 260 children with type 1 diabetes (aged between 6 and 12 years) participated.
Statement Of Problem: Several formulas to measure color differences have been proposed to improve the correlation between color measurements and visual perception. Despite the progress obtained, equating between formulas is complex, rendering the exchange of information in scientific papers difficult.
Purpose: The purpose of this study was to determine the relationship between the results provided by classic CIELab (ΔEab∗) and the CIEDE2000 (ΔE00) formulas in the natural tooth color space using the Bland and Altman limits of agreement, to use this relationship to establish the equivalences between the tooth color thresholds of acceptability and perceptibility of both formulas, and to evaluate whether the relationship between ΔEab∗ and ΔE00 is modified depending on the axis on which the changes occur.
Statement Of Problem: Many color specification systems and color differences have been proposed to improve the correlation between color measurement and visual perception. Although color differences can be quantified using either the CIELab formula (ΔE*(ab)) or the recently introduced CIEDE2000 formula (ΔE00), which captures the perceived color difference better is unknown.
Purpose: The purpose of this study was to evaluate the CIELab and CIEDE2000 formulas to determine which best reflects the difference in color perception and whether color perception differs by sex.
