Comparison between clinical and computerized methods for assessing gingival pigmentation.

Background And Objective: Digital computerized assessment can provide objective values for the measurement of gingival pigmentation. This study aims to compare the Commission Internationale de l'Eclairage Lab color space (CIELAB) values and the computerized intensity values (CIVs) from digital imaging with clinical evaluations using the Dummett-Gupta Oral Pigmentation Index (DOPI) for assessing gingival pigmentation in a multi-ethnic population.

Methodology: Digital photographs of 188 participants were taken using standardized parameters.
