based on the book chapter by Goran Benic and Irena Sailer Summary The visual appearance obtained after tissue reconstruction is an increasingly important aspect of orodental treatment, and hence of research. The esthetic aim is to achieve visual harmony between original and constructed elements. With a focus on metric assessment, the chapter offers guidance on the assessment of soft tissue levels and color matching, describing the scope and uses of ranking systems like the Copenhagen Index, Papilla Index and Implant Crown Esthetic Index, and the Pink/Pink and White Esthetic Scores. It describes how the common systems relate to different types of tissue and their optical, dimensional and surface characteristics, such as mucosal depth. While color match can be assessed using the naked eye, the growing demand for calibration and standardization makes electronic color analyzers more suitable, such as spectrophotometers, that use spectral analysis and CIE-Lab color coordinates and can be calibrated. Discussions cover all clinical parameters of interest and the factors that influence color match with the reconstruction material, such as mucosal thickness. The authors point out the need to make comparisons against healthy natural sites in the same patient, to standardize methods, minimize observer variations and ensure blind assessment. They also discuss how and when to establish baseline values to chart changes, and suggest suitable statistical analyses, with a view to publishing results the can be compared with relevant studies.
