Analysis of the oral cavity of human archaeological remains can provide essential information on the general health status of the person. The objectives of this paper are (i) to highlight an analysis of the oral state of the embalmed body of a 17th century female aristocrat with modern techniques of periodontal diagnosis and (ii) to provide a description of the therapeutic and aesthetic management intended to limit the functional and aesthetic consequences of the loss of teeth related to this periodontal disease. This paper provides the first demonstration of a link between a diagnosis and a therapy on an identified individual using new digital technologies used in modern dentistry. We propose that the objective of the treatment was triple: therapeutic, aesthetic and societal. Beyond the only therapeutic care and far from the only coquetry, this study shows also the importance of the appearance for aristocratic women submitted to strong social constraints (like stress or widowhood), the speech of the disfigured women being could be regarded as depraved.
