The<unk>  is a widely used diagnostic medical tool designed to produce a clinical oral dryness score (CODS) which quantifies the extent of dryness of the mouth, with the aim of making a decision of whether to treat or not, and to monitor its progression or regression. It can be used to assess salivary flow and therefore calculate a risk of dental caries. In addition, it has a particular use in the assessment of dry mouth in Sjögren syndrome. Based on a 10-point scale of clinical physical findings, a score of one is least severe and ten most severe.
