Nyvad Criteria for Assessment of Caries Lesion Activity and Severity

  • Vita MachiulskieneEmail author


The diagnostic criteria for the assessment of caries lesion activity and severity were developed by Nyvad and coworkers based on the evidence that the clinical status of the caries lesions can change in response to the oral environment. The Nyvad criteria reflect the visual-tactile surface characteristics of the caries lesions such as integrity, texture, translucency/opacity, lesion location, and surface color. The classification of caries lesions incorporates scores for active/progressing and inactive/arrested lesions at two levels of severity, non-cavitated and cavitated. The Nyvad criteria have been tested in clinical trials and proven to be reliable and valid. Clinical differentiation of the detected lesions according to their stage of activity allows dental professionals to identify lesions that are in need of treatment, to choose the appropriate management strategy, and to monitor the course of the disease.
