This third edition of the Application of the International Classification of Diseases to Dentistry and Stomatology (ICD-DA) provides a coherent system for coding and classifying data on oral and dental disorders, particularly when electronic or mechanical means of retrieval and analysis are used. Scope of the classification includes all diseases and conditions that occur in, have manifestations in, or are associated with the oral cavity and adjacent structures. ICD-DA is derived from the Tenth Revision of the International Classification of Diseases (ICD-10) and should be used in conjunction with this parent work.
