Intellectual Disabilities (ID), involves impairment of cognition and adaptive/functional skills. There are three criteria that must be present for diagnosis of ID: Intellectual functioning deficit, significant limitations in adaptive functioning and evidence that the limitations became apparent during the developmental period. ID patients comprise 2-3% of the general population. Some studies show that people with ID have worse oral hygiene, increased tooth decay and also a worse periodontal condition than the general population. The techniques that allow the management and clinical dental treatment of patients with ID are: behavioral management, which is more used in patients with mild or Moderate ID in which a minimum degree of communication can be established. The physical restriction is used in any degree of ID that requires it to avoid injuries during dental treatment. Sedation is used in patients with Severe ID unable to cooperate and finally general anesthesia, which should be used when all the previous techniques have failed, either in the case of a long and complex treatment or in patients with Profound ID. As a result presents the alternatives to the professional can address individually patient, taking into account the degree of ID, thus able to improve their quality of life.
