  • Title: Orofacial regulation therapy in children with Down syndrome, using the methods and appliances of Castillo-Morales.
    Author: Hoyer H, Limbrock GJ.
    Journal: ASDC J Dent Child; 1990; 57(6):442-4. PubMed ID: 2147926.
    Abstract:
    The varying hypotonia in Down syndrome is one of its most dramatic signs. In particular, the facial expression and oral dysfunctions of these handicapped persons are uniquely characteristic. The more-or-less permanently open mouth; the prolapse of the tongue, exposed on the everted lower lip; and a lack of mastication, deglutition and speech are primarily caused by the hypotonic orofacial muscles. Breathing through the mouth leads to a dehydration of bacteria and plaque on gums and teeth, and ultimately to premature destruction of the dentition. This developmental syndrome indicates the need for early functional training of the orofacial muscles. Oral Regulation Therapy as described by Castillo-Morales was applied to seventy-four children here, with encouraging results.
