Information in this article was made available from a guide for parents and dental providers of children with special needs developed by the Oklahoma Dental Foundation in partnership with several funders.  The entire guide is available for download at: Oral Health Care For Children With Special Health Care Needs.

The following is an excerpt from page 16 of the guide.

Chromosomal conditions such as Down syndrome are lifelong genetic conditions that range in complexity and severity. Children may have underlying medical conditions and a consultation with their primary physician may be needed before beginning dental treatment. Typical symptoms of Down and other genetic syndromes fall into many categories. This section intends to cover only those issues that are unique to these disorders. Other conditions and/or behaviors will be covered in other sections of this guide and the resource section.
