Masticatory dysfunction in persons with Down's syndrome. Part 1: aetiology and incidence.
The functional and anatomical characteristics of Down's syndrome have direct repercussions on oral health. Orofacial dysfunction is on account of poor neuromotor control, muscle weakness, dental anomalies, dysmorphology and intercurrent illness. In particular, feeding and swallowing are impaired. The aim of this first article was to summarize the orofacial difficulties encountered by persons with Down's syndrome at all stages of life and to explain their aetiology. Indicators are proposed for the identification of masticatory problems within this population and reduced masticatory efficiency is discussed in relation to repercussions on oral and general health and on the social integration of persons with Down's syndrome. A second article will describe techniques for preventing, treating and compensating for masticatory dysfunction in this population.
