[A global approach to the dental care of children and young adults with trisomy 21. II. The planning of the preventive and interceptive care of Down's syndrome patients].

In this second part, the principles and modalities of a personal contribution to the realisation of a specific protocol that uses preventive and interceptive criteria to plan odontostomatological treatment in patients with Down's syndrome are presented. A special type of treatment is proposed. This is distinguished chronologically into five stages with periodic visits to specialist hospital structures, implying the start of treatment in Down's children at the age of 2-3 months and programmed continuation of such treatment right up to the age of at least 18 years.
