In Yemen, there is no information available regarding
oral health status of children with DS. such information would enable pediatric dentists to plan
and provide appropriate preventive protocol as well as
effective treatment for these underprivileged children.
Therefore, this study was planned and conducted to
assess the oral hygiene and gingival health status of
children with DS attending special needs schools in
Sana’a, and also to determine the association between
these outcomes and socio‑demographic and clinical
variables.
