A cross sectional study conducted among institutionalized VI and NVI adolescents in Lagos State, Nigeria. One hundred and thirty-two randomly selected VI adolescents aged between 9 and 23 years and 138 NVI participants aged between 9 and 17 years were recruited using a multi-stage random sampling technique.

More of the NVI participants had good oral hygiene status (29.0%). Uncomplicated dental injury was more prevalent among the VI male participants than their NVI counterparts while malocclusion was significantly less among the NVI participants.
