The people with disabilities living in residential facilities have more difficulty in caring oral hygiene than those living at home.

Patients classified according to types of disability. Mental retardation were 75.3%, mental disorder were 6.0%, crippled disorder were 7.4%, brain disorder were 6.5%, visual disorder were1.4%, auditory and speech disorder were 2.3% and autism disorder were 0.9%. Performed treatments were 99 scaling and curettage, 88 fluoride varnish and TBI, 4 extraction, 1 endodontic treatment, 16 caries control (resin filling, GI filling), 1 denture repair and 8 refuse the treatment.
