Summary: Children with impaired hearing are entitled to more time in the dental surgery than healthy children. The objective of the work was to provide complete preventive care regardless of the child’s affection.The authors investigated children in the Institute for children with hearing disorders. The group was divided into two subgroups S1 (born in 1990–1995) and those born in 1985–1989) and a control group of healthy subjects divided similarly. In both groups the caries rate was evaluated by the DMF index and the index of oral hygiene by the P1I index. The mean caries rate in the younger children of the investigated and control group was almost identical, in the older children it was significantly higher in the affected children. The increment of new caries was after introduction of the preventive programme lower than in the equally long period before the investigation. In the younger children the number of caries declined on average from 0.5 to 0.23, in the older ones from 0.82 to 0.63. The P1I values declined steadily during every examination and the older children achieved a significant improvement. Their resultant plaque index had a mean value of 0.32 and in the control group 0.65. The paper evaluated the preventive programme of oral health provided to children with impaired hearing where the main emphasis was on training of a correct technique of tooth brushing. If communication is established the patient is no longer handicapped in the dental surgery.
