Most dentists find it important to treat the dentition of children; nevertheless cavities often remain untreated. In order to gain insight into the treatability of children, a survey was carried out involving 4,500 dentists of a health insurance company. A representative group answered questions about the necessity of treatment, and treatability of children and about the possibility of referring children to a colleague or a paediatric dentist. According to the questionnaire dentists find it important to treat the dentition of children. Most problems during dental treatment occur in the 0-6 years age group. Dentists are more likely to refer children in this age group to a colleague or pediatric dentist for treatment.
