As part of a broader study of the restorative care index of 5- and 6-year-olds and 11- and 12-year-olds, a sample study was carried out among 1,361 dentists, who were surveyed by means of a web-questionnaire concerning this issue. In total 447 dentists (33%) filled in the questionnaire completely. Concerning the development of dental care of children, opinions differed widely: 46% of those questioned spoke of an increase in the incidence of caries during the past 5 years and 44% reported no change. Furthermore, dentists hold different views on the treatment of the primary dentition. There was no consensus of opinion about the necessity of treating caries in young children and there was a comparable lack of agreement about how and when treatment should be given. The majority of dentists express a need for support in their practice (possibilities for referral, protocols, informational material) concerning routine oral examination, the preventive and/or curative treatment of (young) children.
