The aim of this study was to clarify the recognition of the parents concerning the malocclusion of their own children in Hellman's 2A stage dentition. We investigated the denture/occlusion in children and the recognition of their parents concerning the malocclusion of their own children. Questionnaires on their denture/occlusion were given to their parents. The following results were obtained.
1. The percentage of children were diagnosed with malocclusion was 64.5%.
2. The ratio of parents worrying about the malocclusion of the child amounted to 32.3%, and the most frequent type of malocclusion causing parents to worry was extreme maxillary overjet and anterior open bite. Anterior malocclusion was comparatively easy for parents to recognize.
3. The parents were concerned about the expenses and the time the treatment would take.
4. The rate of concordance of a dentist and a guardian concerning malocclusion was low.
