AIM: The aim of this study was to provide basic representative data on the prevalence of @entity3232 involving @entity3626 in both primary and early mixed dentition and to examine the relationship between these @entity3232 and @entity409 . The results should be viewed from an orthodontic prevention and early treatment perspective. SUBJECTS AND METHODS: Orthodontic findings in the maxilla and mandible as well as the myofunctional status of 766 @entity1 in primary dentition and 2,209 @entity1 in mixed dentition were examined clinically in a cross-sectional study. The following parameters from each jaw were subjected to orthodontic analysis: crowding in the anterior and posterior regions of the maxilla and mandible in primary and mixed dentitions, deviations from normal maxillary arch forms in the primary dentition, deviations from normal anterior maxillary arch width in mixed dentition and maxillary apical base morphology in mixed dentition. Static and dynamic @entity409 were documented with reference to specific parameters and clinical tests. RESULTS: Crowding was observed in every tenth @entity1 in primary dentition (10.8%) and in every second @entity1 in mixed dentition (49.7%). @entity2133 posture, visceral swallowing, @entity7687 and oral habits were statistically significantly more frequent in @entity1 in primary dentition presenting a narrow maxillary arch. Reduced anterior maxillary arch width (compression) was statistically more frequent in @entity1 in early mixed dentitions with @entity2133 posture. A narrow maxillary apical base correlated positively with all the @entity409 analyzed. CONCLUSIONS: Deviations from a regular arch form become apparent very early during dentition development and coexist with specific @entity409 . They are thus important indicators for the early detection of functional abnormalities, causing deviations from normal dentition development. In @entity1 with @entity409 the development of a narrow maxillary dental arch should be prevented by myofunctional therapy and by educating the parents. Interceptive orthodontic measures to treat a narrow maxillary arch in primary and early mixed dentition should also focus on eliminating functional disturbing factors, such as @entity409 . Interdisciplinary cooperation with specialists in other fields of medicine, e.g. otorhinolaryngology and speech therapy, is essential to achieve this goal.
