[Age- and sex-specific tooth and jaw measurements and their relation in the 1st mixed dentition phase--a longitudinal study on Jena children at the age of 7 1/2 to 8 1/2 years].

Abstract

In a longitudinal study consisting of three single examinations dental findings of 89 individuals (40 boys and 49 girls) were recorded. The aim of the study was to check up the process of dental growth and development of 7.6- to 8.6-year-old children. Age- and sex-specific differences could be established in the three occlusal dimensions by means of clinical findings and 3-d-analysis of the plaster casts. The rate of DMF teeth was remarkably low in girls and boys; the presence of malocclusions was surprisingly high.
