Craniofacial parameters during growth from the deciduous to permanent dentition--a longitudinal study.

Data on the dynamics of craniofacial growth, obtained by simple non-invasive measurements, are scarce in comparison with those collected by cephalometric methods. The aim of this study was to measure a number of craniofacial parameters, and to evaluate their changes during transition from the deciduous to the permanent dentition. A sample of 61 subjects (32 boys and 29 girls) were followed longitudinally by annual examination from an initial mean age of 4.

Morphological cephalometric differences between two European populations.

Earlier research in craniofacial morphology of the inhabitants of Mainz (Germany) and Zagreb (Croatia), who represent the populations of wider areas, have shown some roentgen-cephalometric differences. The aim of this study is to determine the craniofacial morphologic differences of these populations in three dimensions. The sample consists of 200 adult examinees, male and female respectively, inhabiting the mentioned areas.

[Secular trend as a factor of craniofacial morphological changes].

The study was carried out in two age-matched groups of patients from two different periods of time. The aim of the study was to determine whether any craniofacial system alterations attributable to the influence of secular trend had occurred during a defined period of time. Four basic craniofacial variables, from which the craniofacial indices were derived, were measured.

[Growth dynamics of the four main craniofacial dimensions in relation to orthodontic finding--a longitudinal study].

Analysis of growth dynamics of the four main craniofacial dimensions at the transition point from primary into mixed dentition was performed in order to better determine the effect of individual orthodontic anomalies starting to manifest at that time, on the direction and extent of the alterations observed. A sample consisting of 73 children aged 3.5-5.

[The changes of the occlusal relationship from deciduous to the permanent dentition in the longitudinal sample].

The examination of the dynamics of the changes in sagittal, vertical and transversal occlusal relationship has been carried out on the sample of the 66 examinees of the both sexes. The children were examined for the first time at the age of 3.7 years, the again three times repeatedly (within a year) during the first period of the change of teeth.
