Abstract
Background: Mixed dentition period is characterized by expressed dynamic. Radial methods of the examination let
follow regularities of the age dynamic of the structure and density of the hard tissues of the dentomandibular apparatus
while mixed dentition. The aim of the investigation – temporary and permanent teeth hard tissues and osseous tissues of
the jaws density determination in the period of mixed dentition and establishment of their age dynamics.
Material and methods: 30 radiovisiograms of 5-13 year old children, without any pathology in anamnesis which could influence on the mineralized tissues condition were analysed. All of the examined were devided into 3 age groups- 5-6
years, 7-9 years and 10-13 years. The examination was made on dental radiovisiograph SIEMENS with softwear TROPHY
RADIOLOGY.
Results: osseous tissue density of the jaws has a tendency to decrease during all examination period. Middle density of the temporary teeth hard tissues decreases in every next age group which is connected with root density decrease.
Permanent teeth bud density indexes have an expressed tendency to increasement. Permanent teeth hard tissues density
decrease in 7-9 year olds and increases significantly in 10-13 year old children. Temporary and permanent teeth crowns
density is significantly higher than in roots.
Conclusions: examined structures density age dynamic is significant during period of mixed dentition but different
and individual for each separate object of the investigation. Received data can become a morphological basis for working
out new methods of early diagnostic and dentomandibular anomalies corrections.
