[Anomalies of deciduous teeth and findings in permanent dentition].
Prevalence of anomalies of deciduous teeth has been analyzed in the general population of Zagreb preschool children. The sample comprised 2,987 children from 3 to 6 years of age (1,582 boys and 1,405 girls). Hypodontia was found in 0.47%, hyperdontia in 0.10%, and double teeth in 0.43% of total sample. Total prevalence of all anomalies in the sample was 1.0%. The sample for the analysis of perm...
متن کاملComparison Between Deciduous And Permanent Teeth in Relation to their Utility for EPR Dosimetry Comparison Between Deciduous And Permanent Teeth in Relation to their Utility for EPR Dosimetry
Introduction Ionizing radiation generates extremly long lived CO2 radicals in calcified tissue. The CO2 concentration rises linearly with dose and can be detected directly by means of EPR spectroscopy (electron paramagnetic resonanc). For retrospective dose estimation tooth enamel and dentine as well as bone samples may be used as in-vivo-dosimeter. Enamel analysis of permanent teeth has been e...

متن کاملIdentification of significantly different modules between permanent and deciduous teeth by network and pathway analyses.
The differences in genetic backgrounds between deciduous and permanent teeth might contribute to the differences in developmental processes, histological characteristics, and tooth life cycles. Here, we attempted to identify significantly different modules between permanent and deciduous teeth via network and pathway analyses. We identified 291 differentially expressed genes (DEGs) between perm...
