Tongue posture importantly influeces development of teeth and jaws. The clinical assessment is unreliable because of the anatomical limitations. In the study we for the first time used a 3D ultrasonography to make referential 3D reconstructions of the tongue dorsum with known posture. Referential reconstructions were used for the objective assessment of the tongue posture in children with unilateral posterior crossbite and in children with no malocclusions in the period of deciduous and early mixed dentition. Significant differences in the tongue posture have been found.

Amelogenesis imperfecta (AI) is an inherited disorder with alterations in the quality and/or quantity of the dental enamel, with widely varying phenotypes and genotypes. On the other hand, there are reports that AI enamel alteration can be accompanied by craniofacial characteristics e.g. open bite (OB), taurodontism, a syndrome or systemic diseases. In this research we found that all patients with rough hypoplastic AI had a moderate to severe malocclusion with increased vertical dimensions regardless of the presence or absence of the ENAM g.8344delG mutation.

The knowledge of the arrangement of hydroxyapatit (HA) crystals is important to understand the mechanical properties of dentin and progression of dental caries. By newly developed simulation of EPR spectra, experimental and calculated spectra were compared and the dentin structure was characterized in terms of arrangement of HA crystals and dentinal tubules. Arranged HA crystals form intratubular dentin and with their longer axis perpendicular to the axis of dentinal tubules are oriented, around which they are radially orientated.

Nitric oxide synthase (NOS) inhibitors are reported to protect against the local tissue damage in gingivitis and periodontal disease by reducing nitroxidative stress during inflammation. These inhibitors systemic effects were investigated in a murine chronic oral inoculation with Porphyromonas gingivalis. The systemic use of selective iNOS inhibitor 1400W or non-selective NOS inhibitor L-NAME differently affects systemic NO formation in mice.

The aim was to compare sagittal facial growth in children with unilateral cleft lip and palate treated with different surgical protocols but similar presurgical orthopaedics at 10 years. There was considerably normal sagittal facial growth in centre 1, with tendency of forward growth of the mandible. In centre 2 there was a slight decrease in sagittal maxillary and mandibular growth with unchanged intergnathic relation. There was no statistically significant difference in sagittal growth between the centres, both of them differ from noncleft control group.
