[The comparative characteristics of the morphological indices of the maxillodental system in 7- to 12-year-old children with absent closure of the dental arches in the frontal plane].
The height of permanent teeth crowns was measured and the status of supporting tissue studied with the use of a Periotest apparatus (Siemens, Germany) in 95 children aged 7-12 with physiologic dental occlusion and in 70 age-matched children without dental occlusion in the frontal section. The data obtained by this apparatus permit a judgement on exercise tolerance of periodontal tissue. The size of the vertical fissure between maxillary and mandibular anterior teeth was measured in the children with abnormal occlusion and analysis of correlations and regressions of this parameter with the height of permanent teeth crown was carried out. The findings evidence that dental supporting tissue strength changes with age, as the maxillodental system develops, and that this characteristic is rather low in the children with non-occluding frontal teeth.
