[A contribution to anomalous number of teeth in children in the Zilina District].
The authors investigated the frequency of unfounded teeth in a selected cohort of jaw-orthopedic patients from the iZlina district at the age of seven to 12 years. From the total of 4,405 patients, a decreased number of teeth was found in 179 children (4%), 130 of them being girls and 69 boys. In all the 179 children, 410 teeth missing. Three teeth were missing per one child on the average. Patients with cleft disorders and evident displasiae were excluded from the investigation. The third molars were not considered in the evaluation. Most of the affected children live in localities where they are exposed to air pollution. These patients displayed various aplasiae of tooth groups, where event constant tooth groups (ocular teeth) were not exceptional. Recent data from the world literature present various patterns of partial anodontia as a result of numerous genetic-mutational interreactions of living environment.
