The effect of environmental stress on mitochondrial energy supply of myelinic and nonmyelinal nerve fibers of the tooth pulp during development

The aim of the study was to assess the quantitative representation of mitochondria in the nerve fibers of tooth pulp tissues in children born and living in prosperous and environmentally unfavorable areas. The influence of environmental stress on the energy supply of the permanent tooth tissue was revealed. The epidemiological study included children from 8 settlements of Udmurtia, born and living in safe and ecologically unfavorable areas. The surveyed children were divided into 5 age groups (according to the WHO classification): first childhood, second childhood, adolescence (5-6 years; 7-8 years; 9-10 years; 11-12 years; 13-14 years).
