Alveolar bone resorption in the skulls.
In this report the quantitative relationship between the alveolar bone and cervical part of the teeth in millenary intervals of human existence is reported. In this study 115 skulls were examined of which 27 belonged to the 1st, 22 to the 10th and 66 to the 20th century. The skulls belonged to persons of both sexes older than 20 years. Each group mentioned was divided into four subgroups according to the age persons (20-29, 30-39, 40-49, 50+). It measured tooth-cervical-height index (TCH-index) according to Davies and coll. The resorptive changes on the alveoli are increasing in the older age, the alveolar resorption is greater on the vestibular than interdental side, the higher values of alveolar resorption in the skulls of the 20th century are statistically significant in relation to the skulls from the 1st and 10th century.
