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 rep orted. In this study 115 skulls were examined of which 27 belonged to the 1 st, 22 to the 10th and 66 to the 20th century. The skulls belonged to perso ns 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 c ell. The resorptive changes on the alveoli are increasing in the older age, the alveolar resorption is greater on the vestibular than intel dental sid e, the higher values of alveolar resorption in the skulls of the 20th centu ry are statistically significant in relation to the skulls from the 1st and 20th century.
