Abstract

|
|
The author measured the degree of alveolar bone resorption around mandibular central incisors in Korean females (254).
Mandibular central incisors were selected from the females who do not have periodontal disease or malocclusion.
The selected radiograms were enlarged in the 5" x 7" printing papers for the precise measuring. The obtained results were as follows;
1. The average alveolar bone resorption around mandibular central incisors in Korean women were 1.91mm in 3rd decade, 2.16mm in 4th decade, 2.51mm in 5th decade, 2.70mm in 6th decade, 2.94mm in older age group.
2. Alveolar bone resorption and age were in positive correlation; there is a tendency that the alveolar bone resorption increase with aging.
3. The regression equation is as follows.
Y = 13.25x + 7.06 (r = 0.60, n = 254)
(Y =estimated age, x = Length (C-E Jun Lion-alveolar crest)
