Randomly sampled out 157 extracted Korean adult teeth, aged 12 to 79 years, was applicated to estimate the age by Gustafson´s method, were evaluated and analyzed in terms of physiological aging changes.
The results are as follows.
1. It was reconfirmed that there existed comparatively close correlationship between age and
score, especially in old age.
2. Korean score had comparatively high level than those of European.
3. In the probability of age edetermination, the estimation error was the most high level in the age of 70"´ with x.47, and next order was in the age of 10 19 with ±5.20, 60"´ 69 with ±5.8,30 ´v 39 with ±5.98, 50 "´ 59 ± 6.20, 40 ´ 49 with ± 6.72,20 29 with ± 9.28. Mean value was ± 8.03.
4. The regression equation is as follows.
y = 355 x +8.52 (r = 8.75) standard deviation o = ± 8.03 (y = estimated age x = score)
5. In age determination with those data, needs to estimate slightly lower than calculated age in age range of 10 ^ 49, and higher in 50 ^´70 for the real age determination.
