Abstract
|
|
|
This thesis was to investigate sex difference by employing the methods of Bernadskij´s and it´s modification by means of the evaluation of Ph of dentin in 162 extracted teeth. The obtained were as follows:
1. In 72% of all experiments, Ph of human dentin substance was higher in female than in male.
Mean Ph was 13.175:t 0.031 in male and 13.245 ± 0.030 in female.
2. After comparative studies on each Ph in anatomical region of tooth arrangement, the sex
difference of Ph was most obviously showed in molars.
3. In Ph change according to ages, the 30´s was the highest in male and the 20´s in female, also
Ph showed decreasing tendency by the increasing of age in both male and female.
4. These was no Ph difference in anatomical regions of tooth arrangement.
5. Mean Ph was 13.282 ± 0.013 in under 50 years of age and 13.182 ± 0.022 over 50. It proved
that Ph was higher in under 50 years of age than in over 50.
