The contents of citric acid, calcium and phosphorus in the alveolar bone of the periodontal patients and clinically healthy subjects were studied, and compared with various clinical findings.
The following results were obtained:
1) The citric acid contents in the alveolar bone were slightly higher in the periodontal patients than in clinically healthy subjects (p>0.05).
2) The calcium contents in the alveolar bone showed remarkably higher value in the periodontal patients than in clinically healthy subjects (p<0.05).
3) The phosphorus contents were slightly lower in the periodontal patients than in clinically healthy subjects (p>0.05).
4) Statistically significant correlations were not found between the alveolar bone loss and contents of citric acid, calcium and phosphorus.
