Calcium and other salivary factors in periodontitis-affected subjects prior to treatment
The aim of the research was to study mineralization-related variables of saliva, calcium in particular, in periodontitis-affected subjects before periodontal treatment. The test group consisted of 20 periodontitis-affected patients; the control group, 15 subjects free from periodontitis. The saliva was collected to calcium and phosphate concentration. Salivary calcium level was shown to be higher in treated periodontitis-affected subjects (P+) than in periodontitis-free patients (P-). In conclusion, high calcium concentration of saliva is characteristic of P+ patients before and after periodontal treatment [S.L.]
