Salivary calcium was shown to be higher in treated periodontitis-affected subjects (P+) than in periodontitis-free patients (P-). Here the aim was to study whether differences in calcium or other salivary factors exist prior to treatment. The test group consisted of 20 (15 men, 5 women) periodontitis-affected subjects and the control group 15 subjects (10 men, 5 women) free from periodontitis. Paraffin-stimulated whole saliva was collected to determine the flow-rate, calcium and phosphate concentrations, pH, buffering capacity, numbers of mutans streptococci, lactobacilli and yeasts. The results showed a higher calcium concentration (p < 0.05) in the P+ group (mean: 1.68 mmol/l; SE: 0.06 in men and mean: 1.49 mmol/l; SE: 0.10 in women) than in the P-group (mean: 1.48 mmol/l; SE: 0.09 in men and mean: 1.18 mmol/l; SE: 0.10 in women). The P+ group had more intact teeth (mean +/- SE: 9.9 +/- 0.8 in men and 11.2 +/- 2.0 in women) than the P-group (mean +/- SE: 8.3 +/- 0.7 in men and 8.2 +/- 2.4 in women). The present findings may indicate that an elevated level of salivary Ca is characteristic of P+ patients both before and after periodontal treatment.
结果显示，接受治疗的牙周炎患者（P+）唾液中的钙含量高于无牙周炎的患者（P-）。本研究旨在探讨治疗前钙或其他唾液因子是否存在差异。试验组由20名（15名男性，5名女性）患有牙周炎的受试者组成，对照组有15名（10名男性，5名女性）无牙周炎的受试者。收集石蜡刺激后的全唾液，以测定流速、钙和磷酸盐浓度、pH值、缓冲能力、变形链球菌、乳酸杆菌和酵母菌数量。结果显示，P+组（男性平均：1.68 mmol/l；标准误：0.06；女性平均：1.49 mmol/l；标准误：0.10）的钙浓度高于P-组（男性平均：1.48 mmol/l；标准误：0.09；女性平均：1.18 mmol/l；标准误：0.10）（p < 0.05）。P+组（男性平均±标准误：9.9±0.8；女性平均：11.2±2.0）比P-组（男性平均±标准误：8.3±0.7；女性平均：8.2±2.4）拥有更多的完整牙齿。目前的研究结果可能表明，唾液钙水平升高是P+患者在牙周治疗前后的特征。
