Concentration of Some Minerals in Whole Saliva from Patients with Adult Periodontitis / 中国医科大学学报

ABSTRACT

Objective: Our aim was to analyze the relationship between the concentration of some minerals in saliva and periodontitis.Methods:Twenty-five patients with adult periodontitis (AP group), 25 age and sex matched healthy people(N group) were selected. Unstimulated whole saliva samples were collected and qualified for the concentration of TCa,P,Mg2+, Na+,K+, and Cl-.　Clinical parameters on periodontitis were also assessed for the patients. All the aforementioned indices were measured repeatedly at the end of the fourth week after initial therapy. Results:The clinical condition of the patients improved significantly after treatment. The level of saliva Ca elevated before and after treatment in AP group than that in N group. Before treatment, the concentration of Na+ also increased significantly, but it decreased to normal level after initial therapy. The findings also indicated the positive relationship between the concentration of salivary Na+ and pocket probing depth as well as gingival index before treatment.Conclusion:The elevated level of saliva Ca is a sign of periodontitis and may help the occurrence and progress of periodontitis. The level of saliva Na+ may indicate the pocket depth and degree of gingivitis.The saliva Na＋ is closely associated with the clinical condition of periodontitis.
