Saliva contains many defense factors and plays a key role in oral metabolism. Salivary calcium, due to its affinity to be readily taken up by plaque, is an important factor not only with regard to the onset of periodontitis but also significantly with regard to dental health. The aim of this study was to estimate the salivary concentration of calcium, in a group of adults undergoing active orthodontic treatment. The levels of salivary calcium were determined at the beginning, and after 16 weeks of active orthodontic treatment. A total of 40 healthy individuals with a mean age of 23.9 years were enrolled in the study group, while 40 subjects served as controls. Two milliliters of saliva were collected from all participants, and salivary calcium levels were measured by biochemical assay. Mean salivary calcium levels were significantly higher in subjects after 16 weeks as compared to subjects at the beginning of orthodontic treatment and to the control group (p= 0.001). A significant association between higher salivary calcium levels and orthodontic treatment has been established, therefore, monitoring salivary calcium levels might be a useful tool to establish periodontal health status during active orthodontic treatment along with other inflammatory parameters.
