Comparison of two methods for measuring salivary mineras: calcium, magnesium and phosphate
Introduction: The concentration of minerals in the saliva as calcium, magnesium and phosphate reflects many functions of saliva: remineralisation processes, buffering ability, oral microbiota and periodontal bone metabolism. Salivary minerals measurement is increasing in dental experimental and clinical research. The aim of this study was to evaluate two different laboratory methods for estimation of salivary calcium, magnesium and phosphate concentration. Materials and methods: Unstimulated salivary samples were obtained from healthy subjects (N=23). Concentration of salivary minerals Mg, Ca and P were measured by two methods: standard spectrophotometry method and high-pressure microwave assisted inductively coupled plasma mass spectrometry (ICP-MS) method. Data were compared and tested for the strength of a relation between two groups of variables for each salivary mineral. Results: Concentration of salivary Mg and salivary P measured by standard spectrophotometry was significantly correlated to concentration measured by microwave assisted ICP-MS method, Mg (r=0.64, p<0.05), P (r=0.61, p<0.05). Concentration of salivary Ca measured by standard spectrophotometry was not correlated to concentration measured by microwave assisted ICP-MS method. Conclusions: Standard spectrophotometry and microwave assisted inductively coupled plasma mass spectrometry are consistent for measuring salivary magnesium and phosphate but not for salivary calcium. Because salivary minerals measurement is increasing in popularity, it is important to be aware of the different results generated by these two methods for salivary calcium.
