Abstract:
Objective:To determine the concentration of three major salivary histadine-rich proteins(HRPs),HRP-1,HRP-3 and HRP-5 in whole saliva of children and to examine the association between HRP-1,HRP-3,HRP-5,total HRPs and caries status. Methods: paraffin-wax stimulated and non-stimulated whole saliva was collected from each of 42 children aged 3-5 years, coming from the same kindergarden. HRP-1,HRP-3,HRP-5 concentrations in saliva were determined with a high-performance liquid chromatography. The total HRPs concentration was calculated and the relationship between HRP-1,HRP-3,HRP-5,total HRPs and caries status was analyzed. Results: (1) The mean concentrations(?g/ml) of HRP-1,HRP-3,HRP-5 and total HRPs in non-stimulated whole saliva were 8.56?3.42, (13.91)?6.59,7.35?3.23 and 29.65?8.69 respectively,those in stimulated saliva were 10.85?3.71,15.92?(5.94),7.68?3.28 and 34.69?9.41 respectively.The concentrations of HRP-1, HRP-3 and total HRPs in stimulated saliva were significantly higher than that of non-stimulated (P
