Abstract
This study was carried out to investigate the relation between salivary levels of calcium, phosphorous and alkaline phosphatase activity and dental caries experience in three groups of patients. A total of 75 Egyptian children were included in this study (group I :25 children with severe dental caries, group II: 25 children with moderate dental caries and group III: 25 caries free children), their ages ranged from 6 to 13 years old. Children were selected from those reported to the out patient dental clinic of the pediatric dentistry and orthodontic departments of the Faculty of oral and dental medicine, Cairo university. Children were examined clinically by the same examiner for dental caries experience which was recorded by the DMF for the permanent dentition and def for deciduous dentition, using sterile mirror and probe for each child. Unstimulated saliva (3ml) was collected from each child in sterile falcon tube one week after oral prophylaxis and transfered to biochemistry laboratory Faculty of medicine, Cairo university to estimate the levels of salivary calcium, phosphorus and alkaline phosphatase activity in the three study groups. Calcium and phosphorous concentration in saliva was estimated by colorimetric method while alkaline phosphatase activity was estimated by kinetic method using spectrophotometer. Data collected were tabulated and statistically analyzed to evaluate the correlation between salivary levels of calcium, phosphorus and alkaline phosphatase activity and dental caries experience in the three study groups
