Salivary Calcium, Phosphate and Fluoride in Dental Caries.
J Ayub Med Coll Abottabad Jan ;12(4):3-5.

Background: This study evaluated the protective role of some salivary factors like pH and adequate level of calcium, phosphate and fluoride in dental caries. Methods: A total of 100 subjects of either sex aged 10-40 were selected. Decayed, mussed and filled teeth (DMFT) were used as indices for scoring the dental caries and were distributed in to 4 groups on DMFT indexes as 4-8, 9-16, 17-24 and more than 25 respectively, while the control subjects had DMFT index equal to or less than 3. Saliva was collected and pH, calcium, phosphate, fluoride and lactic acid were analysed. Results: Patients of dental caries showed significantly decreased pH, phosphate, fluoride (p<0.001) and a significantly increased value of lactic acid (p<0.001) in group Il, 111 and IV when compared to control. While in group I significantly decreased level of calcium (p<0,05) and increased level of lactic acid (p<0.001) were observed. Among groups prominent significant changes were observed in group IV.
