Serum Calcium, Phosphate, Fluoride and Lactic Acid in Dental Caries

Abstract

This study was carried out to evaluate the possible protective role of some serum factors like pH and adequate level of calcium, phosphate and fluoride in dental caries. Total of 100 subjects of either sex, aged 10-40 were selected. Decayed, missed and filled teeth (DMFT) were used as indices for scoring the dental caries and were distributed into 4 groups on the basis of DMFT indices as 4-8 (Group I), 9-16 (Group II), 17-24 (Group III) and more than 25 (Group IV), while the control subjects had DMFT index equal to or less than 3. Serum was collected and pH, calcium, phosphate, fluoride and lactic acid were analyzed. Patients of dental caries showed significantly decreased levels of calcium, phosphate, fluoride (P
