THE CHLORIDE LEVEL OF SALIVA. II
JOHN T. ANDERS 1
1 Biochemistry Laboratory, Forsyth Dental Infirmary for Children, Boston, Mass.
For 3 series of children, spread over 18 months, the chloride level of the saliva was tested, and it was established that there is a constant significant relationship between that level and the degree of caries activity. The higher the level of a child's salivary chloride, the greater is the tendency for dental decay activity. The mean average for these children was established at 16.25 ± 4.63 meq. per liter with a range of 6.49 to 42.87 meq. per liter. It was found that replicability was at about the 80 per cent level for 2 out of 3 tests conducted at 6-month intervals.
