  • Title: Biochemical indicators of dental caries in saliva: an in vivo study.
    Author: Hegde MN, Hegde ND, Ashok A, Shetty S.
    Journal: Caries Res; 2014; 48(2):170-3. PubMed ID: 24504381.
    Abstract:
    This study evaluated the superoxide dismutase (SOD) activity, copper and zinc levels in saliva of caries-active and caries-free individuals. Eighty healthy adults were divided according to WHO criteria: caries-free (DMFT = 0) and caries-active (DMFT >10). Saliva collected was estimated for SOD activity as well as copper and zinc levels using the atomic nitro blue tetrazolium chloride reduction method and absorption spectrophotometry, respectively. The Student t test was applied. In conclusion, SOD activity as well as copper and zinc levels increased in the caries-active group and showed statistically significant results.
