RESUMO
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.
