Abstract

Zinc (Zn) is a mineral contained in the enzyme, alkaline phosphatase, present in gingival crevicular fluid. It is believed that a relationship exists between gingival crevicular fluid volume and gingivitis. Gingivitis in children is caused by the accumulation of plaque and bacteria. Plaque is a layer on the surface of teeth containing bacteria. Streptococcus mutans is most commonly found on plaque and colonizes on teeth surfaces. This research was conducted to determine the relationship between Zn levels in gingival crevicular fluid, and gingivitis and the growth of S. mutans colonies in children. The subjects were 30 children, aged 12-14 years. Zn levels were measured using the atomic absorption spectrophotometry method. A weak but positive correlation was established between Zn levels in gingival crevicular fluid and gingivitis (p < 0.050). This finding was not statistically significant. Higher Zn levels in gingival crevicular fluid were equated with increased gingivitis in children. By contrast, a negative and moderate correlation, which did not reach statistical significance, was established between Zn levels and the growth of S. mutans colonies in children (p = < 0.050). Higher gingival crevicular fluid Zn levels were equated with decreased colony growth of S. mutans in children.
