Black dental stain is a discoloration of the teeth, which appears as a black-pigmented line or collection of black dots on the cervical third of the tooth crown. Tooth plaque with black dental stain contains higher calcium and phosphate concentrations compared to tooth plaque without black dental stain. The calcium and phosphate composition of saliva is suspected to be the cause of calcium and phosphate level elevation in black stained dental plaque. This study aimed to determine the difference in calcium and phosphate levels of saliva from children with black dental stain and without black dental stain. The subjects were children aged 4-8 years, and as many as 30 children, consisting of 15 children with black dental stain and 15 children without black dental stain, were included in the study. The samples of calcium and phosphate were obtained from the children's saliva. The levels of calcium and phosphate were measured using a UV-Vis spectrophotometer. The results showed, that the levels of calcium and phosphate in the saliva of children with black dental stain were significantly higher compared to the levels found in the saliva of children without black dental stain.
