Disclosing solution is the material that can help us to see dental plaque. Chemical disclosing solution, which now exists, has several disadvantages so we need to develo p natural disclosing solution. One of the ingredients in natural disclosing solution that has been studied for its effect is betacyanin, which is contained in super-red dragon fruit (Hylocereus costaricensis). This study aim to observe the coloring effect of super-red dragon fruit juice . Th e experimental was conducted by measuring plaque index of 20 people, who were not to clean their teeth for 24 hours (two periods), and were eat en the same foods in each period. Examination of plaque index at the end of the first period use d chemical disclosing solution contains of erythrosine (FDC Red #3) and the second period use d super-red dragon fruit juice . The data s were analyzed by P aired T-test. The results of the plaque index score at the first (2.47815 ± 0.811497 ) , the second (2.7731 ± 1.0512 ) and did not find a significant difference (p > 0.05).
