Introduction: Cleanup, the tooth-coloured adhesive used in orthodontics is time-consuming which may cause the iatrogenic enamel damage. Various techniques have been proposed to reduce the operator-sensitivity of the composite detection procedure. Applications of ink dye and 0.2 brilliant green solutions and articulating paper are some examples. Aim: To compare the staining effects of Turmeric-Persica solution and Turmeric-GC-MI Plus paste on remnant adhesive on teeth after bracket debonding. Materials and Methods: Forty metal brackets were bonded to 40 caries-free extracted premolars. After debonding, teeth were randomly divided into two groups of 20 each. Teeth in Group 1 (G1) were immersed in Turmeric-Persica solution while in Group 2 (G2) Turmeric-GC-MI Plus paste was applied to the buccal surface of the teeth. After rinsing and drying, all the specimens were photographed under standard situations and analysed by MATLAB software to evaluate the colour differences between enamel and adhesive. Collected data were statistically analysed by SPSS version 16.0 and compared by Mann-Whitney U test. The significance level was considered to be 0.05. Results: The mean cross-border yellowness was significantly higher in G2, turmeric-GC-MI Plus paste, than G1, turmeric-persica solution. (with a p-value: 0.005). Conclusion: Turmeric powder mixed in GC-MI Plus paste could be used as a disclosing material for adhesive resin applied to tooth surface.
