The subjects in this study were active students in the Social and Political Sciences Faculty 2017 using a fixed orthodontic appliance for 1 to 2 years. Then the sample selection using non probability sampling technique that was with total sampling technique. Result: The highest plaque index score is 2 owned by female respondents and the lowest plaque index score is 0.6 also owned by female respondents.
