Fixed orthodontic treatment is a treatment in dentistry that aims to correct malocclusion. An important component of this treatment is orthodontic brackets and wires. When there is an interaction between the wire and the bracket, a resistance (friction) is formed. The formation of this resistance (friction) is caused by several factors, one of which is corrosion. The increased friction of the orthodontic bracket can cause various negative effects such as increased treatment time, toxic reactions, allergies, and even more costs for the treatment required. Several studies have proven that the content of orange peel is able to be an inhibitor of corrosion on wire and orthodontic brackets made of stainless steel, so that it can reduce or maintain bracket friction with use. Objective: to assess the ability of sweet orange peel extract (Citrus sinensis) in reducing friction on orthodontic wire and brackets. Research method: the research method used a quasi-experimental research object, namely 20 maxillary premolar brackets and 2 stainless steel orthodontic wires immersed in a solution of sweet orange peel extract (Citrus sinensis) with a concentration of 1000 ppm. Independent Sample t Test is used to compare the results between groups. Result : Extracts of sweet orange peel effect in maintaining bracket friction. This is evidenced by the average value of friction between the control group and the extract group which showed no significant difference between the control group (T0) and the extract-immersion group (T1). Conclusion : There is a difference in bracket friction value between the control group and the treated group. Thus, the sweet orange peel extract has an effect to maintain orthodontic bracket friction.
