Effect of using low-viscosity resinous infiltrant (Icon®) to prevent carious lesions around orthodontic brackets: a randomized clinical study

For the group treated with the Icon ® resinous infiltrant, the ICDAS index values remained stable, T0 (application of the resinous infiltrant) (M = 0.062; SD = 0.162), T1 (six months after application) (M = 0.062; SD = 0.162) and T2 (one year after application) (M = 0.073; SD = 0.164) and showed no statistical differences (p = 0.500). For the control group (fluoride-free placebo agent) there were significant variations over time (p <0.001), with average increases at all times evaluated (p <0.001).
