Abstract
Objective: The aim of the study was to investigate color change, color stability and post bleaching hypersensitivity after performing 3 bleaching protocols, (LASER-activated, light-activated and chemically-activated) at different time intervals.
Methods: Patients were randomly assigned into three treatment groups (n=13). Group A received laser bleaching (J.W. Power Bleaching NEXT, 35 % hydrogen peroxide), group B received light-activated bleaching (Philips ZOOM, 25% hydrogen peroxide), and group C received chemical activated bleaching Dash Philips, 30% hydrogen peroxide). Each group received the treatment according to the manufacturer’s recommendations, followed by the desensitizing agent of each kit. Outcome assessment was performed for teeth shade and post bleaching hypersensitivity preoperatively, immediate, three months, and six months post-operatively using a spectrophotometer (Vita Easyshade, Vivadent, Germany).
Results: The study showed that there was no significant difference in color change between the three tested groups. LASER-activated bleaching protocol showed no significant difference in median ∆E throughout the study. Light activated bleaching showed decrease in median ∆E three to six months while in chemical-activated bleaching from zero to three months. Post-bleaching hypersensitivity, results showed no significant difference between the three tested groups.
Conclusion: All three bleaching methods can be used upon individual’s preference. LASER-activated bleaching group showed superior color stability over time. It can be satisfactory for patients seeking good results with reduced chair time.
