Patient Satisfaction With At-home Dental Bleaching Using Orthodontic Retainers With Different Margin Designs

Patient satisfaction was assessed during 2 weeks of whitening with a scalloped orthodontic retainer. Colour change, TS and IG were also measured. No studies have evaluated the effect of different margin designs in orthodontic retainers used in for tooth bleaching. Therefore, the present study aimed to clinically assess the impact of scalloped and straight margin design in orthodontic retainers employed for at-home bleaching, considering patient satisfaction, bleaching efficacy, tooth sensitivity (TS), and gingival irritation (GI).

Patient satisfaction was assessed during two weeks of whitening with a straight orthodontic retainer. Colour change, TS and IG were also measured. No studies have evaluated the effect of different margin designs in orthodontic retainers used in for tooth bleaching. Therefore, the present study aimed to clinically assess the impact of scalloped and straight margin design in orthodontic retainers employed for at-home bleaching, considering patient satisfaction, bleaching efficacy, tooth sensitivity (TS), and gingival irritation (GI). The null hypotheses were that no significant differences would be observed in: (1) patient satisfaction, (2) bleaching efficacy, (3) tooth sensitivity, and (4) gingival irritation, when different margin designs are used in orthodontic retainers for at-home tooth bleaching.
