Tooth bleaching (combined in-office and home bleaching) vs No bleaching (untreated control)

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Patients with post-orthodontic white spot lesions and permanent dentition

In the single RCT, all bleached patients were satisfied with the aesthetic outcome, though the trial was at high risk of bias (ungraded).

Metal-free FDPs (zirconia ceramic) vs Metal-ceramic FDPs

Patient satisfaction (measured by patient satisfaction or aesthetic scales) · Adults (18 years or older) needing a three-unit fixed dental prosthesis (FDP)

It is very uncertain whether metal-free FDPs (zirconia ceramic) changes aesthetic evaluation (patient aesthetic satisfaction changes) compared with metal-ceramic FDPs (very low certainty).
