Implication

Randomized clinical trial compares internal bleaching outcomes in maxillary anteriors, suggesting Opalescence Endo is more effective.

Key Points

The aim is to compare the effectiveness and patient satisfaction of Opalescence Endo and 30% hydrogen peroxide with sodium perborate in internal bleaching.
122 discolored root canal-treated teeth randomly divided into two groups: Opalescence Endo and 30% hydrogen peroxide with sodium perborate.
Bleaching sessions conducted at 7-day intervals, with a maximum of three sessions.
Efficacy assessed using a 5-point Visual Analog Scale and CIELAB metrics including L* values.
Opalescence Endo showed significantly better L* values (81.66) compared to 30% hydrogen peroxide (83.52).
The average days for bleaching was shorter for Opalescence Endo (16.76 days) compared to hydrogen peroxide (21.80 days).
Patients noted a faster color change with Opalescence Endo (1.95 days) than with sodium perborate (3 days).
For severely discolored teeth, Lightness Recovery Percentage was better for Opalescence Endo (72.97%) than for 30% hydrogen peroxide (53.17%).
Both methods provided high patient satisfaction over a 12-month period.
