Abstract
Objectives. This retrospective study aimed to evaluate teeth whitening effectiveness and sensitivity after procedure. Tasks: 1) to evaluate colour efficiency immediately after teeth whitening; 2) to validate colour stability after 12-15 months; 3) to evaluate teeth sensitivity. Materials and Methods. In total, 111 participants received in-office whitening of four 15- minute applications of 6% HP activated by Philips Zoom WhiteSpeed LED and take-home whitening kit containing individual trays and two syringes of 6% HP for 12 days. Colour changes were evaluated at baseline and immediately after the whitening session using the digital Easyshade V spectrophotometer (Vita, Zahnfabrik, Germany). Clinical colour stability was obtained by colour change in the spectrophotometer after 12 - 15 months. Teeth sensitivity was investigated instantly after the procedure. Results. 99,1% of participants teeth after whitening reached maximum values of B1 (80,2%) and A1 (18,9%). Only 0,9% of patients teeth reached A2 shade value. Shade value after 12-15 months reduces to close A1 and A2 values. There was a significant association between teeth whitening and colour stability (Fisher’s Exact p < 0.001). Only 1,8% of patients reported teeth sensitivity immediately after whitening. Conclusions. In-office whitening with low concentration of HP (6%) activated by Philips Zoom WhiteSpeed LED light combined with take-home whitening gel of 6% HP (DayWhite) used with individual trays for 12 days after the procedure were effective, permanent for up to 12-15 months post- whitening and nearly sensitivity-free.
