Insights into the clinical effectiveness of whitening products. Part 2 Dentist-supervised-at-home LED gel bleaching product

Abstract

This section of the report is about the success of a dentist-supervised-at home LED gel tooth whitener, giving the results of a clinical study. The product (LED light gel with 44% carbamide peroxide) was applied by the dentist on teeth 11 and 21 in the chair for 10 minutes. The process was repeated three times, followed by an athome treatment period (30 minutes/day) of 14 days with 35% carbamide peroxide. The treatment was as outlined by the manufacturers. The L* value improved (more white) after the in-chair treatment with the LED system but showed no further significant increase after the 14 day at-home treatment. However, the b* value improved (less yellow), after both the LED treatment and 14 day athome treatment. The a* value did not improve significantly throughout the treatments. The LED system provides inchair tooth whitening after a 14 day treatment although not as effectively as does Opalescence.
