DENTAL BLEACHING IN SMOKERS
Abstract:
Tooth whitening is an increasingly common treatment in dental offices, being a minimally
invasive solution for patients who want changes in tooth colour, compared to other techniques such as
prosthetics. The study aims at the durability over time of the results obtained after in-office teeth
whitening treatment in a single session, with Opalescence Boost 40% (hydrogen peroxide). Patients
were divided into equal groups of smokers and non-smokers, they were performed professional
hygiene and then the first colour determination was performed. The teeth whitening session followed
and the colour was determined immediately after in both groups and then six months after the
whitening treatment. Opalescence Boost 40% proved its effectiveness in a single session (2
applications of 15 minutes), the dental sensitivity after treatment being low, due to the fluoride present
in this substance. The immediate result of teeth whitening treatment is not affected if the patient
smokes, but the durability, colour retention are superior in non-smokers. In some cases the colour
changes ranged from one colour range to another (from A2 to B1).
