A new method is developed for predicting shade improvement after teeth bleaching

This means that, so far, dentists have been unable to predict the results for patients' teeth. This means that dental physicians could not inform their patients on the shade improvement that the treatment would bring about, which was a limitation to the therapy.

The study was conducted by Janiley Santana Daz, at the Department of Stomatology of the University of Granada and was coordinated by professors Rosa M Pulgar Encinas, M Del Mar Prez Gmez and Luis Javier Herrera Maldonado. Using a fuzzy rule system, scientists had a first approach to the shade improvement that teeth can get after undergoing a 20% carbamide peroxide treatment (Opalescence PF 20%, Ultradent) two hours a day for two weeks.

Participants

For the purpose of this study, authors took a sample of 53 subjects that subsequently underwent a teeth bleaching treatment. Before the bleaching treatment, participants answered a questionnaire on their eating habits so that sc
