An In Vitro Scanning Electron Microscope Study of the Effects of External Tooth Whitening on Enamel Surfaces.

Objectives: The aim is to discuss, through an in vitro study, the effects of external tooth whitening on enamel surfaces using three methods.
Methods: It is an in vitro study conducted on a sample of 16 teeth divided into 4 groups. Each group was treated according to a technique.
Group 1: is a control group, having received no treatment.
Group 2: was treated according to the immediate technique with 40% hydrogen peroxide.
Group 3: was treated with 32% hydrogen peroxide in combination in combination with light.
Group 4: was treated with 16% carbamide peroxide.
The teeth were then preserved in physiological saline and observed with SEM.
Results: Typical pores and micro cracks alterations were observed for the concentrations of 40% and 32% hydrogen peroxide and they were more pronounced at 16% carbamide peroxide. These alterations were alleviated through the application of remineralizing products and immersion in saliva.
Conclusions: Although the whitening products can microscopically alter the enamel, this damage is minimal and quickly restored thanks to the buffering and remineralizing capacity of saliva.
