Different applicabilities of the etch-bleach-seal technique for treating opacities on permanent incisor damage by molar incisor hypomineralisation in three young patients.

Enamel opacity on anterior teeth can be prejudicial for the aesthetic appearance of affected patients. Patients with molar incisor hypomineralisation, for example, present opacities that can range from discrete white mottling to extensive yellow-brown discolourations. They can request a treatment to improve their aesthetic conditions. Many techniques have been considered to manage this condition. Wright developed a technique called etch-bleach-seal, which showed promising results for the management of anterior enamel opacities. The aims of this report are to present this technique and to analyse its benefits and inconveniences.
