Effect of Low-intensity Laser and Photodynamic Therapy on Infected Dentin of Permanent Teeth With MIH

For the aPDT the PapacarieMblue (Fórmula e Ação) was used. It was left for 5 minutes in the cavity. The carious tissue was removed and the application of the PapacarieMblue was repeated. The tissue was then irradiated in a single spot with a red laser, of wavelength of 660 nm, for 300 s, with the energy of 500mJ. These parameters were also applied in the vestibular root of the teeth, to try and prevent sensitivity.

Removal of infected dentin with a curette only, followed by cavity cleaning and restoration with glass ionomer cement.
