Anethesia Efficacy on Teeth With MIH (Molar Incisor Hypomineralisation)

In experimental groups, before topical anesthesia, PBMT was applied by utilizing a diode laser (EpiX; Biolase technology, inc., USA) with a continuous wavelength of 940 nm on a 400-μm fiber with only biostimulation properties. In accordance with the recommendations of the device's manufacturer, it was applied using circular motions in a manner as slowly as possible (an average of 33-36 circular movements in 60 s)

In the control group (placebo), the laser probe was directed to the mucosa for (buccal and palatal area), but not activated, and the sound of the laser device previously recorded on the mobile telephone was played for the same time of experimental group in order to provide similar conditions
