Photobiomodulation and Glass Ionomer Sealant as Complementary Treatment for Hypersensitivity in Molars With MIH

The participants received oral hygiene instructions - routine brushing twice per day with toothpaste containing 1000 ppm of fluoride. All participants received a toothbrush and toothpaste to ensure standardization. The aim of this intervention was to assess whether the participants' brushing technique would improve with desensitization.

"For laser application, the following dosimetric parameters will be used:~Low level laser diode (infra red) wavelength 808nm with a power of 100mW. Three sessions: initial session, after 48 hours and after one month. LLL was applied to three perpendicular points in contact with the surface on the mesial vestibular and distal cervical faces and in the center of the occlusal face. An energy of 1 J was applied for 10 seconds at each point."

The same application described in the laser therapy group will be simulated, with the device turned off.

A glass ionomer sealant will be applied to the occlusal surface of the first permanent molar.
