Efficacy of Sealants in Cavitated Enamel Lesions on Occlusal Surfaces in Children

"Surfaces allocated to this group will be treated with resin-based sealant (FluroShield®, Dentsply, United States of America) according to the manufacturer's instructions.~Initially, local anesthesia and rubber dam adaptation will be performed. Then, 37% phosphoric acid will be applied on the surface for 30 seconds, followed by spray of water/air for at least 15 seconds. The sealant will be dispensed on the occlusal surface and light cured for 20 seconds (Optilight Max, Gnatus, Brazil)."

Surfaces allocated to this group will be treated with sterile water application, as a placebo, without anesthesia and rubber dam. The active treatment in this group will be only oral hygiene orientations.
