1450 ppm fluoride toothpaste brushing x Resin sealing (FluroShield, Dentsply, Brazil).
ProcedureAfter randomization of the children, the selected molars were allocated through a randomized sequence list in 2 groups: A. Brushing with 1450 ppm fluoride toothpaste, donated by the researcher; B. Resin Sealing (FluroShield, Dentsply, Brazil).
The teeth included in the second group (group B) underwent a second randomization: B1. With absolute isolation; B2. With relative isolation. For the group with absolute isolation, topical anesthesia and local papillary infiltration were performed for subsequent staple placement. Relative isolation was performed with cotton rollers and moisture control suction. The sealant selected was the opaque fluroshield to facilitate visualization upon visual examination during reevaluations and was applied following the manufacturer's standards. The teeth were clinically and radiographically followed at 6 and 12 months and two sessions of motivation reinforcement were performed through video and brush change at 3 and 9 months.
