Efficacy of sealants with surface pre-reacted glass (S-PRG) in retention, fissure penetration and occlusal caries Inhibition : Short title: efficacy of S-PRG sealants.

ABSTRACT:

Objectives

This in vitro study aimed to evaluate the effect of different application protocols of surface pre-reacted glass-ionomer (S-PRG) sealant on penetration ability, retention, and occlusal caries inhibition, in comparison with resin-based sealant (RBS) under simulated oral conditions.

Materials and methods

Eighty-four extracted human third molars were randomly assigned to five groups: S-PRG sealant applied per manufacturer's instructions (G1), S-PRG with 37% phosphoric acid etching pretreatment (G2), S-PRG with fluoride varnish pretreatment (G3), RBS (G4), and a no-sealant control (G5). Sealant retention was assessed through visual inspection following water storage at 37 °C and thermocycling, whereas penetration depth was evaluated using scanning electron microscopy
