An in vitro investigation of the penetrating efficacy of BIS-GMA resin pit and fissure coatings
KR Powell
and
GG Craig
The frequency of complete penetration of two commercial BIS-GMA resin pit and fissure coating materials into wide and constricted fissures was assessed from photomicrographs. It was found that 334 of the 390 wide fissures examined were completely filled by the coating materials. However, in contrast, only 28 of the 650 constricted fissures examined were completely filled by these resins.
