Abstract
A composition and method adapted for discernibly filling and sealing pits and fissures in tooth surfaces is described. The novel compositions contain finely divided hydrophobic opaquing filler and hydrophobic suspending agent, in defined amounts, in a polymerizable resin system. Placement of the composition on dental surfaces is simplified and retention is easily verified.
