ABSTRACT OF THE DISCLOSURE A peroxide-catalyzed composition useful for the sealing of pits and fissures in teeth to prevent decay therein comprises from about 40 to about 60 parts by weight of a mixture of BIS-GMA and from 0 to about 3 parts by weight BADM for every 9 parts BIS-GMA, from about 60 to about 40 parts by weight of TEGDM, and amounts of peroxide catalyst and N,N-bis- (2-hydroxyethyl)-3,4-dimethylaniline as accelerator for the catalyst such that the set time of the composition is from about 40 to about 90 seconds, all of the catalyst and the accelerator is dissolved in the composition. This composition has a contact angle with respect to dry etched tooth surface tooth of less than 10° and a Brookfield viscosity of up to about 1200 centipoises.
