title: Bacteria-tight sealing of exposed dog pulps.
abstract: Penetration of bacteria past filling materials can interfere with the vitality of exposed pulps. In the present study, seventy-three dog's teeth were filled--after exposure--with Cavit -W and then sealed either with a chemically or a UV polymerizing bonding. After 14 days a failure rate of 28% was demonstrated using the chemically polymerizing Concise and of 4.5% using the UV polymerizing Uvio -Bond. After 42 days the latter bonding revealed a success rate of 100%. To achieve a bacteria-tight seal of deep cavities for middle long term animal experimentation, Uvio -Bond can be used--after etching--to cover the filling material and the surrounding enamel.
