Bacteria‐tight sealing of exposed dog pulps

Summary 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.
