THE EFFECTS OF SURGICAL EXPOSURES OF DENTAL PULPS IN GERM-FREE AND CONVENTIONAL LABORATORY RATS
Evidence-based Endodontics Literature Database. Title: The effects of surgical exposures of dental pulps in germ-free and conventional laboratory rats. No attempt was made to restore or seal the exposure which allowed food, debris and microorganisms in the conventional rats to become impacted into the pulpal tissues. The animals were then sacrificed at intervals from 1 to 42 days post-op. The tissues were serially cut in a mesiodistal plane, stained and studied microscopically.
