Effects of subgingival restorations in beagle dogs. Part II: Gingivitis

For the materials and time period used in this study it was found that: 1. At the end of the study there were no significant differences recorded between the restored teeth with either the gingival index or the histologic inflammation index. 2. The gingival index showed that during the study the overall gingival health of the control teeth had improved significantly, while the overall gingival health of the restored teeth had improved only slightly. 3. At the end of the study the histologic inflammation index, but not the gingival index, showed significantly more gingivitis overall for the restored teeth than for the control teeth. 4. A comparison of the gingival, histologic inflammation, and microorganism (from Part I) indices, used to assess either the gingival condition or the amount of subgingival plaque on the restored teeth, showed no association between any of them. 5. In general, the degree of clinical and histologic gingivitis associated with the restored teeth was slight.
