GINGIVAL RESPONSE TO A NEW MULTIPURPOSE DENTAL ADHESIVE - A HISTOLOGIC-STUDY IN DOGS

The biocompatibility of cementing materials is a prerequisite for any dental procedure. In this study, the tolerance of gingival tissue to a n advanced fourth-generation dental adhesive (High-Q-Bond) was tested in dogs. The results from High-Q-Bond adhesive were compared with thos e obtained from Superbond C&B adhesive. Buccal class V subgingival cav ities were restored with either High-Q-Bond or Superbond C&B adhesive. Untreated teeth served as normal intact controls. The teeth with the attached buccal gingivae were extracted and processed for histologic e xamination. The histologic observations showed an inflammatory respons e in the gingiva of the Superbond C&B adhesive-treated teeth, whereas the High-Q-Bond fillings exhibited no noticeable adverse effect on the gingival tissue.
