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 an advanced fourth-generation dental adhesive (High-Q-Bond) was tested in dogs. The results from High-Q-Bond adhesive were compared with those obtained from Superbond C&B adhesive. Buccal class V subgingival cavities 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 examination. The histologic observations showed an inflammatory response 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.
