BACKGROUND: Volatile @entity599 compounds (VSCs) produced inside the mouth are a well-known cause of @entity7868 . Recent studies have suggested that VSCs modify the pathology of @entity2521 by encouraging the migration of bacterial toxins associated with increased permeability of @entity2522 , and enhancing the production of matrix metalloproteinases in gingival connective tissue. Nonetheless, the effects on the enamel of direct exposure to @entity1697 remain unclear. In the present study, we observed the effects of VSCs in the form of @entity3957 ( @entity3958 ) on enamel surfaces and determined their effects on restorations. MATERIALS AND METHODS: Extracted @entity1 tooth and @entity291 tooth samples were divided into the @entity3958 experimental side and the control side. We observed the effects of @entity3958 on enamel surfaces using electron microscopy and conducted a shear test. RESULTS: We found that exposure to @entity3958 obscured the enamel surface's crystal structure. The surface also exhibited coarseness and reticular changes. Shear testing did not reveal any differences in bond strength. CONCLUSIONS: Our findings suggested that @entity3958 occurring inside the mouth causes changes to the crystal structure of the enamel surface that can lead to tooth wear, but that it does not diminish the effects of dental bonding in adhesive restorations.
