Abstract: English summary Adhesion to eroded tooth substance. A case report Nor Tannlegeforen Tid. 2024; 134: 684-7. Background: Dental erosion is a common form of tooth wear and is a clinical consequence of exposure to non-bacterial acids. Restorative treatment may often be necessary in these patients, and a minimally invasive approach with adhesives and directly applied composite is becoming more common. Case study: A 40-year-old healthy man presented with concerns about both aesthetics and symptoms from his teeth. Clinical examination revealed occlusal/incisal erosion defects on all teeth in the upper and lower jaw. The defects clearly extended into dentin. A restorative treatment with composite was planned without changing the occlusal-vertical dimension. The affected dentin surfaces were roughened with a coarse diamond bur, without further cavity preparation. Rubber dam was used, the adhesive applied with an etch-and-rinse strategy, and the defects restored with composite. Conclusion: The bond strength to an eroded enamel surface is not different from an intact enamel surface, regardless of adhesion strategy. However, the bond strength to eroded dentin is poorer than that to healthy dentin. Hence, it is recommended to roughen up the dentin surface with a coarse diamond before adhesive treatment.
