Study notes
A 25-year-old patient comes in with a cavity on tooth #36. Diagnosis: Class I caries. Treatment: 1. Isolate the tooth using a rubber dam to keep saliva out. 2. Remove decay with a #330 carbide bur. 3. Clean the cavity with 2% chlorhexidine. 4. Apply a biocompatible glass ionomer cement (GIC) base. 5. Place the composite resin. Outcome: The patient feels no sensitivity because the GIC acts as a buffer between the chemical resin and the tooth nerve. Follow-up: 6 months later, the gum is healthy and pink, showing good biocompatibility.
