The effectiveness of an indicator gel in the detection of exposed dentine

Objectives: To investigate the effectiveness of an indicator gel in revealing exposed dentine. Methods: Teeth prepared into dentine and then stained with the indicator gel were sectioned for histological examination. Results: The indicator gel was found to stain dentine and thin layers of enamel. Conclusion: The gel is suggested to be an effective indicator as an aid to acid etching and in the preparation of teeth for resin-bonded restorations.
