What does direct dentin stimulation involve?

1. Injecting anesthesia into the pulp

2. Scratching the exposed dentin to check for pain

3. Applying heat to the tooth surface

4. Using chemicals for cleaning

The correct answer is: Scratching the exposed dentin to check for pain

Direct dentin stimulation involves scratching the exposed dentin to observe if there is a response in terms of pain or discomfort. This method is crucial because it helps assess the vitality of the pulp tissue beneath the dentin and the health of the tooth's structure. When dentin is scratched, it can cause fluid movement within the microscopic tubules in the dentin, potentially leading to stimulation of nerve endings. This response can indicate whether the tooth is still vital or if there may be underlying issues such as pulpitis. By distinguishing pain from healthy tissue versus compromised tissue, practitioners can make informed decisions on necessary interventions or treatments.
