When must a practicing dentist query the KASPER system?

Querying the KASPER (Kentucky All Schedule Prescription Electronic Reporting) system is a critical responsibility for dentists in Kentucky when it comes to prescribing controlled substances. The correct course of action is to query the KASPER system before prescribing any scheduled II or III controlled substance.

This requirement is designed to help prevent prescription drug abuse and ensure that practitioners are aware of a patient's prescription history, allowing them to make informed decisions about their treatment. By checking the KASPER system, dentists can identify if a patient has received similar medications from other providers, which is vital for safeguarding patient health and adhering to ethical practices.

The other choices do not align with the legal obligations regarding prescription practices. Querying the KASPER system is not a requirement simply for performing dental procedures, nor is it contingent upon a patient’s request. Additionally, it is unrelated to the process of renewing a dentist's license, which involves different regulatory compliance unrelated to prescription practices.
