Providing dental care to anxious and fearful patients continues to be a major challenge facing dentists. Despite advances in management techniques and treatment delivery, feelings of apprehension create psychological obstacles that prevent dental patients from seeking and receiving care.

Of the current techniques to facilitate coping or to minimize procedure apprehension, in-office enteral sedation or oral conscious sedation has garnered the most attention. Dental fear is a learned response as family, friends, and popular media can influence patients’ attitudes toward dentistry. Dentists have used numerous techniques to improve patient comfort during treatment, employing distraction techniques, calming dialogue, and positive reinforcement to manage anxious patients who otherwise would use the “white-knuckle” technique.

In recent years, the use of oral benzodiazepines such as triazolam and lorazepam (with or without nitrous oxide) for the diminution of perioperative anxiety and fear in dental patients has increased. State dental boards, in response, have changed or developed new regulations outlining the training and equipment needed for in-office anxiolysis and oral conscious sedation. Although state regulations for the provision of in-office anxiolysis and oral conscious sedation vary widely with respect to training and pharmacological strategies, consonance exists on the use of inherently safe drugs, the use of pulse oximetry, and the availability of emergency equipment including pharmacologic antagonists.

This dynamic lecture will cover both the science and art of oral conscious sedation in an interactive and engaging multimedia presentation.

Objectives to be covered:

• Discuss the principles of pharmacokinetics and pharmacodynamics.
• Understand the concept of bioavailability and half-life.
• Describe the continuum of consciousness.
• List the characteristics of the ideal sedative for in-office use.
• Discuss the advantages and disadvantages of oral conscious sedation versus other modalities.
• Describe the mechanism of action and pharmacological properties of the benzodiazepine family of medications.
• Match the right drug at the right dose to the right patient and the right procedure.
