Local anesthesia (LA) forms the backbone of pain control techniques in dentistry. The receipt of a LA injection is, unfortunately, the most traumatic part of the dental procedure for most patients. Trypanophobia (fear of needles) is estimated to be present in ~10% of the world’s population. Fainting during LA injection is, far and away, the most common medical emergency encountered in dentistry. The ability to obtain profound pulpal anesthesia for restorative dental procedures without injection will enable a dentist to provide comfortable, safe and effective treatment to many needle-phobic persons who previously avoided seeking dental care.

An intranasal local anesthetic mist – a combination of tetracaine HCl and oxymetazoline – has been developed that provides pulpal anesthesia to the maxillary non-molar teeth. In this program Dr. Malamed will discuss the problem of needle-phobia as well as the development and efficacy of this new intranasal local anesthetic mist.

Learning Objectives:

  1. Name the five currently available dental local anesthetics and their expected durations of action
  2. Describe the incidence of syncope as a medical emergency in dentistry as it related to the problem of needle-phobia (trypanophobia)
  3. List the advantages of tetracaine HCL for use as an intranasal local anesthetic mist and explain the rational for the inclusion of oxymetazoline.
  4. Discuss the results of the FDA Phase 2 and 3 adult clinical trials comparing K305 to tetracaine and to placebo
  5. Discuss the results of the FDA 3 pediatric clinical trial comparing K305 to placebo
