An increasing number of German dentists are expanding their practice to include conscious sedation in their offices. N2O sedation has an unparalleled track record for safety, efficacy and convenience4. Studies have shown that dentists can learn the essentials of safe N2O sedation and perform well under rigorous testing following a 16-hour N2O postgraduate course employing the modified educational standards of the EAPD and the AAPD5. In this study an overwhelming majority of patients followed their dentist’s recommendation for inhalational N2O sedation
and only 6% said that they would not ask for the same treatment again.

From the dentist’s point of view, 9 out of 10 patients did well with this technique and only one patient in the study had to abort the procedure and be re-scheduled for general anesthesia. N2O sedation is a growing field within dentistry and this study found two primary explanations for this growth: a high level of satisfaction among both dentists and patients and no adverse effects or complications.

Nitrous oxide is universally recognized as the safest and most effective technique for conscious sedation in dentistry, provided that the dental professionals are rigorously trained. Pediatric dentists have been leading the way in establishing high standards of care. Increasingly, general dentists have been entering training programs in order to offer sedation to their patients of all ages. Accessibility of dental nitrous oxide and educational opportunities to learn its proper use vary among the European countries. Germany does not have legally-binding national standards for dental nitrous oxide sedation. Providing high-quality post-graduate education to dentists with little or no undergraduate training in nitrous oxide use can contribute to an increase in the number of patients accepting professional dental care. This positive contribution to oral health can be effectively achieved with a two-day course led by professional anesthesia personnel and dental educators. Standardized testing serves as a method of quality assurance for both the course participants and the medical educators.
