Prevalence of Patients Receiving Dental Treatments Under Sedation: A Retrospective Study

Background: The objective of the study was to assess the prevalence of patients under sedation for dental treatments and to compare patients under either deep sedation with ketamine (DSK) or general anesthesia (GA). Methods: This retrospective study included 28 patients among 11581 clinical files over the last 5 years. All patients received dental treatment either under DSK (n=6) or GA (n=22). Demographic and clinical data were recorded. Results were reported as mean ? standard deviation and frequencies, the fisher exact test was used for comparison with significant p value less than0.05. Results: The prevalence of patients under sedation was 0.024%. The mean age was 20.4 ? 16.1 with male predominance (60.7%).Most of patients were referred by other departments (64.3%) and nearly 80% of them had a systematic condition. Of these, 60.7% suffered from a mental disorder. In fact, in these patients (n=18) GA was most commonly performed (pless than0.02). Indeed, there was a significant difference regarding the mean age between patients under DSK vs those under GA, 8.16 years ? 3.25 vs 22.31 years ? 16.81 respectively. (81.8% vs 16.7%, p less than0.02).Finally, tooth extraction was the most common treatment (67.8%). Conclusion: Within the limits of the present study, the prevalence of patients receiving dental treatment under sedation is low. Most patients with a mental disorder were treated under GA.
