Preoperative Anxiety and Its Influence on Patient and Surgeon Satisfaction in Patients Receiving Dental Implant Surgeries Performed Under Intravenous Conscious Sedation

Purpose: The aims of this study were to evaluate the relationship of age, sex, and type and duration of the surgery with preoperative anxiety in patients undergoing dental implant surgeries under intravenous conscious sedation, and to assess preoperative anxiety association with the postoperative satisfaction of both the patient and surgeon. Materials and Methods: This prospective study included 180 patients receiving dental implant surgeries under intravenous conscious sedation by means of midazolam, fentanyl, and propofol. Preoperative anxiety (Corah Dental Anxiety Scale), number of implants, duration of surgery, surgeon satisfaction (evaluated as three categories: patient too awake and nervous, adequate sedation, or patient too asleep), and patient satisfaction (classified as five levels: agreeable, neither agreeable nor disagreeable, slightly uncomfortable, unpleasant, traumatic) were recorded. Results: All 180 patients completed the study, and 72.2% of them experienced moderate or high levels of anxiety. The mean Corah scale score was 9.2 ± 3.5. Anxiety was significantly higher among men but showed no relation to age. A significant relationship was found between patient anxiety and the number of implants: those patients who received eight or more implants, with a duration of surgery longer than 60 minutes, had lower anxiety. Surgeon satisfaction was adequate in 90% of the cases. Patients evaluated the procedure as agreeable in 34.4% of cases, neither agreeable nor disagreeable in 26.7%, slightly uncomfortable in 29.4%, unpleasant in 7.8%, and traumatic in 1.7%. High anxiety levels were related with poor patient satisfaction but not with surgeon satisfaction. Conclusion: Preoperative anxiety was moderate or high in two-thirds of patients undergoing dental implant surgeries, having a negative influence on patient satisfaction, but not affecting surgeon satisfaction. Additionally, the intravenous conscious sedation technique was considered a satisfactory technique by the surgeon to control anxiety.
