Abstract
Objective Anxiety is an undesirable psychological phenomenon with multiple negative influences on patient compliance, treatment comfort, surgical conditions and postoperative outcome. In oral surgery patients are usually anxious, but the exact pattern is unknown. Therefore, the aim of this study was to assess the intensity and course of anxiety during oral surgery. Method & material In 48 patients (25±6 years old) a third molar was surgically removed under local anesthesia. During treatment, heart rate was continuously monitored as a measurement of anxiety. Preoperative anxiety was scored with a Dutch version of the Modified Dental Anxiety Score (MDAS). Patient’s anxiety level was analyzed by assessing the impact of individual events on heart rate. The events studied were the waiting room, sitting down in the dental chair, application of local anesthesia, application of surgical drapes, time-out procedure, incision, alveolotomy, removal of the third molar, suturing and the end of the procedure. The heart rate during these events were compared to determine if any changes in heart rate occurred during the whole treatment process. Results A significant increase in heart rate was observed when sitting down in the dental chair and when applicating the surgical drapes (p<0.005). A decrease in heart rate was measured after the onset of the administration of additional anesthesia (p<0.005). The lowest heart rate values were recorded in the waiting room (median 91.0 bpm), during application of anesthesia (88.5 bpm), during suturing (95.0 bpm) and at the end of the procedure (90.5 bpm). The highest values were obtained during the time-out procedure (104.5 bpm), incision (105.4 bpm) and the alveolotomy (102.0 bpm; p<0.005). Women revealed to have a higher mean heart rate than men (p<0.05). No correlation was found between preoperative heart rate values and preoperative MDAS score. Conclusion The intensity and course of anxiety has a specific pattern during oral surgery treatment, in which the most stressful period is experienced before the third molar actually is removed.
