OBJECTIVE: To investigate salivary cortisol levels in patients undergoing third molar removal under local and general anaesthesia. DESIGN: Random sampling of two independent groups. METHODS: Samples of saliva were collected from patients prior to and after surgery for the removal of impacted wisdom teeth. The samples were analysed to assess cortisol levels. Patients were also asked to complete a Hospital Anxiety and Depression questionnaire on the day of surgery. RESULTS: Patients receiving treatment under local anaesthesia showed lower levels of stress response than those having treatment under general anaesthesia on the actual day of surgery did (Fig. 1). No other significant differences were noted. CONCLUSION: Local anaesthesia is the preferred mode of pain control for patients who express no strong preference for type of anaesthetic.

PURPOSE: The purpose of this study was to evaluate the effect of oral premedication with midazolam on recovery times of children undergoing dental restorations under general anesthesia. METHODS: The records of 106 children (1.2-11.3 years, ASA I or II) undergoing ambulatory dental restorations were randomly selected and retrospectively reviewed: 50 subjects received midazolam (M) 0.5 mg/kg orally approximately 30 minutes prior to their procedure and 56 control subjects received no premedication (C). General anesthesia consisted primarily of inhalational anesthesia. Time in the operating room (OR), post-anesthesia care unit (PACU) and same day surgery (SDS) were determined and compared between groups. RESULTS: Both groups were similar with respect to age and weight. There were no significant differences between groups in time spent in the OR, PACU or SDS (p>0.05). In a subset of children having shorter dental procedures (OR time < or =75 minutes, n=29), there remained no significant difference in discharge times between groups. CONCLUSIONS: Preoperative administration of oral midazolam does not delay discharge of children undergoing general anesthesia for dental rehabilitation.
