    Abstract

    Appropriate stress management of patients is essential for smooth running of invasive or surgical dental procedures conducted under local anaesthesia. Objective: The current study analysed the effectiveness of pre-operative information provision for anxiety reduction during dentoalveolar surgery in patients with high- or low-trait anxiety. Methods: Patients scheduled for oral surgical procedures performed by six private dental practitioners were invited to participate in the study. They were randomly assigned to four groups and received the following pre-operative information: (i) basic information only, (ii) basic information with details of the operative procedures, (iii) basic information with details of the expected recovery, and (iv) basic information with details of both the operative procedures and recovery. The participants' trait anxiety level was measured with the Depression Anxiety Stress Scales (DASS), then they were divided into high- or low-trait anxiety groups with the method of median-split on the basis of the DASS score. Self-rated anxiety was recorded immediately before, during and 10 min after the surgical procedures. Results: High-trait anxiety subjects gave higher self-reported anxiety levels (repeated-measures ANOVA, P < 0.05). Pre-operative provision of details about the expected recovery only or details concerning both the operative procedures and recovery led to significant reduction in self-reported anxiety among the participants throughout the procedure (P < 0.01). However, information on operative procedures led to anxiety reduction in low (P < 0.05) but not high-trait anxiety participants. Conclusion: Provision of pre-operative information of the recovery process leads to significant anxiety reduction in all patients who undergo surgical/invasive procedures with local anaesthesia.
