The acceptability of the use of sedation in the management of dental anxiety in children: views of dental students

The aim of the present study was to determine the views of dental students concerning the acceptability of the use of sedation in the management of dentally anxious children. Dental students in Trinidad (n = 100) were asked to rate the acceptability of vignettes describing the management of a young teenager with dental anxiety. The vignettes varied systematically along two dimensions: nature of intervention for anxiety (sedation vs. the use of relaxation training and rewards) and outcome of the intervention (good vs. poor). Ratings of acceptability were made using a standardized questionnaire measure. The data were analysed using analysis of variance (ANOVA). There were significant main effects of nature of intervention (F = 5.54; P < 0.05) and outcome of intervention (F = 298.01; P < 0.001), though the students' year of study did not influence ratings. None of the interaction terms were significant. Sedation was viewed as a less acceptable intervention than relaxation and rewards. Interventions associated with good outcomes were seen as more acceptable than interventions associated with poor outcomes. It is concluded that dental students' perceptions of the acceptability of interventions for use with dentally anxious patients are related to the effectiveness of the intervention. Sedation, regardless of the outcome, is seen as less acceptable than the use of rewards and relaxation.
