Determinants of receiving intravenous sedation in a sample of dentally-fearful patients in the USA.

Dental fear may be the most common reason for referral for intravenous sedation. Intravenous sedation offers many patients an opportunity to obtain needed dental care. However, intravenous sedation also has costs and may not help patients overcome their fear. Given a sample of 518 dentally-fearful patients in the USA presenting for dental care, this study examined the variables which predicted receiving intravenous sedation or not. About one-fifth of the patients received intravenous sedation, while the others received only cognitive behavioural therapy. Having more carious teeth, higher dental fear, more negative beliefs about dentists, lifetime diagnoses of panic disorder and/or generalized anxiety disorder, fewer existing coping skills, and a lower desire to cope with the dental situation were each predictive of having intravenous sedation. When the variables were considered simultaneously, only lower desire to cope contributed uniquely to the prediction. In a setting where psychological treatment for dental fear is available, patients' desire to cope with their fear was the most important factor in determining whether they received intravenous sedation or not.
