Objective:
To assess referrals to sedation, examining dental anxiety and background of patients, and compare these characteristics to those referred to a restorative dentistry clinic.
Design:
Descriptive, cross sectional survey.
Subjects And Methods:
Subjects were 100 consecutive new patients in sedation and special care and 50 new patients in restorative dentistry at Guy's and St Thomas NHS Foundation Trust. A questionnaire included demographics, self-reported oral health and dental attendance, and dental fear. Information from the patients records was taken: ASA classification, previous sedation or general anaesthesia, alcohol and tobacco use, and medications.
Results:
The best predictors of referral were dental anxiety level and an irregular attendance. The most important fears were seeing, hearing and feeling the vibrations of the dental drill, and the perception of an accelerated heart rate. Other factors such as general, mental and dental health and alcohol use were related to referral but less important.
Conclusions:
Referral is consistent with the goal of the sedation clinic to see anxious patients. Referring general practitioners are able to identify these patients.

Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...
