Dental attendance after treatment under dental general analgesia (DGA): a data-based follow-up study.

Patients who need DGA are evidently risk patients considering dental attendance. Nearly half of the patients in this study had non-attended or cancelled appointments. DGA patients' need of treatment after DGA is extensive, even comparable to the amount of procedures generally performed under DGA. The quality or amount of preventive procedures do not appear to be at the required level to reduce the number of non-attended appointments.
