This investigation evaluates the influence of several process variables upon the number of attendances required to complete orthodontic treatment provided by the hospital service of England and Wales. The hospital records and study casts of 1630 patients were collected from 17 District General Hospital Departments. The study casts were analysed with the Peer Assessment Rating. The following information was collected from the hospital records; the patients' sex, the number of attendances required to complete treatment, the type of treatment provided and the operator. The data were analysed with multiple regression techniques. It appeared that the number of attendances was influenced by the pretreatment malocclusion severity, the type of treatment, the experience of the operator and the department from which the treatment was delivered.
