Work study on endodontic treatments by means of practice administration.

Work analysis by means of dental practice administration is necessary for every clinical dentist. Generally speaking, endodontics sometimes may ignore the study of the operator's difficulties and/or the patient's time burden. Two dentists had treated 72 teeth on 49 patients with single visits in endodontics in one month. Vital and infected canal treatment needed almost the same working time in our clinical system. Difficult cases and work factors affect working time longer and make the standard deviation larger. Difficulties had caused incisor work to consume more time than premolar treatments. In the case of molars, clinical experience helped treatment on maxilla to be quicker than on mandible. Knack factors were to be revealed in this qualitative study.
