[Motives for placement and replacement of dental restoration]

Aiming to evaluate placement and replacement of dental restorations, a questionnaire has been elaborated and distributed in Clinics of the Operative Dentistry Department, Bauru Dental Scholl--USP, for the students to point out some information about the operatory procedures performed. The analysis of the results made possible the observation that of the 241 restorations achieved, 45.64% were made due to primary caries and 54.36% were replacement of deficient restorations. The reasons for replacement as well as the possible factors responsible for failure of tooth-colored and amalgam restorations are analyzed and discussed.
