Highlights

The presence of dental caries is the main reason for the placement and replacement of restorations
The survival time of direct restorations has ranged from 03 to 08 years depending on the type of study and associated variables, such as the extent of the preparation and location of the restoration in the dental arch[3,11,12,13,14]
The dental service establishes a daily quantitative target of clinical procedures to be met by dentists during their working hours, on average 30 minutes per individual treated

Summary

Introduction

The presence of dental caries is the main reason for the placement and replacement of restorations. Maintaining restorations to a satisfactory clinical condition is a challenge, despite the evolution of materials and surgical operative techniques. Objective: To investigate the survival time and technical-operatory characteristics of dental restorations among adults in Teresina-PI. Technical and operatory variables had no influence on the survival time of restorations. Dental restorations have a low survival time and this fact might be associated with the decion-making process that is adopted by the professionals. Despite recent advances in the prevention of dental caries, the disease continues to be a global public health problem and is the main reason for the placement and replacement of dental restorations[1,2,3,4,5,6]. Diagnosing the reason for failures and the choice of treatment is a subjective process[1,2,3,4,5,6,7,8,9]
