CONTEXT One of the goals of endodontic therapy is the shaping and cleaning of the root canal system. In recent years, there has been multiple systems instrumentation, and changes in their dynamics are central to maintain the original shape of the canal after preparation. AIMS The aim of this study was to evaluate centering and transportation in curved root canals after using ProTaper(®) and M...
We describe an approach to study the long-term use of GUI applications that supplements a log of low-level events with additional data gathered at the applications’ architectural boundaries. We implement a preliminary system based on this approach and apply it to two applications. For the second application, we compare the data collected with our technique to data collected with manual instrume...
Background and purpose: The purpose of mechanical cleaning of the root canal is to clean the canal walls, create a conical shape to facilitate access, effective washing, and filling all areas of the root canal. Errors such as root canal transportation are cuased by excessive dentin removal from the canal. The objective of this study was to investigate root canal transportation by a BT Race rota...
Aim: To evaluate the foraminal transportation during foraminal enlargement after manual instrumentation with stainless steel files, preparation with the Mtwo system and Reciproc R25 file. Methods: Thirty roots were selected, divided in three groups and prepared in accordance with the different instrumentation systems: Hand Files (HF); Mtwo system (MS); and Reciproc system (RS). All groups were ...
OBJECTIVES The debridement of diseased root surface is usually performed by mechanical scaling and root planing using manual and power driven instruments. Many new designs in ultrasonic powered scaling tips have been developed. However, their effectiveness as compared to manual curettes has always been debatable. Thus, the objective of this in vitro study was to comparatively evaluate the effic...
