Shaping of the Root Canal System: A Multistep Technique

Contemporary Cleaning and Shaping of the Root Canal System.

Prevention or treatment of apical periodontitis is aimed at disinfecting the root canal system so that the periradicular tissues are not vulnerable to attack from microbiota within the tooth. This is achieved by a process of cleaning and shaping the root canal space. The fundamental principles underlying this process have not changed in decades. In contrast, the armamentarium available to the c...

Preparation of the root canal system

The key factor in the development of pulpal inflammation and apical periodontitis is the presence of bacteria [42]. It has been widely accepted that bacteria and/or their products are the main aetiological factors in the initiation and progress of these diseases [10]. Consequently, the central focus of root canal treatment has been directed towards the elimination of bacteria and their substrat...

Root canal system of the maxillary canine.

To better assess the efficacy of mechanical preparation of root canals, transparent specimens of 250 extracted maxillary canines were investigated for canal configuration, thickness and curvature of the root canal, condition of any accessory canals, and location of the apical foramen. Fewer than 40% of the specimens showed accessory canals that were mechanically impossible to clean. The majorit...
