Description

Studies on the anatomy and morphology of the apical part of the tooth root canal present a significant area of interest and challenge for endodontists. Research indicates that the position of the apical constriction, apical foramen, and the cementdentin border varies from tooth to tooth. These anatomical reference points are considered as boundaries for the instrumentation and obturation of the root canal. Achieving an optimal working length is essential for successful root canal treatment, and reaching or failing to reach any of these reference points is associated with specific risks and benefits. Clinically, the positions of the apical constriction and apical foramen can be detected, while the cement-dentin border poses a challenge as it represents a histological boundary that cannot be clinically identified. The radiographic apex does not always coincide with the anatomical apex of the tooth. Analyzing radiographic data prior to endodontic treatment, along with literature data obtained through other examination methods, should be considered when determining working length. Most researchers agree that a filling border 2-3 mm below the radiographic apex is associated with favorable treatment outcomes. Our studies focus on analyzing literature data and our findings regarding the success of reaching the apical constriction using either warm or cold gutta-percha obturation techniques.
