Influence of anatomical features in the endodontic treatment planning of maxillary anterior teeth

Abstract

This study evaluate the maxillary anterior teeth anatomy by micro-computed tomography (μCT), about relevant characteristic for endodontic treatment planning. Fifty maxillary central incisors (MCI), lateral incisors (MLI) and maxillary canines (MC) were scanned using a μCT device. Two and three-dimensional parameters at 1 to 5mm distance to the apical foramen, external anatomic characteristics of the teeth and qualitative analysis of the internal anatomy was performed. The roundness and form factor values revealed a circular canal in the apical third in the MCI and MC, whereas MLI showed flattening in the apical third. The linear regression test indicated a progressive increase in the major/minor diameters in the five mm assessed (p < 0.001). The 3D analysis revealed the greatest volume and surface area in MC. The SMI showed a cylindrical geometry of root canals. All teeth presented Vertucci's type I root canal configuration. A mild curvature was prevalent in the MCI (45%) and a moderate one in the MLI (50%) and MC (50%). Palatal shoulder volume was smaller in the MLI (11.46 ± 3.09) than in the MCI (14.15 ± 3.85) and MC (13.95 ± 2.55). The most common exit of main apical foramen was in a central (22%), distolingual (30%) and mesiobuccal position (28%) for MCI, MLI and MC, respectively. Radicular grooves were observed in 2% of MCI and 4% of MLI. Two and three-dimensional data obtained by μCT allowed to observe morphological characteristics of internal/external anatomy of the maxillary anterior teeth. These characteristics may affect the endodontic treatment planning.

Evaluation of Feline Permanent Canine Tooth Mineral Density Using Micro-Computed Tomography

“…However, the fact that it allows acquisition in a wet state allows the future processing of teeth for histological analysis. Furthermore, the possibility of data storage allows the future reanalysis of morphological features of interest [ 29 ], using other specific algorithms, reducing the need to collect new samples for similar tests.…”

Challenges Assessment in Endodontics Among Undergraduate Students

“…It plays a crucial role in preserving natural teeth, preventing the spread of infection, and maintaining oral health. The prerequisites for successful endodontic treatment comprise a thorough understanding of the normal and variant root canal anatomy [1], the ability to interpret radiographs and other diagnostic images, sound clinical decision-making skills, diagnosis of pulpal and periapical diseases, appropriate treatment planning and proper execution of each step of the root canal therapy including isolation, administration of anesthesia, access cavity preparation, working length determination, canal shaping and disinfection, obturation and placement of the coronal restoration [2,3]. An error occurring at any point in these steps can result in endodontic treatment failure [4,5].…”
