“…Diameter of the root canal has been studied earlier by passing a line through centre of the canal and parallel to mesiodistal and buccolingual plane in previous studies [ 5 , 13 , 15 , 18 ]. However, root canals are not circular in shape; in most instances, they may be oval, ribbon-shaped, or C-shaped [ 5 , 38 , 39 ]. Therefore, in the present study, rather than a diameter, MD and BL width of the canal were considered.…”

Background. A thorough knowledge of root and root canal morphology in primary dentition is essential for success of endodontic therapy. This information also finds importance in anthropological research in reconstructing human population history. Lack of studies of root and root canal morphology in mandibular anterior teeth prompted us to the present study. Methods. A total of 109 extracted primary mandibular incisors and canines were collected, out of which 90 teeth were selected for this study and divided into 3 groups: CI, mandibular central incisor; LI, mandibular lateral incisor; C, mandibular canine. All the sample teeth were scanned using cone beam computed tomography (CBCT). Number of roots, number of root canals, length of root, mesiodistal (MD), and buccolingual (BL) width of canal, shape of canal, and presence of accessory canals were assessed. Collected data were statistically compared using one-way ANOVA and chi-square tests. Results. All teeth studied displayed single root with single root canal conforming to type I Vertucci’s classification. Root length of CI was significantly shorter than both LI and C, with no significant difference between LI and C. Straight root canals were more common in CI and LI, whereas curved canals were more common in C. S-shaped canals were seen in a few CI and C. BL canal width was more than MD width in all teeth, C showing significantly larger dimensions than both CI and LI. Conclusion. This study presents root and root canal characteristics of primary mandibular central incisor, lateral incisor, and canine in children from Indian ethnicity.

Knowledge of root and canal morphology is essential for the effective practice of root canal treatment. Paediatric endodontics aims to preserve fully functional primary teeth in the dental arch; however, pulpectomy procedures in bizarre and tortuous canals encased in roots programmed for physiologic resorption are unique challenges. A new coding system for classifying the roots and main canals (https://doi.org/10.1111/iej.12685), accessory canals (https://doi.org/10.1111/iej.12800) and developmental anomalies (https://doi.org/10.1111/iej.12867) has been introduced recently. This paper discusses challenges for describing root and canal morphology in primary teeth and describes the potential application of the new classification system for root canals in the primary dentition.

“…Root canal treatment or partial pulpectomy has become part of the routine treatments of primary teeth. To ensure normal physiological resorptive process and exfoliation, or if tooth retention is required for some time, and to optimize these procedures, it is necessary to realize the anatomy of these root canal miniatures, with all associated anomalies and fine communications, just like in permanent teeth (59)(60)(61)(62)(63). Root canal treatment in primary teeth has challenged with many factors, signing first one which is aberrance from normal morphology specially in the posteriors, as a result of dentin islands formed continuously, in addition to physiologic resorption that may alter the working length, moreover anterior primary teeth normally show additional canals specially in upper canines.…”

Background: Morphology of the root canal system is divergent and unpredictable, and rather linked to clinical complications, which directly affect the treatment outcome. This objective necessitates continuous informative update of the effective clinical and laboratory methods for identifying this anatomy, and classification systems suitable for communication and interpretation in different situations. Data: Only electronic published papers were searched within this review. Sources: “PubMed” website was the only source used to search for data by using the following keywords "root", "canal", "morphology", "classification". Study selection: 153 most relevant papers to the topic were selected, especially the original articles and review papers, from 1970 till the 28th of July 2021. Conclusions: This review divided the root canal analysis methods into two approaches; clinical and in vitro techniques. The latter has shown more precise non-subjective readings, on the other hand; the clinical methods provide direct chair side diagnosis for the clinical cases. The classification systems reviewed in the present study, started with the oldest trials that simply presented the root canal systems, according to the degree of angulation, or by coded Latin numbers or English letters. Then, the most recent systems were also presented that were persisted with continuous editions up to date. These new systems could briefly describe the root and root canal’s internal and external details in a small formulation, without confusion and in an easily communicated manner, highly recommended specially for students, teachers, and researchers
