“…The complex root canal anatomy of primary molars together with variable features of file systems originally developed for permanent teeth may have caused this outcome in primary molars . This opinion is consistent with the findings from a previous study which revealed the complexity of the primary root canal morphology and the need for the development of rotary instruments for primary root canal treatment . Although Revo‐S obtained the best results for the primary dentition among all files tested, 60% of root canal surface was still left uninstrumented after preparation.…”

“…28 This opinion is consistent with the findings from a previous study which revealed the complexity of the primary root canal morphology and the need for the development of rotary instruments for primary root canal treatment. 31 Although Revo-S obtained the best results for the primary dentition among all files tested, 60% of root canal surface was still left uninstrumented after preparation. Again, this unsatisfactory outcome can be explained by the complex root canal anatomy of primary molars, which consists of anastomoses, lateral canals, and accessory canals within and between the main roots.…”

Background Root canals of primary teeth are commonly prepared with endodontic files that are originally manufactured for permanent teeth. Aim This micro‐computed tomography (micro‐CT) study evaluated and compared the changes in root canal morphology after preparation with different conventional and rotary files in primary teeth and young permanent teeth. Design Seventy‐two extracted primary and permanent molars were selected and randomly assigned to three subgroups according to the file systems used (n = 12/each). After pre‐scanning of teeth with micro‐CT, root canals were prepared with One Shape and Revo‐S rotary systems and conventional endodontic files. After rescanning procedure, changes in canal volume, surface area, uninstrumented surface area, and apical transportation were evaluated. Mann‐Whitney U test, Kruskal‐Wallis test, and Conover's multiple comparison test were used for statistical analysis (P = .05). Results Instrumentation with rotary files resulted in significantly greater volume and surface area of root canals and less uninstrumented areas (P < .001) than with manual files (P < .001). Primary molars showed significantly less apical transportation than permanent teeth (P < .001). Conclusions Preparation of canals with rotary files could be a viable alternative to conventional files in primary teeth. Regardless of the file system used, uninstrumented areas still exist in both primary teeth and permanent teeth.

“…One micro-CT study reported that approx. 83% of extracted primary molars had a least one accessory canal in the furcation area (chamber/furcation canals) (Berscheid 2015), whilst another reported that all mesial and distal roots of primary second mandibular molars had lateral canals (El Hachem et al 2019). It is worth noting that only a small number of those canals are patent, and the majority usually terminate within the root dentine (Berscheid 2015, Sharma et al 2016.…”

“…Pulpectomy procedures in primary teeth aim to ensure normal physiologic exfoliation and eruption of the successor tooth or their long-term survival when their retention is required. Root and canal morphology in the primary dentition has a wide range of anatomical variations and is unpredictable (Ahmed 2013, Ozcan et al 2016a, Reddy et al 2018, Neboda et al 2018, El Hachem et al 2019.

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.
