Today, we’ll explore tooth anatomy, focusing specifically on the challenging C-shape canal often encountered in endodontic treatment.
The Dental Master series began with the study of tooth internal structures. Its first step was the 2001 research on maxillary molar canal curvature, during which we created a 3D tooth model. This model has since become an invaluable resource, not only as a research tool but also as a way for students and clinicians to visualize the internal anatomy of teeth—something that's often difficult to grasp during practice or patient treatment.
In endodontics, most clinical challenges arise from the unique structure of each tooth. If we can preemptively understand the tooth’s internal anatomy and canal structure, we can address many complications in the treatment process, leading to improved clinical outcomes.
Dental EndoMaster was developed to visually demonstrate complex internal tooth structures that can’t be easily observed during clinical practice or standard training. We continue to add new tooth models and enhance the app, ensuring it remains a valuable resource for improving endodontic skills.

One of the upcoming updates will feature the C-shaped canal in mandibular molars. C-shape canals are commonly found in Asian populations, where the root has a C-shape configuration, and the canal follows this thin fin-like structure. Unlike cylindrical canals, it’s much more challenging to clean the canal walls using a round rotary file due to this unique shape.
The canal shape, viewed from different angles, shows that the ML canal runs independently, while the others are connected by a thin fin-like structure extending from the orifice to the apex
The cross-sectional shape from the orifice to the apex shows that the canals are connected by a thin ribbon-like structure at each section.
The canal orifices of the mesio-lingual, buccal, and distal canals are observed.
In conclusion, understanding complex canal anatomy, such as the C-shape configuration, is crucial for successful endodontic treatment. Dental EndoMaster allows you to visually explore and practice these challenging cases before facing them in the clinic. Stay tuned for our upcoming update, where you'll have the chance to experience the intricacies of C-shape canals, enhancing your knowledge and clinical confidence.
