Apparatuses and methods are provided for displaying the position of a dental file during endodontic treatment. Data showing the morphology of a tooth is obtained. In one embodiment, the data is X-ray image data. A three-dimensional representation of the dental file positioned in the tooth is generated, and a length that the dental file extends from an upper surface of the tooth is determined from the three-dimensional representation. A representation of the dental file is provided in the image of the tooth obtained from the data showing the tooth morphology, with the representation of the dental file being depicted such that a part of the representation of the dental file extends from the upper surface of the tooth in proportion to the length that the dental file extends from the upper surface of the tooth as determined from the three-dimensional representation and such that a remaining part of the representation of the dental file extends into the tooth, with a part of the remaining part of the representation of the dental file being positioned in the root of the tooth in the image. The image of tooth and representation of the dental file may be displayed.

The demand for biocompatible dental materials has increased significantly, particularly in vital pulp therapy, due to the need for materials that promote tissue regeneration and long-term success. This invention introduces a novel Nanocarbon Platelets-Enhanced Portland Cement Composite that combines the well-established properties of Portland cement with the advanced mechanical and biological characteristics of graphene oxide nanocarbon platelets. This composite is designed to serve as both a restorative material and an agent for vital pulp therapy. The integration of graphene oxide nanocarbon platelets enhances the composite's mechanical properties while maintaining superior biocompatibility. This ensures the material supports cell viability and proliferation, crucial for successful tissue integration and regeneration. The unique formulation also improves the sealing ability of the cement, providing exceptional protection against bacterial infiltration and aiding in the preservation of dental structures. This invention aims to address the limitations of existing Portland cement-based materials, such as weak mechanical properties and potential cytotoxicity, by offering a more robust and biocompatible alternative. The composite is developed with a specific focus on dental applications, ensuring it meets the demands of modern restorative and endodontic procedures. The Nanocarbon Platelets-Enhanced Portland Cement Composite offers a cost-effective solution that can be easily integrated into existing clinical practices. Its development represents a significant advancement in materials science, with potential applications beyond dentistry, such as in orthopedic and craniofacial reconstruction. This composite sets a new standard for dental materials by combining mechanical strength, biocompatibility, and ease of use, promising improved outcomes for both patients and practitioners.

This invention belongs to the field of endodontics, specifically relating to a simulated dental jaw model for the entire process of endodontic treatment. It includes a maxillary model, a maxillary base, a maxillary joint, a mandibular model, a mandibular base, a mandibular joint, a connecting device, a cervical joint, and a tail fixation device. The mandibular model includes a mandibular shell, a movable micro-adjustment module, and an extracted tooth. The mandibular shell is filled with a water-absorbing gel-like material. The movable micro-adjustment module is detachable. This invention allows for the rapid fixation and replacement of extracted human teeth, and can also recreate the adjacent relationships, periodontal microenvironment, and moist conductive environment around the tooth root. It can highly simulate the physiological conditions of extracted teeth within the dentition and jawbone, and is suitable for various teaching and training programs in endodontic microsurgery, dental restoration, and microsurgical root canal treatment, greatly expanding its application scenarios.

FIELD: dentistry.SUBSTANCE: intended for practicing manual endodontic treatment skills in students to improve the effectiveness of treating diseases of the periapical tissues of teeth. A phantom simulation model of a tooth with external root resorption is used, which includes a 3D-printed model of a tooth with a root canal having a hemispherical expansion at the root apex. In this case, the phantom simulation model of the tooth is made of transparent or radiopaque photopolymer resin, has a length of 30 mm with a red-colored canal system of 15 mm in length. In this case, the transparent model of the affected tooth is intended for the initial level of manual skill, and the opaque radiopaque model of the affected tooth is intended for the process of training in endodontic root canal treatment, where quality control of treatment and filling of root canals is possible only by radiographic method. In this case, the root apex has a size of No. 80 according to ISO, and the hemispherical expansion at the root apex of the tooth model, simulating a chronic lesion of the periapical tissues of the tooth, has a diameter of 8 mm. In this case, using Blue Sky Bio software, a three-dimensional image of the affected tooth is extracted from the patient's cone-beam computed tomography (CBCT) scan in DICOM format, then, using artificial intelligence algorithms in Blender software, the model is corrected, virtually modeling a tooth with a root cyst and external resorption. After this, the model is imported into STL format, 1.9 ml of resin is collected for subsequent slicing and 3D printing, and the walls of the root canal system of the resulting model are painted red with Funtodo photopolymer resin.EFFECT: inventions, by simulating endodontic treatment training conditions that are as close as possible to real conditions, namely, an apical plug in the area of the wide apex of a tooth root during inflammatory external resorption or after apical resection, allow for the practice of existing variations of endodontic treatment, and also minimize the time costs for model production.3 cl, 14 dwg, 1 ex

The present invention relates to a nickel titanium (Ni-Ti) file for use in all fields of dentistry, including root canal therapy (endodontic applications), and in patient treatment procedures associated with root canal therapy. The Ni-Ti file is designed to remove filling residues, pulp and other residual materials from the root canal during pulp treatment.
