Examples of apparatus, methods, and compositions for endodontic treatments are described. The apparatus can include a fluid platform configured to substantially retain fluid in a tooth chamber during treatment. The fluid platform can help maintain fluid circulation in the tooth chamber as fluid flows into and out of the tooth chamber. The apparatus can also include a pressure wave generator configured to generate acoustic waves that can be used for cleaning root canals and tooth surfaces in the tooth chamber. Examples of pressure wave generators include a liquid jet, an electromagnetic energy delivery device, and an ultrasonic device. The fluid can include antiseptic or antibacterial solutions to assist in tooth cleaning. The fluid may be degassed to have a reduced dissolved gas content (compared to non-degassed fluids used in endodontic treatments), which may improve the effectiveness of the pressure wave generation or the cleaning.

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 provides a structured, biologically based clinical method for mitigating symptomatic pulpal conditions and preventing unnecessary endodontic treatment. Targeted at teeth with vital pulps and reversible inflammation, the protocol combines selective caries removal, pulp protection using calcium hydroxide or MTA, a sedative zinc oxide-eugenol base, and provisional sealing with moisture-setting cement. The method includes diagnostic, therapeutic, and follow-up steps, with one-week, one-month, and three-month evaluations to assess healing. If symptoms persist, root canal therapy is initiated; if asymptomatic, definitive restoration is performed. Annual monitoring ensures long-term pulpal stability. This reproducible approach prioritizes pain control, infection management, pulp preservation, and tooth longevity. It provides an evidence-based alternative to conventional endodontics, reducing overtreatment while supporting functional and biological integrity of the dental organ.
