A root canal treatment device relates to the technical field of dental treatment instruments. The root canal treatment device comprises a contra-angle hand-piece (10) and a root canal file (20) detachably connected to the contra-angle hand-piece (10), and further comprises a drive module (30) in transmission connection with the root canal file (20), the drive module (30) comprises a rotation driver (31) and a vibration generator (32), wherein the rotation driver (31) is configured to drive the root canal file (20) to rotate axially, so as to mechanically cut and ream the root canal, thus shaping the root canal, and the vibration generator (32) is configured to drive the root canal file (20) to vibrate radially. Vibration of the root canal file (20) at a specific frequency can sufficiently activate the activity of the drug material filled in the root canal, especially in the process of filling the drug material into the root canal, the vibration provided by the vibration generator (32) and the rotation of the root canal file (20) that are carried out simultaneously can efficiently discharge the air bubbles in the drug material filled in the root canal, so that the drug material can be tightly filled into the root canal, thereby providing a better environment for subsequent root canal treatment, improving the effect of root canal treatment, and relieving the patients' pain.

According to an embodiment, a painless syringe for reducing noise and friction caused when perforating an alveolar bone comprises an injecting part having a needle for perforating the alveolar bone and injecting an anesthetic, a holder having a first end coupled with the injecting part and a second end open and empty, an ampoule formed to be inserted into the holder and having a first end into which the needle of the injecting part is inserted and a second end having a piston for discharging the anesthetic, a housing formed to receive the holder and having a through hole to expose the first end of the holder to an outside, and a handpiece coupled with the housing, rotating the ampoule, the holder, and the injecting part to perforate the alveolar bone, and pressing the piston to inject the anesthetic.

A device for detaching a tooth root. The device comprises: a lead screw having a threaded point for screwing into the tooth root, and a threaded shaft; a pivoting member including a bore through which the lead screw passes, the lead screw being retractable through the bore by rotational engagement of a threaded member with the threaded shaft of the lead screw; and a platform for supporting the pivoting member such that the lead screw is able to pivot relative to the platform, The lead screw includes a locking surface for preventing rotation of the lead screw during rotational engagement of the threaded member with the threaded shaft.

A custom drill guide and a method, system, and computer readable media for determining a number and location of canals in the tooth in order to create a custom drill guide to match the anatomy for proper orientation of high speed burs and files for cleaning/shaping. By knowing where the canals are located within the tooth, a relatively small access opening may be created, the small access opening provides for a strong crown during the restoration process.

Dental treatments and methods, including treating gum disease, using peroxide gel and a viscous antibacterial agent including tetracycline to chemically debride and curettage a treatment area. Treatments and methods include non-surgically scaling and root plaining the treatment area with dental tools such as periodontal scalers and/or curettes during the active period of the chemical debridement. The working surfaces of dental tools can be sharpened for optimal root and tooth surfacing during treatment. Treatment can include instructions for co-therapy by or on behalf of treatment subjects between visits and for maintenance care.
