The present invention relates to a dental device for shaping and simultaneous flushing and suction of a tooth root canal, a head of a dental device for shaping and simultaneous flushing and suction a tooth root canal by shaping the tooth root canal and a hollow endodontic file for shaping and simultaneous flushing and suction a tooth root canal by shaping the tooth root canal.

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.

A dental bur for removing precise portions of a tooth includes a shank and a head. The shank includes first and second end, an attachment section located adjacent the first end, and a guide section located between the attachment section and the second end. The attachment section is configured to be inserted into and rotationally driven by a high-speed rotary device. The guide section includes at least one portion having a first width measured in a transverse direction of the shank and a second portion having a second width measured in the transverse direction. The first width being different than the second width. The head is arranged on the second end of the shank and includes a tip located opposite the shank. The tip has a rounded portion configured to remove portions of the tooth, and the head is entirely coated in an abrasive diamond material.

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.
