Dental hygiene and periodontal hand instrumentation requires alignment of the cutting surface of the instrument at a specific angle and adaptation to the tooth surface. A dental hygiene and periodontal hand instrumentation tutor provides an objective, consistent and accurate way to measure and display the actual angulation and adaptation angles of a periodontal hand instrument and assess instrument use continuously. The method includes detecting the position, orientation, motion path, pressure, angulation angle, adaptation angle, and centerline angle of a periodontal hand instrument and comparing them to ideal positions, orientations, and motion paths; and provides various forms of user feedback.

A tooth whitening kit and method of whitening teeth using the same. The method may include applying a tooth whitening composition directly to surfaces of a user's teeth, exposing the surfaces of the user's teeth to ambient air for a first period of time to form a film of the tooth whitening composition on the surfaces of the user's teeth, applying light to the surfaces of the user's teeth for a second period of time while the film of the tooth whitening composition remains on the surfaces of the user's teeth, ceasing application of the light to the surfaces of the user's teeth and leaving the film of the tooth whitening composition on the surfaces of the user's teeth for a third period of time, and removing the film of the tooth whitening composition from the surfaces of the user's teeth.

The present disclosure is directed to tools, systems and methods for recontouring/reshaping gum tissue by engaging a consumable tip on a powered tool to abrade/ablate excess or mal-contoured gum tissue to allow better visualization of the tooth/implant structure and reduce the periodontal pockets to provide improved access for cleaning by both the patient and clinician. In some embodiments, the powered tool may use vibrational movement, longitudinal reciprocating movement, rotational movement, reciprocating rotational movement, or a combination of any of the above movement schemes. In some embodiments, a consumable tip may be directed for cleaning tooth/implant surfaces and for recontouring/reshaping gum tissue. The powered tool itself may be constructed to allow the cooling water flow used for operation to be directed to the site where the procedure is carried out for irrigation or to be directed elsewhere at the user's selection to facilitate gum contouring procedures.

A toothbrush for promoting plaque removal, and a manufacturing method therefor are proposed. The toothbrush includes: a head part in which elements for cleaning teeth are arranged; a first electrode on the head part; a second electrode on the head part, the second electrode being spaced a predetermined distance from the first electrode and grounded; and a voltage supply part configured to superpose alternating current (AC) voltage and direct current (DC) voltage and apply the AC voltage and the DC voltage together to the first electrode.

Provided herein are methods of using multipotent stem cells in treatment or prophylaxis of disease, in a system for improving general health and overall wellness. The disclosure provides a method in which multipotent stem cells are intravenously administered within the oral cavity, which has a rapid effect on symptoms of inflammation and/or infection, not only treating periodontal diseases, but also reducing bacterial load, pain, bone loss, etc. as well as stimulating new bone growth and achieving other hallmarks of improvement in health and overall systemic wellness. In some instances, a sample of a bodily fluid is drawn from the patient before injection to measure baseline levels of several biomarkers to obtain the patient's status on the spectrum of health and wellness and/or to compare post-treatment effects of the injected stem cells, to measure improvement, and to develop a treatment plan for enhancing multisystem wellness.

An aqueous solution for intraoral cleaning via irradiation with ultraviolet ray and/or near-ultraviolet visible ray and/or ray in an 800-900 nm near-infrared region is employed as the hydrogen peroxide aqueous solution, wherein a concentration of hydrogen peroxide is 1 w/v % to 7 w/v %, and a concentration of a hydrogen peroxide stabilizer is 81 ppm (mg/L) or less in the aqueous solution.

Periodontal disorders such as disorders associated with a dental implant are treated. An average power for a laser is selected via a user interface on a tablet, along with a set of permissible laser parameters provided in response to the selected average power. A gingival trough or flap is created around the implant with the laser. Infected tissue is selectively ablated or denatured via photothermolysis, and a pocket is lased around the affected implant. Marginal tissues are compressed against the implant.
