In one aspect, embodiments relate to a system for preventative dental laser treatment that ensures even irradiation of a laser beam. The system includes, a laser arrangement configured to generate the laser beam. The laser beam has one or more of a super-Gaussian energy profile and a transverse ring mode. The system also includes a focus optic. The focus optic is configured to converge the laser beam with a numerical aperture of 0.1 or less to a focal region. The system also includes a hand piece configured to direct the laser beam at a surface of a dental hard tissue. The system additionally includes a controller. The controller is configured to control one or more parameters of the laser source, such that a portion of the surface of the dental hard tissue is heated to a temperature in a range between 400° Celsius and 1300° Celsius.

An electric field generating device for oral care of the present invention includes: at least one electrode configured to receive a driving signal and generate an electric field corresponding to the driving signal; and a signal supply part configured to generate the driving signal by mixing an AC signal and a DC signal and supply the driving signal to an electrode.

The present invention relates to a disposable dental appliance and, more particularly, a dental prophy angle used for cleaning and polishing teeth, especially, a prophy angle for holding a disposable polishing/cleaning cup-head/brush-head that is disposed after each application to a patient to prevent potential cross contamination. The disposable prophy angle for a handpiece preferably comprises an elongated tubular housing, a drive shaft, a driven gear rotor, and a prophy cup/brush-head. The tubular housing has a longitudinal and a transverse section in one integral piece with a proximal end adapted to couple to a standard dental handpiece. The housing further has an extrusion-molded socket on its top inner surface. The housing has a horseshoe-like locker to position the drive shaft gear against the driven rotor gear. The driven rotor comprises a rotor head, a rotor neck, a driven rotor gear, a cup flange, a cup neck, and a cup holder.

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 angled-head rotary cleaning device for dental purposes includes a plastic housing having an elongated neck portion that defines a sleeve with a wall. The neck portion includes a first end and a second end. The plastic housing has a head portion coupled to the first end of the neck portion and angled relative to the neck portion. The cleaning device also includes an elongated light guiding element having a light entry portion to receive light, and a light exit portion to emit light. At least a portion of the light guiding element is accommodated within the wall of the neck portion.

A meso-abrasive dentifrice formulation of from 15 wt % to 30 wt % a first abrasive, from 10 wt % to 15 wt % a second abrasive, and excipients. The second abrasive is silica and is different from the first abrasive. A system is also disclosed for cleaning a human oral cavity having the disclosed meso-abrasive dentifrice formulation and an oscillating cup for delivery of the dentifrice formulation. The system demonstrates a Cleaning Efficiency Index (CEI) of from 2.34 to 2.45. The system demonstrates an Increase in Gloss Score of greater than 28 and a system Relative Dentin Abrasiveness (RDA) value less than 100.

In some embodiments, a periodontal instrument comprises an end including a functional shank and a working end located distal to the functional shank, and a handle configured to extend proximally from the end, the handle sized and configured to be received by a user's hand. The functional shank may include a colored portion, and the colored portion may define a terminal shank of the functional shank. In some embodiments, the colored portion is configured to aid the user in identifying the terminal shank.

In one aspect, embodiments relate to a system for preventative dental laser treatment that ensures even irradiation of a laser beam. The system includes, a laser arrangement configured to generate the laser beam. The laser beam has one or more of a super-Gaussian energy profile and a transverse ring mode. The system also includes a focus optic. The focus optic is configured to converge the laser beam with a numerical aperture of 0.1 or less to a focal region. The system also includes a hand piece configured to direct the laser beam at a surface of a dental hard tissue. The system additionally includes a controller. The controller is configured to control one or more parameters of the laser source, such that a portion of the surface of the dental hard tissue is heated to a temperature in a range between 400° Celsius and 1300° Celsius.

The invention relates to a dental tool having a shank region, which is formed for coupling to a dental handpiece, and also having a work region, which is connected to the shank region. In this case, the shank region of the dental tool is formed so that there is the possibility of latchable insertion and removal without actuation. In particular, at least the shank region can consist of plastics material. As a result, inter alia facilitated handling of the tool and inexpensive production of the tool are rendered possible.
