Dental scalers are used to remove plaque buildup and calculus from teeth. Traditionally, dentists have used simple scaler instruments to manually remove plaque and calculus from a patient's teeth. More recently, ultrasonic dental scalers, which utilize a tip that vibrates or oscillates at high speeds, typically ultrasonic speeds, have been developed. The ultrasonic dental scaler tip is applied to a tooth and the tip's oscillations remove the plaque and calculus buildup from the tooth. With existing dental scalers, a base unit is used to control both the intensity of the tip's oscillations and the water flow, for cooling purposes, from a nozzle in a tip portion of the handpiece that includes the tip. However, this arrangement requires the dental scaler operator to turn away from a patient to adjust the volume of water flow or power to the scaler, resulting in taking the focus away from the job at hand and leading to imprecise adjustments of the controls, and poor experience for both the operator and the patient. Foot operated pedals and similar controls have also been considered. However, cabled versions of these pedals are difficult to reposition during therapy if, for example, the operator needs to change positions relative to the patient and can present an entanglement and trip hazard even where repositioning is not required. Further, wireless pedal controls must be frequently charged and synchronized with a scaler base unit transceiver, which can also complicate set-up and operation.
According to one aspect of the disclosed subject matter, an ultrasonic dental scaler comprises a handpiece and a base unit. The handpiece includes a tip portion that includes a tip and a nozzle for providing or spraying water to the tip for cooling purposes. The handpiece is coupled to the base unit and configured to provide power to the tip portion which, in turn, causes the tip to oscillate. Additionally, the handpiece includes a user-manipulable control that controls an amount of water provided to the tip portion for cooling. Placing a user-manipulable control on the handpiece to control the amount or volume of water used to cool provides a better experience for the operator and the patient.
Alternatively, or in addition thereto, the handpiece itself may include a user-manipulable control that controls the intensity of the tip oscillation, thereby affording convenient operation of the dental scaler from the handpiece. Also, the handpiece may optionally include a power switch to turn the dental scaler system off or on.
The disclosed subject matter also includes a treatment method which utilizes a dental scaler handpiece that includes both an oscillation intensity or power level control unit and a water flow rate control unit on or as part of the handpiece.
Another aspect of the disclosed subject matter is directed to a root beer infused dental floss created by placing dental floss in a substantially liquid root beer concentrate for a period of time based on the absorbency of the dental floss material and desired degree of flavor. The root beer concentrate may be formed by combining substantially equivalent portions of sarsaparilla, sassafras, licorice root and burdock root.

In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical items or features. In some instances, well-known methods, procedures, and components have not been described in detail to avoid obscuring the embodiments described.
The following describes an ultrasonic dental scaler that includes a base unit and a handpiece, formed in accordance with aspects of the disclosed subject matter. The handpiece comprises a barrel portion and a tip portion, where the tip portion includes a tip that, when powered, oscillates. The tip portion further comprises a nozzle for spraying water on the tip, for cooling purposes. The barrel portion of the handpiece is typically, though not exclusively, a slender object. The barrel portion may be, by way of illustration and not limitation, triangular, oval, rectangular, cylindrical, or some other shape that it can be easily held by an operator and used for inserting and manipulating the tip portion in the mouth cavity of a patient for cleaning. The handpiece further comprises a first user-manipulable control, i.e., a water flow control, which controls the volume of water sprayed by the nozzle to cool the tip. This water flow control may, in some embodiments, incorporate a barrel-mounted dial to permit easy adjustment of the water flow rate without the operating oral care provider from having to turn away from the patient. In some embodiments, the handpiece may further comprise a second user-manipulable control that controls the intensity of the oscillations of the tip, as described later in this section.
Traditionally, dentists and other oral healthcare professionals have utilized simple dental scaler instruments to remove plaque and calculus from a patient's teeth. More recently, however, ultrasonic dental scalers have been developed. The ultrasonic dental scaler tip is applied to a tooth and the oscillations of the tip cause the plaque and calculus buildup to be removed from the tooth. In existing solutions, a foot manipulated base unit is used to control both the intensity of the tip's oscillations and the water flow volume from tip. However, manipulating the controls of the base unit requires the dental scaler operator to turn away from the patient to adjust the water flow and/or power to the scaler, resulting in taking the focus away from the job at hand and leading to imprecise adjustments of the controls, and poor experience for both the operator and the patient.
In the illustrated embodiment shown in
Also shown in on handpiece 104 are plural raised bump grips 120 to allow the oral care provider's hand to firmly grasp and manipulate the handpiece 104.
In the illustrated embodiment, the base unit 101 includes a user-manipulable power level control 111 that, in some non-limiting embodiments, may be a dial. Here, the dial is substantially circumscribed by a ridged edge ring 121 made of a transparent material. This transparent ring 121 can be illuminated by e.g. an LED, LED array or other suitable light pipe guiding light from a light source (not shown) within the base unit 101to selectively highlight the current dial setting. The base unit 101 also includes a connection 108 to a power source such as a power cord and a water supply line 109 from the water mains. The base unit 101 supplies power to electronic components of the dental scaler handpiece 104 which, in turn, delivers power to the tip 105 causing oscillations and enabling water to be sprayed from a nozzle 106 to cool the tip.

With the illustrated embodiment, when operating the dental scaler system 100, an operator removes plaque and calculus from a tooth by touching the tip 105 to the plaque and calculus on the tooth surface.
As those skilled in the art will appreciate, the high frequency oscillations of the tip 105 may cause the tip to heat up. The operator cools the tip by controlling the flow of water provided by the coupling 102 to the nozzle 106 which may be located on or near the tip 105. The volume of water used for cooling the tip 105 may be controlled by a water flow control unit 103 which, advantageously, is also located on the handpiece 104. Though not intended to be limiting the teachings of the disclosed embodiments, this water flow control 103 may include, for example, a handpiece barrel mounted water lavage control assembly provided with the Cavitron Select SPS Ultrasonic Scaler from Dentsply Sirona of Charlotte, N.C. As the heat increases on the ultrasonic dental scaler tip 105, perhaps from extended use, the operator may increase cooling of the tip by increasing the water flow to the tip 105 via manipulation of the water flow control, and as the heat decreases, the operator may decrease the water flow to tip 105 via manipulations of the water flow control. The base unit is shown to include a power switch 110 that serves as an on/off control for the ultrasonic dental scaler system 100.
Another problem with existing dental scalers where the power-level is adjusted via a foot control is that if the operator wants to control the amount of power supplied to the tip, i.e., wishes to control the intensity of oscillations by the tip, the operator must stop the treatment, turn away from the patient and adjust an appropriate control, e.g., a dial, on the base unit. This takes the focus away from the patient and may result in imprecise adjustments to the power level. To remedy this problem, we refer to the embodiment shown in
According to additional aspects of the disclosed subject matter a dental laser system 400 (
As with the dental scaler handpieces 104, 204 and 304 described above, the periodontal laser handpiece 406 includes bump grips 420 to help the oral care provider grasp and manipulate the handpiece 406 during treatment.

Although the previous embodiments describe the water flow rate and power level/intensity controls in terms of adjustable or twistable dials, one or more other types of selector mechanisms can be interchangeably provided, including one or more multi-position or overloaded buttons, sliders and/or the like on the dental scaler or laser handpiece so long as they can provide settings feedback to the operator and can be manipulated without having to turn away from the patient.
At step s815, a determination is made by e.g. a treatment provider whether the dental scaler 300 is set at the correct oscillation intensity or power level for the scaler tip. In this embodiment, the treatment provider can look at the current setting on control unit 305 dial on the handpiece 304. If the setting is incorrect, the method progresses to step s820, where the treatment provider adjusts the power level/intensity setting on the scaler handpiece 304 using the control unit 305 dial. Once adjusted to the correct setting, the method progresses to step s825. If, however, in step s815, it is determined that the correct power level/intensity is already set, the method instead jumps to step s825.
At step s825, a determination is made e.g. by the treatment provider whether the dental scaler system 300 is set at the correct water flow rate. In this embodiment, the treatment provider can assess the current water flow rate from viewing the current position or state of the water flow rate control unit 103 (dial) on the handpiece 304. If the water flow rate control unit is not correctly set, the method progresses to step s830. At step s830, the treatment provider adjusts the water flow rate control unit 103 settings on the handpiece 304. Once the correct water flow rate is set, the method then progresses to step s835. If, however, in step s825, it is determined that the water flow rate is correct, the method instead jumps to step s835.
At step s835, the treatment provider switches on the power to the tip using, in this embodiment, switch 205 shown in
At step s850, a determination is made whether treatment should continue (such as treating another tooth). If so, the method jumps back iteratively to step s805. If, however, treatment is completed or otherwise stopped, this treatment method ends.
Note that although it is contemplated that in this embodiment, for example determining steps s805, s815, s825 and s850 shown in
A further embodiment of the disclosed subject matter is directed to natural root beer infused dental floss. This floss involves dental floss (e.g. polyester and/or cotton filaments) soaked in a unique substantially liquidous root beer concentration as described below for approximately one (1) hour. In other embodiments, this soaking time may be longer or shorter based on e.g., the desired infusion of the root beer concentrate, the absorbency of the dental floss material. Once soaking is complete, the root beer “flavor” of the dental floss can be maintained by coating the treated dental floss with coconut oil.
The root beer concentration used here involves the following:
Ingredients: 4½ cups water, 1 large thumb of thinly sliced ginger root, 2½ tbsp of sarsaparilla, 2½ tbsp of sassafras, 2½ tbsp of licorice root, 2½ tbsp of burdock root, 1 tbsp of dried mint leaves, 1 star anise pod, 1 vanilla bean, and ½ cup of xylitol.
Instructions for making the root beer concentration: combine all ingredients except xylitol in a saucepan and bring to a simmer for 30 minutes. Thereafter, stir in xylitol until dissolved. Simmer this mixture on very low heat for an additional 30 minutes. Strain out the bits from the resulting mixture and retain the liquid. Then allow the liquid to cool to room temperature and refrigerate before use.
