DETAILED DESCRIPTION

[0042] Various terms used herein are intended to have particular meanings. Some of these terms are defined below for the purpose of clarity. The definitions given below are meant to cover all forms of the words being defined (e.g., singular, plural, present tense, past tense). If the definition of any term below diverges from the commonly understood and/or dictionary definition of such term, the definitions below control.

[0043] FIG. 1 is a perspective view of an exemplary brush device 100 and ultrasonic scaler 102. The ultrasonic scaler 102 includes a handle 104 and a removable cleaning tip 106 (e.g., insert) extending from a distal end 108 of the handle 104. The handle 104 includes a transducer (not shown) to convert electricity into mechanical energy at the cleaning tip 106. In some examples, the transducer may be magneostrictive or piezoelectric. The transducer vibrates the cleaning tip 106 at an ultrasonic frequency to induce a cavitation effect that may be used to clean teeth. The handle 104 may also have a coolant inlet line (not shown) to channel coolant (e.g., water) to the cleaning tip 106.

[0044] The cleaning tip 106 may include an elongated proximal end 110 that is configured to be received within the distal end 108 of the handle 104 and be secured therein. Opposite the proximal end 110, the cleaning tip 106 has a distal end 112 that is solid and configured to vibrate at high frequencies. In the example, the transition between the proximal end 110 and the distal end 112 of the cleaning tip 106 includes a coolant outlet 114 that is configured to channel coolant towards the distal end 112 and cool the end, as well as, provide the fluid for cavitation during operation. In the example, the distal end 112 includes a convex backside 116 and an opposite concave frontside 118. A lateral surface 120 extends from the backside 116 and terminates at a point 122. In other examples, the distal end 112 of the cleaning tip 106 may have any size and/or shape that enables the ultrasonic scaler 102 to function as described herein. It is appreciated that while one example of an ultrasonic scaler 102 and cleaning tip 106 is depicted in the figures, the brush device 100 as described herein may be used with any type of ultrasonic scaler 102 known in the dental field.

[0045] In operation, the lateral surface 120 may be the primary surface used for teeth cleaning and may vibrate either in a linear direction or an oval/circular direction. The cleaning tip 106 is typically formed from a metal material, which is undesirable to use with orthodontic appliances, crowns and bridges, dentures, and other dental work. As such, to clean implants and other dental work a plastic adapter 124 may be used. The adapter 124 may be substantially conical-shaped and include a first end 126 and a second end 128. The first end 126 has an opening 130 that extends towards, but not all the way to, the second end 128. The opening 130 is shaped to correspond to the distal end 112 the cleaning tip 106 so that the adapter 124 may be press fit thereon. The press fit frictionally secures the adapter 124 onto the distal end 112 such that high frequency vibration does not disengage the two components. To remove the adapter 124 a tool (not shown) may be used or it may be removed manually. The second end 128 of the adapter 124 may include a point 132 that is similar to the point 122 on the cleaning tip 106.

[0046] The point 122 of the cleaning tip 106 is relatively small (e.g., between 0.5 mm and 3 mm) and, as such, the lateral surface 120 may be required to make several passes over an area on the tooth to remove plaque and stain. Even with the adapter 124 secured over the point 122, the adapter 124 may still be required to make several passes for cleaning because it is not much larger in size than the distal end 112 of the cleaning tip 106. By having to make several cleaning passes along the tooth, streaks of plaque and stain may remain on the tooth and/or the amount of time needed for cleaning may be increased. Accordingly, the brush device 100 as described herein may be attached onto the cleaning tip 106 and be used to remove plaque and stain from teeth more efficiently.

[0047] The brush device 100 includes an insert housing 134 having an opening 136 to enable the brush device 100 to be press fit onto the distal end 112 of the cleaning tip 106. A base 138 extends about the insert housing 134 and supports a cleaning element 140 extending therefrom. In the example, the cleaning element 140 may include a tuft of bristles. By using bristles instead of the lateral surface 120 of the cleaning tip 106, the number of passes needed by the ultrasonic scaler 102 to clean a tooth decreases, thereby decreasing the cleaning procedure time. Additionally, residual plaque and stain streak marks along the tooth is decreased and/or eliminated. Furthermore, the bristles may be formed from a plastic-based material so that the ultrasonic scaler 102 may be used for cleaning implants and other dental appliances.

[0048] FIGS. 2A and 2B are side views of the brush device 100 coupled to the ultrasonic scaler 102. Referring concurrently to FIGS. 2A and 2B, to attach the brush device 100 to the ultrasonic scaler 102, the point 122 (shown in FIG. 1) of the cleaning tip 106 is inserted within the insert housing 134 of the brush device 100 in a press fit connection. This press fit connection frictionally engages an inner surface 142 (shown in FIG. 3) of the insert housing 134 with the lateral surface 120 of the cleaning tip 106. The frictional engagement enables a dental hygienist to secure the brush device 100 onto the cleaning tip 106 and operate the ultrasonic scaler 102 without the brush device 100 disengaging from the cleaning tip 106. However, after use of the brush device 100, the dental hygienist may easily remove the brush device 100 from the cleaning tip 106 for disposal of the brush device 100 and sterilization of the cleaning tip 106. In some examples, a tool may be utilized to remove the brush device 100 from the cleaning tip 106 as described further below in reference to FIGS. 7A-7D.

[0049] In the example, the insert housing 134 is sized to correspond to the size of the cleaning tip 106 to ensure a secure press fit connection. Because the cleaning tip 106 may have varying sizes and shapes (e.g., to clean specific areas of teeth), the insert housing 134 may include one or more indicia to identify the size of the insert housing 134. For example, the insert housing 134 may be color-coded based on the size of the opening of the insert housing 134. In other examples, the indicia may additionally or alternatively include a marking or symbol to correspond to the size of the opening of the insert housing. In other examples, the indicia may be formed on the base 138 and/or the cleaning element 140.

[0050] When secured on the ultrasonic scaler 102, the brush device 100 only covers a portion of the lateral surface 120 of the cleaning tip 106 so that the coolant outlet 114 is unobstructed. As such, coolant can still be channeled towards the distal end 112 to cool the cleaning tip 106 and provide fluid for cavitation. Additionally, the brush device 100 vibrates with the distal end 112 such that cavitation is still induced for teeth cleaning, while the cleaning element 140 functions to clear the teeth of the removed plaque and stain. Furthermore, the cleaning element 140 is configured to also be used with prophy paste so that the ultrasonic scaler 102 may also be used for polishing. Thus, eliminating the need of a second polishing device for teeth cleaning procedures.

[0051] FIG. 3 is a cross-sectional view of the brush device 100 coupled to the ultrasonic scaler 102. In the example, the insert housing 134 may extend into the base 138, but not entirely through the entire length L of the base 138. For example, the insert housing 134 extends more than ½ the length of the base 138 so that the brush device 100 may be secured to the distal end 112 without undesirably disengaging as described herein. In other examples, the insert housing 134 may extend between ½ and ¾ of the length of the base 138. In further examples, the insert housing 134 may extend more than ¾ of the length of the base 138.

[0052] Additionally, in the example, the opening 136 extends the entire way through the insert housing 134 so that the point 122 of the distal end 112 may extend through the insert housing 134 and be positioned adjacent to the base 138. In other examples, the insert housing 134 may have the end that is within the base 138 be enclosed such that the point 122 of the distal end 112 is fully enclosed within the insert housing 134. In alternative embodiments, the insert housing 134 may extend the entire way through the length L of the base 138 and the opening 136 extends the entire way through the insert housing 134 so that the point 122 of the distal end 112 is positioned proximate the cleaning element 140 and can more easily dissipate heat during operation of the ultrasonic scaler 102 (e.g., see brush device 800 having an opening 836 through base 838 extending to cleaning element 840 in FIG. 8). That is, when the point 122 is within the cleaning element 140, the coolant can more easily reach the point 122 to keep the cleaning tip 106 cool. In other examples, the inner surface 142 of the insert housing 134 may include one or more channels (not shown) extending therethrough. For example, one or more channels extending radially from the opening 136 and along the entire length of the insert housing 134. The channels are configured to enable coolant (e.g., water) to flow along the lateral surface 120 and towards the point 122 for cooling the cleaning tip 106 during operation.

[0053] In one example, the lateral surface 120 of the cleaning tip 106 defines a longitudinal axis 144. The brush device 100 is coupled to the distal end 112 such that the brush device 100 extends along the longitudinal axis 144 and the cleaning element 140 extends substantially parallel to the longitudinal axis. 144. As such, the shape of the distal end 112 may still be used to access teeth areas as required or desired with the brush device 100 extending therefrom.

[0054] FIG. 4A is a side view of the brush device 100. FIG. 4B is a top view of the brush device 100. Referring concurrently to FIGS. 4A and 4B, the brush device 100 includes the insert housing 134 having the opening 136 to enable the brush device 100 to be press fit onto the ultrasonic scaler as described above. The base 138 extends about the insert housing 134 and supports the cleaning element 140. In the example, the base 138 is substantially cylindrical in shape having a first end 146 and an opposite second end 148 defining the length L thereof. The base 138 may be formed out of an elastomeric rubber-type material. The base 138 defines a longitudinal axis 150 that extends along the length L.

[0055] Extending from the first end 146 is the insert housing 134 along the longitudinal axis 150. By extending the insert housing 134 from the base 138, the surface area for frictional engagement with the ultrasonic scaler increases, thereby enabling the brush device 100 to vibrate with the cleaning tip. In other examples, the first end 146 of the base 138 may not include the insert housing, and the base 138 defines the opening 136 such that the base 138 directly engages with the cleaning tip. The insert housing may be formed with plastic or composite materials.

[0056] Extending from the second end 148 is the cleaning element 140 along the longitudinal axis 150. In the example, the cleaning element 140 may be offset from the perimeter of the second end 148, as illustrated in FIG. 4B. The cleaning element 140 may include a circular tuft of bristles (e.g., tuft of bristles 141 as shown in FIGS. 5A-5D), that extends substantially straight and parallel to the longitudinal axis 150. The bristles may be sufficiently ridged so as to vibrate with the cleaning tip as described herein. Such bristles may be made polymeric and may include, for example, polyamide or polyester. The individual bristles may have a uniform diameter across the entire tuft, or sizes may vary within the tuft. In other examples, the cleaning element 140 may also include elastomeric structures (e.g., ridges, bumps, etc.), foams, and combinations thereof.

[0057] In the example, a head 152 of the cleaning element 140 may be substantially orthogonal to the longitudinal axis 150 such that the tuft is squared off and can be used to provide prophy paste for polishing. In other examples, the head 152 may be round, tapered, pointed, or any other shape as required or desired. For example, the perimeter of the head 152 may include a taper 154. Additionally, or alternatively, the bristles maybe more flexible and formed from soft plastic material such as rubber or thermoplastic elastomer (TPE). By using bristles, the brush device 100 may be used with dental implants and other dental and orthodontic appliances. In some examples, some or all of the cleaning element 140 may extend from at least a portion of a sidewall 156 of the base 138 (e.g., orthogonal to the longitudinal axis 150) so that the sides of the base 138 may be used for teeth cleaning. In examples, the cleaning element 140 that extends from the sidewall 156 may have a shorter height than the cleaning element 140 extending from the second end 148. The cleaning element 140 may be securely attached to the base 138 in any suitable manner. For example, stapling, gluing, or molding. In examples, the cleaning element 140 may have any suitable height H, as required or desired. For example, the cleaning element 140 may have a height H between 2 mm and 6 mm. In other examples, the cleaning element 140 may have a height H between 3 mm and 5 mm. In further examples, the cleaning element 140 may have a height H of approximately 4 mm. In still other examples, the cleaning element 140 may have a height H that is approximately equal to the length L of the base 138.

[0058] FIGS. 5A-5D are alternative configurations of the brush device. Certain components are described above, and as such, are not necessarily described further. FIG. 5A illustrates a brush device 100a with a generally diamond shaped base 138a. In this example, since the base 138a is in a more elongate configuration the insert housing 134 may not necessarily be required, although one may be used as required or desired. In this example, the base 138a may be directly coupled to the ultrasonic device. Additionally, a cleaning element 140a may be smaller than the example described above for more detailed cleaning. FIG. 5B illustrates a brush device 100b with a generally tapered, frustoconical shaped base 138b. In this example, the base 138b may be elongated so as to not require the insert housing 134, although one may be used as required or desired. FIG. 5C illustrates a brush device 100c with a generally square/cylinder shaped base 138c and may include an insert housing 134, such as insert housing 134c. FIG. 5D illustrates a brush device 100d with an insert housing 134d portion that has a generally flared shape. FIG. 5E illustrates a brush device 100e with a generally square/cylinder shaped base 138e and an insert portion 135. In the examples illustrated in FIGS. 5A-5E, the different shaped bases/insert housings and overall configurations enable for selective positioning of the ultrasonic scaler, and use of differing ultrasonic scalers, during teeth cleaning operations.

[0059] FIG. 6 is a perspective view of the brush device 100 and ultrasonic scaler 102 cleaning teeth 158. The brush device 100, including the insert housing, the base, and the cleaning element are sized to fit within a patient's mouth for teeth cleaning procedures. In operation, the brush device 100 is used for cleaning procedures on the teeth 158 and above the gum line. The cleaning element enables for plaque and stain to be removed. Additionally, or alternatively, the brush device 100 can be used with prophy paste or other chemical substances so that the ultrasonic scaler 102 can also polish the teeth 158. This enables for the number of tools used for teeth cleaning procedures to be reduced.

[0060] FIGS. 7A-7D illustrate exemplary installation and removal steps of the brush device 100 to and from the ultrasonic scaler 102. Referring concurrently to FIGS. 7A-7D, a tool 160 may be used to install and/or remove the brush device 100 to and from the ultrasonic scaler 102. In the example, the tool 160 includes a first end 162 and an opposite second end 164. The tool 160 may have a dog-leg shape such that the first end 162 is oriented at an angle from the second end 164. In other examples, the tool 160 may have any other shape that enables the tool to function as described herein, such as a straight bar-shape. The first end 162 may include a hole 166 defined therein that is sized and shaped to receive a portion of the brush device 100. In an example, the hole 166 may extend through the entire thickness of the tool 160. In other examples, the hole 166 may extend only partially through the thickness of the tool 160. The second end 164 may include a slot 168 defined therein that is sized and shaped to receive a portion of the brush device 100 and/or the ultrasonic scaler 102. In an example, the slot 168 may extend in a direction that is substantially orthogonal to the direction of the hole 166.

[0061] Beginning with FIG. 7A, the brush device 100 may be installed onto the ultrasonic scaler by placing the brush device 100 onto the tool 160. More specifically, the cleaning element 140 may be placed at least partially into the hole 166 at the first end 162 of the tool 160. As such, the insert housing 134 may be oriented in an upwards direction such that it may receive the ultrasonic scaler.

[0062] Turning now to FIG. 7B, the distal end 112 of the ultrasonic scaler 102 may be inserted into the insert housing 134 while the brush device 100 is supported on the tool 160. In some examples, the ultrasonic scaler 102 is twisted (e.g. ¼ of a turn) while applying pressure P to secure the brush device 100 to the ultrasonic scaler 102. The tool 160 may then be removed from the brush device 100 and the dental hygienist may carefully tug on the brush device 100 to verify that it is secure on the ultrasonic scaler 102. The coolant flow to the ultrasonic scaler 102 can be regulated so that a fine spray is channeled from the scaler and the coolant is flowing over the brush device 100.

[0063] After the cleaning procedure is finished, the brush device 100 may then be removed from the ultrasonic scaler 102 and disposed of in accordance with known standards for disposal of biohazard materials. As illustrated in FIG. 7C, the brush device 100 may be placed onto the tool 160. More specifically, the insert housing 134 is placed within the slot 168 at the second end 164 of the tool 160. As such, the tool 160 may be used for leverage against the base 138 to remove the brush device 100 from the ultrasonic scaler 102. In other examples, the distal end 112 of the ultrasonic scaler 102 may be placed within the slot 168 such that the base 138 is adjacent to the tool 160. Turning now to FIG. 7D, once the brush device 100 is partially disposed within the slot 168, the ultrasonic scaler 102 is pulled P in a downward direction and away from the tool 160. The tool 160 holds the brush device 100 in place, via the base 138, such that the brush device 100 disengages with the ultrasonic scaler 102. The dental hygienist may place a finger and/or thumb over the brush device 100 to assist in securing the brush device 100 to the tool 160.

[0064] FIG. 9 is a perspective view of an example brush device 100d and ultrasonic scaler 202. The ultrasonic scaler 202 may include a handle 204 and a cleaning tip portion 206 extending from a distal end 208 of the handle 204. The handle 204 may include a transducer (not shown) to convert electricity into mechanical energy at the cleaning tip 206. In some examples, the transducer may be magneostrictive or piezoelectric. The transducer vibrates the cleaning tip portion 206 at an ultrasonic frequency to induce a cavitation effect that may be used to facilitate the cleaning of teeth. The handle 204 may also have a coolant inlet line (not shown) to channel coolant (e.g., water) to an opening/aperture 214 (as shown in FIG. 12) of the cleaning tip portion 206.

[0065] The cleaning tip 206 may include an elongated proximal end 210 that is configured to be received within the distal end 208 of the handle 204 and be secured therein. Opposite the proximal end 210, the cleaning tip portion 206 may have a distal end 212 that may be configured to vibrate at high frequencies. It is appreciated that while one example of an ultrasonic scaler 202 and cleaning tip portion 206 is depicted in the figures, the brush device 100d as described herein may be used with any suitable type of ultrasonic scaler 202.

[0066] In one example, distal end 212 may include a first lip edge 216 and a second lip edge 218 spaced apart from first lip edge 216, and extending out circumferentially about distal end 212. In one example, the second lip edge 218 may be disposed at about a distal most end of distal end 212. The distal most end of distal end 212 may include opening/aperture 214 formed therein to allow liquid (e.g., water) to pass therethrough. First lip edge 216 and second lip edge 218 may be of generally the same or differing diameters. In one example, first lip edge 216 may have a slightly larger diameter than that of second lip edge 218.

[0067] The brush device 100d may include an insert housing 134d having an opening 136d in one end thereof to enable the brush device 100d to be installed onto the distal end 212 portion of the cleaning tip 206. A base 138d may extend from an end of the insert housing 134d opposite that of opening 136d, and may support a cleaning element 140d extending from base 138d. In one example, the cleaning element 140d may include a tuft of bristles 141, such as tuft of bristles 141d. In one example, the tuft of bristles 141d may be formed from a plastic-based material so that the ultrasonic scaler 202 may be used for cleaning implants and other dental appliances.

[0068] FIG. 10 is side view of the brush device 100d coupled to the ultrasonic scaler 202. In one example, to attach the brush device 100d to the ultrasonic scaler 202, the second lip edge 218 of the distal end 212 of the cleaning tip portion 206 may be inserted into opening 136d of insert housing 134d of the brush device 100d. The insert housing 134d preferably fits circumferentially about an outer periphery of at least the second lip edge 218. This circumferential fit connection frictionally engages an inner surface 142d of the insert housing 134d with an outer peripheral surface 220 of at least the second lip edge 218. In another example, the brush device 100d may be coupled to the ultrasonic scaler 202 by inserting the second lip edge 218 and at least a portion of the first lip edge 216 of the distal end 212 of the cleaning tip portion 206 into opening 136d of insert housing 134d of the brush device 100d. In this example, the inner surface 142d of the insert housing 134d frictionally engages with the outer peripheral surface 220 of the second lip edge 218 and at least a portion of an outer peripheral surface 222 of the first lip edge 216 of the distal end 212 of the cleaning tip 206. The frictional engagement enables the brush device 100d to be securely fit onto the distal end 212 of the cleaning tip 206, and for the ultrasonic scaler 202 to operate without the brush device 100d disengaging from the distal end 212 of the cleaning tip 206.

[0069] In one example, the insert housing 134d may be made of an elastomeric material, and is preferably sized and shaped to correspond to the size and shape of the distal end 212 of the cleaning tip 206 to ensure a secure connection, e.g., a circumferential friction fit. Because the distal end 212 may have varying sizes and shapes (e.g., to clean specific areas of teeth), the insert housing 134d may include one or more indicia to identify the size of the insert housing 134d. For example, the insert housing 134d may be color-coded based on the size of the opening of the insert housing 134d. In other examples, the indicia may additionally or alternatively include a marking or symbol to correspond to the size of the opening of the insert housing 134d. In other examples, the indicia may be formed on the base 138d and/or the cleaning element 140d.

[0070] In one example, when secured on the ultrasonic scaler 202, liquid may be channeled by the ultrasonic scaler 202 to the base 138d through opening 214 of the distal end 212. Additionally, the brush device 100d may vibrate with the distal end 212 such that cavitation may still be induced for teeth cleaning, while the cleaning element 140d functions to clear the teeth of the removed plaque and stain. Furthermore, the cleaning element 140d may be configured to also be used with other liquids or pastes, such as prophy paste, so that the ultrasonic scaler 202 may also be used for polishing for example. Thus, eliminating the need of a second polishing device for teeth cleaning procedures.

[0071] FIG. 11 is a cross-sectional view of the brush device 100d coupled to the ultrasonic scaler 202. In one example, the insert housing 134d may extend out from the base 138d. For example, the insert housing 134d may extend out a length from the base 138d, such that the brush device 100d may be secured to the distal end 212 without undesirably disengaging as described herein. In one example, the insert housing 134d may extend out a length from the base 138d, such that at least the second lip edge 216 may be inserted within insert housing 134d. In a further example, insert housing 134d may extend out a length from the base 138d, such that second lip edge 218 and at least a portion of the first lip edge 216 may be inserted within insert housing 134d. In a further example, insert housing 134d may flare out from the base 138d, such that the insert housing 134d has a larger diameter than that of the base 138d.

[0072] Additionally, in one example, when installed a distal most end of distal end 212 of the cleaning tip 206 may be positioned adjacent to a first end of the base 138d, such that opening 214 is aligned with an opening 145 (similar to opening 836 shown in FIG. 8), extending through the base 138d from its first end through to a second opposing end thereof and opening to cleaning element 140d. That is, when the distal end 212 is installed within the brush device 100d, liquid can pass from opening 214 of the distal end 212 of the cleaning tip 206 through the base 138d into the cleaning element 140d, and thereby providing liquid to, for example, the bristles 141d, of the cleaning element 140d.

[0073] FIGS. 13A and 13B show side views of an exemplary brush device 100e and ultrasonic scaler 302. The ultrasonic scaler 302 may include a handle 304 and a cleaning tip portion 306 extending from a distal end 308 of the handle 304. The handle 304 may include a transducer (not shown) to convert electricity into mechanical energy at the cleaning tip 306. In some examples, the transducer may be magneostrictive or piezoelectric. The transducer vibrates the cleaning tip portion 306 at an ultrasonic frequency to induce a cavitation effect that may be used to facilitate the cleaning of teeth. The handle 304 may also have a coolant/fluid inlet line (not shown) to channel coolant/water (e.g., water) to a fluid outlet 314 of the distal end 308 of the handle 304. In one example, the fluid outlet 314 is configured to produce a stream of fluid that comes in contact with at least a portion of the brush device 100e.

[0074] The cleaning tip 306 may include an elongated proximal end 310 that is configured to be received within the distal end 308 of the handle 304 and be secured therein. Opposite the proximal end 310, the cleaning tip portion 306 may have a distal end 312 that may be configured to vibrate at high frequencies. In one example, distal end 312 may be disposed at an angle relative to elongate proximal end 310. In one example, distal end 312 may include an opening 313, such as a threaded “female” opening, wherein the opening 313 is configured to receive insert portion 135 of brush device 100e. It is appreciated that while examples of an ultrasonic scaler 302 and cleaning tip portion 306 are depicted in the figures, the brush device 100e as described herein may be used with any suitable type of ultrasonic scaler.

[0075] Insert portion 135 of brush device 100e may be used to install and secure the brush device 100e onto the distal end 312 portion of the cleaning tip 306. Insert portion 135 may extend from a first end of the base 138e, and cleaning element 140e may extend from a second opposing end of the base 138e. In one example, the cleaning element 140e may include a tuft of bristles 141, such as tuft of bristles 141e. In one example, the tuft of bristles 141e may be formed from a plastic-based material so that the ultrasonic scaler 302 may be used for cleaning implants and other dental appliances. In other examples, the tuft of bristles 141e may be formed from any other suitable material.

[0076] In one example, to attach the brush device 100e to the ultrasonic scaler 302, the insert portion 135 may be inserted into opening 313 of the distal end 312 portion of the cleaning tip 306 and secured thereto. In one example, insert portion 135 may include threading that corresponds with threading of opening 313, and brush device 100e may be attached to the ultrasonic scaler 302 by threading the insert portion 135 of the brush device 100e into the opening 313 of the distal end 312 of ultrasonic scaler 302 thereby securing it in place thereto. Brush device 100e may be attached to the ultrasonic scaler 302 use any other suitable technique and/or mechanism. In one example, the base 138e and insert portion 135 may be made of metal, such as stainless steel or other suitable material.

[0077] In one example, when the brush device 100e is attached to the ultrasonic scaler 302, fluid (e.g., water) may be directed by the ultrasonic scaler 302, from fluid outlet 314 of the distal end 308 of the handle 304, to the base 138e and/or cleaning element 140e (as shown, for example, by line 305 in FIGS. 13A and 13B). Additionally, the brush device 100e may vibrate with the distal end 312 such that cavitation may still be induced for teeth cleaning, while the cleaning element 140e functions to clear the teeth of the removed plaque and stain. Furthermore, the cleaning element 140e may be configured to also be used with other liquids or pastes, such as prophy paste, so that the ultrasonic scaler 302 may also be used for polishing for example. Thus, eliminating the need of a second polishing device for teeth cleaning procedures.

[0078] In one example, opening 313, for receiving insert portion 135 of the brush device 100e, may be disposed in about a substantially central area of a forward facing surface of the distal end 312 of the ultrasonic scaler 302 (as shown, for example, in FIG. 13C), and the brush device 100e may be attached thereto, at about a 90 degree angle relative to the central axis (as indicated, for example, by arrow 307) of the cleaning tip portion 306 (as shown, for example, in FIG. 13A). In another example, opening 313, for receiving insert portion 135 of the brush device 100e, may be disposed in a side surface of the distal end 312 of the ultrasonic scaler 302 (as shown, for example, in FIG. 13D), and the brush device 100e may be attached thereto, substantial in-line with the central axis (as indicated, for example, by arrow 307) of the cleaning tip portion 306 (as shown, for example, in FIG. 13B).
