• the neck 90 may define a receiving formation 92 to receive the working tip 86.
• the receiving formation 92 may include one or more recesses 94 configured to receive the lateral protrusion 88 of the working tip 86. Three such recesses 94i, 94 . 94 3 are illustrated in the embodiment of FIGS. 16A-18.
• the recesses may be disposed at 90-degree offsets with respect to one another, in an embodiment, as illustrated in FIG. 17. In FIGS.
• the working tip 86 is inserted such that the lateral protrusion 88 is disposed in recess 94 2 .
• the working tip 86 is inserted such that the lateral protrusion 88 is disposed in recess 94s.
• the working tip 86 is rotated 90 degrees in FIG. 16B relative to FIGS. 16A and 18.
• FIGS. 19A and 19B are front and perspective views, respectively, of an example embodiment of an interproximal brush tool attachment 90 that may find use with a double- ended dental tool according to the present disclosure.
• the interproximal brush tool attachment 90 may include a set of bristles that taper from center to edge in all lateral directions. Accordingly, the center of the bristle set includes the longest bristles, and the edges of the bristle set includes the shortest bristles.
• This interproximal brush tool attachment 90 may be particularly well-suited for cleaning between the user’s teeth in the space where the gum and teeth meet.
• any of the attachments 60, 62, 64, 66, 68, 70, 72, 84, 90, or other appropriate attachment may find use as an attachment 14i, l4 2 with the main body portion 12.
• the attachments 60, 62, 64, 66, 68, 70, 72, 84, 90 may be interchangeable used on either end 14i, l4 2 of the main body portion 12, in embodiments.
• Each attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 may include a base portion 74, a working portion 76, and a neck 78 that extends from the base portion 74 to the working portion 76.
• the respective working portion 76 of each attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 may include one or more components for observing or treating a user’s oral cavity.
• the working portion 76 of the bristle brush tool attachment 60 comprises a plurality of soft bristles for brushing
• the working portion 76 of the orthodontic brush tool attachment 62 includes two sets of stiff bristles separated and shaped so as to clean orthodontia
• the working portion 76 of the scaler tool attachment 64 includes a stiff, pointed working tip for cleaning between teeth and at the interface of teeth and gums, and so on.
• the base portion 74 may define a longitudinal aperture 80. As shown in FIGS. 5,
• an inner surface of the base portion 74 may include a receiving formation 82 or other mating structure that is complementary with a mating structure on the main body portion 12, such as the protrusion 30.
• the base portion 74— and thus the attachment 60, 62, 64, 66, 68, 70, 72, 84, 90— may be coupled to the main body portion 12 by inserting the base portion 74 over the longitudinal end of the main body portion 12 such that at least a portion of the reduced-diameter portion 28 of the main body portion 12 (e.g., the light housing 38) extends into and at least partially through the longitudinal aperture 80 of the base portion 74.
• the base portion 74 may be secured to the main body portion by coupling of the receiving formation 82 with the protrusion 30 (e.g., a snap-fit), as well as by friction of contact between the base portion 74 and the outer cylindrical portion 18, and between the base portion 74 and the light housing 38.
• the outer cylindrical portion 18 and the light housing 38 may be spaced apart from one another so as to define an annular space, and the base portion 74 may insert into that annular space so as to be held by friction with both the outer cylindrical portion 18 and the light housing 38.
• an attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 is coupled with the main body portion 12, the longitudinal axis A may extend through the aperture 80.
• the aperture 80 may additionally serve as a safety precaution.
• the attachments 60, 62, 64, 66, 68, 70, 72, 84, 90 include robust features for ensuring a secure connection between the attachments 60, 62, 64, 66, 68, 70, 72, 84, 90 and the main body portion, in the unlikely event that an attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 becomes inadvertently dislodged from the main body portion 12 and is partially swallowed by a user, the aperture 80 will allow the passage of air so as to prevent choking by the user.
• an attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 When an attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 is coupled with the main body portion 12, the attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 may be substantially radially flush with the main body portion 12, in some embodiments. That is, an outer diameter of the base portion 74 may be substantially the same as an outer diameter of the main body portion that is immediately longitudinally adjacent to the base portion 74, such that the base portion 74 of the attachment 60, 62, 64, 66, 68, 70, 72, 84, 90 may maintain the outer profile of the main body portion 12, as illustrated in FIGS. 1 and 5.
• the distal surface of the base portion 74 may be substantially flush with the light-transmissive cover 40, in some embodiments. That is, the base portion 74 and the light- transmissive cover 40 may appear to collectively define a substantially flat surface, as illustrated in FIGS. 1 and 5.
• the base portion 74, neck portion 78, and one or more portions of the working portion 76 may comprise a monolithic body of material, in embodiments. That material may be, for example, a polypropylene material or other polymer.
• the tool 10 and attachments 60, 62, 64, 66, 68, 70, 72, 84, 90 may provide many functional advantages.
• each of the attachments 60, 62, 64, 66, 68, 70, 72, 84, 90 may effectively clean a user’s teeth, a portion thereof, or an orthodontic treatment, and/or allow the user to view the user’s oral cavity.
• the attachments 60, 62, 64, 66, 68, 70, 72, 84, 90 may be selectively couplable with the main body portion 12, thus allowing a user to customize a personal tool 10 and to use many different attachments with a single main body portion 12.
• the tools that may be available for the scaler 10 may be sufficiently durable that a user can use each tool numerous times before the tool requires replacement.
• the ends of the main body portion may be curved in opposite directions, such that the tools extends in opposite directions from the main body portion, thereby enabling the user to quickly and easily flip the scaler in his or her hand to use the opposite end of the scaler 10 (e.g., the tool on the opposite end).
