## Background
FIELD OF THE DISCLOSURE
The disclosures made herein relate generally to implements for facilitating brushing of teeth and, more particularly, to implements for visually and/or audibly indicating a recommended duration of time that individual teeth or collections of teeth should be brushed during a toothbrushing session.
BACKGROUND
Proper brushing of teeth is an essential component of healthy oral hygiene. A major cause of the development of cavities is the presence of dental plaque. Plaque is systematically formed on tooth surfaces between brushings. If tooth brushings are inadequate, dental plaque can accumulate on tooth surfaces as well as within interdental spaces. Such accumulations of plaque from inadequate brushing can lead to bacterial growth that may form acids that destroy the protective enamel of the teeth thereby forming cavities. Improper oral hygiene is also a contributing factor in the development of many periodontal diseases. Accordingly, the proper brush stroke technique, duration and location of tooth brushing efforts are important in the maintenance of good oral hygiene.
Although the benefits of brushing one's teeth are widely recognized, children and adults alike do not always appreciate such benefits. Thus, it is frequently difficult to get such people to brush as frequently as desirable and to brush for a therapeutic length of time. Some people neglect proper brushing because they dislike the practice while others simply forget to do it. As a result, these people often only brush their teeth reluctantly as a result of coercion by a person such as, for example, a parent, a spouse, a dentist, etc.
Many people have not received adequate instruction concerning the proper techniques and duration of toothbrushing so as to properly eliminate plaque from tooth surfaces during each brushing session. Common brushing problems include the placement of the brush head on the tooth and gum surfaces and performing the brushing for a proper duration of time. In particular, many people spend an insufficient amount of time brushing lingual or palatal surfaces of the teeth and focus mainly on the facial surfaces. In addition, incisor and canine teeth often receive more attention than the molars and bicuspids (i.e., pre-molars). In order for the effects of brushing to meet the standards of proper oral hygiene, each surface of one's teeth, including the facial and palatal (for the upper teeth), facial and lingual (for the lower teeth), and the occlusal surface, must receive ample brushing time. Additionally, each of the different types of teeth, including the incisors, canines, bicuspids and molars also must receive ample brushing time.
Prior attempts to provide a teaching mechanism for providing proper instruction on toothbrushing technique, however, have concentrated primarily on the overall duration of the brushing process. They have not attempted to solve the problem of proper coverage of all teeth and surfaces of teeth in the mouth, including properly balancing the overall brushing time between each type and surface of tooth in the mouth. Known apparatuses and devices for indicating duration of brushing time and/or location of where to brush do not provide an effective means for inducing a person to brush specific one of their teeth or groups of their teeth for a recommended prescribed period of time.
Therefore, an apparatus and corresponding method of use that overcomes drawbacks associated with conventional approaches for providing instruction on toothbrushing technique and that provides an effective means for inducing a person to brush specific teeth or groups of their teeth for a recommended prescribed duration of time would be advantageous, desirable and useful.

DETAILED DESCRIPTION OF THE DRAWING FIGURES
Referring to FIG. 1, an apparatus 100 in accordance with the present invention is shown. The apparatus 100, which is referred to herein as a tooth brushing timer 100, is configured for visually and/or audibly indicating a duration of time for brushing designated teeth and specific portions thereof. Advantageously, as will be gathered from the ensuing discussion, a tooth brushing timer configured in accordance with the present invention overcomes drawbacks associated with conventional approaches for providing instruction on toothbrushing technique and provides an effective means for inducing a person to brush specific teeth or groups of their teeth for a recommended prescribed duration of time.
The toothbrushing timer 100 includes a tooth display unit 102. The tooth display unit 102 includes an upper tooth carrying structure 104 and a lower tooth carrying body 106. The upper and lower tooth carrying structures 104, 106 are in spaced apart relation with respect to each other in a manner whereby the upper and lower tooth carrying structures 104, 106 resembles a mouth in a partially or fully open orientation with a first set of the tooth-shaped bodies attached to an upper dental gum and a second set of the tooth-shaped bodies attached to a lower dental gum. The upper and lower tooth carrying structures 104, 106 jointly define a tooth carrying body. The upper and lower tooth carrying bodies 104, 106 each have a plurality of tooth-shaped bodies 108 mounted thereon. A first set of the tooth-shaped bodies 108 is attached to the upper tooth carrying structure 104 and a second set of the tooth-shaped bodies 108 is attached to the lower tooth carrying structure 106.
In one embodiment, each set of tooth-shaped bodies includes a plurality of different types of teeth. In one specific embodiment, each set of the tooth-shaped bodies 108 includes a group of adjacent incisor teeth 110, a group of adjacent molar teeth 112 (i.e., including premolars) and at least one canine tooth 114 between the incisor and molar groups of teeth 110, 112. The molar teeth 112 have an outward facing surface 116, an inward facing surface 118 and a top surface 120 (i.e., a biting/crushing face) extending therebetween. The incisor teeth 110 and canine teeth 114 have an outward facing surface 122 and an inward facing surface 124 that converge at a top edge 126 (i.e., a slicing/piecing edge).
Referring now to FIG. 2, each one of the molar teeth 112 includes three discretely illuminatable portions. Each one of the molar teeth 112 includes a molar shell 127 having a cavity therein. Within the molar shell cavity, each one of the molar teeth 112 includes a first discretely illuminatable portion 128 proximate a wall of the molar shell 127 defining its outward facing surface 116, a second discretely illuminatable portion 130 proximate a wall of the molar shell 127 defining its inward facing surface 118, and a third discretely illuminatable portion 132 proximate a wall of the molar shell 127 defining its top surface 120. A first light barrier 134 is disposed between the first and second discretely illuminatable portions 128, 130 and a second light barrier 136 is disposed between the second and third discretely illuminatable portions 130, 132. The molar shell 127 and the illuminatable portions 128, 130, 132 are light transmissive (e.g., transparent, translucent or the like). Each one of the light barriers 134, 136 is configured to limit light emitted by a respective one of the discretely illuminatable portions from substantially illuminating a respective adjacent one of the discretely illuminatable portions such that an illuminated one of the discretely illuminatable portions thereof and a non-illuminated one of the discretely illuminatable portions thereof are visually distinguishable by such illumination.
Referring to FIG. 3, each one of the incisor teeth 110 (and canine teeth, which are of substantially the same functional construction as the incisor teeth 110) includes two discretely illuminatable portions. Each one of the incisor teeth 110 includes an incisor shell 138 having a cavity therein. Within the incisor shell cavity, each one of the incisor teeth 110 includes a first discretely illuminatable portion 140 proximate a wall of the incisor shell 138 defining its outward facing surface 116 and a second discretely illuminatable portion 142 proximate a wall of the incisor shell 138 defining its inward facing surface 118. A light barrier 144 is disposed between the first and second discretely illuminatable portions 140, 142 The incisor shell 138 and the illuminatable portions 140, 142 are light transmissive (e.g., transparent, translucent or the like). The light barrier 144 is configured to limit light emitted by a respective one of the discretely illuminatable portions from substantially illuminating a respective adjacent one of the discretely illuminatable portions such that an illuminated one of the discretely illuminatable portions thereof and a non-illuminated one of the discretely illuminatable portions thereof are visually distinguishable by such illumination.
Examples of the light barriers are pigmented plastic bodies, light reflective film and the like. In one specific embodiment, the light barriers are pigmented plastic bodies disposed between adjacent ones of the illuminatable portions. In another specific embodiment, the light barriers are plastic film disposed between adjacent ones of the illuminatable portions.
As shown in FIGS. 2 and 3, each one of the illuminatable portions has a selectively activatable light output device 146 physically and/or optically coupled thereto. Each selectively activatable light output device 146 is coupled in such a manner that causes an associated illuminatable portion to become illuminated when the associated selectively activatable light output device 146 is activated. In one embodiment, all or some of the selectively activatable light output devices 146 are light emitting diodes (LED) directly coupled to the associated illuminatable portion (e.g., disposed within a cavity of the associated illuminatable portion). In another embodiment, all or some of the selectively activatable light output devices 146 include light transmitting fibers directly coupled to the associated illuminatable portion at a first end portion thereof (e.g., disposed within a cavity of the associated illuminatable portion) and coupled to a light emitting device (e.g., LED) at a second end portion thereof. In such an embodiment, all of a portion of the LED's can be located at a remote location with respect to the associated light emitting device.
In operation, an activation signal (e.g., voltage associated with an open circuit becoming a closed circuit) is issued in response to selecting (e.g., depressing) an activation selector 150. In response to control circuitry of the toothbrushing timer 100 receiving the activation signal, a first one of the illuminatable portions of one or more of the tooth-shaped bodies 108 is illuminated for a first prescribed duration of time and a second one of the illuminatable portions of such tooth-shaped bodies 108 is illuminated for a second prescribed duration of time after the first prescribed duration of time elapses and in accordance with a prescribed sequence of illuminating the discretely illuminatable portions of the tooth shaped bodies. For example, the outward-positioned illuminatable portions of all of the molar teeth 112 on one side of the upper tooth carrying structure 104 are illuminated for the first prescribed duration of time and a second one of the illuminatable portions of such molar teeth 112 are illuminated for a second prescribed duration of time after the first prescribed duration of time elapses and in accordance with a prescribed sequence of illuminating such discretely illuminatable portions thereof. In at least one embodiment, illuminating the illuminatable portions includes outputting light of varying color such that, during illumination of such illuminatable portions during each prescribed duration of time, the light changes from a first color to a second color.
The tooth display unit 102 can also include a tongue-shaped body 176, which can also be selectively illuminatable. Cleaning of the tongue plays a significant role in good oral hygiene. As such, integrated instruction of bushing of the tongue in a manner consistent with the disclosures made herein is advantageous.
In a preferred embodiment of prescribed sequence of illuminating, the objective is to provide smooth transition from one group of teeth being brushed to the next. In this manner, teeth are illuminated in a sequence such that, for a person using illumination of the tooth-shaped bodies as a guide to bushing sequence and duration, such brushing of teeth is carried out in an orderly, predictable and preferred sequence whereby the probability of neglecting to brush teeth during brushing is reduced and brushing overlaps from one group of teeth to the next. For example, illumination can start with the outward-facing surface of molars on one side of the upper tooth carrying structure, transition to the canine and incisor teeth and then to the molars on the other side of the upper tooth carrying structure. This same sequence applies for the outward facing teeth of the lower tooth carrying structure. The same sequence is carried out for the inward facing teeth of the upper and lower tooth carrying structures. Additionally, top surfaces of the molar teeth are illuminated in similar sequence.
In one embodiment, the toothbrushing timer 100 includes a timer display apparatus 160 (e.g., LED) and an audio output device 170 (e.g., speaker). The toothbrushing timer 100 is configured to visually show on the timer display apparatus 160 an elapsed period of time corresponding to a respective prescribed duration of time and to output via the audio output device 170 audio content corresponding to the respective prescribed duration of time. In this manner, the toothbrushing timer 100 is configured to display a remaining portion of a duration of time for brushing and to output audio content (e.g., music) during such duration of time. The audio content is preferably specific and/or dependent upon the duration of time such that each duration of time has respective audio content (i.e., different audio content, or reply of common audio content). It is disclosed herein that the audio content can also include audio (i.e., spoken) instructions for flossing and the like.
It is well known that boredom and tedium are two of the primary reasons that people do not spend sufficient time brushing their teeth. Accordingly, a distraction that alleviates such boredom and/or tedium is generally useful and desirable. Outputting audio content via the audio output device 170 and attached audio circuitry (e.g., MP3 player circuitry, CD player circuitry, and the like) is one such means for alleviates such boredom and/or tedium. Audio content such as music can be outputted in a manner that distracts a user of the toothbrushing timer 100, thereby making it less demanding for the user to brush their teeth for longer periods of time. In one embodiment, a single instance of audio content (e.g., a single song) can be played over the duration of operation of the tooth display unit 102 (e.g., including its output being repeated a number of times). In another embodiment, a plurality of different audio content (e.g., songs) can be played over the duration of operation of the tooth display unit 102. For example, such plurality of songs can be synchronized with operation of the tooth display unit 102 such that different audio content (e.g., a full song or portion of a song) is outputted only during illumination of a particular one or group of the discretely illuminatable portions of the tooth-shaped bodies. In this manner, the audio output and illumination the user is presented with different audio content each time the user is audibly and/or visually instructed to begin brushing a different one or set of teeth. It is disclosed herein that the audio content can be downloaded to the tooth display unit 102, accessed from a memory device attached to the tooth display unit 102, and/or retrieved from resident memory of the that tooth display unit 102.
Referring now to FIG. 4, a diagrammatic view of the toothbrushing timer 100 is shown. The toothbrushing timer 100 includes a control circuitry 180 that control and/or causes the illumination, audio and/or timing functionalities described above. To this end, the control circuitry 180 is coupled to the audio output apparatus 170, to the timer display apparatus 160 and to a lighting apparatus 182. The lighting apparatus 182 provides for selective illumination of the tooth shaped bodies 108 via actuation of the selectively activatable light output devices 146. In one embodiment, the lighting apparatus 182 includes a plurality of light emitting diodes.
The control circuitry 180 can be configured and constructed in any number of manners. The control circuitry 180 is limited only by the functionality that it provides as opposed to its design, construction or configuration. Preferably, but not necessarily, the control circuitry will be constructed using integrated circuit components (e.g., surface mounted components) mounted on a printed circuit board, flexible circuit or the like.
Accordingly, the present invention is directed to a tooth brushing toothbrush timer which is capable of presenting an amusing visual and/or informational representation of the time required for a person to brush his or her teeth. The toothbrush timer captures the attention of the user by providing an entertaining face having color-changing teeth in which the teeth change between two distinct colors. When the toothbrush timer is activated, the tooth-shaped bodies gradually transform from, for example, a non-white color to white over a predetermined period of time. Such a novel device continuously provides the user with visual feedback relating to the time period for brushing his or her teeth. In particular, the ratio of the two colors covering the teeth and/or the rate of color change is proportionate to the ratio of the time expired and time remaining for the tooth brushing operation. Thus, by knowing the time remaining for the tooth brushing operation (e.g., via audio and/or visual means), a person brushing can pace himself or herself for brushing each portion of their mouth and anxiously anticipate the moment when the tooth brushing operation will end.
In the preceding detailed description, reference has been made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments in which the present invention may be practiced. These embodiments, and certain variants thereof, have been described in sufficient detail to enable those skilled in the art to practice embodiments of the present invention. It is to be understood that other suitable embodiments may be utilized and that logical, mechanical, chemical and electrical changes may be made without departing from the spirit or scope of such inventive disclosures. To avoid unnecessary detail, the description omits certain information known to those skilled in the art. The preceding detailed description is, therefore, not intended to be limited to the specific forms set forth herein, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents, as can be reasonably included within the spirit and scope of the appended claims.
