This technology pertains generally to human or animal oral hygiene devices, systems and methods and more particularly to an apparatus and methods for safely and effectively dislodging and removing microorganisms and debris from the dorsum of the tongue and other surfaces.
The upper surface (dorsum) of the tongue has many papillae, furrows and groves that can collect debris and plaque as well as harbor undesirable microorganisms that can generate halitosis and foul tastes in the mouth. In addition, the tongue can accumulate materials from sinus drainage that can also contribute to poor oral hygiene.
Visits to the dentist for the typical continuing care appointments entail scaling (scraping) of plaque and calculus from the tooth surface followed by polishing of any residual stain away from the tooth. This process does not completely eliminate bacteria from tooth surfaces, but it may reduce and disturb the microbiota load. Although it is well known that the tongue presents crevices between the papillae on the surface where dental procedure debris accumulates and can allow microbes to proliferate, this dental debris is usually ignored by the clinical team. Furthermore, tongue cleaning is often not common in the daily home hygiene regimen for most patients, leaving the dental debris intact. This represents a void in oral hygiene care that needs to be addressed.
Because the tongue is one of the largest reservoirs of microbiota in the oral cavity, various tongue cleaners have been developed to attempt to loosen and remove debris from the folds and grooves as well as other materials that may coat the tongue. Tongue cleaning devices in the art include a variety of washes, tongue scrapers, tongue brushes and other structures disposed on a toothbrush handle at the end opposite the tooth-brush bristles. However, brushes and scrapers may not adequately reach the bottom of the grooves and furrows allowing material to remain. Furthermore, the material dislodged by these devices may not be completely removed from the mouth and may be swallowed by the patient or allow repopulation of undesirable microorganisms. Such devices have also been known to stimulate the gag reflex resulting in an incomplete cleaning of the tongue because the procedure is not well tolerated by the patient or user.
Therefore, there is a need for a tool for debriding tongue debris and micro biota that is inexpensive, effective and easy for dentists and dental clinical staff to use.
Devices, systems and methods are provided for effective, efficient and safe removal of accumulated debris and microorganisms from the irregular surfaces, folds and grooves of the dorsum of the tongue as well as other surfaces of the mouth. The preferred system has a debriding head that is connected to a vacuum source so that dislodged debris and fluids are removed from the mouth for disposal. The debriding head of the apparatus preferably has an oval shaped, egg-shaped or triangular shaped head with rounded corners that can be easily inserted and withdrawn from the mouth of the patient. The head is also hollow with an interior that is open to a tubular connection section that is configured to connect to a vacuum source and collection vessel. The shaped head also has at least one flattened lower surface with one or more intake openings that allow debris, fluids and airflow to pass from the openings through the head and tubular connection section to the collection vessel for disposal.
The flattened surface of the head also has one or more rows of bristles, blunt barbs or flexible spines with rounded tips that are associated in proximity to the openings of the head. The rows of bristles are preferably in parallel formation with the elongate openings in the head. In other embodiments, the openings are circular or oval and oriented linearly with rows of bristles. In other embodiments the bristles and openings are oriented randomly on the flattened surface of the head. The bristles may be made of materials that are flexible or semi-rigid.
The debris removal portion of the system has a vacuum source that is coupled to a collection vessel and debriding head with collection tubes. The collection vessel is preferably a sealed container with and input duct and a vacuum duct that extends into the interior of the collection vessel. In one preferred embodiment, the input duct and the vacuum duct have pressure sensitive ball valves that are configured to close with abrupt changes in internal pressure within the vessel. These valves effectively stop the backflow of collected materials from the vessel to the head or out of the vessel to the vacuum source in this embodiment.
The apparatus head and collection structures for debriding of tongue debris and micro biota may be disposable or may be capable of disinfection and reuse. The debriding head is preferably made from a semi-rigid or rigid material that will not significantly deform in the presence of the internal vacuum pressure or bend excessively when the head is applied to the tongue during use.
In one embodiment the debriding tool is configured to attach to dental high-volume evacuators (HVE) which are used by dentists during dental procedures to remove debris and various fluids from the oral cavity. In this embodiment the tool attaches to the active end of the HVE tube thereby converting it to an effective tongue cleaner.
In one embodiment the tool includes stiff rounded bristles that allow for gentle scrubbing of the dorsal surface of the tongue and thereby dislodge dental debris and biota that have established in the crevices between the papillae. The HVE simultaneously suctions away the loose particles and fluids.
According to one aspect of the technology, a debriding head and system are provided that will effectively and safely, mechanically debride the dorsum of the tongue and remove debris and microorganisms from the oral cavity.
A further aspect of the technology is to provide a tongue debriding head that is adaptable to existing vacuum systems and simple to use.
Another aspect of the technology is to provide an apparatus that is inexpensive to manufacture, durable and disposable or reusable.
Further aspects of the technology described herein will be brought out in the following portions of the specification, wherein the detailed description is for the purpose of fully disclosing preferred embodiments of the technology without placing limitations thereon.
The technology described herein will be more fully understood by reference to the following drawings which are for illustrative purposes only:

An alternative embodiment of a collection vessel 60 is shown in
Each connector 62, 64 turns downward 90° and extends down into the interior 66 of the vessel 60 in the embodiment of
Referring now to
The system 80 has a vacuum source 82, such as a commercial compact suction motor, which provides the negative pressure (suction) necessary for the unit to work. The vacuum source 82 is connected to an air-tight collection jar 86 with a hose 84 that is preferably made of flexible rubber or silicon. In an alternative embodiment, the hose 84 is rigid and made from plastic or metal.
The collection jar 86 has a fluid flow prevention valve to prevent fluid flow and debris from flowing through the collection jar outlet through tube 84 into the suction pump and motor 82.
The inlet of the collection jar 86 is connected to the tongue debriding device 90 with an inlet hose 88. A backflow prevention valve is attached to the inlet of the collection jar 86 to prevent any backflow of material from the jar 86 to hose 88 and out through the device 90 with the release of negative pressure in the jar.
The system can also be consolidated and compacted into a portable or tabletop apparatus with the components in a housing. As illustrated in
In use, the vacuum suction pump 82 of system 80 is activated with the switch 96 evacuating air from hose 84 and the interior of collection jar 86 creating a negative pressure in the collection jar 86. Concurrently, suction is created in the inlet hose 88 and debriding device 90 and the system is ready for use. The head of the activated debriding apparatus 90 is inserted into the mouth and the bristles and suction are applied to the tongue. In one embodiment, the insertion and use of the apparatus 90 is preceded with an application of water or antibacterial fluid to the tongue surfaces. The bristles of the debriding head of instrument 90 are then drawn across the tongue dislodging debris, microorganisms, fluids and coatings that are removed to the collection jar 86 through the openings of the debriding head and intake hose 88.
In another embodiment, water or other fluid may be applied simultaneously with the movements of the head from a separate source or from an optional sprayer coupled to the head of the apparatus 90. The presence of additional liquids during use supports the flow of debris, microorganisms and fluids from the treatment area to the collection jar 86 where it stored for disposal.
In another embodiment, the tongue debriding instrument 90 can be reversibly or permanently fixed to a vacuum tube with a coupler 92 as shown in detail in
The technology described herein may be better understood with reference to the accompanying examples, which are intended for purposes of illustration only and should not be construed as in any sense limiting the scope of the technology described herein as defined in the claims appended hereto.
In order to demonstrate the functionality of the devices and procedures, a tongue debriding apparatus was fabricated and tested. Referring now to
As shown in the side view of
The central axis of tubular body 102 was angled with respect to the horizontal portion 106 of the debriding head 104 with the central axis at approximately 20° from the horizontal in this illustration.
Rows of parallel bristles 106 extended beyond the surface of the flat section of the debriding head 104 as seen in

In the embodiment shown in
In the embodiment shown in
As seen in
The other end of the tubular section 102 from the head 104 was a connection end 110 that was configured for attachment to a dental high-volume evacuator (HVE). As illustrated also in
The tubular section 102 may include a smooth upper internal surface that is interrupted by an about 1 mm to about 1.5 mm convexity positioned about 13 mm from orifices in the debriding head 104. This internal area engages the vent of the HVE as the device occludes the vent hole of the HVE. By engaging the vent hole of the HVE, displacement and possible aspiration of the device during function is prevented.
As also illustrated in
Accordingly, in its various embodiments the apparatus is an inexpensive, easy-to-use, non-bulky, disposable dental tool for professional debriding of tongue debris and micro biota by dentists and dental clinical staff. The tool can be attached to dental high-volume evacuators (HVE) which are used during dental procedures to remove debris and various fluids from the oral cavity. In a preferred use the apparatus to the active end of the HVE thereby converting the HVE into an effective tongue cleaner.
The stiff rounded bristles 106 allowed gentle scrubbing of the dorsal surface of the tongue dislodging debris and biota that have established in the crevices between the papillae. The HVE simultaneously suctioned away the loose particles. Conversion of the HVE to use for tongue debriding was also fast and inexpensive for the professional dental or veterinary office/clinic.
