An apparatus for recommending whether to discard a dental file during use includes a processor, a plurality of laser profilometers oriented to direct their respective laser beams toward a first spatial region where a dental file is configured to travel along, a plurality of cameras oriented toward a second spatial region where the dental file is configured to travel along, at least one selected from the group consisting of a display screen and a speaker, and a non-transitory, tangible program storage medium, embodying a program of instructions executable by the processor to perform method steps for determining to discard the dental file. The method includes inserting the file in the apparatus to inspect the file with the cameras and the laser profilometers when the file is new and subsequently when the file has been used to determine whether the file should be discarded.

The present invention relates generally to the field of pressure washer wands and a cleaning attachment that can be attached to any standard pressure washer wand. The attachment has a roller assembly with a bristled roller head. The head can be positioned in front of the spray tip of a wand such that water that exits the wand and causes the head to spin.

An applicator for applying a pasty or flowable substance is provided. The applicator comprises an applicator element comprising a plurality of rods that are joined at a proximal end of the applicator element. The plurality of rods extend from the proximal end of the applicator element separately to a distal end of the applicator element, where they are reunited. Each of the plurality of rods has a helical shape between the proximal end of the applicator element and the distal end of the applicator element. Each of the plurality of rods has no outwardly protruding bristles or projections.

The present invention discloses a prophy angle assembly for cleaning teeth with braces comprising a housing installed with a driving mechanism including a driven gear and driving gear. A cup is co-molded with the driven gear enclosing a plurality of bristles having tips extending from a surface of the cup. A gap is formed between an inner wall of the cup and the bristles. A splatter guard is attached to the housing and positioned in constant contact with the cup to prevent splatter while cleaning of dental arcade.

A suction assembly, toothbrush, and method are provided that suction fluids and debris resulting from brushing. The suction assembly includes a housing configured to couple to the toothbrush so that a portion extends around sides and a back of the toothbrush head and is spaced from the toothbrush head by a gap. The suction assembly further includes a vacuum pump, a collection reservoir, and one or more conduits that couple the vacuum pump, suction head portion, and collection reservoir to apply a suction around the toothbrush head through the gap and deposit suctioned material in the collection reservoir.

An oral care implement, oral care system, and/or method for detecting the presence or absence of hemoglobin/blood in a user's oral cavity. The oral care implement may include a cavity for receiving a saliva sample from a user and a closure member that can close the cavity for purposes discussed herein. The oral care system may include a handle, a refill head, and a collection cup, with the refill head and collection cup being detachably coupled to the handle. A sample of the user's saliva may be introduced into the collection cup. The handle may include a sensor that can obtain information related to the presence or absence of hemoglobin/blood in the oral cavity or in a sample of the user's saliva. The sensor may be operably coupled to a processor that can determine whether hemoglobin is present in the sample based on the information obtained by the sensor.
