Abstract: This invention takes advantages of color characteristics of medical devices for the cosmetic and indication purposes. For example, the appearances of the metallic brackets used in orthodontics are improved with colors other than the original metallic color by surface treatment using plasma techniques. For example, orthodontic brackets are made with piezochromic materials. When the archwire's torsion and bending forces are fading due to the movement of the teeth, the color of the pressure sensitive brackets will be changed, and the need of archwire's readjustment to have proper torsion and bending forces is signalized. For example, rehabilitation equipments are made with piezochromic materials. When the pressures exerting on the rehabilitation equipments are different, different colors of the equipments are displayed, and the therapists can then act accordingly.

Abstract translation: 本发明利用了用于化妆品和指示目的的医疗装置的颜色特性。 例如，通过使用等离子体技术的表面处理，在正畸中使用的金属支架的外观通过不同于原始金属颜色的颜色而改善。 例如，正畸托架由压电色素材料制成。 当弓丝的扭转和弯曲力由于齿的移动而衰减时，压敏支架的颜色将改变，并且需要将弓丝的重新调整具有适当的扭转力和弯曲力。 例如，康复设备是用压电变色材料制成的。 当康复设备施加的压力不同时，会显示不同颜色的设备，然后治疗师就可以相应地行动。

Abstract: A harvested botanic offshoot has a first end with a portion thereof stripped of bark forming a botanic cleaning component that is adapted for insertion into a human mouth for dental cleaning. A proximal end of the offshoot can be carved down in size and releasably installed in a socket or internal channel inside a dental cleaning assembly. A motor inside the dental cleaning assembly can vibrate, oscillate or rotate the botanic cleaning component inside a user's mouth. The dental cleaning assembly has an opening arranged to allow at least a portion of the botanic cleaning component to extend outside the body portion of the dental cleaning assembly.

Abstract: Provided is a dental handpiece which can prevent degradation in visibility of a surgical field. The anti-reflection layer 100 is formed on the top surface and the side surface of the head portion 241 of the lid member 24 close to the root canal of the tooth, to which the operator pays attention, and further on the outer surface of the second cylindrical member 12 (refer to FIG. 3). Therefore, the reflection of light of a dental lighting tool provided with the anti-reflection layer 100 is suppressed, and degradation in visibility of a surgical field can be avoided. In addition, visibility of stains such as proteins adhering to the lid member 24 and the second cylindrical member 12 is improved, and cleaning thereof is facilitated.

Abstract: The present invention relates to a dental drill (10) formed of titanium or a titanium alloy having a hardness greater than pure titanium, said drill extending along a central axis (A) from a proximal end (14) to a distal end (16). The drill comprises a shank (12) arranged in a proximal end region of the drill (10) and extending along the central axis (A), a flute portion (20) arranged distally to and running coaxially with the shank (12), said flute portion (20) comprising two or more flutes (22a, 22b, 22c) extending along the flute portion (20) and being interposed by lands (24a, 24b, 24c), the flute portion further comprising a central solid web and a drill tip (26) directly adjoining the distal end (28) of the flute portion (20) and comprising two or more flanks (25a, 25b, 25c) which taper radially inwardly from the distal end of each land in the distal direction toward the central axis (A), each flank (25a, 25b, 25c) comprising a cutting edge (30a, 30b, 30c). According to the invention, at the distal end of the drill point (26) at least one groove (32, 33a, 33c) is formed in the web such that the distal most end (36a, 36b, 37b, 37c) of at least one of the flanks (25a, 25b, 25c) is located radially remote from the central axis (A).
