Description: HOLDER FOR TOOTH TREATMENT MATERIAL AND METHOD The invention relates to holders for tooth treatment material. The invention provides a holder for tooth treatment material, such as polishing paste, the holder having a cup, a connector and a base adapted to support the cup in an upright position on a horizontal surface. The prior art uses metal rings and plastic fingerclips to hold polishing paste in a single use container. For example Nupro (trademark) dental polishing paste is sold by Dentsply International Inc in a single use container. One prior art clip holds the container to a finger of a dentist (or hygienist) while the single use container is fixed on top of the clip. Prior art fingerclip holders are able to clasp single use containers, but are not adapted to hold paste without a container. A prior art fingerclip, while in use is held firmly to the finger which presses on the finger becoming uncomfortable after a while. Sharp edges of the metal clips damage the user's examination glove (s). Prior art holder mounting and removal require the use of a second hand to move the holder from or to the user' s finger. Thus, a prior art holder fingerclip cannot be removed from the user' s finger by the hand on which the holder is mounted, so a second hand is needed. Prior art holders bend and loosen the hold on the container when removing polishing paste from the container. Retention for paste containers in prior art holders is therefore poor and decreases over time. Holders in accordance with the invention provide the user with the ability to hold all kinds of dental materials and medicaments like polishing paste in cups, in bulk, fluoride varnish and gel and other materials for professional use. Holders in accordance with the invention make it easy to directly apply material into the patient's mouth. Holders in accordance with the invention provide users with the ability to hold a holder and a dental instrument or a dental tool at the same time in one hand without any discomfort or interference by the dental tool or instrument in the use of the holder. Holders in accordance with the invention are made of autoclavable material. Holders in accordance with the invention has no wear or breakage of the clips by time. Holders in accordance with the invention are used in one hand with no need for a second hand to remove the holder from and/or clip the holder to the finger. Holders in accordance with the invention are easy to pick-up and put down on a tray. Holders in accordance with the invention provides the user with the ability to be used between the fingers of your choice either on right or left hand in upright or downside position. Holders in accordance with the invention provide users with the ability to be put down at the tray in upright position. Holders in accordance with the invention allow different grasps of a holder to accommodate hand positions. Tooth polishing paste is typically effectively a nonvolatile material containing abrasive particles, and is applied to teeth in a patient's mouth while supported by a motor driven rotating carrier. The prior art does not provide a tooth polishing paste holder having a cup member, a connector member and a base member wherein the cup has an inner wall with a circumference less than 10 cm, the connector connects the cup to the base and the base is adapted to support the cup in an upright position on a horizontal surface. It is an object of the invention to provide a tooth polishing paste holder having a cup member, a connector member and a base member wherein the cup has an inner wall with a circumference less than 10 cm, the connector connects the cup to the base and the base is adapted to support the cup in an upright position on a horizontal surface. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is an illustration of a prior art paste holder. Figure 2 is a perspective view of a holder in accordance with the invention. Figure 3 is a top view of the holder shown in Figures 2-6. Figure 4 is a bottom view of the holder shown in Figures 2-6. Figure 5 and 6 are enlarged side elevational views taken at right angles to each other of the holder shown in Figures 2-6. BRIEF DESCRIPTION OF THE INVENTION Tooth polishing paste holder a cup member, a connector member and a base member. The cup has an inner wall. The inner wall has a circumference less than 10 cm. The connector connects the cup to the base. Preferably, the connector integrally connects the cup to the base. The base is adapted to support the cup in an upright position on a horizontal surface. DETAILED DESCRIPTION OF THE INVENTION The invention is now described with more particular reference to FIGURES 2 through 6. Tooth polishing paste holder 10 a cup member 12, a connector member 14 and a base member 16. The cup 12 has an inner wall 18. The inner wall 18 has a circumference less than 10 cm. Preferably, the inner wall 18 has a circumference less than 6 cm. The connector 14 connects the cup 12 to the base 16. The base 16 is adapted to support the cup 12 in an upright position on a horizontal surface. The connector 14 is substantially rectangular in cross- section. The holder 10 is made of a material adapted to not melt and maintain the shape of the holder at temperatures greater than 100°C. The connector 14 has a length to width ratio between 1 to 1 and 4 to 1, and a width to depth ratio between 2 to 1 and 30 to 1. Preferably, the connector 14 has a length to width ratio between 1 to 1 and 3 to 1, and a width to depth ratio between 2 to 1 and 10 to 1. Holder 10 is preferably used in combination with a container 20 which supports tooth polishing paste therein while the container is supported by the cup 12. Holder 10 is preferably used in combination with tooth polishing paste while the paste is supported by the cup 12. Preferably the inner wall 18 has a circumference less than 5 cm. Preferably the paste comprises fine particles of abrasive material . Preferably cup 12 has a truncated rounded upper face and truncated rounded lower face, and said base has a truncated rounded upper face and a planar lower face. Holder 10 has a central axis A which extends vertically while the lower face 22 of the base 16 is positioned in a horizontal plane, for example by being substantially coplanar with and supported by a horizontal surface. The connector 14 extends laterally from the vertical axis in two orthogonal directions B and C. Preferably the connector extends laterally more than twice as far in one orthogonal direction C than in the other orthogonal direction B. More preferably the connector extends laterally more than thrice as far in one orthogonal direction C than in the other orthogonal direction B. Most preferably the connector extends laterally more than four times further in one orthogonal direction C than in the other orthogonal direction B. The invention provides a method of dispensing tooth polishing paste by providing paste holder having a cup, a connector and a base, the connector connecting the cup to the base, the base being adapted to support the cup in an upright position on a horizontal surface, the cup supporting tooth polishing paste, and dispensing the tooth polishing paste from the cup. The user positions a container in the cup. The container supports dental treatment material such as tooth polishing paste. Alternatively the user positions dental treatment material such as tooth polishing paste in the cup. Conveniently the user positions the connector between two fingers of one of the user's hands. Then the user applies the paste either to a hand held dental tool or hand held dental device or to a tooth polishing device for polishing one or more teeth in a patient's mouth. Preferably the paste comprises fine particles of abrasive material. Preferably the tooth polishing paste holder 10 has an overall length (L) which is less than 5 cm and more than 0.5 cm, and cup 12 has a width (W) which is less than 5 cm and more than 0.5 cm.
