Definitions

  • This invention relates to a method and a composition for cleaning dentures.
  • Denture cleanliness is often poor, because of improper mechanical cleansing and because of the relative inefficiency of most commercial products for chemical cleansing of dentures.
  • the immersion-type chemical denture cleansers heretofore in use include alkaline peroxides (percarbonate perborate), alkaline hypochlorites, certain dilute acids, disinfectants, and enzymes.
  • Alkaline peroxide cleansers are the most commonly used denture cleansers. They include powders or tablets which become alkaline solutions of hydrogen peroxide when dissolved in water. This type of cleanser usually combines alkaline detergents, to reduce surface tension, and agents such as sodium perborate or percarbonate which release oxygen from the solution. The oxygen bubbles are supposed to exert a mechanical cleansing effect. Clinical studies on the effectiveness of peroxide cleansers have given varied results. They seem to be most effective on new plaque and stains when the denture is soaked in the chemical solution for several hours or overnight. These products are not effective when a 15-to 30-minute soaking period is used, even though some manufacturers recommend this short period. Also, there is evidence that peroxide cleansers when used for routine denture cleansing may cause bleaching of acrylic resin. Soft or resilient denture liners are very susceptible to the harmful effects of peroxide cleansers.
  • hypochlorite cleansers though effective with over night immersion, should be used only intermittently because of bleaching, e.g., once a week. Even then, hypochlorite may damage a cobalt-chromium or stainless steel base.
  • Commercial cleansers based on hydrochloric acid are hazardous. Dilute acetic acid and similar acids may be used to dissolve calculus by overnight immersion, but should be used only at weekly or biweekly intervals because they are corrosive.
  • This invention provides a denture cleanser that is effective in maintaining plaque-free dentures, when used as a diluted soaking solution daily for periods of only about four to thirty minutes, followed by very light brushing off and rinsing. Even the toughest calcium deposits, plaque, tartar, and stains may be cleaned from dentures within about twenty minutes with rubbing with gauze containing undiluted cleanser. Four minutes suffices for normal cleaning maintenance.
  • This new cleanser basically relies on dilute citric acid.
  • it preferably employs a wetting agent and a bacterial agent or bacteristat, preferably one which is also a mycostat or mycocide, such as methyl paraben and similar materials.
  • a wetting agent preferably one which is also a mycostat or mycocide, such as methyl paraben and similar materials.
  • a bacterial agent or bacteristat preferably one which is also a mycostat or mycocide, such as methyl paraben and similar materials.
  • Isopropyl alcohol not only prevents precipitation of the citric acid during storage and at low temperatures, it also improves the cleaning action.
  • the invention is preferably prepared as a concentrate to be diluted upon use.
  • the concentrate employs citric acid at about 30% in aqueous solution, with or without isopropyl alcohol to enhance the solubility. Dilution is normally at about 4 to 1, with water, and the soaking period need last only about four to thirty minutes, depending on how bad the stains are. When used daily at the beginning of use of a new denture, four or five minutes soaking in freshly diluted solution are adequate.
  • Typical ranges of the concentrate are as follows: Water 40 to 70%
  • the formulation is, in some instances, used full strength, and in other instances is diluted up to about a 4:1 dilution (four parts water to one of concentrate).
  • a preferred bactericide +mycocide is methyl paraben (p-hydroxybenzoic acid, methyl ester) which is preferably used at a concentration of about 0.20% in the above concentrate, yielding 0.05% in the diluted cleaner. It can be used in a range of 0.25% to 0.10% in the concentrate as shown below.
  • Some typical bacterio-myco stats and cides and their concentrations are as follows, though others may be used:
  • Citric Acid 29.13 Dioctyl sodium sulfosuccinate 2.91
  • composition can be used full strength, or can be diluted with water from about 1 to 1 to about 4 parts of water to 1 part of the concentrate.
  • the cleaner needs no isopropyl alcohol and the concentration of citric acid will be about 7%, to about 8%.
  • the concentration of the wetting agent may be about 0.5%. to about 2.5%.
  • Normal maintenance requires only a daily soaking at the 1 to 4 dilution of the concentrate, preferably follow ed by light brushing and rinsing off in water.
  • they may be soaked in either, the full strength composition or in a 1:1 dilution thereof for six to eight hours a day for about a week, each time followed by scrubbing with gauze containing the undiluted composition and then rinsing.
  • the daily use of four minute soaking in the dilute 1:4 solution in water, followed by a light brushing off any residue, and rinsing is sufficient for maintenance.

Abstract

On peut proceder au nettoyage de dentiers en plongeant ceux-ci pendant quatre a trente minutes dans une solution aqueuse a 7-8% en poids d'acide citrique. La solution peut aussi contenir un agent de mouillage approprie, un bactericide-mycocide, et un alcool isopropylique.
