<p>The use is described of an aqueous formulation in the form of a gel, as a lubricant and disinfectant for canal irrigation, comprising:
a) sodium hypochlorite;
b) water;
the above aqueous formulation, in the form of a gel, being characterized in that it includes a viscosifying composition selected from:
1) amine oxides having general formula

wherein R<Sub>1</Sub> and R<Sub>2</Sub>, the same or different, are selected from methyl and ethyl; R<Sub>3</Sub> is an alkyl radical from C<Sub>10</Sub> to C<Sub>18</Sub>, preferably from C<Sub>12</Sub> to C<Sub>14</Sub>;
in combination with salts of alkaline or alkaline earth metals, preferably alkaline, of saturated fatty acids;
2) ethylene oxide-propylene oxide block copolymers;
3) polymers based on polyacrylic acid;
said aqueous formulation in the form of a gel being further characterized by a viscosity at 25°C of 800 to 6,000 cP, preferably from 1,000 to 2,500 cP.
The presentation is also described in glass (or other inert material) syringes of the aqueous formulation in the form of a gel of the present invention, the above syringes being used by odontological doctors in canal treatment. Said syringes can be equipped separately with a washing needle made of steel or plastic material, with a blunted tip.</p> |
