Claims

OCR 09WP 27 / 04 / 2569 1. A manufacturing process for a drug-replacement material for treating deep caries near the pulp, containing a mixture of substances... Neem extract is included. A. The preparation of polyethylene glycol paste involves the following steps:

1. Measure the ingredients to the required proportions according to the recipe. A.

2. Place polyethylene glycol 4000 in a temperature-controlled bath. (Water bath) at a temperature of 75 degrees Celsius (°C) until all the solution is dissolved, by performing the following steps: Stir slowly to reduce the formation of air bubbles.

3. Gradually add stearyl alcohol and stir until well combined with the polyethylene. Dissolve the lean glycol 4000 and continue stirring until the mixture is well combined and forms a smooth consistency. Same (congeal) A.4 Add glycerin to the mixture obtained in step A.3 and stir until it is homogeneous. The mixture obtained at this stage is called the oil phase.

5. Pour distilled water into the beaker containing sodium lauryl sulfate. It is dissolved (congealed) in a temperature-controlled water bath at 75°C. Celsius (degrees Celsius). Continue stirring until sodium lauryl sulfate (Sodium Lauryl The sulfate is completely dissolved (congealed), and the resulting mixture is called... The component that is characteristic of water (aqueous phase). A.

6. Stir the aqueous phase of the mixture at all times, pouring slowly. Add the oil-based components little by little, stirring continuously until... It is homogeneous (congeal) and then removed and stirred further outside the temperature-controlled water bath. Room temperature 7. Allow the substance to solidify at a temperature of 25-28 degrees Celsius for 30 minutes. The result will be... A white, shiny paste compound that resembles a snowflake. appearance) Where the polyethylene glycol paste formula is composed of... Polyethylene glycol, 20% by weight. Stearyl alcohol 37% by weight. Glycerin 30% by weight. Sodium lauryl sulfate (1% by weight) 12% distilled water by weight. B. Paste forming with zinc oxide powder by mixing zinc oxide with... Polyethylene glycol paste at a ratio of 10% by weight, zinc oxide paste will be obtained. It is cloudy white in color and has increased viscosity due to the polyethylene glycol paste. C. Preparation of drug substitute compounds for treating deep caries near the pulp chamber. It contains neem extract, specifically 1% by weight, mixed with... Zinc oxide paste obtained from step B.

2. A manufacturing process for a drug-replacement material for treating deep tooth caries near the pulp cavity, containing a mixture of... Neem extract, as per claim 1, whereby the usable neem extract is obtained from the neem tree species Azadirachta indica var. Prepared using the ethanol extraction method.

3. An alternative treatment material for deep caries near the pulp, containing neem extract. Under Claim Method 1 or 2.
