"The Effectiveness of a Sustainable Silver Nanoparticle Product in Stopping Caries in Children"

Albuquerque BB et al. Revista DCS. 2025, v.22, n.82. DOI: 10.54899/dcs.v22i82.3092 - Published 15/09/2025

Since 2019, Almacura has developed natural health products with scientific rigor, regulatory transparency, and a commitment to proven efficacy. We are the only colloidal silver brand with active ANVISA registration in Brazil.

In 2025, a group of 11 researchers - including PhD holders, doctoral students, and masters graduates in Dentistry - published a randomized double-blind clinical trial using Almacura® Colloidal Silver 40ppm as a mouthwash in children aged 6?9 in a Brazilian public school.

The study was conducted entirely independently. Almacura® did not participate in the design, execution, or analysis of results. Researchers chose the product for its accessible cost and formulation free of other active agents - which allowed them to evaluate the isolated action of silver nanoparticles.

Children in the group using Almacura® Colloidal Silver as a mouthwash showed a statistically significant reduction in cavity progression compared to the group using only fluoride toothpaste. Twice as many children showed improvement in the intervention group (14 children) compared to the control group (7 children).

The study followed CONSORT guidelines. The Almacura® 40ppm solution was chemically characterized by UV-Visible spectroscopy and transmission electron microscopy (STEM) at a Brazilian federal university's Chemistry department.


Our active ingredients

Each ingredient is selected for documented scientific efficacy and compatibility with a clean formulation - no unnecessary additives.

Colloidal Gold

Pure gold nanoparticles suspended in deionized water. Studied internationally for properties in regeneration and neuroprotection. External topical use.

Hydroxyapatite

Biomimetic mineral that makes up 97% of tooth enamel. Acts in remineralization and repair of micro-fissures in dental enamel. Fluoride alternative recognized by the international dental community.

Xylitol

Natural sweetener with proven action in cavity prevention. Inhibits bacterial adhesion to enamel and stimulates saliva production, contributing to oral pH balance.

Essential Oils

Exclusive blends of natural-origin essential oils - cedar, sandalwood, bergamot, orange blossom, lavender, and sage - selected for their aromatic properties and skin care benefits.

Ozonized Oil

Sunflower oil subjected to ozonization process. Studied for its properties in regeneration and topical skin care.
