Nano-Coated Synthetic Enamel with Properties Near Natural Teeth Coating Developed

A collaborative effort from prestigious institutes developed a study for a new teeth enamel alternative. The new artificial device was constructed with similar properties found in a natural tooth, according to the research.

The study describes how the team created the synthetic solution and its quality compared with its natural counterpart.

Synthetic Enamel Made from Hydroxyapatite Nanowires

Tooth decay has been one of the common health problems pestering humans since ancient times. The issue was recorded thousands of years before dentistry even existed.

Tooth decay solutions are being administered today, but these modern advantages lack the function to fully rebuild the damaged or lost enamel. With the new research, experts created a new model that could be the last answer against challenging replenishments of the enamel on the human teeth.

Previous studies confirmed that while the human enamel contains a hardened structure, it is also slightly elastic. This is because, at a closer look, the enamels are made of tiny calcium rods complicated, similar to what we see on a case full of pencils.

The new paper attempts to recreate the natural human enamel into a synthetic medium through AIP-coated (arc ion plating) hydroxyapatite nanowires. These components are aligned parallel to each other by using a freezing technique and polyvinyl alcohol.

The enamels created through the experiments were tested to various shapes, especially on human teeth, to check how effective and qualified it is for clinical use.

The synthetic enamels were found to contain high stiffness rates, compacted with strong resistance, and elastic. Through a series of side-by-side comparisons, researchers found that artificial enamel performed better than natural enamel.

According to a report by PhysOrg, further studies must be met for the team to formulate a better synthetic enamel that could withstand extremities' present and passing through the human mouth.

Enamel Reconstruction vs. Tooth Decay

The authors aim their project towards becoming a clinical-grade device that could be used in dentistry operations and made available on the market.

If the artificial enamel passes the required qualifications, the experts said that the concept could exceed the field of dentistry, allowing other industries to support their respective works.

The synthetic enamels may be effective as a coat for pacemakers, reconstruct remains for archaeology and paleontology studies, and repair damages on bones that have eroded or were caused by another medical disease.

Tooth decay roots from the permanent damage inflicted to the hard surfaces of the teeth. Many factors can induce the issue, including bacteria, sugar-rich beverages, snacks, and neglect of hygiene.

Tooth decay is also known as cavities. It is among the health problems that could manifest in many people regardless of age.

Untreated tooth decays could result in deeper and larger issues on the mouth. Usually, the condition leads to a severe infection, toothache, and ultimately, tooth loss. Regular brushing of teeth, flossing, and periodic visit to a dentist could protect the teeth and enamel from weakening and damage.

The study was published in Science, titled "Multiscale engineered artificial tooth enamel."
