Study Looking To Develop Stronger Dental Fillings

Many that go to their nearest Easton dentist want to avoid having to get fillings, as they’re quite expensive, and can break. A team of researchers from Portland’s OHSU School of Dentistry is aware of how filling is currently, and have been working on creating a filling material that’s more sturdy that what’s currently available.

The team published their study in the journal, Scientific Reports, showing that they had a filling material that was twice as resistant to breakage than the standard material, thanks to the addition of thiourethane, used in protective coatings for cars and decks. On top of that, the team also developed an adhesive that’s 30% stronger following six months compared to the adhesive currently available on the market. The new adhesive and its capabilities was detailed  in another study, published in the Dental Materials journal.

These two combined allow for the creation of longer-lasting dental fillings.

One of the authors of the studies, in Scientific Reports and Dental Materials, Cermam Pfeifer, D.D.S., Ph.D., says that most dental restorations tend to last around 7 to 10 years before they break, either cracking under the pressure of chewing, or have gaps forming between them and the tooth, which then lets a new cavity form. This is an issue for any American and Easton dentist, as this leads to the tooth under the restoration to grow weaker over time, which may then end up leading to root canal damage, a lost tooth, or, the worst case-scenario, life-threatening infections.

Stronger dental materials, she explains, means that people don’t have to get their fillings repaired or replaced as often, saving not only money and energy, but also stops more serious problems from popping up and removing the necessity for more extensive treatments.

The adhesive described in the Dental Materials utilizes (Meth)acrylamides, a specific type of polymer, that’s more resistant to damage in water, bacteria, as well as oral enzymes compared to the adhesives currently used in dentistry. Meanwhile, the composite material described in Scientific Reports utilizes thiourethane, which is much more resilient to chewing.

Pfeifer was one of the co-leaders in the studies, alongside Jack Ferracane, Ph.D., Chair and Professor of Restorative Dentistry.
