OTTAWA--(Marketwire - Aug 25, 2012) - Visiting the dentist to have an old filling replaced may one day be a thing of the past, according to new dental technology developed by the University of Maryland's School of Dentistry.
Researchers from the university have created a new cavity filling system that claims to not only kill all lingering bacteria, but also promote re-growth of the tooth structure that weakened due to decay.
Instead of just limiting decay like today's fillings, the new fillings will control harmful bacteria in the mouth.
When dealing with a cavity, today's dental professionals drill out as much of the decayed section as they can to remove as much bacteria as possible to prevent it from spreading. The problem is that they are only able to remove so many bacteria.
The solution to this problem includes insertion of antibacterial agents in primers and adhesives after the tooth has been prepped. Once the majority of the bacteria has been cleared out, the dentist inserts primers. The dentist then applies the adhesives to the cavity to secure the filling in place. The new antibacterial components will eliminate any remaining bacteria.
"It is common for today's fillings to fail because the decay still remains under the restoration," said Dr. Pamela Li, an Ottawa dentist. "This new research could change the way we view fillings."
The new fillings are constructed of nanoparticles of calcium phosphate, which gives key minerals to the teeth. The fillings also have a high PH level, which reduces acid production.
The new antibacterial fillings are expected to last five to 10 years longer than today's filling, but additional research is still needed.
"Even though this research is still a long way from being FDA approved, it's wonderful to know scientists are working to prevent decay in the mouth," the smile makeover professional who uses Invisalign said. "Although a focus on prevention is much needed, scientists may put dentists out of a job one day."
