This post may sound a bit futuristic, but it is just one of the many ways nanotechnology can play a great role in impacting our lives. A study appearing in ACS Nano, describes a nano sized dental firm which could be used for bringing a diseased tooth back to life instead of leaving the tooth dead via a root canal.
The researchers have developed a multilayered, nano-sized film which contains a substance called alpha melanocyte stimulating hormone that could help regenerate dental pulp. The substance has anti-inflammatory properties and in the lab has been shown to fight inflammation in dental pulp fibroblasts. This has the consequences of being able to help revitalize damaged teeth and reduce the need for a root canal procedure which surely would please many.
