Dental gel promotes use of dental drill

PARIS: According to french researches, the dentist's drill may be thing of the past for smaller cavities, thanks to a new dental gel that promotes regeneration of teeth.

A team of scientists from the National Institute for Health and Medical Research in Paris say the gel, containing melanocyte-stimulating hormone (commonly known as MSH) can help decaying teeth grow back by prompting cells to start multiplying. In laboratory studies, they tested to see if melanocyte-stimulating hormone, could stimulate tooth growth. The cells replace the cells in the decayed tissue & the tooth is restored to a healthy tooth. The team then mixed MSH with a chemical called poly-L-glutamic acid to create a gel, which they rubbed on cells taken from extracted human teeth.

The Researchers investigated the regenerative properties of the hormone & found it effective in producing new cells. In another experiment, they rubbed the gel on the teeth of mice with dental cavities. And the scientists said it took less than one month to restore teeth back to their original state.“There are a lot of exciting developments in this field, of which this is one,” said professor Damien Walmsley, the British Dental Association's scientific adviser. “It looks promising, but we will 've to wait for the results to come back from clinical trials & its use will be restricted to treating small areas of dental decay.”

In addition to replacing traditional fillings, the gel may end the need for the dentist's drill in certain circumstances, but the treatment is not suitable for severe decay.The gel is slated to undergo more testing, but it could be showing up in your dentist’s office in the next three to five years, according to the report. The findings are published in the American Chemical Society journal.
