Microaggregates can Improve Anesthesia Used by Dentists

Exame - Researchers in Brazil and Texas have begun testing a new strategy to increase the effectiveness of topical dental anesthesia in humans .

The theme was featured on Thursday morning (9/21) during the FAPESP Week Nebraska-Texas symposium in the United States.

"A very deep injection is needed to numb the area being treated or to block a nerve. And this injection is usually painful, since conventional topical anesthesia methods have little penetration and effectiveness, "Gill said.
