Innovation by Brazilian dentists could help to make root canal treatment less painful for patients.
According to the Financial Times, the field of dentistry is especially advanced in the South American country, despite its status as a developing country.
"It's an environment that encourages original research," Ultradent spokesperson Luiz Abreu commented.
He added that the company has created two new products that could soon be rolled out worldwide, one of which helps healthcare professionals to assess the amount of work needed for each root canal treatment.
The second is a set of files that is designed to make the procedure less intrusive.
Mr Abreu said researchers are interested in "combining more sophisticated materials with less invasive techniques".
The Virtual Medical Centre recently said that root canal treatment and other dental procedures need not be painful if they are caught early and recommended that patients should always go for regular check-ups.
