A new study suggests the damage caused by a tooth root can be a sign of an underlying condition.
The study published in the journal Current Biology on June 2 suggests the nerve injury caused by the procedure may be more common than previously thought.
Dr. Mark Feltgen, an emergency medicine physician at the University of Minnesota Health System, is one of the study’s authors.
“It’s the first time we have found a connection between the tooth root and the nerve damage,” he told ABC News.
“This is an area that has been underreported.”
A patient was treated for a toothroot injury.
“The patient had a nerve injury that was quite severe and not treated in a timely manner,” Feltgens study author Dr. Jia-Li Liu, a physician at Tufts University School of Medicine, said.
“What the authors found is that the nerve could not heal.”
The study was conducted at the Mayo Clinic, in Rochester, Minn., and is the first to report the findings of this study.
Liu said she was interested in understanding why the nerve is damaged in the first place, but she wasn’t expecting to find a connection with tooth root.
The findings, she said, are important because they suggest that a person may need to have their tooth root removed for more serious nerve injury, or a condition called nerve root canal stenosis.
Liu’s research team examined bone samples from three dogs, all of whom had a tooth that was surgically removed.
They examined the nerves, and found that the nerves had been damaged, or they had a thin layer of bone on the surface that was not able to heal properly.
The nerves had a thickness of only about 0.1 percent, the researchers reported.
The thick layer of the nerve tissue prevented healing.
The researchers used a microscope to view the nerves and determined that they had damaged the nerve cell membranes.
They also found that nerve tissue had been removed from one of these dogs.
The team did not identify the dogs that had the nerve root surgery.
“If we can get a better idea of how the nerve cells regenerate in the bone, we can determine whether we can develop new treatment options,” Liu said.
The scientists also looked at a tumor sample from one dog that had a damaged nerve and did not have the nerve surgery.
They found that bone from this dog had the same thinning layer of nerve tissue that the dogs had.
“We see that we have a lot of tissue that has not regenerated,” Liu told ABC.
“There is a thinning that we are seeing in the nerve that is a precursor to healing.”
The researchers also examined a sample of bone from a dog that was able to regenerate, but did not recover the nerve, Liu said, because it had been in a person for about two years.
The tissue was different.
It had the thickness of 1.5 percent of the tissue, which was less than half the thickness as the nerves.
“These two dogs have both a tooth and a nerve,” Liu explained.
The nerve in question is found in the tooth of the dog with the tooth removed, and the tissue from the dog that didn’t have the root surgery is found around the bone of the tooth.
The bone in question was from a puppy, but it wasn’t part of the original surgery.
The animals had their tooth removed to treat a tumor, Liu explained, and they have been able to use the nerve in the tissue to help them walk again.
Liu and her team did their study after finding out that the root canal was the cause of the tumor in a different dog.
“I was a little bit concerned because there was some confusion as to whether the root could be the cause or whether it was the tumor,” Liu admitted.
“But we were able to identify it as the root and we were pretty confident that it was just a tumor.
So we decided that we need to see if there are other tumors and if so, whether the tumor was caused by this root.”
The scientists found that this dog also had a tumor that was in the root, but they didn’t know why.
Liu, who is also an emergency physician, said that her team has already started to see other patients who have a similar case.
“They all have this same type of cancer,” she said.
A lot of people don’t realize that when they go to a dentist, they may need a root canal to get the root removed.
“So we are really seeing a lot more people going to a root removal site and they need to be careful,” Liu added.
