Oral Bacteria Leave Mark Inside Mouth

There may be a new way to distinguish a person’s identity.

Bacteria in the mouth—especially bacteria located in gums—can tell you more about a person then could ever be imagined. The remnants are similar to that of a fingerprint, meaning it’s possible to tell some people apart based on these remnants. And yes, you can even tell a person’s ethnicity.

Scientists managed to pinpoint 400 different species of bacteria in the mouth based on about 100 participants in the study. The ethnicities involved included blacks, whites, Chinese and Latinos.

The results indicated that just 2 percent of bacterial species are seen in all people. The exact numbers, high or low, showed some similarities among people of the same ethnic group.

Oral Cancer Cases may be Rising

The oral cancer problem may be getting worse.

Statistics indicate that there was an increase of 1,000 oral cancer cases in the United Kingdom during the past year. Since 2000, the number of oral cancer cases has doubled, particularly among men.

In 2011, 2,500 people in the United Kingdom died from oral cancer. The alarming part is that survival rates are not increasing the way they are with other forms of cancer. This stems from the fact that many oral cancer cases are diagnosed when it’s too late to turn back the effects from cancer.

Teeth Developed Thanks to Evolution

Evolutionary copycats eventually developed tooth-like structures independent from other vertebrates.

The new revelation appears in Nature and was discovered by the University of Bristol in the United Kingdom. Previous conventional wisdom suggested that our skeleton and its characteristic bony tissues stemmed from predators that were called conodonts. The skeleton, however, came from our mud-slurping relatives who developed a type of bony armor to defend themselves against predators.

The researchers analyzed the tooth-like skeleton of conodonts by utilizing advanced x-ray systems. The results indicated that the tooth-like structures came from the conodonts’ evolutionary lineage instead of a common ancestor between vertebrates and them.

Pets Need Dental Care Too

Humans aren’t the only ones who need to maintain dental care.

Pets need but don’t often receive the requisite dental care to have solid oral health. As a result, many studies indicate that dogs have some type of gum disease. This stems from the fact most dog owners pay little to no attention to cleaning their dog’s teeth on a regular basis.

Gum disease can prevent a dog from being able to chew properly, in addition to causing pain and systemic health issues.

Women More Disgusted by Dental Treatment than Men

Women are more easily grossed out at the dentist than men, according to a recent study. The study indicated that, on average, women are six times more disgusted at the dentist than men are.

The information was determined after having men and women view photographs of dental treatment and procedures.

Women with a dental phobia found it challenging to keep their emotions in check when viewing these images. For people without a dental phobia, however, men and women had similar reactions to the photographs.
