Squid Ink in Dentistry?


Your future dentist visits could become a pleasant pain-free experience, and it’s all thanks to squids. A team of engineers from the University of California San Diego have developed an imaging method using squid ink and ultrasound to check for gum disease.

Dr. Ryne Johnson, prosthodontist and managing partner of Newton Wellesley Dental Partners has been promoting periodontal health for over 30 years.

If you’ve ever had to get your mouth checked for gum issues, you know that the current method to assess gum health involves inserting a periodontal probe’s metal hook in between your gums and teeth. Sometimes, depending on the dentist’s technique your pain tolerance, it hurts. The team’s method eliminates the need for probing — you simply need to gargle some food-grade squid ink mixed with water and cornstarch.

Squid ink is rich in melanin nanoparticles, and those get trapped in the pockets between your teeth and gums. When a dentist shines a laser onto your mouth, the nanoparticles swell and create pressure differences in the gum pockets. That’s where the ultrasound part of the imaging method comes in. Ultrasound can detect those pockets, so dentists can create a full map of your mouth.

The result shows how deep those pockets are, which indicate gum health. That’s why dentists stick a probe in those pockets to begin with — if they’re only one to three millimeters in depth, it means your gums are healthy. Anything deeper than that is a sign of gum disease, and the deeper those pockets are, the worse the issue is.

Problem is, the results of periodontal probing depend on the amount of pressure a dentist uses and the area he’s probing. He could be probing the wrong location or putting too little or too much pressure. Jesse Jokerst, the study’s senior author likened the periodontal probe to “examining a dark room with just a flashlight” wherein “you can only see one area at a time.” He said that their method is more like “flipping on all the light switches so you can see the entire room all at once,” leading to more accurate findings.

The engineers have big plans for their creation, starting with replacing the lasers in the method with more affordable LED lights. Their ultimate goal, however, is to create a mouthpiece that can instantly assess your gum health. They also want to get rid of the the squid ink concoction’s salty and bitter taste, though I’ll take than any day over painful probing.

So until the, Dr. Johnson reminds his patients to have regular, preventative visits with the hygienist. Brush and floss daily…remember, “you only have to clean the teeth you wish to keep”. For more blogs by Dr. Johnson or to contact him directly, visit www.NewtonWellesleyDentalPartners.org
