Dental Robot Doesn’t Need Human Assistance

Since developing a surgical robot, engineers across the globe have been pushing the limits of machines in medicine. This Chinese dental robot can perform implant surgery without any human assistance.

The implants were fitted to within a margin of error of 0.2-0.3mm, reaching the required standard for this kind of operation.

The robot addresses the shortage of dental technicians as well as frequent surgical errors. China imports roughly 1 million implants annually, which hardly satisfies the 400 million patients needing new teeth. The Fourth Military Medical University’s hospital takes care of 3D printing dentures.

[Dental staff] programmed the robot to move into the correct position to carry out the operation, and determined the movements, angle and depth needed to fit the new teeth inside a cavity in the patient’s mouth.

The robot adjusts to patients’ movement, which is definitely a plus. It also makes the experience a lot less intimidating, knowing your gums won’t be in for a prickly surprise. It seems surgeons are in for some serious competition.

Green Tea Extract Can Treat Tooth Sensitivity

If there is one part of the body that we too often neglect, it’s our pearly whites. Forget to brush them? It’s not the end of the world. After all, they can now be 3D printed. But if you’d prefer to keep them, at least invest in an automatic toothbrush. Because treatment for aches and rotting can sometimes break the bank, doctors from Wuhan University are working on alternatives. Now, green tea extract can treat tooth sensitivity.

The compound is called epigallocatechin-3-gallate (ECGC), and it is the most active polyphenol in green tea. Previous studies have shown that this compound can effectively battle S. mutans.

The scientists encapsulated this mix into so-called mesoporous silica nanoparticles (MSN).

To break it down, MSNs can effectively resist cavity-inducing acids and are superior in strength. They are the Justice League of dentin.

The material “significantly [inhibited] the formation and growth of S. mutans biofilm on the dentin surface,”

The application technique is called confocal laser scanning microscopy, which is just about as easy to say as that ridiculous town in Wales. All tongue twisters aside, we can show more enthusiasm for the green tea industry. Although I do remain on the fence about tea lattes from Starbucks.
