Science and Technology Desk: Upma Guha is an associate professor at the University of Nebraska Medical Center (UNMC) College of Dentistry in the United States . Since 2015, he has been teaching in various universities in the United States. In addition to research and teaching, he served as the clinic director of the UNMC College of Dentistry for a long time.

Upma Guha is researching dental materials, digital dentistry and artificial intelligence in dentistry. He has obtained dental degree from Bangladesh Dental College. Masters from University of North Carolina Chapel Hill Adams School of Dentistry, USA.

He said, there are many countries, the people of those countries understand the meaning of teeth when they have teeth. It is said that toothache is the second most painful pain in the world. The first is the pain of childbirth. The outermost structure of our teeth, which we call 'enamel', has no nerves to feel.

It is the strongest organ in the human body. Harder than bone. It takes seven to eight years for the enamel of a tooth to decay. But still people don't understand, they have a problem. Then when the pain starts, go to the doctor. But it didn't happen in one day. It has decayed for a long time and has come to this state.

Let me tell you another thing. In our country, if an artist is asked to draw a picture of a grandmother or grandmother, they will most likely draw a grandmother or grandmother with blistered teeth. Because, we think, at the age of 70, it is normal for one to lose four-five or all teeth. But scientifically speaking, it is not correct. If you take good care of your teeth, you will not fall out even at the age of 70-80. Old people don't have teeth because of lack of dental care in our country.

Many people are talking about AI in Bangladesh too, work is going on. But in the US it's not the technology of the future, it's the present. AI is being used everywhere from the education sector. The main idea of ​​my research is to use AI as a helper. We x-ray patients. People used to observe them for so long. But I can do this data monitoring much faster with AI. At the end, of course, a person will analyze it again, whether everything is right or not; That means I will definitely have to check it again.

Now we do one more thing with AI. Suppose a patient comes to us for the first time. Then we look at the health of his teeth, gums and gums. There is usually a joint (pair) of the teeth with the gums to see this health. But when the gums are destroyed, a gap (gap) is formed between the gums and the teeth. How much or how deep that gap is, has to be checked. It is very time consuming.

291 students are permanently involved in traffic control!

It is necessary to go to the root of each tooth and examine it little by little. Here we use AI. You visually say how big the gap is and the AI ​​takes note of it. Later you just check. AI generates it in table form in very less time. But we check it later to see if it is correct or not. In the future, this treatment can be done completely with the help of robots. It could also be that I treated the teeth of a Bangladeshi from the US with a robotic arm. I hope that will happen in the future.
