Everything about teeth is important, they are one of the most essential part of our body, we used them when we eat, they grind the food into pieces so that it will be easy for our intestine to dissolve them and would create nutritional substances as a result of the process, they also help us speak properly, without them we will be having a hard time pronouncing the words we intended to say, it will create a funny sound instead. What we should know about teeth is that they are so strong that it could almost resist damage. They are made up of phosphorus,calcium and other minerals. The inner part of the tooth is called dentine. The hard, shiny layer is called the enamel.
Teeth are divided into two essential parts, the root to attach the tooth right on the jaw the other part is the crown, this is what you see mounting right at the gumline. Thou teeth are design to withstand pressure, they are still vulnerable to bacteria attack, they are infested with bacteria which slowly destroy them in the process. There are in fact different cases how teeth are being damage and are treated in different ways of course. Some of methods are invasive and worst even requires surgery procedure. However, there are experiments and new studies about treating you teeth in a noninvasive way.
The research, led by David J. Mooney, Robert P. Pinkas Family Professor of Bioengineering at the Harvard School of Engineering and Applied Sciences (SEAS), lays the foundation for a host of clinical applications in restorative dentistry and regenerative medicine more broadly, such as wound healing, bone regeneration, and more. The team used a low-power laser to trigger human dental stem cells to form dentin, the hard tissue that is similar to bone and makes up the bulk of teeth. Whats more, they outlined the precise molecular mechanism involved, and demonstrated its prowess using multiple laboratory and animal models.
A number of biologically active molecules, such as regulatory proteins called growth factors, can trigger stem cells to differentiate into different cell types. Current regeneration efforts require scientists to isolate stem cells from the body, manipulate them in a laboratory, and return them to the bodyefforts that face a host of regulatory and …
