Endodontics popularly known as root canal treatment is a department of dentistry that deals with the diagnosis and treatment of pulp and periapical tissues. The endodontist removes dead or infected pulp from the chamber and root canals, widens and disinfects the canals, and then tightly fills them with special material. By using the microscope, the endodontist can perfectly clean hard-to-reach places and can see every detail accurately, which is why he can best perform the treatment.
