Dr. Michaels decided that she wanted to become a dentist and moved up to Boston for 4 years to complete dental school at Boston University. She then moved to New York City in 2020 to complete 2 years of a General Practice Residency in the Bronx, and then completed her 2 year Endodontic Residency at the prestigious Manhattan VA.

Dr. Michaels and her husband have very fond memories of Boston and NYC, but are excited to explore Columbus. Currently, they enjoy going on walks through German Village with their Goldendoodle, Bess!

State of the Art Technology

Central Ohio Root Canals is equipped with the latest technology and Dr. Subramanian is highly trained in the use of these available technologies to provide optimal care at the highest level to our patients.

Surgical Operating Microscope

Dr. Subramanian uses the microscope for all procedures in our practice. The microscope provides enhanced visibility and magnification with increased illumination to be able to provide care with the best possible outcomes. Operating microscopes are necessary to provide the highest level of care possible with significant advantages:
  • Magnified Image Increased Precision
  • Improved Illumination Improved Visualization

Magnified Image

Magnified Image

Microscopes provide 3x to 27x magnification with the ability to change views with a simple turn of a dial. Microscopes offer a deeper depth of field view and a wider field of view than traditional dental loupes.

Increased Precision

Increased Precision

The increased magnification allows the endodontist to access small, narrow canal opening without unnecessarily removing tooth structure. Debris that must be removed from the root canal before filling the root canal space is also more easily identified.

Improved Illumination

Improved Illumination

When magnification is used, the available light is spread out and the image appears darker. To compensate for this, an LED light is mounted directly on the microscope head and provides a bright, white light.

Improved Visualization

Improved Visualization

Endodontists can only treat what they can see. The microscope lens can be placed directly over the patient’s mouth without any additional discomfort.
