In addition to digital radiography, we utilize special operating microscopes. Magnification and fiber optic illumination are helpful in aiding the doctors to see tiny details inside your tooth. Also, a video camera on the operating microscope can record images of your tooth to further document the doctor's findings.
This allows the doctors to electronically measure the length of each of the canals. This instrument, along with x-rays allows an extremely high level of accuracy in cleaning and shaping the canals and thus a higher rate of success with Endodontic treatment.
This instrument is mainly used while working through the microscope. With its extremely fine cutting tips which come in multiple angles, it allows the doctor to remove minimal tooth structure in a very precise location.
Until around 1996, the files used for Root Canal Treatment had not really changed all that much. The vast majority of Root Canals were performed using Stainless Steel Hand files. Now most are performed with Nickel Titanium Rotary Files. They are called Rotary Files because they are used in a slow speed electric hand piece (usually used at 300 rpm’s). There are multiple benefits of these files as compared to the old Stainless Steel Hand files, but the main benefit is that they allow the doctors to clean and shape the root canal system in a more effective manner. Our own Dr. Kaldestad has spent much time researching Rotary Files and actually has a U.S. Patent involving Rotary Files.
Digital radiographs are one of the newest X-ray techniques around. Digital X-rays have a significantly lower exposure to radiation than traditional X-rays that use film. With digital radiographs, the film is replaced with a flat electronic pad or sensor. The X-rays hit the pad the same way they hit the film. But instead of developing the film in a dark room, the image is electronically sent directly to a computer where the image appears on the screen. The image can then be stored on the computer and emailed to your referring doctor or printed out and saved for your records.
CBCT-Cone Beam Computed Tomography
The CBCT scanner uses an x-ray beam that is cone shaped to provide images of the structures of the skull, differentiating between tissue types such as bone, teeth, nerves and soft tissue. It uses a square 2-dimensional arrangement of detectors to capture the cone shaped beam and provide a volume of data. Reconstruction software is applied on the volumetric data to produce a 3-dimensional image of the area scanned. The CBCT is integrated into the office computer systems with images immediately available to doctor and patient. In Endodontics, the "Fine Field of View" is the best choice because of the small focus. It gives the highest resolution and needs the smallest amount of radiation. The scans are extremely accurate and free of magnification and distortion commonly associated with regular x-ray images. These images help the doctor analyze the orientation and position of critical structures like nerves, teeth roots, previous implants, the sinus and nose. The compact size of the machine fits in with every detail of the office designed to create a calming, caring environment that allows the patient to be as relaxed as possible.
