Panoramic X-rays

Panoramic X-rays (also known as Panorex^® or orthopantomograms) are wraparound photographs of the face and teeth. They offer a view that would otherwise be invisible to the naked eye. X-rays in general, expose hidden structures, such as wisdom teeth, reveal preliminary signs of cavities, and also show fractures and bone loss.

Panoramic X-rays are extraoral and simple to perform. Usually, dental X-rays involve the film being placed inside the mouth, but panoramic film is hidden inside a mechanism that rotates around the outside of the head.

Unlike bitewing X-rays that need to be taken every few years, panoramic X-rays are generally only taken on an as-needed basis. A panoramic X-ray is not conducted to give a detailed view of each tooth, but rather to provide a better view of the sinus areas, nasal areas and mandibular nerve. Panoramic X-rays are preferable to bitewing X-rays when a patient is in extreme pain, and when a sinus problem is suspected to have caused dental problems.

Panoramic X-rays are extremely versatile in dentistry, and are used to:

Assess patients with an extreme gag reflex.
Evaluate the progression of TMJ.
Expose cysts and abnormalities.
Expose impacted teeth.
Expose jawbone fractures.
Plan treatment (full and partial dentures, braces and implants).
Reveal gum disease and cavities.

How are panoramic X-rays taken?

The panoramic X-ray provides the dentist with an ear-to-ear two-dimensional view of both the upper and lower jaw. The most common uses for panoramic X-rays are to reveal the positioning of wisdom teeth and to check whether dental implants will affect the mandibular nerve (the nerve extending toward the lower lip).

The Panorex equipment consists of a rotating arm that holds the X-ray generator, and a moving film attachment that holds the pictures. The head is positioned between these two devices. The X-ray generator moves around the head taking pictures as orthogonally as possible. The positioning of the head and body is what determines how sharp, clear and useful the X-rays will be to the dentist. The pictures are magnified by as much as 30% to ensure that even the minutest detail will be noted.

Panoramic X-rays are an important diagnostic tool and are also valuable for planning future treatment. They are safer than other types of X-rays because less radiation enters the body.

Testimonials

In one word 'outstanding'. I have had dental services from Cambridge, Mass to Dallas, Texas in my life but I have never ever come across such a truly outstanding practice. Dr. Christopher Yoo, and his father Dr. Yoo Senior, are both outstanding professionals. They have created, trained, and nurtured an outstanding staff from the reception desk all the way to the operatories. I will have to use my calculator to count the number of times Dr. Yoo uses gentle and comforting words like "sir", "please", "thank you", "appreciate it", etc. When I am in the operatory, I have the honor and pleasure of being in a very refined and multitalented company of Dr. Yoo, who takes the time to explain and teach all aspects of his treatment and empower the patient to follow up and take care of their dental hygiene. I want to specially mention appreciation by Dr. Yoo's peers. My friend Dr. Kevin G. Murphy, Baltimore, who is a well regarded periodontal-prosthodontic practitioner thinks very highly of Dr. Yoo and he personally recommended that my wife and me to be under Dr. Yoo's general dentistry practice and care. Please convey this review and my thanks to Dr. Yoo and his staff.

This was my first visit to Dr. Yoo's clinic and I was very impressed with all aspects of the practice. When I called to make an appointment, I was scheduled for the very next day. The receptionist was gracious and very polite, both on the phone while making my appointment and when I arrived at the clinic. The person who referred me to Dr. Yoo had told me many things about the practice, so although I wasn't surprised, I was very impressed with the high-tech environment and the way it was used to make me both better informed and very comfortable during my initial examination and cleaning. Especially interesting was the digital imaging of my teeth and the camera tool that provided a real-time image of my individual teeth. All of these images were present on a screen that I could view while in the chair. Dr. Yoo was very personal, patient, and supportive, and took time to carefully explain his findings and recommendations. I highly recommend Dr. Yoo and his staff and look forward (really!) to my next visit.
