What is OPG?
OPG stands for Orthopantomography. It is a special method for obtaining radiographs of the teeth-bearing jaws, both upper and lower.

How is it different from regular X-ray machines?
A regular X-ray machine cannot take detailed pictures of the jaw-bones. An OPG machine is specially constructed so that it rotates around the jaw-bones, thus giving us an extremely good idea about the structure of the jaw bones. Yes, x-rays are used, but the method is totally different.

In what situations are they needed?
OPG x-rays are usually asked for by dentists, whether they be general dentists, orthodontists, oral surgeons or prosthodontists/implantologists. Because OPGs give a bird-eye view of the teeth and the adjacent bones, they are useful in a wide-variety of conditions including infections, tumors, congenital abnormalities, pre-implant evaluation and trauma.

Are they any risks?
Just as with x-rays elsewhere in the body, if a lady thinks she might be pregnant, an OPG can be avoided. No other risks exist.

Is any dye injected?
No

How much time does it take to get OPGs done?
Around 10 minutes.

How much does it cost?
On an average, Rs 250.

What is a cephalogram?
It is an x-ray of the face, obtained so that accurate measurements of the face can be performed.

What is its use?
Oral surgeons, orthodontists and prosthodontists need cephalograms prior to planning surgeries and teeth manipulation.

How much time does it take?
On an average, 20 minutes.

How much does it cost?
Between Rs 250 and Rs 400.
