The full form of OPG is Orthopantomogram.
An Orthopantomogram (OPG) is a panoramic dental X-ray of the upper and lower jaw. It provides a flattened two-dimensional view of a half-circle from ear to ear. OPGs are commonly used by dentists and oral surgeons to visualize teeth, bone, and other structures in the oral cavity and surrounding skeletal areas. It's an extraoral radiograph focused around the mandibular focal trough.
Here's a breakdown:
- Ortho-: Relating to straightness or correctness, in this context referring to the alignment of teeth.
- Panto-: Relating to everything or all.
- -gram: A recording or picture.
OPGs are useful for:
- Assessing impacted teeth
- Evaluating bone levels related to periodontal disease
- Detecting cysts, tumors, and other abnormalities
- Planning for dental implants
- Evaluating temporomandibular joint (TMJ) disorders
Unlike intraoral radiographs (X-rays taken inside the mouth), OPGs provide a broader view and require specialized equipment.
