What are the two main types of radiographs used in dentistry?

The two main types of radiographs used in dentistry are intraoral and extraoral radiographs. Intraoral radiographs are taken with the film or sensor placed inside the mouth and are the most common type used to examine specific areas of the teeth and surrounding bone. They include various types, such as periapical and bitewing radiographs, which are essential for diagnosing conditions like decay, gum disease, and bone loss.

Extraoral radiographs, on the other hand, involve taking images with the film or sensor positioned outside the patient's mouth. These types of radiographs are useful for broader views and can help in assessing the overall structure of the jaw, the position of impacted teeth, and evaluating works with orthodontics.

Understanding the distinction between these two categories is fundamental in dentistry, as it influences the choice of imaging for diagnosis and treatment planning.
