A complete or "full mouth series" of periapical x-rays may consist of 17 or more radiographs.
Periapical x-rays show the condition of the teeth and roots and the overall composition of bones that support the teeth. These x-rays are an essential part of any dental examination.
Periapcial x-rays help dentists to detect the presence of abnormalities in the roots and crowns of the teeth and locate abscesses, fistulas, and cysts.
Dentists suggest time frames for periapical x-ray evaluations by evaluating the dental health of the patient. While some patients need radiographs taken on a fairly frequent basis, others who maintain good oral hygiene at home may be able go for more than a year.
