Intra Oral Periapical Radiographs
These can either be taken conventionally or by the help of RVG (RADIO VISUO GRAPHY). RVG offers certain benefits over conventional X-Rays such as images can be stored, manipulated, and corrected for under- and overexposures.
But one of the most important is reduction in dose of exposure to radiation. IOPA radiographs cannot accurately reflect the bone morphology buccally andlingually but they provide useful information on interproximal bone levels.
They also provide information on the root length, root proximity, and presence of periapical lesions and estimates of remaining alveolar bone. It helps in diagnosing minute pathologic changes in the periodontium which could interfere with implant placement.
