Is CBCT more effective to detect healing periapical pathology?

Is CBCT more effective to detect healing periapical pathology?

Various studies have found CBCT to be clinically superior to IOPA radiography for the detection of periapical lesions [1, 4–6, 11]. Thus, CBCT scan may provide safer, faster, and more accurate method for differential diagnosis of the periapical lesions.

How are periapical lesions diagnosed?

Periapical lesions being the most frequently diagnosed apical pathology is mostly diagnosed using conventional radiography. This study showed that sensitivity and specificity of radiographs in detecting periapical lesions were reduced when compared with histology.

Does CBCT show infection?

The distinct advantage of this is being able to detect dental infections or abscesses, which appear as radiolucencies (dark holes) around the roots of a tooth at an earlier stage than the traditional periapical radiographs would show.

How is cone beam CT used to diagnose periapical disease?

Cone-beam CT provides detailed anatomy of the teeth and bones and can be used to evaluate periapical lesions in multiple planes, thus allowing improved detection and anatomic delineation of disease ( 13 – 15 ). However, it has poor soft-tissue contrast resolution and is therefore not ideal for evaluation of extraosseous lesions ( 11, 12 ).

How is radiography used to diagnose periapical lesions?

Panoramic radiography can provide an overview of the maxilla and mandible and is frequently combined with intraoral radiography to increase the sensitivity and specificity of diagnosis of periapical lesions, because panoramic radiographs alone are often subject to variability in interpretation ( 9, 10 ).

Which is the most common cause of periapical lesions?

According to one study, 78% of periapical lesions are the result of an infectious or inflammatory process, usually due to apical periodontal or pulpal disease ( 1 ). Recognition of the typical radiologic features of apical periodontal disease results in early referral and proper treatment.

Can a periapical Lucent be used as a diagnostic tool?

Although imaging findings for these lesions can include periapical lucent components, awareness of the varied secondary imaging features can aid the radiologist in developing an accurate differential diagnosis.
