Review periapical X-ray and CBCT findings around a tooth root tip, including radiolucency, cortical thinning, sinus relationship, and root canal context in plain language.
A periapical lesion is a change around the tip of a tooth root. It may relate to infection, inflammation, prior root canal treatment, trauma, or other dental history. CBCT can show the finding in three dimensions and clarify which root is involved.
The most useful patient questions are practical: which tooth is involved, how large is the finding, is the sinus or cortical bone affected, and what follow-up does the dentist or endodontist recommend?
Periapical X-rays are often the first view, while CBCT adds depth when roots overlap or the sinus floor is close. For nearby dental topics, compare this page with root fracture CBCT signs, the periapical lesion CBCT guide and the dental CBCT reading guide.
Open your CBCT privately, note the involved tooth, then bring the scan and questions to a dentist or endodontist.
Open CBCT ViewerNot always. Imaging must be combined with symptoms, tooth vitality testing, dental history, and examination. CBCT localizes the finding but does not replace diagnosis by a dentist or endodontist.
CBCT can show depth, root involvement, sinus relationship, and cortical bone change more clearly than a single 2D X-ray, especially when anatomy overlaps.
No. AI explanation can help you understand the scan, but treatment decisions require clinical dental testing, symptoms, restorability assessment, and professional judgment.
