CBCT Interpretation Airway Sleep

CBCT can identify odontogenic cysts (dentigerous, radicular, keratocysts), benign tumors (ameloblastoma, odontoma, central giant cell granuloma), bone lesions (fibrous dysplasia, ossifying fibroma), and malignant changes within the jawbone. It also detects osteomyelitis, osteonecrosis, and traumatic bone cysts.

CBCT can identify characteristics that raise suspicion for malignancy — irregular borders, cortical destruction, rapid growth between scans — but a definitive cancer diagnosis requires histopathologic examination through biopsy. CBCT guides the biopsy by showing the best access point and the lesion's relationship to adjacent structures.

An incidental finding is a condition discovered on imaging performed for an unrelated reason. For example, a CBCT taken for implant planning might reveal a mucous retention cyst in the sinus, an impacted supernumerary tooth, or a periapical lesion on a tooth the patient had no symptoms from. All incidental findings at ADSC are documented and communicated to the patient and referring provider.

Treatment depends on the cyst type, size, and location. Small periapical cysts may resolve with root canal treatment. Larger cysts typically require surgical enucleation — removal of the cyst lining — sometimes combined with bone grafting of the resulting defect. Odontogenic keratocysts have higher recurrence rates and may require more aggressive surgical margins.

If the dark area (radiolucency) is not clearly a normal anatomical structure and does not correspond to an obvious dental cause such as a periapical infection, CBCT is the next diagnostic step. It will show the true size, borders, and characteristics of the lesion in three dimensions, which significantly narrows the differential diagnosis.

Yes. Osteomyelitis (bone infection) produces characteristic CBCT findings including moth-eaten bone destruction, periosteal new bone formation, sequestra (islands of dead bone), and involucrum formation. These findings guide antibiotic therapy decisions and surgical debridement planning.

An odontoma is a benign tumor composed of dental tissue — essentially a disorganized mass of tooth-like structures. On CBCT, compound odontomas appear as a cluster of small tooth-like structures, while complex odontomas appear as a dense, calcified mass. They are common incidental findings and are usually surgically removed because they can block eruption of permanent teeth.

Monitoring intervals depend on the suspected diagnosis and the lesion's behavior. A stable-appearing benign cyst might be reimaged at 6 to 12 months, then annually if unchanged. A lesion with concerning features may be reimaged sooner or biopsied rather than monitored. Your doctor will establish a follow-up schedule based on the specific findings.

Yes. Dentigerous cysts around unerupted teeth, odontomas blocking tooth eruption, and central giant cell granulomas all occur in pediatric patients. CBCT imaging in children uses reduced dose protocols appropriate for smaller anatomy and is reserved for cases where two-dimensional imaging is insufficient.

The CBCT data guides the biopsy approach — the surgeon knows the exact location, depth, and extent of the lesion before making an incision. The tissue sample is sent to an oral pathology laboratory for microscopic examination. Results typically return within one to two weeks, and the treatment plan is finalized based on the pathologic diagnosis.

Yes. MRONJ, which can occur in patients taking bisphosphonates or certain cancer medications, produces characteristic CBCT findings including sclerotic bone, sequestra, persistent extraction sockets that fail to heal, and thickened lamina dura. CBCT helps stage the disease and plan surgical management when indicated.

No. Many jaw lesions are cysts (fluid-filled cavities), infections, benign reactive conditions, or normal anatomical variants mistaken for pathology on two-dimensional imaging. CBCT helps distinguish pathology from normal anatomy and helps categorize true lesions by their radiographic characteristics before biopsy confirms the diagnosis.

If CBCT findings and biopsy results suggest malignancy, ADSC coordinates referral to an appropriate oncology or oral and maxillofacial surgery team, shares all imaging and clinical data, and continues to provide supportive dental care throughout treatment. Timely referral is prioritized.

Pathology-focused interpretation evaluates lesion characteristics systematically — borders, internal structure, effect on surrounding anatomy, growth pattern. Routine dental CBCT might focus on available bone for implants or canal anatomy for root canals. The reading framework is different because the clinical question is different.

Yes. While periodontal bone loss is typically assessed with periapical radiographs and clinical probing, CBCT shows the three-dimensional pattern of bone destruction around teeth — including buccal and lingual defects invisible on conventional films. This is particularly useful for planning regenerative periodontal procedures and evaluating furcation involvement in molars.
