OBJECTIVE To present two cases of osteochondritis dissecans (OCD) in temporomandibular joints (TMJs) evaluated by panoramic radiography and cone-beam computed tomography (CBCT). CLINICAL PRESENTATION AND INTERVENTION Two patients were referred to the Oral and Maxillofacial Radiology Clinic with pain, preauricular tenderness on the TMJ region and limitation of mandibular movements. An earlier ...

The efferent vessel of hepatocellular carcinoma (HCC) and the mechanism and pathogenesis of the high frequency of intrahepatic metastasis in HCC has not yet been clarified. Three hundred ninety-three resected specimens of HCC were examined for tumor thrombosis in the portal vein and the hepatic vein: 231 tumors < or = 5 cm in diameter were examined for the relationship between mode of tumor spr...

A 23-year-old female patient presented with diffuse swelling causing intermittent pain involving the left side of face that had been present for over 10 years. Extra-oral examination revealed expansile lesions in maxilla and mandible, appeared mixed radiolucent-radiopaque on panoramic radiography. The maxillary lesion resulted opacification sinus. mandible trabecular bony changes larger radiolu...

We read with interest the editorial by Chung discussing advantages of radio-guided occult lesion localisation (ROLL) over other commonly used pre-operative localisation techniques for breast tumours. While the results from our audited introduction of ROLL support the conclusion that ROLL is “a simple and effective solution for guiding the excision of impalpable breast lesions”, two important dr...

Selectively excavated carious lesions remain radiographically detectable. Radiopaque tagging could resolve the resulting diagnostic uncertainty. We aimed to evaluate if tagging depends on lesions depths, is antibacterial, or affects dentin bond-strengths. Artificial lesions (depth-range: 152-682 μm, n = 34/group) were induced in human dentin samples, evaluated using wavelength-independent micro...

A 14-year-old Black female was referred for management of an asymptomatic swelling in her right maxilla. The lesion measured 3cm across, was localised lateral to the right ala of the nose, felt bony hard in some areas and soft in others, and was continuous with the maxillary buccal plate. It occupied the right anterior vestibule but there was no palatal expansion. A panoramic radiograph showed ...

Subpontic osseous hyperplasia (SOH) is an ectopic growth of bone occurring on the edentulous ridge beneath a fixed partial denture. The aim of this article is to present three patients with SOH with long-term follow-up and to make a current overview of the literature. Presented maxillary SOH is the second case in the dental literature. Intraorally the lesions were bone-hard and painless swellin...
