Dentigerous cysts are the most common developmental cysts of the jaws, most frequently associated with impacted mandibular third molar teeth. Dentigerous cysts around supernumerary teeth, however, account for 5% of all dentigerous cysts, with most developing around a mesiodens in the anterior maxilla. This report describes two cases of a dentigerous cyst associated with an impacted mesiodens. Both of the patients complained of swelling in the maxillary anterior region. Radiographic examination revealed an impacted mesiodens surrounded by a large corticated radiolucency in both cases. A provisional diagnosis of infected odontogenic cyst was made. The cysts were enucleated with the removal of the mesiodens in the two cases. Histopathological examination confirmed the diagnosis of infected dentigerous cyst associated with an impacted mesiodens in both cases. The patients remained asymptomatic, and no complications were noted.

To conclude, digital panoramic radiographs had good sensitivity and high specificity in detecting CCAAP. If properly trained, dentists can detect such plaques and can refer patients to physician for timely medical treatment.

Objectives: The objective of the study was to determine whether digital panoramic radiography is a reliable method to detect calcified carotid artery atheromatous plaques (CCAAP) as compared to ultrasonography.Study design: Digital panoramic radiographs were obtained from 50 patients who also underwent carotid ultrasound examination. The images were interpreted by trained maxillofacial radiologist for the presence or absence of calcified atheromatous plaques. The extent of carotid calcification on carotid ultrasonography was determined by a trained sonologist which was considered as gold standard assessment.Results: Digital panoramic radiographs had sensitivity of 76% and specificity of 98.66% in determining calcified carotid artery atheromatous plaques. There was a high level of agreement between diagnoses, with a kappa value of 0.8. Conclusion:To conclude, digital panoramic radiographs had good sensitivity and high specificity in detecting calcified carotid artery atheromatous plaques. If properly trained, dentists can detect such plaques and can refer patients to physician for timely medical treatment.

Arteriovenous malformations are extremely rare conditions in that can result from abnormalities in the structure of blood vessels, which may be potentially fatal. A 30-year-old female patient visited our hospital with a complaint of swelling on the right maxillary posterior gingiva along with the large port-wine stain on right side of face. On clinical examination, the swelling was compressible and pulsatile. Radiographic examination revealed a lytic lesion of maxilla. Diagnostic angiography revealed a high-flow arteriovenous malformation of maxilla which was treated by selective transarterial embolization of maxillary artery using polyvinyl alcohol particles.
