Mandibular anterior nutrient canals in periapical radiography in relation to hypertension.

Background: Hypertension (HTN) is the most commonly encountered systemic disease in general population. Nutrient canals contain blood vessels and nerves that mostly appear in the anterior mandibular region. Nutrient canals are not detected in radiographs of all patients, and their normalcy is controversial by many investigators.

The relation of pericoronal third molar follicle dimension and bcl-2/ki-67 expression: An immunohistochemical study.

Background: Most common impacted teeth are the mandibular third molars and decision about extraction of them is usually controversial. The presence of pericoronal pathologic changes is an acceptable reason for removal of impacted teeth. Differences in the proliferation rate and apoptosis of odontogenic epithelial cells may influence on the formation of odontogenic epithelial lesions.

Diagnostic accuracy of ultrasonic examination in suspected craniosynostosis among infants.

The current study was performed to assess the diagnostic accuracy of ultrasound compared to CT scan as a gold standard in the diagnosis of craniosynostosis. 44 infants (17 girls) under 1 year old, clinically suspected to have craniosynostosis, were first sonographically examined by a pediatric radiologist and were later referred to another blinded pediatric radiologist to examine CT scan with 3D reconstructed images of skull. Sensitivity, specificity, positive and negative predictive values of ultrasound versus CT scan were 96.

Diagnostic Accuracy of Ultrasonic Examination in Suspected CraniosynostosisAmong Infants.

Ultrasound is a non-invasive, available, low-cost modality and is free of side effects. The current study has been performed to assess the diagnostic accuracy of ultrasound compared to CT scan as a gold standard in the diagnosis of craniosynostosis. 44 infants (17 girls) under 1 year old, clinically suspected to have craniosynostosis, were first sonographically examined by a pediatric radiologist and were later referred to another pediatric radiologist to examine CT scan with 3D reconstructed images of skull as gold standard modality.
