Investigation of coronoid process hyperplasia using Levandoski analysis on panoramic radiographs
1Department of Oral and Maxillofacial Radiology, Giresun University, Giresun 28200, Turkey. suledelil92@gmail.com.
Background:
The diagnosis of coronoid process hyperplasia (CPH) is usually based on symptoms and radiological imaging. Because of its similar symptoms, it can be confused with temporomandibular joint diseases. Therefore, an objective and reproducible way of diagnosis should be determined.
Aim:
To investigate CPH using Levandoski analysis on panoramic radiographs to determine its prevalence.
Methods:
A total of 300 panoramic radiograph images (600 coronoid processes) were examined. Having measured the Condyle-Gonion (Cd-Go) and Coronoid-Gonion (Cor-Go) distances, the Cor-Go:Cd-Go ratio was calculated for the left and right sides of each image.
Results:
There was a statistically significant difference in Cd-Go and Cor-Go distances between male and female participants (P < 0.001). There was no statistically significant relationship between Cor-Go:Cd-Go ratios and gender (P > 0.05).
Conclusion:
Cd-Go and Cor-Go distances were statistically significantly increased in males on both the left and right sides. The ratio of Cor-Go:Cd-Go was preserved in both genders. The prevalence of CPH was found to be 0.3%.

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...

Magnetic Resonance Imaging (MRI) and Ventilation Perfusion Scans are two radiological investigations that offer detailed diagnostic images of the body, particularly lung structures.
MRI
MRI uses magnetic fields and radiofrequency signals to distinguish between normal and abnormal tissues. This technology provides a more detailed diagnostic image than CT scans, enabling it to characterize pulmonary nodules, stage bronchogenic carcinoma, and evaluate inflammatory activity in...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
