Summary
Computed tomography (CT) reveals differences in radicular cyst growth patterns. Maxillary cysts cause bone expansion, while mandibular cysts grow without it, potentially delaying diagnosis.
Area of Science:
- Oral and Maxillofacial Radiology
- Dental Pathology
- Medical Imaging
Background:
- Radicular cysts are common inflammatory jaw cysts.
- Computed tomography (CT) provides detailed anatomical information.
- Understanding cyst morphology aids diagnosis and treatment planning.
Purpose of the Study:
- To evaluate computed tomography (CT) findings of radicular cysts.
- To analyze cyst location, size, and surrounding bone condition.
- To correlate CT findings with clinical symptoms.
Main Methods:
- Retrospective analysis of 146 histopathologically confirmed radicular cyst cases.
- CT examination data from 2012-2014.
- Measurement of mesiodistal and buccolingual diameters and assessment of bone changes.
Main Results:
- Maxillary radicular cysts were larger and showed more bone expansion than mandibular cysts.
- Mandibular cysts exhibited a higher mesiodistal to buccolingual diameter ratio.
- Lesion size and perilesional radiolucency correlated with symptom severity in the maxilla.
Conclusions:
- Maxillary radicular cysts cause bone expansion in multiple directions.
- Mandibular radicular cysts primarily expand mesiodistally without significant bone expansion.
- Delayed detection of mandibular cysts may occur due to less pronounced symptoms and bone changes.

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Biology is a natural science that studies life and living organisms, including their structure, function, development, interactions, evolution, distribution, and taxonomy. The field's scope is extensive and divided into several specialized disciplines, such as anatomy, physiology, ethology, genetics, and many more. All living things share a few key traits, including cellular organization, heritable genetic material and the ability to adapt/evolve, metabolism to regulate energy needs, the...

7.9K
When a force is applied parallel to the top surface of a solid, it resists the applied force due to the internal frictional forces between the layers of the solid known as shearing resistance. However, when the force is removed, the shearing forces restore the original shape of the solid. Other deformation forces also cause temporary changes in shape if the forces are not beyond a threshold magnitude. Solids tend to retain their shape, making the study of their rest and motion easier. Beyond...

Fluids differ from solids primarily in their molecular structure and stress response. Solids have tightly packed molecules with strong intermolecular forces, maintaining their shape and resisting deformation. In contrast, fluids have molecules spaced farther apart with weaker forces, allowing them to flow and deform easily.
Fluids, which include both liquids and gases, are substances that deform continuously under shearing stress. For example, water and oil are liquids with molecules that can...

The Bipolar Junction Transistor (BJT), specifically in a common-emitter configuration, exhibits distinct current-voltage characteristics crucial for understanding its behavior in electronic circuits. These characteristics are established through experimental measurements of voltage and current relationships.
For input characteristics, the base-emitter voltage is varied, maintaining a constant collector-emitter voltage. This setup reveals a Shockley-type dependence of the collector current on...
