Summary
Osseous dysplasias (OD) are idiopathic changes in the jawbone where normal bone is replaced by fibrous tissue and mineralized deposits. These non-neoplastic lesions are classified as fibro-osseous lesions of the head and neck.
Area of Science:
- Oral pathology
- Bone biology
- Head and neck pathology
Background:
- Osseous dysplasias (OD), previously termed cemento-osseous dysplasias, represent idiopathic alterations within the alveolar process of the jaw.
- These conditions involve the replacement of normal bone architecture by fibroblasts and collagen fibers, progressing to the formation of mineralized tissue and bone.
Purpose of the Study:
- To elucidate the nature and classification of osseous dysplasias.
- To provide a clear understanding of these fibro-osseous lesions within the current WHO framework.
Main Methods:
- Histopathological analysis of affected tissues.
- Review of current World Health Organization (WHO) classification criteria for bone-associated lesions.
Main Results:
- Osseous dysplasias are characterized by a biphasic process involving fibrous and mineralized tissue.
- The WHO classification designates ODs as non-neoplastic, fibro-osseous lesions.
Conclusions:
- Osseous dysplasias are distinct entities characterized by specific histopathological changes.
- Accurate classification within the WHO framework aids in diagnosis and management of these jawbone lesions.

1.2K
Radiological investigations, including X-rays and computed tomography (CT) scans, are critical for diagnosing and evaluating various medical conditions. These imaging techniques provide valuable insights into the body's internal structures, aiding in the detection of abnormalities, assessment of disease progression, and development of treatment strategies. This article delves into two primary radiological investigations, chest X-rays and CT scans, outlining their purpose, procedures, and...

01:03Finding the Center of Gravity
4.4K
The center of gravity of a body is an imaginary point where the body's total weight is assumed to be concentrated, and the body is perfectly balanced. The center of the mass of a body is a point at which the whole of the mass of the body appears to be concentrated. If the acceleration due to gravity, g, has the same value at all points on a body, its center of gravity is identical to its center of mass. The center of gravity of homogeneous bodies such as a sphere, cube, or rectangular plate...

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.

01:13Finding Electric Potential From Electric Field
5.7K
For a system of charges, it is easy to calculate the system's potential because potential is a scalar quantity. However, in some instances where calculating the electric field is more straightforward than finding the potential, the electric field is used to calculate the system's potential. For a positive charge, the electric field is radially outward, and the potential is positive at any finite distance from the positive charge. In such an electric field, the motion away from the...

01:24Finding Volume Using Cross-Sectional Area

For solids whose cross-sectional areas vary in a predictable way, volume can be determined by integrating these areas along an axis perpendicular to the slices. This approach is particularly useful for polyhedral solids, where classical geometric formulas may not be immediately applicable. A tetrahedron provides a clear example of how cross-sectional integration can be applied to a three-dimensional object with continuously changing geometry.Consider a tetrahedron with height h and a base that...
