Summary
Dense bone islands (DBI) are common, affecting 3.2% of patients. These benign bone lesions predominantly occur in young females in the mandibular premolar region, with no significant root resorption observed.
Area of Science:
- Oral and Maxillofacial Radiology
- Dental Pathology
Background:
- Dense bone islands (DBI) are asymptomatic, benign bone lesions.
- Radiographically, they appear as well-defined radiopacities without a radiolucent rim.
- Understanding their prevalence and characteristics is crucial for accurate diagnosis.
Purpose of the Study:
- To determine the prevalence of dense bone islands (DBI).
- To investigate the relationship between DBI and patient demographics (age, sex).
- To identify the predominant location, amount, shape, and root resorption correlation of DBIs.
Main Methods:
- Retrospective review of panoramic images from 4581 patients aged 14 years and above.
- Data collected from Case Western Reserve University School of Dental Medicine between January 2014 and May 2015.
Main Results:
- A prevalence of 3.2% (147 out of 4581 patients) was found for DBI.
- DBI showed a statistically significant predilection for females.
- The most affected age group was 15-24 years, with a predominant location in the mandibular right premolar apical region and a round shape.
Conclusions:
- Dense bone islands are radiopaque lesions without a radiolucent rim.
- DBI can occur at any age and location, with a higher prevalence in females.
- While root resorption was observed in a few cases, no deleterious effects were noted on follow-up.

Compact Bone

Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Spongy Bone
8.4K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Bone Disorders
5.6K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Gross Anatomy of Bone
10.0K
The two main features of a long bone are the diaphysis and the epiphysis.
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The walls of the diaphysis are composed of dense and hard compact bone made of numerous osteons — the functional unit of the compact bone. The hollow region in the diaphysis is called the medullary cavity, which harbors the bone marrow. In infants and children, this marrow cavity is filled with red marrow, whereas in...

Osteoclasts in Bone Remodeling
4.4K
Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.
