Digital panoramic imaging can reveal the mandibular canal, crucial for dental implants. Bone density in the alveolar region influences how clearly the mandibular canal is depicted, aiding treatment planning.
Area of Science:
- Dentistry
- Radiology
- Oral Implantology
Background:
- Accurate imaging of the mandibular canal is vital for successful dental implant placement in the mandible.
- Digital panoramic radiography and multislice computed tomography (MSCT) are common imaging modalities used in dental diagnostics.
Purpose of the Study:
- To investigate the correlation between the visibility of the mandibular canal on digital panoramic images and the cancellous bone density.
- To assess how bone density affects the depiction of the mandibular canal in the context of dental implant planning.
Main Methods:
- Twenty-three patients with planned mandibular molar region implants were included.
- The mandibular canal's depiction in digital panoramic images was categorized into three types.
- Cancellous bone density at implant sites was quantified using average pixel values from MSCT scans.
Main Results:
- A significantly higher mean pixel value (indicating greater bone density) was observed where the mandibular canal was visible.
- Conversely, areas where the mandibular canal was not clearly depicted showed lower bone density.
Conclusions:
- The study demonstrates a relationship between cancellous bone density and the depiction of the mandibular canal in digital panoramic images.
- Bone density in the alveolar region is a key factor influencing the radiographic appearance of the mandibular canal, impacting implant treatment planning.

Spongy 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...
Compact Bone
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...
Bone Structure
Gross Anatomy of Bone
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 adults, it...
Bone as Supporting Connective Tissue
Bone Matrix
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is similar to the matrix material found in other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue. The inorganic matrix consists of mineral salts— mostly calcium salts— that give the...
Cranial 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...
