Cementocytes vs. Osteocytes: What's the Difference?

Edited by Harlon Moss || By Janet White || Published on January 1, 2024
Cementocytes are cells embedded in the cementum of teeth. Osteocytes are mature bone cells embedded in the matrix of bones.

Key Differences

Cementocytes are specialized cells found within the dental cementum, playing a role in maintaining tooth integrity. Osteocytes, on the other hand, are mature bone cells found within the bone matrix, crucial for bone maintenance and mineral homeostasis.
The primary function of cementocytes is to maintain the cementum, which helps anchor teeth to the jaw. Osteocytes have a broader role in regulating bone density and structure, signaling bone formation and resorption.
Cementocytes are less numerous and have a more limited distribution, confined to the teeth. In contrast, osteocytes are the most abundant cell type in bone tissue, distributed throughout the bone matrix.
Cementocytes have a limited capacity for regeneration and repair, while osteocytes play an active role in bone remodeling and healing, responding to mechanical stress and damage.
The environment of cementocytes is relatively static, confined to the dental structure. Osteocytes, however, are part of a dynamic bone environment, constantly responding to physiological changes and stresses.

Cementocytes and Osteocytes Definitions


Cells in the cementum of teeth.
Cementocytes help to maintain the health of the tooth's root.


Mature bone cells.
Osteocytes are essential for maintaining bone health and strength.


Have limited regenerative abilities.
Cementocytes, unlike some other dental cells, have limited capacity for regeneration.


Regulate bone density.
Osteocytes help balance bone formation and resorption, impacting bone density.


Involved in tooth anchoring.
Cementocytes play a role in anchoring teeth to the jawbone.


Abundant throughout bones.
As the most abundant cells in bones, osteocytes play a crucial role in skeletal health.


Less numerous than other dental cells.
Despite being less numerous, cementocytes are vital for tooth integrity.


Active in bone remodeling.
Osteocytes respond to mechanical stress, aiding in bone remodeling and repair.


Confined to the dental structure.
Cementocytes are found only within the dental cementum.


Respond to physiological changes.
Osteocytes adapt to changes in the body, ensuring bone integrity.

Osteocytes play an active role in bone remodeling and can aid in bone regeneration.

Are cementocytes as abundant as osteocytes?

No, cementocytes are less abundant and are confined to the teeth.

How are osteocytes distributed in the bone?

Osteocytes are distributed throughout the bone matrix and are the most abundant bone cells.

How do osteocytes respond to mechanical stress?

Osteocytes respond to mechanical stress by signaling bone remodeling and repair processes.

What do osteocytes do?

Osteocytes regulate bone density and structure and are involved in bone remodeling.

Is the function of cementocytes limited to the teeth?

Yes, the function of cementocytes is confined to the dental cementum and tooth anchoring.

Do cementocytes regenerate like bone cells?

Cementocytes have much more limited regenerative capabilities compared to bone cells.

What are cementocytes?

Cementocytes are cells located within the dental cementum of teeth.

What happens when cementocytes are damaged?

Damage to cementocytes can affect tooth anchoring and overall dental health.

How do cementocytes differ from other dental cells?

Cementocytes are unique in their location and function related to tooth anchoring and cementum maintenance.

What role do osteocytes play in bone health?

Can cementocytes be targeted in dental treatments?

While limited, understanding cementocytes can aid in developing specific dental treatments.

What is the lifespan of osteocytes?

Osteocytes have a long lifespan, often as long as the bone exists.

Are osteocytes involved in bone diseases?

Yes, changes in osteocyte function can be involved in various bone diseases, including osteoporosis.

Are cementocytes involved in anchoring teeth?

Yes, cementocytes help in anchoring teeth to the jawbone.

Can osteocytes detect changes in bone stress?

Yes, osteocytes can detect changes in mechanical stress and adapt bone remodeling accordingly.
