Cementum at the root is described as what?

The root cementum is primarily described as cellular in nature. This means that it contains living cells, specifically cementocytes, which are embedded within the cementum matrix. These cells play a significant role in the maintenance, repair, and remodeling of the cementum as they react to stimuli and changes within the oral environment. This cellular structure allows for the adaptation of the cementum in response to physiological stresses and functional demands, making it essential for the anchorage of periodontal fibers that attach teeth to the alveolar bone.

Understanding that cementum is cellular highlights its dynamic nature compared to acellular cementum, which does not contain living cells and is primarily found in certain locations such as the cervical area of teeth. This distinction is significant in veterinary dentistry, as it underscores how different parts of the tooth respond to injury and repair mechanisms. Additionally, recognizing the cellular nature of root cementum is vital when considering treatment options for dental disease and periodontal health in small animals.
