Acellular extrinsic fiber cementum is for anchorage Cellular intrinsic fiber cementum is for adaptation and repair Mixed fiber cementum is for adaptation..
The accentuated incremental lines that can indicate the trauma of birth are called Harris lines. These are horizontal lines that can be seen on X-rays of bones and are believed to represent growth arrest episodes during early childhood due to illness or malnutrition.

Cellular cementum contains cementocytes embedded within lacunae, while acellular cementum does not contain cells. Acellular cementum is primarily found at the cervical portion of teeth, while cellular cementum is more abundant at the apical portion. Cellular cementum has a higher turnover rate due to the presence of cementoblasts and cementoclasts, while acellular cementum forms slower and is more resistant to resorption.
It is called the cementum and it's the third hardest substance in the human body, after the enamel and the dentin.
Cementum holds the teeth in the jaw, just as cement would.
cementum Covers the root of the tooth. The primary function for the cementum is to anchor the tooth to the bony socket with the attachments of the priodontal ligaments.
Cementum.
Cementum is the outside covering of the roots of human teeth. The crown of the tooth is covered in enamel.
Cementum.
The area of the tooth where the cementum meets the enamel is called the cementoenamel junction or CEJ for short.
