The cementum is derived from the investing layer of the dental follicle. Over the surface of the cementum, there lies a thin layer about 3-5 µm in thickness that is not calcified called the ...

Cementum is primarily present in two varieties, the acellular extrinsic fiber cementum (AEFC, acellular or primary cementum) and cellular intrinsic fiber cementum (CIFC, cellular or secondary ...

The cementum is comprised of 55% organic and 45% inorganic compounds. The organic portion of cementum consists primarily of Type I collagen and protein polysaccharides.

Similar to tree rings, the cementum tissue of mammalian teeth form growth lines in its microstructure. The cementum also acts as a biological archive of major life events, this new research shows.

Teeth consist of three main hard tissues: enamel, dentin and cementum. Cementum, which covers the tooth root, develops characteristic "rings" that grow each year as we age—much like tree rings.

Teeth consist of three main hard tissues: enamel, dentine and cementum. Cementum, which covers the tooth root, develops characteristic "rings" that grow each year as we age - much like tree rings.

The main culprit for sensitivity is the tooth's enamel wearing down. "A very common cause of tooth sensitivity is the exposure of dentin and cementum caused by loss of soft tissue support surrounding ...
