Answer
|
|
Matrix formation in cementum is faster in
|
Cellular cementum, owing to presence of cementoblast and
cementocytes |
|
The cementocytic process interconnect with each other through
|
gap junctions
|
|
incremental lines of Salter are rich in
|
Osteopontin
|
|
The first formed cementum is
|
Acellular extrinsic fibre cementum
|
|
The type of cementum that has no role in attachment is
|
Intrinsic fibre cementum
|
|
What is cellular mixed stratified cementum
|
In the apical region and the furcations, acellular extrinsic and
cellular intrinsic fibre type of cementum presents in alternating layers, which is called cellular mixed stratified cementum |
|
The varied origin of mixed cementum can be best demonstrated by
|
Polarized light, that show the different orientation in
different shades |
|
The proteins absent in acellular extrinsic fibre cementum are
|
Dentin sialoprotein, fibronectin and tenascin. And deficient in
lumican, versican, decorin, biglycan and fibromodulin |
|
In the cervical region of tooth, loss of reduced enamel
epithelium leads to |
Formation of afibrillar cementum
|
|
The number of fibers in acellular extrinsic fibres is
|
30,000 per sq mm
