| Cementum is a product of the | show 🗑
|
||||
| show | Acellular, cellular
🗑
|
||||
| show | doesnt contain cementocytes; forms slower than cellular cementum
🗑
|
||||
| What cementum forms faster: cellular or acellular? | show 🗑
|
||||
| When forming cementum cementoblasts start where... and move where | show 🗑
|
||||
| Cementoblasts adhere to the DCJ and move outward toward the PDL As they move outward they leave behind a cemental matrix in layers called... | show 🗑
|
||||
| show | cervical 1/3 of the root; it is also found on the outer surface of cellular cementum in the very most apical portion of the root
🗑
|
||||
| Characterize cellular cementum | show 🗑
|
||||
| show | When cementoblasts surround themselves with the matrix that calcifies, the cells are then called cementocytes
🗑
|
||||
| Space where cementocyte sits in is called | show 🗑
|
||||
| show | cytoplasmic processes
🗑
|
||||
| Cytoplasmic processes | show 🗑
|
||||
| show | canaliculi
🗑
|

| Canaliculi | show 🗑
|
||||
| show | in the apical 2/3 of the tooth
🗑
|
||||
| show | Lamella
🗑
|
||||
| show | Cementum is thicker in areas of cellular cementum
🗑
|
||||
| Statement: Cellular cementum can sometimes be found on the surface of acellular cementum. | show 🗑
|
||||
| show | layer of cementum that has not completely calcified
🗑
|
||||
| show | eventually it is located on the outer surface of root in PDL next to cementum
🗑
|
||||
| In what field of dentistry is cementum important | show 🗑
|
||||
| show | Due to hypocalcified (low calcified) nature it is not readily absorbed. Cementum is avascular which may account for it’s resistance to resorption – making orthodontic tooth movement possible
🗑
|

| One of the main responsibilities of cementum is | show 🗑
|
||||
| How long is cementum layed down | show 🗑
|
||||
| show | True
🗑
|
||||
| show | to a certain extent by the cementoblasts in the PDL (buidling more cementum)
🗑
|
||||
| If severe pressure applied to tooth from a blow or too rapid orthodontic tooth movement, repair may not be possible and root resorption may occur by odontoclasts | show 🗑
|
||||
| show | cemental hyperplasia; production of excessive cementum; etiology unlnown; extraction would be difficult
🗑

🗑
|
||||
| Cemental/ root caries often seen in | show 🗑
|
||||
| show | If recession has occurred and root surface exposed to oral fluids and the accompanying bacteria, cemental caries can occur
Root surfaces that have been exposed due to recession are also likely to experience abrasion and/or dentinal hypersensitivity
🗑

|
||||
| show | avascularity (lack of blood vessels)
🗑
