what is the most important part for hygienists concerning oral health?

the hard and soft tissues that support the teeth is:

what are the three components of periodontium?

where does cementum come from?

what component covers the entire root?

one end of attachment for the PDL is ___________ and the other is the alveolar bone

is cementum AVASCULAR or VASCULAR?

where does it get its nourishment?

cementum is _____ % mineralized, enamel is ____% mineralized and dentin is ______% mineralized

remember....the ameloblasts couldn't create enamel because they didn't have their _______, the ondontoblasts started laying ________ matrix

THE NEWLY FORMED DENTIN induced the cells of the ________ _____ to differentiate into ___________

Cementoblasts laid their _________ and some of the cementoblasts got caught in the matrix and became ___________

the ends of the PDL that have embedded themselves into the cementum

where the cementum and enamel meet

what are the three types of CEJs where they meet?

in overlap of the CEJ the cementum overlaps the enamel because:

what type of meeting of the CEJ may be mistaken with calculus?

which meet PERFECTLY in the middle?

when there is a space between the cementum and enamel, the underlying dentin is exposed, this is called:

which meeting type of the CEJ can cause dentin hypersensitivity?

what are the two different lines of cementum repair?

after cementum resorption, you can tell where the resorption stopped and started laying down new cementum, these are called:

just like Retzius lines with enamel and lines of Von Ebner with dentin, for cementum they are called:

name the two types of cementum

the first cementum to get laid down, no cementocytes is:

the last cementum to get laid down is:

which cementum gets laid at a quicker pace so the cementoblasts get stuck in it?

T/F the cementoblasts that DON'T get stuck migrate to the periphery of the cellular cementum and wait there until more cementum is needed.
True False

name three clinical considerations with cementum:

kind of like a clam and a grain of sand, the clam doesn't like it, spits on it and creates a pearl _________ are similar in cementum

cementicles: cementoblasts start to lay _________ around cellular ________ in the PDL

a cementicle can just float there or start to fuse with ________ as more is laid

what starts as debris or floating in the PDL?

clinical consideration that was laid down screwy and caused a spur of cementum to come off the CEJ, similar to enamel pearls

excessive production of cementum is which clinical consideration of cementum?

this clinical consideration results from occlusal trauma (clenching/grinding)
