Q

what are the push and pull components of the theory of eruption

A

push

  • root form
  • pulp prolif
  • bone form
  • fluid pressure

pull

  • collagen contracts
  • fibroblast contrcation
  • fibroblast migration

16
Q

how is bone formation for eruption

A

bone forms under erupting tooth

17
Q

how is bone formation against eruption

A

root recited teeth erupt

bone fills in as tooth moves away

18
Q

how is hydrostatic pressure for eruption

A

`pd vasculature
cervical sympathetic stimulation
sympathectomy

19
Q

what is cervical sympathetic stimulation

A

vasoconstriction
cessation of eruption
reversible on cessation

20
Q

what is sympathectomy

A

vasodilation - inc tissue pressure

increase eruption rate

21
Q

how is hydrostatic pressure against eruption

A

root resected rodent incisor erupt normally

22
Q

what is the role of PDL fibres in eruption

A

rot resected exp
disrupt collagen formation
- no vit c ( collagen syn)
- lathyrogens (prevent cross

23
Q

so the result in PDL fibres in eruption is

A

slower eruption
no change in eruption
root fomraiotn continues
pollen sun affects eruption rte

24
Q

how are collagen contractions for eruption

A

principle oblique fibres

collagen can contract in vivo

25
Q

how are collagen contractions against eruption

A

no proof that collagen contracts in vivo

26
Q

how ar fibroblast migration/contration forces transmitted

A

along principle oblique fibres - scar tissue contraction

27
Q

how are fibroblasts migrtaion/contrcation for eruption

A

fibroblasts show motility
move cervically on eruption
colchine - reduces cell motility - retard eruption

28
Q

how are fibroblasts migration/contraction against eruption

A

PDL fibroblasts don’t have organelles for motility

no evidence can exert eruptive force

29
Q

what is the summary of eruption theories

A

multifactorial
not due to
- bone form or root form

due to

  • pull - PDL fibroblasts
  • push - hydrostatic pressure
30
Q

what are the series of events in bloodless eruption

A 
REE + oral mucosa
collagen disintegrates + REE prolif
fusion of oral epi and REE 
epi cell death 
epi pathway 
REE forms JE
31
Q

what is deciduous exfoliation

A

deciduous tooth resorbed = successional eruption

pressure on tooth - resorption

32
Q

what resorbs the deciduous teeth

A

resorbed by osteoclasts
- multinucleate ostecast cells
derived form monocytes

33
Q

what are som post eruptive movements

A

accommodate for growth
compensate for occlusal wear
accommodate approximal wear
following extraction of opposing tooth
