Question 2

what is the process that drives the process of a cyst

Answer 2

hydrostatic fluid

Question 3

what presents once the cyst has removed the overlying bone

Answer 3

expansion of the mucosa

soft touch

fluctunate swelling

Question 4

wehn do cysts become symptomatic

Answer 4

when they are so large that they brach the bone and mucosa and opening is created such as a sinus which allows for infection to transmit
this when symptoms begin to show

Question 5

bony expansion will lead to what

Answer 5

egg shell cracking

paraesthseia

Question 7

tooth associated with cyst - hollow percussion note

Question 8

if you palpate and it is hard what does that mean

Answer 8

it means it is a slow growing cysts as the bone has been able to repair the bone to ward of the hydrostatic pressure

Answer 13

= inflammatory radicular cyst

Question 14

if the content of the biopsy cyst is thick and viscous

teeth or antrum

Weakening of bone
