Dental pulp is a connective tissue but it varies for different patient..first of all,it
contained within the tooth and enclosed by dentine , the toothhas little space
inside the tooth containing the pulp,surrounded from all parts by dentin .it's
closed by rigid walls
but if your enamel is lost or injured,it wont be replaced.,the doctor jusy repeated
the previous sentence in Arabic..nothing more; so this is how the tooth defend
itself;by growing new layer of dentine inside.
the part before slide 16 the nerve signal ( sayal 3a9abi) is not transmitted by
nerves ,odontoplastic processes act as receptors for impulses from dentin
(dentine. (dr said it is important to remember this point)
Slide 16 :the end of paragraph : well here a very important part was missing..the
doctor said that in general he doesn't ask about the differet type of cholinergic
endings .
Dentinal tubule : tubules inside the dentin containing fluid ,sometimes these fluid
move,sometimes when eating sweety things..fluid move performing pressure to
equivalent the osmotic pressure
slide 12,13,14 before talking about the mouse. : sympathetic supply of the head
and neck region ;consequently if we remove the cervical gangilion we notice a
decrease in cholinergic materials ,they deducted that some of the sympathetic
nerves are cholinergic .
Just 8 lines below the previous part the doctor explains something about the
teeth formation, that the dental papilla in enamel organ will form dentin and
pulpits very important to have good amount on blood pressure to regulate the
synthesis of enamel and dentine.
[Slide 15 : and there's an increase rate of tooth eruption ,when the parysympathetic
was removed the pressure increased ,also parasympathetic is important in matainn the
pressure in pulp,because increase of pressure inside the pulp will cause increase in
tooth eruption ..One of the mechanisms of tooth eruption is pulpal pressure
Slide 21 : nerve fibers and odontoblastic processes are pulled by hydronamic
force,when digging the cavity the device you use looses water and this will
damage the dentine causing odontoblastic processes to be pulled ..by
hydrodynamic force,these are secreted from pulpal tissue.tob3n damaging nerve
fibres and killing of odontoblasts will cause pain in dentine.this is one.tob3n
when u have small injury,when the odontoblasts layer's damage is slightwhen
the damage is slight the pulp will make a dentine layer under th e dentine layer
