    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
