Pulp Flashcards
What leads to formation of the dentine-pulp complex
dental papilla
……… …….. extend from the pulp towards the …….. and joint the ……. at the …… in the crown
dentinal tubules
periphery
enamel
DEJ
Dentinal sclerosis reduces the permeability of the …… ………
dentinal tubules
The hydrodynamic theory is the main mechanism for ……. …………
The rapid displacement of the ………. fluid within the …….. ……… induces deformation of the ………… process and ……….. the A-fibres leading to the transmission of the ………. signal
dentine sensitivity dentinal dentinal tubules odontoblastic activates nociceptive
What factors trigger dentinal fluid movement
cold/hot
osmolarity (sweet substances)
mechanical pressure (chewing)
The pulp produces …… forming the …….. and ……… structure during the ……….
dentin
coronal
radicular
odontogenesis
The pulp is a ………… and can induce sclerotic and …….. dentine formation
immunocompetent
tertiary
The inflammatory cascade elicited during the pulp defence can trigger the …….. …… that leads to apical …….. ……..
cytokine cascade
bone resorption
The pulp is a connective tissue, composition of dental pulp:
different cells
extracellular matrix (fibres + ground substance)
blood vessels
nerves
What are the two fibres of the dental pulp
type I collagen
type II collagen
Clinical significance: what is used to dissolve infected fibrous tissue in the pulp
milton solution (1% sodium hypochlorite)
Nerves of the dental pulp
maxillary + mandibular branches of trigeminal nerve
2 pulp fibres and %
