Karten in diesem Stapel (18)
- 1What is pulp cavity and what is it composed of?-Pulp chamber and root canal(soft tissue)
- Composed of: odontoblasts, fibroblasts - 2Pathway of vessels-Leave pulp via: apical foramina, apical ramification and lateral canal
- 3What is intracellular ground substance-Transparent, colourless
-Fills space between fibres and cells
-Rich in proteoglycans, glycoprotiens and water - 4What are odontoblasts responsible forSecretion of dentin and formation of dentinal tubule
- 5What are fibroblasts responsible forMost prevalent in pulp
Forms and maintains pulp extracellular matrix.
Contains type 1 and 3 collagen
There are also non-collagenous protiens - 6What are the other cells present- Macrophages, DC
-In close proximity to endothelial cells there are pericytes - 7pULP INNERVATIONA-bta:5%
A delt: 15
C-fibres: rest - 8What is Rashkow's nervous plexusAfter leaving the
Rashkow´s nervous
plexus(located in coronal pulp just beneath odontoblast layer), fibres lose their
wrapping and terminate
as free nerve endings at
the odontoblast layer and
pulpal border of dentin. - 9Pathway of root infection1. If protective layers(enamel and cementum) are lost, dentine and pulp is exposed
2. Bacteria enter via dentinal tubules(this increases dentine permeability and reduces dentine thickness)
3. Travels to pulp and its then compromised, defense mechanism impaired
4. pulp undergoes inflammation, infection and necrosis - 10What is reversible pulpitis-Reversible inflmmation
-Pulp stimulation is uncomfortable(sharp, quick pain)
-Removal of stimulus releives discomfort - 11Symptomatic irreversible pulpitis-Intermittent/spontaneous pain
-Prolongerd pain episode if exposed to thermal stimuli(esp, cold) even after removal
-Pain can be sharp/dull, localised, diffuse or referred
-Visible cahnge in radiograph is thickening of periodontal ligament - 12What is asymptomatic irreverisble pulpitis-Vital inflammed pulp incapable of healing
-No symptoms - 13Pulp necorissi characteristicsUnresponsibe to test
No blood supply
Nerve are nonfunctional
Next step after symptomac/asymptomatic irreversible pulpitis(progresses to periradicular tissue)
I heat applied for extended period of time it may react
Radiograph: thickening of pdl, and periapical radiolucent lesion - 14What are the apical diseasesSympotmatic apical periodontitis
Asymptomatic apical periodontitis
Acute apical abscess
Chronic apical abscess - 15Symptomatoic apical periodontitisInflammation of the
apical periodontium, producing clinical symptoms(nful response to biting or percussion or
palpation.
✓ The radiograph or image of the tooth will typically
exhibit at least a widened periodontal ligament space
and may or may not show an apical radiolucency
associated with one or all of the root - 16asymptomatic apical periodontitisThis condition is defined as inflammation and
destruction of the apical periodontium that is of
pulpal origin; it appears as an apical radiolucent
area and does not produce clinical symptoms
✓ The radiograph or image of the tooth will exhibit an
apical radiolucency.
✓ The tooth is generally not sensitive to biting
pressure but may “feel different” to the patient on
percussion - 17Acute apical abscessThis condition is defined as an inflammatory reaction to pulpal infection and
necrosis characterized by rapid onset, spontaneous pain, tenderness of the
tooth to pressure, pus formation, and swelling of associated tissues.
✓ A tooth with an acute apical abscess will be acutely painful to biting pressure,
percussion, and palpation, varying degrees of mobility.
Swelling will be present intraorally and the facial tissues adjacent to the tooth will almost
always present with some degree of swelling.
✓ The radiograph or image can exhibit anything from a widened periodontal ligament space to
an apical radiolucency.
✓ The patient will frequently be febrile, and the cervical and submandibular lymph nodes may
exhibit tenderness to palpation - 18Chronic apical abscessThis condition is defined as an inflammatory reaction to pulpal infection and
necrosis characterized by gradual onset, little or no discomfort, and the
intermittent discharge of pus through an associated sinus tract.
✓ The radiograph or image will exhibit an apical radiolucency.
The tooth is not sensitive to biting pressure but can “feel different” to the patient on percussion.
✓ This entity is distinguished from asymptomatic apical periodontitis because it will exhibit intermittent drainage
through an associated sinus tract
