How do bacteria exist in the root canal space in endodisease
as a biofilm
How do the bacteria in endo disease show resistance
the AB may fail to penetrate the biofilm
AB may be trapped and destroyed by enzymes
AB may not be active against non-growing microorganisms
expression of biofilm-specific resistance genes
stress response to hostile environmental conditions
What are features of apical periodontitis
→ Chronic poly-microbial infection
→ Stimulation of host response
Connective tissue destruction
What are features of periradicular disease
→ Highly prevalent
→ Significant morbidity (tooth loss/severe infection)
→ Substantial healthcare burden to NHS
→ Focus of infection/inflammation?
What are the clinical objectives of RCT
→ Remove canal contents
→ Eliminate infection
→ Remember multiple options exist for management of endo disease
What is the aim of the endo-restorative interface
→ To provide an environment that allows healing of periradicular tissues so that the tooth is retained as a functional unit in the dental arch
In a radiograph if the root canal disappears what does this mean
canal division
If in a radiograph there is a thickening of the space in periradicular areas other than the apical region what does this mean
lateral and accessory canals
If in the radiograph there is a knob like appearance what does this mean
curvature
If there is an unusual presence of vertical lines in the radiographs what does this mean
gross concavities of the root surface
In electric pulp testing what nerve is stimulated first
a delta - lower stimulation threshold
What does the vascular supply of the tooth consist of
main supply arterioles
supply capillary network
terminal capillary network
venular network
