ABE WRITTEN BOARDS - SPRING 2025
Andreasen 1985/1986 probability of transient apical breakdown due to lunation injury -
Answer -4.2%
Sunqvist 1998 - Most common bacteria isolate of persisting periradicular lesion after
unsuccessful NSRCT - Answer -Gram-positive, Enterococcus Faecalis
Wysocki 1981 - Least likely unilocular lesion between roots of Max Incisor and Canine -
Answer -Fissural cyst in glubulomaxillary region
Waltimo 1997 IEJ - incidence of yeast in failed NSRCT - Answer -7%
Dentinal Sensitivity Definition - Answer -Transient pain arising from exposed dentine,
typically a response to chemical, thermal, tactile or osmotic stimuli
Dentinal sensitivity - Prevalence - Answer -8-35% Gilliam
Hydrodynamic theory - Brannstrom - Answer -Inward or outward movement of fluid
through dentinal tubules activates sensory nerve fibers in the dentine or pulp to produce
pain>
Fluid movement can be a response to dehydration, osmotic changes, mechanical
probing or thermal changes.
Rapid outward movement most likely to illicit pain (drilling/cold)
Inward movement (heat) takes longer to develop pain
Density of dentinal tubules - Komabayashi - Answer -13,700 - 32,300 per mm2
Tubule dentistry increased by factor of 2 from outer to inner surface
SEM diameter is dentine tubule is 2-5 micrometers
Al-Hiyasat - Pulp cap tx outcome b/t mechanical and caries exposure. - Answer -
Mechanical exposure success rate: 92%
Caries exposure success rate: 33%
3 year follow up
Cox 1985 - - Answer -Effect of material placed against pulp - Intact remaining dentine
was more important than the pulp capping material itself.
AAE/AAOMR - Limited FOV vs Large FOV - Answer -Limited FOV:
