1When do odontoblasts and ameloblasts appear?
- Acap stage
- Bbell stage
- Cbud
- Dinitiation
2Which of the following is true
- APlexus of Rashkow is the dense network of myelinated nerve fibers
- BThe Zone of Weil is devoid of capillaries and nerves
- CPulp has propioception
- DPulp contains nociceptors, unmyelinated mechano-receptors, and myelinated C fibers
- EThin, unmyelinated fibers with a neurolemma control blood flow and pressure at the dental pulp
3Which of the following are principle fibers?
- AHorizontal group
- BCircular group
- CTranseptal group
- Dall of the above
- EHorizontal and transeptal
4Odontoblasts are derived from ectomesenchymal cells. In life, they are later replaced by undifferentiated stem cells of the pulp.
- AT/T
- BT/F
- CF/T
- DF/F
5Which of the following is false
- Aβ-catenin is required in odontoblasts for tooth root formation
- BLateral canals can be found in the apical 1/3rd of the root
- COdontoblasts are more columnar at the root
- DThere are more dentinal tubules in the crown
- EDentinal tubules are more innervated in the crown
6After placement of a dental implant, which of the following fibers will be present after healing?
- Adentogingival and circular
- Balveologingival and dentoperiosteal
- Ccircular and transeptal
- Dcircular and alveologingival
- Ealveolar crest and circular
7Most dentin matrix secretion is when .25-.5mm of dentin thickness remains. TGF B1 and TGF B3 are required molecular stimuli for secretion.
- AT/T
- BT/F
- CF/T
- DF/F
8Which of the following is false about pulp circulation and blood flow?
- APulp flow is increased by inflammation
- BPulp flow is increased by CGRP and SP
- CPulp flow is decreased by epinephrine
- DPulp flow is increased by initiation of pulpal necrosis
- EPulp flow is decreased by orthognathic surgery
9Odontoblasts are NOT...
- APseudostratified in pulp chamber
- BColumnar at the pulp chamber
- CCuboidal at the radicular pulp
- DSquamous at the radicular pulp
- Ea single layer at the junction of the pulp and the dentin
10Which of the following is false?
- AUnmyelinated C fibers are pain fibers with a high threshold
- BA beta are large, myelinated, and have a low-threshold
- CA delta are small and have a high threshold.
- DA beta feel innocuous toch and mechanical sensation
- EA delta feels pain, cold, some heat
11Which of the following is false?
- AIrreversible pulpitis is often predicted by spontaneous pain
- BBest predictor of post-endodontic treatment plan is pre-treatment pain
- CLocal anesthetics do not work as well when dental pulp is inflamed
- DThe best test to determine vital versus necrotic pulp is heat followed by electric pulse.
- EIrreversible pulpitis can be asymptomatic
12Central sensitization can result in referred pain that affects an entire arch. This can be due to both an increased release of neurotransmitters and increased response to neurotransmitters.
- AT/T
- BT/F
- CF/T
- DF/F
13The cell bodies of the nerves of the pulp can be found in the trigeminal ganglia. The main mediator of pulpitis is peripherally located, unmyelinated C-fibers.
- AT/T
- BT/F
- CF/T
- DF/F
