Wähle eine der folgenden:

  • Plexus of Rashkow is the dense network of myelinated nerve fibers

  • The Zone of Weil is devoid of capillaries and nerves

  • Pulp has propioception

  • Pulp contains nociceptors, unmyelinated mechano-receptors, and myelinated C fibers

Wähle eine der folgenden:

  • T/T

  • T/F

  • F/T

  • F/F

Erklärung

Frage 5 von 13

1

Which of the following is false

Wähle eine der folgenden:

  • β-catenin is required in odontoblasts for tooth root formation

  • Lateral canals can be found in the apical 1/3rd of the root

  • Odontoblasts are more columnar at the root

  • There are more dentinal tubules in the crown

  • Dentinal tubules are more innervated in the crown

Erklärung

Frage 6 von 13

1

After placement of a dental implant, which of the following fibers will be present after healing?

Wähle eine der folgenden:

  • dentogingival and circular

  • alveologingival and dentoperiosteal

  • circular and transeptal

  • circular and alveologingival

  • alveolar crest and circular

Erklärung

Most dentin matrix secretion is when .25-.5mm of dentin thickness remains. TGF B1 and TGF B3 are required molecular stimuli for secretion.

Wähle eine der folgenden:

  • T/T

  • T/F

  • F/T

Erklärung

Frage 8 von 13

1

Which of the following is false about pulp circulation and blood flow?

Wähle eine der folgenden:

  • Pulp flow is increased by inflammation

  • Pulp flow is increased by CGRP and SP

  • Pulp flow is decreased by epinephrine

  • Pulp flow is increased by initiation of pulpal necrosis

  • Pulp flow is decreased by orthognathic surgery

Erklärung

Frage 9 von 13

1

Odontoblasts are NOT...

Wähle eine der folgenden:

  • Pseudostratified in pulp chamber

  • Columnar at the pulp chamber

  • Cuboidal at the radicular pulp

  • Squamous at the radicular pulp

  • a single layer at the junction of the pulp and the dentin

Erklärung

Frage 10 von 13

1

Which of the following is false?

Wähle eine der folgenden:

  • Unmyelinated C fibers are pain fibers with a high threshold

  • A beta are large, myelinated, and have a low-threshold

  • A delta are small and have a high threshold.

  • A beta feel innocuous toch and mechanical sensation

  • A delta feels pain, cold, some heat

Erklärung

Frage 11 von 13

1

Which of the following is false?

Wähle eine der folgenden:

  • Irreversible pulpitis is often predicted by spontaneous pain

  • Best predictor of post-endodontic treatment plan is pre-treatment pain

  • Local anesthetics do not work as well when dental pulp is inflamed

  • The best test to determine vital versus necrotic pulp is heat followed by electric pulse.

  • Irreversible pulpitis can be asymptomatic

Erklärung

Frage 12 von 13

1

Central 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.

Wähle eine der folgenden:

  • T/T

  • T/F

  • F/T

  • F/F

Erklärung

Frage 13 von 13

Wähle eine der folgenden:

  • T/T

  • T/F

  • F/T

  • F/F
