Answers
What is reversible pulpits? A clinical diagnosis based on subjective and objecting findings indicating that the
inflammation should resolve the pile and return to normal.
How do you treat reversible pulpitis? Caries removal and restoration or remineralization
What are signs/descriptors of symptomatic pulpitis Lingering thermal pain
Spontaneous pain
Referred pain
What is irreversible pulptitis A clinical diagnosis based on subjective and objective findings indicating that the
vital inflamed pulp is incapable of healing
What are signs/descriptors for asymptomatic pulpits? No clinical symptoms but inflammation produced by caries, caries excavation,
trauma, internal resorption (may also be necrotic
What is plural necrosis A clinical diagnosis indicating death of the dental pulp with the pulp using being
unresponsive to pulp testing
Root canal therapy is completed on a mandibular first Marginal integrity of definitive restoration
