T/F In irreversible pulpitis the pain will go away as soon as the stimulus is removed

F. The pain lingers after the stimulus is removed


What percentage of maxillary first molars have 4 canals? Maxillary Second Molar?

Maxillary First Molar: 94% have four and 6% have three.
Maxillary Second Molar: 1=10% 2 =25% 3=60% 4= can be found but are in close proximity


Maxillary first premolar canal percentages? Maxillary second premolar?

Maxillary First premolar: 1=9% 2=85% 3=6%
Maxillary Second premolar: 1=75% 2=24% 3=1%


Mandibular Central Incisor canal percentages? Mandibular Lateral Incisor?

Mandibular Central Incisor: 1=70% 2=30%
Mandibular Lateral Incisor: 1=57% 2=43%


Are mandibular incisors more likely to have 1 or 2 canals?

1 is more likely


Clinical diagnosis based on subjective and objective findings indicating that inflammation should resolve and the pulp return to normal is _________.

Reversible Pulpitis


Maxillary 1st bicuspids commonly have how many roots and how many canals?

Normally two roots and two canals


Symptomatic vs Asymptomatic irreversible pulpitis

A clinical diagnosis based on subjective and objective findings indicating that the vital inflamed pulp is
incapable of healing.
Additional descriptors…..
– Symptomatic – Lingering thermal pain, spontaneous pain, referred pain
– Asymptomatic – no clinical symptoms but inflammation produced by caries, caries excavation, trauma


T/F Reversible pulpitis can occur with no stimulation at any time

– Pain is NOT spontaneous or unprovoked


T/F Irreversible pulpitis, pain will endure when stimulus is removed



In Irreversible pulpitis, if you remove the stimulus pain will endure after the stimulus is removed

– Know about them
– True, the pain lingers
– Pulp is vital severely inflamed
– Symptoms usually intense acute could be chronic
– Pain may be poorly localized
– Pain is spontaneous
– Pain to hot and cold (cold may make it feel better at later stages)
– Pain lingers after stimulus is removed
– May or may not be sore to percussion
– Normal PDL or may be thickened


In reversible, which statement is true?

– Know about it
– Pulp is vital with some minor degree of inflammation
– Mild symptoms or no symptoms
– Mostly sensitive to cold
– Pain rapidly subsides when stimulus is removed
– No carious exposure
– No sensitivity to percussion
– Pain is not spontaneous or unprovoked


Symptomatic Apical Periodontitis

Inflammation usually of the apical periodontium, producing clinical symptoms including a painful response to biting and/or percussion or palpation. It might or might not be associated with an apical radiolucent area


Noramal Apical Tissues

Teeth with normal periradicular tissues that are not sensitive to percussion or palpation testing. The lamina
dura surround the root is intact, and the periodontal ligament space is uniform


Pulp Necrosis

Clinical diagnostic category indicating death of the dental pulp. The pulp is usually nonresponsive to pulp testing


Which is not an example of objective findings in SOAP?

i. Objective:
– Diagnose – any IN OFFICE EXAM
– Radiographs
– Pulpal space
– Tooth morphology and position
– “if you cant put a RD on it, don't do the root canal.”
ii. Not objective
– Subjective, assessment, plan
– Pain information


T/F Periapical or periradicular pathosis is a consequence of pulpal necrosis

– Can range from slight inflammation to extensive destruction of tissue


Chronic Apical Abscess

An inflammatory reaction to pulpal infection and necrosis characterized by gradual onset, little or no discomfort, and the intermittent discharge of pus through an associated sinus tract
