Pulpal Diagnosis
Endodontic Treatment is NOT Needed
CLINICAL CLASSIFICATION SIGNS AND SYMPTOMS DIAGNOSTIC TEST RESULTS
Normal
A pulpal condition, usually called normal, in
which the pulp responds to thermal and
electrical tests in a manner similar to that of a
corresponding control tooth.
Hypersensitive Dentin
A pulpal condition, with no apparent
histologic changes, in which the patient feels
pain when the dentin is exposed to touch
from a dental explorer, fingernail or tooth
brush and to thermal or to other stimuli.
However the pain disappears when the
stimulus is removed.
Reversible Pulpitis
Syn: hyperemia, inflamed-reversible.
A pulpal condition commonly induced by
dental caries and operative procedures, in
which the patient responds to thermal or
osmotic stimuli, but the symptoms disappear
when the etiology is eliminated.
Pain
No history of pain.
None to mild to moderate intensity
Pain is non-spontaneous
No pain with percussion
Moderate to sharp response to thermal, sweet, or
sour stimuli; response subsides when
stimulus is removed.
Etiology
Usually caries, defective restoration, restorative
procedures, mechanical pulp exposures,
tooth brush abrasion, tooth fracture,
recent prophylaxis, or subgingival scaling
and curettage.
Radiology
No radiographic evidence of pulp calcifications,
internal resorption, or periapical changes.
EPT
Response is normal and not in extremes. Is
generally in the same range as control
teeth.
Thermal Tests
Usual, normal response, for duration of the
stimulus. Reaction may be severe, but
BRIEF.
Percussion and Palpation
Negative, no response.

Pulpal Diagnosis
Endodontic Treatment IS Needed
CLINICAL CLASSIFICATION SIGNS AND SYMPTOMS DIAGNOSTIC TEST RESULTS
Irreversible Pulpitis
Irreversible pulpitis without periapical pathosis
A pulpal condition, usually caused by deep
dental caries or restorations, in which
spontaneous pain may occur or be
precipitated by thermal or other stimuli.
Radiographs show no periapical changes.
The pain last for several minutes to hours.
Irreversible pulpitis with periapical pathosis
A pulpal condition similar to above, but in
which periapical or lateral radiographic
changes are evident.
Pain
May have acute or chronic symptoms.
Sharp, exaggerated, painful response to thermal
stimulus; pain lingers after stimulus is
removed.
Pain may be spontaneous; maybe past repeated
episodes of pain, often continuous pain.
Pain with mastication.
Etiology
Deep caries and/or restorations, evidence of
previous pulp cap.
Exposed dentin (attrition, abrasion, and erosion).
Traumatic injuries.
Resorption (especially perforating).
Orthodontic forces.
EPT
Tooth may test within normal limits.
Response may be markedly different from
control, rapid/delayed onset, persistent, and
may be of severe intensity.
Thermal Test
A key factor in making a diagnosis.
May be abnormal, rapid/delayed onset, greater
intensity and longer duration.
Percussion Test
May or may not be positive.
Palpation
May or may not be positive.
Radiology
May be normal.
Radiographic evidence may reveal normal pulp,
calcifications, narrow pulp chamber,
"calcified" canals, , or condensing osteitis.
An enlarged PDL may also be present.

Pulpal Diagnosis
Endodontic Treatment IS Needed
CLINICAL CLASSIFICATION SIGNS AND SYMPTOMS DIAGNOSTIC TEST RESULTS
Necrotic Pulp
Necrotic pulp without periapical pathosis
A pulpal condition in which there may or
may not be spontaneous moderate to severe
pain or pain elicited by various stimuli.
Response to various testing modalities is
usually absent. Radiographic changes are not
evident.
Necrotic pulp with periapical pathosis
A pulpal condition similar to above, except
that in this category periapical or lateral
lesions are evident in radiographs.
Pain
May have acute or chronic symptoms.
Pain may be spontaneous; maybe past repeated
episodes of pain, often continuous, dull,
throbbing, pain.
Pain with mastication.
Etiology
Deep caries and/or restorations, evidence of
previous pulp cap.
Carious pulp exposures.
Exposed dentin (attrition, abrasion, and erosion).
Traumatic injuries.
Resorption (especially perforating).
Orthodontic forces.
EPT
No response.
May have false positives.
Thermal Test
No response.
Percussion Test
May or may not be positive.
Palpation
May or may not be positive.
Radiology
May be normal.
May be periapical lesions or lateral lesions.
An enlarged PDL may also be present.

Periapical Diagnosis
There MAY be Need for Endodontic Treatment
PULPAL DIAGNOSIS IS REQUIRED FOR DEFINITIVE DETERMINATION
CLINICAL CLASSIFICATION SIGNS AND SYMPTOMS DIAGNOSTIC TEST RESULTS
Acute Apical Periodontitis
Pain
History of pulpal pain.
Moderate to severe intensity that may be
intermittent.
Periapical pain usually requires stimulus (eg
mastication).
Pain can be sharp.
Aggravating factors are usually present.
Etiology
Irreversible pulpitis, traumatic injuries,
periodontal disease, orthodontic forces maxillary
sinusitis, pressure from periapical tumors,
restoration in hyperocclusion.
Pulp Tests
EPT and Thermal tests may be normal, or
similar to irreversible pulpitis or pulpal
necrosis.
Percussion
Moderate to severe pain.
Palpation
Moderate to severe pain.
Radiology
Usually thickening of PDL, also can have
periapical or lateral radiolucency, or normal.
Chronic Apical Periodontitis
A periapical condition characterized by none
to slight pain on mastication but may present
itself with varying degrees of apical swelling.
Radiographs reveal periapical or lateral
radiolucencies.
Pain
History of pain.
Slight intensity to no pain. Pain may be absent or
constant.
Periapical pain can be spontaneous.
Pain is dull throbbing.
Pain can occur with mastication.
Etiology
Same as for Acute apical periodontitis.
Pulp Tests
EPT and Thermal tests may be normal, or
similar to irreversible pulpitis or pulpal
necrosis.
Percussion
Moderate to none.
Palpation
Moderate to none. May be swelling.
Radiology
Periapical or lateral radiolucency.

Periapical Diagnosis
There IS a Need for Endodontic Treatment
PULPAL DIAGNOSIS IS REQUIRED FOR DEFINITIVE DETERMINATION
CLINICAL CLASSIFICATION SIGNS AND SYMPTOMS DIAGNOSTIC TEST RESULTS
Chronic Suppurative Apical Periodontitis
A periapical condition characterized by non
pain on mastication. A draining sinus tract or
other evidence of suppuration is evident.
Radiographs reveal periapical or lateral
radiolucencies.
Acute Alveolar Abscess
Syn: Acute apical abscess
An acute alveolar abscess is a severe clinical
manifestation of periapical infectious
disease, characterized by severe pain and

Irreversible pulpitis, traumatic injuries,

Pain is pulsing and throbbing.
Pain can occur with mastication.
Etiology
The result of coronal apical progression of pulpal
necrosis with resultant release of antigens into
the periapical tissues.

EPT and Thermal tests may be normal, or
similar to irreversible pulpitis or pulpal
necrosis. (Is this a lesion of endodontic origin)
