Initial Guidelines




Before treating, determine a separate pulpal
and periapical diagnosis based on history
and responses to clinical tests.
Focus first on pulpal signs and symptoms, and
then periapical signs and symptoms.
Pulpal inflammation can eventually result in
periapical inflammation.
A tooth with a large periapical radiolucency must
have a necrotic pulp, if the lesion is of
endodontic origin.
Guidelines, con’t.
Post-op pain management for patients
requiring a pulpotomy or pulpectomy:
 Pre-emptive analgesia: prior to the
procedure, give the patient ibuprofen 600mg
plus acetaminophen 1000mg, orally.
 Contraindications: hypersensitivity to NSAIDs or
ASA, pregnancy, asthma, CHF, hypertension,
decreased renal or hepatic function, GI bleeding
or ulcers, or those on anticoagulant drugs.
 Injection of 0.5% marcaine following the
procedure.
PULPAL DISEASE
Classified as:

Reversible pulpitis

Irreversible pulpitis

Necrotic pulp
Pulpal Disease
Reversible
Pulpitis
Reversible Pulpitis


Condition should return to normal with
removal of the cause.
Common causes:


Caries, recent restorative procedures, faulty
restorations, trauma, exposed dentinal
tubules, periodontal scaling.
Pulpal recovery will occur if reparative
cells in the pulp are adequate.
Symptoms of Reversible Pulpitis

Thermal:


Sweets:


Hypersensitive with mild pain of <30 seconds, but
similar to control tooth
Sensitive (if caries, crack, or exposed dentin) with
mild pain of <30 seconds (similar to control tooth)
Biting Pressure:

None (unless tooth is cracked)
Clinical Findings in
Reversible Pulpitis
Visual
Check for decay, fracture lines, swelling, sinus tracts,
orientation of tooth, and hyperocclusion
Palpation
Not sensitive
Percussion
Not sensitive
Mobility
None (unless periodontal condition exists)
Perio probing
WNL (unless concomitant periodontal disease exists)
Thermal
Hypersensitive to heat or cold
EPT
Responds
Translumination Not used unless a fracture is suspected
Selective
Not necessary
Test cavity
Not necessary, tooth is vital
Radiographic
Periapical x-ray shows normal periapex
anesthesia
Diagnosis
Reversible Pulpitis


If there is a discrepancy between the
patient’s chief complaint, symptoms, and
clinical examination – obtain more
information or data interpretation.
Remember: both a preoperative pulpal
and periapical diagnosis are made before
treatment is initiated (if reversible pulpitis is only
condition, the periapical area should be normal).

If the tooth is percussion sensitive –
consider bruxism or hyperocclusion.
Treatment of Reversible Pulpitis

Remove irritant if present (caries; fracture;
exposed dentinal tubules).


If no pulp exposure: CaOH, restore, monitor
If pulp exposure:
Carious: initiate RCT
 Mechanical: >1 mm: initiate RCT
<1 mm crown planned: initiate RCT
<1 mm: direct cap or RCT


If recent operative or trauma – postpone
additional treatment and monitor.
Pulpal Disease
Irreversible
Pulpitis
Irreversible Pulpitis




Pulpal inflamation and degeneration not
expected to improve.
A physiologically older pulp has less ability to
recover due to decrease in vascularity and
reparative cells.
As inflammation spreads apically, cellular
organization begins to break down.
Localized pressure slows venous return,
resulting in buildup of toxins and lower pH that
causes widespread cellular destruction.
Symptoms of Irreversible Pulpitis

Thermal:


Sweets:


Moderately to severely sensitive (if caries,
crack, or exposed dentin)
Biting Pressure:


Hypersensitive with moderate to severe
prolonged pain (>30 seconds) as compared
to the control
Usually sensitive in later stages (periapical
symptom)
Moderate to severe spontaneous pain
Clinical Findings in

Diagnosis
Irreversible Pulpitis

Hypersensitive to hot or cold that is
prolonged.

A history of spontaneous pain.

Vital or partially vital pulp.
Treatment of Irreversible Pulpitis
Minimum immediate treatment (if not extraction)
 Pulpotomy:







Remove all decay (essential)
Large canals: passively broach 75% of tooth length
Small canals: spoon excavate orifice while removing
pulpal tissue from chamber.
Copious irrigation with sodium hypochlorite (1%).
Dry chamber with cotton pledget
Place Ca(OH)² into large and over small canals
Place dry cotton pellet in chamber, cover with cavit,
temporarily restore with Ketac-fill; completely relieve
occlusion if have acute apical peridontitis
Treatment of Irreversible Pulpitis
Ideal immediate treatment
 Pulpectomy (complete removal of pulpal tissue)


Determine the ideal working length (WL)
Fully instrument canals with master apical file






At least # 25 file for small canals (and anterior teeth)
# 35 - 40 file for larger canals
Alternate working files with #8 or 10 patency file
Copious irrigation with sodium hypochlorite (1%)
Dry chamber with cotton pledget
Place dry cotton pellet over canals, cover with cavit,
temporarily restore with Ketac-fill; completely relieve
occlusion if have acute periapical peridontitis.
Ideal Access Preparations
Irreversible Pulpitis
(more treatment considerations)



Any residual decay can result in an inadequate
seal, contamination of canal space, and interappointment flare-ups.
Inflammation can be judged by the amount of
hemorrhage from the remaining pulp stump. If
bleeding continues, re-broach or file for residual
pulpal tags with copious irrigation.
To decrease risk of instrument separation within
the canal space, do not engage the canal walls
with broach.
Irreversible Pulpitis
(additional considerations)


Do not leave teeth open between appointments –
causes contamination of the canals and difficulty
closing them later.
Incomplete tooth fractures involving the pulp will
show symptoms of irreversible pulpitis.
Periodontal probing of associated pocket will
indicate depth of fracture. If depth of pocket
(fracture) extends below the attachment level,
the prognosis is guarded to poor.
Pulpal Disease
Necrotic
Pulp
Necrotic Pulp




Results from continued degeneration of an
acutely inflamed pulp.
Involves a progressed breakdown of cellular
organization and no reparative potential.
Commonly have apical radiolucent lesion.
(always conduct proper pulp testing to rule out
a non-pulpal origin).
With multi-rooted teeth, one root may contain
partially vital pulp, whereas other roots may be
nonvital (necrotic).
Maxillary first molar with large amalgam restoration and
periapical radiolucencies around all three roots. The tooth
was unresponsive to electrical and thermal testing.

Diagnosis of Necrotic Pulp

Distinguishing features:



No response to cold.
No response to EPT.
Caveats



Decreased sensitivity to cold/ept may be from
of insulating effects of additional dentin.
Fluid in canal space conducting electrical
current can give false-positive.
Periapical radiolucency is strong but not
conclusive evidence that pulp is necrotic.

If from irreversible pulpitis:

Pulpotomy or extraction.
If from necrotic pulp:

Root canal therapy initiated or extraction.
If from hyperocclusion:
When the pulp is normal or reversibly inflamed, adjusting the
occlusion provides immediate relief. Always consider cracked tooth,
irreversible pulpitis, or necrotic pulp if discomfort persists.
If from bruxism:
A biteguard may be indicated.
Periapical Disease
Acute Apical
Abscess
Acute Apical Abscess




Acute inflammation of the periapical tissue
characterized by localized accumulation of
pus at the apex of a tooth.

Periapical Disease
Chronic Apical
Periodontitis
Chronic Apical Periodontitis




Results from prolonged inflammation that has
eroded the cortical plate making a periapical
lesion visible on the radiograph.
Caused by a necrotic pulp, the lesion contains
granulation tissue consisting of fibroblasts and
collagen (with macrophages and lymphocytes).
Must rule out central giant cell granuloma,
traumatic bone cyst, and cemental dysplasia.
Usually asymptomatic, but in acute phase may
cause a dull, throbbing pain.
Chronic apical periodontitis. Extensive tissue destruction in
the periapical region of a mandibular first molar occurred
as a result of pulpal necrosis. Lack of symptoms together
with presence of a radiographic lesion is diagnostic.
Chronic Apical Periodontitis, con’t.

Most common pitfall is assuming that the
presence of a periapical lesion automatically
indicates a necrotic pulp.
If tests indicate pulp vitality: (red flag!)

Review diagnostic information (repeat diagnostic tests)

Rule out lateral periodontal abscess, central giant cell
granuloma, traumatic bone cyst, and cemental dysplasia.


Review medical history for previous malignant lesions or
other conditions (hyperparathyroidism) that may explain
contradictory information
Do not begin treatment until this discrepancy has been
resolved
Periapical radiolucencies associated with mandibular
incisors. These teeth were vital, and a diagnosis of
cemental dysplasia was made.
Treatment of Chronic Apical
Periodontitis (necrotic pulp)



If asymptomatic, no immediate treatment
needed; schedule for root canal therapy
If in acute suppurative phase, immediate
treatment same as with acute apical abscess, i.e.,

Periapical Disease
Condensing
Osteitis
Condensing Osteitis




Increased trabecular bone in response to
persistent irritant diffusing from the root
canal into the periradicular tissue.
May be either asymptomatic (pulpal necrosis)
or associated with pain (pulpitis).
Therefore, may or may not respond to
diagnostic tests, i.e., thermal, electric,
palpation, percussion.
Root canal treatment, when indicated,
may result in complete resolution.
Inflammation followed by necrosis in the pulp of the first
molar has resulted in the diffuse radiopacity of the
periradicular tissue.
