Percussion as a diagnostic tool primarily to determine:
chronic periradicular inflammation
best way to diagnose pain of odontogenic origin
step by step sequenced exam and testing approach
Pulp impt for forming tooth – is the tooth a dead tooth after you’ve done root canal treatment ?
Tooth is non-vital because it lost its vital pulp, but not dead.
Endodontic file - what does 10 mean?
(10 means its a tenth of a mm at the tip)
Endo Triad
Access Opening, Clean and Shape, Seal
The most common cause of pulp damage is
severe decay or a fracture that exposes the pulp to bacteria that may cause infection.
- Apexification
- often endo go into and treat teeth where pulp isn’t even fully formed – root wall is so thin and immature that structurally when that person is an adult, tooth will just fracture
- Hexification
if there’s enough root wall, we will stimulate body to create endpoint in root canal so we can fill resistance form against it
- We do manage to save this open apices of teeth
- Root canal obturation
purpose is to seal all portals of communication between the root canal complex and the surrounding attachment apparatus
trioxide aggregate (MTA) –
medical grade concrete
A blow to a child’s permanent tooth that is not fully formed can cause injury ____
- and, ultimately the root may
to the pulp

cease development
orthodontic extrusion
lifting of a submerged root above the gum level for restoring, thus avoiding surgical crown lengthening.
avulsed tooth
complete separation of a tooth from its alveolus by traumatic injury

Replantation and splinting of the tooth must precede any type of treatment.
when are intentional re-implantations possible?
as long as the periodontal ligaments are intact
Performs Hemisection:
the surgical separation of a mandibular molar tooth, through the furcation in such a way that a root and / or the crown portion may be removed.
Performs Endodontic Retreatment:
The redoing of previous treatment that is unsuccessful; retrieval of canal obstructions and complete or partial disassembly of restorative materials are frequently required.
Guided Tissue Regeneration
attempts to regenerate lost periodontal structures using barrier membrane techniques
spread of disease into bone
3 C's
color, contour, & consistency
hard, rock hard, fluctuant means soft.

an early state.

initial swelling that is rock hard
always fluid filled
Blushed tooth
pulp is bleeding
5 major irritants to health of pulp
1) heat
2) mechanical
3) dessication
4) chemicals
5) caries
electric pulp test
small electric current to test brain's recognition to tooth
thermal tests
those with hot and cold

normal thermal test can provoke tooth with piece of ice
selective anesthesia
upper then lower blocks

- help ID which quadrant pain is coming from
test teeth - radiographs in conjuction with testing

true or false
reacted then return to normal
3 hallmarks for irreversible pulpal disease that requires root canal therapy
Lingering duration
Point of references ...
challenge away or contralateral tooth to what we're looking at

challenge opposing tooth or arch

challenge the quadrant
A-delta Fibers
Located in Pulp-Dentin interface
Large Diameter
A-delta Fibers
Cold / Heat Thermoreceptor for Pain
C fibers
C- Fibers:
Located Centrally in the Pulp
Small Diameter
C fibers
Heat Thermoreceptor for Pain

Dull / Gnawing
Prolonged / Spontaneous
Class I tooth mobility
wiggle within/up to a millimeter
Class II tooth mobility
wiggle a millimeter
Class III tooth mobility
wiggle a millimeter and depression in socket
Test cavity: No response
pulpal necrosis
Test cavity: Slight response
Degenerating pulp
Acute response
Vital pulp
Test cavity: Necrotic

what to do?
endodontic access
Tooth slooth: No pain
shallow fracture
Tooth slooth looks for fracture - will provoke which pain fibers?
A delta fiber pain
Tooth slooth: sharp pain
- cuspal fracture

- vertical fracture

- horizontal fracture
How to determine if there's damage down to root?
Flex with tooth slooth & probe around with perio probe

- shows bone loss adjacent to fracture then it's down to root
