|
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
|
|
|
palpation
|
spread of disease into bone
|
|
|
3 C's
|
color, contour, & consistency
|
|
|
Induated
|
hard, rock hard, fluctuant means soft.
an early state. initial swelling that is rock hard |
|
|
Fluctuant
|
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 |
true
|
|
|
WNL
|
reacted then return to normal
|
|
|
3 hallmarks for irreversible pulpal disease that requires root canal therapy
|
Intensity
Spontaneity Lingering duration |
|
|
Point of references ...
|
challenge away or contralateral tooth to what we're looking at
challenge opposing tooth or arch challenge the quadrant |

wiggle within/up to a millimeter
|
|
|
Class II tooth mobility
|
wiggle a millimeter
|
|

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 |
