Extraction
when the tooth can not be salvaged, extraction is necessary, end of the life of the tooth.
simple extraction
single rooted tooth, mobile tooth
surgical extraction
multi rooted teeth
why would you take a radiograph before, during and after an extraction?
Check of bone loss
check for abscess
assess difficulty
be sure there are no root fragments
Docuentation
AVDC
American Veterinary Dental College
AVDC stance on extractions
LVT can NOT do anything that alters the dental arcade. DVM only.
Extractions - force technique
breaks bone and tooth root, can bend elevator, traumatic and not recommended
Extractions - Periodontal Ligament Stretch
stretch and tear the ligament fibers, use rotation and rocking back and forth motion to ease from socket,
Root Removal
Use root pick
take radiographs
fee apical delta
Extraction technique for single rooted teeth
extracted using elevators working around the tooth to detach the periodontal ligament
Extraction technique - multi rooted teeth
extracted by splitting the teeth at the furcation using a high speed burr
vertical and horizontal extration
vertical - elevator parallel to root, slow and steady pressure on each side 5-15 seconds
Horizontal
perpendicular to the crown and tooth root, careful to to luxate the tooth.
Simple extractions complications
old dog w. stubborn roots
MGF
Mucosal Gum Flap
performed before multi rooted tooth extraction, 11 blade used to incise, gingiva stripped from bone. Incision made on mesial-buccal, distal buccal line of adjacent teeth.
pulverization
part of the root is drilled with a high speed burr, not recommended, in some cases better to leave the root intact.
to protect pulp chamber from thermal damage during ultrasonic scaling you should
use constant irrigation, do not spend more than 7 seconds on each tooth
when measuring the depth of gingival sulcus, the probe should be _________ to the long axis of the tooth
parallel
Disclosing Solution
used to detect missed plaque/calculus
_____ prophy paste can be used for supra and subgingival cleaning
coarse
____ water is required to cool ultrasonic scalers
less
Prophylaxis is defined as. . .
the prevention and protective treatment for periodontal disease
Why isn't flouride treatment rinsed off the teeth?
It needs to absorb into the tooth and sit for 3-5 minutes
Fluoride acts to accomplish. .
Desensitize teeth, strengthen enamel, slow reattachment of plaque
The deepest part of the root is the. ..
apex
PerioBUD
Periodontal Bacterial Ultrasonic Debridement
UPL
Ultrasonic Periodontal Lavage
Root Planing
definitive removal of plaque and calculus and cementum to create a clean surface for the gingiva to reattach. * Done when there is actually a pocket *
periodontal debriedment treats. . .
gingival and periodontal inflammation
2 root planing techniques
open = greater than 5 mm
closed = 4-5 mm
Why is ultrasonic scaling better than hand scaling for root planing?
removes plaque/calculus
flushes pocket
water lavage
more efficient
less distention of gingiva
removes less cementum
What tools are used for root planing?
curette, with overlapping crosshatch strokes

ultrasonic *preferred *
HESKA PerioCeutic Gel
Doxycylelne. Injected locally into pocket. Treats Gram + and - bacteria, decreases pocket depth

it is packed into pocket and hardens, fights infection, inhibits tissue destruction and prevents debris from filling the pocket. Lasts up to 2 months.
Periodontal SX main objective
contribute to the preservation of the peridontium by removing plaque and controlling accumulation in the future
Gingivectomy
(Gingivioplasty) various flap techniques that access flaps for open curettage and osseous surgery
Periodontal SX Followup
recheck in 2-4 weeks, Education and next step, treatment plan (cleanings 6mo to 1year), Home care, appropriate chew toys, cholorhex rinse.
Instruments for Surgical Extractions
Scalpel handle and blade (11 or 15), small needle holders, thumb forceps, absorbable suture, elevators, root tip pick, cross burr
Single Rooted Teeth - Dogs
Incisors, Canines, First Premolar, 3rd Molar of mandible
Triple Rooted Teeth - Dogs
4th Premolar of maxilla, 1st and 2nd Molar of maxilla
Carnasial Teeth
Dogs: upper 4th premolar, lower 1st molar
Ultrasonic scaler types and speeds
Magnetostrictive: 18,000-29,000 cycles per second

Piezoelectric: 40,000 cycles per seconds (least traumatic)

Sonic: 18,000 cycles per second
Dental Radiography Purpose
Ascertain condition of teeth and gingival sulcus, identify cavities and resorptive lesions, Identify retatined roots, evaluate intraoral neoplasia, identify number of teeth in mouth, identify periapical abscess.
