goal of oral prophylaxis
prevention of periodontal disease
periodontal disease
any pathologic alteration of the perodontium gingivitis, periodontisits or a combination of pathologic factors. this terminology does not refer to periodontitis only.
Primary etiology of periodontal disease
bacterial plaque/biofilm
mineralized plaque
what color is supramarginal calculus?
light bc it is plaque and saliva
what color is submarginal calculus?
serumal (dark) bc of blood
significance of calculus
calculus is porous and is covered with plaque
oral prophalaxis
a preventive procedure where plaque/biofilm, calculs and stain are removed from the tooth surface
objectie of oral prophy
to facilitate effective plaque control

to provide a biologically acceptable root surface

to reduce gingival inflammation, edema, and bleeding
oral prophylaxis sequence
-take plaque index and record

-provide plaque control inst.

-check for deposits w/explorer and compressed air

-scale and disrupt plaque for each too

-rubber cup polish

-flouride treatment
what is ultrasonic scaler used for?
heavy deposit, stain, plaque/biofilm removal
What is sonic scaler used for?
medium to light deposit, stain, plaque/biofilm removal
What is scalers and curets used for?
medium to light deposit, stain, plaque/biofilm removal
What is rubber cup polish used for?
stain and plaque removal
indications to use the ultrasonin scaler
heavy depostit removal
overhang removal
heavy stain removal
dental cement removal
treating pericornitis (NUG)
plaque buildup
Contraindications with the ultrasonic scaler
using point on tooth (NO!)
hot tip
pts w/pacemaker
pts with infectious disease
pts w/heart murmurs
pts w/dental implants
how does ultrasonic and sonic scalers work?
move debri w/ water and vibration against tooth
w/ the ultrasonic the pt feels little discomfort as long as ....
tip is not hot
water supply adequate
tip is in motion
when are powered scalers more effective than manual?
when instrumenting class II and class III furcations
disadvantage of ultrasonic and sonic scalers
contaminated aerosols
blue, pink,green insert for ultrasonic scaler
strait tip is blue

swivel tip is pink

blue/pink are univerisal in mouth and removes hvy calculus and stain

green is slim tip used for lighter, deeper calculs
should you use the point of the ultrasonic scaler?
NO only the tip
when is ultrasonic highly recommended
for NUG, periconitis, or acute gingivitis
Why should surfaces be checked w/an explorer even when using ultrasonic?
w/ultrasonic you lose tactile sensitivity
ultrasonic vibrations vs. sonic vibrations
ultrasonic is 25,000 to 35,000 cycles per sec

sonic is 2,000 to 6,500 cycles per sec

sonic has less power and does not move calculus as rapidly
advantage of sonic scaler
smaller tip size
tip is curet shaped
easy to set up
fits in high speed hand piece
less expensive
what should be worn when using the ultrasonic/sonic scalers?
face shield
surgical cap
eye wear
over gowns

bc contaminated aerosols
how to set up sonic scaler
attach the scaler to the hi speed handpiece tubing. slide back the connector ring and insert scaler into coupling. attach tip to scaler, step on reheostat and turn tip clockwise
After using ultrasonic, when surface appears calculus free, what should be done?
root plane w/curet
what is curet used for?
supramarginally and submarginally to remove hard and soft depostis, debridgement, and planing of cemental and enamel surface of the tooth
description of curet
lightweight round handle

shank is angled,straight, and flexible

spoon shape w/curved cutting edge

later sufaces, back, and tip are round and cross section of tip is a half circle

only lower one third of tip of cutting edge is adapted to tooth
What is barnhard/universal curet used for?
supramarginally or submarginally on anterior and posterior teeth to remove deposits, plaque, and stain wo trauma
why is barnhard called a universal curet?
bc used in all areas of mouth
Barnhart working ends
mirror images. one end is used for lingual surface and the other is used for buccal surfaces
how is fulcrum changed on distal when working w/universal curet?
fulcrum should be lowered for distal
where does stroke for curet begin?
distal line angle and goes into distal interproximal, then using the other side of blade at distal line angle and into mesial interporimal surface
what does flexing shank of curet allow for?
good tactile sensitivity and the rounded back and toe allow for use submarginally wo trauma to soft tissue
