Terms
undefined, object
copy deck
- 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
- calculus
- 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
