Flashcards in Test 2 Deck (34):
Protect soft and hard tissue not involved in procedure.
Prevents ingestion or aspiration of debris, medication or biomaterials.
Decrease time for dental procedures.
Increases success rate or dental procedures.
What is the biggest worry during a dental procedure which would cause us to isolate?
Aspiration of debris, medication or biomaterials.
What are the three levels of isolation?
Low saliva technique.
No saliva technique.
Describe clear field isolation
Free of obvious debris.
Free of blood and most saliva.
Therapeutic procedures: desentsitizing, surgical, scaling and rootplaning, gingival curettage, extraction.
Describe low saliva isolation
Cotton rolls, fingers, dry angles.
Desensiticing, some surgical, root planing, curettage, preventive procedures - fluoride application -trays.
Describe no saliva isolation
Rubber dam or garmers.
Endodontics, prosthodontics, pit and fissue sealants.
What does desiccated mean?
How is fluorosis treated?
What happens when there is mineralizing but no demineralization?
What is Sjgrens syndrome?
Severe salivary flow reduction
How long does it take till teeth fully mineralize?
What effect does fluoride have on smooth surface demineralization or decay?
It improves host resistance.
When would you use fluoride?
Smooth surface demineralization.
Adults with recession.
Compromised salivary flow.
Teeth supporting overdenture.
Poor oral health due to physical/mental disability.
What three factors contribute to caries?
Susceptible tooth surface.
Dietary fermentable carbs, especially sucrose.
Describe demineralization compared to hypomineralization.
Often under plaque.
Usually around gingival margins or interproximals.
May be seen around existing restorations.
Describe hypomineralization to demineralization.
Febrile. (caused by fever)
Often seen on cusp tips (snow cap fluorosis).
Also seen on facials.
Can topical fluoride penetrate thin plaque biofilms?
Yes, but ideally we leave client plaque free.
How do you apply fluoride?
Apply 10 ml in cup.
Vaseline on clients lips.
Look for lesions
Slather fluoride on teeth.
When would you use fluoride varnish?
Full mouth caries prevention or localized desensitizing.
What does air polish deliver by a stream of air and water.
What does air polishing do?
Removes extrinsic stain, plaque and debris from clinical crowns.
Can you use air polishing on orthodontic patients and sealant bonding prep?
What are indications for use of air polishing
Therapeutic and cosmetic.
Removal of plaque, soft debris, extrinsic stain.
Prophylaxis of orthodontic clients.
How much faster is stain removed by air polishing vs curette?
3.15 times faster.
Is air polishing detrimental to either composite resin or zinc phosphate cement?
No, it is not detrimental
What is the most effective method of plaque removal for orthodontic clients, without causing breakage of elastics or wires or loss of zinc phosphate or composite material.
What is the most time effective method of plaque removal?
Which is more abrasive curette or air polishing?
How is abrasivity of air polishing determined?
What is the average root structure removed from hand curette vs air polisher?
Hand curette: 27.09 microns.
Air polisher: 10.68 microns.
How long are implants treated with air abrasive polishing system?
During air polishing, where should nozzle be placed?
Tip 3-4mm away from the tooth.
During air polishing, how should nozzle be angulated?
Anterior: 60 degrees
Posterior: 80 degrees
Occlusal: 90 degrees.
