Concave Plane (flat surface) Double sided Usually flat. Concave magnifies. |
|
|
What are the uses of a mouth mirror?
|
Retraction-lip, cheek or tongue
Indirect vision-Tooth surfaces or oral structures that can't be seen directly Indirection illumination-spotlight Transillumination-shine light through anterior teeth to look for interprox. caries |
|
|
What are 4 defogging techniques for the mouth mirror?
|
-warm it up on the buccal mucosa
-have pt. breathe through nose -wipe reflecting surface with gauze soaked in mouthwash -dip in commercial defogging solution or mouthrinse made for defogging |
|
|

What are the basics of intraoral fulcrums in regards to:
Grasp Fulcrum Finger Rest Location |
-Modified pen (mirror, can spread fingers more)
-Ring finger straight, tip of finger supports weight of hand -Place fulcrum on same arch as tooth being instrumented--exceptions of probes and explorers -Position finger rest near the tooth being instrumented (exceptions-probe and explorer) |
|
|
Explain a cross arch vs opposite arch fulcrum
|
Cross arch-fulcrum on same arch as tooth being instrumented, but fulcrum is placed on one side and the instrument's on the opposite side
Opposite Arch-fulcrum on max or mn, instrument is on the opposing arch. (Probe and exploring only) |
|
|
What surface of the tooth is best to use as a fulcrum? What movement do you utilize?
|
occlusal/incisal surfaces
pivot off the fulcrum using a rocking motion. Pivoting and rolling the handle of your mirror will allow you to see all surfaces of the dentition |
|
|
A stable fulcrum and pivot motion are essential for?
|
-controlled instrumentation
-power for calculus removal -proper adaptation and angulation |
