Opposite Arch Fulcrum - ✔✔-Intraoral fulcrum which finger rest is on opposite arch form
|| || || || || || || || || || || || || ||
treatment area ||
-Used to improve access to deep pockets and to facilitate parallelism to proximal root surfaces
|| || || || || || || || || || || || || ||
Cross-Arch Fulcrum - ✔✔-Intraoral fulcrum where finger rest is established on opposite side of
|| || || || || || || || || || || || || ||
arch from treatment area
|| || ||
-Rest ring finger on a tooth on opposite side of arch
|| || || || || || || || || ||
Basic Extraoral Fulcrum - ✔✔Extra-oral fulcrum which dominant hand rests against patients chin
|| || || || || || || || || || || ||
or cheek
|| ||
Finger on Finger Fulcrum - ✔✔-Intraoral fulcrum in which finger of non-dominant hand serves
|| || || || || || || || || || || || || ||
as resting point for dominant hand
|| || || || ||
-Improves parallelism of lower shank to tooth surface || || || || || || ||
-Nondominant index finger provides stable rest for improved access to deep perio pockets || || || || || || || || || || || ||
Finger Assist Fulcrum - ✔✔Finger on non-dominant hand is used to concentrate lateral pressure
|| || || || || || || || || || || || || ||
against tooth to help control instrument stroke
|| || || || || ||
Index finger on non-dominant hand against shank of perio instrument
|| || || || || || || || ||
Sequence for Instrumentation on Multirooted teeth - ✔✔1. Debride root trunk using distal curette
|| || || || || || || || || || || || || ||
then mesial ||
2. Treat each root as separate tooth. Use distal on distal portion of each root.
|| || || || || || || || || || || || || ||
3. Use mesial curette on each mesial root
|| || || || || || ||
4.Treat roof of furcation and concavity coronal to furcation entrance with mesial curette
|| || || || || || || || || || || ||

Powered Instrumentation Devices - ✔✔Rapidly vibrating irrigate working-end to dislodge
|| || || || || || || || || ||
calculus from tooth, disrupt biofilm, flush out bacteria from perio pocket
|| || || || || || || || || ||
Sonic - ✔✔Converts air pressure into high frequency sound waves that produce vibrations of
|| || || || || || || || || || || || || ||
working end; operate low frequency of 3000-8000 cycles per second and driven by compressed
|| || || || || || || || || || || || || ||
air from dental unit
|| || ||
Ultrasonic - ✔✔Converts electrical energy into high frequency sound waves that produce rapid
|| || || || || || || || || || || || ||
vibrations; operates at 18,000-50,000 cycles per second || || || || || ||
Piezoelectric - ✔✔Electrical energy to activate crystals within handpiece to produce vibrations
|| || || || || || || || || || ||
Magnetostrictive - ✔✔Transfer energy to metal stacks or a ferrous rod to produce vibrations of || || || || || || || || || || || || || || ||
powered working-end ||
Effectiveness of Powered Ultrasonic Instrumentation - ✔✔Effective removal of calculus deposits
|| || || || || || || || || || ||
and plaque biofilms
|| ||
Pocket penetration ||
Access to furcation areas || || ||
Irrigation
Shorter Instrumentation time || ||
Facilitation of difficult instrumentation tasks || || || ||
Ultrasonic: Mechanical, water irrigation, and cavitation - ✔✔Several mechanisms of action
|| || || || || || || || || ||
