Chapter 37- Instruments and Principles for Instrumentation Flashcards
instruments used for assessment include
periodontal probe, mouth mirror, and explorer
Examples of the design name of an instrument
gracey, UNC, ODU
Three major parts of an instrument include
handle, shank, working end
the first bend in the instrument closest to the working end is called
the terminal shank or lower shank
straight/ simple shaped instrument
fewer bends and flat in nature, ideal for adaptation to tooth surfaces with easy access
angled/complex shaped instrument
contains many bends in the shank which make it ideal for adaptation to tooth surfaces that are difficult to access such as proximal surfaces of posterior teeth
the sides of the blade that converge to form the back of the instrument
lateral surface
functions of the nondominant hand
to assist the dominant hand with an auxiliary rest, or to use the mouth mirror
the palm grasp is used to grasp
air water syringe, periodontal instruments with non dominant hand when adjusting the light or when stabilizing the instrument for sharpening
muskuloskeletal disorder brought on by pressure on the median nerve in the carpal tunnel due to inappropriate work habits
carpal tunnel syndrome
for both curets and scalers, a ___ degree angulation between the face of the instrument and the tooth permits effective calculus removal
70 degrees
the pressure of the instrument applied against the tooth surface during activation
lateral pressure
strokes that are parallel to the long axis of the tooth
vertical
strokes that are parallel to the occlusal surface of the tooth being treated
horizontal
strokes that are diagonal to the long axis of the tooth being treated
oblique
