DHY 150 FPI 14 and 15 test
questions and answers
Supragingival calculus deposits
deposits located coronal to the gingival margin, usually on the crowns on
the teeth
periodontium
the tissues that surround and support a tooth in the dental arch. include
the gingiva, periodontal ligament, cementum, and the alveolar bone.
angulation
the relationship between the face of a calculus removal instrument and
the tooth surface to which it is applied
pinch pressure
the pressure exerted by the fingers in the modified grasp when holding
the instrument handle
stabilization
the act of preparing for an instrumentation stroke by locking the joints of
the ring finger and pressing fingertip against a tooth surface to provide
control for the instrumentation stroke
lateral pressure
the act of applying equal pressure with the index finger and thumb inward
against the instrument handle to press the tip-third of the cutting edge
against the tooth surface prior to and throughout and instrumentation
stroke
burnished calculus deposit
a calculus deposit that has had the outermost layer removed
sickle scaler
, a periodontal instrument used to remove calculus deposits from the
crowns of the teeth
anterior sickle scaler
designed for use on anterior treatment sextants
posterior sickle scaler
designed for sued on posterior sextants but they also may be used on
anterior teeth
outer cutting edge
cutting edge that is farther from the instrument handle
inner cutting edge
cutting edge that is closer to the instrument handle
correct technique
involves positioning the cutting edge against the proximal surface with
the working-end beneath the pointed projection of the papillary gingiva
Light Supragingival Calculus Deposits
commonly on the lingual surface of the mandibular anterior teeth
Thin Layer of Supragingival Calculus Deposits
common site is facial surface of the maxillary first molar
heavy supragingival calculus deposits
