Correct Angulation for Calculus Removal
•-Angulation refers to the relationship between the face of an instrument
and the tooth surface
•-For calculus removal the face-to-tooth surface angulation is an angle
between 45 and 90 degrees
•-With correct angulation the cutting edge can bite into calculus and
fracture the deposit
Angulation greater than 90 degrees
one cutting edge will contact the lining of the pocket, causing tissue
damage
Angle Less than 45 Degrees
cutting edge will slide over surface of deposit causing burnished calculus
