Study Notes

Non-Surgical Periodontal Therapy

Non-surgical periodontal therapy is designed to remove bacterial plaque and local factors that favor its accumulation.

Scaling and Root Planing

Scaling is the removal of both supragingival and subgingival plaque and calculus.
Root planing is the removal of embedded calculus and rough cementum, which is the outer layer of the tooth root surface.
The primary objective of both scaling and root planing is to restore gingival health by removing etiologic factors.

Instruments Used in Scaling and Root Planing

Sickle scalers are used for removal of supragingival calculus and have a very sharp tip with a triangular cross section.
Curettes are used for subgingival calculus and have a rounded tip, either universal or adapted for specific areas of the mouth (Gracey curettes).
Universal curettes have a semi-circular cross section and a rounded tip, allowing for use in any area of the mouth.
Gracey curettes have a semi-circular cross section and are adapted for specific areas of the mouth, with one cutting edge.

Gracey Curettes

Gracie 1-2 is used for the anterior region of the mouth.
Gracie 5-6 is used for the anterior teeth and premolars.
Gracie 7-8-9-10 is used in the posterior for facial and lingual surfaces only.
Gracie 11-12 is used in the posterior for mesial and interproximal surfaces.
Gracie 13-14 is used in the posterior for distal interproximal surfaces.

Ultrasonic Scalers

Ultrasonic scalers are used for tenacious calculus and are contraindicated for patients with pacemakers, infectious diseases spread by aerosol, and at risk for respiratory disease.
There are two types of ultrasonic scalers: magneto-restrictive (Cavitron) and piezo-electric.
Magneto-restrictive ultrasonics vibrate in an elliptical pattern, while piezo-electric ultrasonics vibrate in a linear pattern.
Ultrasonic scalers have several functions, including lavage, cavitation, mechanical vibration, and acoustic turbulence.

Strokes Used in Scaling and Root Planing

Exploratory stroke: a light feeling stroke used with probes and explorers to measure pocket depth and detect calculus.
Scaling stroke: a short, strong pull stroke used for scaling.
Root planing stroke: a light to moderate poststroke used for final smoothing.
Ultrasonic stroke: a light, intermittent stroke with a tip parallel to the tooth surface.

Angulation of Curettes

When inserting a curette into the pocket, the angulation between the blade and the tooth should be zero degrees (closed angle).
When scaling and root planing, the angulation should be 45 to 90 degrees (open angle).

Prophylaxis

After scaling and root planing, a prophylaxis is provided to remove any supragingival plaque that remains on the tooth enamel.
A prophy cup and brush are commonly used for prophylaxis.
The prophy cup flexes on slight pressure to the contours of the teeth, and the brush enables better access to select occlusal grooves and interproximal areas.
