This document discusses the prevention of periodontal diseases. It states that prevention is better than cure and cheaper than treatment. It defines periodontal diseases as those affecting the tissues surrounding and supporting the teeth. The main causes are bacterial plaque, host response factors, and reduced tissue repair capacity. Prevention methods include mechanical plaque removal using various toothbrushing techniques, flossing, and oral irrigation. Chemical controls include antimicrobial mouthwashes containing chlorhexidine or essential oils. Professional treatment involves nonsurgical scaling and root planing to remove deposits, as well as antimicrobial therapy. The goal of polishing after treatment is to remove soft deposits with minimal trauma.

7. ** Tooth Brushing Methods:Bass Method:
•Intrasulcular method (Professional method).
•Efficient for removing dental plaque from gingival third and
from shallow gingival sulcus.
•Place the bristles at the gingival margin with angle of 45 degree
to the long axis of the teeth and the bristles pointed to the
crevice.
•Exert gentle vibratory pressure using short back-and-forth
motions without dislodging the bristles tips (horizontal
direction).
•Perform about 10-20 strokes in each position.
•Use a soft brush in this method.

10. Modified Stillman Method:•A soft or medium brush can be used with this method.
• Recommended for patients with gingival recession to
prevent abrasive tissue destruction.
•The sides of the bristles are placed against the gingiva
and teeth with a 45 degrees angle to the long axis
of the teeth.
•Pressure is applied laterally against the gingival
margin to produce blanching.
•Brush is activated by short back-and-forth strokes in
coronal direction.
12. Charters Method
•
A soft or medium brush can be used.
• Recommended for temporary cleaning in
areas of healing after periodontal surgery.
• The bristles pointed toward the crown at a 45
degree angle to the long axis of the teeth.
• The bristle tips not move across the gingiva.
•The brush is activated with short back-and
forth strokes in coronal direction.

Useful for: Children, hand-capped, and patients
with orthodontics treatment.

16. II- Interproximal Cleaning Aids:• 1- Dental Floss:
Effective for flat or convex proximal tooth surfaces with full
embrasures.
• Waxed, unwaxed or tufted types.
• Tufted and waxed are indicated for rough
restoration and tight contact
• Cut about 12-15cm and anchored around one
finger of each hand.
• Gentle placing at the base of gingival sulcus then
moved in an up-and down along the tooth surface
,right and left.
17. 2- Interdental Brushs:
•Small cone-shaped or tapered brushes.
•Used in large open embrasures.
•Inserted interdentally and moved back and forth in faciolingual direction.
3- Tooth Picks:•Made from soft-wood and is triangular in shape.
•Used in open contact.
•Tooth pick moved in-and-out or up-and down direction.
•Tooth pick can be placed in special plastic handles to reach
areas with limited access.
18. III- Oral Irrigation:•With water and antiseptic mouth rinses.
•Supra or sub-gingival irrigation.
•Hand or mechanized irrigation.
