Periodontal Dressing Flashcards
Whats periodontal dressing?
The periodontal dressing is a physical barrier that is placed in the surgical site to protect the healing tissues from the forces produced during mastication for comfort and close adaptation.
Ideal requirements for dressing
- Soft but have enough plasticity and flexibility to facilitate its
placement in operated area and to allow proper adaptation. - Set within a reasonable time
- have sufficient rigidity after setting
- have Smooth surface
- have bactericidal property
- Should not interfere with healing
- have Dimensional stability
- Should not induce reaction
- Should have acceptable taste
6 uses of periodontal dressing
1.Provide mechanical protection for the surgical wound and therefore facilitate healing .
2.Enhancement of patient comfort .
3.Prevents post operative bleeding by maintaining the initial clot in place.
4.Maintenance of debris free area
5.Supports mobile teeth
6.Providing shape and remodeling of healing tissues

2 Types Of Perio dressing?
1.ZOE dressing
2.Non ZOE
Composition Of Zoe Dressing?
Powder component :
* ZnO
* Resin - improve setting
* Tannic acid - improve setting
* Cellulose fibers - improve setting
* Zinc acetate –accelerator, better working time .
* Asbestos binder and filler
Liquid : * Eugenol, * Vegetable oil, added to dissolve Eugenol * Thymol, a weak antiseptic. * Colour additives
Non ZOE dressing contains:
Base And Accelerator
Market names of Non ZOE dressing
1.Coe Pack
2.Peri Pack
Composition of base and catalyst paste in NON ZOE Coe PACK
one paste:
Oxides of various metals –zinc oxide
* Oil-plasticity
* Gum –cohesiveness
* Lorothidol-fungicide
other paste:
* Liquid coconut fatty acids
* Resin or rosin
* Chlorothymol-bacteriostatic
: The reaction between a metallic oxide and fatty acids is the basis

Advantages of periodontal dressing
- DECREASES TIME REQUIRED FOR SUTURING
- PROVIDES RAPID HAEMOSTASIS DUE TO POLYMERIZATION IN THE PRESENCE OF MOISTURE
- ACCERLERATE EARLY PERIODONTAL HEALING
- AIDS IN PRESICE POSITIONING OF THE
FLAP/ FREE GINGIVAL GRAFT
Application of eugenol and non eugenol based material?
A. EUGENOL BASED
1.Mix maximum amount of powder into the liquid to achieve a putty mix
2. consistency is firm and thick
B. NON EUGENOL
Extrude equal lengths & quickly mix together with tongue blade until blended
Working Time?
5 minutes
How to apply dressing over site?
Apply 1 U-Strip starting from distal and placing on
the facial & lingual
Press interproximally and with a plastic instrument
adapt around the gingival surface and interproximal
areas to gain retention.
For protection & promotion of healing, the dressing
should not exceed 1-2 mm beyond the surgical site
T/F Dressing should not be in occlusal contact during closure
T
Hardness Time
30 min
Removal time
7 to 10 days
After removing perio dressing?
Polish with rubber cup
and minimally abrasive prophy paste
The wound surface is cleaned using 3% hydrogen peroxide solution OR cotton
then sprayed with water syringe and pt is sent home with OHI
