Tannic acid is added in the dressing material as a hemostatic agent, but its systemic absorption is associated with liver disease 37. After the completion of the reaction, some eugenol remains un-reacted, which may induce a burning sensation or allergic reaction in the mucosa. The setting reaction between zinc oxide and eugenol results in the formation of zinc eugenolate. Rosin: Filler, increases strength and speeds the reaction.Įugenol: Anesthetic, antiseptic, and obtundent. The specific functions of its components are, The liquid contains eugenol, peanut oil, rosin. The powder consists of zinc oxide, tannic acid, rosin, kaolin, zinc stearate, cellulose fibers and asbestos. The powder-liquid dressing is prepared by mixing the powder and liquid. These dressings are available in powder-liquid or paste forms. The components of zinc oxide eugenol dressing consist of powder and liquid.

There are primarily three types of periodontal dressings: zinc oxide eugenol dressings, zinc oxide non-eugenol dressings, and dressings containing neither zinc oxide nor eugenol. Placement of periodontal dressing Types of periodontal dressings The composition of the periodontal pack has changed over a period of time and potential tissue irritants have been eliminated from its composition. Later on, light-cured dressings were introduced which are especially useful in the anterior tooth region and particularly following mucogingival surgery because their esthetic appearance is acceptable and these can be applied over the grafted soft tissue without its dislocation. These led to the introduction of non-eugenol dressings in the late 1950’s 36. These include, a persistent taste of eugenol, the rough surface of the set material, and the tendency to cause tissue necrosis. Periodontal dressings containing eugenol had some inherent problems associated with them. It was made up of zinc oxide and eugenol, alcohol, pine oil, and asbestos fibers. A W Ward introduced the first commercially available periodontal dressing material called “Wonderpak”. History of periodontal dressing dates back to 1918 when Zentler 35 reported the use of a periodontal dressing in the form of iodoform gauze.
