What is NOT a component of the non-eugenol periodontal pack (Coe-Pak)?

In the context of non-eugenol periodontal packs like Coe-Pak, each component serves a specific function that contributes to the efficacy and stability of the material when applied after periodontal surgery.

Zinc oxide is a key ingredient in these types of packs, providing structural integrity and enhancing the healing environment for the surgical site. Chlorothymol serves as a bacteriostatic agent, which helps to inhibit the growth of bacteria and reduces the risk of infection. Gum in the formulation acts as a binder, giving the pack its desired consistency and texture, making it easier to mold and place securely over the surgical area.

Petroleum jelly, however, is not included in the formulation of non-eugenol packs like Coe-Pak. Instead, materials used in the packs focus on promoting healing and comfort without the potential adverse effects that petroleum-based products might contribute. Thus, recognizing the role of each component highlights why petroleum jelly does not belong in the composition of a non-eugenol periodontal pack.
