Eugenol is widely used in dentistry as a dental analgesic and antiseptic, often incorporated into dental cements, fillings, and pastes to relieve pain and prevent infections. It is a key component in clove oil, which is applied topically to soothe toothaches and gum irritation. In the pharmaceutical industry, it serves as a precursor for synthesizing vanillin and other flavoring agents. Additionally, eugenol is utilized in perfumery and cosmetics for its pleasant, spicy aroma. It also acts as a natural preservative in food products due to its antimicrobial properties. In agriculture, it is employed as a pesticide and insect repellent.
