Iodoform is an organoiodine compound with the formula CHI3 and a tetrahedral molecular geometry. It is a relatively water-insoluble yellow solid that is chemically reactive in free-radical reactions . Due to its antimicrobial properties following topical administration, minimal levels of iodoform may be found in disinfectants and it is more primarily used for veterinary purposes. Iodoform has also been found in dental paste and root canal filling materials in combination with other intracanal medications due to its radiopacity . Since the beginning of the 20th century, iodoform has been commonly used as a healing and antiseptic dressing or powder for wounds and sores, however such clinical use to this date is limited. Iodoform is soluble in fatty acids and decomposes releasing iodine in nascent state (96,7% of iodine) when in contact with secretions or endodontic infections .

While the mechanism of action of iodoform remains unclear, it is proposed that iodoform releases iodine, which denatures bacterial proteins by oxidation of the free iodine . Iodoform may also play a role in chemical debridement for effective necrotic wound healing and tissue damage repair via collagen fibrinolysis; upon treatment in necrotic tissue, iodoform reduced the size of the macromolecules containing collagen I in wound surface proteins . In human gingival fibroblasts in vitro, high concentrations of iodoform was shown to decrease the viability of macrophages and epithelial cells and reduced the secretion of P. gingivalis-induced TNFα . P. gingivalis is an anaerobic bacteria present in anaerobic oral niches including periapical sites and periodontal pockets .
