Although in medicine it is used as synonym of Eidronic Acid, Etidronate is a salt of etidronic acid.
The Etidronic acid is a phosphonate derived from phosphorus, used as a corrosion inhibitor.
Applications and uses:
- Fertilizers
- Pesticides
- Degreasers
- Detergents
- Antibacterial

Prior to obturation, the intracanal medicament should be removed. Medicament residues can reduce root canal permeability by promoting the formation of calcium carbonate particles and interfering with sealing ability of root canal sealers (1).
The aim of this study was to compare the efficiency of irrigation protocols (EDTA, citric acid, and etidronate) in Ca(OH)2 removal. Inter-group comparison showed that in the coronal-third, etidronate (Group-III) showed highest cleanliness scores, followed by EDTA (2).
In this root canal study, ethidronic acid showed less removal efficacy than SmearClear and MTAd (3).

Hip fracture is among the most common causes of acute immobilization in elderly patients leading to increased bone resorption, and elderly patients with hip fracture are at high risk for a subsequent hip fracture. Etidronate therapy inhibits bone resorption and improves calcium balance, and such therapy may prevent bone loss and reduce the risk of subsequent hip fracture (4).
