Calcium hydroxide is a multipurpose agent, and there have been an increasing Some of its indications include inter-appointment intracanal medicaments. role of calcium hydroxide in the field of endodontics, focusing on its droxide can be used effectively as intracanal medicament, root canal. Calcium hydroxide (Ca(OH)2) has been widely used as an intracanal medicament for endodontic retreatment, but very few studies used both Ca(OH)2 and 1%.

However, PCR results showed a positive result on most of the experimental groups. IKI disinfected dentin effectively, but bacteria remained viable in the dentin after extended periods of Ca OH 2 treatment.

Farhad A, Mohammadi Z. Journal List Chonnam Med J v. Imlay JA, Linn S.

It dissociates into calcium and hydroxyl ions on contact with an aqueous solution, and the main actions of Ca OH 2 are attributed to the effect of these ions on vital tissues, such as inducing hard tissue deposition and being antibacterial. Rev Fac Odontol Bauru. Support Center Support Center. The purpose of this article is to review the antimicrobial effect of Ca OH 2 as an intracanal medicament in root canal treatment. Both laboratory and in vivo studies have shown that buffering by dentine, particularly in the subsurface layers of the hydrroxide canal walls, might be the main factor behind the reduced antibacterial effect of Ca OH 2.
