CALCIUM HYDROXIDE AS INTRACANAL MEDICAMENT PDF

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%.

The first part of this review details the characteristics of Ca OH 2 and summarizes calcum results of in vitro studies related to its antimicrobial effect. Review of ultrasonic irrigation in endodontics: Currently, Ca OH 2 is considered the first choice of root canal dressing materials. The effects of surgical exposures of dental pulps in germ-free and inrracanal laboratory rats. Efficacy of various intracanal medicaments against Enterococcus faecalis in primary teeth: An in vitro study demonstrated that Ca OH 2 hydrolyzed the highly toxic lipid A molecule that is responsible for intracabal damaging effects of endotoxin.

To be effective against the bacteria located inside the dentinal tubules, hydroxyl ions from Ca OH 2 must diffuse through the dentin and reach sufficient levels to be lethal.

Antimicrobial Activity of Calcium Hydroxide in Endodontics: A Review

Where bone loss has occurred, the use of a root canal medicament between treatment sessions is recommended by some, 41 because the success of treatment in cases with periapical pathosis is directly related to the elimination of bacteria from the root canal system. Studies reporting antimicrobial effect of Ca OH 2 using infected dentin models with human teeth. Although some studies have supported the antimicrobial effect of Ca OH 2others have questioned its efficacy.
