A study was done to quantify the release of calcium ions from calcium hydroxide containing root canal sealers and their pH at various time intervals and the antimicrobial action. pH was measured using the pHmeter and the calcium amount using the atomic absorption spectrometer. Six strains of microorganisms were used to evaluate the antimicrobial action of the sealers using Agar diffusion test. Seal apex showed the maximum release of calcium ion and pH level at 30 days but with no antibacterial effect.
