It has been shown that in an aerobic atmosphere MTA can generate reactive oxygen species which, as reported above, have an antimicrobial activity similar to that obtained with
calcium hydroxide. However, under anaerobic conditions, a decrease in the generation of radicals was observed [51].
Comparing with mixtures made with
calcium hydroxide was saved some relation, although the same concentration is much greater the weight of calcium carbonate than the lime.
Dentin cylinders or bars milled from bovine or human teeth respectively, were treated with
calcium hydroxide and subjected to compressive or shear forces.
After the temporary restoration and
calcium hydroxide dressing were removed, the canal was chemically cleaned again with sequential passive ultrasonic irrigation using 2.5% NaOCl, followed by 10 mL 17% EDTA for 1 min, 0.9% normal saline, and 2% chlorhexidine solution.
Comparative evaluation of mixture of
calcium hydroxide and chlorehexidine with triple antibiotic paste and combination of
calcium hydroxide, chlorhexidine and lycopene on incidence of interappointment flare-up: An in vivo study.
Calcium hydroxide has been used famously in the past for induction of apical barrier, having success rates ranging from 79%-96%.6 However, being a long history of use in apical closure procedures, there are many drawbacks associated with the use of
calcium hydroxide for apexification procedure.

calcium hydroxide. J Endod 1999; 25: 431-3.
The canal was accessed, and pulp extirpation performed before the placement of intracanal nonsetting
calcium hydroxide by the general dental practitioner (GDP).
