The application of MTA and calcium hydroxide showed similar clinical performance over a 24-month period.

Objective: This clinical study aimed to assess the efficacies of mineral trioxide aggregate (MTA) and calcium hydroxide [Ca(OH)2] in the treatment of deep carious lesions by the direct complete caries removal technique.
Methods and Materials: A total of 100 permanent molar/premolar teeth were capped with either Ca(OH)2
(n=49) or MTA (n=51) and restored with composite resin in 73 patients.
Periapical radiographs were acquired prior to the treatment as well as
at six, 12, and 24 months posttreatment. Two calibrated examiners
performed the clinical and radiographic assessment of the periapical
pathology and pulpal symptoms. Intergroup comparisons of the observed
values were performed using the Fisher exact test. Significance was
predetermined at α = 0.05.
Results:
The recall rates were 100% at six and 12 months post treatment and 98.6%
at 24 months post treatment. Four teeth capped with Ca(OH)2
(two each at six and 12 months post treatment) and two capped with MTA
(one each at 12 and 24 months post treatment) received endodontic
emergency treatment because of symptoms of irreversible pulpitis, which
were clinically and/or radiographically established. There were no
significant differences in pulp vitality between the two pulp-capping
agents at six, 12, or 24 months post treatment (p=0.238, p=0.606, and p=0.427, respectively).
Conclusions: Both pulp-capping materials were found to be clinically acceptable at 24 months post treatment.
