Aims and Objectives: The aim of this study was to compare the clinical performance of mineral trioxide aggregate (MTA) and calcium hydroxide as indirect pulp-capping agents in permanent teeth. Materials and Methods: Search strategy includes randomized control trials and clinical trials from the databases of PubMed Central, Cochrane, EBSCO, and MEDLINE from January 1998 to May 2018. A total of six clinical trials that met all inclusion criteria were included in this systematic review. Meta-analysis was performed for three among the included studies. The primary clinical outcome of the included studies was to evaluate the pulp vitality with a normal response to thermal, electrical, and tactile tests without signs of spontaneous pain. The radiological outcome was to evaluate the absence of periapical radiolucency, periodontal ligament space widening, and the dentin bridge formation. The primary and predominant results were assessed based on the success or failure of pulp capping. The restorations were considered failure when there are clinical symptoms such as pain and tenderness and radiographic evidence of radiolucency in periapical region or widening of periodontal ligament. Results: In the six trials that are included, two studies are judged as low risk and four as medium risk of bias. With the help of meta-analysis, the evidence produced concluded that after six-month and one-year follow-up there was no statistically significant difference between MTA and calcium hydroxide as an indirect pulp-capping material. Conclusion: This systematic review of the available evidence reveals that MTA and calcium hydroxide demonstrated good consistent endurance in clinical studies and indistinguishable performance.
