Clinical outcome of direct pulp capping by using mineral trioxide aggregate and calcium hydroxide in the mature permanent teeth during the carious tissue removal.

Objective: To compare the clinical outcome in between the mineral trioxide aggregate (MTA) and calcium hydroxide (CaOH) during the direct pulp capping in mature permanent teeth. Study Design: Comparative Cross Sectional. Setting: Department of Operative Dentistry and Endodontics, Institute of Dentistry, Liaquat University of Medical & Health Sciences Jamshoro / Hyderabad. Period: January 2022 to December 2022. Material & Methods: We included all patients who had vital pulp, reversible pulpitis, mature teeth with closed apex, and were between the ages of 18 and 35, regardless of gender. Two groups of patients with equal numbers were formed. Those in groups A and B. Patients in Group A received MTA treatment, whereas those in Group B received CaOH treatment. Patients in both groups were encouraged to follow up to check on the discomfort and sensitivity of the tooth after 24 hours, a week, three months and six months. Data were gathered using a research proforma. Results: The mean age of the patients was 27.13+4.59 years in CaOH group and 27.43+4.40 years in MTA group. Pre- operatively the most of the patients had moderate to severe pain in both groups as 40.0% and 46.7% in CaOH group and 20.0% and 80.0% in MTA group respectively. Severity of the post-operative pain was less in MTA group while findings were statistically insignificant (p-0.143). On the pain assessment after 3 months, only 13.3% cases had mild pain in CaOH group, while no any case found with pain in MTA group (p-0.038). Post operative pain on 7th month was almost decreased complete in both groups. Test validity was positive in all of the cases till 6th months follow-up, which indicted that no nay cases had developed narcosis after treatment in both groups. Furthermore, in this study, there was no any cases found with radiological abnormalities during follow- up of 24 hours to 6 month post-operatively in both groups. Conclusion: After direct pulp capping in adult permanent teeth, both mineral trioxide aggregate and calcium hydroxide were demonstrated to be effective. However, MTA seems to be more effective than calcium hydroxide in preserving long-term pulp vitality.
