Evaluation and comparison of mineral trioxide aggregate and cold ceramic in primary tooth pulpotomy: Clinical and...

In recent years, many studies have been conducted on different materials for covering the pulp in pulpotomy. Recently, some materials such as Coldceram have been introduced that have the ability to regenerate the pulp. In this study, our aim was to compare the clinical and radiographic success of the pulpotomy of milk molars using MTA and Coldceram over 3-, 6-, and 9-month follow-ups.

In this clinical trial, 42 children aged 4-9 years old who fulfilled the inclusion criteria of the study were selected. Finally, pulpotomy was conducted on 42 teeth using MTA and another 42 teeth using Coldceram in these children. Simultaneously, all teeth were permanently repaired using glass ionomer and metal veneers in the same treatment session. Then, clinical and radiographic evaluation was conducted in 3-, 6-, and 9-month follow-up periods.

None of the teeth showed clinical symptoms at the specified 3-, 6-, and 9-month follow-up times, and clinical success was 100% in both groups. In radiographic evaluation, the numbers of successful treatments were 42/42 (100%) and 41/42 (97%) for the teeth treated with MTA and Coldceram, respectively.

According to this research, both materials were proven to have a 100% clinical success rate, but in the radiographic evaluation, MTA attained a higher success rate compared with Coldceram; however, this difference was not statistically significant (P = 0.36). It is recommended to consider longer follow-ups and larger sample sizes in future studies.
