Abstract

Abstract:

Objective

To observe and compare the clinical efficacy of direct pulp capping with iRoot BP Plus and mineral trioxide aggregate (MTA) in young permanent teeth with deep caries and exposed pulp.

Methods

Thirty young permanent teeth in 7- to 15-year-old patients, were randomly divided into iRoot BP Plus group (fifteen teeth) and MTA group (fifteen teeth) . iRoot BP Plus and MTA were used to direct cap on the exposed pulp. Clinical symptoms, pulp vitality, the formation of dentinal bridge, and the closing of the rupture of teeth marrow were evaluated in 1 year. The percentage of root canal calcification bridges formation and the survival rate of the pulp were compared and evaluated by Wilcoxon rank sum test. And Student′s t test was used for the statistical analysis of the operation time of capping.

Results

After 1 year, the survival rate of the pulp in iRoot BP Plus group was 86.7%, which was 80.0% in MTA group, while there was no significant difference between two group (χ²= 0.240, P= 0.624) . The operation time of capping in iRoot BP Plus group and MTA group were (2.55 ± 0.33) min and (4.88 ± 0.25) min. Thus, the operation time of capping in iRoot BP Plus group was significantly shorter than MTA group (t=-21.983, P<0.001) . The times of visit of iRoot BP Plus group was less than MTA group in this study. After 3 months of follow-up, the rate of calcification formation in iRoot BP plus group and MTA group were respectively 80% and 73.3% (χ²= 0.186, P= 0.666) . After 6 months, the formation rates were 86.7% and 80% (χ²= 0.240, P= 0.624) , respectively, and after 12 months the formation rates were 86.7% and 80% (χ²= 0.240, P= 0.624) , respectively. There was no significant difference for the rate of calcification formation between the two groups. The teeth were discolored in the MTA group, and no tooth discoloration occurred in the iRoot BP Plus group.

Conclusions

Both iRoot BP Plus and MTA are excellent direct pulp capping agents. The clinical effect of iRoot BP Plus is similar to MTA. The operation of direct pulp capping with iRoot BP Plus is quicker and easier than MTA.
