Sealing ability of MTA, CPM, and MBPc as root-end filling materials: a bacterial leakage study.

Medeiros PL, Bernardineli N, Cavenago BC, Torres SA, Duarte MA, Bramante CM, Marciano MA - J Appl Oral Sci (2016)

Bottom Line: The MBPc showed significantly less bacterial leakage compared with the MTA group (p<0.05).No significant differences were found between the CPM and the other groups.Conclusions The epoxy resin-based cement MBPc had lower bacterial leakage compared with the calcium silicate-based cements MTA and CPM.

ABSTRACT
Objectives To evaluate the sealing ability of three root-end filling materials (white MTA, CPM, and MBPc) using an Enterococcus faecalis leakage model. Material and Methods Seventy single-root extracted human teeth were instrumented and root-ends were resected to prepare 3 mm depth cavities. Root-end preparations were filled with white MTA, CPM, and MBPc cements. Enterococcus faecalis was coronally introduced and the apical portion was immersed in BHI culture medium with phenol red indicator. The bacterial leakage was monitored every 24 h for 4 weeks. The statistical analysis was performed using the Wilcoxon-Gehan test (p<0.05). Results All cements showed bacterial leakage after 24 hours, except for the negative control group. The MBPc showed significantly less bacterial leakage compared with the MTA group (p<0.05). No significant differences were found between the CPM and the other groups. Conclusions The epoxy resin-based cement MBPc had lower bacterial leakage compared with the calcium silicate-based cements MTA and CPM.

f01: Composition of the evaluated cements

Mentions: The composition of the evaluated cements is present in Figure 1. Cements were manipulated by following the manufacturer’s instructions. They were incrementally inserted into the root-end cavities and vertically compacted using a hand plugger. Specimens were stored in 100% of humidity at 37°C for one week to allow the cements to set. For negative control (n=5), the entire root surface was coated with two layers of nail varnish (Colorama, L’Oréal, São Paulo, São Paulo, Brazil) after filling all root-end cavities. Positive control (n=5) was left with unfilled root-end cavities.
