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.

f03: Number of samples leaked during a period of 120 days

Mentions: The criteria evaluated with experimental periods are shown in Figure 3. All cements showed bacterial leakage after 24 hours, except for the negative control group. The MTA showed a higher number of specimens that leaked compared with the MBPc group (p<0.05). Statistical similarities for bacterial leakage were found between the CPM and the MBPc and also the MTA (p>0.05). After 31 days until the final period, only one specimen (MBPc) among all groups showed infiltration.
