Abstract

AIMS:

The aim of the present study was to evaluate and compare the sealing ability of root canal obturation after the application of fluoride varnish (MI Varnish) containing 5% sodium fluoride and casein phosphopeptide-amorphous calcium phosphate, fluoride varnish, and AH Plus and AH-Plus as root canal sealer by bacterial penetration test.

MATERIALS AND METHODS:

Root canals of 65 single-rooted and single-canalled teeth were prepared. They were divided into three experimental groups (n = 15) and two control groups (n = 10). The root canal walls in Group I were coated with AH Plus, Group II were coated with AH Plus and fluoride varnish, and Group III were coated with fluoride varnish. All the teeth were obturated with gutta-percha using the lateral condensation technique. Enterococcus faecalis were used as test bacteria to determine the leakage during 100 days.

STATISTICAL ANALYSIS:

The data were analyzed using log-rank test and Kaplan-Meier survival analysis.

RESULTS:

Group III showed significantly less bacterial penetration as compared to Group I (P = 0.01) and Group II (P = 0.03). However, there was no statistical significance between Groups I and II (P = 0.672).

CONCLUSIONS:

It can be concluded from the present study that fluoride varnish can be used as a root canal sealer. However, further in vitro and in vivo studies are required.
