Abstract

Context:

An intraorifice barrier after endodontic therapy could remarkably mitigate the movement of bacteria and their by-products and improve the long-term prognosis of a root canal treated teeth by serving as barriers against fluid and bacterial ingress.

Aims:

The idea of the present study was to compare the coronal microleakage in teeth with 2-mm and 3mm intraorifice barriers of Bulkfill flowable composite, Glass Ionomer Cement (GIC), Cention and Biodentin under a stereomicroscope.

Methods and Material:

Eighty freshly extracted human single rooted mandibular premolars with single canal were chosen for the study. Teeth were obturated with gutta-percha using AH plus sealer. The teeth were further divided into 5 groups (16 premolars each) on the basis of intraorifice barrier material used: Bulkfill composite, GIC, Cention, Biodentin and control group. These groups were further subdivided into 2 subgroups each of 2mm and 3mm (8 teeth each) and evaluated under stereomicroscope

Statistical analysis used:

Coronal microleakage was determined under stereomicroscope using 15X magnification. Data were statistically analyzed using two-way ANOVA

Results:

According to the results, GlC at 2mm exhibited the highest micro leakage and least microleakage was shown by Biodentin at 3mm.

Conclusions:

Intraorifice barriers play a key role in reducing coronal microleakage.
