Evaluation of coronal microleakage in teeth with intraorifice barriers at 2mm and 3mm: An in vitro study

Context:
 An intraorifice barrier after endodontic therapy could remarkably mitigate the movement of bacteria and their by-products improve long-term prognosis a root canal treated teeth by serving as barriers against fluid bacterial ingress.
 Aims:
 The idea present study was to compare coronal microleakage in with 2-mm 3mm Bulkfill flowable composite, Glass Ionomer Cement (GIC), Cention Biodentin under stereomicroscope.
 Methods Material:
 Eighty freshly extracted human single rooted mandibular premolars were chosen for study. Teeth obturated gutta-percha using AH plus sealer. further divided into 5 groups (16 each) on basis material used: GIC, Cention, control group. These subdivided 2 subgroups each 2mm (8 evaluated stereomicroscope
 Statistical analysis used:
 Coronal determined stereomicroscope 15X magnification. Data statistically analyzed two-way ANOVA
 Results:
 According results, GlC at exhibited highest micro leakage least shown 3mm.
 Conclusions:
 Intraorifice play key role reducing microleakage.
