Comparative evaluation of different restorative material used as intra orifice barrier in preventing coronal microleakage: An in vitro study

AUTHOR(S): Gaurav Kumar and Avneet Dengre
ABSTRACT:The aim of this in vitro study was to compare the efficacy of three different restorative material employed as intra orifice barrier after completion of endodontic treatment. Twenty extracted human maxillary and mandibular molars were divided randomly into four groups of five teeth each after completion of standard endodontic treatment. While the first group acted as positive control it was left unsealed coronally. In the rest of three groups, 3mm of Gutta-percha was seared from the canals and restored with one of the three restorative material acting as intra orifice barrier: Conventional GIC, Light cure (LC) GIC and flowable composite. The samples were then stored for 1 day and then immersed in (2%) methylene blue dye for 7 days. Teeth were longitudinally sectioned and examined under a stereomicroscope. The results showed that conventional GIC had the least mean dye penetration while highest dye penetration was observed in positive control group. Intra orifice barrier may be effective in preventing coronal micro leakage.
