COMPARATIVE EVALUATION OF MICROLEAKAGE OF BIODENTINE AND GERISTORE ROOT END FILLING MATERIALS IN DRY, SALIVA AND BLOOD CONTAMINATED ENVIRONMENTS – A FLUORESCENT MICROSCOPE STUDY.

Abstract

Aim: The aim of this in vitro study was to compare and evaluate the microleakage of Biodentine and Geristore root end lling materials in dry, saliva and blood contaminated environment using uorescent microscope. After removing Materials & methods: the anatomical crowns of ninety extracted human maxillary central incisors, their root canals were instrumented and obturated. The apical 3 mm of each root was resected, and a standardized root end cavity was prepared using a # 8 round bur. The roots were alienated into three equal subgroups for each material and the root end lling was performed in different environments namely dry, saliva contaminated, and blood contaminated. Samples were immersed in 0.2% Rhodamine B dye for 48 hrs. Roots were sectioned longitudinally and examined under a uorescent microscope to measure the linear dye penetration. Geristore showed higher microleakage compared to Biodentine in dry (0.47±0.516), sa Results: liva (1 ± 0.65) and blood (1.27 ± 0.59) sub-groups. Statistically no signicant difference was seen between the Biodentine and Geristore groups in dry sub group (p=0.52), in saliva sub group (p=0.45) and in blood sub group (p=0.054). Microleakage was observed in both the tested group Conclusion: s. Biodentine exhibited the least apical leakage value, while Geristore exhibited the maximum apical leakage value. Statistical signicant difference was seen between dry and blood subgroup in Geristore group, whereas there was no signicant difference between any subgroups in Biodentine group.
