Introduction: The primary objective of any root end filling material is to seal the apical
region to avoid any kinds of bacterial infiltration or their by-products from the
supporting periodontal structures into the root canal system.
Materials and Methodology: For the study purpose, sixty mandibular premolars were
selected which were extracted for orthodontic reasons. The root surfaces were sought to
be cleaned and the soft tissue remnants present as debris were removed help of
Ultrasonic scaler and teeth were stored in distilled water until further use. The
materials that were intended to be studied in this research were manipulated as per the
manufacturer’s instructions and the cavities were filled respectively. The specimens
were then coated with 2 coats of nail varnish except at the 1 mm apical area & then they
were allowed to be dried.
Results: Group A: Since it is a control group, no material was placed. All
stereomicroscopic images for the control group demonstrated a relative amount of dye
penetration. Both Group B and C showed microleakage, where Giomer and Biodentine
showed microleakage but the difference was not statistically significant. Biodentine is
considered as better root-end materials since it showed lesser microleakage than
Giomer.
Conclusion: Both the root-end filling materials such as Giomer and Biodentine revealed
the presence of microleakage but the results were not observed to be statistically
significant. Comparatively Biodentine possessed lesser microleakage than Giomer and it
is considered to be better. Therefore, it can be effectively used as a retrograde filling
material with better results.
