This study aims to evaluate the sealing ability of Mineral Trioxide Aggregate Repair HP, Biodentine and White Mineral Trioxide Aggregate(WMTA) as furcation repair materials by using Ultraviolet- Spectrophotometric analysis. A total of 80 freshly extracted human permanent mandibular first and second molar teeth were included. Teeth were decoronated 3mm above the cemento-enamel junction and roots were amputated 3mm below the furcation.  Endodontic access cavity opening was done and root canal orifices were sealed with sticky wax. Artificial perforations were made in furcation areas of teeth using round bur.80 specimens were divided into 3 Experimental groups with 20 specimens per group; Group A (MTA Repair HP), Group B (Biodentine), Group C (WMTA) used as furcation repair materials and the remaining 20 specimens were equally divided between Positive control and Negative control groups. Specimens were immersed in Indian ink dye for 48hours and were then subjected to dye extraction method by completely dissolving the teeth in 65% nitric acid and the obtained solutions were analysed using Ultraviolet-Spectrophotometer and readings were recorded as absorbance units. Obtained data was statistically analysed using One-way ANOVA and Tukey’s-Post hoc tests.
