A number of theories have been planned concerning the making of polyorchidism, but the real explanation is still not acknowledged. Here we are going to present a case study of polyorchidism. A 70 years old gentleman complained with left supernumerary testes in the left hemiscrotum. His left hemiscrotum was painless with mass. Polyorchidism without malignancy or any other concomitant features were revealed by both ultrasound and MRI examinations. In most cases the ultrasonograph alone is diagnostic. In complicated cases of polyorchidism MRI may provide additional information.This in-vitro study was done to compare the sealing ability of Mineral trioxide aggregate (MTA), Biodentine, a mixture of MTA and Glass ionomer cement (GIC) in 21 and 11 ratio and MTA CEM, as furcation repair material using a dye extraction leakage model in the department of Conservative Dentistry and Endodontics from January 2020 to December 2020. Eighty five extracted molars with divergent and well formed roots were selected for study and were randomly divided according to the material used for perforation repair. Group A MTA, Group B Biodentine, Group C MTA mixed with GIC in 21 ratio. Group D MTA mixed with GIC in 11 ratio. Group E MTA CEM and 2 control groups. All samples were subjected to orthograde and retrograde methylene blue dye challenge followed by dye extraction with 70 weight % nitric acid. Samples were then analyzed using Ultra violet (UV) Visible Spectrophotometer at 550nm wavelength. The data were subjected to statistical analysis One Way ANOVA (level of significance less then 0.05) and post-hoc tukey test. MTA, Biodentine, Mixture of MTA and GIC in 21 ratio and MTA CEM showed significant less dye absorbance than MTA and GIC in 11 ratio. Within the limitation of the study, the newer mixture of MTA and GIC in 21 ratio showed promising sealing ab
