Abstract Background The present study compares the apical microleakage of three different root-end filling materials in which the retrograde cavity is prepared by two different burs. Methods Eighty extracted single rooted maxillary and mandibular premolars were taken. Root canal treatment was completed. Apical 3 mm of all the teeth were resected with diamond disk. The tooth were divided into four groups with two subgroups for each group containing 10 tooth (N= 10) as: Group IA (Negative Control and IB (Positive Control); Group IIA and IIB: Prepared with round carbide bur and round diamond bur respectively, filled with GIC; Group IIIA and IIIB: Prepared with round carbide bur and round diamond bur respectively, filled with MTA; Group IVA and IVB: Prepared with round carbide bur and round diamond bur, filled with Biodentine. After applying two coats of nail varnish leaving apical 3 mm (except for negative control group) all teeth were immersed in 2% methylene blue for 3 days and again in 65% nitric acid for next 3 days for extraction of dye. The obtained solution was then transferred to eppendorf tube and centrifuged in microcentrifuges at 14,000 revolution per minutes (RPM) for 5 minutes. Optical density or absorbance of the supernatant solution was measured with UV spectrophotometer at 550 nm. Results The absorbance of the supernatant solution after dye extraction is decreasing in the order of positive control> GIC> MTA> Biodentine> negative control group. The significant difference was observed between GIC and MTA (p=0.0001) and GIC and Biodentine (p=0.0001) with two different burs but statistically non-significant difference was observed between MTA and Biodentine with Carbide bur (p=0.127) and Diamond bur (p=0.496) respectively. Conclusions Within the limitations of the present study, it can be concluded that Biodentine and MTA showed less microleakage as compared to GIC. There is no significant difference between mean microleakage of MTA and Biodentine. However, the mean OD of the Biodentine was least of all evaluated materials. Preparation of the root-end using round carbide bur as well as round diamond burs showed comparable microleakage for all three filling materials.

Abstract Background: To compare, in vitro, the bioceramic materials (MTA and BC RRM-fast set putty) capacity to prevent microleakage of Enterococcus faecalis over time. Methods: An experimental design was made with forty extracted human teeth, coronally cut, and prepared to be placed in a leakage system under sterile conditions. They were randomly divided into an experimental group: thirty teeth (fifteen for retrograde filling material MTA and BC RRM-fast set putty, respectively) and a control group: ten teeth (five positive control, five negative control). The 3 mm root-ends were submerged in a brain-heart infusion broth with a red phenol indicator. The coronal access of each sample was inoculated with E. faecalis every seven days to maintain bacterial viability. The lower chamber was evaluated daily for 30 days to observe the turbidity of the culture medium and establish the presence and day of the filtration. Calculation of the colony-forming units (CFU) was performed for each leaked sample. Results: Of the total samples prepared for each type of bioceramic material, leaked 60.0% (9/15) of the MTA group and 40.0% (6/15) of the BC RRM-fast set putty group. All positive controls filtered on the first day of evaluation, while 20% (1/5) of the negative control leaked in the second week. There was no significant difference in leakage between the bioceramic material types, nor concerning the bacterial count and the type of cement used (p = 0.101). Conclusions: This study suggests that BC RRM-fast set putty and MTA have a similar sealing capacity when used as a retrograde filling material in vitro.

ABSTRACT Background: In diabetes mellitus, hyperglycemia causes oxidative stress that enhances the production of free radicals. The presence of higher levels of malondialdehyde (MDA) indicates the rise of free radicals. On the basis of its role as an antioxidant that binds free radicals and reduces the level of malondialdehyde (MDA). Soursop leaf can act as an antidiabetic agent. This study aimed to examine the efficacy of soursop leaf extract (Annona muricata L.) to decrease the level of MDA level in alloxan-induced diabetic rats (Rattus norvegicus). Subjects and Method: This was an experiment study using pre- and pro-test with control group design. Total of 30 rats were selected for this study and divided into five groups of treatment i.e. group I was given distilled water and standard feed (Negative Control/KI), group II was given vitamin E 150 IU/kgBW/day (Positive Control/KII), group III was given soursop leaf extract 75 mg/kgBW/day (KIII), group IV was given soursop leaf extract 150 mg/kgBW/day (KIV), and group V was given soursop leaf extract 300 mg/kgBW/day (KV). Each group consisted of 5 rats and was given soursop leaf extract for 21 days after being induced by alloxan and high-fat diet. The data were analyzed using Mann-Whitney test. Results: There was a significant difference in KI group compared to KII, KIII, KIV, and KV groups. Soursop leaf extract of 150 mg/kgBW/day was the most effective dose to reduce MDA level in pancreatic rat. Conclusion: Soursop leaf extract of 150 mg/kgBW/day is the most effective dose on pancreatic MDA level reduction.
