Introduction: Cumin (Nigella Sativa) seed oil extract has some ingredients which have antimicrobial effects. The essential oils present in cumin act as antimicrobial agent and it influence on different type of Gram-negative and Gram-positive bacteria and also viruses, parasites and fungi. This study aimed to investigate the antimicrobial properties of cumin extract in disinfecting dentistry surfaces. Material and Methods: This study was performed experimentally and had three groups of cumin extract, Deconex and control group. For each of these groups, 12 culture media were prepared and we counted the colonies created in 24 hours and 48 hours and significance level was assessed using SPSS software and t-test.    Results: At 24 hours, there was a significant difference between the bacterial colony counts of the petri dishes from Cumin Seed (Nigella Sativa) Oil Extract at 5.83 and the Deconex at 0. And at 48 hours, there was also a significant difference since the bacterial colony count on the petri dishes with Cumin (Nigella Sativa) Oil Extract was too many to count and a 0.83 bacterial colony count for the petri dishes with the Deconex. Conclusion: The Cumin (Nigella Sativa) seed oil extract is not suitable to use as an alternative disinfectant of dental surfaces lonely. But some of its ingredients such as thymoquinone and hydroquinone can be used to produce a disinfecting solution.

Nigella sativa (NS), commonly known as black cumin, has been used for medicinal purposes. Traditionally the seeds and its oil are used in several diseases. The greatest part of the remedial properties of this plant is due to the presence of thymoquinone (TQ) which is a major active chemical component of the essential oil. The current study performed to evaluate the effect of Nigella sativa Oil (NSO) extract on the neurotoxic and hepatotoxic potentials from Valproic acid (VPA) administration. Also we summarize recent findings emphasizing the role of main neurotoxic and hepatotoxic markers and oxidative stress in study’s case. Neurotoxicity was induced by VPA at dose of (500 mg/kg b.wt) by gastric intubation daily for 30 day. These rats received NSO extract was given orally at dose of (0.5 ml/kg b.wt) daily for 30 days after VPA administration. The current results revealed that NSO extract treatment ameliorated significantly the elevated levels of the neurotoxic and hepatotoxic biomarkers which elevated as a result to VPA administration. Moreover, NSO extract treatment ameliorated the non-enzymatic antioxidant, brain and liver lipid peroxidation (LPO) and glutathione (GSH) concentration and the enzymatic antioxidant, brain and liver catalase(CAT) activity.

In this study, the gross composition and mineral content of Nigella sativa seed powder (NSP) and fatty acid composition of Nigella sativa oil (NSO) were investigated. The ability of NSP, extract (NSE) and NSO in reducing the effects of cisplatin-induced renal toxicity in Sprague-Dawley rats were examined. The obtained results showed that NSP contains high amounts of carbohydrates, protein, and fiber while NSO has higher amounts of linoleicacid, oleic acid, and myristic acid. Rats treated with NSP, NSO, and NSE exhibitedreducedserum levels of urea, creatinine, and potassium, and a significant increase of Na, Na/K, vitamin D, nutritional markers, and antioxidant enzymes compared to the cisplatin-induced renal toxicity group receiving no Nigella sativa seed treatment. This study determined that all powder, oil, and extracts of N. sativa contain potent bioactive components that may aid in treatment against cisplatininduced renal toxicity in rats.

This study investigates the antibacterial effects of erbium chromium laser at 2780 nm, silver nanoparticles, and erbium chromium along with silver nanoparticles on Enterococcus faecalis in comparison with sodium hypochlorite. In the present study, 90 extracted human single-rooted teeth were selected and standardized to a length of 15 mm. The canals were prepared by V-taper Gold rotary files and then incubated with E. faecalis for 21 days. The samples were divided into four experimental groups including hypochlorite sodium, silver nanoparticle, erbium chromium laser, and erbium chromium laser along with silver nanoparticle groups. Results showed that there was a significant reduction in colony count for all groups after interventions. Moreover, there was a significant reduction in the colony count for sodium hypochlorite group in comparison with another groups, and this group showed the highest reduction of colony count. There was a significant difference between silver nanoparticles and erbium chromium laser groups in colony count. According to the results, the silver nanoparticles offered strong antibacterial effects on E. faecalis and therefore can decrease bacterial colonies, while the use of the laser, despite the reduction of the bacterial colony, could not be sufficiently used for disinfection of root canal system.

Background: Dental infections were caused by the bacterium overgrowth on the surface of the tooth, and treatment should always be set up to prevent this development.Antibiotics have long been used as a conventional antibacterial medication, but their overuse has resulted in microbes gaining resistance to many of the antibiotics, trying to make many commercialized therapeutic remedies ineffectual and resulting to infection recurrence. In this regard we aim to analyze the antibacterial activity of nigella sativa seeds’ and fenugreek seed extract rinses against S. mutans' colonies. Methodology: It was a preclinical experimental study conducted at Baqai Medical and Dental College Karachi., from January - June 2021. Calculated sample size was n = 80 Consecutive sampling technique was used. Plaque of study participants was collected on sterile strips that was transported to laboratory for culture in sterile containers.The extract of Fenugreek seed and nigella sativa seed was kept in an airtight bottle and stored in a refrigerator till usage. The extracts were diluted in distilled water in 1:4 (Extract: Distilled water). Study participants were instructed to not brush their teeth before sampling. Study participants were divided into four groups (negative control, positive control, fenugreek seed extract group and Nigella sativa group) each group had 20 participants. Diluted Fenugreek seed extract and Nigella sativa extract was given to experimental groups for rinses. Results: There was significant decrease in number of colonies in positive controls, fenugreek seed extract group and nigella sativa extract group and there was no change in number of colonies in control group. Furthermore, the analysis showed significant (p-value = 0.001) difference among the groups followed by post hoc analysis. Post hoc analysis showed no difference between positive control, fenugreek seed extract group and nigella sativa group. Conclusion: Fenugreek seed extract and Nigella Sativa seed extract showed comparable antibacterial properties. Also, the effect was found to be similar to commercially available mouth rinse.
