Clinical and Salivary Antioxidant Effects of Matcha Tea in Patients with Gingivitis: A Randomized Controlled Trial
...Show More Authors
Introduction

Gingivitis, the initial stage of periodontal disease, is characterised by inflammation driven by dental biofilm and associated with oxidative stress. Matcha tea, a powdered green tea rich in antioxidants, has shown potential health benefits. This study aimed to investigate the effect of Matcha tea consumption on clinical periodontal parameters and salivary antioxidant levels in patients with gingivitis.

Methods

A randomised controlled clinical trial was conducted with 41 participants diagnosed with gingivitis. Participants were randomly allocated to a Matcha tea group (n=21) who consumed two cups of Matcha tea daily for 30 days, or a control group (n=20) who received standard oral hygiene instructions. Primary outcomes were clinical periodontal parameters (Plaque Index [PI], Bleeding on Probing percentage [BOP%], Gingival Index [GI]), and secondary outcomes were salivary levels of Malondialdehyde (MDA), Superoxide Dismutase (SOD), and Glutathione Peroxidase 1 (GPX1), assessed at baseline and after 30 days.

Results

Both groups showed significant within-group improvements in PI, BOP%, and GI at the 30-day follow-up (p<0.01). However, there were no statistically significant differences in these clinical parameters between the Matcha tea and control groups at the endpoint. The Matcha tea group exhibited a significant reduction in salivary MDA levels (p=0.002) and significantly higher salivary SOD (p=0.047) and GPX1 (p=0.027) levels compared to the control group at the 30-day follow-up.

Discussion

The biochemical improvements are attributed to Matcha's potent antioxidants, which favorably modulate the oral redox balance. The lack of superior clinical outcomes suggests that the profound effect of mechanical plaque control may have overshadowed any adjunctive benefits from Matcha within the 30-day trial. This highlights a potential disconnect between systemic antioxidant modulation and localised clinical changes in gingivitis management.

Conclusion

Daily consumption of Matcha tea for one month favorably modulated salivary antioxidant biomarkers in patients with gingivitis, reducing lipid peroxidation and increasing antioxidant enzyme levels. However, these biochemical changes did not translate into statistically significant differences in clinical periodontal parameters beyond standard oral hygiene within this study's timeframe.

Study the Effect Different Radioactive Dose on Mechanical Properties of Composite Material from Novolak Resin Exposure to High – Energy Radiation
...Show More Authors

The research involves using phenol – formaldehyde (Novolak) resin as matrix for making composite material, while glass fiber type (E) was used as reinforcing materials. The specimen of the composite material is reinforced with (60%) ratio of glass fiber.

      The impregnation method is used in test sample preparation, using molding by pressure presses.

      All samples were exposure to (Co60) gamma rays of an average energy (2.5)Mev. The total doses were (208, 312 and 728) KGy.

      The mechanical tests (bending, bending strength, shear force, impact strength and surface indentation) were performed on un irradiated and irrad

Dust Effect on the Efficiency of Silicon Mono Crystalline Solar Modules at Different Tilt Angles at Al-Jadryia Climate Conditions
...Show More Authors

Solar energy usage in Iraq is facing many issues; one of those is the accumulation “of the dust on the surface of the solar module which” would highly lower its efficiency. The present work study the effect of dust accumulation” on installing fixed solar modules with different inclined angles 15o, 33o, 45o, 60o. Evaluation of the solar modules performance under different circumstance conditions such as rain, wind and humidity are considered in study of dust effect on solar module performance. The results show that the lowest output average efficiencies of solar modules occurs at 15o horizontally inclined angle are 7.4% , 6.7% , 8.0% , 8.1%, and 8.4% for the cor

Multiple Mixing Ratios of Gamma Rays Reaction 32 70 70 33 Ge p n As (, ) γ Using a2-ratio Method.
...Show More Authors

The δ-mixing of γ-transitions in 70As populated in the 32 70 70 33 Ge p n As (, ) γ reaction is calculated in the present work by using the a2-ratio methods. In one work we applied this method for two cases, the first one is for pure transition and the sacend one is for non pure transition, We take into account the experimental a2-coefficient for previous works and δ -values for one transition only.The results obtained are, in general, in a good agreement within associated errors, with those reported previously , the discrepancies that occur are due to inaccuracies existing in the experimental data of the previous works.

The Effect of The Illustration Program on Fashion Design Inspired by Historical Costumes: تهاني ناصر العجاجي -هدى عبد العزيز المقرن
...Show More Authors

This research aims to identify the role and impact of illustrations in contemporary fashion design inspired by historical costumes. Historical fashion aesthetics are adapted to design drawings. The experimental method was followed and a sample of 31 students in the department of fashion and textile design, third level were selected. Each student carried out two original historical and contemporary design. The models were executed two times: one with the usage of the program and the other without program help. The tools that were used are the program, the scale, the pre-skill test, and the post-skill test. One of the most relevant results of the research is the possibility of using historical costumes to highlight creativity and innovatio

“As if sky was blue”: An Eco-Marxist Reading of Caryl Churchill’s Play Not Not Not Not Not Enough Oxygen
...Show More Authors

 Humanity is confronted with a growing array of environmental challenges that demand immediate attention and cannot be disregarded. One of the issues the world faces is air pollution, which presents a significant risk to both the environment and human well-being. The capitalist system has a great impact on the exacerbation of air pollution and environmental deterioration. This impact is reflected in Caryl Churchill’s post-apocalyptic play Not Not Not Not Not Enough Oxygen (1971). The play presents a futuristic scenario in which humanity faces grave consequences due to the polluting practices of capitalism and the unsustainable exploitation of natural resources. It depicts a future in which environmental degradation drives people

The imposition of (state) policy on the South Kuril Islands.In the Pacific was a subject
of borders dispute between Japan and Soviet Union which appeared clearly afterthe second
Great War and during the cold war. Despite the end of the Cold War and the collapse of the
Soviet Union in 1991, this conflict has continued, thus both countries had to made a historic
and legitimate claims to demand the rights of sovereignty and ownership of four islands
occupied by the Soviet Union after World War II under the international conventions and
treaties, but these claims are proven failures through the continuation of the regional conflict.

The aim of this study is to show the concepts of nuclear shape and the geometrical picture to the even-even nuclei of 164,166,168E isotopes in the context of the Interacting boson Model IBM-1. The energy spectra were calculated and the effective charge values (eB) of the electromagnetic transition strength were obtained and used to calculate the B(E2) values of the electromagnetic transitions and the quadrupole moment Q of 2+ -states. The Hamiltonian parameters were calculated by taking in account the properties of these nuclei. Comparison were made with the available experimental data and included in tables. The geometrical picture of these nuclei were looked at by calculating the deformation which were represented by the potentia
