Patients are very concerned about the lengthy nature of orthodontic treatment. It is necessary to find a non-invasive way to quicken physiologic tooth movement. This study's objective was to assess the effectiveness of low-intensity laser therapy in shortening the time and discomfort of orthodontic treatment. Experimental work: Using a split-mouth study to compare tooth movement with conventional treatment and laser-accelerated orthodontic tooth movement. A patient presenting with a class II division I malocclusion characterized by the misalignment of the upper and lower teeth as classified by Angle’s molar classification system was indicated to undergo fixed orthodontic appliance orthodontic treatment. The treatment plan involved bilateral extraction of the upper first premolar teeth on both sides and distalization of the anterior segment to close the created space. For an experimental investigation, a patient was chosen at random and given right-side radiation using a dual diode laser (810,980 nm wavelength, 100 mW output power). Results: The tooth movement was measured over a period of 15 weeks; the first three orthodontic activations on the study side included scheduled laser treatment (the first month, laser-assisted treatment on days (0,3,7, and 14), the following two months, on days (0 and 14) from the day of orthodontic activation, and another 3 months of follow-up only); it was observed that orthodontic tooth movement was significantly higher in the study side than in the control side, as measured clinically using a digital vernier. We also noticed a considerable decrease in pain levels following a visual analog test. Conclusion: LLLT might clinically considerably speed orthodontic tooth movement and greatly lessen discomfort using the parameter settings employed in this investigation.
The aim of the study is to reveal the effect of the constructivist learning Model on the achievement and reflective thinking of the fifth grade literary Preparatory students in History subject. A random sample was chosen which consisted of 64 students divided into experimental and control groups, each group consisted of 32 students. The experimental group was taught via the constructivist learning model, and the control group was taught via the traditional method. The experiment was lasted for Eight weeks, each week taught two lessons. The researcher adopted the experimental design with partial control. The two groups were equalized statistically. The researcher used two instruments, the achievement test and the reflective thinking test.

The results obtained from the study exhibited that alcoholic extract of Borage officinalis caused inhibition to enzymes activity with all concentrations of the extract. The results also showed that when the concentration of the extract was (0.001 mg/ml), the percentage of inhibition was (4.3% with MAO and 15.2% with AChE) and this percentage increases until reaching up to (74.7% with MAO and 84.18% with AChE) when the concentration of the extract was (0.1 mg/ml).
