Objective: To study the effectiveness of periodontal dressing on different clinical periodontal parameters after scaling and root planning. Study Design: Randomized Controlled Trial. Setting: Department of Periodontology, Multan Medical & Dental College, Multan. Period: May to July 2020. Material & Methods: Thirty three patients of both genders between ages 30-60 were included. Five clinical parameters were measured at baseline. These variables were recorded by University Of Michigan “O’’ Probe with William’s Markings. The measurements were executed by a single, trained and calibrated examiner. Right and left quadrants of Maxilla and Mandible of the same patient were selected as the test and control sites respectively through random selection by lottery method. The maxillary and mandibular test sides were covered with periodontal dressing for 07 days, later the dressing was detached. After 12 weeks, all clinical parameters were recorded again by the same examiner. Results: Mean age was found to be 45.28 years in males and 41.27 years in females. The mean Kappa value of intra-examiner reliability was identified as 0.95. In comparison to control group, test group showed a highly significant improvement in all five tested periodontal variables when the values were compared at base line and then after 12 weeks. Conclusion: Periodontal dressing has significantly improved the clinical outcomes and the periodontal parameters after Scaling and Root Planning procedures.
This study systematically examines the influence of length of dual splitter plates placed at front and rear sides of two sideby-side square cylinders on flow features and fluid force reduction. The Reynolds number is kept at 150 for all computations, and the separation ratio and splitter plate length are varied from 0.5 to 5 and 1 to 5, respectively. The method of investigation is the single-relaxation-time lattice Boltzmann method. The vortex shedding suppression phenomenon occurred due to the presence of dual splitter plates. It is found that the increase in splitter plate length influences the wake structure and increases the wake length by stabilizing the shear layers before rolling up. It is also found that at small separation ratios by placing the dual splitter plates stabilize the flow. The length of splitter plates for minimal drag on the cylinders is found for each separation ratio. Significant reduction in the drag forces is found for both cylinders. At the optimum position the drag coefficient of lower cylinder and upper cylinder is reduced by 45 and 62%, respectively, at separation ratio 0.5 and splitter plate's length 5. Systematic analysis shows that the splitter plates not only significantly reduce the drag on the cylinders, but also considerably suppress the vortex shedding.
Objective: To investigate the correlation between capillary blood oxygen saturation and Computerized tomography (CT) severity index in patients with Covid-19 pneumonia. Study Design: Cross Sectional study. Setting: Ibne-sina Hospital Multan Medical & Dental College Multan. Period: 1st June 2020 to 1st June 2021. Material & Methods: A cross-sectional analytical study was conducted at the COVID-19 ward of Ibne-sina hospital Multan Medical & Dental College Multan for 1 year. At the time of admission, all capillary oxygen saturation of all the included patients was measured. Pulmonary CT scans were then performed on these patients and CT severity index was calculated. SPSS was used for data analysis. Results: A total of 170 COVID-19 infected patients were included in the study. At the time of admission, the mean oxygen saturation was found to be 88.9% ± 6.53%. Whereas, the mean severity index was15.01 ± 7.79. 22 patients had hypoxia when presented in hospital and a significantly high iCT severity index was found in these patients (p=0.001). Chronic obstructive pulmonary disease (COPD), hypertension, and diabetes were significantly related to reduced blood oxygen saturation (p<0.05). Whereas, patients with hypertension had significantly raised CT scores. A significant inverse correlation was found between capillary oxygen saturation and CT severity index (r = −0.41, p < 0.01). Conclusions: The study revealed a significant inverse correlation between capillary oxygen saturation and CT severity index. Moreover, it was found that underlying commodities (I.e past medical history) can also affect the CT severity index.
