Background: The COVID-19 first appeared in Wuhan city of China. It was treated as a case of pneumonia having no etiology, first appeared in December 2019. Its spread was at a rapid pace worldwide. It was named as COVID-19 by the World Health Organization on 11 th February 2020, as of 5 th June 2020, there are 87,113 confirmed cases of COVID-19 in Pakistan. Method: A cross-sectional descriptive study was conducted on 196 students of SMBBMU through an online questionnaire. It was self-generated and evaluated by epidemiologists. The questionnaire was developed through the WHO advisory from the Coronavirus disease advice for public: Myth busters. It contains socio-demographic information and Twenty-four (24) questions related to myths and knowledge for COVID-19 and the response of questions was taken on true/false basis. Results: A total of 196 students participated out of which 100 were females and 96 were males, the mean age of the participants was 22.4005 ± 4.97, and 168(85.7%)participants were unmarried. The highest ratio involved in this study was of the first year, which was about 82 (41.8%). The most common source of information was social media (n=118; 60.2%). Overall,77.21% of the students were aware of the myths and realities regarding COVID-19.Data were analyzed through SPSS 24.Conclusion:The students had sound knowledge regarding the myths and realities of COVID-19.It is the responsibility of public health care providers to spread this knowledge into every part of the country through social media and other sources at their disposal.

Background:In the patients of cirrhosis oral health id generally poor and may lead oral infections. Periodontal disease is an infection of structures in mouth that surround the teeth, which is linked with several systemic diseases, including cirrhosis. Objective: To determine the frequency of Periodontitis in patients with cirrhosis at Chandka medical college hospital and Bibi Asifa dental college hospital Larkana.

Objectives: To assess the role of lingual flap in encountering lingual nerve injury during the surgical elimination of lower wisdom tooth. Study Design: Cross Sectional Case Control study. Setting: Department of Oral & Maxillofacial Surgery, Institute of Dentistry, Liaquat University of Medical & Health Sciences Jamshoro / Hyderabad. Period: January 2016 to September 2016. Material & Methods: Subjects were categorized into two categories: Group-A (lingual flap) & group-B (control group) each having 52 patients by Lottery method. In group A an envelope mucoperiosteal flap followed by lingual flap elevation carried out and in group B only envelope flap was carried out. All patients were reviewed on the first postoperative day and again 1 and 3rd week after surgery. At each postoperative visit, patient was examined for sensory nerve impairment of the lingual nerve by same observer. Results: Total 104 cases were studied, all the cases categorized among two groups 52 in each group. In group-A 34 were males and 18 were females, while in group-B 44 were male and 8 were females. There was no significant difference among both groups according to the pre-operative assessment. According to objective findings, lingual nerve paresthesia was found among 2 cases of group A on 1st visit, while no any case was found with nerve injury in group B. Out of 2 cases, one case was improved and only one had presented with complain at 2nd visit and 3rd visit, no significant difference among both groups, p-values were quite insignificant. Conclusion: It was concluded that lingual nerve injury (LNI) occurred among few cases of lingual flap group which was insignificantly higher as compare to control group, but the nature of injury was temporary.

Objective: To determine the soft tissue lip profile with Steiner (S) and Ricketts (E) lip analysis in patients with skeletal and dental class i occlusion at LUMHS Methodology: This descriptive study was done at department of Orthodontic, Liaquat University of medical and health sciences Jamshoro/Hyderabad, from august 2014 to august 2015. Individuals having age range of 18–30 years with dental and skeletal occlusion class I, competent lips involving facial profile, without history of preceding orthodontic treatment, mal and crowded aligned teeth and either of gender were included. To evaluate hard soft and tissue lip profile, the cephalometric analysis was done using radiographs, traced manually on matte acetate sheets with thicknesses of 0.003, measurements of 8x10 under direct inspection on an illuminator. SPSS version 26 was used for data analyzed. Results: A total of 100 patients were enrolled in the study their average age was 22±1.2 years. Males were 41% and females were 59%. The overall average of SNA angle was 81.866±1.199 and average of SNB angle was 80.667 ±1.27. Average of ANB angle, S line to upper lip, S line to the lower lip and E line to upper lip were 1.167 ±1.028, 1.067 ±1.006 mm, 1.917±1.369 mm, and 3.2±1.96 mm, respectively, while average of lower lip was 2.80+2.83. Conclusion: In terms of soft tissue lip profile with Ricketts (E) and Steiner (S) lip analysis among patients with dental and skeletal occlusion class I, the Antero-posterior position of lower and upper lip regarding E-line was 2.80 +2.83mm and 3.2+1.96 mm, respectively, and Antero-posterior position of lower and upper lip regarding S-line was 2.16+1.34mm and 1.30+1.019 mm, respectively. According to gender, there was statistically no significant variance. Keywords: Lip profile, skeletal, dental, occlusion class I
