Aim: To estimate the frequency of coinciding width of maxillary front teeth and golden proportion ratio in undergraduate students. Study design: Descriptive Cross Sectional Place and Duration of Study: Department of Prosthodontics, Liaquat Medical University Hospital from June 2019 to January2020. Methodology: Total numbers of 96 students with maxillary anterior teeth were selected in this study. Appropriate size of upper maxillary impression of maxillary arch was made using alginate impression material with manufacturer prescribed instructions. The cast was retrieved between one and three hours of pouring. Digital caliper was used to measure for the spaces in the. The final recordings were entered in proforma. The data was analyzed by SPSS version-20. Results: Among the participants 65% were males and 35% females. The mean age of the participants was 21.02±1.88 years. Rate of coinciding was significantly high in 18 to 20 years of age (p=0.032).Coinciding width of maxillary anterior teeth and golden proportion ratio was significantly high in 1st year student (p=0.038) Conclusion: It was concluded that esthetics in dentistry cannot be justified mathematically and individuals should not be standardized. Whereas the dentists should follow few fundamental guidelines in the planning for esthetic treatment, it should be acknowledged that esthetics alters from person to person. That’s why it is important to consider the dento-facial specificities of every person and the inconstant natural tooth proportion during restoration or replacement of the maxillary front teeth.

Background:Knee osteoarthritis and obesity are both major health problems. It is now admitted that the prevalence of knee osteoarthritis gets higher with obesity and that weight loss helps knee function and allows patients to avoid surgery.Objectives:The aim of this study was to study the influence of obesity on knee osteoarthritis features.Methods:A cross-sectional study was conducted in the university hospital Taher Sfar of Tunisia over a period of 6 months. Patients who had knee osteoarthritis confirmed by radiographs were included. Sociodemographic, clinical, radiological and therapeutic data were collected from medical records and visits. Obesity was defined by a body mass index (BMI) ≥30. Functional impairment was assessed by the Womac index and Lequesne index.Results:The study included 186 patients. There were 31 males and 155 femmes. The mean age was 60±10 years. The percentage of obese patients was 53,8%. The mean age was similar in both groups obese and non obese. There were more women in the obese group compared to the non obese group (p=0.0001), more patients who had diabetes mellitus and dyslipidemia (p=0.002). Non-obese patients had a shorter duration of symptoms with no statistical significance (p=0.151). Obese patients had more involvement of both knees (p<0.0001). Obesity did not have an impact on pain severity. Severity of radiological images (p=0,0001) were more frequent in obese patients. Functional impairment was similar in both groups. However, the percentage of patients having a very important functional impairment with Lequesne index was higher in obese patients (p<0.029). Obese patients also needed more physical therapy sessions (p=0.035).Conclusion:Knee osteoarthritis in obese patients is characterized with the femlae gender predominance, bilateral knee involvement, and a more severe images on radiographs. Thus the need for better control of weight and the importance of physical activity.References:[1]Coggon D, Reading I, Croft P, et al. Knee osteoarthritis and obesity.

AbstractCone beam computed tomography (CBCT) provides multiplanar cross-sectional imaging and three-dimensional reconstructions and can be used intraoperatively in a hybrid operating room. In this study, we investigated the feasibility of using a CBCT-scanner for detecting residual stones during percutaneous nephrolithotomy (PCNL). Intraoperative CBCT-scans were made during PCNL procedures from November 2018 until March 2019 in a university hospital. At the point where the urologist would have otherwise ended the procedure, a CBCT-scan was made to image any residual fragments that could not be detected by either nephroscopy or conventional C-arm fluoroscopy. Residual fragments that were visualized on the CBCT-scan were attempted to be extracted additionally. To evaluate the effect of this additional extraction, each CBCT-scan was compared with a regular follow-up CT-scan that was made 4 weeks postoperatively. A total of 19 procedures were analyzed in this study. The mean duration of performing the CBCT-scan, including preparation and interpretation, was 8 min. Additional stone extraction, if applicable, had a mean duration of 11 min. The mean effective dose per CBCT-scan was 7.25 mSv. Additional extraction of residual fragments as imaged on the CBCT-scan occurred in nine procedures (47%). Of the follow-up CT-scans, 63% showed a stone-free status as compared to 47% of the intraoperative CBCT-scans. We conclude that the use of CBCT for the detection of residual stones in PCNL is meaningful, safe, and feasible.

OBJECTIVES: The objective of this study was to compare working length calculated with conventional radiographs and an electronic apex locator (IPEX II) during the root canal treatment of mandibular anterior teeth. METHODOLOGY: A cross-sectional study was done in the Department of Operative Dentistry, Sardar Begum Dental Hospital, Peshawar during February and March 2018. A consecutive sampling technique was used for sampling. Only 30 patients fulfilled the inclusion criteria of our study. Detailed medical and dental history was taken. Only patient fulfilling inclusion criteria were enrolled in the study. Data were analyzed using SPSS version 20. RESULTS: The mean age for patients was 45.33±5.16. 33% out of 30 patients (10) were male and 20 were females. The mean working length calculated from radiographs was 22.25±1.29 (min 20.09-max 24.10). The mean working length calculated by the electronic apex locator (IPEX II) was 22.17±1.28 (min 20.00-max 24.07). The mean difference between working length calculated by radiograph and electronic apex locator was -0.084mm, which means the working length determined by radiographs and by electronic apex locator has no difference in mandibular anterior teeth with single canals. CONCLUSION: Both the methods can be used effectively in endodontics for single-rooted mandibular teeth, but if both are used in combinations can lead to an improvement in the working length accuracy, which may significantly reduce the number of radiographs exposure, and increase the success and comfort for endodontic patients. KEYWORDS: Working Length, Apex Locator, Conventional Radiograph

Abstract This study aimed to estimate both direct medical and indirect costs of treating the Coronavirus disease 2019 (COVID-19) from a societal perspective in the patients at a referral hospital in Fars province as well as the economic burden of COVID-19 in Iran in 2020.Methods:This is a partial economic evaluation and a cross-sectional cost-description study conducted descriptively-analytically and based on the data of the COVID-19 patients referred to a referral university hospital in Fars province between March and July 2020. The data were collected by examining the patients' records and accounting information systems. The subjects included all the inpatients with COVID-19 (477 individuals) who admitted to the medical centre during the four months. Bottom-up costing, incidence-based and income-based human capital approaches were used as the main methodological features of this study.Results: The mean direct medical costs were estimated 28,240,025,968 Rials ($ 1,791,172) in total and 59,203,409 Rials ($ 3,755) per person, a significant part of which (41 %) was that of intensive and general care beds (11,596,217,487 Rials equal to $ 735,510. (The second to which were the costs of medicines and medical consumables (28 %). The mean indirect costs including income loss due to premature death, economic production loss due to hospitalization and job absenteeism during recovery course were estimated 129,870,974 Rials ($ 11634) per person. Furthermore, the economic burden of the disease in the country for inpatient cases with the definitive diagnosis was 22,688,925,933,095 Rial equal to $ 1,439,083,784.Conclusion: The results of this study showed that the severe status of the disease would bring about the extremely high cost of illness in this case. It is estimated that the high prevalence rate of COVID-19 has been imposing a heavy economic burden on the country and health system directly that may result in rationing or painful cost-control approaches.

ABSTRACT Objective To evaluate the indicators duration of anesthesia, operative time and time patients stay in the operating rooms of different surgical specialties at a public university hospital. Methods It was done by a descriptive cross-sectional study based on the operating room database. The following stages were measured: duration of anesthesia, procedure time and patient length of stay in the room of the various specialties. We included surgeries carried out in sequence in the same room, between 7:00 a.m. and 5 p.m., either elective or emergency. We calculated the 80th percentile of the stages, where 80% of procedures were below this value. Results The study measured 8,337 operations of 12 surgical specialties performed within one year. The overall mean duration of anesthesia of all specialties was 178.12±110.46 minutes, and the 80th percentile was 252 minutes. The mean operative time was 130.45±97.23 minutes, and the 80th percentile was 195 minutes. The mean total time of the patient in the operating room was 197.30±113.71 minutes, and the 80th percentile was 285 minutes. Thus, the variation of the overall mean compared to the 80th percentile was 41% for anesthesia, 49% for surgeries and 44% for operating room time. In average, anesthesia took up 88% of the operating room period, and surgery, 61%. Conclusion This study identified patterns in the duration of surgery stages. The mean values of the specialties can assist with operating room planning and reduce delays.
