Drawing on multiple sources, this article presents an analysis of a national survey implemented by Street Clinic teams in Brazil on the homeless population and the COVID-19 pandemic. Through the lens of certain ethical-political principles and methodological decisions, we focus our analysis on discourses about who lives and works on the streets during the pandemic, connecting discourse with experience. From the perspective of governmentality and biopolitics, we seek to shed light on power relations that reveal modes of government embodied at the street level – mainly related to isolation measures and social distancing – to create tensions surrounding the emergence of the notion of the homeless population in the midst of the pandemic. We conclude with a discussion of the precariousness that circumscribes life on the streets as a shared condition, and search for ways to comprehend forms of resistance and the right to exist.Based on ethnographic work with undocumented immigrant women who developed depressive episodes due to various forms of violence, this article recovers the women’s experience of care in the clinic space of their host country. Through therapeutic itineraries of care, the article focuses on the case studies of two women of Mexican origin in New York City to describe, based on their experience, the communication and the encounter between the doctor and patient; the expectations of migrant women regarding mental health care services; and the explanatory models of depression of both the patients and the treating physicians. This analysis seeks to contribute to the knowledge regarding ways of treating the mental health problems of undocumented women in contexts of violence.All-ceramic dental implants have been identified as a potential alternative to the traditional titanium-based implant systems used in dentistry to satisfy the demands for esthetic metal-free treatment of edentulous jaws. Among the all-ceramic implants introduced in dentistry, zirconia implants have emerged as the forerunner. The success of zirconia as an implant material has paralleled that of titanium in the short-term, however, few clinical studies assess success in the long-term. Failures of zirconia dental implants have been linked to improper operator techniques, manufacturing defects, and unfavorable loading, thereby necessitating optimal quality control measures by manufacturers and proper treatment planning by an experienced operator to reinforce the favorable properties of zirconia as an implant biomaterial. In this comprehensive review, the various implant-related, tissue-related, prosthesis-related, and patient-related factors affecting the success of zirconia implants have been discussed and compared with those of the titanium implant.Full-mouth rehabilitation is the restoration of the form and function of the masticatory apparatus. Complete dentistry has five comprehensive goals in full-mouth rehabilitation anatomic harmony, optimal oral health, best aesthetics, occlusal stability, and functional harmony. Oral health-related quality of life (OHRQoL) has become an important issue in the clinical practice of dentistry. Loss of complete natural teeth and resorption of alveolar bone are considered oral health impairment because they hinder the mastication, phonetics, and aesthetics of the stomatognathic system. A questionnaire was prepared regarding the oral health-related quality of life of implant-supported full-mouth rehabilitation patients, using 2,637 patient records first identified and analyzed according to specific inclusion criteria. Patients who did not fulfill the criteria were not included. Seven patient records were finalized and a telephonic conversation was held to administer the questionnaire. The results obtained were first categorized and analyzed via SPSS as follows age 46-60 years; gender males (57.1%), females (42.9%); difficulties in food chewing yes (28.6%), no (57.1%), sometimes (14.3%); crown fitting yes (14.3%), no (85.7%); pain in tissue while masticating sometimes (14.3%), never (85.7%); self-conscious yes (57.1%), no (71.4%); changes from natural tooth yes (28.6%), no (71.4%); difficulties compared with natural teeth chewing difficult (14.3%), pain (14.3%), no difficulties (71.4%). Within the limits of the study, it was seen that patients with implant-supported full-mouth rehabilitation have improved appearance, better satisfaction, and higher quality of life.The term peri-implantitis describes an inflammatory disease that results in the loss of supporting bone around an implant. It differs from mucositis in which the inflammation of mucosa surrounding an implant is not accompanied by bone loss and is reversible. Peri-implant diseases are not uncommon following implant therapy. This study aims to find the incidence of peri-implantitis and peri-implant mucositis among patients having undergone implant therapy in dental university hospital in Chennai, India. A retrospective cross-sectional study was conducted using 305 samples from the Department of Implantology after reviewing and analyzing the data of 86,000 patients between June 2019 and March 2020. Microsoft Excel® was used to tabulate the data obtained. The variables assessed were age, gender, presence of infection, type of inflammation, and site of implant placement. The sample had a gender distribution of 60.33% males and 39.67% females. Forty-one percent of implant patients belonged to the age group of 36-55 years. The most (27.5%) common site of implant placement was sextant 4 specifically in relation to the first molar; 98.69% of implant sites showed no signs of infection; 0.66% of implants (in one subject) showed peri-implantitis; 0.33% showed peri-implant mucositis; and for 0.33% of implants the data was insufficient for categorization. Within the limits of the study, the incidence of peri-implantitis and peri-implant mucositis was 1.31% among implant patients of a dental university hospital in Chennai, India.It is essential to assess bone density among mandible teeth as well as among patients and also to observe the variation in all mechanical parameters of the bone for accurate design of patient-specific dental implants. This information helps in the design of implants to create a more osseointegration-friendly environment at the bone adjacent to the implant. selleck chemical For this study, 40 patients were chosen irrespective of age, sex, and bone density. Hounsfield Units were calculated using cone beam computed tomography data. Seven teeth were studied central incisor, lateral incisor, canine, first premolar, second premolar, first molar, and second molar. A total of 12 arbitrary points were chosen in both buccal and lingual sides which were further divided into external and internal. From the analysis, it was observed that the bone density of the central incisor and that of the canine is greater than that of the molars.
