RESUMEN
Coronavirus infection is a transmissible disease. It was first described in China in December, 2019. It has been said to have a person-to-person transmission after prolonged and unprotected exposure. Patients with a potential SARS-CoV-2 exposure present with symptoms of low-grade pyrexia, dry cough, or shortness of breath. People with these symptoms should contact health-care providers before seeking medical intervention so that appropriate preventive actions may be implemented. Health-care facilities should rapidly isolate suspected individuals and notify local health departments for support involved in performing laboratory tests and efforts in containment. The present article describes the nature of virus, method of detection, and its mode of transmission.
RESUMEN
BACKGROUND: The aim of endodontic and restorative dentistry is the conservation of natural tooth structure. Endodontically treated tooth (ETT) undergoes loss of tooth structure and changes in physical characteristics. Therefore, proper selection of restoration for ETT is mandatory. The clinical approach of restoring ETT needs taking into considerations several issues. However, the best way to restore teeth after root canal treatment has long been and still a controversial subject to debate. Therefore, this study was carried out to detect the frequency of preferred methods of restoring ETT under different conditions. MATERIALS AND METHODS: A questionnaire was framed and distributed among prosthodontists, endodontist and general practitioners of north India region to find out the frequency of best suitable material and method regarding restoration of ETT. 220 questionnaires were sent by electronic mail out of which 110 were received back. The questionnaire contained different methods of restoration of endodontically treated anterior teeth at different conditions (percentages) of remaining sound tooth structure. Respondents were asked to indicate their preferred method of restoration of those teeth. RESULTS: Results showed that majority of respondents (51.82%) preferred to restore the tooth only with a tooth-color restorative material in condition A. In condition B, majority of respondents preferred to use tooth colored crown (44.55%) and prefabricated post and tooth colored restoration (24.5%). Whereas in condition C, most of the respondents preferred to use a cast post and core/crown (80.91%). CONCLUSION: From the findings of the present study, it can be concluded that the unrestored ETT is susceptible to fracture, which could lead to loss of tooth and that the maximum preservation of healthy tooth structure and use of restorative materials with mechanical properties similar to dental structure favor greater longevity of tooth restoration complex.
RESUMEN
UNLABELLED: HISTORY AND OBJECTIVE: The aim of this study was to study the anxiolytic effects of Ocimum sanctum stress-induced anxiety. MATERIALS AND METHODS: The study was carried out using male albino rats (200 ± 50 gm), male albino mice (25 ± 100) the effect of O. sanctum evaluated for anxiety and depression using forced swim test FST and rotarod test. RESULTS: Restraint stress (3 hours/day for six consecutive days) induced a significant reduction. It was significantly decreases the mobility period during stress. The standard deviation values are 14.4 and 9.26 and is statistically significant (p = 0.001). In rotarod test, (a) increased latency and (b) decreased ambulation and rearing were also reversed by O. sanctum. A significant increase in immobility period was observed in FST and TST after restraint stress. O. sanctum and C. sinensis significantly reduced the immobility times of rats in FST and TST. CONCLUSION: Ocimum sanctum possess significant antistress activity but the magnitude and efficacy for relieving stress is less, when compare to standard anxiolytic agent, i.e. Alprazolam.
