The aim of this update is to summarize the up-to-date knowledge about the virus, its way of transmission, clinical features, diagnosis, and treatment. Result: The COVID-19 is a public health threat affecting humankind currently after the emergence and spread of the novel coronavirus or the severe acute respiratory syndrome coronavirus 2. The virus is believed to have originated from bats and transmitted to humans. Around 1.5 million peoples are confirmed to have the COVID-19 and more than 83000 individuals have died of it by April 8, 2020, all over the world. It is transmitted by inhaling or having contact with droplets. The incubation period ranges from 2-14 days. It manifests mainly with fever, non-productive cough, and dyspnea. The polymerase chain reaction from various samples like throat swabs, nasal swabs, bronchoalveolar lavage fluid is used to confirm the diagnosis. High-resolution chest computerized tomography is abnormal in most patients, and typical findings are ground glass patchy opacities on both lungs and sub-segmental consolidation. Treatment is largely supportive. However, trials are ongoing, and chloroquine and hydroxychloroquine have got a lot of attention in the battle against COVID-19. Oumer A.

In addition to lung damage, Bourneville’s tuberous sclerosis (BTS) also affects the skin, brain, retina, kidneys, and, less frequently, the heart and bone. We report the case of a young patient with bilateral pneumothorax revealing pulmonary lymphangiomyomatosis in the context of Bourneville’stuberoussclerosis BTS.

Pulpectomy is indicated in primary teeth with carious pulp exposures in which coronal and radicular pulp exhibits clinical signs of hyperemia or evidence of pulp necrosis with or without caries involvement. In primary teeth, it can be challenging and time-consuming, especially during canal preparation, which is considered one of the most important steps in root canal therapy. The development of NiTi rotary files has helped pediatric dentists also. With the availability of rapidly coming versions of these files, it may be difficult to pick appropriate file systems and techniques most suitable for an individual case. Practitioners must always bear in mind that all file systems have benefits and weaknesses.
