The entire planet is suffering from the current infection- COVID-19 and it has not only caused a depression in economy but had put every individual at a risk of catching the virus, especially the medical and dental health professionals who are in direct contact with the patients. As on 22 September, 2020 there are 34.1 million cases recorded for COVID-19, of which 21.5 million people recovered from the infection and sadly, 9.66 lakhs population died of COVID-19 infection. This does not make us forget the 2009 Swine flu pandemic that had infected 60 million population world-wide. The H1N1 virus was a new swine flu virus that had genetic material of swine, bird and human influenza virus in combination due to reassortment whereas SARS-CoV-2 is very similar to the SARS-CoV that happened in 2002-2003, indicating that a new person-to-person transmission of infectious agent (coronavirus) had caused the outbreak of the COVID-19 pandemic. In India, day by day the graph of COVID-19 infection is rising. So, it is important to take into consideration about both the pandemics as it may prove to be a deadly one.

The aim of our review is to give a complete picture of a rare condition such as the osteosarcoma of the jaw. Through the analysis of various case reports and retrospective cohort studies, the research in the literature about this topic allowed us to highlight its epidemiological, physiological, diagnostic and therapeutic aspects. In particular we tried to give greater emphasis to the X-ray aspects and diagnostic evidence of the pathology. At the epidemiological level, the osteosarcoma is a type of cancer that affects particularly young people, and for this reason most cases examined are distributed to individuals between 10 and 30 years, but we have not included exclusion criteria for this aspect. The research focused on the collection and analysis of case reports and retrospective studies from the newest to the oldest ones, as there are no substantial differences in the approach. Osteosarcomas (OS) of all sites represent 40% to 60% of primary malignant bone cancers. About 10% of osteosarcomas occur in the head and neck; most of them are in the mandible or in the maxilla. The JOS (Osteosarcoma of the jaws) represents 6-7% of all primary osteosarcomas. The mandible is more commonly involved than the maxilla (from 1.5:1 to 2:13). In many cases there is an association with smoking, alcohol and pathologies such as Paget's disease, Li-Fraumeni syndrome, Sjogren's syndrome, bone diseases, treatment with chemotherapy and radiotherapy. Symptoms and signs most frequently reported by patients are swelling, loss of dental stability, pain, ulceration of mucosa, hypoesthesia and parestesia. At the X-ray level, diagnostic techniques such as orthopantomography are preferred, identifying radio-light or radio-opaque lesions, and periapic endoral x- rays, in which the presence of the enlarged periodontal ligament, the so-called Garrington sign and the "sunbeam" appearance, are highlighted. The use of CT and Magnetic resonance imaging has allowed better detection of the lesion in ....

Rare diseases have a prevalence that is not more than 5 cases per 10,000 people. Some rare diseases have oral manifestations. Among these conditions, there are some syndromes, such as Gorlin Goltz, Turner syndrome, SAPHO, Williams syndrome, Schimke Immuno, Cherubism, and Neurofibromatosis type 1. Considering their low incidence and high complexity, these disorders require a diagnostic and therapeutic approach based on the interaction of several specialists. In these field, the dentist plays a leading role: he is at the forefront of the early detection of diseases whose prodromal signs may forerun systemic manifestations by few years. Orthopantomography (OPT) allows to identify changes in bone structures and dental anomalies of shape and number, often associated with the above listed manifestations. The aim of this article is to show how the dentist, basing on some radiological evidences, may be able to make an early diagnosis or to formulate a diagnostic hypothesis that will need to be approved by a multidisciplinary team.
