This emerging pandemic and its severe outbreak in the Italian population have induced the Italian Government first and then the European Union to promote drastic impact measures to “flatten the curve” of the COVID-19 infection and in turn avoid health systems (in particular, intensive care units) being overwhelmed, resulting in fewer deaths [1]. The limitation of people circulating outside their home, social distancing, the cessation of almost all working activities and the request to the population to use protective masks and gloves all have the aim of minimizing the likelihood that people who are not infected come into contact with others who are already infected and probably still asymptomatic [2]. As always happens, healthcare professionals have been immediately involved in the national emergency, working hard, often day and night: unfortunately, small numbers of them have also become infected, and some have tragically died. Dentists are often the first line of diagnosis, as they work in close contact with patients. On 15 March 2020, the New York Times published an article entitled “The Workers Who Face the Greatest Coronavirus Risk”, where an impressive schematic figure described that dentists are the workers most exposed to the risk of being affected by COVID-19, much more than nurses and general physicians [3]. To take significant actions against this harmful disease, the American Dental Association updated its webpage in March, including a link to frequently asked questions from member dentists covering topics such as personal protective equipment and patient communications. Recently, an interesting paper written by researchers from Wuhan University School and Hospital of Stomatology was published with several recommendations for dentists and dental students to manage COVID-19 patients [4]. Dentists have been recommended to take several personal protection measures and avoid or minimize operations that can produce droplets or aerosols; moreover, the use of saliva ejectors with a low volume or high volume can reduce the production of droplets and aerosols. Taking into consideration the severity of the pandemic COVID-19, and in the light of the massive commitment of several dental associations and the most prestigious dental journals, it is essential to give clear and easy guidelines to manage dental patients and to make working dentists safe from any risk. A fundamental concept is that the transmission of the virus is mainly through inhalation/ingestion/direct mucous contact with saliva droplets; it is also critical to remember that the virus can survive on hands, objects or surfaces that were exposed to infected saliva in the previous nine days [4,5]. Since the viral load contained in the human saliva is very high, rinses with antiseptic mouthwashes can only reduce the infectious amount but are not able to eliminate the virus in the saliva [4,5]. In this light, a few important concepts would be useful to briefly report and discuss here.","tracks":[{"project":"LitCovid-PubTator","denotations":[{"id":"52","span":{"begin":183,"end":191},"obj":"Species"},{"id":"53","span":{"begin":559,"end":565},"obj":"Species"},{"id":"54","span":{"begin":784,"end":790},"obj":"Species"},{"id":"55","span":{"begin":1219,"end":1227},"obj":"Species"},{"id":"56","span":{"begin":1331,"end":1342},"obj":"Species"},{"id":"57","span":{"begin":1779,"end":1786},"obj":"Species"},{"id":"58","span":{"begin":2009,"end":2017},"obj":"Species"},{"id":"59","span":{"begin":2541,"end":2549},"obj":"Species"},{"id":"60","span":{"begin":2939,"end":2944},"obj":"Species"},{"id":"61","span":{"begin":174,"end":182},"obj":"Disease"},{"id":"62","span":{"begin":401,"end":409},"obj":"Disease"},{"id":"63","span":{"begin":410,"end":419},"obj":"Disease"},{"id":"64","span":{"begin":529,"end":535},"obj":"Disease"},{"id":"65","span":{"begin":803,"end":811},"obj":"Disease"},{"id":"66","span":{"begin":858,"end":866},"obj":"Disease"},{"id":"67","span":{"begin":1095,"end":1103},"obj":"Disease"},{"id":"68","span":{"begin":1473,"end":1481},"obj":"Disease"},{"id":"69","span":{"begin":2000,"end":2008},"obj":"Disease"},{"id":"70","span":{"begin":2348,"end":2356},"obj":"Disease"},{"id":"71","span":{"begin":2852,"end":2867},"obj":"Disease"}],"attributes":[{"id":"A52","pred":"tao:has_database_id","subj":"52","obj":"Tax:9606"},{"id":"A53","pred":"tao:has_database_id","subj":"53","obj":"Tax:9606"},{"id":"A54","pred":"tao:has_database_id","subj":"54","obj":"Tax:9606"},{"id":"A55","pred":"tao:has_database_id","subj":"55","obj":"Tax:9606"},{"id":"A56","pred":"tao:has_database_id","subj":"56","obj":"Tax:11118"},{"id":"A57","pred":"tao:has_database_id","subj":"57","obj":"Tax:9606"},{"id":"A58","pred":"tao:has_database_id","subj":"58","obj":"Tax:9606"},{"id":"A59","pred":"tao:has_database_id","subj":"59","obj":"Tax:9606"},{"id":"A60","pred":"tao:has_database_id","subj":"60","obj":"Tax:9606"},{"id":"A61","pred":"tao:has_database_id","subj":"61","obj":"MESH:D007239"},{"id":"A62","pred":"tao:has_database_id","subj":"62","obj":"MESH:C000657245"},{"id":"A63","pred":"tao:has_database_id","subj":"63","obj":"MESH:D007239"},{"id":"A64","pred":"tao:has_database_id","subj":"64","obj":"MESH:D003643"},{"id":"A65","pred":"tao:has_database_id","subj":"65","obj":"MESH:D007239"},{"id":"A66","pred":"tao:has_database_id","subj":"66","obj":"MESH:D007239"},{"id":"A67","pred":"tao:has_database_id","subj":"67","obj":"MESH:D007239"},{"id":"A68","pred":"tao:has_database_id","subj":"68","obj":"MESH:C000657245"},{"id":"A69","pred":"tao:has_database_id","subj":"69","obj":"MESH:C000657245"},{"id":"A70","pred":"tao:has_database_id","subj":"70","obj":"MESH:C000657245"},{"id":"A71","pred":"tao:has_database_id","subj":"71","obj":"MESH:D007239"},{"subj":"52","pred":"source","obj":"LitCovid-PubTator"},{"subj":"53","pred":"source","obj":"LitCovid-PubTator"},{"subj":"54","pred":"source","obj":"LitCovid-PubTator"},{"subj":"55","pred":"source","obj":"LitCovid-PubTator"},{"subj":"56","pred":"source","obj":"LitCovid-PubTator"},{"subj":"57","pred":"source","obj":"LitCovid-PubTator"},{"subj":"58","pred":"source","obj":"LitCovid-PubTator"},{"subj":"59","pred":"source","obj":"LitCovid-PubTator"},{"subj":"60","pred":"source","obj":"LitCovid-PubTator"},{"subj":"61","pred":"source","obj":"LitCovid-PubTator"},{"subj":"62","pred":"source","obj":"LitCovid-PubTator"},{"subj":"63","pred":"source","obj":"LitCovid-PubTator"},{"subj":"64","pred":"source","obj":"LitCovid-PubTator"},{"subj":"65","pred":"source","obj":"LitCovid-PubTator"},{"subj":"66","pred":"source","obj":"LitCovid-PubTator"},{"subj":"67","pred":"source","obj":"LitCovid-PubTator"},{"subj":"68","pred":"source","obj":"LitCovid-PubTator"},{"subj":"69","pred":"source","obj":"LitCovid-PubTator"},{"subj":"70","pred":"source","obj":"LitCovid-PubTator"},{"subj":"71","pred":"source","obj":"LitCovid-PubTator"}],"namespaces":[{"prefix":"Tax","uri":"https://www.ncbi.nlm.nih.gov/taxonomy/"},{"prefix":"MESH","uri":"https://id.nlm.nih.gov/mesh/"},{"prefix":"Gene","uri":"https://www.ncbi.nlm.nih.gov/gene/"},{"prefix":"CVCL","uri":"https://web.expasy.org/cellosaurus/CVCL_"}]},{"project":"LitCovid-PD-FMA-UBERON","denotations":[{"id":"T1","span":{"begin":13,"end":17},"obj":"Body_part"},{"id":"T2","span":{"begin":1313,"end":1317},"obj":"Body_part"},{"id":"T3","span":{"begin":2192,"end":2198},"obj":"Body_part"},{"id":"T4","span":{"begin":2725,"end":2731},"obj":"Body_part"},{"id":"T5","span":{"begin":2861,"end":2867},"obj":"Body_part"},{"id":"T6","span":{"begin":2945,"end":2951},"obj":"Body_part"},{"id":"T7","span":{"begin":3086,"end":3092},"obj":"Body_part"}],"attributes":[{"id":"A1","pred":"fma_id","subj":"T1","obj":"http://purl.org/sig/ont/fma/fma9712"},{"id":"A2","pred":"fma_id","subj":"T2","obj":"http://purl.org/sig/ont/fma/fma24728"},{"id":"A3","pred":"fma_id","subj":"T3","obj":"http://purl.org/sig/ont/fma/fma59862"},{"id":"A4","pred":"fma_id","subj":"T4","obj":"http://purl.org/sig/ont/fma/fma59862"},{"id":"A5","pred"
