Periodontal diseases are immune inflammatory responses induced by dental plaque in which microorganisms harboured within a susceptible periodontium contributes to tissue destruction, bone loss and eventually tooth loss. The etiopathogenesis of periodontal disease is multifactorial which includes host associated factors, genetic factors, immune system dysfunction and environmental factors. Existing treatment modalities have resulted only in arresting the disease progression but have not cured the disease completely, nor do they avert the recurrence. Hence there is a need for therapeutic modalities which may include vaccines targeting periodontal pathogens. Vaccination is induction of immunity by injecting a dead or attenuated form of pathogen. Till date, no pre-emptive modality exists for periodontal disease, the availability of periodontal vaccine would prevent the progression of periodontal diseases. The aim of this review article is to confer the various approaches associated with periodontal vaccine.

The Coronavirus Disease (COVID), commonly known as “COVID-19 Pandemic” has affected around 218 countries and territories across the globe. Coronavirus is a deadly virus which gains entry into the human body through various modes and causes symptoms such as dry cough, fatigue, coughing sputum, shortness of breath. The doctors are among the various frontline workers, who are at the greatest risk of contracting the COVID-19 infection. One of the major modes of transmission of coronavirus is the oral cavity. Hence, oral health care workers are at higher risk. Periodontitis is one of the most prevalent chronic inflammatory diseases of the oral cavity and is associated with much common co-morbidity making it a community health concern. Periodontal procedures are aerosol generating procedures and COVID-19 is a highly contagious disease, so it can be easily contracted during aerosol generating procedures. Periodontitis and COVID-19 have both been associated with much common co-morbidity so there is a possible association between them. The role of periodontists in preventing transmission of COVID-19 is critically important. Periodontists face direct exposure to oral fluids such as saliva and blood. So, precautionary measures are imperative for the periodontists so as to protect ourselves. Knowledge about the virus would be helpful in taking the necessary precautions. The aim of this review article was to understand the risk associated with the coronavirus and protection for periodontists in an unprecedented situation.
