The Role of the Dental Surgeon in Controlling the Dissemination of COVID-19: A Literature Review

Table 1

The potential of SARS-CoV-2 transmission in a dental clinic and measures to prevent and control the infection in dental environments.

AuthorYearResearch, results, and conclusions

Kariwa et al. [14]2006(i) The use of several PVP-I (Povidone-Iodine) include disinfecting medical instruments and skin as well as hand-washing, gargling, and spraying the throat for coronavirus
(ii) The results clearly indicate that all the PVP-I products tested have strong virucidal activities against SARS-CoV
(iii) PVP-I products for gargling and spraying the throat may have a prophylactic effect on SARS during outbreaks

Segal and Wong [15]2008(i) Diagnosis through salivary tests is a remarkable process for the discovery of systemic diseases
(ii) The markers for obtaining diagnoses can be made in the dentist’s own office

Cleveland et al. [16]2016(i) Measures to prevent and control infections in dental environments must be applied to ensure the safety of patients and professionals, avoiding cross contamination

Ather et al. [17]2020(i) It is the duty of the dental surgeon to protect the population and provide quality care even in times of pandemic
(ii)The dental surgeon must not neglect the biosafety measures in their care. They can assist asymptomatic patients, but even they have a high power of viral transmission
(iii) Dental professionals are at a high risk of contamination and require more preventive care to avoid the transmission of COVID-19

Carroeul et al. [18]2020(i) The use of mouth rinses and/or nasal applications that contain β-cyclodextrins, combined with flavonoid agents, such as citrox, could provide valuable adjunctive treatment to reduce the viral load in saliva and nasopharyngeal microbiota, including potential SARS-CoV-2 carriage

Casamassimo et al. [19]2020(i) Even in the face of the pandemic, pediatric dentists used ethics to decide whether or not to put themselves at risk to treat the emergency needs of children and special patients
(ii) Even when performing all biosafety procedures, the risk of contamination is high. This pandemic raises several questions, as dentists are exposed daily to pathogens and infectious agents
(iii) The pandemic of COVID-19 accelerated the need for the integration of medicine and dentistry. These professionals were recognized for their role in a comprehensive system of care delivery and health behaviours

Coulthard [20]2020(i) The pandemic of COVID-19 challenged the entire healthcare system, and health professionals needed to act quickly to find ways to assist those who needed treatment during the pandemic

Chen et al. [1]2020(i) SARS-CoV-2 is a newly identified form of coronavirus with significant similarity to SARS-CoV
(ii) A structural analysis of the receptor binding domain (RBD) of spike glycoprotein responsible for the entry of coronaviruses into host cells through molecular simulation reveals highly similar ternary structures
(iii) ACE2 is an important receptor for COVID-19
(iv) Antibodies and small molecular inhibitors that can block the interaction of ACE2 with RBD should be developed to combat the virus

Dziedzic and Wojtyczka [21]2020(i) Dental professionals have several challenges in the future after the pandemic of COVID-19, as it is not yet known what oral changes may arise as side effects of the drugs used for treatment. Changes in soft tissues, xerostomia, candidiasis, ulcerations, and gingivitis are some of the possibilities that may occur after the cure of COVID-19

Li and Meng [22]2020(i) Dental professionals should be very careful when disposing of personal protection items to avoid cross contamination
(ii) It is necessary to perform examinations with great care, attempting to avoid or minimize nonurgent care during the pandemic
(iii) Asymptomatic patients can be sources of transmission of the virus during procedures due to the production of fluids and aerosols

Meng et al. [2]2020(i) Everyone should be aware of the risks of infection occurring in dental offices and schools
(ii) We must maintain the performance of prevention and control measures to avoid postepidemic infections

Peng et al. [4]2020(i) Dental professionals are at imminent risk due to the forms of transmission of COVID-19
(ii) Control and prevention measures against contamination require revising

Prati et al. [23]2020(i) Dental procedures have a high potential for contamination for professionals and students in clinical schools
(ii) Treatments, such as endodontics, which take longer to perform, tend to generate a high quantity of aerosols and oral fluids. Contact between the professional, student, and patient can cause cross contamination

Qu and Zhou [12]2020(i) Oral diseases due to psychological stress are indisputable
(ii) It is the role of the dental surgeon not only to treat the oral health of patients but also to guide and give psychological advice in order to improve the patient’s well-being

Sabino-Silva et al. [13]2020(i) Prevention measures are necessary for dental professionals due to the mode of viral transmission, occurring by inhalation of aerosols produced by dental procedures

To et al.' [24]2020(i) Examination of saliva samples detected coronavirus in 91.7% of patients
(ii) Saliva examination is promising and noninvasive

Xu et al. [25]2020(i) The expression of ACE2 in minor salivary glands was higher than that in the lungs, which suggests salivary glands could be a potential target for COVID-19
(ii) People with asymptomatic infections could disseminate the virus, as it can concentrate in the salivary glands
(iii) Saliva is considered a potential focus for the spread of SARS-CoV-2
