Methods
A protocol specific for the objectives of this study was developed according to the criteria for a scoping review. Relevant databases (Pubmed, Scopus, Elsevier, Science Direct, Wiley), including online access to health/ dental organizations (World Health Organization/ American Dental Association), were searched to identify evidence which was restricted to the English language for the period 2015-2020. Predetermined eligibility criteria were applied, evidence was assessed and data extracted for each included article. Relevant outcomes assessed were: infection control measures, transmission of the SARS-CoV-2 virus, such as modes and sources of transmission and the ethical principles related to the dental setting with a focus on the COVID-19 pandemic.
Results
Searches yielded a total of 402 articles: 387 from electronic databases and 15 from other sources. Of these, 231 were unrelated to the objectives of the current scoping review. The full text of 69 studies was assessed for eligibility, of which 26 were finalized for inclusion following the objectives and inclusion criteria set for the scoping review. Most of the included articles were reviews, recommendations and guidelines for dentists. A narrative explanation of the pre-specified outcomes is reported for the 3 areas covered for this review. There is no clinical evidence available that can support the recommendations by individuals, dental organizations or health authorities related to the objectives of this review, but these may be considered as the much needed guidelines during the unprecedented COVID-19 pandemic. A different ethical framework is required during a pandemic and these must be informed by evidence.
