Description: There is lack of data on whether the coronavirus disease 2019 (COVID-19) pandemic was associated with changes in the etiology of pathosis in endodontic patients. The aim of this study was to determine the rate of cracks and other etiologic factors during the period of March 16th to May 31st in 2020 (COVID-19 initial outbreak) and 2021 (COVID-19 ongoing pandemic) compared with figures from the same period in 2019 (pre-COVID era) in 2 endodontists’ practices.

At the conclusion of this article, the reader will be able to: 

  • Identify the important etiologic factors for endodontic treatment in Endodontists’ offices
  • Determine the rate of cracked teeth before and after the onset of the pandemic
  • Determine the rate of persistent infections before and after the onset of the pandemic
