      Introduction: The first outbreak of coronavirus disease 2019 (COVID-19) in the United States resulted in nationwide closure of dental offices that created an oral health crisis. The aim of this observational study was to analyze and compare the characteristics of patients who visited two private Endodontics offices from March-16 to May-31, 2020, compared to the same period in 2019. Methods: Demographic, diagnostic, and procedural data of 1520 (693 in 2020; 827 in 2019) patient visits were collected. Bivariate and multiple logistic regression analyses were used to assess the impact of COVID-19 outbreak on patient-related variables. Results: Bivariate analyses showed that the number of patient visits decreased in April and May 2020 (P<.0001). In 2020, patients' self-reported pain level was higher, they were more frequently diagnosed with pulp necrosis, and acute apical abscess, and they received more incisions for drainage (P<.05). Multiple logistic regression analyses showed that COVID-19 outbreak was associated with less visits for patients older in age (> 49.5 years) (odds ratio [OR], 0.720; 95% confidence interval [CI], 0.573-0.906), more patients with kidney diseases (OR, 2.690; 95% CI, 1.143-6.331), higher levels of pain on percussion (OR, 2.277; 95% CI, 1.718-3.016), less cases with previously initiated treatment (OR, 0.242; 95% CI, 0.080-0.731), less periapical diagnosis of asymptomatic apical periodontitis (OR, 0.510; 95% CI, 0.306-0.849), higher number of non-surgical root canal treatments (OR, 2.073; 95% CI, 1.397-3.074) and apicoectomies (OR, 2.799; 95% CI, 1.367-5.729). Conclusion: These findings show that the public health burden of endodontic infections was more intense during the initial outbreak of COVID-19.
