Pediatric maxillofacial infections during COVID-19, what have we learned?

Abstract

BackgroundThe COVID-19 pandemic significantly affected healthcare systems worldwide, and the field of dentistry is no exception. Odontogenic infections in pediatric patients pose unique challenges to treatment and diagnosis. PurposeThe purpose of this study was to evaluate the incidence, characteristics, and treatment of pediatric maxillofacial odontogenic infections during COVID-19 compared to pre-COVID-19. Study design, setting, and sampleThis retrospective cohort study included all pediatric patients (0-18 years) who visited the emergency department (ED) at Tzafon Medical Center, Israel, between March 2020 and February 2021 (COVID-19), or between March 2018 and February 2020 (Pre-COVID-19), and were diagnosed with maxillofacial odontogenic infections. Patients with missing demographic data and patients who did not complete the medical examination were excluded. Predictor/exposure/independent variableThe exposure variable was the date of presentation, categorized as COVID-19 or pre-COVID-19. Main outcome variable(s)The main outcome variables were the proportion of patients diagnosed with odontogenic infections, hospitalization rate, treatment methods, and length of hospital stay (LOS). CovariatesCovariates included patient demographics, involved dentition and associated spaces, and the administration of antibiotics before ED arrival. AnalysesFisher exact test and Pearson's chi-squared test were applied to assess differences in categorical variables. Wilcoxon rank-sum test was used for independent variables. A logistic regression model was used to predict outcome variables. P-values were two-tailed and statistical significance was defined as p<0.05. ResultsThe study sample comprised 471 patients: 357 (76%) in the pre-COVID-19 period and 114 (24%) during COVID-19. The relative-risk of visits to the ED out of total oral and maxillofacial ED visits was lower during COVID-19 (RR=0.65, p=0.0001). The hospitalization rate increased from 72% (257 patients) pre-COVID-19 to 86.8% (99 patients) during the COVID-19 period (p=0.001). LOS during Covid-19 was significantly shorter than pre-COVID-19 (p<0.001). ConclusionsThe findings of this study reveal a significant reduction in odontogenic infection incidents referred to the ED during the pandemic. This implies that many of these incidents can be successfully treated in community healthcare settings, without referral to the ED.
