    Background Further understanding of the distribution and changing characteristics of dental diseases is of great significance for all dental emergency centers for strengthening the medical staff’s treatment abilities and effective use of emergency resources in the face of public health emergencies involving highly infectious respiratory diseases MESHD.Methods The medical records of 4158 cases of dental emergency patients from 2019 to 2020 were retrospectively analyzed, with patients divided into the pre-SARS-COV-2 group and the SARS-COV-2 group, according to the date of their admission to the dental emergency center. The dental emergency patients’ demographic data, date and time, diagnoses, and treatment approaches were compared before and during the SARS-COV-2 pandemic.Results During the SARS-COV-2 pandemic, the number of dental emergency visits increased by 29.7%. The peak of the number of patients at weekends and at night is not obvious compared with the pre-SARS-COV-2 group. During the pandemic, males (n=286, 58.1%) were more likely to visit dental emergency centers for trauma MESHD than females (n=206, 41.9%) (P<0.05); females (n=242, 60.8%) were more likely to visit dental emergency centers for acute gingivitis MESHD and acute pericoronitis MESHD than males (n=156, 39.2%) (P<0.05). A major change in diagnosis was related to acute pulpitis MESHD (K04.0) and acute apical periodontitis MESHD (K04.4), which increased by 9.2%; acute gingivitis MESHD (K05.0) and acute pericoronitis MESHD (K05.2) increased by 3.5%; open wound of the lip MESHD and oral cavity (S01.5) decreased by 17.9%; other conditions (non-emergency diseases) increased by 6.8%, compared with the pre-SARS-COV-2 period. Among the treatment modalities, during the pre-SARS-COV-2 period, 304 patients (17.7%) received a prescription for antibiotics and analgesics, and 1485 (86.5%) received a prescription for local treatment. During the SARS-COV-2 period, 958 (39.2%) received a prescription for antibiotics and analgesics, and 1636 (67.0%) received a prescription for local treatment.Conclusion SARS-COV-2 pandemic led to changes in the characteristics of dental emergency patients. Trauma MESHD, acute pulpitis MESHD, and acute periodontitis MESHD are the leading reasons patients refer to dental emergency centers. Dental emergency centers should optimize treatment procedures, optimize the staff, and reasonably allocate materials according to the changes to improve the on-site treatment capacity and provide adequate dental emergency care.
