“…Due to the high risk of SARS-COV-2 transmissions via dental emergency treatments,the use of therapeutic instruments and equipment has been limited,such as high speed turbines used in pulp treatment,periodontal irrigation for the patientand.The selection of emergency treatment programs was also affected according to the change of the SARS-COV-2 situation.The selection of treatment instruments and equipment was mainly for the treatment of acute symptoms,and the principles of diagnosis and treatment during the SARS-COV-2 are mainly to relieve pain,eliminate in ammation, hemostasis,debridement and suture.In cases of acute Pulpitis (K04.0) and acute apical periodontitis (K04.4),the emergency treatments performed were pulp drainage,or dental pulp inactivation and pulpectomy,hence,these treatment measures as well as medullary pulp cavity disinfection and operation for pain treatments appeared to have increased during the SARS-COV-2.Acute pericoronitis(K05.2) mainly occurs in young people aged 18 to 30 years old [26].During an infection, tooth extraction may lead to the spread of infection and at the same time increases the risk of infection with SARS-COV-2.Therefore,the treatment of acute pericoronitis should be a local treatment,supplemented by Antibiotics and Analgesics drug therapy.For abscess,a small incision is needed for pus discharge and in case of space infection,systemic anti-in ammatory treatment may be necessary [27].The present study showed that trauma accounted for 20.1% during the SARS-COV-2 and although it had decreased from before the SARS-COV-2,it was still the main dental emergency among minors during the SARS-COV-2.Previous studies have shown that children are more likely to suffer trauma [15,28],Parents with children in emergency rooms are more anxious because of SARS-COV-2 [29],Therefore,dentists in charge of dental emergency rooms should be familiar with dental trauma in the primary and mixed dentition.In particular, behavior control is di cult in terms of children with trauma and since guardians can be sensitive and anxious,dentists should be well-trained for the behavioral control of the patient and guardian,their prognosis, and follow-up measures. If necessary,knowledge of drugs and emergency treatment is alsorequired,as pediatric patients may need to be sedated through medication [20,30].During the SARS-COV-2,the emergency treatment principle of trauma was to check the patient's overall condition,whether there was any injury to the brain,chest,abdomen and important organs and to conduct surgical suturing of the injury after excluding any life-threatening conditions [31].…”
