Abstract：AIM:To obtain the cognition of general dentists in comprehensive hospitals regarding the diagnosis and treatment of avulsed permanent teeth through questionnaire surveys,thereby providing a scientific basis for standardizing the treatment of avulsed permanent teeth.METHODS:General dentists from five comprehensive hospitals were selected as the research subjects.Questionnaires were distributed via Wenjuanxing platform to explore their knowledge about the definition,epidemiology,treatment principles,and prognostic factors of avulsed permanent teeth.RESULTS:A total of 89 valid questionnaires were collected.The results showed that 87.64％of general dentists knew the definition of avulsed permanent teeth,but only about half consider it to be clinically common.77.53％of general dentists believed that maintaining the vitality of periodontal ligament prior to replantation is of crucial significance for the prognosis.However,their knowledge about root surface treatment before replantation,fixation methods after teeth replantation,and the choice of storage media was inadequate.Approximately 63％of the dentists encounter patients with permanent teeth avulsion each year.The majority thought that replantation time,storage conditions for teeth,patient age,root development stage,and oral hygiene status were critical factors influencing prognosis.However,the timing of the first review after replantation was poorly understood.CONCLUSION:Although general dentists in comprehensive hospitals have a basic knowledge about avulsed permanent teeth,they need further training about treatment principles,prognostic factors,and postoperative management.This will promote the attention on permanent teeth avulsion,and improve the long-term prognosis after dental replantation.
