Abstract: Objective: To summarize the clinical features and therapeutic experience of Henoch Schonlein purpura in children with toothache as the first symptom. Methods: Clinical data of 10 cases acute periapical periodontitis complicated by Henoch Schonlein purpura in children were analyzed in Affiliated Stomatological Hospital of Zunyi Medical College from January 2010 to June 2015. Results: Ten patients all received dental treatment. Among them 9 cases were hospitalized once and cured, while 1 case was hospitalized twice because of the periapical periodontitis in the remaining teeth. Conclusion: As the first symptom of HSP, toothache can lead to the misdiagnosis which usually fails to cause the vigilance of the Department of Stomatology or pediatricians. Therefore, solid basic skills in clinic and strengthened discipline cooperation are conducive to early detection and treatment of HSP.
