Internal root resorption has been described as a resorptive defect of the internal aspect of the root following necrosis of odontoblasts as a result of chronic inflammation and bacterial invasion of the pulp tissue. Successful treatment outcome depends on early diagnosis, removal of the cause, proper treatment of the resorbed root. The present case report demonstrates the use of biodentine for the management of internal resorption.he aim of this study was to evaluate the efficacy of different lengths of time of passive ultrasonic irrigation (PUI) in removing calcium hydroxide (CH) paste from root canal, using scanning electron microscopy and energy dispersive spectrometry (SEM/EDS).
