Idiopathic internal resorption in primary canines and molars- Case report

Background: We report a case of idiopathic internal resorption in primary canines and molars.Case Presentation: A Japanese boy aged 4 years 0 months with no history of orofacial trauma was referred for a fracture in the crown of the maxillary right primary canine with exposed pulp. Internal resorption was diagnosed, and pulp treatment was performed to preserve the tooth from further resorption. Consequently, internal resorption was found in five primary teeth within 18 months during follow-up appointments.Conclusion: In patients with idiopathic internal resorption seen in multiple primary teeth, short-term follow-up examinations and treatment for tooth preservation should be performed.(c) 2022 Japanese Society of Pediatric Dentistry.
