Introduction: Traumatic dental injury usually causes injury to hard dental tissue, periodontal tissue and dental pulp. Intrusion is the apical displacement of the tooth towards the alveolar bone making it susceptible to infection and fracture.
Case Report: This report conveys intrusion management of a right maxillary central incisor of a ten-year old boy referred to Isfahan Dental School with dental trauma, with a follow-up of six, twelve and eighteen-months showing evidence of healing.
Background. Avulsion is among the most severe types of dental trauma, which often occurs at young ages and can compromise the long-term prognosis of the traumatized tooth. Case Report. Herein, we report replantation of two avulsed teeth. Our patient was an 11-year-old boy with two avulsed maxillary central incisors due to a bicycle fall 2 months earlier. The patient was referred to us after rigid splinting of his teeth by a surgeon. Long-term calcium hydroxide (CH) therapy was performed for the patient, and after healing of periodontal ligament (PDL), apexification was performed for both teeth followed by root canal therapy. During the 2-year follow-up, both teeth were functional and had no radiographic or clinical evidence of resorption or ankylosis. Conclusion. The reported case highlights the favorably high tissue healing potential following severe dental trauma, given that appropriate treatment is performed. Correct endodontic management can guarantee the long-term prognosis of teeth following severe dental trauma.
Introduction: Apexification is a method to create a calcification barrier in teeth with open apex and pulp necrosis. For many years, calcium hydroxide was the most common substance for this purpose. Nowadays, apexification with other materials that can yield better results in one session has become more popular.
Case report: For a 9-year-old boy complained of “tooth decay”, apexification treatment was performed by MTA on the lower right sixth permanent molar and by cold ceramic on the lower left sixth permanent molar. At one-year follow-up, no symptoms were observed on clinical examination and radiography of both teeth.
Conclusion: Cold ceramic such as MTA can be considered effective in the apexification of immature tooth with pulp necrosis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
