Aim: To assess the effectiveness of calcium-enriched mixture (CEM cement) to decelerate replacement resorption in replanted teeth.
Background: A high prevalence of traumatic injuries in the orofacial region have been reported in school children. External replacement resorption (ERR) is the most common complication of replanting an avulsed tooth. Ankylosed teeth were lost in the first few years after ERR was initiated in young patients. Fixed replacement using dental implants or bridges is best delayed until skeletal growth is completed in young patients. With the gamut of biosilicate cements available, operators can now attempt to salvage these young permanent teeth diagnosed with ERR until the age when skeletal growth is complete.
Case description: In this case report, a novel biosilicate cement, CEM cement, was used to retard the progress of ERR and to preserve the affected teeth until the suitable age for receiving implants or bridges. In this 15-year-old patient, the resorptive process was regressed using CEM cement and the tooth remained functional till 22 years of age. The teeth were then extracted and implant treatment was initiated.
Conclusion: Currently there is no suitable protocol for the management of these cases. Newer biosilicate cements such as CEM cement help decelerate the resorptive progress and can be considered as a suitable protocol in intervening ERR.
Clinical significance: Losing an anterior tooth after ERR has functional, esthetic, phonetic, and psychological impacts on children and adolescents. Down regulating the resorptive process is critical and paramount in preserving esthetics and function until the time extraction and replacement can be done safely.
