Regeneración / revitalización pulpar en dientes permanentes inmaduros

Resumen

Introduction: Treatment of affected immature teeth is a challenging procedure. Immature teeth have wide canals, thin dentin walls and open apices, in addition to being more prone to fracture and with a poor long-term prognosis. Revascularization of an immature tooth attempts to preserve the teeth as long as possible, but there are failures because it is difficult to achieve optimal disinfection of the root canal system. Methods: An exhaustive search was carried out by consulting the electronic databases PubMed and Web of Science of the last 10 years, using keywords and eligibility criteria. Results: The search process yielded 635 total articles. After applying filters, eliminating duplicates and selecting articles by title and abstract, only 27 were for the present study. Conclusions: Pulp revitalization has high survival rates in the treatment of necrotic immature permanent teeth. Randomized clinical trials are needed to compare the effect of platelet-rich fibrin, platelet-rich plasma, and induced bleeding on the revitalization of a tooth with necrotic pulp. One of the main problems of pulp revitalization is coronal discoloration. Triple antibiotic paste is a very effective antimicrobial agent, but high concentrations could have a detrimental effect on stem cell survival.
