[One-way membrane decompression for vital pulp therapy in irreversible pulpitis: a case report].

Irreversible pulpitis is characterized by inflammation of the pulp, leading to secondary interstitial hypertension and blood circulation disorders. This study explores the development of one-way membrane decompression to alleviate interstitial hypertension in the inflamed pulp and prevent the invasion of oral microorganisms into the pulp tissue. Additionally, this technique aims to improve the microcirculation of the pulp tissue by consistently reducing the pressure within the pulp cavity. Once the inflamed pulp tissue is restored, permanent crown filling can be performed. In this paper, we present a case study involving a patient with irreversible pulpitis who underwent vital pulp treatment using the one-way decompressed membrane. A four-year follow-up evaluation revealed satisfactory outcomes.
