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.
牙髓出现炎症时，继发髓腔内高压及血液循环障碍是牙髓炎出现不可逆缺血坏死的核心环节。单向滤膜减压保髓新技术的基本原理为：通过对髓腔开窗，采用具有阻止口腔微生物入侵牙髓组织的单向滤膜，持续对髓腔进行减压，改善牙髓血液微循环，待炎症的牙髓组织恢复正常后，再行永久性盖髓治疗。本研究应用此项技术，对1例不可复性牙髓炎进行活髓保存治疗，随访4年，效果良好。.
