Abstract:

Recent advances in vital pulp therapy(VPT)research, coupled with the widespread use of biomaterials, have led to an increase in the application of VPT. The indications for VPT are continually expanding, particularly for fully developed permanent teeth. Currently, one-way membrane decompression is being investigated as a possible treatment to preserve vital pulp in cases of irreversible pulpitis. This technology involves creating an access point in the pulp cavity and using the one-way membrane to prevent microorganisms from invading the pulp tissue. Additionally, it helps alleviate the high pressure in the pulp cavity caused by inflammation, thereby enhancing blood circulation within the pulp. This improvement is crucial for establishing a foundation for future vital pulp preservation treatments. A case of irreversible pulpitis caused by caries was reported, in which the dental pulp was preserved using the one-way membrane decompression. The results of a ten-month clinical follow-up indicate a positive outcome.
