Vital pulp therapy of permanent teeth with irreversible pulpitis.

Traditionally, vital pulp therapy (VPT) is mainly indicated for young permanent teeth. However, in recent years, VPT has been increasingly applied to mature permanent teeth. VPT was previously thought to be effective only for teeth with normal pulp or reversible pulpitis. However, an increasing body of evidence has demonstrated that VPT can successfully manage permanent teeth with irreversible pulpitis or apical periodontitis. This work discusses which teeth with irreversible pulpitis or apical periodontitis are suitable for VPT, the recommended method to evaluate and select this kind of case, and the clinical procedure involved to operate such a case.
