Abstract

Dentists treating patients have long been concerned about residual infections in the root canal system.Lesion sterilization and tissue repair (LSTR) therapy is a type of endodontic treatment in which root canal systems are disinfected by placing an antibiotic mixture after minimum or no equipment is used.It is increasingly being used to treat nonvital teeth instead of extractions, root canal treatments, and conventional pulpectomies.The content of this article covers the technique's development, purpose, indications, applications, and clinical steps that are required to use it.
