Lesion sterilization and tissue repair - A non-instrumental procedure: A systematic review

A primary tooth affected by dental caries involving the pulp tissues along with periradicular tissues need conventional endodontic treatment. Due to certain factors these treatments may be contraindicated. In that case Lesion Sterilization and Tissue Repair (LSTR) therapy is the better option to be preferred. The process of LSTR is to increase the longevity of the primary tooth. This procedure eliminates, sterilizes the canal system, repairs and regenerates the tissue. It needs minimal instrumentation and includes placement of an antibiotic mixture in the pulp chamber to disinfect the root canals. It is also known as Non-instrumental endodontic treatment (NIET).
