Efficacy of lesion sterilization and tissue repair using different materials in primary molars: A case series

The concept of lesion sterilization and tissue repair (LSTR) therapy involves the use of a triple antibiotic mixture in a suitable vehicle, which is used to disinfect the root canal systems. This series highlights three cases where pulp therapy using modified 3 Mix antibiotic paste and chloramphenicol, tetracycline, and zinc oxide-eugenol paste was attempted in primary molars with or without pulpal and periapical involvement. Successful clinical and radiographic assessment after 6 months advocates LSTR therapy as an alternative option to conventional pulp therapy.
