LSTR AND ITS POTENTIAL ROLE IN CONSERVATIVE MANAGEMENT OF NON-VITAL PRIMARY MOLAR: A CASE REPORT.

Lesion sterilization and tissue repair (LSTR) treatment is very effective in disinfecting the root canal using triple
antibiotic mixed in a suitable vehicle. This report is highlighting a case where LSTR therapy was done using triple
antibiotic paste in primary molar showing peri-radicular pathosis and root resorption. On one-year follow-up, the tooth
was asymptomatic with reduction in peri-radicular pathosis and root resorption. Thus, LSTR can be successful for
nonvital pulp therapy in primary teeth with peri-radicular pathosis and root resorption. And also, LSTR therapy can be
used as an alternative option to extraction in treating primary teeth with peri-radicular pathosis.
