Dental decay is encountered most commonly among the pediatric age group and constitutes a major proportion of oral diseases. If left untreated at an initial stage will progress further and result in pulpal pathology. Furthermore, reluctance towards the treatment may lead to eventual loss of the tooth. Early primary tooth loss might have adverse implications for the growing permanent dentition. Thus, it is important to treat the cause as soon as possible. When caries progresses deep and causes pulpal pathology, pulpectomy is the conventional procedure done to save the tooth. However, for rare cases where pulpectomy cannot be done lesion Sterilization and Tissue Repair Therapy (LSTRT) can be used as an alternative. This technique used antibiotic combination and host tissue defence mechanism to treat the tooth less invasively.

• LSTRT (Lesion Sterilization and Tissue Repair Therapy),
• Triple Antibiotic paste (TAp),
• and conventional pulpectomy
