Background: Conventional chemical root canal disinfection has been around for generations but it has its own drawbacks. Because of this there is a need for a better alternative for intracanal disinfection method. This alternative can be in the form of lasers, especially due to recent advances in laser technology. Methodology: The aim of the study is to compare chemical vs laser disinfection in primary root canal. This method has been tested in permanent teeth but not in primary teeth, this study was performed to evaluate the efficacy of laser disinfection compared to chemical disinfection. Results: The use of chemical disinfection by 5 ml of 5.25% NaOCl led to 96.7% microbial reduction against diode laser which achieved 97.7% reduction as compared to baseline microbial count and 34.4% reduction after irrigation using normal saline solution. Conclusion: Diode laser has similar root canal disinfection efficacy as compared to 5.25% NaOCl in primary canals. Diode lasers can be used as an alternative to chemical disinfection.
