Root Canal Disinfection in Primary Molar During Pulpectomy Procedure using S1 PIOON LASER

The outcome of root canal treatment is based on efficient disinfection of the root canal system and prevention of reinfection. Pulpectomy is defined as a root canal procedure for pulp tissue that is irreversibly infected or necrotic due to caries or trauma in primary teeth. The root canals are debrided and shaped with hand or rotary files. However the instrumentation and irrigation with an inert solution alone cannot adequately reduce the microbial population in a root canal system, disinfection with irrigants such as sodium hypochlorite and/or chlorhexidine is an important step in assuring optimal bacterial decontamination of the canals. But these have disadvantages for example as it is a potent tissue irritant, sodium hypochlorite must not be extruded beyond the apex. We can use LASER to disinfect the canals. Also in primary teeth due to complex pulpal anatomy and curved canals it is difficult to completely remove the pulp and hence the bacterial load. Current chemomechanical cleaning methods do not always achieve these goals, and insufficient root canal disinfection is the main reason for endodontic failure. LASER can aid us to achieve this impossible task of disinfection of root canal system as a whole including the lateral and accessory canals.
