What is one of the advantages of using lasers for endodontic procedures?

One of the significant advantages of using lasers in endodontic procedures is the improved smear layer removal. During root canal treatments, the mechanical instrumentation typically generates a smear layer, which consists of debris and bacteria that can impede the disinfection and sealing of the canal system. Lasers are effective in removing this smear layer due to their precision and focused energy delivery, which allows for a cleaner surface on the root canal walls. This ultimately contributes to better outcomes by facilitating more effective disinfection and improving the overall success rate of endodontic treatments.

In contrast, other options like increased thermal damage, a higher risk of infection, or longer procedure times do not reflect the benefits of laser use. Increased thermal damage is typically associated with improper use of laser energy rather than being an inherent advantage. A higher risk of infection is not accurate, as the effective disinfection properties of lasers can help reduce this risk. Lastly, longer procedure times contradict the purpose of utilizing lasers which aims to enhance efficiency in endodontic treatments.
