Aim: The goal of endodontic research is to report interventions, techniques or protocols that are most likely to deliver the outcomes that are of most interest to both clinicians and patients. The development of a double-wavelength laser delivered concomitantly and through the same radial firing tip (RFT) may provide a unique combination of beneficial properties that may clinically surpass all previously reported laser-assisted protocols.
The aim is to present a rational literature overview that could support the adoption of simultaneous use 2780 and 940 nm wavelengths for smear layer removal and disinfection respectively.
Methods: In order to provide relevant clinical data, two distinct clinical cases of relatively high endodontic complexity are
reported with 1-year follow-up.
Results: The results of both clinical cases show the immediate remission of symptoms, absence of clinical complications and
complete radiographic healing.
Conlusions: Together with the available amount of literature that could support the effectiveness of these two wavelengths to
remove SL and to achieve deep dentin disinfection, it is possible to expect that this innovative combination of lasers delivered by
RFT may be of high clinical relevance in the near future.
