“…Among the new tendencies in the field of lasers, diode laser is interesting because of its small dimensions of the delivery tips, low cost, optional power output ranges and easy operating modes such as continuous wave, pulsed power, and gated mode. [67]…”

Background:Several disinfection techniques have been recently introduced with the main objective of improving root canal disinfection in the inaccessible areas of the root canal system. This in vitro study was done to evaluate the antimicrobial effect and viability of Enterococcus faecalis biofilms using conventional irrigation, EndoActivator (Dentsply, Tulsa Dental, USA), diode laser irradiation and photon-initiated photoacoustic streaming (PIPS).Materials and Methods:Root canals of 130 single rooted mandibular premolars, standardized to a uniform length of 20 mm were instrumented until finishing file, F1 (Universal Protaper Rotary System, Dentsply, Tulsa Dental Specialties, USA). After smear layer removal and sterilization, five teeth were randomly selected to assure sterility before bacterial inoculation. The remaining 125 samples were contaminated with E. faecalis suspension, incubated for 21 days and divided into five groups (n = 25). In Group 1; untreated group (positive control), the root canals were not subjected to any disinfection procedure. Sampling was performed within the canals and the colony-forming unit count was evaluated for 20 samples. Five samples were selected to visualize the pattern of colonization at Level 1 (4 mm from the apex) and Level 2 (1 mm from the apex) by confocal laser scanning microscopy. Samples in Groups 2-5 namely conventional needle irrigation, EndoActivator, diode laser and PIPS were subjected to their respective disinfection procedures. Postdisinfection sample evaluation criteria was followed for all groups as same as that for Group 1.Results:Diode laser displayed the highest antibacterial efficacy and least viable bacteria than the other three disinfection techniques.Conclusion:Diode laser group showed better antibacterial efficacy and least viable bacteria when compared to conventional needle irrigation, PIPS and EndoActivator groups in minimally instrumented, experimentally infected root canals.

“…The use of diode lasers in endodontics is an innovative approach to root canal disinfection because these lasers have the ability to penetrate deeper into dentinal tubules [3]. Diode lasers have become the method of choice due to their advantages including their ease of use and relatively small size compared to other types of lasers [13].…”

Objective: Candida albicans is the most frequently found fungi in persistent root canal infections; it can form a biofilm and penetrate into dentinal tubules. Endodontic irrigants, such as 2.5% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX), have antifungal properties, but limited penetration into dentinal tubules, which somewhat protects the C. albicans fungi. The use of a diode laser is an innovative approach in root canal treatments because it is able to penetrate deeper into the dentinal tubules. This study examined the effect of a 980-nm diode laser on the antifungal properties of 2.5% NaOCl and 2% CHX on C. albicans biofilms. Methods:The number of C. albicans colonies in the biofilms was recorded after irrigation using 2.5% NaOCl and 2% CHX. Then, the biofilms were radiated using a 980-nm diode laser.Results: Showed statistically significant differences between the use of the irrigants only and the use of the irrigants plus the diode laser treatment in the reduction of the C. albicans colonies in the biofilm. Conclusion:Diode laser is able to activate the antifungal properties of the 2.5% NaOCl and 2% CHX endodontic irrigants.

“…In all three cases biochemical root canal disinfection was supplemented with 810nm wavelength diode laser. Diode laser can eliminate microorganisms existing in main canal, lateral canals and dentinal tubules and can increase the success rate of endodontic therapy [10,11].…”
