“…In the present case report, and in similarity with the available clinical data [104,105,110], the use of a resin-based sealer (Topseal, Dentsply-Maillefer) has demonstrated high affinity for dentin penetration and hermetic seal.…”

“…In contrast with the previous reports using RFT in straight canals of the anterior teeth [104,110], the RFT used in these two clinical cases were moved in a spiralling motion along the root canal walls. The aim was to facilitate the fibre withdrawing motion and to possibly overcome any ledging that may occur in apical thirds of curved canals.…”

“…Despite the well-reported in vitro advantages of several lasers in endodontics, the Er,Cr:YSGG laser is the only one supported by clinical data demonstrating its potential benefits and long-term outcomes [104,105,110]. Lately, a dualwavelength approach using two lasers in combination through the same fibre has been reported as a safe, promising concept to be incorporated for root canal therapy (Fig.…”

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.

“…The removal of biofilm from the inner walls of the canal is further enhanced when irrigation is assisted by ultrasonic or laser activation [32, 33]. However, several clinical studies have shown no significant clinical advantage of these procedures over conventional protocols [34–36] and the extent in which they affect biofilms located in remote regions of oval-shaped canals, lateral canals and tubules, is still unknown [37]. Hence, intracanal medicaments are inserted into root canals intending to restrict bacterial regrowth and supply continued disinfection [38].…”

Efficacy and potential use of novel sustained release fillers as intracanal medicaments against Enterococcus faecalis biofilm in vitro

Background Enterococcus faecalis is a bacterium frequently isolated after failed root canal therapy. This study analyzed the antibacterial and antibiofilm effects in vitro of sustained-release fillers (SRF) containing cetylpyridinium chloride (CPC) against vancomycin resistant E. faecalis . Methods First, the solidification capability was tested by introducing liquid SRF into phosphate buffered saline, followed by 30 s of vortexing. The antimicrobial effects of SRF-CPC against static monospecies biofilms were analyzed with a metabolic assay. Inhibition of biofilm formation was tested by exposing daily refreshed E. faecalis suspensions to SRF-CPC for 9 weeks. To evaluate the effects of SRF-CPC against preformed biofilms, biofilms were grown for 1, 3 and 7 days, and then treated with SRF-CPC for 24 h. Biofilm kill time was tested by applying SRF-CPC to a 3-day-old biofilm and measuring its viability at different time points. All experiments were compared to Placebo SRFs and to untreated control biofilms. Data were analyzed with two-way ANOVA followed by Tukey’s test. Results were considered significant at P < 0.05. Results The liquid SRF solidified within seconds and no structural changes were observed after 30 s of vortexing at maximum speed. SRF-CPC inhibited E. faecalis biofilm formation for 7 weeks and significantly reduced its viability in weeks 8 and 9. Mature biofilms grown for 1, 3 and 7 days were destructed by SRF-CPC in less than 24 h. Fifty percent of a 3-day-old biofilm was destructed in 2 h and complete destruction occurred in less than 12 h. ( P < 0.05 in all cases, compared to SRII-Placebo). Conclusions SRF-CPC’s physical properties and long-lasting anti-biofilm effects make it a promising coadjuvant medication for endodontic therapy.

“…evaluated the outcome of using an Er,Cr:YSGG laser with a radial firing tip (RFT) that can ensure uniform intracanal illumination. The investigators compared the laser technique vs conventional use of 3% sodium hypochlorite and interim calcium hydroxide paste in teeth with chronic apical periodontitis (Martins et al., ). The laser protocol included RFT2 (tip length 25 mm, fiber outer diameter 275 μm, 140 μs, 37.5 mJ, 20 Hz) and RFT3 (tip length 21 mm, fiber outer diameter 415 μm, 140 μs, 62.5 mJ, 20 Hz) at the first and second appointments respectively, four times each, moving at 2 mm/s from apical to coronal direction.…”

Learning from clinical phenotypes: Low‐dose biophotonics therapies in oral diseases

This narrative review on the use of biophotonics therapies for management of oral diseases is written as a tribute to Prof. Crispian Scully. His seminal contributions to the field are highlighted by the detailed, comprehensive description of clinical presentations of oral diseases. This has enabled a more thorough, fundamental understanding of many of these pathologies by research from his group as well as inspired mechanistic investigations in many groups globally. In the same vein, a major emphasis of this narrative review is to focus on the evidence from human case reports rather than in vitro or in vivo animal studies that showcases the growing and broad impact of biophotonics therapies. The similarities and differences between two distinct forms of low-dose biophotonics treatments namely photodynamic therapy and photobiomodulation therapy are discussed. As evident in this review, a majority of these reports provide promising evidence for their clinical efficacy. However, a lack of adequate technical details, precise biological rationale, and limited outcome measures limits the current utility of these treatments. Future investigations should attempt to address these shortcomings and develop better designed, rigorous, controlled studies to fully harness the tremendous potential of low-dose biophotonics therapies.
