Special Issue Information

Dear Colleagues,

Nowadays, the use of and research on lasers is an established field in dentistry. Their applications continue to expand as more evidence of their efficacy is provided. Moreover, it has become clear in endodontics that laser applications can make a difference to debris and smear-layer removal and its interaction with the biofilm, resulting in enhanced disinfection. Lasers also allow for the better preservation of the pulp thanks to the evaluation of real pulp vitality (Laser Doppler Flowmetry); techniques such as FACE (fluorescence aided caries excavation) are helpful to make the distinction between infected and affected layers, resulting in stepwise excavation, and pulp capping with laser results in very high success rates. Laser bleaching is effective for the discoloration of sclerotic teeth without the need for a walking bleach; thus, this the technique belongs to the field of minimal invasive dentistry. The treatment of dentinal hypersensitivity with lasers has become a recognized technique. Recent advances in technology such as microsecond pulses with associated high-power density, the interaction of laser light with light-activated nanoparticles, photodisinfection with other dyes, and recent fluorescence scanning techniques open up new perspectives.

This Special Issue is interested in all aspects of the application of lasers in endodontics. Clinical, as well as basic, research is welcome. Manuscripts dealing with innovative approaches and techniques that make a difference to the conventional approaches and their safety are of high interest.

Thank you very much!

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Dentistry Journal is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1000 CHF (Swiss Francs).

Activation techniques are essential for root canal disinfection but may result in incomplete removal of bacteria. The aim of our study was to assess the antibacterial action of sonically, ultrasonically and laser-activated irrigation and 5.25% sodium hypochlorite (NaOCl) on Enterococcus faecalis in an infected tooth. Forty-four extracted mandibular premolars were mechanically prepared, sterilized, and inoculated with E. faecalis for 1 week. Bacterial counts after inoculation were evaluated in 4 randomly chosen teeth, remaining root canals were divided into 4 groups. Group A: laser-activated irrigation by photon-induced photoacoustic streaming, Group B: the sonic irrigation by EDDY, Group C: ultrasonic irrigation by EndoUltra, and Group D: 5.25% NaOCl. Colony forming unit (CFU) counts were measured and Kolmogorov–Smirnov, Wilcoxon, Kruskal–Wallis and Mann–Whitney tests were used to determine differences. The mean of CFU was found to significantly decrease in group D, 2110 ± 1015.93 (p < 0.001). Changes in measurement levels followed the same trend over time in groups A 27.40 ± 30.15, B 81.3 ± 85.68 and C 44.40 ± 67.12 (p = 0.141). The average CFU after irrigation in all groups was significantly greater than 0. Within the limitations of this study, all activation techniques were superior to NaOCl 5.25% in reducing E. faecalis from the infected tooth model. Full article
