Special Issue Information

Dear Colleagues,

The etiology underlying most endodontic problems is the infection sustained by microbiological agents. Bacteria invade the endodontic space, leading to pulpitis, pulp necrosis, and later involving the apical periodontium. In treated teeth, persistent infection is the main agent of failure, with the persistence of disease. Enterococcus faecalis is the main species associated with the persistence of infection, although, day by day, an increasing number of species are showed to be linked to endodontic treatment failure due to intra- and extraradicular infections. Clinical shaping, disinfection, and filling of the root canal go to the microbiological aspects of infection. These clinical steps have to guarantee maximum performance on removal and disinfection of the root system. The goal of this Special Issue is to provide scientific evidence on the use of new clinical procedures and new endodontic materials designed to reduce and eliminate endodontic infection. Furthermore, the purpose of this Special Issue includes the evaluation of new shaping techniques, root canal filling, and disinfections aiming to eliminate and reduce the bacterial biofilm, with particular attention to those studies that investigate the microbiological aspects of endodontic infections. I am proud to invite you to present new studies, systematic reviews, and narrative reviews dealing with the microbiological aspects of endodontic infections and new clinical procedures aimed at reducing primary and secondary endodontic infection.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are 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 monthly 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 2000 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

This study aimed to examine the spatial cleaning effect of ultrasonic irrigation in simulated root canal with oblong cross section in the absence of antimicrobial agent. A 7-day E. faecalis biofilm was cultivated in a rectangular, simulated canal model and subjected to passive ultrasonic irrigation (PUI) with sterile saline for 5 minutes. After that, the biofilm was examined by confocal microscopy after bacterial viability staining at 58 sites around and beyond the endosonic file. Results showed that, at the vicinity of the file, the amount of viable bacteria ranged from 13.1% (2.75 mm from the tip) to 40.5% (4.5 mm level). Lesser amounts of live bacteria were observed within 1 mm from the vibrating file, which amount increased for sites farther away. At 3 mm distance, the amount of bacteria (35.5 to 64.4%) was significantly greater than areas situated close to the vibrating file (P < 0.01). Sites next to the anti-nodes of file had less bacteria remaining than sites near the nodes (P = 0.050). Apically (0.5 mm or more), the amount of bacteria was significantly greater than that at the file tip (16.4%) (P < 0.05). It was concluded that PUI is able to dislodge a single-species biofilm, provided that they are situated in close vicinity to the vibrating file. Full article
