Special Issue Information

Dear Colleagues,

This Special Issue provides a forum for the publication of papers on the technical, experimental, and clinical aspects of the use of dental lasers, including lasers in operative dentistry, cariology, periodontology, endodontics, implantology, prosthodontics, orthodontics, aesthetic dentistry, and oral surgery. In addition, this Special Issue will publish papers on the dental application of new lasers, basic laser–tissue interactions, photobiomodulation, photodynamic therapy, low-level laser therapy, photodiagnostics, and temporomandibular joint and muscle disorders and TMJ pain management.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2300 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 presents a color digital holography (CDH) detection system that includes the optical path and a numerical calculation program to detect tooth erosion under different acid-etching conditions. Etched cattle enamel samples were pressurized within the elastic interval, and the CDH detection system was used to rebuild the three-dimensional deformation field of these samples. Young’s modulus of these samples was employed to evaluate the mechanical properties of enamels by statistical methods. The results show that Young’s modulus of enamel decreases with the increase in etching time, while it decreases slightly with the increase in the etching temperature, and the etching temperature has no effect on the non-etched enamels. Moreover, the detection process proves the CDH detection system has the advantages of high precision, full-field detection, and being non-destructive, fast, and stable. It is expected to have broad application potential for CDH detection systems in the detection of tooth erosion. Full article

Revascularization has been incorporated into endodontic practice and become a viable treatment alternative for immature teeth with pulp necrosis. Thorough disinfection of the root canal is a key factor for successful revascularization. An erbium: yttrium–aluminium–garnet (Er: YAG) laser has been proved advantageous for efficient root canal disinfection. This article reports one case of periapical periodontitis caused by a fractured occlusal tubercle. Revascularization assisted by Er: YAG laser irrigation was carried out with long-term follow up. During the process of treatment, we opened drainage to relieve the acute symptoms first. The necrotic pulp was removed, and then the root canal was rinsed with 0.5% sodium hypochlorite (NaOCl) solution assisted by Er: YAG laser irrigation, dried, and filled with a triple-antibiotic paste. After two weeks, the intracanal medication was removed, and 9 mL of whole vein blood was taken from the patient to prepare concentrated growth factor (CGF) after failing to induce enough blood into the canal system by over-instrumenting. The newly prepared CGF was transferred into the root canal. A 3 mm mineral trioxide aggregate (MTA) was placed directly on the thrombus of the CGF and then restored with glass-ionomer cement (GIC). The case was followed up for more than four years to record the clinical symptoms and imaging manifestations. Er: YAG irrigation is an efficient root canal disinfection protocol with the advantages of easy operation and minimal risk, which might be applicable to the revascularization of necrotic immature permanent teeth.
