Special Issue Information

Dear Colleagues,

For this Special Issue, titled 'Technological Innovations and Tools in Dental Practice', we invite contributions exploring the development and application of advanced monitoring tools and techniques that enhance diagnostic, preventive, and therapeutic approaches in dentistry. This Special Issue focuses on innovative technological solutions employed by dental professionals to improve patient outcomes. We welcome submissions detailing the integration of digital dentistry, imaging techniques, artificial intelligence, and wearable devices in clinical practice. Authors should highlight the practical applications of these technologies in areas such as operative dentistry, implantology, orthodontics, endodontics, prosthetics, and tissue engineering. Additionally, we encourage discussions on the implications of big data and data mining in dentistry, the use of robotics, and the future of nanodentistry. Contributions that address the educational needs and policy changes necessary to support these advancements are also valued. This Special Issue aims to provide a platform for sharing cutting-edge research and practices that underscore the critical role of technology in the evolution of dental care.

The purpose of this study was to evaluate the bactericidal effect of 270 nm UV-C light-emitting diode (LED) light delivered through a newly designed prototype device with thin optical fiber against Enterococcus faecalis (E. faecalis). The prototype device, developed to integrate UV-C light into a thin optic fiber (diameter 124 µm) connected to a UV-C LED (Luminous Device; Sunnyvale, CA, USA) via a specialized double-lens system that focuses divergent light to achieve a 65 mm working distance and a numerical aperture of 0.22. E. faecalis, was cultured at 37 °C under aerobic conditions for 24 h. The UV-C LED optical fiber was positioned 10 mm above the bacterial culture prepared in the wells of a 96-well plate. The E. faecalis cells were exposed to UV-C irradiation for 0, 10, 30, 60, 90, 120 and 180 s. Following irradiation, the OD600 values were measured after incubation at 37 °C for an additional 24 h. The data were statistically analyzed using one-way ANOVA, followed by Tukey’s honestly significant difference (HSD) test at a significance level of 0.05. UV irradiation at 270 nm significantly reduced E. faecalis growth in a time-dependent manner (p < 0.05). No significant changes were observed at 0 and 10 s, while peak reductions occurred at 120 and 180 s, with effects beginning at 30 s and increasing over time. The 270 nm UV-C wavelength was highly effective in bactericidal action against E. faecalis. The custom-designed UV-C delivery system effectively integrated the light source into a thin optical fiber, allowing for efficient UV-C light transmission and demonstrating its potential for application in narrow spaces such as root canals.

The aim of this study was to evaluate the antibacterial effects of Paeonia lactiflora (PL) extract on oral microcosm biofilms and determine its usefulness as a natural alternative to current antimicrobial agents. Oral biofilms were cultivated on hydroxyapatite disks using human saliva for 2 days, following which they were treated with 1.5 mL of distilled water (DW), 30 μg/mL of PL extract, or 0.12% chlorhexidine gluconate (CHX) once daily for 3 days. Antibacterial effects were assessed by measuring red fluorescence intensity (RatioR/G), bacterial viability (RatioG/G+R), and aciduric bacterial counts. RatioR/G was evaluated using quantitative light-induced fluorescence digital imaging. RatioR/G and RatioG/G+R in the PL group were 0.94-fold and 0.73-fold lower than those in the DW group (p < 0.001 and p = 0.011, respectively) and comparable to those in the CHX group (p = 0.356 and p = 0.964, respectively). Aciduric bacterial counts in the PL group were 0.97-fold lower than those in the DW group (p < 0.001), with no significant difference from those in the CHX group (p = 0.892). Thus, the antibacterial effect of PL extract was comparable to that of CHX; this suggests its potential as a natural alternative for managing oral biofilm-associated diseases. Full article
