Summary: The study found that using diamond rubber polishing can improve the flexural strength of ultratranslucent zirconia, and different finishing/polishing techniques do not significantly affect Candida albicans adherence. The control group and diamond rubber polishing group showed higher flexural strength, while the diamond bur abrasion group exhibited the highest surface roughness.

Summary: High flexural strength is crucial for a ceramic armor component to withstand high tensile stresses and multiple hits, as it helps protect the structural integrity. The study examined the effect of different ZrO2 content on the flexural strength of Al2O3-ZrO2 composites, and found that the composite with 20% ZrO2 had the highest strength.

Summary: This study aimed to investigate the flexural strength of hot isostatically pressed nano 3 mol% yttria partially stabilised zirconia (HIP YSZ) and conventionally sintered micro 3 mol% yttria partially stabilised zirconia (Sintered YSZ). Forty bar-shaped specimens were prepared, with one group serving as control and the other cyclically loaded. The results showed that HIP YSZ had inferior flexural strength and surface polishability compared to Sintered YSZ, indicating that further research is needed before recommending them for clinical use.

Summary: Higher air-abrasion pressure (0.3 MPa, 0.4 MPa, and 0.5 MPa) resulted in decreased flexural strength, rougher zirconia surfaces, and more microcracks. The highest shear bond strength was achieved for zirconia surfaces abraded at 0.2 MPa and 0.3 MPa. Aging did not significantly affect the strength of all groups except the control group.

Summary: This study examined the effect of boron compounds on the mechanical and antimicrobial properties of hardened mortars. The results showed that the addition of borax or dicalcium hexaborate pentahydrate as additives decreased the compressive and flexural strength of the mortars, but the values remained within acceptable limits. The mortars containing boron compounds also exhibited antimicrobial activity against certain microorganisms, making them a potential alternative for creating antimicrobial surfaces in environments with mold and biodegradation problems.

Summary: Microbial infection plays a significant role in dental diseases and treatment outcomes. Silver-based biomaterials (AgBMs) have been extensively researched as efficient and relatively low-toxicity antimicrobial materials, with advances in nanotechnology enhancing their application value. AgBMs have a broad spectrum of antimicrobial properties, making them useful in various subspecialties of dentistry, and providing guidance for oral antimicrobial therapy.

Summary: The aim of this study was to analyze the influence of different surface treatments and surface roughness on the flexural strength of 3Y-TZP and 5Y-PSZ. Results showed that different surface treatments resulted in significant differences in flexural strength. Cutting the specimens in fully sintered state significantly reduced the flexural strength. Additionally, the ball-on-three-balls test yielded higher flexural strength compared to the piston-on-three-balls test.

Summary: This study aimed to evaluate the impact of sintering temperature on the Vickers microhardness and flexural strength of different layered zirconia materials. Results showed that the 4Y-TZP had higher microhardness and flexural strength compared to the 5Y-TZP at all sintering temperatures. Different sintering temperatures significantly affected the microhardness and flexural strength, with the highest values observed at 1450 degrees C. However, the layers did not significantly affect the microhardness.

Summary: This study evaluated the antimicrobial effect of four herbal plant extracts on mixed-species biofilms composed of Candida albicans and other pathogenic bacteria. The results showed that these extracts had inhibitory effects on the mixed-species biofilms, and some extracts even completely eliminated the biofilms. Therefore, the glycolic extracts of P. paniculata, H. virginiana, S. barbatiman, and G. sylvestre may be considered as potential alternatives for endodontic therapy.

Summary: The aim of this study was to evaluate the behavior of staining layer applied to high-translucency zirconia, feldspathic ceramics, and zirconia-reinforced lithium silicate surfaces against different antagonists. The results showed that the zirconia antagonist performed better against ceramics with high crystalline content, while the steatite antagonist, that is, an enamel analog, performed better against vitreous ceramics. Wear affects the surface roughness of ceramics, and additional firing for staining in zirconia-reinforced lithium silicate ceramics led to a loss of mass.

Summary: This study aims to evaluate the likelihood of survival and failure modes of extra-narrow implant systems with the same prosthetic components as standard-diameter implants. The results showed that using standardized prosthetic components for extra-narrow implants has a high probability of survival and a high characteristic strength, with failure modes restricted to the abutment. Therefore, this method can be a viable option for replacing anterior teeth.

Summary: This study proposes the development of a hybrid photocatalyst composed of titanium dioxide (TiO2) and graphitic carbon nitride (g-C3N4) to improve the efficiency of photocatalytic degradation of 4-chlorophenol (4CP) in aqueous effluent. The synthesis of the TiO2/g-C3N4 binary material was successful, resulting in optical and morphological modifications. The photocatalytic activity of TiO2/g-C3N4 under visible and simulated solar radiation showed significant improvement compared to pure TiO2, indicating the formation of an effective Z-scheme heterojunction between the semiconductors.

Summary: The demand for dental materials is increasing in order to achieve better performance than the currently available materials. In the field of dental restorative ceramics, there has been a transition from metal-ceramic systems to highly translucent multilayered zirconia to improve both mechanical properties and aesthetics. Ceramics are widely used in prosthetic dentistry due to their attractive clinical properties, but efforts are being made to develop materials that meet both mechanical requirements and aesthetic aspects.
