Summary: Major advances in ancient DNA research have allowed access to paleogenomic diversity, however, the functions and capabilities of this genetic material remain largely unknown. In this study, dental calculus samples from ancient humans were examined, leading to the discovery of a biosynthetic gene cluster that produces previously unknown metabolites called paleofurans. This demonstrates the possibility of obtaining natural products from ancient organisms and opens up new opportunities for exploration in this field.

Summary: This study aimed to evaluate the wear behavior and its effects on the flexural strength of silica infiltrated zirconia compared to glaze and polishing finishing treatments. The results showed that glazing caused the greatest antagonist volume loss, followed by silica infiltration and polishing. Polished zirconia had the highest flexural strength, but all worn groups showed a decrease in strength. Silica infiltration had slightly lower characteristic strength after sliding wear. Glazed zirconia had the highest roughness and hardness values, which decreased after wear testing.

Summary: The creation of buffer layers that improve adhesion to two different materials is an important area of research in dental materials science. In our study, we used FTIR and Raman microspectroscopy to assess the molecular features of the hybrid interface formed by a nature-like adhesive called polydopamine (PDA) in dental composites and enamel. We found that a homogeneous PDA-hybrid interface with increased O-Ca-O bond content can be created using traditional dental tissue pretreatment methods and a developed synthesis technology. This technology may have applications in minimally invasive dental restoration procedures in the future.

Summary: The aim of this study was to evaluate the influence of different opacities and thicknesses of lithium disilicate on the degree of conversion (DC) and bond strength (BS) of resin cements. Lithium disilicate ceramic samples with high translucency (HT), low translucency (LT), and medium opacity (MO) were used, with varying thicknesses. Both light-cured and dual-cured resin cements were tested for DC and BS. Results showed that an increase in thickness led to a decrease in DC for both cements, while affecting only the BS of the light-cured cement for MO ceramic. Comparing opacities, more translucent ceramics exhibited higher DC values. The LT and MO ceramics showed higher BS values than the HT. Dual-cured cement generally performed better in both analyses. Thicker and more opaque ceramic materials can decrease the DC of the cement, and the BS decreases with increasing thickness of more-opaque ceramics.

Summary: The acceleration of environmental pollution and global warming has led to increased environmental awareness and regulations to reduce carbon emissions. The automotive industry is shifting towards electric vehicles and urban air mobility, where composites are gaining attention for their increased driving range and green mobility. However, the tradeoff between performance and cost has hindered the mass adoption of composites. The latest developments focus on the application of biodegradable composites and robotic automation in composite manufacturing for eco-friendly and cost-effective production.

Summary: The study aimed to investigate the effects of curing modes on the conversion degree and polymerization shrinkage of dual-cure resin cements. The results showed that light-cured specimens had higher conversion degree and lower shrinkage compared to self-cured specimens over specific post-activation periods. There was a positive correlation between conversion and shrinkage. The findings are significant for clinical selection of resin cement products.

Summary: The aim of this study was to prepare resorbable polylactide fibers for periodontitis treatment using coaxial electrospinning, and to optimize the release of metronidazole (MNA) by reducing the initial burst effect. The results showed that the coaxial electrospun mats exhibited a retarded drug release compared to conventional fibers, and had a significantly higher antibacterial effect. The biocompatibility test also demonstrated that the coaxial mats had higher numbers of vital cells. These findings suggest that coaxial electrospun fibers can be potential drug delivery systems for local periodontitis treatment.

Summary: The effect of acidic media on the flexural strength and fatigue of CAD-CAM materials was investigated. Different materials were immersed in various media and their surface topography and roughness were analyzed. The results showed that the erosive media changed the surface roughness of the materials but did not compromise their flexural strength. Moreover, resin composite and hybrid ceramic were more resistant to cyclic fatigue compared to other materials.

Summary: This study investigated potential variations in polymerisation of light-and dual-cured resin cements photoactivated through four CAD/CAM restorative materials as a function of substrate thickness. The results showed that increasing substrate thickness reduced energy delivery to the luting cements and significantly affected the hardness of the cement discs. However, there was only a slight reduction in degree of conversion.

Summary: This study evaluated the influence of thickness and printing angle on the optical properties of 3D-printed dental restorative resins. The results showed significant differences in scattering, absorption, transmittance, and other properties between different thicknesses and printing orientations. Therefore, these factors should be considered to improve the biomimetic potential of 3D-printed dental restorative resins.

Summary: This systematic review compared the biomechanical performance of endocrowns and traditional core-crowns for the restoration of endodontically treated teeth with severe coronal structure damage. The majority of the studies found that endocrowns showed similar or greater survival rates and more favorable failure patterns than core-crown restorations, regardless of the tooth type. Endocrowns also produced lower stresses in the restorative and luting materials compared to core-crown restorations.

Summary: The purpose of this study was to evaluate alterations in the oral cells of older people from a Brazilian rural area using the micronucleus technique. The use of proton pump inhibitors (PPIs) was found to be a protective factor for the prevalence of micronuclei (MN). Age, sex, family income, tobacco use, alcohol consumption, and gastro-oesophageal reflux disease (GERD) were not associated with the number of MN and metanuclear changes (MCs) in oral mucosal cells.

Summary: This review focuses on the underlying science and technology of light curing in dental resin-based composites. It discusses the particle-wave understanding of light, the penetration ability of photons into bulk fill composites, the technology of LED light-curing units, and the criteria for absorption of photons by photo initiators. The implications for clinical practice, including design variables, selection criteria for LED-LCUs, and guidelines for their use, are also examined to ensure safe and effective light-curing procedures.
