Aim: The aim of the present study was to investigate application of sealants in an epidemiologic cross-sectional study, and to conduct a survey of the opinions of dentists on the application of sealants in their practice.
Patients And Methods: The epidemiologic study included 960 children aged 7 to 14, selected at random from schools in Plovdiv and 630 dentists from Plovdiv and other regions in Bulgaria. Data were analysed using alternative and nonparametric analysis (chi square test); the level of significance was set at P < 0.05.
Results: The epidemiologic survey suggest that the use of sealants to prevent occlusal caries in childhood is not a usual practice, but rather an exception. Bulgarian dentists are familiar with the indications and means of applying prophylactic protection of teeth in childhood.
Conclusions: The results of the epidemiologic study and the survey indicate clearly that additional motivation is needed to boost the use of this type of prophylaxis to prevent occlusal caries in childhood.

Powder-based hemostatic materials have offered unprecedented opportunities for the effective sealing and repair of irregularly shaped wounds and high-pressure, noncompressible arterial bleeding wounds caused by surgeries, traffic accidents, and wartime injuries. However, inadequate adhesion to bleeding wounds and poor hemostasis in biological tissues remains challenging. Herein, we report a self-gelling hemostatic powder based on polyacrylic acid/polyethyleneimine/polyethylene glycol (named PPG) for rapid hemostasis and effective antibacterial ability.

The current research is devoted to integrating naturally renewable cardanol derivatives into one-component silyl-terminated-polyether-based prepolymer systems to improve climatic resistance and obtain materials with versatile mechanical properties that could be significant to various sectors of the economy. Various cardanol-type products are used in industries that require high climatic resistance, and thus combining cardanol with commercially available silyl-terminated polyether prepolymers would improve its material climatic resistance, maintaining its market and application value as well as improving material sustainability. The results obtained in this work show that depending on how the cardanol prepolymer Ultra Lite 513 is modified, it is possible to increase the elasticity (670%) or tensile strength (104%) of the material as well as significantly increase the climatic resistance of the material, thus improving the quality and sustainability of the adhesive compared to existing silyl-terminated-prepolymer-based adhesives on the market.

This study evaluated the influence of six resin composite coating agents on color stability and surface roughness after toothbrushing abrasion. Discs (Ø6 mm x 2 mm) of nanofilled resin composite (Filtek Z350XT) were prepared for application of coating agents (n=10): control (absence), two surface sealants (PermaSeal and BisCover LV), two adhesive systems (Scotchbond Multi-Purpose Adhesive/3M Oral Care and Single Bond Universal), and two modeling liquids (Modeling Resin and Composite Wetting Resin). CIELab*, WID, and color change (ΔEab, ΔE00, and ΔWID) were analyzed at baseline, after finishing and polishing, after application of coating agents, after coffee staining (simulating 30 days and one year of staining), and after toothbrushing abrasion.

Gluing is a critical step in aircraft sealing assembly, with glue profile inspection serving as the final quality assurance measure to ensure consistency and accuracy of the sealant coating, allowing timely detection and correction of defects to maintain assembly integrity and safety. Currently, existing glue inspection systems are limited to basic inspection capabilities, lack result digitization, and exhibit low efficiency. This paper proposes a 3D inspection technology for sealant coating quality based on line-structured light, enabling automated and high-precision inspection of sealant thickness, sealant width, positional accuracy, and overlap joint sealant contour through geometric computation.

Article Synopsis
- HPV genotype plays a crucial role in predicting cervical cancer risk, and using genotyping can improve management strategies for HPV-positive patients during cervical screening.
- The ScreenFire HPV RS assay, combined with the Zebra BioDome technology, facilitates efficient testing by processing up to 96 samples in about an hour while minimizing contamination risks with fewer pipetting steps.
- Validation studies on the Zebra BioDome showed excellent repeatability and accuracy when compared to the standard assay, suggesting it could streamline HPV testing and improve accessibility for point-of-care diagnostics in low-resource settings.
