Prevalence and oral hygiene–related correlates of self-reported dentin hypersensitivity among Egyptian adults: a cross-sectional study

Abstract Background Dentin hypersensitivity (DH) is a prevalent clinical condition characterized by pain arising from exposed dentin in response to external stimuli. Despite its clinical relevance, epidemiological data from Egypt and the Middle East remain limited. This study aim...

Structure property and wear correlations in Al–Ni intermetallic coatings produced by atmospheric plasma spraying

Abstract Atmospheric plasma spraying (APS) is widely employed to fabricate protective coatings for engineering components requiring enhanced wear resistance and thermal stability. This study establishes structure property wear correlations in Al–Ni intermetallic coatings deposite...

Introducing the toroidal blade concept to small-scale horizontal axis wind turbine: A CFD study

This study evaluates the toroidal blade concept in horizontal-axis wind turbine design compared to conventional shapes. Both designs utilize the NACA 4412 airfoil, with the toroidal rotor featuring elliptical geometry. Three-dimensional transient CFD simulations using URANS equat...

Bianchi IX dynamics with a phantom field

Abstract We consider Bianchi IX dynamics of a Universe filled with a massless phantom field. Such an exotic matter source enables regimes impossible in vacuum or with a standard scalar field. In particular, two Kasner indices of BKL oscillations can be simultaneously negative, an...

Anticancer effects of a Captopril Montmorillonite formulation in oral cancer cells through apoptosis and redox modulation

Abstract Background Oral squamous cell carcinoma (OSCC) remains challenging due to the limited efficacy and toxicity of current therapies. This study investigates the anticancer potential of Captopril–Montmorillonite (CP–MMT) (nanoclay-based delivery system), a drug-repurposing a...

A preliminary antimicrobial investigation of lactobacillus bulgaricus probiotic supernatants as an intracanal medication against mature E. faecalis biofilm in an ex-vivo dentin blocks model

AIM: To provide a preliminary assessment of the antimicrobial potential of Lactobacillus bulgaricus probiotic against mature Enterococcus faecalis biofilm in dentin model under ex-vivo conditions using confocal laser scanning microscopy (CLSM). METHODS: Lactobacillus bulgaricus a...

Nano-boosted green coffee bean extract cream for enhanced anti-cellulite topical therapy: A randomized clinical trial

Cellulite is a prevalent cosmetic concern among postpubertal women, and the efficacy of conventional topical therapies remains limited. Green coffee bean extract (GCBE) exhibits antioxidant and lipolytic activities relevant to cellulite management; however, its topical performanc...

Numerical Investigation of a Compact Air-Cooled EV Battery Thermal Management System Using Circumferential Fins

Battery thermal management systems (BTMSs) are essential for maintaining the performance, efficiency, durability, and safety of electric-vehicle battery packs. Although fin-enhanced air-cooled BTMSs offer a simple and leakage-free cooling solution, their practical implementation...

Navigating market volatility: determinants of cost-estimation accuracy in Egypt’s construction sector

Accurate cost estimation is fundamental to the financial viability of construction projects, yet remains difficult in volatile developing economies. This study investigates the determinants of cost-estimation accuracy in the Egyptian construction industry and develops a validated...
