An In Vitro Study to Assess the Effect of Cigarette Smoke on Color Stability and Surface Roughness of 3D Printed, Milled, and Traditional Provisional Crown and Bridge Materials.

Objectives To assess the influence of cigarette smoke (CS) on the color and surface roughness of 3D printed, milled, and traditionally fabricated provisional crown and bridge (PC&B) materials. Materials and methods 112 disc-shaped samples were made employing four techniques and materials (28 per group) to fabricate PC&B prostheses. Specimens were fabricated using standard protocols, such as 3D printing, milling, conventional bis-acrylic resin, and traditional autopolymerizing polymethyl methacrylate (PMMA) resin.

EEG-based deception detection using weighted dual perspective visibility graph analysis.

Deception detection is a critical aspect across various domains. Integrating advanced signal processing techniques, particularly in neuroscientific studies, has opened new avenues for exploring deception at a deeper level. This study uses electroencephalogram (EEG) signals from a balanced cohort of 22 participants, consisting of both males and females, aged between 22 and 29, engaged in a visual task for instructed deception.

The Effect of Green-Synthesized Nanoparticles on Dental Caries-Causing Bacteria: A Systematic Review.

Introduction: In this study, a comprehensive search was conducted across multiple databases, including PubMed, Google Scholar, SID, Scopus, Medline, and Web of Science, as well as selected herbal medicine journals. The inclusion of herbal medicine journals was justified by the growing interest in green-synthesized nanoparticles derived from plant extracts, which are relevant to the focus of this review. Articles published between 2015 and 2023 were evaluated.

Prevalence of HPV in anal cancer: exploring the role of infection and inflammation.

Anal cancer incidence is rising globally, driven primarily by human papillomavirus (HPV) infection. HPV, especially high-risk types 16 and 18, is considered a necessary cause of anal squamous cell carcinoma. Certain populations like people living with HIV, men who have sex with men, inflammatory bowel disease patients, smokers, and those with compromised immunity face elevated risk.
