Objectives: Orthodontic bracket bond failure is an obstacle in clinical orthodontics. This study investigated the influence of pH cycling on the shear bond strength (SBS), adhesive remnant index (ARI), and survival probability of adhesive-precoated flash-free ceramic brackets.
Materials And Methods: Forty mandibular premolars were randomly divided into two groups ( = 20): C: noncoated orthodontic brackets, and F: flash-free adhesive-precoated orthodontic brackets.
Anthocyanins are known as an antioxidant, and their water-soluble purple-colored pigments are very nutritive. Therefore, the present study investigated the antioxidant activity of black rice anthocyanins nano-composite against infertility induced by AlCl3 in rats. Anthocyanin silver nanoparticles (An-AgNPs) were prepared by reducing black rice anthocyanin with the metallic ions.

Methods: The study was conducted in 3 phases. In phase I, a targeted literature review was performed to gather relevant information on the implementation of MCDA in healthcare decision making.
Article Synopsis
- Saliva contains various biomarkers that can help diagnose multiple oral and systemic disorders, making it a significant tool for clinical diagnostics.
- A comprehensive review was conducted using the PRISMA framework, analyzing 212 papers found in major research databases, ultimately evaluating 54 studies.
- The findings highlight that saliva can diagnose several diseases as effectively as traditional methods, demonstrating its potential as an accessible source for medical biomarkers.
Background: Waterpipe tobacco smoking (WTS) is an issue all over the world, although it is particularly prevalent in the Middle East, and Southeast Asia. The genotoxic effects of smoking were reported to be associated with nucleus abnormalities such as micronuclei (MN), karyorrhexis (KR), karyolysis, pyknosis, binucleates, broken eggs, condensed chromatin in exfoliated buccal mucosal cells, and was believed to be associated with apoptosis of cells and was not correlated to the exposure time.
Aim: The aim of this study was to evaluate and compare the cytotoxic and genotoxic effects of cigarette and WTS on buccal mucosa.
