The effect of silver and calcium fluoride nanoparticles on antibacterial activity of composite resin against : An study.

Background: Recurrent caries were attributed to the lack of antibacterial properties of the dental materials. Silver nanoparticles (AgNPs) and calcium fluoride nanoparticles (CaF2NPs) are broad-spectrum antibacterial agents. The object of the study was to investigate the antibacterial properties of composite-incorporated AgNPs and CaF2NPs on .

Effect of Silver Diamine Fluoride and Potassium Iodide on Microleakage of Composite Resin in Anterior Primary Teeth.

Aim: One of the preventive interventions for early childhood caries is the use of silver diamine fluoride (SDF), which works uniquely in the prevention of caries. The suggested method to minimize the discoloration of SDF is the use of potassium iodide (KI). However, there are concerns about the bonding properties of dentin after the application of SDF-KI.

The effect of pediatric drugs on color stability of bulk-fill and conventional composite resins.

The long-term use of pediatric medications can lead to discoloration of dental restorations, which affects their durability and longevity. The present in vitro study evaluated the effects of commonly used pediatric medications on the color stability of a conventional and a bulk-fill composite resin. For this study, 80 disc-shaped specimens of each composite were prepared in molds with a diameter of 6 mm and thicknesses of 2 or 4 mm (n = 40 per thickness per material).

Are oral health behaviors associated with metabolic syndrome in the Azar cohort population?

Objective: Considering the rising prevalence of metabolic syndrome (MetS), this study aimed to investigate the relationship between MetS and its components with oral and dental health in the adult population of the Azar cohort.

Methods: In this cross-sectional study oral health care behaviors, DMFT (decayed, missing, and filled teeth) index, and demographic data related to 15,006 patients (5112 in the MetS group and 9894 in the healthy group) of the Azar Cohort population aging from 35 to 70 were collected using appropriate questionnaires. The definition of MetS was based on the National Cholesterol Education Program Adult Treatment Panel III (ATP III) criteria.

Effect of the COVID-19 pandemic on depression, perceived stress and hypochondria of frontline dental staff (FDS): A cohort study.

Background: The coronavirus 2019 (COVID-19) pandemic had several mental effects on medical staff.

Objective: This study intended to evaluate deviations in Frontline Dental Staff (FDS) depression, perceived stress and hypochondria during the COVID-19 outbreak, and to assess whether the existence of potential risk-factors influenced these symptoms over time.

Methods: This prospective cohort study surveyed FDS three periods from February 1, 2021 to April 8, 2022.
