Background and Objectives: Periodontal disease (PD) is a multifactorial oral regularly caused by bacterial biofilms. Silver nanoparticles (AgNP) have offered good antimicrobial activity; moreover, there no available scientific information related to their effects in biofilms from patients with PD. This study reports the bactericidal activity of AgNP against Materials Methods: two average particle sizes were prepared characterized. Sixty collected (30 subjects) without PD subjects). Minimal...

The primary objective of this investigation was to synthesize a resin incorporating nanoparticles hydroxyapatite and silver (HA-NpsAg) enhance biocompatibility antimicrobial efficacy, thereby facilitating potential implementation within the dental industry. These enhancements aim ensure reliable, durable, functional, aesthetically pleasing restorations while concurrently reducing susceptibility bacterial colonization oral cavity. Hydroxyapatite powders were prepared using sol–gel method...

White spot lesions (WSLs) are very frequent alterations during orthodontic treatments causing demineralization of the dental enamel. Various have been developed to prevent WSLs; prevalence and incidence these remain significantly high. Although silver nanoparticles (AgNPs) demonstrated good inhibitory effects against several microorganisms, more studies about antiadherence activity on different appliance surfaces necessary. To determine effect AgNPs adhesion S. mutans brackets wires for...

This work describes a liquid allantoin-enriched pectin hydrogel with hydrophilic behavior that is supported by the presence of functional groups related to healing efficacy. A topical study shows effect application on surgically induced skin wound in rat model. Contact angle measurements confirm (11.37°), while Fourier-transform infrared spectroscopy indicates effectiveness (carboxylic acid and amine groups). Allantoin distributed surface inside amorphous surrounded heterogeneous...

The dental plaque is an oral microbiome hardly associated to be the etiological agent of caries and periodontal disease which are still considered serious health public problems. Silver nanoparticles (AgNPs) have demonstrated good antimicrobial properties affecting a wide variety microorganisms, including bacteria; however, there no scientific information that has evaluated effect AgNPs against clinical biofilms with disease. aim this study was determine substantivity effects in isolated...

Background and Objectives: Streptococcus mutans (S. mutans) is the main microorganism associated with presence of dental caries specific serotypes this bacteria have been related to several systemic diseases limiting general health. In orthodontics, white spot lesions (WSL), represent a great challenge for clinicians due fluctuation their prevalence incidence during conventional orthodontic treatments. Although silver nanoparticles (AgNP) demonstrated antimicrobial properties in...

BACKGROUND: Actinic prurigo is an idiopathic photodermatosis, the pathophysiology of which has been hypothesized to involve subtype IV type b (Th2) hypersensitive response, whereby IL4, IL5, and IL13 are secreted mediate production B cells, IgE, IgG4. OBJECTIVES: To examine association serum IgE levels clinical severity injuries. METHODS: This case-control study comprised patients with a histopathological diagnosis actinic prurigo, as well clinically healthy subjects, from whom 3cc...

Dental caries is an infectious oral disease originated by the presence of different microorganisms from well-defined biofilms. Many treatments for dental have been demonstrated to be successful protocols; however, incidence and prevalence remain still high. Although silver nanoparticles (AgNPs) shown excellent antimicrobial properties, even against bacteria, there no available scientific information that has evaluated activity AgNPs biofilms subjects with active caries. The objective this...

There has been different synthetic route used for the synthesis of zirconia mixed metal oxide nanoparticles. The methods coupled with other factors like concentration, PH, type precursor etc help to synthesize nanoparticles having physicochemical properties. This paper discusses routes sol-gel, hydrothermal and coprecipitation method formation in combination form nanoparticles, properties synthesized nanoparticle, their characterization application.

Abstract Background Actinic prurigo ( AP ) is an idiopathic photodermatosis that usually onsets during childhood and predominates in women. It characterized by the symmetrical involvement of sun‐exposed areas skin, lips, conjunctiva. Objectives This study aimed to analyze risk factors associated with using a case–control design. Methods All patients diagnosed 1990–2006 at Dr. Manuel Gea González General Hospital Mexico City were included. Respective controls recruited. Race, demographic,...

This study aimed to determine the general labor well-being of Latin American dentists according sociodemographic characteristics during COVID-19 pandemic.
