OBJECTIVE The aim of this study was to compare the effectiveness of denture microwave disinfection and antifungal therapy on treatment of denture stomatitis. STUDY DESIGN Sixty denture wearers with denture stomatitis (3 groups; n = 20 each), were treated with nystatin or denture microwave disinfection (1 or 3 times/wk) for 14 days. Mycologic samples from palates and dentures were quantified a...

BACKGROUND AND AIMS Current chemical methods may not efficiently disinfect dental stone casts. The aim of this study was to investigate if microwave irradiation is effective for disinfection of stone casts. MATERIALS AND METHODS In this laboratory study, three groups (n = 162) of prepared spherical stone beads as carriers with a diameter of 10 mm were inoculated by separately soaking in three...

Background: This study investigated the color stability of reline resin after microwave disinfection and immersion in drinks for

The objective of this study was to determine the effect of simulated microwave disinfection on the tooth/acrylic resin impact strength. Acrylic molar teeth with a wax stick attached to the ridge lap were included in brass flasks. Specimens were made with Classico thermopolymerized acrylic resin, according to the groups: 1 and 5 - tooth with no treatment (control); 2 and 6 - tooth bur abrasion; ...

background and aims. although microwave irradiation has been used for disinfection of dental stone casts, there are concerns regarding mechanical damage to casts during the process. the aim of this study was to evaluate the effect of microwave irradiation on the compressive strength (cs) and diametral tensile strength (dts) of stone casts. materials and methods. in this in vitro study, 80 cylin...

Microwave energy has been used as an alternative method for disinfection and sterilization of dental prostheses. This study evaluated the influence of microwave treatment on dimensional accuracy along the posterior palatal border of maxillary acrylic resin denture bases processed by water-bath curing. Thirty maxillary acrylic bases (3-mm-thick) were made on cast models with Clássico acrylic res...

As the world is facing a Covid-19 pandemic, this virus teaches lesson about importance of on-site disinfection. On-site disinfection/sterilization with real-time monitoring biomedical waste generated from medical facilities mandatory to prevent hospital-acquired infection (HAI). In study, life cycle assessment two technologies, i.e., microwave (radiation-based) and autoclave (steam-based) were ...

Introduction and goal: various pathogens colonized in oral cavity that cause systemic disease such as pneumonia, endocarditis, and chronic obstructive pulmonary disease. Denture contamination with pathogenic microorganisms considered as a potential source of contamination between patients and dental staff. The study aimed to compare the effect of microwave radiation in the disinfection complete...

PURPOSE The purpose of this study was to evaluate, in vitro, the contamination of toothbrushes and pacifiers by Streptococcus mutans, and the efficacy of microwave and chlorhexidine for their disinfection. METHODS Sixty pacifiers and 60 toothbrushes were contaminated with S mutans and then divided into groups according to the disinfection protocol: Group 1-chlorhexidine solution; Group 2-micr...
