In vitro comparison of peracetic acid and autoclave sterilization in the corrosion of orthodontic pliers: a pilot study

ABSTRACT Introduction: The most currently recommended method for sterilization of orthodontic pliers is the autoclave, while peracetic acid has also been shown to be effective in the chemical sterilization process. Objective: This study sought to compare the corrosive effects of peracetic acid and auto...

Análise de pH externo radicular, pós irrigação e medicação intracanal com diferentes materiais

O objetivo do presente estudo foi avaliar o pH externo radicular de dentes bovinos pré-selecionados. Neste estudo foram utilizadas soluções irrigadoras, ácido peracético 0,25%, hipoclorito de sódio 2,5% e hipoclorito de sódio 6% associadas ao EDTA e as medicações intracanais, ultracal, hidróxid...

Effect of peracetic acid used as single irrigant on the smear layer, adhesion, and penetrability of AH Plus

Abstract The aim of this study was to evaluate the effect of peracetic acid (PAA) as a single irrigant on the smear layer, on the intraradicular dentinal bond strength, and on the penetrability of an epoxy-based resin sealer into the dentinal tubules. A total of 120 roots were distributed into 4 groups a...

Avaliação de danos em nasofibroscópio flexível desinfetado com ácido peracético

Rev. SOBECC; 22 (3), 2017
Objetivo: Avaliar a ocorrência de possíveis danos em nasofibroscópios causados pela desinfecção em ácido peracético. Método: Pesquisa aplicada. Três nasofibroscópios novos, submetidos à desinfecção com ácido peracético, foram acompanhados e fotografados em microscópio esteroscópio, ao lo...

Effects of different irrigation regimes in physico-chemical properties of dentin and consequences of changes in the adhesion of microorganisms and AH Plus sealer

Besides of the desired effects, the chemical solutions used to assist the endodontic instruments in the cleanliness and disinfection of the root canal system can also cause changes in the physicochemical properties of dentin, and consequently affect the adhesion of endodontic sealers and microorganisms t...

Effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin

Abstract This study aimed to evaluate the effect of final irrigation protocols on microhardness reduction and erosion of root canal dentin. Sixty root canals from mandibular incisors were instrumented and randomly divided into six groups (n = 10) according to the irrigant used: QMiX, 17% EDTA, 10% citric...

Effect of peracetic acid on biofilms formed by Listeria monocytogenes strains isolated from a Brazilian cheese processing plant

ABSTRACT This study aimed to investigate the effect of peracetic acid (PAA, 0.5%) on adherent cells of three strains of Listeria monocytogenes strains belonging to serotypes 4b and 1/2b that had been previously isolated from the environment of a Brazilian cheese plant. The assays were conducted using pol...

Análise da eficácia antimicrobiana do ácido peracético na desinfecção de moldes de hidrocoloide irreversível

Introdução: Nos últimos anos, o ácido peracético tem sido utilizado na Odontologia para desinfecção de moldes de hidrocoloide irreversível. Objetivo: Avaliar a eficácia antimicrobiana do ácido peracético nas técnicas de nebulização e pulverização, em moldes de hidrocoloide irreversível....

Sterilizing elastomeric chains without losing mechanical properties. Is it possible?

OBJECTIVE: To investigate the effects of different sterilization/disinfection methods on the mechanical properties of orthodontic elastomeric chains. METHODS: Segments of elastomeric chains with 5 links each were sent for sterilization by cobalt 60 (Co60) (20 KGy) gamma ray technology. After the procedur...

Force decay in orthodontic elastomeric chains after immersion in disinfection solutions

Braz. j. oral sci; 13 (4), 2014
Aim: To evaluate the force decay of orthodontic elastomeric chains after immersion in disinfecting solutions. Methods: One-hundred and fifty segments of elastomeric chains were divided in 3 groups: Control group - no disinfection; Chlorhexidine group - disinfection in 0.12% chlorhexidine digluconate solu...
