Evaluation of surface roughness of a nanofill resin composite after simulated brushing and immersion in mouthrinses, alcohol and water

Abstract

This study investigated the alteration of surface roughness of the nanofill composite Filtek Z350 3M/ESPE ® , caused by simulated brushing associated with the use of mouthrinses with or without alcohol. Sixty specimens were prepared and distributed into six groups: distilled water, ethylic alcohol, Listerine ® Vanilla Mint, Plax ® without alcohol, Oral B ® without alcohol and a control group. Each group was submitted to two intercalary 5,000 simulated brushing cycles. At the end of each cycle, the specimens were washed in tap water and immersed for two cycles of six hours equivalent to one year of daily use of the solution for 2 minutes. It was possible to verify significant alteration in surface roughness of the composite influenced by ethylic alcohol. It was not significant for distilled water and the mouthrinses.

Efek perendaman rebusan Daun Sirih Merah (Piper crocatum) terhadap kekerasan permukaan resin komposit

“…Resin komposit nano ller memberikan pengerutan yang lebih kecil, serta resisten dan retensi yang lebih besar dibandingkan jenis resin komposit lain. 5 Hal-hal yang perlu dipertimbangkan dalam pemilihan jenis resin komposit, salah satunya adalah sifat mekanik yaitu kekerasan permukaan yang dapat mempengaruhi ketahanan restorasi resin komposit. 5 Kekerasan permukaan resin komposit adalah ketahanan permukaan dari bahan resin komposit terhadap tekanan yang diberikan.…”

“…5 Hal-hal yang perlu dipertimbangkan dalam pemilihan jenis resin komposit, salah satunya adalah sifat mekanik yaitu kekerasan permukaan yang dapat mempengaruhi ketahanan restorasi resin komposit. 5 Kekerasan permukaan resin komposit adalah ketahanan permukaan dari bahan resin komposit terhadap tekanan yang diberikan. Adanya faktor yang mempengaruhi kekerasan resin komposit akan menyebabkan resin tersebut tidak tahan lama pada rongga mulut.…”

“…Salah satu faktor yang mempengaruhi penurunan ketahanan resin komposit adalah derajat keasaman (pH). 5 Hasil penelitian Kanan dkk (2012) menunjukkan bahwa degradasi resin komposit tidak hanya disebabkan kandungan alkohol pada obat kumur, tetapi juga pH dan kandungan kimia lain obat kumur. Hal ini menyebabkan terjadinya penurunan kekerasan permukaan resin.…”

Chemical and morphological features of nanofilled composite resin: Influence of finishing and polishing procedures and fluoride solutions

“…Mouthwash solutions have an effect on some properties of esthetic restorative materials such as color, hardness, and surface roughness (Celik et al,2008; Diab et al,2007; Gürdal et al,2002; Rocha et al,2010; Sadaghiani et al,2007; Yap et al,2003). These products contain different percentages of alcohol and other ingredients such as detergents, emulsifiers, organic acids, dyes, and solvents (Garcia et al,2002), which can cause degradation and surface softening of the resin matrix, promote the wear of the material and change the color of composite resin (Settembrini et al,1995).…”

Rugosidade superficial e microdureza de materiais restauradores provisórios submetidos a ação de enxaguatórios bucais

“…As características de superfície, como rugosidade superficial, do dente ou do material restaurador e microdureza (Anusavice et al, 2012), desempenham um papel fundamental para a longevidade das restaurações provisórias (Rocha et al, 2010), pois a biodegradação superficial resultante de soluções químicas, como enxaguatórios bucais, pode afetar as propriedades dos materiais (Sadaghiani et al, 2007;Voltarelli et al, 2010;De Paula et al, 2011;Padovani et al, 2014).…”
