Influence of a Fluoridated Medium with Different pHs on Commercially Pure Titanium‐Based Implants

Abstract

It was possible to conclude that both the fluoride concentration and the pH of the solutions did not exert any influence upon implant corrosion resistance.

Titanium surface topography after brushing with fluoride and fluoride-free toothpaste simulating 10 years of use

“…Discrepancies may be due to the different methodologies since the first authors performed manually brushing, whilst the other used electric toothbrushes with rotating oscillation, with lower abrasion power. 25 Available data suggest that changes on 3D AFM surface topography, Ra values and SEM micrographs in titanium immersion tests, were associated with higher fluoride concentrations and/or acidic NaF solutions, 3,8,11,12,14,18 likely because of the reactions that occur with the NaF and the protective oxide layer. When NaF agents are in contact with titanium, sodium and fluorides ions are released.…”

“…These results may have been driven by the low concentration of fluoride and by the pH value. 8,9,13,15,18,26 In this study, fluoride toothpaste with 1500 ppm F À and pH = 6.3 was used. According to Nakagawa et al 9,13,15 titanium changes induced by fluoride can be predicted by pH and fluoride concentration.…”

“…17 Most studies focused on the chemical effects of fluoride, by submerging titanium in fluoride solutions. 1,3,6,8,12,16,18 In real life, however, removable prosthesis, implanted supported structures, brackets and orthodontic wires must be daily cleaned by brushing. The effects of this procedure on the titanium surface are not conclusive, 2,14,19-21 with a single study focusing on the relationship between the chemical actions of fluoride and the mechanical actions of toothbrushing using toothpastes.…”

Shear Bond Strength Comparison between Conventional Dental Nano Zirconia Combinations and New Functionally Graded Nano Zirconia Combinations after Thermal-Mechanical Cycling

“…In the present study, the number of cycles was set as 25,000, 50,000 and 100,000. Sartori [10] xed a number of 100,000 mechanical cyclic testing for dental implants, thus estimating a 5 year period in the oral cavity. Mechanical cycles of 25,000 and 50,000 cycles were therefore equal to 1.25 and 2.5 years of clinical service, respectively.…”

Avaliação de massa e rugosidade superficial de pastilhas de Ti-6Al-4V com aplicação de nanopartículas de prata submetidos ao teste de escovação

“…A ação mecânica dos abrasivos dos dentifrícios juntamente com a ação das cerdas das escovas foi responsável pela variação da rugosidade dos espécimes, também observada por outros autores (HOSSAIN et al, 2006(HOSSAIN et al, ,2007FAIS et al,2012;SIIRILÄ E KÖNÖNEM, 1991;SALLES et al, 2009 MAYOUF et al, 2004;SARTORI et al, 2009;TONIOLLO et al, 2009;MABILLEAU et al, 2006;POPA et al, 2008;LEE, 2005) e/ou o biofilme específico (ZHANG et al, 2013;SOUZA et al, 2010).…”
