Effect of Alkaline Peroxides on the Surface of Cobalt Chrome Alloy: An In Vitro Study

Abstract

The various solutions tested did not have any deleterious effects on the Co-Cr alloy surface. Steradent, however, presented the smallest ionic release.

Effect of Denture Cleansers on Cobalt‐Chromium Alloy Surface: A Simulated Period of 5 Years’ Use

“…The metal disks were randomly distributed in 5 experimental groups (n = 11) according to the cleanser solutions used (Fig ). Initial surface topography analysis and qualitative evaluation of the surface composition of the Co‐Cr alloy was performed on one specimen of each group by scanning electron microscopy (SEM) and energy dispersive X‐ray spectroscopy (EDS) and measurement of the surface roughness values (n = 10). The specimens were then placed in plastic containers with 150 mL of cleanser solution.…”

“…Chemical solutions have proven antimicrobial action and are effective in the removal of biofilm, having special importance in the remission of denture stomatitis . However, it has been reported that some cleansers promote adverse effects on the metallic surface, making them impracticable for use in RPD cleaning, since compatibility with the constituent materials of the denture is an important requirement for denture cleansers …”

“…Effervescent cleansing tablets are commonly indicated and, their use is often recommended in the literature . There are reports that they do not provide deleterious effects in relation to the hardness and surface roughness of the metal alloys, besides being effective in the removal of biofilm . However, although these compounds are indicated by manufacturers for denture cleaning, undesirable effects such as oxidation of the metal surface and release of ions have been found.…”

“…For complete dentures, castor oil ( Ricinus communis ) has been evaluated as a cleanser due to its antifungal and antibacterial characteristics, confirmed by studies related to endodontics . According to Pisani et al, R. communis can be seen as an alternative, inexpensive, and safe substance to be used by the population.…”

Reabilitação oral em paciente com síndrome da combinação: relato de caso / Oral rehabilitation in a patient with combination syndrome: a case report

“…No Brasil a ideia de que a perda dentária é um fenômeno natural que ocorre devido ao envelhecimento é aceito como fato cultural, porém é totalmente equivocada, pois isso se dá devido à falta de prevenção, informação e principalmente cuidados com a higiene oral que pode desencadear infecções locais ou sistêmicas (VASCONCELOS et al, 2019).…”
