Streptococcus mutans adhesion and releasing of metallic ions in dental alloys

Abstract

Aim: To evaluate the adherence of Streptococcus mutans to the surface of the amalgam and copper/aluminum alloy samples and also evaluate the release of metallic ions. Methods: The prepared medium was changed every 72 h and analyzed by atomic absorption spectrophotometer. Samples were removed from the prepared medium at 15, 30, 48 and 60 days. Results: The result shows that ions released were statistically different among all groups, and so were both biofilm and pits formation and the corrosion induced by the S. mutans in both types of samples. SEM observation of the samples immersed in the prepared medium with S. mutans showed adherence of microorganisms on the whole surface, in all groups. Conclusions: The S. mutans adhere to both amalgam and copper/aluminum alloy causing corrosion of those restorations. S. mutans produced a greater ions release in Cu/Al alloy; in amalgam, the ions release was not influenced by exposure to S. mutans.

Reabilitação estética anterior com sistema IPS e.max: relato de caso

“…A periodontia é uma área de estreita relação com a prótese fixa, pois vários fatores estão relacionados à saúde periodontal, como forma, contorno, higiene oral e localização da margem cervical do preparo 3 . A inflamação periodontal ocorre através do acúmulo de biofilme na margem gengival, então é necessário o condicionamento periodontal antes da instalação das próteses definitivas, para que não se instale doenças periodontais e ocorra infiltrações que levarão ao insucesso da reabilitação 21 . A reabilitação estética descrita neste relato, fundamentada no diagnóstico, planejamento e execução com uso do sistema IPS e.max ZirPress proporcionou um resultado estético e funcional satisfatório, atendendo as expectativas da paciente.…”
