Avaliação da citotoxicidade de elásticos ortodônticos intermaxilares

Abstract: RESUMOO objetivo do presente trabalho é avaliar a citotoxicidade de quatro diferentes marcas comerciais de elásticos inter-maxilares intra-orais. Foram avaliados elásticos da American Orthodontics (Grupo 1), 3M Unitek (Grupo 2), Morelli (Grupo3) e Uniden (Grupo 4). Os elásticos foram previamente esterilizados em luz ultravioleta e colocados em placas de Petri, as quais continham cultura de células HEp-2., Após 24 h, as monocamadas de células foram coradas e, em seguida, realizada uma avaliação dos halos de dif… Show more

“…Another point to be discussed is the quality of the orthodontic elastic band, which ideally must be radiopaque, allowing its detection in the radiographic exam. In addition, it might be also nontoxic, reducing the tissue adverse reaction [ 23 ]. However, this type of material is often illegally marketed, not following quality standards.…”

“…A utilização de diversas composições para a fabricação de elásticos ortodônticos também podem provocar diferentes reações biológicas aos tecidos bucais. Assim, é importante que fatores como a citotoxidade dos mesmos seja avaliada, evitando riscos ao paciente (PITHON et al, 2008;PITHON et al, 2008).…”
