“…As alternative to latex, chain elastics of types different as polyurethane and latex-free has been manufactured, in order to decrease the risk of allergic reactions caused by latex orthodontic elastics, as swelling and stomatitits, erythematous oral lesions, respiratory reactions, and even anaphylactic shock, the most severe form of allergy [3,4], can be cited.…”

“…But little is known if polyurethane and latex-free orthodontic ligatures are cytotoxic to oral mucosal cells [1][2][3][4][5][6]. Cell lines [7], such as L929 mouse fibroblasts [8], have been shown to behave similarly to primary human gingival fibroblasts and, therefore, are a suitable in-vitro model to test the toxicity [9][10][11][12] of products used intra-orally during orthodontic treatment [13][14][15].…”

Allergy caused by latex proteins has been well documented. Thus, the study of non-latex materials, is necessary. The aim of this study is to evaluate the cytotoxicity of silver-coloured orthodontic chain elastics, of polyurethane and latex-free. Nine chain elastics from different manufactures (3 latex-free and 6 polyurethane) were divided into 9 groups of 10 elastics each: Group UK (Latex-free, 3M Unitek), Group TP (Látex-free, TP Orthodontics), Group AO (Látex-free, American Orthodontics), Group O (Polyurethane, OrthoSource), Group M (Polyurethane, Morelli), Group TD (Polyurethane, Tecnident), Group UD (Polyurethane, Uniden), Group AZ (Polyurethane, Abzil) and Group AK (Polyurethane, Aditek). The cytotoxicity essay was performed using cell cultures (L-929 line cells, mouse fibroblast) that were submitted to the cell viability test with neutral red ("dye-uptake") at 1, 2, 3, 7 and 28 days. Analysis of variance (ANOVA) with multiple comparisons and Tukey's test were employed (p<.05). The results showed no statistically significant differences between Groups UK, TP and AO in all experimental times (p>.05), except between the Groups UK and TP at 28 days (p<.05). There was significant statistically difference (p<.05) between the viability of the cells in the Groups O and TD with the Groups M, AZ, AK at 1 and 2 days. The polyurethane elastics showed lower cell viability in the first 48 hours, with increase on 3rd and 7th day, and viability similar to latex-free elastics at 28 days. It can be concluded that the latex-free chain elastic showed higher cell viability. The OrthoSource and Tecnident trademark showed lower cell viability the initial 48 hours.

The aim of this study is to evaluate cytotoxicity between polyurethane and non-latex orthodontic elastomeric ligatures. Seven elastomeric ligatures of black-coloured from different manufactures (3 non-latex, 3 polyurethane and 1 latex) were divided into 7 groups of 10 elastics each: Group UK (nonlatex, 3M Unitek), Group TP (nonlatex, TP Orthodontics), Group AO (nonlatex, American Orthodontics), Group O (Polyurethane, OrthoSource), Group M (Polyurethane, Morelli), Group TD (Polyurethane, Tecnident) and Group TC (latexControl, TP Orthodontics). The cytotoxicity essay was performed using cell cultures (L-929 line cells, mouse fibroblast) that were submitted to the cell viability test with neutral red ("dye-uptake") at 1, 2, 3, 7 and 28 days. Analysis of variance (ANOVA) with 1-way analysis followed by the Tukey post hoc test were employed (p<.05). The results showed no statistically significant differences between Groups UK, TP and AO in all experimental times (p>.05). There was a statistically differences (p<.05) between the viability cell of Groups UK, TP and AO with the Groups O, M, TD and TC at 1, 2, 3 and 7 days. There was no statistically differences (p>.05) between the groups O, M and TD at in all experimental times. It can be concluded that the nonlatex elastomeric ligatures of Unitek, TP Orthodontics, and American Orthodontics showed higher cell viability compared to others ligatures.

Hypothesis: That water leakage rates and protection against blood-borne pathogens should not vary as a function of latex content among Food and Drug Administration-approved gloves, allowing avoidance of unnecessary latex exposure.Design and Methods: Eighteen different glove types were purchased and tested using the American Society for Testing Methods Standard Test for Detecting Holes in medical gloves, which involves mounting the glove on a plastic tube, pouring a liter of tap water into the glove, and visually inspecting the glove initially and after 2 minutes. Half of the gloves were tested straight from the package and half after a standardized manipulation.Setting: A university hospital.Results: Eleven sterile glove types (5 high latex content, 4 low latex content, and 2 nonlatex content), and 7 nonsterile examination glove types (2 high latex content, 2 low latex content, and 3 nonlatex content) were
