This investigation sought to study the permeability of three commonly used clinical gloves when exposed to chemical agents.
A total of 35 gloves of each type were selected at random and were assigned to one of seven equally sized treatment groups. The effective barrier properties were investigated following treatment for 15 min with one of: acid etchant, Trim, cavity varnish, Hibiscrub, Hydrex and Vitremer using a dye permeability test. Following the chemical insult a 0.02% solution of erythrosine dye was introduced into each glove and the outer glove surface was washed with 10 ml of distilled water at intervals of 30, 60, 90 and 120 min. The percentage absorption of the collected washings, at 530 nm, was determined using a spectrophotometer. The results were compared with those values obtained from untreated gloves.
Acid etchant and Hydrex had little effect on any of the gloves. Trim caused an increase in permeability of the vinyl gloves but had little or no effect upon those made of latex. Cavity varnish increased the permeability of both Biogel D and Tru-Touch but had no effect on Featherlite. The integrity of the latex gloves was diminished by Hibiscrub but little effect was observed in the case of the vinyl based glove. The permeability of all three gloves was increased by exposure to Vitremer liquid.
Manufacturers should provide details of potential glove chemical interactions to assist dentists in glove selection.
本研究旨在探讨三种常用临床手套在接触化学试剂时的渗透性。
每种类型的手套随机选取35只，分为七个同等大小的治疗组之一。使用染料渗透性试验，用以下试剂之一处理15分钟后，研究其有效屏障性能：酸性蚀刻剂、Trim、窝洞封闭剂、洗必泰醇、Hydrex和Vitremer。化学损伤后，将0.02%的赤藓红染料溶液注入每只手套，并在30、60、90和120分钟的间隔用10毫升蒸馏水冲洗手套外表面。使用分光光度计测定收集的冲洗液在530纳米处的吸收百分比。将结果与未处理手套获得的值进行比较。
酸性蚀刻剂和Hydrex对任何手套的影响都很小。Trim使乙烯基手套的渗透性增加，但对乳胶手套的影响很小或没有影响。窝洞封闭剂增加了Biogel D和Tru-Touch的渗透性，但对Featherlite没有影响。洗必泰醇降低了乳胶手套的完整性，但对乙烯基手套的影响很小。所有三种手套接触Vitremer液体后渗透性均增加。
制造商应提供潜在的手套与化学物质相互作用的详细信息，以帮助牙医选择手套。
