The inhibition of polymerization of polyvinyl siloxane impression materials by direct contact with latex gloves has been well documented. Indirect intraoral inhibition of polymerization that results from contact of oral tissues with latex gloves during tooth preparation and gingival retraction procedures has been reported. This case report illustrates the problems that can occur when the dentist used polyvinyl siloxane impression materials while wearing latex gloves. In the reported case, the inhibition is severe and obvious; in most situations the inhibition of polymerization is more subtle and is frequently undetected. Clinicians must be aware of this potential problem and the solution to it.
聚甲基乙烯基硅氧烷印模材料与乳胶手套直接接触会抑制其聚合，这一点已有充分文献记载。有报告称，在牙体预备和牙龈退缩操作过程中，口腔组织与乳胶手套接触会导致聚甲基乙烯基硅氧烷印模材料在口腔内间接抑制聚合。本病例报告说明了牙医戴乳胶手套使用聚甲基乙烯基硅氧烷印模材料时可能出现的问题。在报告的病例中，抑制作用严重且明显；在大多数情况下，聚合抑制更为细微，常常未被察觉。临床医生必须意识到这一潜在问题及其解决办法。
