目的：探讨不同品种手套或表面活性剂间接接触硅橡胶印模材料后，对其阻聚作用的影响。方法：两种手套（有粉和无粉）、4种表面活性剂处理（自来水，肥皂水，酒精，对照）、温度（22°C和36°C）共3个独立变量，组合成16个实验组。不同品种手套与表面活性剂接触后，与干净的玻璃板摩擦，空气吹干。加聚型硅橡胶材料混合于处理的玻璃板上，按照聚合时间要求，再取下样本，判断是否阻聚，材料残留于玻璃板上为阻聚。采用x2检验进行比较。结果：阻聚仅发生在手套／酒精组。22°C温度下，阻聚在90％～95％，36°C温度下，阻聚为55％～65％。结论：乳胶手套与硅橡胶印模材料接触，不会发生阻聚，但是一旦与酒精接触，阻聚现象特别明显。

Objective:To examine the polymerization inhibition of polyvinylsiloxane impression materialplaced in con-tact with surfaces subjected to prior contact with gloves or commonly used surfactants at different temperatures. Method:A 2×4×2 design was used (n=16),with 2 types of gloves (powdered and unpowdered),4 surfactant conditions (water,soap/water-rinse,alcohol,and control),and 2 ambient temperatures of 22 ° C and 36 ° C. After glove exposure to surfactants,a glass surface was subjected to rubbing contact with the treated glove for a standardized time. After drying,au-tomixed polyvinylsiloxane impression materials were dispensed onto the treated surface. Specimens were removed and evaluat-ed for polymerization inhibition at the manufacturer's recommended polymerization time. Specimens were rated as polymer-ized,or as inhibited if any polyvinylsiloxane residue remained on the slab. A chi-square analysis was used to evaluate the results. Result:Setting inhibition was found only with the polyvinylsiloxane material when alcohol was used as a surfactant. At 22 °C,the inhibition rate ranged from 90 % to 95 % for both glove types;at 36 °C,inhibition ranged from 55%(unpow-dered gloves) to 65%(powdered gloves), respectively. Conclusion:Under these in vitro conditions, glove exposure to alco-hol resulted in polymerization inhibition of tested polyvinylsiloxane impression material.
