Abstract
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.关键词
