University of California, School of Dentistry, San Francisco, Calif.1. issue-conditioning agents are used to improve the health of abused denture-bearing tissues’-3 and to make functional impressions for reline procedures.‘-lo For both of these uses, a uniform mix that incorporates minimal air in the tissue conditioner is desirable. The incorporation of air produces voids in the material, and voids are undesirable for several reasons. When the material is used as a tissue-conditioning agent, voids may harbor debris, bacteria,“,‘* and oral yeasts’3,‘4 that will further irritate the tissue. When the material is used to make functional impressions, voids can create inaccuracies in the impression.‘5Vacuum treatment of tissue-conditioning agents may offer a solution to the problem of voids in the material. Vacuum-mixing is widely used in dentistry to reduce the entrapment of air in gypsum produc@-‘* so the technology is available to most dentists. The purposes of this study were to determine (1) if vacuum treatment reduces void formation in tissue-conditioning agents and (2) if
