Acrylic resin being has been used in dentistry since 1946. Apple vinegar solution currently popular as healthy supplement drink. It consists of tanin (fenol), acid, and other subtances. Fenol and acid are able to chemically damage to acrylic resin. The purpose of this study was to investigate the impact strength of heat cured acrylic resin after immersed in apple vinegar solution. This experiment was carried out on the heat cured acrylic resin sample of size 65 x 10 x 2.5 mm. The immersion periods varied from 45 minutes, 11 days, and 17 days. There were 42 samples, divided into 21 samples for three treatment groups and 21 samples for three control groups. The result showed that there were significant differences of acrylic resin strength after immersion in apple vinegar at 45 minutes and 17 days. The conclusion was the longer immersion time of acrylic resin in apple vinegar would reduce the impact strength.
