Autry Technology Center dental and medical assistant students and instructors help with the Oklahoma Mission of Mercy equipment set up at the Chisholm Trail Expo Center Thursday, Feb. 6, 2014. Due to the frigid temperatures, clients will be able to enter the Pavilion beginning at 5 p.m. this afternoon instead of waiting in line outside the Expo Center. Following an opening ceremony, free dental care will begin on more than 100 patients at a time during the two-day event. More than 2000 volunteers will assist. (Staff Photo by BONNIE VCULEK)
