A study reported results of a double-blind randomized clinical trial comparing tooth sensitivity for 14 patients using a fluoride gel to 15 patients using placebo. Each patient had weekly visits for responses, between 3 and 7 times. The authors reported a 2 x 2 table having counts (11, 57) for placebo and (21, 62) for fluoride gel for the (yes, no) response on tooth sensitivity.
