Summary:

      This placebo-controlled, double-blinded, randomized crossover study evaluates the plaque and
      gingivitis reducing capacity of Cetylpyridium Chloride (CPC) chewing gum, with mechanical
      oral hygiene. The study will enroll 73 students, faculty, and staff from the UTHealth School
      of Dentistry. Half of the eligible participants will be randomly assigned to get the CPC gum
      in the first treatment period (21 days), a wash-out period of 21 days, and then a placebo gum
      in the second treatment period (21 days). The other half will be assigned to follow the same
      schedule but with the treatment reversed. A statistician will perform the randomization.
      Primary outcomes are assessed by validated tools, such as the Plaque Index (PI), Gingival
      Index (GI), and percent of bleeding sites on probe (BOP).
