The aim of this prospective split\u2010mouth clinical trial is to assess clinical, histological and patient outcomes following topical phenytoin (PHT) treatment of experimental palatal wounds.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Systemically healthy adults were recruited. One 6\u00a0mm diameter wound (posterior) and one 4\u00a0mm diameter wound (anterior), each 1\u20101.5\u00a0mm deep, were created on both sides of the palate. Wounds on one randomly chosen side received 10% phenytoin USP and contralateral wounds received carrier alone. Biopsies were harvested from anterior wounds (Day\u00a01 or Day\u00a05) and were routinely processed for histology. Posterior wounds were left undisturbed to clinically evaluate healing (using photographs and Healing Score Index) on Days\u00a01, 5, 14, and 21. Questionnaires were used to assess patient\u2010centered outcomes. Data analysis was performed using generalized logistic and generalized linear mixed models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Twenty participants completed all visits. 30% of participants reported more pain on control side than the PHT side at Day\u00a01 (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.014). PHT treated sites were more likely to not exhibit swelling (OR\u00a0=\u00a09.35; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.009) and to not experience pain on palpation (OR\u00a0=\u00a06.278; <jats:italic>P<\/jats:italic>\u00a0=\u00a00.007). PHT significantly and time\u2010dependently affected granulation tissue appearance (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.004). Histologically, there were no significant differences between control and PHT, at any time point (<jats:italic>P<\/jats:italic> \u2265
