The Wall Street Journal's MarketWatch wire service recently featured research presented at Frontiers in Oral Medicine, the Academy's most recent annual meeting. 

"The poster, entitled "Effectiveness of a Polymer-Based Muco-Adhesive (MuGard®) in the Healing of Oral Ulcers in Erosive Lichen Planus: A Pilot Study" reflected results of a randomized, doubled-blinded study (1:1 randomization into MuGard® or bicarbonate rinse arm) of 20 patients with biopsy proven oral lichen planus. Patients in the MuGard® arm had statistically significant improvement in ulcerations and pain, and the changes in pain were closely related to the health of the ulcers. There was no statistically significant change in erythema."
