The ulcer size was measured on day 0, 2, 5, and 7. Two ulcer size parameters consisting of the pseudomembranous ulcer size and erythematous border size were measured. The ulcer diameters were measured using a calibrated dental probe with millimeter markings, and the ulcer sizes were calculated using formulas for the surface area of a circle or ellipse. The ulcers were photographed alongside a visual reference of known size, and a researcher drew the boundary of the pseudomembranous ulcer and erythematous border size on the captured image. The images were analyzed using computer software (Image-Pro Plus version 4.5 for Windows, Media Cybernetics, Rockville, MD, USA).
