Since a split-mouth design was not feasible and the defects being corrected by the mucosa particularly in the vestibular portion of the study are not usually symmetrical or bilateral, the use of paired subjects was not a reliable format. All the data were analyzed with IBM’s SPSS Statistics using ANOVA Repeated Measurements statistical method. Mean values for keratinized mucosal width and probing depth were recorded in millimeters at each examination time point and subsequently expressed in a percentage. First measurement for keratinized tissue, recorded immediately after surgery, was considered as 100%. Less than 20% of contraction was considered as excellent value, while good when less than 50%, fair to poor when higher than 50%, and unsatisfactory when the graft was lost.
