The connective tissue graft: a comparative clinical evaluation of wound healing at the palatal donor site

Statistically significant differences were found between the SI and FGG techniques in terms of CE, which occurred faster in the SI group. The discomfort rate recorded for both SI and TD groups was significantly lower than for FGG group. No marked differences were noted between SI and TD procedures. The latter was confirmed by patient interviews. The results of this preliminary study have little statistical significance because of the limited number of patients but they represent an important basis for a comparative clinical study, with a larger sample of participants, which is currently in progress.
