Comparative histological evaluation of intra- and extraorally de-epithelialized connective tissue graft samples harvested from the posterior palate region.

Although the intraoral method may provide several practical advantages compared with the extraoral technique, both approaches for de-epithelialization of CTG samples harvested from the posterior palate region tested in this study were comparably effective. However, none of these methods ensured complete removal of the oral epithelium in a predictable manner, which should be considered in clinical practice.
