Histological and immunohistochemical techniques were performed, as was histomorphometric analysis.ResultsIn the current study, we found that the density and size of cells were higher in the superficial papillary layer, whereas the thickness of the collagen bundles increased in the reticular layer. Excluding the epithelium, the mean percentage of lamina propria (LP) and submucosa (SM) was 37% and 63%, respectively (p < .001). LP thickness showed similar values in the incisal, premolar and molar regions, and a significantly greater thickness in tuberosity (p < .001). The thickness of SM increased from incisal to premolar and molar, disappearing in the tuberosity (p < .001).ConclusionsAs dense connective tissue of LP is the tissue of choice for connective tissue grafts, the best donor site from a histological point of view is tuberosity because it is composed only of a thick LP without the presence of a loose submucosal layer PB Wiley SN 0303-6979 YR 2023 FD 2023 LK http://hdl.handle.net/10347/30773 UL http://hdl.handle.net/10347/30773 LA eng NO García-Caballero, L., Gándara, M., Cepeda-Emiliani, A., Gallego, R., Gude, F., Suárez-Quintanilla, J., Ramos-Barbosa, I., & Blanco-Carrion, J.
