Macroscopically, the dental organ appears to be limited to the dental crown surrounded by soft tissue, which is scalloped around a well delineated circular line called the cementoenamel junction (CEJ). The morphology of the dental crowns change shape from the midline to the posterior dentition and with it, the function and dimension change. The soft tissue changes as well to accommodate these differences. That soft tissue will comprise two distinct parts, the mucosa and the keratinized tissue separated by the mucogingival line (MGL). In the keratinized zone, we have the attached gingiva and the marginal gingiva. The latter is a non-attached tissue that extends few millimeters from the margin to the junctional epithelium (JE), delineating the sulcus that is a gap on the inner side of the non-attached gingiva around the CEJ. JE is non-keratinized epithelium as it is on the border of the attached and non-attached gingiva.
