What is the normal width of keratinized gingival tissue on the buccal surface of the mandible?

The normal width of keratinized gingival tissue on the buccal surface of the mandible is typically recognized as being in the range of 3-4 mm. This measurement is significant in dental and periodontal assessments, as keratinized tissue plays an essential role in the health of the gingiva and the overall periodontal structure. Adequate keratinized tissue provides a protective barrier against mechanical trauma, helps to withstand forces from mastication, and supports the attachment of the gingiva to the underlying bone.

Maintaining a proper width of keratinized tissue is crucial for periodontal health, as insufficient keratinized tissue may lead to higher susceptibility to inflammation and other periodontal diseases. In contrast, widths outside of this optimal range may indicate pathological conditions or varying anatomical presentations, which could require further evaluation and potential intervention. Understanding these measurements assists clinicians in making informed decisions about periodontal treatment and patient care.
