Palate, Narrow

Definition:

Objective: Width of the palate more than 2 SD below the mean

Subjective: apparently decreased palatal width

Comments:

Palatal width is measured as the distance between the maxillary first permanent molar on the right and left sides, at the lingual cervical line, using a specific device. Palate width is typically assessed subjectively in routine clinical practice. Narrowing is often associated with a High palate, but this should be assessed and coded separately. Gingival overgrowth can give the impression of a narrow palate but should be distinguished and coded separately. The term "gothic palate" is used to indicate that the roof of the palate is not round but rather has an inverted V-shape, and therefore, only the upper part of the palate is narrow.
