Objective: Height of the palate more than 2 SD above the mean
Subjective: Palatal height at the level of the first permanent molar more than twice the height of the teeth
The measuring device for this assessment is described in Hall et al. . A high palate is often associated with a narrow palate. However, a narrow palate can easily give a false appearance of a high palate. Height and width of the palate should be assessed and coded separately. We do not recommend the subjective determination because this term can be overused and applied inaccurately.
