Three dimensional measurements of the palate using the semiconductor laser 3. Changes in the palate section areas, palate projection areas and palate volumes in the early permanent dentition according to age

The objective of the study was to examine changes in palate section area, palate projection area and palate volume according to age. Using the maxillary dentition models, the palates of 10-, 12- and 14-year old children, who were in the early permanent dentition period, were measured threedimensionally using the semiconductor laser. Palate section areas between canines, the first premolars, second premolars and first molars became greater as children aged because the palate enlarged vertically with the growth and development of the maxilla. The palate projection area became greater as children aged because the palate enlarged laterally with the growth and development of the maxilla. The palate volume became greater as children aged because the palate enlarged laterally and vertically.
