| Abstract: | The objective of the study was to examine changes in palate sectional areas, palate projection areas and palate volumes according to age. Using the maxillary dentition models, the palates of 7-, 8- and 9-year-old children, who were in the mixed dentition period, were measured threedimensionally using the semiconductor laser. The palate section areas, particularly between deciduous canines, primary first molars, primary second molars and first molars, increased with age, as the palate expanded vertically along with the growth and development of the maxilla. The palate projection areas increased with age, as the palate expanded laterally along with the growth and development of the maxilla. The palate volume increased with age, as the palate expanded laterally and vertically. |
