The palate plays a crucial role in oral functions such as speech, breathing, and mastication. Understanding its development during growth is essential for diagnosis and treatment planning. This study aimed to assess changes in palatal depth, width, volume, and surface area at ages 8, 12, and 18.
This retrospective analysis of palatal characteristics was performed on dental casts obtained at 3 time points: 8, 12, and 18 years of age from untreated cases obtained from the Forsyth Twin Growth Study database collected from 1959-1975. The casts were scanned then eleven landmarks were plotted and a 3D analysis was performed to obtain the anterior and posterior widths and depths, surface area, and volume. Repeated measures ANOVA and posthoc Bonferroni's test were performed to evaluate the changes at different ages.
Thirty subjects (16 females and 14 males) were included in this study. There was a statistically significant increase in volume and posterior depth among all age groups for both sexes. Surface area exhibited early growth from age 8 to 12 in males, plateauing after 12 years, while anterior depth significantly increased from ages 12 to 18 in both sexes. Anterior width grew significantly in females during the same period, with no significant changes in males. Posterior width showed a gradual increase with no significant difference between 8 and 12 years or 12 and 18 years.
There were consistent incremental changes in the palate's volume and posterior depth. The anterior width of the palate did not show consistent growth, as it only significantly increased dimensions from 12 to 18 years of age in females, whereas the surface area plateaued in males after 12 years, and posterior width changes were non-significant.
腭在言语、呼吸和咀嚼等口腔功能中起着至关重要的作用。了解其在生长过程中的发育情况对于诊断和治疗计划至关重要。本研究旨在评估8岁、12岁和18岁时腭的深度、宽度、体积和表面积的变化。
对从1959年至1975年收集的福赛思双生子生长研究数据库中获取的未经治疗病例的牙模进行了腭部特征的回顾性分析。这些牙模在8岁、12岁和18岁这三个时间点获取。对牙模进行扫描，然后绘制11个地标点，并进行三维分析以获得前后宽度和深度、表面积和体积。采用重复测量方差分析和事后邦费罗尼检验来评估不同年龄的变化。
本研究纳入了30名受试者（16名女性和14名男性）。所有年龄组的男性和女性的体积和后深度均有统计学上的显著增加。男性的表面积在8岁至12岁时早期生长，12岁后趋于平稳，而两性的前深度在12岁至18岁时显著增加。在此期间，女性的前宽度显著增加，男性则无显著变化。后宽度逐渐增加，8岁至12岁或12岁至18岁之间无显著差异。
腭的体积和后深度有持续的增量变化。腭的前宽度没有呈现出一致增长趋势，因为仅在女性12岁至18岁时尺寸显著增加，而男性的表面积在12岁后趋于平稳，后宽度变化不显著。
