To establish reference data for anterior and posterior dentoalveolar heights of growing French-Canadians with untreated normal occlusions and malocclusions.
The mixed longitudinal sample includes 227 French-Canadians, 119 male and 108 female, with cephalograms taken annually between 10-15 years of age. Maxillary and mandibular dentoalveolar heights were measured as the perpendicular distances of the incisor tips and first molar mesial cusp tips to the palatal (ANS-PNS) and mandibular (Go-Me) planes.
Male dentoalveolar heights were significantly (P < .05) greater than female heights at all ages. Dentoalveolar heights at 15 years of age were significantly larger (P < .05) than at 10 years of age, with differences ranging from 2.1-4.2 mm in male subjects and from 2.1-3.8 mm in female subjects. The greatest difference in dentoalveolar heights between the 10- and 15-year-old age groups was for the maxillary first molar; the maxillary central incisor height showed the smallest age effects. The coefficients of variation were greater for the maxillary than the mandibular dentoalveolar heights. Correlations of dentoalveolar heights within jaws ranged from 0.53 to 0.82; correlations between jaws ranged from 0.30 to 0.44. The mandibular heights showed the strongest associations.
French-Canadian adolescents require age- and sex-specific reference data for dentoalveolar heights.
为未治疗的正常咬合和错颌畸形的生长发育阶段法裔加拿大人建立牙槽前后高度的参考数据。
混合纵向样本包括227名法裔加拿大人，其中男性119名，女性108名，在10至15岁期间每年拍摄头颅侧位片。上颌和下颌牙槽高度测量为切牙切端和第一磨牙近中尖到腭平面（前鼻棘-后鼻棘）和下颌平面（下颌角点-颏下点）的垂直距离。
在所有年龄段，男性牙槽高度均显著高于女性（P < 0.05）。15岁时的牙槽高度显著大于10岁时（P < 0.05），男性受试者的差异范围为2.1 - 4.2毫米，女性受试者为2.1 - 3.8毫米。10岁和15岁年龄组之间牙槽高度差异最大的是上颌第一磨牙；上颌中切牙高度的年龄效应最小。上颌牙槽高度的变异系数大于下颌。颌内牙槽高度的相关性范围为0.53至0.82；颌间相关性范围为0.30至0.44。下颌高度显示出最强的相关性。
法裔加拿大青少年需要针对年龄和性别的牙槽高度参考数据。
