OBJECTIVES
To determine dental maturity (dental age) in cross-sectional sample of Saudi Arabian children by applying the standards established by Demirjian and Golstein and to examine the applicability of these standards in determination of dental maturity among Saudi Arabian children (Qassim region).
MATERIALS & METHODS: Dental maturity was assessed from panoramic radiographs of 400 Saudi Arabian children, 222 boys, and 198 girls ranging in age from 4 to 14 years by using these standards. The difference between the dental and chronological age in different age groups in both sexes was statistically compared using ANOVA testat 0.05 level of significance.
RESULTS
The Saudi Arabian children were generally somewhat advanced in dental maturity compared with the French Canadian reference sample with an overall mean difference between the dental and chronological age of 0.279 years in boys and 0.385 years in girls.
CONCLUSION
The applied standards appear to be adequate for studying dental age in groups of children among Saudi Arabian population.
目的
通过应用德米尔坚和戈尔斯坦制定的标准，确定沙特阿拉伯儿童横断面样本中的牙齿成熟度（牙龄），并检验这些标准在沙特阿拉伯儿童（卡西姆地区）牙齿成熟度测定中的适用性。
材料与方法
使用这些标准，从400名年龄在4至14岁的沙特阿拉伯儿童（222名男孩和198名女孩）的全景X光片中评估牙齿成熟度。使用方差分析在0.05显著性水平上对不同年龄组中男女的牙龄与实际年龄之间的差异进行统计学比较。
结果
与法裔加拿大参考样本相比，沙特阿拉伯儿童的牙齿成熟度总体上有所提前，男孩牙龄与实际年龄的总体平均差异为0.279岁，女孩为0.385岁。
结论
所应用的标准似乎足以用于研究沙特阿拉伯人群中儿童群体的牙龄。
