In this study, we aimed to develop dental charts for Turkish children and young adults of both genders within the age group of 4.5-22.5 years according to tooth mineralization and eruption in a format similar to that proposed by AlQahtani et al.
In total, 753 digital panoramic radiographs from 350 males and 403 females were assessed. The permanent teeth were evaluated according to the classification system described by Demirjian et al. The eruption stage was assessed with Bengston's system, which was modified by AlQahtani et al at four points.
Teeth generally developed earlier in females than in males. This was particularly notable in the age group of 5-14 years. However, this difference was usually visible in only one stage, not in all teeth. It has been determined that the mixed dentition period ended with the shedding of the second deciduous molars in both genders.
The dental charts presented here included information that could be beneficial to dental clinicians in making appropriate diagnosis and planning orthodontic and surgical procedures. These charts also provided datasets for preliminary dental age estimation in Turkish children and young adults.
在本研究中，我们旨在按照与AlQahtani等人提出的格式类似的方式，根据牙齿矿化和萌出情况，为年龄在4.5 - 22.5岁的土耳其男女儿童及年轻成年人制定牙龄图表。
共评估了来自350名男性和403名女性的753张数字化全景X线片。根据Demirjian等人描述的分类系统对恒牙进行评估。萌出阶段采用经AlQahtani等人在四个点修改后的Bengston系统进行评估。
牙齿通常在女性中比在男性中发育得更早。这在5 - 14岁年龄组中尤为明显。然而，这种差异通常仅在一个阶段可见，并非在所有牙齿中都可见。已确定在男女中，混合牙列期均随着第二乳磨牙的脱落而结束。
此处呈现的牙龄图表包含的信息可能有助于牙科临床医生进行适当的诊断以及规划正畸和外科手术。这些图表还为土耳其儿童及年轻成年人的初步牙龄估计提供了数据集。
