OBJECTIVE
This study aimed to evaluate the validity of using of digital dental X-ray for the thumb region in assessment of skeletal maturation stage around functional orthodontic treatment time.
MATERIALS AND METHODS
The sample consisted of 200 patients (100 males and 100 females) aged between (9.5-18) years. Each patient underwent a hand-wrist radiograph and a digital radiograph for the thumb region taken by a dental X-ray machine. Skeletal changes were studied in the sesamoid bone and first Metacarpophalangeal joint region, and compared to Björk method.
RESULTS
Good correlation was noted between our thumb method stages (Th index) and hand-wrist maturation stages, so Th index has a good validity and reliability in assessment of maturation stages, in addition to its simplicity, accuracy and advantages in saving time, cost and decreasing radiographic exposure compared with hand-wrist maturation stages.
目的
本研究旨在评估在功能性正畸治疗时间前后，使用数字化牙科X线片对拇指区域进行骨骼成熟阶段评估的有效性。
材料与方法
样本包括200名年龄在9.5至18岁之间的患者（100名男性和100名女性）。每位患者均接受了手腕部X线片检查以及由牙科X线机拍摄的拇指区域数字化X线片检查。对籽骨和第一掌指关节区域的骨骼变化进行了研究，并与比约克方法进行了比较。
结果
我们的拇指方法阶段（Th指数）与手腕部成熟阶段之间存在良好的相关性，因此Th指数在评估成熟阶段方面具有良好的有效性和可靠性，此外，与手腕部成熟阶段相比，它还具有简单、准确以及节省时间、成本和减少辐射暴露的优点。
