OBJECTIVES
To compare the cephalometric characteristics of thalassemic children in the Indian subcontinent with the controls, matched for sex and dental age.
METHODOLOGY
A total of 31 thalassemic children were a part of the study. Cephalometric readings were recorded for the study and the control group.
RESULTS
Within the Group I stage, the anterior cranial base length was 68.40±2.93 mm, shorter when compared to the control group. In the Group II stage, the maxillary/mandibular angle was 31.58° for the case group and the mandibular length was shorter in comparison to the controls. In the Group III stage, the SNB angle was 76.42°, lesser than the control group. A relative maxillary prognathism of 9.88 mm and 12.85 mm was observed in thalassemic males and females respectively through the Wiley's analysis.
CONCLUSION
The overall picture depicted a retruded position of the maxilla and a retrognathic mandible within the study group. A class II profile has also been observed among the study subjects.
目的
比较印度次大陆地中海贫血儿童与按性别和牙龄匹配的对照组的头影测量特征。
方法
共有31名地中海贫血儿童参与本研究。记录了研究组和对照组的头影测量读数。
结果
在第一阶段，前颅底长度为68.40±2.93毫米，与对照组相比更短。在第二阶段，病例组的上颌/下颌角为31.58°，下颌长度比对照组短。在第三阶段，SNB角为76.42°，小于对照组。通过威利分析，地中海贫血男性和女性分别观察到相对上颌前突9.88毫米和12.85毫米。
结论
总体情况显示研究组上颌后缩和下颌后缩。在研究对象中也观察到二类面型。
