Abstract：
Background: Dermatoglyphics is the study of various dermal configurations on the fingers, palms, and soles. These appear during the 12th week of intrauterine life and develop completely by the 24th week. It is said that they remain constant thereafter. The aim of the present study was to compare and assess the association of dermatoglyphic patterns between skeletal class I and skeletal class III malocclusion. Methods: Finger and palm prints were collected using the ink and roller method from 604 subjects who were divided into skeletal class I, class III with maxillary retrognathism and class III with mandibular prognathism based on lateral cephalogram assessment. Results: Loop pattern was more predominant in skeletal class I malocclusion subjects and whorl pattern was more frequent in the other two groups. Total finger ridge count and atd angle also showed significant difference between the study groups. Conclusions: The present study attempted in assessing the association between dermatoglyphic patterns and skeletal malocclusion. Analysing dermal configurations may aid in indicating the type of developing malocclusion and thus help in interceptive and preventive orthodontics.
摘要：
背景：皮纹学是对手指上各种皮肤构型的研究，手掌,和鞋底。这些出现在子宫内生命的第12周，并在第24周完全发展。据说此后它们保持不变。本研究的目的是比较和评估骨骼I类和骨骼III类错牙合之间的皮纹模式的关联。方法:采用墨辊法采集604名骨骼Ⅰ类受试者的手指和掌纹,根据头颅侧位图评估，上颌下颌后突III类和下颌前突III类。结果：在I类骨骼错牙合患者中，环状模式更为明显，在其他两组中，螺纹模式更为常见。总指脊计数和atd角度也显示出研究组之间的显着差异。结论：本研究试图评估皮纹模式与骨骼错牙合之间的关联。分析真皮构型可能有助于指示发生错牙合的类型，从而有助于拦截和预防性正畸。
