韓國人 混合齒列期 兒童 및 成人에 관한 頭部放射線學的 計測 = Roentagenographic Measurements of Korean Children and Adults

국문 초록 (Abstract)

正常咬合을 가진 混合齒列期 兒童(男子 55名, 女子 46名) 및 成人(男子 41名, 女子 36名)을 對象으로 側貌 頭部放射線規格寫眞上에서 坂本分析法에 의해 頭蓋顔面骨의 成長 變化를 觀察하여 다음과 같은 結論을 얻었다.
9才, 11才, 成人에서 男女別 各 計測項目의 平均値, 標準偏差 및 profilogram을 얻었다.
頭蓋顔面骨의 크기는 深度에서는 9, 11 才에서 男女間 有意差는 거의 나타나지 않았으나, 高徑은 9才에서 男子가 上顔面部 및 下顎部에서 더 크게 나타났으며 11才에서는 N, PTM, PNS를 제외한 全 項目에서 男子가 더 크게 나타났다. 成人에서는 深度에서 GO, 高涇에서 N을 제외한 金 項目에서 男子가 더 크게 나타났다.
9才에서 11才까지의 平均成長量은 上顎 中切齒 및 上下顎 第一大臼齒, 신부에서는 큰 것으로 나타났고 上顔面部, 上顎部에서는 비교적 작은 것으로 나타났으며, 頭蓋顔面骨의 전반적 成長은 S를 中心으로 하였을 때 下方性 長傾向이 優勢한 前下方成長을 하였다.

The purpose of this study was to investigate the growth change of craniofacial complex in korean children & adults.
The subjects included 55 males and 46 females in children, 41 males and 36 females in adults.
A series of 2 lateral cephalometric radiographs obtained from each child at age 9 and 11 and 1 lateral cephalometric radiograph obtained from each adult were analyzed by Sakamoto's coordinate system.
The conclusions were as follows :
Means, standard deviations and profilograms from measurements were obtained at age 9, 11 and adult.
Sexual difference in depth of craniofacial complex was hardly found at age 9 and 11, but in height male was larger than female in upper facial and mandibular portion at age 9 and in all of the items except N, PTM, PNS at age 11. At Adult male was larger than female in all of the items except Go in depth and N in height.
Growth increments of upper and lower incisors, upper and lower first molars and chin portion from age 9 to 11 were large, whereas those of upper facial and maxillary portions were relatively small, and the craniofacial complex grew forward and downward, but more downward.
