Abstract

서울大學校病院小兒齒科에 來院한 滿 6歲에서 11歲까지의 兒童 122名(男69名, 女53名)의
上下左右永久中切齒 및 側切齒 854個에 있어서 electric pulp stimulator의 最大剌戟에 對한
齒髓反應을 各齒根發育段階에서 調査한 結果는 다음과 같다.
1. 齒根端이 completely open인 境遇, 陽性灰應은 13.1%, 陰性反應은 86.9%이였고, ⅔ open
인 境遇는 陽性反應이 33.1%, 陰性反應이 66.9%, ⅓ open인 境遇는 陽性反應이 57.8%, 陰性
反應이 42.2%이였고, closed인 境遇는 陽性反應이 80.0%, 陰性反應은 20.0%이였다.
2. 上下左右永久中切齒 및 下顎側切齒에서 各齒根發育段階에 따른 electric pulp
stimulator에 對한 齒髓反應은 齒根發育이 進行됨에 따라 各各陽性反應이 높아졌으나, 上顎
側切齒에서는 그렇치 않았다.
3. 各齒根發育段階에 따른 electric pulp stimulator에 對한 齒髓反應은 左右側同名齒牙間
과 上下顎同名齒牙間에서 各各有意한 差異를 認定할 수 없었다.
#초록#
The author studied the response to the stimulation of an electric pulp stimulator of
healthy 854 permanent anterior teeth in 122 children aged from six to eleven years old,
during different stages of tooth development.
The results were as followings :
1) In completely open apices, 13.1% (18 teeth) showed positive responses, and 86.9%
(120 teeth) showed negative responses. In two-thirds open apices 33.1%(75 teeth)
showed positive responses, and 66.9% (152 teeth) showed negative responses. In
one-third open apices 57.8% (118 teeth) showed positive responses, and 42.2% (86 teeth)
showed negative responses. In closed apices 80.0% (228 teeth) showed positive
responses, and 20.0% (57 teeth) showed negative responses.
2) The number of positive responses increased in each upper and lower central incisors
during the stages of root development, but not in upper lateral incisors.
3) There were no significant differences statistically in responses between the teeth of
the right and left sides and the upper and the lower jaw, in the same stages of root
development.
