Abstract

結論
서울대학교 병원 치과 진료부 소아치과에 내원한 아동 중 mesiodens를 지닌 3세에서 12
세 2개월 사이의 아동 57명을 대상으로 인상적 및 방사선학적 관찰을 한 결과 다음과 같은
결론을 얻었다.
1 정중 과잉치는 여자보다 남자에서, 하악보다 상악에서 호발하였다.
2. 구강내로 맹출한 정중 과잉치는 53.1%였으며, 75.3%가 정위상태였다.
3. 정중 과잉치의 형태는 원추형 56.8% 원주형 17.3%, 결절형 14.8%, 절치양상 6.2%, 견
치양상 4.9%였다.
4. 정중 과잉치로 인한 계발증 및 인접치아와의 관계에 있어서 48.2%가 특이할 만한 영향
이 없었고, 인접치 맹출지연 16.5 %, 치관회전이 11.8%, 정중이개 10.5%, 인접치의 치축경사
4.7%, 치근홉수 3.5%, crowding 2.4%, 인접치의 치근 발육저해 2.4 %였고, 과잉치로 인한
병소는 없었다.
#초록#
The author investigated clinically and radiographically the 57 children, who have
mesiodens, aging from 3 years to 12 years 2 months among the children who had
visited the Dept. of Pedodontics, Seoul National University Hospital.
The following results were obtained.
1. The mesiodentes were more frequent in male than in maxilla, and more freguent in
maxilla than in mandible.
2. The mesiodentes which erupted into oral cavity were 53.1 percent, and upright
mesiodentes were 75.3 percent.
3. The shapes of mesiodentes were as follows:
Conical shape was 56.8 percent, round shape was 17.3 percent, tuberculated shape was
14. 8 percent, incisor-like shape was 6,2 percent, and canine-like shape was 4.9 percent.
4. The relationship between mesiodentes and neighboring teeth and the complications
which mesiodentes caused were as follows: non-specific influence was 48.2 percent,
delayed eruption of neighboring tooth was 16.5 percent, crown mtatien of neigtlboring
tooth was 11.8 percent, median diastema was 10.5 percent, angulation of neighboring
tooth axis was 3.5 percent, crowding of neighboring tooth was 2.4 percent, root
underdevelopment of nei호boring tooth was 2.4 percent, and the associated lesion with
mesiodens did net exist.
