Abstract
결 론
저자는 생후 약1 년된 성견에서 formocresol, glutaraldehyde의 치수절단면의 접촉시간을
1분, 3분, 5분, 3일, 7일로 나누어 통법에 따라 치수절단술을 시행한 후 치수조직의 변화를
병리조직학적으로 관찰한 바 다음과 같은 결론을 얻었다.
1. Formocresol 1분, 3분, 3일, 7일군과 glutaraldehyde 1분, 3일, 7일군의 치수반응은 정상
치수소견으로부터 전반적인 응고성 괴사까지 다양하게 나타났다.
2. Formocresol 5분군과 g1utaraldehy-de 3분, 5분군은 다른군에 비하여 염증이 경미하였
으며 거의 정상적인 치수형태를 보였다.
3. Formocresol 군과 glutaraldehyde군에서 대부분 수복상아질이 형성되었다.
4. 상아질 흡수는 glutaraldehyde 군보다 formocresol 군에서 더 자주 관찰되었다.
#초록#
The purpose of this study is to observe tile histopathological changes of the pulp
tissue after vital pulpotomy with fornlocresol or glutaraldehyde at the different time
intervals of application. Upper and lower teeth in seven dogs, aged about 1 years, were
subjected to pulp amputations and were divided into two groups, one of which was
pulpotonlized with formocresol, the other was with glutaraldehyde, The application was
perfornled at the intervals of 1 mlnute, 3 minutes, 5 minites, 3 days and 7 days, and
then the experimental animals were sacrificed 2 months after the last experiment.
The excised jaw bones were fixed in 10% neutral buffered fornlalin solutions, and
they were routinely decalcified in 5% nitric acid, and embedded in paraffin, and sections
were stained with henlatoxylin and rosin and observed with light microscope.
Following results were obtained .
1. In the formocresol 1 minute-, 3 minute-, 3 day- and 7 day- groups and the
glutaraldehyde 1 minute-, 3 day- and 7 day- groups, the pulp tissue responses varied
from normal pulp tissue findings to total coagulation necrosis.
2. In the formocresol 5 minute- group and the glutaraldehyde 3 minute- and 5
minute-groups, they showed slight inflamation and the almost typical morphology of
normal pulp tissue.
3. In the almost formocresol and glutaraldehyde groups, reparative dentin was formed.
4. Dentinal resorption in the formocresol group was more frequent than that in the
glutar-aldehyde group.
