Abstract
결론
저자는 평균체중 13.2㎏ 되는 개 5마리 75개 치아의 견치, 소구치, 구치의 협면에 5급와
동을 형성하여 치과용 가칠을 도포하지 않은 대조군과 불소함유 제품인
DuraphatR를 도포한 실험군, 1 Mole의 불화나트륨 용액을 와동에 적용시키고
CopaliteR를 도포한 실험군, 1 Mole의 불화나트륨 용액을 와동에 적용시키고
Cavity SealerR를 도포한 실험군들에서 치수에 나타난 반응을 병리조직학적으
로 관찰한 바 다음과 같은 결론을 얻었다.
1. 대조군에서는 조상아세포층의 변화가 실험후 3일에서 극심하게 나타났다가 점차 완화
되며 28일에서 증식등 회복반응을 나타내어 56일에서도 계속 관찰되었다.
2. Cavity SealerR군의 조상아세포층에서는 3일에서 경미한 출혈만 나타났
고 21일과 28일에서 증식이 나타났으며 56일에서 정상으로 관찰되었다.
3. DuraphatR군의 조상아세포층에서는 3일에서 경미한 출혈과 배열이상이
나타났고, 7일, 21일, 28일에서 배열이상이, 28일에서 증식이 나타났으며 56일에서 정상으로
관찰되었다.
4. CopaliteR눈의 7일에서는 기질에서의 출혈과 망상변성이 심하였고 조상
아세포층의 배열이상과 충혈이 나타났으며 전군에 걸쳐 배열이상이 관찰되었다.
#초록#
The purpose of this study was to observe the effect of dental varnish applied with
fluoride to dental pulp by comparing the groups of commercial fluoride product Duraphat
R, CopaliteR after 1 Mole sodium fluoiride application, Cavity
SealerR after 1 Mole sodium fluoride application with the control group not
applied the dental varnish.
After Cl V Cavity form was prepared on the buccal surface of the crowns with the
total 75 teeth by using 5 dogs, average weight of 13.2㎏, dental varnish and silver
analgram were placed. This study was performed by 3, 7, 21, 28, 56 days each. The
dogs were sacrificed to extract the teeth, cut at the apical one fourth, and prepared
histologic examination by fixing with 10% buffered formalin perfusion at sacrifice and
decalcification in 10% nitric acid. The specimens were embedded in paraffin, stained
with Hematoxylin and Eosin, and serially sectioned with 6μ width each.
Microscopic evaluation of serial sections at the various time periods among the
different groups revealed the following results:
1. In the control group, the marked change of the odontoblastic layer was showed on
the 3 days group, and it was decreased gradually, Healing response, such as hyperplasia,
was seen on the 28 days group and it was continued to the 56 days group.
2. In the experimental group with Cavity SealerR a slight hemorrhage
was seen in the odontoblastic layer on the 3 days group, and the healing response with
the hyperplasia of the odontoblast was showed on the 21, 28 days group. It was
completely healed on the 56 days group.
3. In the Duraphat R group, a slight hemorrhage showed on the 3 days group and the
disarrangement of the Odontoblastic layer was seen on the 7, 21, 28 days group.
Odontoblasts showed hyperplasia on the 28 days group, and healed completely on the 56
days group.
4. In the CopaliteR group, the 7 days group showed remarkable
hemorrhage in the odontoblastic layer and stroma, and also it showed reticular
degeneration with the disarrangement of the odontoblastic layer and congestion. Each
group showed disarrangement. Healing ability of this group was greater than that of the
control group, but less than that of the DuraphatR and Cavity
SealerR group.
