상아질 산부식 처리 및 복합레진 충전이 성견 치수에 미치는 영향에 관한 실험적 연구

Abstract

[한글]

저자는 복합레진 수복과 상아질 산처리가 치수에 미치는 영향을 규명하기 위하여 체중 10-14kg의 건강한 성견 6마리의 상하악 전치 및 소구치 120개 치아에 와동을 형성하고 상아질 산처리 유무와 이장재 도포 유무에 의하여 군을 분류한 다음 복합레진을 충전하고

치수조직 반응을 관찰하여 다음과 같은 결론을 얻었다.

1. 대조군, 실험군 공히 3일 경과시 산처리와 이장재 도포에 관계없이 경미한 치수반응을 보였다.

2. 2주, 4주 경과시 상아질 산처리 군과 처리하지 않은 군에서 공히 치수의 염증반응을 보이지 않았다.

3. 이장재를 도포한 군과 도포하지 않은 군간의 치수반응의 차이는 없었다.

4. 2주, 4주 경과시 Silux^^ 충전군과 대조군 사이의 치수반응의 차이는 없었다.

THE HISTOPATHOLOGIC STUDY ON THE EFFECTS OF DENTIN-ACID-ETCHING AND COMPOSITE RESIN

RESTORATION ON THE PULP OF THE ADULT DOGS

Tai Hyoung, Jung

Department of Dental Science, Graduate School, Yonsei University

(Directed by Prof Jong Gap Lee, D.D.S., M.S.D., Ph.D.)

For the purpose of the assessment of the effects of dentin-acid-etching and

composite resin restoration on the pulp, the cavities were formed on the teeth of

the adult dogs. The specimens were classified by the presence of base on the

cavities, and filled the composite resin in those cavity. And the response of pulp

tissue was observed.

The following results were obtained,

1. No specific differences but, mild response of pulp tissue was seen in

experimental group and control group after 3 days, whether acid treated and the

base applied or not.

2. No inflammatory reaction of pulp tissue was observed in both acid-treated

dentin and non-acid-treated group, after 2 weeks and 4 weeks.

3. No specific differences in the degree of pulp tissue response observed between

the base applied group and non-base applied group.

4. No specific differences in the degree of pulp tissue response was observed,

between silux^^ -applied (filling) group and zinc-oxide-eugenol cement-filling

group, after 2 weeks and 4 weeks.
