타액내의 정상균총 및 발치후 발치와내의 세균학적 연구

Abstract

[한글]

구강내는 많은 미생물이 존재한다. 구강은 혀, 협점막, 치아, 치은열구등의 해부학적 구조가 미생물이 집락하기 좋은 부위이며 이런 해부학적 특성 이외에도 생리적 기능적 특성으로 성장하기에 좋은 온도 습도등을 제 한다.

여러 선학들의 연구에 의하면 그것들은 치성감염시 병원균으로 작용가능하다. 그렇지만 단순발치후 발치와내에서 발견되는 세균들에 관한 연구가 적어 발치후 야기될 수 있는 감염증의 예방 및 치료에 큰 도움을 얻고자 저자는 치주질환 및 치근단염증으로 인해 발치를 필요로 하는 환자 50명에 대해 발치전 타액내와 발치직후 발치와내의 세균을 호기성과 혐기성으로 분리동정하여 다음과 같은 결론을 얻었다.

1. 전체 분리된 균주는 563주였다. 이것은 1인평균 11.3주 분리된 것이다.

2. 전체 호기성, 혐기성 분리균주는 각각 355주, 208주였다. 이것은 1인평균 7.1주, 4.2주 분리된 것이다.

3. 타액내와 발치와내의 분리균주는 276주, 287주였다. 각각의 호기성, 혐기성 균주는 184주와 92주 및 171주와 116주였다.

4. 타액과 발치와의 비교시 가장 빈도수가 높은 것은 다음의 것들이다.;

Streptococcus viridans 45주 (24%)

Haemophilus parainfluenzae 33주 (18%)

There are many microorganisms in oral cavity. Numerous factors may influence on the com-position of oral flora. By the studies of previous investigators, they possibly act as a pathogens in odontogenic infections. But there was no description of the organisms which are found in the simple extraction socket immediately after the tooth has been removed.

If the valid theories are to be advanced concerning the relationship to postoperative inflammation, knowledge of the early bacterial study is essential.

Fifty-patients were chosen for this study who visited Catholic Medical College Hospital, department of dentistry, during the period of March to May 1984 under the diagnosis of pulpitis and periodontitis. They all had been swabbed from saliva. And

with local anesthesia, all had been pulled out single tooth. From the extraction socket, swabbing had been done like sampling of saliva. Those samplings were transported to the laboratory as soon as possible and cultured aerobically : anaerobically.

The obtained results were as follows;

1. Total cultured strains were 565 strains.

The average number of bacteria identified was 11.2 strains per person.

2. Total aerobic strains were identified 355, anaerobes,208 with the average of 7.1 and 4.1 strains per person respectively.

3. Total cultured strains of saliva were 276 strains.

Total cultured strains of Extraction socket were 287 strains. Their aerobes and anaerobes were 184,92 strains, and 171,116 strains respectively.

4. In comparison between bacterial species in saliva and extraction socket, moat frequently identified groups were as follows;

In saliva

aerobic groups were

streptococcus viridans 45 strains (24%)

Haemophilus patwainfluenzae 33 strains (18%)

Branhamella catarrhalis 29 strains (16%)

Anaerobic groups were

Bacteroides oralis 22 strains (24%)

Bactoroides melanioosicus 13 strains (14%)

anaerobic streptococci 10 strains (11%)

In extraction socket

aerobic groups were

streptococcus viridans 42 strains (25%)

Branhamella catarrhalis 31 strains (18%)

Haemophilos p arainfluenzae 26 strains (15%)

anaerobic froup were

Bacteroides oralis 24 strains (21%)

Bactreoides melaninogenicus 23 strains (20%)

Fusobactreium nucleatum 11 strains (9%)
