Abstract

This study utilized an analysis method for detecting six microorganisms, such as Actinobacillus actinomycetemcomitans, Campylobacter rectus, Porphyromonas gingivalis, Tannerella forsythus, Treponema denticola, and Prevotella intermedia, triggering periodontal disease, using multiplex real-time polymerase chain reaction (PCR). The analysis including internal control was made by dividing the six species into two groups using four fluorescence dyes, and it was verified that there was no interference or cross-reaction between the target species and different kinds of oral microbial species. Qualitative and quantitative analyses were conducted on each microorganism in various samples, such as saliva and the plaque, using the multiplex real-time PCR and comparative analysis between periodontitis patients and healthy people, revealing obvious differences between them.

본 연구는 multiplex real-time PCR을 이용하여 Actinobacillus actinomycetemcomitans, Campylobacter rectus, Porphyromonas gingivalis, Tannerella forsythus, Treponema denticola, Prevotella intermedia 등과 같은 6종의 주요 치주 질환 원인 미생물들을 동시에 검출할 수 있는 분석 방법에 관한 것이다. 4개의 형광 염료를 사용하여 internal control과 함께 3개의 균종씩 나누어 분석하였으며, 분석 대상 균종 간 그리고 다른 종류의 구강 미생물 균종과의 간섭과 교차 반응이 없음을 확인하였다. 본 연구의 multiplex real-time PCR은 타액과 플라그 등의 다양한 샘플에 포함되어 있는 각 미생물들을 정성, 정량적으로 분석할 수 있었으며, 치주염 환자와 건강한 사람들에 대한 비교 분석 결과 분명한 차이를 발견 할 수 있었다.
