Outline of Research at the Start

「モバイル遺伝子検査機」を用い、3菌種の歯周病菌(REDコンプレックス)を同時検出するチェアサイドPCR法を確立する。それを臨床応用し、歯面薬剤輸送システム(Dental Drug Delivery System (3DS))と組み合わせ、チェアサイドPCR法を活用して、歯周病菌除菌のための薬剤を選択あるいは開発し効果的な歯周病菌除菌システムの構築を試みる。

Outline of Final Research Achievements

Colonization by several oral pathogens and the onset of oral diseases, such as dental caries and periodontal diseases, are closely related. Therefore, the analysis of pathogens in oral specimens would be helpful for the risk assessment of oral diseases. We developed a rapid multiplex real-time polymerase chain reaction (PCR) method using a portable device and newly designed probe/primer sets to detect the oral pathogens Streptococcus mutans, Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia. The theoretical minimum detectable cell numbers of S. mutans, P. gingivalis, T. denticola, and T. forsythia were 1, 1, 4, and 3, respectively. The multiplex real-time PCR system simultaneously detected the colonization of S. mutans and P. gingivalis in human saliva.
These results suggest that the multiplex real-time PCR system may be useful for the risk assessment of oral diseases.

Academic Significance and Societal Importance of the Research Achievements

歯周病原因菌で「Red Complex」であるP. gingivalis、Treponema denticola、および Tannerella forsythiaは、これまでキットによるリスク判定や、選択培地による嫌気性培養が必要で培養および判定に時間を要していた。今回の研究では、唾液からリアルタイムPCRデバイスにより、チェアサイドでこれらの感染とリスク管理を行うための特異的なブローブ、プライマーの設計を行い評価した。唾液を検体とした臨床における迅速なリスク評価に適している。
