Ecological approach to periodontal pocket plaque control.

由于牙周袋内的细菌在牙周疾病中起着致病作用，因此对牙周袋内的微生物群进行定量和定性控制有利于预防牙周疾病的发生或发展。为了控制，对微生物群的生态理解是必不可少的。厌氧和解蛋白条件是牙周袋的生态特征，绝大多数菌群由厌氧、解糖菌组成，其中部分菌群应划分为新属或新种。根据这些特点，考虑了共聚集因子、质粒、抗菌酶、药物和制剂，以及牙周袋本身的去除，对牙周袋内微生物群进行了定量和定性控制。

Quantitative and qualitative controls of microflora in periodontal pockets are of benefit to prevent the onset or progress of periodontal disease, since bacteria in periodontal pockets play pathogenic roles in periodontal diseases. To control, ecological understanding of the microflora is essential.Anaerobic and proteolyic conditions were the ecological characteristics of periodontal pockets, and overwhelming majority of the flora was constituted by anaerobic, asaccharolytic bacteria, some of which should be classified to new genera or species.According to these characteristics, co-aggregation factors, plasmids, and antibacterial enzymes, drugs and agents, as well as the removal of pockets itself, were considered for the quantitative and qualitative controls of microflora in periodontal pockets.
