Effective preventive treatment requires detailed knowledge of the etiological factors which contributed to the respective disease. For this reason, the various concepts of infectious disease that were discussed at one time or another are presented here. Special attention is given to the nonspecific and the specific plaque hypotheses. Current preventive strategies are based, however, on the concept of "opportunistic infections", which is scientifically well-documented and has been described in much detail. The following three preventive strategies are feasible: (1) eliminating plaque regularly and completely; (2) eliminating plaque to the level of the individual patient's characteristic limits for the disease in question; and (3) effecting changes in the microbiological composition of the plaque in order to eliminate the more highly pathogenic organisms and possibly to replace them with less pathogenic organisms.
有效的预防性治疗需要详细了解导致相应疾病的病因。因此，这里介绍曾经讨论过的各种传染病概念。特别关注非特异性菌斑假说和特异性菌斑假说。然而，目前的预防策略是基于“机会性感染”的概念，这一概念有充分的科学依据且已被详细描述。以下三种预防策略是可行的：（1）定期彻底清除菌斑；（2）将菌斑清除至个体患者针对所讨论疾病的特征性限度水平；（3）改变菌斑的微生物组成，以清除致病性更强的微生物，并可能用致病性较弱的微生物取而代之。
