Science, in the search for truth, is dynamic and constantly changing. Periodically, an innovative idea such as subgingival irrigation emerges, which needs to be tested and retested. If the results are statistically and clinically meaningful, it then can be incorporated into treatment and maintenance regimes. This article addresses advantages and limitations of subgingival irrigation as it pertains to the treatment of patients with periodontitis. The subject is controversial, because while the role of supragingival irrigation is being recognized in the treatment of gingivitis, the status of subgingival irrigation in periodontitis therapy still needs further clarification. Four major themes are addressed within this text: (1) to explore the biologic rationale for subgingival irrigation, since treatment decisions must be based upon scientific data and not upon empiricisms; (2) to place in perspective the ability of subgingival irrigation (which also will be referred to as irrigation or lavage) to enhance periodontal health by assessing data from controlled studies; (3) to encourage use of subgingival irrigation as an adjunct to conventional therapy, in certain situations; and (4) to discourage bad execution of a good idea, because if limitations of lavage are not recognized, therapists may engage in ineffective treatment.
科学在追求真理的过程中是动态的，且不断变化。时不时会出现诸如龈下冲洗这样的创新理念，这需要反复进行测试。如果结果在统计学和临床上有意义，那么它就可以被纳入治疗和维护方案中。本文探讨了龈下冲洗在治疗牙周炎患者方面的优点和局限性。这个话题存在争议，因为虽然龈上冲洗在牙龈炎治疗中的作用已得到认可，但龈下冲洗在牙周炎治疗中的地位仍需进一步明确。本文围绕四个主要主题展开：（1）探究龈下冲洗的生物学原理，因为治疗决策必须基于科学数据而非经验主义；（2）通过评估对照研究的数据，正确看待龈下冲洗（也将被称为冲洗或灌洗）改善牙周健康的能力；（3）鼓励在某些情况下，将龈下冲洗作为传统治疗的辅助手段；（4）避免对好想法的不当实施，因为如果不认识到灌洗的局限性，治疗师可能会进行无效治疗。
