The purposes of this study were to investigate the effect of direct application of chlorhexidine to periodontal pockets and the practicability of patient self-therapy using a technique of subgingival irrigation. Patients received no other oral hygiene instruction. After initial assessment of parameters, patients were given scaling and polishing and then instruction in the irrigation of designated pockets with chlorhexidine or a placebo using a disposable syringe and blunt needle. During the 28-day irrigation period with chlorhexidine there was highly significant reduction in periodontal inflammation which was maintained at levels significantly below the baseline values for a further 28-day period without irrigation. There was a deterioration in the periodontal state of those patients who had used the placebo, The irrigation technique itself caused no discernible injury in this group of routine periodontal patients. Also, staining in the chlorhexidine group was minimal. It is concluded that subgingival irrigation with chlorhexidine is effective in reducing periodontal inflammation and in controlling subgingival plaque. Intermittent treatment of this kind by the patient at home might reduce to more manageable levels the frequency of hygiene visits and the need for rigorous interdental oral hygiene.
本研究的目的是调查将洗必泰直接应用于牙周袋的效果以及使用龈下冲洗技术进行患者自我治疗的可行性。患者未接受其他口腔卫生指导。在对各项参数进行初步评估后，对患者进行洗牙和抛光，然后指导患者使用一次性注射器和钝头针用洗必泰或安慰剂冲洗指定的牙周袋。在使用洗必泰进行28天冲洗期间，牙周炎症显著减轻，在随后不进行冲洗的28天期间，炎症水平维持在显著低于基线值的水平。使用安慰剂的患者牙周状况恶化，冲洗技术本身在这组常规牙周患者中未造成明显损伤。此外，洗必泰组的染色极少。结论是，用洗必泰进行龈下冲洗可有效减轻牙周炎症并控制龈下菌斑。患者在家中进行这种间歇性治疗可能会将口腔卫生就诊的频率和严格的牙间口腔卫生需求降低到更易于管理的水平。
