A study was made of the effect of wearing partial dentures upon plaque accumulation in a group of 24 partial denture wearers, when oral hygiene procedures were withdrawn. The modifying effect of a 1% chlorhexidine gluconate gel on this plaque accumulation was measured. Plaque accumulation was measured at the end of four different denture-wearing regimens each 3 days in length. The wearing of a partial denture either day only or day and night, significantly increased plaque accumulation over not wearing a denture. There was no significant difference between plaque accumulation with day wear and day and night wear. The increase in plaque accumulation with day and night wear resulted from an equal and significant increase in both buccal and lingual plaque accumulation. Chlorhexidine gluconate in the form of a gel significantly reduced plaque accumulation during daytime wear. These results tend to confirm that plaque control is a major factor in determining the long-term effects of partial dentures upon the periodontal structures and emphasize the importance of oral hygiene in partial denture wearers.
对24名佩戴局部义齿者在停止口腔卫生措施时，佩戴局部义齿对菌斑积聚的影响进行了研究。测量了1%葡萄糖酸氯己定凝胶对这种菌斑积聚的改良作用。在四种不同的义齿佩戴方案结束时（每种方案为期3天）测量菌斑积聚情况。仅在白天佩戴局部义齿或白天和晚上都佩戴，与不佩戴义齿相比，显著增加了菌斑积聚。白天佩戴和白天及晚上都佩戴时的菌斑积聚没有显著差异。白天和晚上都佩戴导致菌斑积聚增加是由于颊侧和舌侧菌斑积聚均有同等程度的显著增加。凝胶形式的葡萄糖酸氯己定在白天佩戴期间显著减少了菌斑积聚。这些结果倾向于证实菌斑控制是决定局部义齿对牙周组织长期影响的一个主要因素，并强调了局部义齿佩戴者口腔卫生的重要性。
