摘要： 目的·通过比较传统的菌斑控制方法（巴斯刷牙法）与其联合便携式冲牙器对牙龈炎和轻度慢性牙周炎成人患者光滑面菌斑控制和牙龈炎症控制效果的差别，明确冲牙器在口腔卫生维护中的作用。方法·共纳入78例牙龈炎和轻度慢性牙周炎成人患者，随机分为2组，即使用牙刷（对照组）和牙刷联合便携式冲牙器（实验组）。在基线、2周和6周后测量患者的菌斑指数（plaque index，PLI）、牙龈指数（gingiva index，GI）、出血指数（bleeding index，BI）和菌斑百分率。结果·对照组和实验组在连续口腔卫生维护2周后，PLI、BI、GI和菌斑百分率均较基线时降低（均P<0.05）。对照组和实验组在6周后，PLI、BI、GI和菌斑百分率均较基线时降低（均P<0.05）。连续口腔卫生维护2周及6周后，对照组和实验组的光滑面和邻面的BI较基线时均有所改善，且实验组光滑面和邻面的BI改善程度均显著优于对照组（均P<0.05）。结论·便携式冲牙器可以在牙周治疗和维护期间辅助患者实现更好的口腔卫生，帮助患者达到并维持牙周健康。

Abstract:
Objective · To compare the effect of traditional plaque control method (Bass method of tooth brushing) and the same method combined with portable dental irrigator on plaque control and gingival inflammation in adult gingivitis and mild chronic periodontitis patients, and explore the role of dental irrigator in oral health maintenance. Methods · Seventy-eight adult patients with gingivitis and mild chronic periodontitis were enrolled in this study. They were randomly divided into two groups, toothbrush (control group) and toothbrush combined with dental irrigator (experimental group). The plaque index (PLI), gingiva index (GI), bleeding index (BI) and plaque percentage were measured at baseline, after 2 weeks and 6 weeks respectively. Results · PLI, BI, GI and plaque percentage observed in the control group and experimental group were decreased after 2 weeks of continuous oral hygiene maintenance, compared with the baseline (all P<0.05). PLI, BI, GI and plaque percentage observed in the control group and experimental group were decreased after 6 weeks of continuous oral hygiene maintenance, compared with the baseline (all P<0.05). BIs of smooth surface and adjacent surface in the control group and experimental group after 2 weeks and 6 weeks were improved, compared with baseline, and the improvement of BI in the experimental group was significantly better than that in the control group (both P<0.05). Conclusion · Portable dental irrigator can assist patients to achieve better oral health during periodontal treatment and maintenance, and help them maintain periodontal health.
Key words: portable dental irrigator, plaque index (PLI), plaque percentage, bleeding index (BI), gingiva index (GI)
