To evaluate the effect of irrigation with 0.06% chlorhexidine (PerioGard) (CHX) using a powered oral irrigator (Water Pik) with a special subgingival irrigating tip (Pik Pocket Subgingival Tip) compared to rinsing with 0.12% chlorhexidine gluconate once daily.
Following a prophylaxis, patients were randomly assigned to an irrigation or a rinse group. The following clinical parameters were measured at baseline and at the 3-month end of the study: Modified Gingival Index (MGI), Plaque Index (PI), Bleeding Index (BI), and Calculus Index (CI). Also, a Stain Index (SI) was measured at 3 months.
Patients irrigating with diluted CHX showed a statistically significant reduction (P < 0.05) from their baseline in the MGI, PI, BI, and CI scores at 3 months. In the rinse group both MGI and BI showed statistically significant reduction from their baseline (P < 0.05) at 3 months. The rinse group showed a nonsignificant (P > 0.05) increase from baseline in CI and a nonsignificant decrease in PI. Intergroup comparisons showed that CHX irrigation produced statistically significantly greater reductions than CHX rinsing in the PI, MGI, and SI. The irrigation group also showed a greater reduction in BI and CI than the rinsing group but these differences were not statistically significant (P = 0.12). The results of this study suggest that use of diluted 0.06% CHX when used in a powered irrigator may be a valuable adjunct to oral health in patients with implants.
评估使用配备特殊龈下冲洗头（牙线洁治龈下冲洗头）的电动口腔冲洗器（洁碧冲牙器）冲洗0.06%氯己定（派丽奥）（CHX）与每日一次用0.12%葡萄糖酸氯己定漱口相比的效果。
在进行预防性治疗后，将患者随机分为冲洗组或漱口组。在基线和研究的3个月末测量以下临床参数：改良牙龈指数（MGI）、菌斑指数（PI）、出血指数（BI）和牙石指数（CI）。此外，在3个月时测量染色指数（SI）。
用稀释的CHX冲洗的患者在3个月时，其MGI、PI、BI和CI评分与基线相比有统计学显著降低（P < 0.05）。在漱口组中，MGI和BI在3个月时与基线相比均有统计学显著降低（P < 0.05）。漱口组的CI与基线相比有不显著的增加（P > 0.05），PI有不显著降低。组间比较显示，CHX冲洗在PI、MGI和SI方面产生的统计学显著降低幅度大于CHX漱口。冲洗组在BI和CI方面的降低幅度也大于漱口组，但这些差异无统计学意义（P = 0.12）。本研究结果表明，在电动冲洗器中使用稀释的0.06% CHX可能是植入物患者口腔健康的一种有价值的辅助手段。
