Abstract: Objective: To evaluate the significance of the AirFloss for plaque control to patients of periodontal diseases. Methods:One hundred and twenty patients of periodontal diseases were randomly assigned to four groups:the manual tooth brushing;the dental floss plus manual tooth brushing;the AirFloss plus manual tooth brushing; the AirFloss. After periodontal initial therapy, oral hygiene tests were performed in four groups of patients at the first month(M1) and third month(M3), and the gingival index GI and Quigley-Hein plaque index were compared between the groups. Results: After one month, the PLI and GI of the AirFloss plus manual tooth brushing were decreased by 47% and 44.9%.And after three month, PLI and GI were decreased by 62.9%和58.4%, and the difference was statistically significant at the two time points(P<0.05).And after one month,the PLI and GI index of the dental floss plus manual tooth brushing respectively decreased by 9% and 10% compared to the baseline examination (P>0.05). After three months ,the PLI and GI were decreased by 15.6% and 16% (P>0.05). Afer one month and three months,the PLI and GI index of simple manual tooth brush group and the airfloss group was no significant baseline examination the difference. Conclusion: The airfloss can significantly reduce plaque in patients with periodontal disease adhesion, improve gingival inflammation, is an effective auxiliary oral cleaning device with periodontal disease.
