Abstract：Objective To investigate the effect of systematic oral care on plaque control and oral hygiene behaviours of patients with periodontal disease. Methods 〓Totally 80 patients with periodontal disease were assigned to the observation group and the control group, with 40 cases in each group. The control group received routine care during the treatment, and the observation group was given systematic interventions of oral care. The effect on plaque control and oral hygiene behaviours of patients were evaluated and compared between two groups. Results 〓The outcomes of gingival index, gingival bleeding index, depth of periodontal probe penetration and plaque index were improved after the intervention, and the effect on plaque control in the observation group was superior than that in the control group(P<0.05). The proportions of patients who brushed teeth more than 3 times per day, brushed teeth more than 3 minutes per time, adopted vertical brushing or fibrillation brushing, used dental floss appropriately in the observation group were higher than those in the control group, respectively(P<0.05). Conclusion 〓The systematic oral care is potentially effective to control the dental plaque and improve the oral hygiene behaviours of patients with periodontal disease.
