Abstract:
Objective:To evaluate the clinical efficacy of subgingival irrigation with chlorhexidine as an adjunct to ultrasonic subgingival scaling for the treatment of moderate to severe chronic periodontitis in elderly patients.Methods:Twenty-two elderly patients diagnosed with moderate to severe chronic periodontitis were randomly assigned to test and control groups based on mouth side.In the test group, 0.02% chlorhexidine was used in place of distilled water for irrigation during ultrasonic scaling, while the control group received routine ultrasonic subgingival scaling.The plaque index(PLI), probing depth(PD), clinical attachment level(CAL), gingival bleeding index(BI), and percentage of bleeding on probing(BOP)were recorded at baseline, 6 weeks post-treatment, and 3 months post-treatment.Results:At 6 weeks and 3 months post-treatment, both the test and control sides exhibited a significant reduction in PD from baseline(both P<0.05).However, the magnitude of change was comparable between the two sides, with no statistically significant difference observed( P=0.591, 0.106).Both sides also demonstrated statistically significant differences in CAL at 6 weeks and 3 months compared to baseline(both P<0.05).Although the change in the test side was slightly greater than that in the control side, this difference was not statistically significant( P=0.758, 0.909).Regarding BI, both sides showed a significant difference from baseline at both 6 weeks and 3 months(both P<0.05), with statistically significant differences between the test and control groups( P=0.003, 0.015), indicating a significantly better improvement in gingival bleeding on the test side.Similarly, both sides demonstrated improvement in BOP at 6 weeks and 3 months, with the test side showing a significantly better improvement than the control side( P=0.005, 0.019).The PLI also showed statistically significant differences compared to baseline at 6 weeks and 3 months(both P<0.05); however, there was no statistically significant difference between the two sides(both P>0.05). Conclusions:The use of ultrasonic scalers in conjunction with chlorhexidine for subgingival scaling and root planning can significantly enhance pocket depth reduction and decrease gingival bleeding in elderly patients suffering from chronic periodontitis.When compared to traditional treatment methods, the therapeutic outcomes of ultrasonic scalers combined with chlorhexidine are superior and more favorable for the elderly population.
