Abstract

Objective: The purpose of this study was to evaluate the effectiveness of using cold plasma after curettage after 3 weeks of follow-up in the group of patients with 3 to 5mm periodontal pockets. Methodology: The present study included 64 patients with 906 teeth which had 3-5 mm periodontal pockets divided into 2 groups: control and intervention group.Both groups had periodontal pocket curettage surgery according to the same method, evaluation after 3 days and 3 weeks based on indicators (DI, PI, CAL, PD) and levels of healing . Only the intervention group used cold plasma after periodontal pocket curettage surgery. Results: mean of plaque index (PI) in the 3rd week after treatment in the test and the control group decreased 1.8 and 1.5 times respectively. Another decrease was observed at mean of gingival index (GI), which decreased 1.3 times in test group and 1.1 times in control group.Mean of pocket depth (PD) also improved in both groups. Furthermore, the intervention group showed mean of PD decreasing more significantly (1.8 mm; 3.1702 ± 0.3732, 1.3827 ± 0.3615 before treatment and 3 weeks later, respectively) compared to the control one (1,2mm; 3.1821 ± 0.3852, 1.9102 ± 0.4055 before treatment and 3 weeks later). The percentage of patients achieving good treatment outcomes accounted for 96,9% in the test group, but only 37,5% in the control one in three days follow-up. After 3 weeks, the proportion of patients gaining good treatment outcomes accounted for 93,8% in the intervention group and just 78,1% in the control one. Conclusion: Using cold plasma after curettage of patients with 3 to 5mm periodontal pockets has high efficiency.
