Objective To investigate the improvement of clinical symptoms in patients with chronic periodontitis(CP)with Er∶YAG assisted periodontal basal therapy.Methods A total of 106 CP patients admitted to Xinjiang Uiger Municipal People's Hospital from January 2019 to April 2022 were selected and divided into conventional group(n=53)and study group(n=53)by random number table method.The conventional group received periodontal basal therapy,and the study group received Er∶YAG treatment on the basis of the conventional group.The efficacy,occurrence of adverse reactions,before treatment and three months after treatment the clinical indicators[probing depth(PD),gingival index(GI),clinical attachment loss(CAL)],and inflammatory factors in gingival creval fluid[Tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)]of the two groups were compared.Results The total effective rate of the study group was 92.45％higher than that of the conventional group 75.47％(P＜0.05).At three months after treatment,PD,GI and CAL were decreased in the study group and the conventional group,and the study group was lower than the conventional group(P＜0.05).After three months of treatment,the levels of TNF-α and IL-6 in gingival crevicular fluid in two groups were decreased,and the levels in the study group were lower than those in the conventional group(P＜0.05).The incidence of adverse reactions was 13.21％in the study group and 7.55％in the conventional group,with no significant difference between the groups(P＞0.05).Conclusion Er∶YAG assisted periodontal basal therapy can effectively relieve the clinical symptoms of CP patients,improve the periodontal condition,reduce periodontal inflammation,and has good safety.
