Effectiveness of Microscopic Root Canal Treatment Based on Periodontal Microbial Ecology Assessment in the Treatment of Radicular Groove-Associated Pulpal-Periodontal Lesions
Objective:To evaluate the effectiveness of microscopic root canal treatment based on perio-dontal microbial ecology assessment in the treatment of radicular groove-associated pulpal-periodontal lesions.Methods:A total of 118 patients diagnosed with radicular groove-associated pulpal-periodontal lesions from October 2020 to October 2023 were randomly divided into two groups:the control group(n=59)treated with periodontal tissue regeneration surgery,and the observation group(n=59)treated with microscopic root canal treatment combined with periodontal tissue regeneration surgery.The distribution of periodontal microbiota,gingival index(GI),sulcus bleeding index(SBI),plaque index(PLI),tooth mobility(TM),as well as treatment efficacy and safety were compared between the two groups before and after surgery.Results:At 1 week postoperatively,the observation group showed lower detection rates of Streptococcus mutans,Porphy-romonas gingivalis,and Fusobacterium nucleatum in periodontal pockets compared to the control group(P<0.05).The observation group also exhibited lower GI,SBI,PLI,and TM compared to the control group at 1 week postoperatively(P<0.05).The clinical efficacy in the observation group was superior to that in the con-trol group,and both groups did not experience significant complications.Conclusion:Microscopic root canal treatment for radicular groove-associated pulpal-periodontal lesions demonstrates significant effectiveness,ef-fectively improves periodontal microbiota and microbial ecology,and reduces tooth mobility.
