Comparison of Clinical Efficacy of iRoot SP Single-Cone Obturation and Two Warm Gutta-Percha Vertical Compaction Techniques in Single-Visit Root Canal Treatment for Chronic Apical Periodontitis with Sinus Tract
摘要
Abstract
Objective To compare the clinical efficacy of iRoot SP single-cone obturation,iRoot SP paste with warm gutta-percha vertical compaction,and AH-Plus paste with warm gutta-percha vertical compaction in single-visit root canal treatment.Methods A retrospective study was conducted involving 155 patients with chronic apical periodontitis admitted to Handan Eye Hospital(Handan Third Hospital)from January 2022 to February 2025.Based on different treatment modalities,patients were divided into three groups:Group Ⅰ(50 cases,treated with iRoot SP single-cone obturation),Group Ⅱ(52 cases,treated with iRoot SP paste combined with warm gutta-percha vertical compaction),and GroupⅢ(53 cases,treated with AH-Plus paste combined with warm gutta-percha vertical compaction).The operation time,filling effect,pain level,sinus tract healing,masticatory function,periodontal indicators,clinical efficacy,and complications were compared among the three groups.Results The operation time in GroupⅠwas significantly shorter than that in GroupsⅡandⅢ(P<0.05);the operation time in GroupⅡwas significantly shorter than that in GroupⅢ(P<0.05).Visual analogue scale scores in all three groups decreased over time postoperatively(P<0.05).There was a significant interaction between postoperative evaluation time and group(P<0.05).At 3 days and 1 week postoperatively,VAS scores in GroupⅠwere significantly lower than those in GroupsⅡand Ⅲ(P<0.05),and scores in GroupⅡwere significantly lower than those in Group Ⅲ(P<0.05).Masticatory efficiency at 4 weeks postoperatively was significantly improved in all groups compared with preoperative levels(P<0.05);at 4 weeks,masticatory efficiency in Group Ⅰ[(76.03±8.12)%]was significantly higher than that in Groups Ⅱ and Ⅲ[(63.06±6.64)%and(60.45±6.23)%,respectively](P<0.05).Gingival index and plaque index at 4 weeks postoperatively were significantly lower than preoperative values in all groups(P<0.05);at 4 weeks,both indices in GroupⅠwere significantly lower than those in GroupsⅡandⅢ(P<0.05).Conclusion Compared with iRoot SP paste combined with warm gutta-percha vertical compaction and AH-Plus paste combined with warm gutta-percha vertical compaction,iRoot SP single-cone obturation demonstrated advantages in operation time,reduction of early postoperative pain,and promotion of masticatory function and periodontal recovery,while achieving comparable outcomes in filling effect,sinus tract healing,clinical efficacy,and overall safety.关键词
