To compare the clinical efficacy between the methods of Cold Lateral Compaction (CLC) and Warm Vertical Condensation (WVC) in treating C-shaped root canals, focusing on periodontal health, fracture resistance, postoperative pain, and the incidence of secondary caries.
This retrospective cohort study involved 229 patients treated with either CLC (n=106) or WVC (n=123) from January 2022 to December 2023. Baseline characteristics were comparable between the two groups. Clinical data on clinical efficacy, periodontal indices, fracture resistance, pain scores, and secondary caries incidence were collected and analyzed.
The WVC technique demonstrated superior clinical outcomes, with an effectiveness rate of 95.93% compared to 87.74% for CLC (P=0.022). Patients treated with WVC showed significantly greater improvements in periodontal indices, including reduced plaque and gingival indices, probing depth, and tooth mobility one month post-treatment (all P<0.05). Additionally, the WVC group exhibited enhanced fracture resistance, with shorter dye penetration lengths and higher compressive load capacity (P=0.004 and P=0.006, respectively). Postoperative pain was reduced in the WVC group, as indicated by lower Visual Analog Scale (VAS) scores (P=0.027). Furthermore, the incidence of secondary caries at 24 months was significantly lower in the WVC group (11.38% vs 23.58% for CLC, P=0.014). The WVC group also showed marked reductions in inflammatory markers postoperatively, including interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), interleukin-8 (IL-8), and C-reactive protein (CRP) (P<0.05).
The WVC technique is more effective than CLC for C-shaped root canals. It not only provides superior sealing capabilities but also improves periodontal health, increases fracture resistance, reduces postoperative pain, and lowers the incidence of secondary caries.
比较冷侧向加压法（CLC）和热垂直加压法（WVC）治疗C形根管的临床疗效，重点关注牙周健康、抗折性、术后疼痛和继发龋发生率。
本回顾性队列研究纳入了2022年1月至2023年12月期间接受CLC（n = 106）或WVC（n = 123）治疗的229例患者。两组的基线特征具有可比性。收集并分析了关于临床疗效、牙周指数、抗折性、疼痛评分和继发龋发生率的临床数据。
WVC技术显示出更好的临床效果，有效率为95.93%，而CLC为87.74%（P = 0.022）。接受WVC治疗的患者在治疗后1个月牙周指数有显著改善，包括菌斑和牙龈指数降低、探诊深度减小以及牙齿松动度降低（均P < 0.05）。此外，WVC组的抗折性增强，染料渗透长度更短，抗压负荷能力更高（分别为P = 0.004和P = 0.006）。WVC组术后疼痛减轻，视觉模拟量表（VAS）评分更低（P = 0.027）。此外，WVC组24个月时继发龋的发生率显著更低（11.38%对比CLC的23.58%，P = 0.014）。WVC组术后炎症标志物也显著降低，包括白细胞介素-6（IL-6）、肿瘤坏死因子-α（TNF-α）、白细胞介素-8（IL-8）和C反应蛋白（CRP）（P < 0.05）。
对于C形根管，WVC技术比CLC更有效。它不仅提供了更好的封闭能力，还改善了牙周健康，提高了抗折性，减轻了术后疼痛，并降低了继发龋的发生率。
