To evaluate the ability of the liquid-injectable OdneFill sealer to stay within the boundaries of prepared root canals of posterior teeth using a cadaveric model.
Eight maxillary bone blocks containing 3 to 5 posterior teeth were collected. Pre-operative radiographs were taken, and only maxillary premolars (n = 10) and molars (n = 16) were included. The canals were prepared with WaveOne Gold Primary and Large instruments, then randomly assigned to two groups (n = 33 canals). Group 1 used Warm Vertical Compaction with gutta-percha and AH Plus sealer, while Group 2 used only the OdneFill sealer to fill the canals. Post-operative radiographs were taken to assess sealer extrusion into the periapical tissues using a 4-point scale. Data analysis was conducted with a 5% significance level.
Out of 26 teeth examined (5 teeth were excluded), 47.6% (8 molars and 2 premolars) showed filling extrusion, with 77.8% of teeth in Group 1 (12 root canals) and 25.0% in Group 2 (3 root canals). A significant difference was found in the frequency of sealer extrusion between the two groups (P = 0.001), but no significant difference was observed between premolars and molars in terms of sealer extrusion frequency (P = 0.144).
The OdneFill filling protocol showed better control over extrusion compared to the Warm Vertical Compaction technique in posterior teeth of a cadaveric model.
This study highlights the potential of a new liquid-injectable root canal sealer designed to remain confined within the boundaries of the root canal anatomy.
使用尸体模型评估可注射液体 OdneFill 封闭剂保留在后牙预备根管范围内的能力。
收集8个包含3至5颗后牙的上颌骨块。拍摄术前X光片，仅纳入上颌前磨牙（n = 10）和磨牙（n = 16）。使用WaveOne Gold Primary和Large器械预备根管，然后随机分为两组（n = 33个根管）。第1组采用热垂直加压法使用牙胶尖和AH Plus封闭剂，而第2组仅使用OdneFill封闭剂填充根管。拍摄术后X光片，使用4分制评估封闭剂挤出至根尖周组织的情况。以5%的显著性水平进行数据分析。
在检查的26颗牙齿中（排除5颗牙齿），47.6%（8颗磨牙和2颗前磨牙）显示有充填物挤出，第1组77.8%的牙齿（12个根管）和第2组25.0%的牙齿（3个根管）出现这种情况。两组之间封闭剂挤出频率存在显著差异（P = 0.001），但在前磨牙和磨牙的封闭剂挤出频率方面未观察到显著差异（P = 0.144）。
在尸体模型的后牙中，与热垂直加压技术相比，OdneFill充填方案对挤出的控制更好。
本研究强调了一种新型可注射液体根管封闭剂的潜力，该封闭剂旨在限制在根管解剖结构范围内。
