Abstract

BACKGROUND

Preventing tooth loss is of utmost importance in maintaining optimal mastication, phonation, and aesthetics. Most commonly, pulpitis occurs as a result of caries, while trauma less frequently causes it. In both cases, it can lead to unbearable pain. To alleviate this pain and preserve the tooth without resorting to extraction, root canal treatment is indicated. To compare the radiographic quality of root canal filling sealing achieved with the Obtura II system and the cold lateral condensation technique.

METHODS

This randomized clinical trial was conducted at the School of Dentistry with a total of 260 participants. The study focused on single-rooted teeth that required endodontic treatment. Group A was assigned the cold lateral condensation, while Group B received obturation using the Obtura II system. A radiographic assessment was performed to evaluate the presence of voids and the extent of extension at the apex in both groups. The chi-square test was utilized to compare the occurrence of voids and the extent of extension between the two groups.

RESULTS

In the Cold Lateral Compaction cold lateral condensation group, 113 cases (86.92%) achieved optimum extension, while in the Obtura II group, 114 cases (87.69%) achieved the same. A statistically significant difference was observed between the groups in terms of extension (p=0.033). Although the difference in extension quality was not statistically significant, it is worth noting that the Obtura II group had a higher incidence of overextension. The cold lateral condensation group had 104 cases (80.00%) with no voids, whereas the Obtura II group had 121 cases (93.08%) without voids. A statistically significant difference was observed between the groups regarding the presence of voids (p=0.004).

CONCLUSIONS

Obtura II exhibits a denser sealing and fewer voids compared to the cold lateral condensation technique. However, Obtura II showed a slightly higher tendency to extend beyond the apex compared to the CLC technique.

摘要

背景

预防牙齿缺失对于维持最佳咀嚼、发音和美观至关重要。最常见的是，牙髓炎是由龋齿引起的，而创伤则较少引起。在这两种情况下，它都会导致难以忍受的疼痛。为了缓解这种疼痛并在不拔牙的情况下保留牙齿，需要进行根管治疗。比较 Obtura II 系统和冷侧压技术根管充填密封的放射学质量。

方法

这项随机临床试验在牙科学院进行，共有 260 名参与者。该研究集中在需要牙髓治疗的单根牙上。A 组采用冷侧压技术，B 组采用 Obtura II 系统进行根管充填。对两组进行放射学评估，以评估根尖有无空隙和根尖延伸程度。采用卡方检验比较两组之间有无空隙和根尖延伸程度。

结果

在冷侧压技术组中，113 例（86.92%）达到了最佳的延伸，而在 Obtura II 组中，114 例（87.69%）达到了同样的效果。两组之间的延伸程度存在统计学差异（p=0.033）。虽然延伸质量的差异没有统计学意义，但值得注意的是，Obtura II 组有更高的过度延伸发生率。冷侧压技术组有 104 例（80.00%）无空隙，而 Obtura II 组有 121 例（93.08%）无空隙。两组之间存在统计学差异（p=0.004）。
