Abstract

Introduction: The current study aimed to compare the quality of root canal obturation performed with cold lateral condensation with other obturation techniques.

Materials and methods: Diverse Search was conducted using six electronic/academic databases following PICOS (i.e. population, intervention, control, outcomes, and study design) strategy: (P) Extracted mature permanent teeth; (I) Obturation techniques except for cold lateral condensation; (C) Cold lateral condensation tyechnique; (O) Quality of root canal obturation; and (S) In vitro studies assessing parameters using micro-computed tomography. The statistical method used for the meta-analyses was the "inverse variance DerSimonian-Laird test". The heterogeneity data was calculated using the T2, Cochran Q test, and I2 statistics.

Results: Fifteen studies were included for the final analysis; one had a low risk of bias, eight a moderate risk, and six a high risk of bias. Ten studies were selected for meta-analyses; three studies comparing cold lateral condensation with carrier-based gutta-percha techniques [P=0.96; mean difference (MD)=-0.02; confidence interval (CI): (-0.77, 0.73); I2=21%]; three comparing cold lateral condensation with single-cone techniques [P=0.75; MD=-0.39; CI: (-2.77, 1.99); I2=92%]; two comparing cold lateral condensation and thermo-plasticized injectable techniques [P=0.37; MD=5.91; CI: (-7.13,18.94); I2=99%]; and five comparing cold lateral condensation with warm vertical condensation techniques [P<0.0001; MD=5.29; CI=(2.84, 7.74); I2=92%]. The overall effect reported significant results [P=0.0003; MD=2.69; CI=(1.23, 4.16); I2=96%]; favoring fewer voids and gaps for the other used obturation techniques.

Conclusions: Cold lateral condensation and single-cone techniques presented no statistical differences. Nonetheless, Warm vertical condensation technique had better results compared to cold lateral condensation.

封闭技术对根管充填质量的影响：体外研究的系统回顾与元分析》。

导言本研究旨在比较冷侧凝与其他封堵技术的根管封堵质量：按照 PICOS（即人群、干预、对照、结果和研究设计）策略，使用六个电子/学术数据库进行了多元化检索：（P）拔除的成熟恒牙；（I）除冷侧凝外的封闭技术；（C）冷侧凝技术；（O）根管封闭的质量；（S）使用微型计算机断层扫描评估参数的体外研究。荟萃分析使用的统计方法是 "逆方差 DerSimonian-Laird 检验"。异质性数据使用 T2、Cochran Q 检验和 I2 统计量进行计算：最终分析纳入了 15 项研究，其中 1 项研究存在低偏倚风险，8 项研究存在中度偏倚风险，6 项研究存在高度偏倚风险。10项研究被选中进行荟萃分析；其中3项研究比较了冷侧凝技术和载体型古塔胶技术[P=0.96；平均差（MD）=-0.02；置信区间（CI）：（-0.77，0.73）；I2=21%]；3项研究比较了冷侧凝技术和单凝技术[P=0.75；MD=-0.39；CI：（-2.77，1.99）；I2=92%]。99）；I2=92%]；冷侧凝与热塑化注射技术比较2例[P=0.37；MD=5.91；CI：（-7.13，18.94）；I2=99%]；冷侧凝与温垂直凝结技术比较5例[PP=0.0003；MD=2.69；CI=（1.23，4.16）；I2=96%]；其他使用的封堵技术的空洞和间隙更少：结论：冷侧向冷凝技术和单锥体技术没有统计学差异。尽管如此，暖垂直冷凝技术比冷侧冷凝技术的效果更好。

期刊介绍： The Iranian Endodontic Journal (IEJ) is an international peer-reviewed biomedical publication, the aim of which is to provide a scientific medium of communication for researchers throughout the globe. IEJ aims to publish the highest quality articles, both clinical and scientific, on all aspects of Endodontics. The journal is an official Journal of the Iranian Center for Endodontic Research (ICER) and the Iranian Association of Endodontists (IAE). The Journal welcomes articles related to the scientific or applied aspects of endodontics e.g. original researches, systematic reviews, meta-analyses, review articles, clinical trials, case series/reports, hypotheses, letters to the editor, etc. From the beginning (i.e. since 2006), the IEJ was the first open access endodontic journal in the world, which gave readers free and instant access to published articles and enabling them faster discovery of the latest endodontic research.
