Abstract

Introduction: This study investigates the influence of root length in mandibular molars with irreversible pulpitis on the success of supplemental intraligamentary injection following an inferior alveolar nerve (IAN) block. Various factors, including anatomical location, tooth type, and anesthetic solution, may affect supplemental anesthesia success.

Materials and methods: A total of 251 patients diagnosed with irreversible pulpitis in mandibular first or second molars underwent buccal infiltration anesthesia (4% articaine with 1:100,000 epinephrine) after IAN block injection (3% prilocaine and 0.03 IU/mL of felypressin). Fifty patients experiencing pain during access cavity preparation received supplemental intraligamentary injection (0.3 mL of 2% lidocaine with 1:80,000 epinephrine) at each mesial and distal line angle. The root length of treated teeth was recorded using an apex locator. Data analysis involved independent t-tests, Chi-square tests, and logistic regression.

Results: Successful supplemental intraligamentary injection was observed in 21 (42%) out of 50 patients. No significant correlation was found between the mean length of mesiobuccal (P=0.61), mesiolingual (P=0.34), or distal (P=0.60) canals of mandibular molars and the injection's success. Logistic regression analysis, however, revealed a significant impact of mesiolingual canal length on the success rate [OR 0.09 (0.01-0.79), P=0.030].

Conclusion: The root length of mandibular first and second molars does not significantly affect the success of supplemental intraligamentary injection.

评估下颌磨牙根长对补充韧带内注射治疗不可逆牙髓炎成功率的影响

导言：本研究探讨了患有不可逆牙髓炎的下颌磨牙的牙根长度对下牙槽神经（IAN）阻滞后韧带内补充注射成功率的影响。包括解剖位置、牙齿类型和麻醉溶液在内的各种因素都可能影响补充麻醉的成功率：共有 251 名被诊断为下颌第一或第二磨牙不可逆牙髓炎的患者在接受 IAN 阻滞注射（3% 普鲁卡因和 0.03 IU/mL 的非利司亭）后接受了颊部浸润麻醉（4% 阿替卡因和 1:100,000 肾上腺素）。50 名在准备入路腔时感到疼痛的患者在每个中线角和远线角接受了补充韧带内注射（0.3 mL 2% 利多卡因与 1:80,000 肾上腺素）。使用牙尖定位仪记录治疗牙齿的牙根长度。数据分析包括独立 t 检验、卡方检验和逻辑回归：结果：50 名患者中有 21 人（42%）成功进行了韧带内补充注射。下颌磨牙颊中管（P=0.61）、颊中管（P=0.34）或远端（P=0.60）的平均长度与注射成功率无明显相关性。然而，逻辑回归分析显示，中叶管长度对成功率有显著影响[OR 0.09 (0.01-0.79)，P=0.030]：下颌第一和第二磨牙的牙根长度对补充韧带内注射的成功率没有明显影响。

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.
