The aim of this study was to assess the efficacy of inferior alveolar nerve (IAN) block combined with buccal infiltration for mandibular molars with irreversible pulpitis.
Eighty-four patients were randomly assigned to 3 groups of 28 patients each. Lidocaine 2% with 1:80,000 epinephrine was used for all injections. Group I patients received an IAN block with 1.8 mL of anesthetic. Group II patients received an IAN block using 3.6 mL. Group III patients received 1.8 mL as an IAN block and 1.8 mL as a buccal infiltration. A visual analogue scale was used to rate pain before anesthesia and discomfort experienced before and during access cavity preparation. Data were analyzed by chi-square, ANOVA, Kruskal-Wallis, and Mann-Whitney tests.
The success rates for groups I to III were 14.8%, 39.3%, and 65.4%, respectively. Group III had significantly better anesthesia compared with group I (P < .05).
Combining an IAN block and a buccal infiltration injection provided more effective anesthesia in mandibular molars with irreversible pulpitis. However, some cases may still require further anesthesia to prevent pain during endodontic treatment.
本研究旨在评估下牙槽神经（IAN）阻滞联合颊侧浸润麻醉用于下颌磨牙不可逆性牙髓炎的疗效。
84例患者被随机分为3组，每组28例。所有注射均使用含1:80,000肾上腺素的2%利多卡因。I组患者接受1.8 mL麻醉剂的IAN阻滞。II组患者接受使用3.6 mL的IAN阻滞。III组患者接受1.8 mL的IAN阻滞和1.8 mL的颊侧浸润麻醉。采用视觉模拟量表对麻醉前的疼痛以及开髓预备前和过程中经历的不适进行评分。数据通过卡方检验、方差分析、Kruskal-Wallis检验和Mann-Whitney检验进行分析。
I组至III组的成功率分别为14.8%、39.3%和65.4%。III组的麻醉效果明显优于I组（P < 0.05）。
IAN阻滞联合颊侧浸润麻醉在下颌磨牙不可逆性牙髓炎中提供了更有效的麻醉。然而，一些病例可能仍需要进一步麻醉以防止牙髓治疗期间的疼痛。
