Mandibular infiltration has been routinely avoided in treating mandibular molars because of its questionable adequacy. The purpose of our investigation was to determine the effectiveness of mandibular infiltration compared with mandibular block in treating primary molars in children, and to relate the effectiveness to age and type of treatment performed. The study population consisted of 89 cooperative children, 3 to 9 years old, requiring the same type of treatment on contralateral mandibular molars. The half-mouth study design was used. Dental procedures included class I and II amalgam restorations, stainless steel crowns, formocresol pulpotomies, and extractions. Evaluations of pain and behavior for each anesthesia technique and type of treatment were made using sounds, motor, and ocular changes indicating pain and the Frankl Behavior Rating Scale. Evaluations were made upon probing, rubber dam placement, and during tooth preparation and extraction. No statistically significant differences was found between the two anesthetic techniques for either behavior or pain when performing amalgam or stainless steel crown restorations (P = 0.05). Mandibular infiltration was less effective than mandibular block for pulpotomy and extraction (P = 0.05). No significant relationship to age as determined by primary or mixed dentition, for effectiveness was noticed.
由于下颌浸润麻醉的效果存疑，治疗下颌磨牙时通常不采用该方法。我们研究的目的是确定在下颌乳磨牙治疗中，下颌浸润麻醉与下颌阻滞麻醉相比的有效性，并将有效性与年龄及所进行的治疗类型相关联。研究对象包括89名3至9岁的合作儿童，他们双侧下颌磨牙需要进行相同类型的治疗。采用半口研究设计。牙科治疗程序包括I类和II类银汞合金修复、不锈钢冠修复、甲醛甲酚牙髓切断术和拔牙。使用表明疼痛的声音、动作和眼部变化以及弗兰克行为评定量表，对每种麻醉技术和治疗类型的疼痛及行为进行评估。在探查、放置橡皮障以及牙齿预备和拔牙过程中进行评估。在进行银汞合金或不锈钢冠修复时，两种麻醉技术在行为或疼痛方面均未发现统计学上的显著差异（P = 0.05）。在下颌牙髓切断术和拔牙时，下颌浸润麻醉的效果不如下颌阻滞麻醉（P = 0.05）。未发现有效性与乳牙列或混合牙列所确定的年龄之间存在显著关系。
