本文讨论了下颌门齿区城的软、硬组织的神经分布。作者通过试验证实了中切牙为双侧神经支配。试验方法: 1.软组织无痛法:20名病人,每人用加有1:80,000肾上腺:素的2%利多卡因1.5毫升,作一针下颌传导麻醉,十分钟后,用一无菌针头去试验针刺感以决定无痛的范围。检查区城为唇周围颏部的皮肤;下颌唇沟及相应的舌沟的粘膜表面。2.牙髓感觉法:将40名具有完整下切牙的病人用加有1:80,000肾上腺素的2%利多卡因1.5毫升作下齿槽和舌神经传导麻
This article discusses the neural distribution of the soft and hard tissues in the city of the mandibular incisors. The author confirmed by experiments that the incisors are bilateral nerve innervation. Test methods: 1. Soft tissue painlessness: 20 patients, each with a 1: 80,000 adrenal: 2% lidocaine 1.5 ml, for a needle mandibular conduction anesthesia, ten minutes later, with a sterile needle To test the acupuncture to determine the painless range. Check the city area for the chin around the lips of the skin; mandibular lip groove and the corresponding lingual ditch mucosal surface. 2. Endodontic method: 40 patients with intact inferior incisors were treated with 1.5 ml of 2% lidocaine with 1: 80,000 epinephrine for the alveolar and lingual nerve conduction
