Devitalisation pulpotomy失活干髓术蔺龙,Devitalisation pulpotomy/plptmi/牙髓切断术,This is a two-stage procedure involving the use of paraformaldehyde/,prf:mldhaid/(多聚甲醛)to fix the entire coronal/krnl/（1头冠的，冠的 2冠向的）and radicular/rdikjul/（根的）pulp tissue。这是一个涉及利用多聚甲醛来固定整个根髓和冠髓组织的两步骤过程。,The paraformaldehyde paste/peist/（糊剂，膏剂）most commonly used has the following composition最常用的多聚甲醛糊剂有以下组成。,The paste is placed over the exposure/ikspu/(1暴露2曝光3照射)and scaled/skeild/(剥刮)in the tooth for 1-2week。多聚甲醛糊剂置于暴露的被剥刮干净的露髓表面1-2周。,Paraformaldehyde（多聚甲醛）10gLignocaine/lin,kein/(利诺卡因，赛罗卡因)0.06gCarmine(color)/k:main/(卡红，胭脂红)0.01gCarbowax/k:buwks/(多乙烯二醇，聚氧乙烯二醇)1.3gPropylene/prupili:n/(丙烯)glycol/laikl/(1脂肪族二元醇类2乙二醇，甘醇)丙二醇 0.5ml,Formaldehyde/f:mldihaid/(甲醛)gas liberated from the paraformaldehyde permeates/p:mieit/（1渗透2渗透物）through the coronal and radicular pulp,fixing the tissues。从多聚甲醛糊剂中释放出来的甲醛气体渗入根髓和冠髓来固定牙髓组织。,On the second visit,the pulpotomy is carried out（without the need for local analgesia/,nldi:zj/（1痛觉缺失2止痛术）and an antiseptic/,ntiseptik/（1抗菌的2防腐剂）paste is place over the radicular pulp before restoring the tooth。在第二步中实施牙髓切断术（无需局麻药），同时在保存患牙之前必须在根髓上涂上防腐抗菌剂。,An alternative/:lt:ntiv/（1更迭的2互生的）method is to perform a vital pulpotomy at the first visit,devitalise the radicular pulp with paraformaldehyde paste for 1-2 weeks and,at the second visit replace the paste with an antiseptic paste and restroe the tooth。在第一步中重复使用上面的方法来实施活髓切段术，用多聚甲醛剂1-2周使牙根髓失活，在第二步中，用防腐抗菌剂替换多聚甲醛糊剂来保存患牙。,A related method employs a different paraformaldehyde-containing material in a one-stage procedure一相关的疗法在一个疗程中使用了不同的含有多聚甲醛糊剂的材料,Following vital pulpotomy,the paste is placed over the radicular pulp stumps/stmp/(残肢，残株),and the tooth is restored。随着活髓切断术的完成，把干髓剂置于根髓的残株上，患牙就保存下来了。,
