The use of rubber dam for endodontic treatment in New Zealand was analysed by a national survey of general dental practitioners. The response rate was 79 percent. Rubber dam was used routinely by 57 percent, its use increasing among practitioners graduating since 1969. A greater percentage of practitioners with less than 10 years experience used rubber dam than did more experienced practitioners. Use of rubber dam was associated with sodium hypochlorite and EDTA as canal irrigants. Reamers were the favoured hand instrument of non-users of rubber dam. No significant differences were found in the canal obturation techniques of users and non-users, but rubber dam users used the long-cone paralleling method of radiography significantly more than non-users. Practitioners in solo practice used rubber dam significantly less than those in group practice. Rubber dam users attended significantly more refresher courses in endodontics than non-users.
通过对新西兰普通牙科医生的全国性调查，分析了橡皮障在牙髓治疗中的使用情况。回复率为79%。57%的医生常规使用橡皮障，自1969年以来毕业的医生中其使用量在增加。经验不足10年的医生使用橡皮障的比例高于经验更丰富的医生。橡皮障的使用与次氯酸钠和乙二胺四乙酸作为根管冲洗剂有关。锉是不使用橡皮障的医生所青睐的手持器械。在根管充填技术方面，使用者和非使用者之间未发现显著差异，但使用橡皮障的医生使用长锥平行投照法进行影像学检查的比例明显高于非使用者。个体执业的医生使用橡皮障的比例明显低于团体执业的医生。使用橡皮障的医生参加牙髓病学进修课程的次数明显多于非使用者。
