The purpose of this study was to obtain data on current approaches for the restoration of endodontically treated teeth among general dental practitioners (GDPs) in Manchester, United Kingdom.
A questionnaire containing 19 single-answer, multiple-choice type questions was mailed to 503 GDPs practising in the Greater Manchester area in January 2002. An explanatory covering letter and a stamped addressed return envelope were enclosed. The data obtained were processed using SPSS statistical software.
Three hundred and fifty-one (70%) of the practitioners responded to the questionnaire. The restoration of root-filled teeth was normally undertaken within 1-2 weeks of completing root canal therapy by 63% of the practitioners. Only 35% of the GDPs used posts routinely in the restoration of root-filled anterior teeth; the corresponding figure for posterior teeth was 15%. While a cast, precious metal post was the preferred choice in the restoration of anterior teeth, the use of prefabricated posts and related techniques predominated in the restoration of posterior teeth. Composite resin was the most popular choice of material for core build-up procedures in anterior teeth. Amalgam tended to be favoured for core build-ups in posterior teeth. The majority of the practitioners (56%) routinely restored root-filled anterior teeth by means of porcelain-fused-to-metal crowns. Seventy-three per cent of the GDPs preferred to restore root-filled posterior teeth by means of a full veneer crown.
The results of this study suggest that the practitioners surveyed had a sound understanding of the principles involved in the restoration of endodontically treated teeth, with the possible exception of the need to establish a durable coronal seal as soon as possible after the placement of a root filling.
本研究旨在获取英国曼彻斯特普通牙科医生(GDPs)对根管治疗后牙齿修复的当前方法的数据。
2002年1月,向大曼彻斯特地区执业的503名GDPs邮寄了一份包含19个单项选择题的问卷。随附一封解释性的附信和一个贴好邮票并写好地址的回邮信封。使用SPSS统计软件对获得的数据进行处理。
351名(70%)从业者回复了问卷。63%的从业者通常在完成根管治疗后的1 - 2周内对根管充填后的牙齿进行修复。只有35%的GDPs在根管充填前牙修复中常规使用桩;后牙的相应比例为15%。在前牙修复中,铸造贵金属桩是首选,而后牙修复中预制桩及相关技术的使用占主导。复合树脂是前牙核成形术最常用的材料选择。银汞合金在后牙核成形术中更受青睐。大多数从业者(56%)常规通过烤瓷熔附金属冠修复根管充填后的前牙。73%的GDPs更喜欢用全冠修复根管充填后的后牙。
本研究结果表明,接受调查的从业者对根管治疗后牙齿修复所涉及的原则有充分的理解,但在根管充填后尽快建立持久的冠部封闭这一点上可能除外。
