To determine the opinions and current methods used in placing posterior composite restorations by general dental practitioners.
The study was completed by general dental practitioners randomly selected from across the UK.
A questionnaire was devised to gain this information. It was sent to 500 UK dentists chosen at random from the general dental register, with an explanatory letter and reply-paid envelope.
Two hundred and sixty-seven replies were received. Sixty-one percent of dentists felt amalgam use had decreased over the last five years, 75% felt posterior composite use had increased. Regarding choice of posterior material, almost all cited clinical indication as the most influential factor while patient's aesthetic demands (89%),wish for a certain material (78%) and the dentist's confidence using a certain restorative material (76%) were contributing factors. Regarding the techniques used, contemporary techniques were employed although there was confusion regarding the need for rubber dam and the most appropriate method of lining the cavity. A case scenario of a pregnant patient who required treatment found that 66% of respondents would place a restoration other than a temporary dressing, with 16% placing an amalgam restoration.
The majority of dentists surveyed place load bearing posterior composite restorations regularly. Their choice of restorative material is influenced by clinical indications and the patient's aesthetic demands. The techniques used were appropriate, although there was confusion around the need for rubber dam and the most appropriate method to line the cavity. There was also confusion in relation to the most appropriate materials for use in pregnancy.
确定普通牙医在放置后牙复合树脂修复体时的意见和当前使用方法。
该研究由英国各地随机选择的普通牙科医生完成。
设计了一份问卷来获取这些信息。它被寄给了 500 名从普通牙科登记册中随机选择的英国牙医，附有一封说明信和回邮信封。
共收到 267 份回复。61%的牙医认为过去五年银汞合金的使用量减少了，75%的牙医认为后牙复合树脂的使用量增加了。关于后牙材料的选择，几乎所有的牙医都将临床指征列为最具影响力的因素，而患者的审美要求（89%）、对某种材料的愿望（78%）和牙医对某种修复材料的信心（76%）是次要因素。关于使用的技术，虽然对于橡皮障的必要性和最适合衬里腔的方法存在混淆，但仍采用了现代技术。对于需要治疗的孕妇的案例场景，发现 66%的受访者会放置除临时敷料以外的修复体，其中 16%会放置银汞合金修复体。
大多数接受调查的牙医经常放置承重后牙复合树脂修复体。他们对修复材料的选择受到临床指征和患者审美需求的影响。使用的技术是合适的，尽管对于橡皮障的必要性和最适合衬里腔的方法存在混淆。对于在怀孕期间使用的最合适材料也存在混淆。
