To investigate the selection and use of materials and techniques for core buildup, indirect restorations, and fixed prosthodontics by general dentists in New Zealand.
A questionnaire comprising 19 sections and 125 questions was distributed via mail to 351 general dentists in New Zealand who were selected from the Dental Council of New Zealand's 2016 register.
The majority of the respondents (68.8%) reported using resin composite light-cured materials for the core buildup of vital posterior teeth. A large number of respondents (52%) did not use dentine pins, with the majority of them (25%) being recent graduates (<10 years). Fibre posts were used by 61.6% of the dentists surveyed. The majority of dentists (54.6%) reported using addition-cured silicone impression material for crown and bridge impressions. Glass-ionomer cements (37.5% of participants) and resin-modified glass-ionomer cements (35.8%) were the most common luting cements used. Direct resin composite veneers were the preferred material of choice rather than indirect restoration of anterior teeth (40.4%).
The study showed that New Zealand dentists surveyed are using current state-of-the-art materials and techniques, with their choice of material being greatly influenced by clinical indications and patients aesthetic demands.
调查新西兰普通牙医在核桩修复、间接修复和固定义齿修复中材料和技术的选择与使用情况。
通过邮件向从新西兰牙科协会2016年登记册中选取的351名普通牙医发放了一份包含19个部分和125个问题的问卷。
大多数受访者（68.8%）报告在活髓后牙的核桩修复中使用树脂复合光固化材料。大量受访者（52%）未使用牙本质钉，其中大多数（25%）是刚毕业的牙医（<10年）。61.6%的受访牙医使用纤维桩。大多数牙医（54.6%）报告在冠桥印模中使用加成型硅橡胶印模材料。玻璃离子水门汀（37.5%的参与者）和树脂改性玻璃离子水门汀（35.8%）是最常用的粘结水门汀。直接树脂复合贴面是前牙修复的首选材料，而非间接修复（40.4%）。
该研究表明，接受调查的新西兰牙医正在使用当前最先进的材料和技术，他们对材料的选择受临床适应证和患者美学需求的影响很大。
