To investigate the selection and use of direct restorative materials, endodontic techniques adopted, and approaches to bleaching 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, at random, from the Dental Council of New Zealand's 2016 register.
A total of 204 questionnaires were returned, of which 188 were usable. Direct resin composite was the most commonly used material for occlusoproximal cavity restorations in premolars (93.7%) and permanent molars (85.2%). Resin-modified glass ionomer cements (34%) and resin composite materials (31.4%) were more commonly used in the restoration of deciduous molars. Home-based vital bleaching was provided by a significant number of dentists (86%), while only 18% provided practice-based bleaching. Cold lateral condensation was the most commonly used obturation technique (55.8%), and 83% of respondents reported using rubber dam for treatments.
The findings from this study indicate that dentists in New Zealand are adapting to new materials and technologies to provide high quality care to their patients. Aesthetic treatments such as bleaching have become an integral part of general dental practice.
调查新西兰普通牙医对直接修复材料的选择与使用、所采用的牙髓治疗技术以及牙齿漂白方法。
通过邮件向从新西兰牙科委员会2016年登记册中随机选取的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。
共收回204份问卷，其中188份可用。直接树脂复合材料是前磨牙（93.7%）和恒牙磨牙（85.2%）咬合邻面洞修复最常用的材料。树脂改性玻璃离子水门汀（34%）和树脂复合材料（31.4%）在乳牙磨牙修复中使用更为普遍。大量牙医（86%）提供家庭内活髓漂白，而只有18%提供诊所内漂白。冷侧方加压充填是最常用的充填技术（55.8%），83%的受访者报告在治疗中使用橡皮障。
本研究结果表明，新西兰的牙医正在采用新材料和新技术，为患者提供高质量的治疗。牙齿漂白等美容治疗已成为普通牙科治疗中不可或缺的一部分。
