The restoration of posterior teeth with composite restoration is a common clinical practice nowadays. Opinions regarding posterior composite restorations vary among dentists. The aim of the present study was to determine the knowledge and opinions of general dental practitioners towards composite resins for posterior teeth restorations.
A questionnaire was devised to elicit information regarding placement of composite restoration in posterior teeth in northern Saudi Arabia. It was distributed to 230 dentists by hand and e-mail. A response rate 136 (59%) was obtained. The questionnaire sought details about case selection criteria for composite restoration, problems associated with composites and reasons for selecting composite restoration in posterior teeth. The data was processed and analysed by SPSS statistical software 19. Frequencies and percentages were calculated for various responses of the participants.
Regarding the selection of composite restoration in posterior teeth, 97% of the dentists did not prefer composite placement for class I restoration with heavy occlusal contacts. 83% of the participants did not select composite for class II restoration. 78% of the respondents opted for restoring composites in small defects. Patients' aesthetic demands (90%), amalgam replacement (22%) and restoration of endodontically treated teeth (42%) were the contributing factors. Regarding the problems associated with posterior composite restorations. Recurrent caries (87%), post-operative sensitivity (84%), restoration fracture (83%) and polymerization shrinkage (73%) were the major problems reported by respondents associated with composite restorations. The other minor concerns were wear (60%), contact build up in case of class II cavity restorations (51%) and isolation for composite restorations (36%). Conservative cavity preparation (78%), aesthetics (73%) and patient preference (65%) were the main reasons for choosing composite restoration for the posterior teeth.
Posterior composites are not popular among dentists practicing in northern Saudi Arabia and there is a need of continued professional education and clinical training for the dentists for posterior composite restorations.
如今，用复合树脂修复后牙是一种常见的临床操作。牙医们对后牙复合树脂修复的看法各不相同。本研究的目的是确定全科牙医对用于后牙修复的复合树脂的了解和看法。
设计了一份问卷，以获取沙特阿拉伯北部后牙复合树脂修复的相关信息。通过手工和电子邮件将问卷分发给230名牙医。获得了136份（59%）的回复率。问卷询问了复合树脂修复的病例选择标准、与复合材料相关的问题以及在后牙选择复合树脂修复的原因。数据由SPSS统计软件19进行处理和分析。计算了参与者各种回答的频率和百分比。
关于后牙复合树脂修复的选择，97%的牙医不倾向于在有重度咬合接触的I类修复中使用复合树脂。83%的参与者不选择II类修复使用复合树脂。78%的受访者选择用复合材料修复小缺损。患者的美学需求（90%）、汞合金替换（22%）和根管治疗后牙齿的修复（42%）是促成因素。关于后牙复合树脂修复相关的问题。复发性龋齿（87%）、术后敏感（84%）、修复体折断（83%）和聚合收缩（73%）是受访者报告的与复合树脂修复相关的主要问题。其他较小的问题是磨损（60%）、II类洞修复时的接触重建（51%）和复合树脂修复的隔离（36%）。保守的洞形预备（78%）、美学（73%）和患者偏好（65%）是选择后牙复合树脂修复的主要原因。
后牙复合树脂修复在沙特阿拉伯北部执业的牙医中并不受欢迎，需要为牙医提供关于后牙复合树脂修复的持续专业教育和临床培训。
