The success of composite restorations relies on material selection and practitioner-related factors that shape the overall outcome. This study explores the practices of Palestinian general dental practitioners in placing posterior composites, examining the impact of work sector, experience, and gender on their choices.
The study was conducted as an online cross-sectional questionnaire and involved 351 participants, with a response rate of 69.8%. The survey comprised 18 closed-ended questions covering demographics, material selection, and composite placement in special cases, techniques, and factors influencing the choices. Statistical analyses included descriptive statistics, chi-squared tests, and Fisher's exact tests.
Composite was the predominant choice for small-size (83.7%) and large-size posterior cavities (60.4%). Practitioners commonly opted for composite restorations in cases involving occlusal parafunctional activity (60%), poor oral hygiene (78%), and subgingival cavities (72.2%). Only 19.6% and 5.3% reported occlusal and gingival beveling, respectively. Rubber dams for isolation stood at 30%, one-step self-etch adhesives at 44.9%, and the oblique layering technique at 51%. Light-emitting diode curing units were popular (97.55%), but monitoring output with a radiometer was infrequent (93.5%). Tofflemire metal matrix usage was 46.1%, whereas a sectional matrix system was employed by 29.8%. A 2 mm layer exposure to light curing for 20 s was reported by 62%, and 27.75% utilized additional light-curing postmatrix band removal.
The study highlights the need for Palestinian dental professionals to update their clinical approaches in placing composite restorations in posterior teeth. Gender, work sector, and experience influence practitioners' choices, emphasizing the importance of tailored continuing education programs for improving clinical practices.
复合树脂修复的成功依赖于材料选择和影响整体效果的从业者相关因素。本研究探讨巴勒斯坦普通牙科从业者在后牙复合树脂修复方面的操作，考察工作部门、经验和性别对其选择的影响。
本研究采用在线横断面问卷调查，共351名参与者，回复率为69.8%。该调查包括18个封闭式问题，涵盖人口统计学、材料选择以及特殊情况下的复合树脂修复、技术和影响选择的因素。统计分析包括描述性统计、卡方检验和费舍尔精确检验。
复合树脂是小尺寸（83.7%）和大尺寸后牙洞型的主要选择（60.4%）。从业者通常在存在咬合副功能活动（60%）、口腔卫生差（78%）和龈下洞型（72.2%）的情况下选择复合树脂修复。分别只有19.6%和5.3%的人报告进行了咬合和牙龈斜面制备。隔离用橡皮障的使用比例为30%，一步自酸蚀粘结剂为44.9%，斜向分层技术为51%。发光二极管固化灯很受欢迎（97.55%），但使用辐射计监测输出的情况很少（93.5%）。托菲米尔金属成形片的使用率为46.1%，而分段成形片系统的使用率为29.8%。62%的人报告2毫米厚的树脂层光照固化20秒，27.75%的人在去除成形片带后进行额外的光照固化。
该研究强调巴勒斯坦牙科专业人员需要更新后牙复合树脂修复的临床方法。性别、工作部门和经验会影响从业者的选择，这凸显了制定针对性继续教育项目以改善临床操作的重要性。
