Development of hexagonal boron nitride reinforced light curable dental resin composites

龋齿是全球最普遍的疾病之一，对成人和儿童来说都是一个主要问题。全球牙科修复市场规模已从2014年的125.2亿美元增长到2019年的156亿美元，年均增长率为4.5%1。树脂复合材料是最常用的直接修复材料，用于修复后牙和前牙。尽管现代树脂复合修复体具有令人愉悦的美观性和令人满意的临床寿命，但据报道，每年的失败率为1-4%2，主要是由于骨折或继发性龋齿。更换失败的修复体消耗了大量的临床时间，并给医疗保健系统和患者带来了高昂的财务成本（例如，2020年NHS的成本为62.10英镑）。

Dental caries is one of the most prevalent global diseases that continues to be a major problem for both adults and children. The global restorative dentistry market size has grown from $12.52 billion in 2014 to $15.6 billion in 2019 with an average annual growth rate of 4.5%1.Resin composites are the most commonly used direct restorative material for restoring both posterior and anterior teeth. Despite modern resin composite restorations offer pleasing aesthetics and satisfactory clinical longevity, an annual failure rate of 1-4%2 was reported mainly due to fracture or secondary caries. Replacement of failed restorations consumes a significant amount of clinical time and imposes high financial costs for both health care systems and patient (e.g. £62.10 under NHS for 2020).
