One of the common forms of dental injury is anterior crown fractures, which mainly affect teenagers and young adults. Fractures of the coronal portion of the permanent incisors characterize 18-22% of total traumatic injuries to dental hard tissues, of which 96% of them comprise the maxillary incisors. An uncomplicated fracture of the crown is one of the most common types of dental traumatic injury. Dental trauma has an emotional impact on the patient's overall health and can seriously harm to the dentition. The treatment, as well as prognosis of the fracture of the coronal portion, is a major challenge for a dentist because it has to accomplish various parameters like the need to obtain an aesthetical result that approaches itself to its natural form and measurement, opaqueness and translucency of the original tooth structure in obtaining an effective restoration. It is suggested that reattachment of the fractured fragment is the best procedure for restoring an uncomplicated crown fracture, if a fragment is present. Fragment reattachment offers superior aesthetics and function compared to composite restorations, preserving the tooth's natural characteristics, like the tooth's true shape, colour, intensity, and surface texture. Success depends on the fracture line's direction and location; simple enamel or enamel-dentin fractures are ideal. However, reattached fragments remain vulnerable to subsequent trauma. The reattached fragments are susceptible to further fracture when the restored teeth undergo further trauma. The resistance of the fractured teeth that have been reattached is the subject of the majority of concerns. Preconditioning the fractured fragments with remineralizing agents may aid in hydration. Thus, a study will be conducted to evaluate the resistance of the fracture of a tooth that is reattached and pre-treated with remineralizing agents such as sodium fluoride and casein phosphopeptide-amorphous calcium phosphate and further reattached using one of the self-adhesive bioactive composite.
牙齿损伤的常见形式之一是前牙冠折，主要影响青少年和年轻成年人。恒牙切牙冠部骨折占牙硬组织全部创伤性损伤的18%-22%，其中96%为上颌切牙。冠部简单骨折是最常见的牙齿创伤性损伤类型之一。牙齿创伤会对患者的整体健康产生情感影响，并可能严重损害牙列。冠部骨折的治疗以及预后对牙医来说是一项重大挑战，因为在进行有效修复时，需要达到各种参数，比如获得接近自然形态和尺寸的美学效果、原牙结构的不透明度和半透明度。如果存在骨折碎片，建议将骨折碎片重新附着是修复简单冠折的最佳方法。与复合树脂修复相比，碎片重新附着能提供更好的美学效果和功能，保留牙齿的自然特征，如牙齿的真实形状、颜色、亮度和表面纹理。成功与否取决于骨折线的方向和位置；单纯釉质或釉质-牙本质骨折是理想的。然而，重新附着的碎片仍易受到后续创伤的影响。当修复后的牙齿遭受进一步创伤时，重新附着的碎片容易再次骨折。重新附着的骨折牙齿的抗力是大多数关注的主题。用再矿化剂预处理骨折碎片可能有助于水合作用。因此，将进行一项研究，以评估用氟化钠和酪蛋白磷酸肽-无定形磷酸钙等再矿化剂重新附着并预处理，然后使用一种自粘生物活性复合材料进一步重新附着的牙齿骨折的抗力。
