修复牙齿深龋损伤中丢失的牙本质是一种常规和常见的治疗方法,涉及使用基于钙或硅基矿物聚集体的无机粘固剂。这种粘固剂留在牙齿中并且不能降解,因此正常的矿物质体积永远不会完全恢复。在这里,我们描述了一种新的,生物学的方法,牙本质修复,刺激修复性牙本质的自然形成,通过动员居民干细胞在牙髓。生物可降解的临床批准的胶原海绵用于递送低剂量的小分子糖原合成酶激酶(GSK-3)拮抗剂,其促进修复性牙本质形成的自然过程以完全恢复牙本质。由于载体海绵随时间降解,牙本质取代降解的海绵,导致完全有效的自然修复。因此,这种简单、快速的自然牙齿修复过程可能为临床牙齿修复提供一种新的方法。
The restoration of dentine lost in deep caries lesions in teeth is a routine and common treatment that involves the use of inorganic cements based on calcium or silicon-based mineral aggregates. Such cements remain in the tooth and fail to degrade and thus normal mineral volume is never completely restored. Here we describe a novel, biological approach to dentine restoration that stimulates the natural formation of reparative dentine via the mobilisation of resident stem cells in the tooth pulp. Biodegradable, clinically-approved collagen sponges are used to deliver low doses of small molecule glycogen synthase kinase (GSK-3) antagonists that promote the natural processes of reparative dentine formation to completely restore dentine. Since the carrier sponge is degraded over time, dentine replaces the degraded sponge leading to a complete, effective natural repair. This simple, rapid natural tooth repair process could thus potentially provide a new approach to clinical tooth restoration.
