An avulsion is a severe dental injury characterized by the complete displacement of a tooth from its socket, often resulting in a compromised prognosis. One of the key factors influencing the success of reimplantation is the extraoral dry time, which refers to the duration the tooth remains outside of the socket. Prolonged dry time significantly impairs the viability of the periodontal ligament cells, crucial for successful healing and reattachment. Despite various protocols and treatment strategies developed to manage avulsed teeth, no single approach addresses all treatment needs effectively, particularly in cases of delayed reimplantation. Simvastatin, an anti-lipidemic drug, has demonstrated pleiotropic effects that extend beyond cholesterol lowering. These effects include anti-inflammatory properties, promotion of bone regeneration, and enhancement of periodontal ligament cell survival. Such actions suggest that simvastatin may have a beneficial role in improving outcomes following the delayed reimplantation of avulsed teeth. This case series proposes the use of simvastatin as an adjunctive treatment for avulsed teeth along with platelet-rich fibrin and hydroxyapatite, particularly in situations where reimplantation is delayed. By mitigating inflammation and stimulating tissue regeneration, simvastatin may help counteract the damage caused by prolonged extraoral dry time. Its potential to promote periodontal ligament cell survival and enhance healing processes could improve the prognosis of reimplantation, even in cases where traditional treatment alone would be less effective. Given these promising properties, simvastatin may represent a valuable addition to the treatment protocol for avulsed teeth with extended dry times. However, further clinical studies and trials are necessary to validate its efficacy and establish a clear role in the management of delayed reimplantation.
牙脱位是一种严重的牙齿损伤，其特征是牙齿从牙槽窝完全脱出，通常会导致预后不良。影响再植成功的关键因素之一是牙体外干燥时间，即牙齿留在牙槽窝外的时长。延长的干燥时间会显著损害牙周膜细胞的活力，而牙周膜细胞对成功愈合和再附着至关重要。尽管已制定了各种方案和治疗策略来处理脱位牙，但没有一种单一方法能有效满足所有治疗需求，尤其是在延迟再植的情况下。辛伐他汀是一种抗血脂药物，已显示出多种作用，其作用范围超出了降低胆固醇。这些作用包括抗炎特性、促进骨再生以及提高牙周膜细胞存活率。这些作用表明，辛伐他汀在改善脱位牙延迟再植后的预后方面可能具有有益作用。本病例系列提出将辛伐他汀与富含血小板的纤维蛋白和羟基磷灰石一起用作脱位牙的辅助治疗，特别是在再植延迟的情况下。通过减轻炎症和刺激组织再生，辛伐他汀可能有助于抵消延长的牙体外干燥时间所造成的损害。其促进牙周膜细胞存活和增强愈合过程的潜力可改善再植的预后，即使在单独使用传统治疗效果较差的情况下也是如此。鉴于这些有前景的特性，辛伐他汀可能是延长干燥时间的脱位牙治疗方案中的一个有价值的补充。然而，需要进一步的临床研究和试验来验证其疗效，并确定其在延迟再植管理中的明确作用。
