研究目的:

龋病和非龋性疾病常导致牙髓的不可逆性伤害,临床上常用的治疗方法是根管治疗术(root canal treatment, RCT),即去除根管内全部的感染牙髓并用惰性材料严密充填。但是,RCT后患牙由于失去牙髓组织,丧失感觉及防御能力,并因缺乏营养而脆弱、易发生折裂,并最终导致牙齿的缺失,显著缩短了天然牙的使用寿命。因此促进牙髓再生对于口腔健康具有重大意义。牙髓再生术(regenerative endodontic procedures,REP)是通过组织工程技术将细胞、生物活性分子或支架材料植入根管内,重新生长出类似牙髓组织样的富含神经和血管的结缔组织。目前临床REP主要适应证是未发育完成的年轻恒牙根尖周病,针对根尖发育成熟的成人牙髓炎和根尖周炎报道甚少。临床常用的血凝块牙髓再生术存在根尖诱导出血增加患者痛苦、出血量不足和根管钙化闭锁的问题。浓缩生长因子(concentrated growth factor,CGF)是第三代血小板浓聚物,实验研究发现牙髓再生效果CGF优于血凝块,但缺乏临床实验证据。为寻找临床疗效更好的成人牙髓再生术,拟通过临床随机对照试验,对比观察CGF和血凝块两种牙髓再生术在治疗成人成熟恒牙不可复性牙髓炎和根尖周病的治疗疗效,为临床上成人牙髓再生规范操作和推广提供实验依据。  

Objectives of Study:

Caries and non-carious diseases often cause irreversible damage to dental pulp. The commonly used clinical treatment is root canal treatment (RCT), in which all infected pulp is removed and filled with inert materials. However, due to the loss of pulp tissue, sensation and defense ability, and lack of nutrition, the affected teeth are fragile and prone to fracture, which eventually leads to the loss of teeth and significantly shorten the service life of natural teeth. Therefore, promoting pulp regeneration is of great significance for oral health. regenerative endodontic procedures (REP) is the implantation of cells, bioactive molecules, or scaffold materials into root canals through tissue engineering techniques to regenerate pulp-like connective tissue rich in nerves and blood vessels. At present, the main clinical indication of REP is periapical disease in immature permanent teeth, while pulpitis and periapical periodontitis in adults with mature apical development are rarely reported. Endodontics with blood clots commonly used in clinical practice have some problems, such as periapical hemorrhage, increasing patient suffering, insufficient blood loss, and root canal calcification and atresia. The concentrated growth factor (CGF) is the third generation of platelet concentrate. Experimental studies have shown that CGF is better than blood clot in pulp regeneration, but there is a lack of clinical evidence. In order to find a better clinical effect of adult pulp regeneration, a randomized controlled trial was conducted to compare the efficacy of CGF and blood clot in the treatment of adult permanent teeth with irreversible pulpitis and periapical disease, and to provide experimental evidence for the standardized operation and promotion of adult pulp regeneration.
