12、会向根尖部蔓延,形成牙髓根尖病。牙髓根尖病患者陶床多表现为根尖脓肿,加上炎性渗出物的刺激,患者多表现为咬合痛以及牙齿自发性疼痛等,对患者的咀嚼功能和生活质量产生严重影响口-2。根管填充治疗是当前口腔医学中对牙髓根尖病的主要治疗方式,在有效清除牙根感染和牙髓坏死的同时,还能够和拔牙术互补,从而对牙髓根尖病进行治疗3。当前临床上根管填充指标能够选择的材料种类比较多,那么怎样选择效果最好的填充材料目前尚无明确定论4。氢氧化钙是临床口腔医学常用的一种填充材料,它能够释放出氢氧根离子,快速与蛋白质和脂质结合,增加细菌膜的通透性,对细菌细胞膜产生破坏,导致细胞膜上的酶变形,进而破坏细菌的DNA,达到杀菌效
13、果5o有研究显示,虽然氢氧化钙糊剂能够杀灭细菌,但是其抑制炎症的效果较差,从而影响了患者的康复时间6。因此,为了提升牙髓根尖周病的治疗效果,本文选取朝阳市第二医院2018年1月-2021年1月收治的60例牙髓根尖周病患者作为研究对象,探讨B-磷酸三钙/壳聚糖水凝胶在牙髓根尖周病患者中的应用及对MMP-3表达的影响,现报道如下。1资料与方法1. 1 一般资料选取2018年1月-2021年1月朝阳市第二医院收治的60例牙髓根尖周病患者,将患者依照1 : 1的比例随机分为观察组与对照组,每组30例。纳入标准:经X线与口腔检查确诊为牙髓根尖周病7;根管保持通畅,且牙齿有空洞出现的患者。排除标准:合并其他口腔疾病者;合并严重全身性疾病者;不能配合治疗和随访者。所有患者对本研究知情并签署同意书,本研究经医院伦理委员会批准。1.2 方法所有患者均行常规根管治疗,具体方法为:根据X线片了解患者的根尖情况和牙体硬组织情况,并对患者进行局部麻醉,进行常规开髓、拔髓处理,确定根管工作的长度后实施根管预备操作,清除根管内坏死感染的组织,随后应用0. 9%氯化钠溶液与3%过氧化氢溶液进行反复冲洗,随后应用棉捻将根管吸干。根管无痛之后对照组患者应用氢氧化钙糊剂(生产厂家:武汉沃尔药业有限公司,批准文号:国药准字H42022320,规格:5 g)进行根管消毒与封管处理,在1周之后复诊
