MTA和Vitapex根尖诱导成形术治疗感染型畸形中央尖的成功率对比(1)
【摘要】 目的 对比MTA和Vitapex根尖诱导成形术治疗感染型畸形中央尖的成功率。方法 98例感染型畸形中央尖患者(122颗前磨牙)， 依据根尖诱导药物的不同分为研究组49例(65牙)与对照组49例(57牙)。对照组予以Vitapex根尖诱导治疗， 研究组予以MTA根尖诱导治疗。比较两组患者感染治疗相关指标、诱导周期以及诱导疗效。结果 研究组牙周病变消失时间、咀嚼功能恢复时间、红肿消退时间均短于对照组， 就诊次数少于对照组， 差异具有统计学意义(P<0.05)。研究组诱导周期情况显著优于对照组， 差异具有统计学意义(P<0.05)。研究组组诱导成功率为95.38%， 显著高于对照组的80.70%， 差异具有统计学意义(P<0.05)。结论 予以感染型畸形中央尖患者MTA根尖诱导治疗可缩短感染治疗时间， 并提高诱导成功率， 值得推广。

【Abstract】 Objective To compare success rate between MTA and Vitapex apexification in the treatment of infectious central cusp deformity. Methods A total of 98 patients with infectious central cusp deformity (122 premolar teeth) were divided by different apical induction drugs into research group with 49 cases (65 teeth) and control group with 49 cases (57 teeth). The control group received Vitapex apexification for treatment， and the research group received MTA apexification for treatment. Comparison was made on related indexes in infection treatment， induction duration and induction effect between the two groups. Results The research group had all shorter periodontal lesion disappearance time， masticatory function recovery time， and swelling relief time than the control group， and it had fewer treatment times than the control group. Their difference had statistical significance (P<0.05). The research group had obviously better induction duration status than the control group， and their difference had statistical significance (P<0.05). The research group had much higher induction success rate as 95.38% than 80.70% in the control group， and their difference had statistical significance (P<0.05). Conclusion Implement of MTA apexification for infectious central cusp deformity patients can shorten infection treatment time and improve induction success rate， and this method is worth promoting.

牙齒萌出之后， 牙根并未停止生长， 牙周仍在继续发育， 牙齿发育主要依赖于根尖周的上皮根鞘、根管中生活牙髓以及牙乳头， 但是年轻恒牙多因中央尖折断或是外伤因素引起牙髓病变与恒牙龋病， 继而造成牙根停止发育[1， 2]。目前多对接受根尖诱导成形术治疗的感染型畸形中央尖患者施行Vitapex与MTA根尖诱导， 为明确Vitapex与MTA的根尖诱导效果， 研究针对本院2014年3月～2015年9月收治的98例感染型畸形中央尖患者临床资料进行分析， 现报告如下。
1 资料与方法
1. 1 一般资料 选取2014年3月～2015年9月于本院接受根尖诱导成形术治疗的98例感染型畸形中央尖患者临床资料， 依据根尖诱导药物的不同分为研究组49例(65牙)与对照组49例(57牙)。研究组女26例， 男23例， 年龄9～14岁， 平均年龄(12.35±1.24)岁；对照组女25例， 男24例， 年龄9～15岁， 平均年龄(13.01±1.37)岁。两组均为前磨牙， 共122颗。均经医学伦理委员会批准， 具签署知情同意书。两组患者性别、年龄等一般资料比较差异无统计学意义(P>0.05)， 具有可比性。
1. 2 纳入及排除标准 纳入标准：患牙具保留价值， 损坏程度处于修复范围；无全身性系统疾病且意识清醒；监护人员或患者知情同意；资料齐全。排除标准：患牙并无保留价值；牙根横折或是纵折；牙根长度<1/2；失访或是拒绝配合者。, 百拇医药(刘奕 罗敬中)
