摘要
目的探讨多学科联合治疗年轻恒上前牙复杂冠根折的效果。方法选取2018年1月至12月因恒上前牙复杂冠根折来我院接受治疗的42例患者为研究对象,根据牙髓状况选择进行牙髓切断术+正畸牵引暴露断面+美学树脂修复(活髓保存+树脂修复组,n=21),或根尖诱导成形术+正畸牵引暴露断面+玻璃陶瓷冠修复(根尖诱导+冠修复组,n=21)。比较两组的治疗效果。结果所有患者均顺利完成了整个治疗过程,且对治疗效果表示满意,自修复后即刻至修复后1年的随访中,未发生牙齿松动、牙髓炎/根尖周炎、修复体脱落、破损等情况。以对侧同名牙为对照,修复后即刻、1个月、1年,两组患牙及对侧同名牙组的菌斑指数(PLI)、出血指数(BI)比较,差异无统计学意义(P>0.05)。同修复完成即刻相比,两组患牙及对侧同名牙组在修复后1个月、1年均经历了牙龈相对切端位置下移的过程。两组的修复体在边缘适合性、外形、颜色匹配、表面质地方面均有良好的表现,组间比较,差异不显著(P>0.05)。修复后即刻、1个月、1年,两组患者对修复体外形颜色和舒适度的满意度评分随时间延长呈上升趋势,但组间比较,差异不显著(P>0.05)。结论多学科联合治疗年轻恒上前牙的复杂冠根折可最大程度保留患牙的牙体牙髓组织,确保牙周组织健康的同时获得持久的美学效果。
Objective To investigate the effect of multidisciplinary therapy on complex crown-root fracture of the young anterior permanent teeth.Methods Forty-two patients who received treatment in our hospital due to complex crown-root fracture of the anterior permanent teeth from January to December 2018 were selected as the research objects.According to the dental pulp status,pulpotomy+orthodontic traction and exposure section+aesthetic resin restoration(living pulp preservation+resin restoration group,n=21),or apical induction plasty+orthodontic traction exposed section+glass ceramic crown repair(apical induction+crown repair group,n=21)were selected.The therapeutic effects of the two groups were compared.Results All patients successfully completed the entire treatment process and were satisfied with the therapeutic effect.No loosening of teeth,pulpitis/periapical inflammation,loss of prosthesis or damage occurred during follow-up from the immediate after repair to 1 year after repair.Taking the opposite homonymous tooth as the control,there were no statistically significant differences in plague index(PLI)and bleeding index(BI)between the two groups of affected teeth and the opposite homonymous tooth group immediately,1 month and 1 year after restoration(P>0.05).Compared with the immediate completion of the restoration,the affected teeth in the two groups and the opposite homonymous teeth group experienced a downward movement of the position of the gingival relative to the cutting end within 1 month and 1 year after the restoration.The restorations of the two groups showed good performance in the aspects of marginal fitness,shape,color matching and surface texture,and there were no significant differences between the two groups(P>0.05).Immediately,1 month and 1 year after restoration,the satisfaction scores of the two groups on the shape color and comfort of the restoration showed an increasing trend with the extension of time,but there were no significant differences between the two groups(P>0.05).Conclusion Multidisciplinary therapy of complex crown-root fracture in the young anterior permanent teeth can preserve the dental pulp tissue of the affected tooth to the greatest extent,ensure the health of periodontal tissue and obtain lasting aesthetic effects.
