原位断冠再接技术联合牙髓切断术治疗年轻恒前牙复杂冠根折的临床疗效研究
Clinical efficacy of in-situ crown reattachment technique combined with pulpotomy in the treatment of complica-ted crown-root fractures of young permanent anterior teeth
摘要
Abstract
Objective This study aimed to evaluate the clinical application value of in-situ crown reattachment tech-nique combined with pulpotomy in the treatment of complicated crown-root fractures in young permanent anterior teeth.Methods A prospective study was conducted on 50 children with complicated crown-root fractures in young perma-nent anterior teeth,who were treated at the Pediatric Dentistry Department,Hospital of Stomatology,Xi'an Jiaotong Uni-versity from June 2023 to June 2024.All patients underwent in-situ crown reattachment technique combined with pulpot-omy.Clinical examinations,radiographic evaluations,and subjective satisfaction surveys(using a Likert scale of 1-10)were conducted at 1,6,and 12 months postoperatively.Data were analyzed using SPSS 23.0.Results The loss-to-follow-up rate was 12％(6/50),with 44 cases complet-ing the 12 months of evaluation.The clinical success rate was 93.18％(41/44),and the radiographic success rate was 97.73％(43/44).The subjective satisfaction scores showed a significant improvement in masticatory function from 7.03±0.52 at 1 month to 8.07±0.92 at 12 months postop-eratively(P＜0.05),whereas the scores for aesthetics,comfort,and quality-of-life impact showed no statistically signifi-cant differences(P＞0.05).Conclusion In-situ crown reattachment technique combined with pulpotomy effectively treats complicated crown-root fractures in young permanent anterior teeth,demonstrating a high short-term clinical suc-cess rate,significantly improved masticatory function,and minimally invasive preservation of pulp vitality and root de-velopment potential.This technique provides an optimized treatment option for dental trauma in children,although its long-term efficacy requires further validation.关键词
