Clinical application of glass fiber post in repair of young permanent teeth after traumatic dental injury

Objective:To explore the clinical application efficacy of glass fiber post in repair of young permanent teeth after traumatic dental injury.Methods:64 children with young permanent teeth after traumatic dental injury in stomatological hospital of Jilin university from June 2007 to June 2009 were selected,and 90 teeth with diseases were included in the study,X-ray tomography was used to observe the developmental situation of root of tooth,60 teeth with diseases and undeveloped root received vital pulpotomy and apexification by Vitapex;after the formation of root of tooth,perfect root canal therapy was carried out.The 90 teeth with diseases were divided into experimental group(group A) and control group(group B),50 teeth in group A were treated with resin nuclear crown repair by glass fiber post,and 40 teeth in group B were treated with resin nuclear crown repair by threaded nail,the teeth in the two groups were followed up regularly,the clinical application efficacies of the two groups were observed.Results:After one year,among the 50 teeth treated with resin nuclear crown repair by glass fiber post,48 teeth were repaired successfully,the success rate was 96.0%.Among the 40 teeth treated with resin nuclear crown repair by threaded nail,33 teeth were repaired successfully,the success rate was 82.5%,there was significant difference between the two groups(P0.05).Conclusion:The clinical efficacy of glass fiber post in repair of young permanent teeth after traumatic dental injury is ideal,and the method can satisfy the clinical demand.
