Clinical effects on reattachment and pulpotomy of young crown-fractured and pulp-exposed permanent incisors / 口腔疾病防治

ABSTRACT

Objective @# The present study observed the clinical effects on reattachment and pulpotomy of young crown-fractured and pulp-exposed permanent incisors. @*Methods @#In a one-year retrospective clinical observation study, 30 traumatic intact segments of permanent incisors with crown fracture and pulpal exposure were treated using a pulpotomy and reattachment technique with an enamel-dentin luting agent and composite resin. @*Results @#The number of subsequent visit teeth was 30, 29, 25 at 1, 3, 6 months follow-up respectively. The pulpotomy success rates were 100% at 1 month, 93.1% at 3 months, 93.1% at 6 months. The retention rates using the reattachment technique were 100% at 1 month, 100% at 3 months, 100% at 6 months.@*Conclusion@#Pulpotomy is the preferred method of preserving live pulp after pulpal exposure of young permanent incisors, and the clinical effect is prominent. The fragment reattachment technique is an effective middle- and short-term method for temporary restoration of young crown-fractured permanent incisors.
