Clinical effects on reattachment and pulpotomy of young crown ⁃ fractured and pulp ⁃exposed permanent inci⁃ sors

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 pulpot⁃ omy and reattachment technique with an enamel⁃dentin luting agent and composite resin. Results The number of sub⁃ sequent 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 tech⁃ nique is an effective middle⁃ and short⁃term method for temporary restoration of young crown⁃fractured permanent inci⁃ sors.
