Spectrophotometric Evaluation of Crown Fragment a Year After Reattachment Using Fiber-Reinforced Post A Case Report

Abstract

BACKGROUND: Crown fracture is the most common type offracture and frequently affects the anterior teeth. Crown fractureshave been treated in several ways depending on the location andkind of fracture. This case emphasizes reattachment of fracturedfragments using fiber-reinforced post. Also this case reportunderlines the related aesthetic concerns of reattaching of thefractured fragment.CASE REPORT: Intraorally, examination revealed a complicatedcrown-root fracture of the left maxillary central (#21) and lateralincisor (#22). Moreover, the incisal one-third of the right maxillarycentral incisor (#11) was fractured. Baseline color of the tooth wasrecorded with a spectrophotometer to compare final color of toothtreated with fiber post. The root canal of 21 and 22 was filled witha sealer and gutta-percha. Then, the fiber-reinforced post wasplaced into the canals, and fractured segments were bonded withself-adhesive resin cement. Direct composite resin restoration wasapplied to 11. A year later, a second color measurement wasrecorded, and color differences (∆E) were calculated.RESULT: In 12 months’ follow-up, 11, 21 and 22 wereasymptomatic with satisfying aesthetics, maxillar right incisor wasvital. When crown discoloration was examined, there was clinicallyperceptible but acceptable discoloration without periapicalpathology.CONCLUSION: Fiber reinforced post empowers not only theprotection and reinforcement of tooth structure but also providesesthetic restoration.
